When you look up at the night sky, what comes to mind? For Christine Ye, all she can think about are the mysteries of the universe(宇宙).
Thanks to her study of black holes and neutron stars(中子星), the 17-year-old at Eastlake High School in Washington, the United States, won the top award at the 2022 Regeneron Science Talent Search. It’s one of the oldest and best-known science competitions for US high school students. It focuses on creativity, following the rules of science, and a person’s potential(潜力) to become a leader in science.
Ye’s research is based on data from the Laser Interferometer Gravitational-wave Observatory (LIGO, 激光干涉引力波天文台) . She used the data to solve one of LIGO’s hardest puzzles(谜题).
In 2019, researchers found ripples(涟漪) in space-time. The ripples were caused by the collision(碰撞) of a black hole with an unknown object that was 2.6 times as large as Earth’s sun. By analyzing(分析) the data, Ye and her co-writer, Northwestern University researcher Maya Fishbach, pointed out that the unknown object could be a fast-spinning neutron star.
They also found that a fast-spinning neutron star could be very large, but still smaller than a black hole.
Thanks to the research, Ye won first place and $250,000 (about 159,000 yuan). “I’m totally in shock,” Ye told Geek Wire after the results came out. “It feels amazing.” She also said working with scientists at Northwestern University has been a “once-in-a-lifetime experience”.
Ye plans to study astrophysics(天体物理学) in college, especially gravitational-wave(引力波) astronomy. “It’s a very young field,” she said. “It would be really nice to grow up with the field as it develops.”

Stars produce energy every second. When a star fails to make enough energy, its centercollapses. If the star is big enough, it will form a black hole. If no, it will become a smaller and heavier star. During their lives, black holes will "eat" anything that comes close, causing them to grow bigger and bigger. Smaller black holes can move around space at the speed of 400,000 kilometers per hour. But the bigger black holes that are found in the center of galaxies usually don't move. Besides, black holes don't last forever. According to Stephen Hawking, black holes will get smaller over time if they don't "eat" enough. But we've never actually seen this happen.
Black holes are among the most exciting mysteries in the universe. They have drawn even more attention since the first photo of a black hole came out on April 10, 2019. Black holes are objects in space with extremely strong gravity. They take in everything around them—even light. They are made up of three parts: the accretion disk, the event horizon, and the singularity(奇点). The accretion disk is the outer ring of a black hole. If matter enters this area, it will move around the black hole before being taken in. The event horizon is the side of a black hole. Nothing can run away after being taken into the event horizon. This is why we see nothing but darkness when we look at black holes. Finally, there's the middle of the black hole---the singularity. It has a lot of mass and takes up most of the black hole's weight.
To better understand black holes, we can look to their opposites—white holes. While mass can only enter a black hole, it can only leave through a white hole, One theory is that black holes will turn into white holes when they finally disappear. However, this process takes millions of years, and humans have not seen it happen yet. Another theory is that white and black holes are connected. They form a link between different universes. So in theory, if you jump into a black hole and survive, you might travel to another universe.
While white holes might be just a theory now, remember that black holes were once just a theory as well. Now, less than 50 years later, we have photographed one. If white holes are found one day, we might have to rethink our understanding of the universe.

On March 14, 2018,Stephen Hawking, the world-famous British scientist, died at 76 in Cambridge, UK.
Hawking is considered by many to be the greatest scientist in history since Albert Einstein. He came up with the theory (理论) that the universe (宇宙) began with the big bang (大爆炸) and will end in black holes. His theories became the base for a lot of later research. He also wrote books to help common people understand the universe. His most famous book is A brief History of Time (时间简史),which has sold more than 10 million copies around the world.
Besides his scientific achievements, Hawking was also someone that had a strong will and optimistic attitude (乐观心态).
When Hawking was 21, he was diagnosed (诊断) with a serious illness that stopped him from walking and talking. Later in life, he had to sit in a wheelchair and speak using a computer. But this didn’t stop him from living a meaningful and colorful life. He traveled around the world for science meetings, visiting every continent (大洲), including Antarctic(南极洲). In 1985, he took a train trip around China. He was also a fan of pop culture and appeared on TV shows such as Star Trek (从星际迷航) and the Big Bang Theory (生活大爆炸). He celebrated his 60th birthday by going up in a hot-air balloon. He hoped to travel into space one day.

China has just opened its FAST radio telescope (射电望远镜) to international scientists. It means scientists across the world can apply for using the telescope to do astronomical observations.
FAST is short for Five-hundred-meter Aperture Spherical radio Telescope. It was completed in September 2016 and it officially began operating in January 2020. Measuring 500 meters in diameter. FAST is the world’s largest single-dish radio telescope, and is 10 times more sensitive than the 100-meter Radio Telescope Effelsberg in Germany.
The major scientific task of the telescope is the observation of pulsars (脉冲星). The study of pulsars can help to confirm the existence of gravitational radiation (引力辐射) and black holes, and help solve many other major questions in physics. Another major scientific goal of FAST is to search for life outside the Earth.
The telescope is located in a naturally deep and round karst depression (喀斯特洼地) in southwest China’s Guizhou Province. The first advantage of the selected site is the altitude (海拔). The average altitude of Guizhou is about 1,100 meters. Generally, the higher the altitude, the more the telescope can observe. Secondly, the radio telescope needs to have a “big pan” to receive better signals. The huge natural depression could reduce the difficulty of construction. Moreover, the selected site in Guizhou is far away from cities, and has a low population density, which reduces the interference (干扰) caused by wireless devices such as TVs, mobile phones and radios from human activities.
So far, FAST has found over 300 pulsars. Experts predict that the number could reach 1,000 in five years and that the telescope could find and locate the first pulsar outside the Galaxy.
14.Who can use FAST?
A.Chinese scientists. B.Scientists from all countries.
C.Soldiers and policemen. D.All Chinese citizens.
15.When did FAST start working officially?
A.In 2015. B.In 2016. C.In 2020. D.In 2021.
16.What do we know from the fourth paragraph?
A.The advantages of the selected site for FAST.
B.Guizhou Province has the highest altitude in China.
C.The reasons for using mobile phones less.
D.FAST is built in a pan-shape place to keep people out.
17.What do scientists think FAST will probably be able to do in the future?
A.Identify more than 300 pulsars in five years.
B.Discover the first pulsar outside the Galaxy.
C.Locate wireless devices around the world.
D.Collect all kinds of sounds in space.
18.Where can you probably read this passage?
A.Human and Nature B.Geography 101
C.Animals and Plants D.Scientific World

What do black holes look like? Human beings have wanted to know about it for a long time. In 2019, we finally got the answer. They look like dark circles with a bright ring around the outside.
Scientists took the world’s first photo of a black hole. Scientists didn’t use a camera to take the picture. They used eight radio telescopes in different places around the world. Telescopes got signals (信号) from the black hole. Scientists used computers to process (处理) the signals. It took them two years to get the final picture.
The black hole is very far from Earth—about 55 million light years away. One light year is the journey that light travels in one year. One light year is about 9 trillion (万亿) kilometers.
This isn’t the only black hole in the universe. In fact, scientists believe every large galaxy (星系) has a big black hole at its center. The one in our galaxy is called Sagittarius A.
Black holes are some of the most mysterious (神秘的) things in the universe. This photo can help us learn more about them.
19.What do we know about black holes?
A.They are dark holes with a bright center.
B.They are many black circles inside each other.
C.They are black holes with colorful rings in the center.

On Dec. 25, 2021, a new age of space science started when NASA set up the James Webb Space Telescope (望远镜) . It will change our understanding of space.
According to NASA, Webb is the world’s largest and most powerful telescope.The old Hubble Space Telescope mostly sees what we see-light, But Webb sees infrared (红外线的) light, which is invisible to the human eye. It can make new discoveries by examining stars inside those dust clouds. It will be able to“look at’”the first light after the Big Bang (宇宙大爆炸) which created our universe, as well as how young stars grow.
Webb “sees” by using mirrors to collect infrared light from the universe. The bigger the mirror is, the more details it can see. The telescope is as tall as a three-story building and as big as a tennis court. is so big that it has to fold its mirrors to fit inside the rocket, Once in orbit (轨道), they will unfold, creating one large mirror.
The telescope flew 29 days to reach its orbit, which is more than one million kilometers away from the earth. After six months, it sent back its first picture.
The building of the telescope started in 2004. About 40 million hours of work, thousands of scientists from 14 countries, 10 billion dollars and 1 heavy-lift rocket made it all possible.
Now it’s ready to help us answer key questions, such as where we came from and whether we’re alone in the universe.

Gravity, the invisible force that keeps our feet on the ground, is a basic concept in physics. Understanding gravity is important in unlocking the secrets of the universe.
Gravity is a force of attraction that exists between any two objects in the universe. It makes planets go around the sun and creates stars and galaxies (银河系). Gravity is also what gives weight to objects on Earth and keeps us from floating away. It pulls everything towards the center of the Earth, keeping us firmly on the ground.
The strength of gravity depends on two things: how big an object is and how far apart objects are. If something is very big or has a lot of things in it (like the Earth) it has a strong pull of gravity. But if things are far away from each other, the pull of gravity is weaker. That’s why astronauts feel weightless in space because the force of gravity there is much smaller.
Gravity is really important in our everyday lives. It makes things fall down when we drop them and keeps us from floating away when we walk or jump. It also affects the tides, making the ocean water rise and fall. Without gravity, the planets wouldn’t stay in their paths, and life as we know wouldn’t exist either.
Gravity is important not only on Earth, but also as a force that shapes the entire universe. It keeps galaxies well, allowing stars to form and planets to exist. Gravity also influences events in space such as black holes and the bending (弯曲) of light around large objects.
Gravity is a powerful force that controls how things move in space and keeps us on the ground. It affects how objects fall and the rise and fall of the ocean. Therefore, it is essential for our everyday lives.
32.How does the passage bring up the topic?
A.Tell stories. B.Ask questions. C.Give a definition. D.Make a comparison.
33.According to the passage, why do we feel weightless in space?
A.The force of gravity is weaker in space. B.There is no gravity in space.
C.Objects in space have no mass. D.Distance has no effect on gravity in space.
34.Which of the following statements is NOT true according to the passage?
A.The force of gravity is stronger between closer objects.
B.Gravity plays a role in the formation of stars and galaxies.
C.Gravity is only present on Earth as well as on Mars.
D.Gravity is responsible for keeping planets in orbit around the sun.
35.What can we infer from the last paragraph?
A.Gravity is a mysterious force that is not fully understood.
B.Gravity only affects celestial bodies and has little impact on our daily lives.
C.The influence of gravity extends to various aspects of our lives.
D.Gravity is a force that can be ignored in our day- to- day activities.

Scientists have long believed that there is a black hole in the center of our galaxy(星系), the Milky Way. But last Thursday, scientists released the first image(画像) ever of this black hole. The scientists hope the image will help them learn more about black holes and how they work.
All the stars you see in the night sky are part of our galaxy. And in the center of our galaxy is a black hole. It’s called Sagittarius (人马座) A.
A black hole is a place where matter is so dense that the pull of its gravity(引力) is very, very strong. The gravity from a black hole is so strong that even light cannot get away from it.
The scientists actually take a picture of its shadow and the ring of light around the hole called the “event horizon(视界)”. It’s between the hole and the light that is beyond the pull of the hole’s gravity.
The scientists responsible for the picture of the black hole are part of a group called the Event Horizon Telescope project. About 300 scientists in 20 countries have been working on the project for over 12 years.
The telescope the scientists use isn’t really a telescope, but several large radio telescopes around the world. This allows the scientists to later use computers to process the radio signals from the telescopes into a single image.
Sagittarius A is much closer than many other black holes in space, since it’s in our own galaxy. However, it’s changing very rapidly. One scientist described getting a good image of it as “like trying to take a clear picture of a dog quickly chasing its tail”.
The information for the picture of Sagittarius A was collected at the same time. But it took far longer to process the information to create the new image.
Now the scientists have successfully captured the image!
36.What is Sagittarius A according to the passage?
A.All the parts of our galaxy. B.One of the stars in the night sky.
C.The center of our solar system. D.A black hole in our galaxy.
37.What does the underlined word “dense” mean in Chinese?
A.遥远的 B.密集的 C.古老的 D.稀薄的
38.Which of the following is NOT true about the scientists in 20 countries?
A.They took the picture of the black hole directly.
B.It took them a lot of time and effort to get the image.
C.They actually processed lots of radio signals into one image.
D.They have been working on the project for over 12 years.
39.What is the passage mainly talk about?
A.Scientists’ new study about our galaxy. B.Facts about black holes and how they work.
C.First picture of the Milky Way’s black hole. D.Event Horizon Telescope project.
二、完形填空
Recently, great scientists around the world were able to create a real picture of a black hole. The black hole named Powehi is about 55 million light years from Earth. This means light travelling from that point takes 55 million years to be 40 on the Earth. When we look at the picture of Powehi, it’s like we are looking into the past. Light started a journey from Powehi to planet earth millions of years ago, 41 light from the sun takes only about 8 minutes and 20 seconds.
Black holes have always attracted scientists because black hole isn’t a hole. 42 , it is a place in space with a lot of matter (物质) inside. It has so much gravity that our sun can be pulled into it 43 . Even light can’t avoid it. As a result, it’s always black.
It was an amazing discovery. It 44 many ideas about black holes. It also proved Albert Einstein was 45 about his Theory of General Relativity (相对论) which explains the relationship between space and time.
This discovery is more than a story about the development of technology that 46 humans to see a black hole for the first time. It’s also a story of how these scientists from all over the world worked together for many years to have this great 47 .
Scientists also point out that the first picture of Powehi is the 48 of many more discoveries. One of the most important lessons we learn from this picture is to keep learning. Aristotle once said, “The more you know, the more you 49 you don’t know.” You never know what amazing discovery you will find.
40.A.seen B.touched C.covered D.used
41.A.after B.until C.while D.because

Men have won most of the Nobel Prizes in science in the past. But this year, we saw m 50 women winners than before.
Jennifer Doudna from the US and Emmanuelle Charpentier from France shared the Nobel Prize in Chemistry. It’s the first time in history for two women to win the prize without having to share it with a man. At the same time, US astronomer Andrea Ghez t 51 the fourth woman to win a Nobel Prize in Physics. Its first female winner was Marie Curie (居里夫人) in 1903.
When h 52 that they were the sixth and seventh women in history to win the Chemistry Prize, Charpentier said that she hopes girls and young female scientists will “understand that nothing is i 53 .” They can “find great discoveries” no matter what their gender (性别) is.
Ghez who was awarded for her research on black holes, had the same feeling. “I hope to inspire (激励) more young women into the field,” Ghez said. She is also one of the w 54 of the 2006 children’s book You Can Be a Woman Astronomer.

China has just opened its FAST radio telescope (射电望远镜) to international scientists. It means scientists across the world can apply for using the telescope to do astronomical observations.
FAST is short for Five-hundred-meter Aperture Spherical radio Telescope. It was completed in September 2016 and it officially began operating in January 2020. Measuring 500 meters in diameter. FAST is the world’s largest single-dish radio telescope, and is 10 times more sensitive than the 100-meter Radio Telescope Effelsberg in Germany.
The major scientific task of the telescope is the observation of pulsars (脉冲星). The study of pulsars can help to confirm the existence of gravitational radiation (引力辐射) and black holes, and help solve many other major questions in physics. Another major scientific goal of FAST is to search for life outside the Earth.
The telescope is located in a naturally deep and round karst depression (喀斯特洼地) in southwest China’s Guizhou Province. The first advantage of the selected site is the altitude (海拔). The average altitude of Guizhou is about 1,100 meters. Generally, the higher the altitude, the more the telescope can observe. Secondly, the radio telescope needs to have a “big pan” to receive better signals. The huge natural depression could reduce the difficulty of construction. Moreover, the selected site in Guizhou is far away from cities, and has a low population density, which reduces the interference (干扰) caused by wireless devices such as TVs, mobile phones and radios from human activities.
So far, FAST has found over 300 pulsars. Experts predict that the number could reach 1,000 in five years and that the telescope could find and locate the first pulsar outside the Galaxy.
14.Who can use FAST?
A.Chinese scientists. B.Scientists from all countries.
C.Soldiers and policemen. D.All Chinese citizens.
15.When did FAST start working officially?
A.In 2015. B.In 2016. C.In 2020. D.In 2021.
16.What do we know from the fourth paragraph?
A.The advantages of the selected site for FAST.
B.Guizhou Province has the highest altitude in China.
C.The reasons for using mobile phones less.
D.FAST is built in a pan-shape place to keep people out.
17.What do scientists think FAST will probably be able to do in the future?
A.Identify more than 300 pulsars in five years.
B.Discover the first pulsar outside the Galaxy.
C.Locate wireless devices around the world.
D.Collect all kinds of sounds in space.
18.Where can you probably read this passage?
A.Human and Nature B.Geography 101
C.Animals and Plants D.Scientific World

What do black holes look like? Human beings have wanted to know about it for a long time. In 2019, we finally got the answer. They look like dark circles with a bright ring around the outside.
Scientists took the world’s first photo of a black hole. Scientists didn’t use a camera to take the picture. They used eight radio telescopes in different places around the world. Telescopes got signals (信号) from the black hole. Scientists used computers to process (处理) the signals. It took them two years to get the final picture.
The black hole is very far from Earth—about 55 million light years away. One light year is the journey that light travels in one year. One light year is about 9 trillion (万亿) kilometers.
This isn’t the only black hole in the universe. In fact, scientists believe every large galaxy (星系) has a big black hole at its center. The one in our galaxy is called Sagittarius A.
Black holes are some of the most mysterious (神秘的) things in the universe. This photo can help us learn more about them.
19.What do we know about black holes?
A.They are dark holes with a bright center.
B.They are many black circles inside each other.
C.They are black holes with colorful rings in the center.
D.They are dark circles with a bright ring around the outside.

On Dec. 25, 2021, a new age of space science started when NASA set up the James Webb Space Telescope (望远镜) . It will change our understanding of space.
According to NASA, Webb is the world’s largest and most powerful telescope.The old Hubble Space Telescope mostly sees what we see-light, But Webb sees infrared (红外线的) light, which is invisible to the human eye. It can make new discoveries by examining stars inside those dust clouds. It will be able to“look at’”the first light after the Big Bang (宇宙大爆炸) which created our universe, as well as how young stars grow.
Webb “sees” by using mirrors to collect infrared light from the universe. The bigger the mirror is, the more details it can see. The telescope is as tall as a three-story building and as big as a tennis court. is so big that it has to fold its mirrors to fit inside the rocket, Once in orbit (轨道), they will unfold, creating one large mirror.
The telescope flew 29 days to reach its orbit, which is more than one million kilometers away from the earth. After six months, it sent back its first picture.
The building of the telescope started in 2004. About 40 million hours of work, thousands of scientists from 14 countries, 10 billion dollars and 1 heavy-lift rocket made it all possible.
Now it’s ready to help us answer key questions, such as where we came from and whether we’re alone in the universe.

Gravity, the invisible force that keeps our feet on the ground, is a basic concept in physics. Understanding gravity is important in unlocking the secrets of the universe.
Gravity is a force of attraction that exists between any two objects in the universe. It makes planets go around the sun and creates stars and galaxies (银河系). Gravity is also what gives weight to objects on Earth and keeps us from floating away. It pulls everything towards the center of the Earth, keeping us firmly on the ground.
The strength of gravity depends on two things: how big an object is and how far apart objects are. If something is very big or has a lot of things in it (like the Earth) it has a strong pull of gravity. But if things are far away from each other, the pull of gravity is weaker. That’s why astronauts feel weightless in space because the force of gravity there is much smaller.
Gravity is really important in our everyday lives. It makes things fall down when we drop them and keeps us from floating away when we walk or jump. It also affects the tides, making the ocean water rise and fall. Without gravity, the planets wouldn’t stay in their paths, and life as we know wouldn’t exist either.
Gravity is important not only on Earth, but also as a force that shapes the entire universe. It keeps galaxies well, allowing stars to form and planets to exist. Gravity also influences events in space such as black holes and the bending (弯曲) of light around large objects.
Gravity is a powerful force that controls how things move in space and keeps us on the ground. It affects how objects fall and the rise and fall of the ocean. Therefore, it is essential for our everyday lives.
32.How does the passage bring up the topic?
A.Tell stories. B.Ask questions. C.Give a definition. D.Make a comparison.
33.According to the passage, why do we feel weightless in space?
A.The force of gravity is weaker in space. B.There is no gravity in space.
C.Objects in space have no mass. D.Distance has no effect on gravity in space.
34.Which of the following statements is NOT true according to the passage?
A.The force of gravity is stronger between closer objects.
B.Gravity plays a role in the formation of stars and galaxies.
C.Gravity is only present on Earth as well as on Mars.
D.Gravity is responsible for keeping planets in orbit around the sun.
35.What can we infer from the last paragraph?
A.Gravity is a mysterious force that is not fully understood.
B.Gravity only affects celestial bodies and has little impact on our daily lives.
C.The influence of gravity extends to various aspects of our lives.
D.Gravity is a force that can be ignored in our day- to- day activities.

Scientists have long believed that there is a black hole in the center of our galaxy(星系), the Milky Way. But last Thursday, scientists released the first image(画像) ever of this black hole. The scientists hope the image will help them learn more about black holes and how they work.
All the stars you see in the night sky are part of our galaxy. And in the center of our galaxy is a black hole. It’s called Sagittarius (人马座) A.
A black hole is a place where matter is so dense that the pull of its gravity(引力) is very, very strong. The gravity from a black hole is so strong that even light cannot get away from it.
The scientists actually take a picture of its shadow and the ring of light around the hole called the “event horizon(视界)”. It’s between the hole and the light that is beyond the pull of the hole’s gravity.
The scientists responsible for the picture of the black hole are part of a group called the Event Horizon Telescope project. About 300 scientists in 20 countries have been working on the project for over 12 years.
The telescope the scientists use isn’t really a telescope, but several large radio telescopes around the world. This allows the scientists to later use computers to process the radio signals from the telescopes into a single image.
Sagittarius A is much closer than many other black holes in space, since it’s in our own galaxy. However, it’s changing very rapidly. One scientist described getting a good image of it as “like trying to take a clear picture of a dog quickly chasing its tail”.
The information for the picture of Sagittarius A was collected at the same time. But it took far longer to process the information to create the new image.
Now the scientists have successfully captured the image!
36.What is Sagittarius A according to the passage?
A.All the parts of our galaxy. B.One of the stars in the night sky.
C.The center of our solar system. D.A black hole in our galaxy.
37.What does the underlined word “dense” mean in Chinese?
A.遥远的 B.密集的 C.古老的 D.稀薄的
38.Which of the following is NOT true about the scientists in 20 countries?
A.They took the picture of the black hole directly.
B.It took them a lot of time and effort to get the image.
C.They actually processed lots of radio signals into one image.
D.They have been working on the project for over 12 years.
39.What is the passage mainly talk about?
A.Scientists’ new study about our galaxy. B.Facts about black holes and how they work.
C.First picture of the Milky Way’s black hole. D.Event Horizon Telescope project.
二、完形填空
Recently, great scientists around the world were able to create a real picture of a black hole. The black hole named Powehi is about 55 million light years from Earth. This means light travelling from that point takes 55 million years to be 40 on the Earth. When we look at the picture of Powehi, it’s like we are looking into the past. Light started a journey from Powehi to planet earth millions of years ago, 41 light from the sun takes only about 8 minutes and 20 seconds.
Black holes have always attracted scientists because black hole isn’t a hole. 42 , it is a place in space with a lot of matter (物质) inside. It has so much gravity that our sun can be pulled into it 43 . Even light can’t avoid it. As a result, it’s always black.
It was an amazing discovery. It 44 many ideas about black holes. It also proved Albert Einstein was 45 about his Theory of General Relativity (相对论) which explains the relationship between space and time.
This discovery is more than a story about the development of technology that 46 humans to see a black hole for the first time. It’s also a story of how these scientists from all over the world worked together for many years to have this great 47 .
Scientists also point out that the first picture of Powehi is the 48 of many more discoveries. One of the most important lessons we learn from this picture is to keep learning. Aristotle once said, “The more you know, the more you 49 you don’t know.” You never know what amazing discovery you will find.
40.A.seen B.touched C.covered D.used
41.A.after B.until C.while D.because
