With it, people didn’t have to remember everything in their heads. They could communicate with people they never saw and share their knowledge with others. Later, the Greeks invented books with lots of pages to replace scrolls (卷轴).
For more than a thousand years, the pages of books were made from animal 2 . That changed in the thirteenth century. The Chinese invented the 3 of making paper. After that, Johannes Gutenberg invented the printing press. Before that, books in Europe were copied by hand, so they were very expensive. The invention of the printing press made it possible for more people to 4 books. But human invention does not stop. Every year, more stories are bought as e-books and read on a screen.

Passage 1
Here’s how to make a model submarine (潜水艇) that dives (潜水) and comes up from underwater like a real one.
You’ll need
●Plastic bottle ●Tape (胶带) ●Thin rubber (橡胶的) or plastic tube (管子)
●Waterproof (防水的) modeling clay (黏土)—not real clay, which dissolves (溶解) in water
●Small scissors ●Bathtub (浴盆)
(1) Cut two small holes on one side of the bottle. Tape coins to that side of the bottle. Remove (摘下) cap, seal (密封) the tube to the bottle with clay.
(2) Fill tub with water; put bottle in and let it fill with water.
(3) Gently blow into the tube and observe (观察) what happens.
Stop blowing and close the tube with your thumb (大拇指).
Lift your thumb and watch what happens.
What happened?
When you blow, air pushes out water, the bottle becomes lighter and rises.
Bottle sinks (下沉) when it fills with water and coins weigh it down.
Coins keep holes pointing downward, so air does not escape.
When you stop blowing and seal (密封) the tube with your thumb, the bottle floats.
Lift your thumb, air escapes (逸出) through the tube and the bottle sinks (下沉).
A real submarine works this way, by filling tanks with air or water.

三、语法选择
Passage 1
阅读下面短文,掌握其大意,根据语法和上下文连贯的要求,从每题所给的三个选项中选出一个最佳答案,并将答题卡上对应题目所选的选项涂黑。
Albert Einstein once said, “I have no special talents. I am only passionately curious.” The 1 inventions in history would be impossible without curiosity.
Curiosity can bring new discoveries. Benjamin Franklin is 2 great example. He was drawn to electricity and had a deep curiosity about its nature. He did lots of research to try to understand it. For example, he flew a kite 3 a storm. His curiosity led him to invent the lightning rod. Since then, this simple rod 4 thousands of buildings from lightning fires.
Curiosity can also make people brave. Just look at Wan Hu, the Ming Dynasty pioneer of space exploration. He was so curious about space that he invented a “flying chair”! He lost 5 life while testing this invention. 6 he failed, his dream has given ideas to many modern rocket scientists.
But curiosity is more than just taking risks. It also drives people toward certain 7 . Zhang Heng, a Chinese scientist and 8 , was curious about the world: how did everything in the world move? Night after night he was watching the stars while others 9 . Finally, he drew China’s first star map and invented the first earthquake detector. His curiosity continues 10 scientists today.
As Jacques Cousteau said, “What is a scientist after all? It is a curious man looking through a keyhole, the keyhole of nature, trying to know what’s going on.” Curiosity is the key. It opens one door after another for us to discover a new world.

【导语】本文以爱因斯坦的话开篇,借富兰克林、万户、张衡的事例,说明好奇心是发明创造的关键,推动探索与进步。
1.句意:没有好奇心,历史上最伟大的发明就不可能存在。
great极好的,形容词;greater更好的,形容词的比较级;greatest最好的,形容词的最高级。根据“in history”可知,此处表示多者以上范围最突出的事,所以使用最高级。故选C。
2.句意:本杰明·富兰克林就是一个很好的例子。
a一个,用于辅音音素前;an一个,用于元音音素前;the这/那,定冠词。根据“Benjamin Franklin is...great example.”可知,本杰明·富兰克林就是“一个”很好的例子。great以辅音音素/ɡ/开头,所以使用a。故选A。
3.句意:他在暴风雨中放风筝。
at在(某处/时刻);opposite在……对面;during在……期间。根据“he flew a kite...a storm.”可知,他“在”暴风雨“期间”放风筝。故选C。

Passage 2
Last month, a major scientific discovery in artificial intelligence 1 the National Innovation Prize. The invention—an intelligent learning system—didn’t happen 2 accident. A research team worked hard for over five years before they finally succeeded.
This system is designed to help students learn more efficiently. It can process 3 pieces of learning information and spread much knowledge in a more vivid and understandable way. For example, it uses virtual reality to 4 students to “travel” inside a cell or “walk” on Mars. Teachers can use it to make 5 easier to explain difficult concepts.
What’s more, the system encourages students to learn by themselves. They can imagine 6 their own science projects or doing experiments in a simulated lab. It offers 7 every day—maybe a challenging maths game or an interesting historical story.
8 encouraging it is to see technology changing education! This system is even 9 than we thought. It hardly leaves any student behind—whether they learn fast 10 need more time.
We’re living in a wonderful time full of creativity and discoveries. Maybe one day, you will also create something important that helps people around the world!

1.句意:上个月,一项人工智能领域的重大科学发现被授予国家创新奖。
awarded过去式和过去分词;is awarded一般现在时的被动语态;was awarded一般过去时的被动语态。根据“Last month”可知,时态是一般过去时;主语“a major scientific discovery”是动词的承受者,应用被动语态,所以此处应用一般过去时的被动语态。故选C。
2.句意:这项发明 ——一个智能学习系统——并非偶然出现。
in在……里面;by通过;on在……上面。by accident意为“偶然地”,为固定搭配。故选B。
3.句意:它能处理成千上万条学习信息,并以更生动易懂的方式传播大量知识。
thousands of成千上万的;thousand of错误表达;several thousands of错误表达。当thousand与of连用时,需用复数形式,thousands of表示模糊概念,其前不能加several。故选A。
4.句意:例如,它使用虚拟现实让学生在细胞内“旅行”或在火星上“行走”。
allow允许;make使、让;let让。根据空格后的“students to ‘travel’”可知,此处应用allow sb. to do sth.表示“允许某人做某事”,而make和let后接sb. do sth.结构。故选A。
5.句意:老师们可以用它让讲解难懂的概念变得更容易。
that那个;it它;this这个。根据“Teachers can use it to make...easier to explain difficult concepts.”可知,空格处应选it作形式宾语,真正的宾语是动词不定式to explain difficult concepts。故选B。
6.句意:他们可以想象设计自己的科学项目,或在模拟实验室里做实验。
design动词原形;to design动词不定式;designing现在分词和动名词。imagine doing sth.意为“想象做某事”,为固定搭配。故选C。
7.句意:它每天都会提供一些令人兴奋的内容——也许是一个有挑战性的数学游戏,或是一个有趣的历史故事。
something exciting令人兴奋的事情;exciting something错误表达;anything exciting任何令人兴奋的事情。something和anything都是复合不定代词,修饰成分需置于其后,所以选项B错误;something常用于肯定句,anything常用于否定句和疑问句,根据“It offers...every day”可知,这是一个肯定句,所以something exciting符合语境。故选A。
8.句意:看到科技改变教育,这是多么鼓舞人心啊!
What引导感叹句时,修饰名词;How引导感叹句时,修饰形容词和副词;What an引导感叹句时,修饰单数可数名词。根据空格后的“encouraging it is to see technology changing education!”可知,此感叹句的中心词是形容词encouraging,应用How引导此感叹句。故选B。
9.句意:这个系统甚至比我们想象的更强大。
powerful形容词原级;more powerful形容词比较级;much powerful错误表达(much通常不修饰形容词原级)。根据空格后的“than”可知,空格处应用比较级。故选B。
10.句意:它几乎不让任何一个学生掉队——无论他们学得快还是需要更多时间。
and和;so所以;or或、还是。whether...or...意为“无论……还是……”,为固定搭配,用于连接两种相反或不同的情况。故选C。
四、完形填空
Passage 1
Have you ever wanted to send a message to your future self? Or let people 50 years from now know what your life is like today? There’s a fun way to do this—it’s called a “time capsule”! People often 1 small groups of things or information and put them in a safe place.
One of the earliest time capsules was the Detroit (底特律) Century Box. On December 31, 1900, the city put several photos and letters in a box. The box wasn’t opened 2 people took it out on December 31, 2000. The things inside the capsule gave us a look at Detroit in the past.
There were photos of people and places, as well as letters written by local people. Some of them also made 3 predictions for the future. For example, one person predicted that Detroit would have a population of 4 million by 2000. But 4 , the population of the city was 951,000 that year. Humans have 5 sent time capsules into space! The US sent two capsules into space on the Voyager spacecraft in 1977. They’re called the Voyager Golden Records. They contain 6 and pictures that show human life and culture. For example, they have music by classical musician Beethoven and pictures of plants, insects and landscapes. The Voyager spacecraft has traveled far away from our solar system.
It is hoped that aliens (外星人) might find the time capsules someday and learn about humans.

2.句意:这个盒子直到2000年12月31日人们把它拿出来才被打开。
until直到;when当……时;after在……后;since自从。根据“The box wasn’t opened... people took it out on December 31, 2000.”可知,盒子到2000年才被打开,“not...until”是固定搭配,意为“直到……才”,故选A。
3.句意:有些人还对未来做了令人惊讶的预测。
rare稀有的;ordinary普通的;surprising令人惊讶的;right正确的。后文提到“For example, one person predicted that Detroit would have a population of 4 million by 2000... the population of the city was 951,000 that year.”,这种偏差较大的预测是“令人惊讶的”,故选C。
4.句意:但事实上,那一年这座城市的人口是951000。
in fact事实上;at first起初;in total总共;at last最后。根据“For example, one person predicted that Detroit would have a population of 4 million by 2000... the population of the city was 951,000 that year.”,可知前文是“预测”,此处是实际情况,用“in fact”衔接预测与现实的差异,故选A。
5.句意:人类甚至把时间胶囊送入太空!
never从不;even甚至;hardly几乎不;seldom很少。根据“The US sent two capsules into space on the Voyager spacecraft in 1977.”可知是把时间胶囊送入了太空。此处是从“地面时间胶囊”到“太空时间胶囊”的递进,用“even”强调行为的延伸,故选B。
6.句意:它们包含展示人类生活和文化的声音和图片。
letters信件;movies电影;books书籍;sounds声音。后文提到“they have music by classical musician Beethoven”,音乐属于“声音”范畴,故选D。
Passage 2
Choose the best answer and complete the passage (选择最恰当的选项完成短文)
Have you ever heard that some of the world’s most important discoveries happen by accident? The story of penicillin (青霉素) is one such example. This life-saving 1 was discovered through a lucky accident by a scientist named Alexander Fleming.
In September 1928, Fleming was working in his laboratory in London. He was studying staphylococcus bacteria (葡萄球菌),which can cause serious 2 in people. They felt weak. Before leaving for a vacation, he left some polluted dishes with bacteria in his lab by chance. When he returned, he noticed something 3 . A blue-green mold (青绿霉菌) had grown on one dish, and around it was a clear circle where all the bacteria had died.
Instead of throwing away the polluted dish, Fleming became very 4 . He thought the blue-green mold might produce something that could kill bacteria. He decided to test this idea by doing more experiments. He found that the mold juice was indeed very effective at 5 harmful bacteria. He named this amazing mold “penicillin”.
What made penicillin so special was that it could kill bacteria without harming human cells. This meant it could be used safely to treat sick people. Fleming’s discovery opened a new chapter in medicine-the age of antibiotics (抗生素). It completely changed how doctors treat bacteria and has 6 countless lives around the world.
This wonderful story teaches us that in science, keeping an open mind and being curious can sometimes lead to amazing discoveries that change the world.

Passage 2
Nowadays, we have kinds of technologies to protect us from different disasters. We even know where and when some disasters, like the typhoon and the flood, will hit. While most of the new technologies are far away from us, some around us can help people in disasters.
The drone (无人机) is one of them. It can be used to send food and water when a natural disaster happens. Very often the buildings are too dangerous for rescue teams to get in. They can make the drones fly into the buildings to search for those who are still alive first. The drones are also a useful tool for firemen, helping them find and fight wildfires. In some faraway places, drones are the fastest way to send medicine to people in need.
Social media is also a useful tool when it comes to natural disasters. With it, people can know about the natural disasters before they hit. And some social media platforms allow people to mark themselves as safe after disasters, so others can know their situations.
Social media is also a place for up—to—date (最新的) news, so people can learn what is going on in the disaster areas. Besides, many social media platforms allow people to raise money for those in disaster areas. The money will help them get back to normal life as soon as possible. For example, livestreaming (直播) is one of the most popular social media platforms. It helped raise a lot of money for Henan after the flood in 2021.
These technologies can help when there is a natural disaster, but we still need to prepare necessary tools and learn important skills to protect ourselves.

Curiosity can bring new discoveries. Benjamin Franklin is 2 great example. He was drawn to electricity and had a deep curiosity about its nature. He did lots of research to try to understand it. For example, he flew a kite 3 a storm. His curiosity led him to invent the lightning rod. Since then, this simple rod 4 thousands of buildings from lightning fires.
Curiosity can also make people brave. Just look at Wan Hu, the Ming Dynasty pioneer of space exploration. He was so curious about space that he invented a “flying chair”! He lost 5 life while testing this invention. 6 he failed, his dream has given ideas to many modern rocket scientists.
But curiosity is more than just taking risks. It also drives people toward certain 7 . Zhang Heng, a Chinese scientist and 8 , was curious about the world: how did everything in the world move? Night after night he was watching the stars while others 9 . Finally, he drew China’s first star map and invented the first earthquake detector. His curiosity continues 10 scientists today.
As Jacques Cousteau said, “What is a scientist after all? It is a curious man looking through a keyhole, the keyhole of nature, trying to know what’s going on.” Curiosity is the key. It opens one door after another for us to discover a new world.

One of the earliest time capsules was the Detroit (底特律) Century Box. On December 31, 1900, the city put several photos and letters in a box. The box wasn’t opened 2 people took it out on December 31, 2000. The things inside the capsule gave us a look at Detroit in the past.
There were photos of people and places, as well as letters written by local people. Some of them also made 3 predictions for the future. For example, one person predicted that Detroit would have a population of 4 million by 2000. But 4 , the population of the city was 951,000 that year. Humans have 5 sent time capsules into space! The US sent two capsules into space on the Voyager spacecraft in 1977. They’re called the Voyager Golden Records. They contain 6 and pictures that show human life and culture. For example, they have music by classical musician Beethoven and pictures of plants, insects and landscapes. The Voyager spacecraft has traveled far away from our solar system.

Have you ever heard that some of the world’s most important discoveries happen by accident? The story of penicillin (青霉素) is one such example. This life-saving 1 was discovered through a lucky accident by a scientist named Alexander Fleming.
In September 1928, Fleming was working in his laboratory in London. He was studying staphylococcus bacteria (葡萄球菌),which can cause serious 2 in people. They felt weak. Before leaving for a vacation, he left some polluted dishes with bacteria in his lab by chance. When he returned, he noticed something 3 . A blue-green mold (青绿霉菌) had grown on one dish, and around it was a clear circle where all the bacteria had died.
Instead of throwing away the polluted dish, Fleming became very 4 . He thought the blue-green mold might produce something that could kill bacteria. He decided to test this idea by doing more experiments. He found that the mold juice was indeed very effective at 5 harmful bacteria. He named this amazing mold “penicillin”.
What made penicillin so special was that it could kill bacteria without harming human cells. This meant it could be used safely to treat sick people. Fleming’s discovery opened a new chapter in medicine-the age of antibiotics (抗生素). It completely changed how doctors treat bacteria and has 6 countless lives around the world.
This wonderful story teaches us that in science, keeping an open mind and being curious can sometimes lead to amazing discoveries that change the world.

Nowadays, we have kinds of technologies to protect us from different disasters. We even know where and when some disasters, like the typhoon and the flood, will hit. While most of the new technologies are far away from us, some around us can help people in disasters.
The drone (无人机) is one of them. It can be used to send food and water when a natural disaster happens. Very often the buildings are too dangerous for rescue teams to get in. They can make the drones fly into the buildings to search for those who are still alive first. The drones are also a useful tool for firemen, helping them find and fight wildfires. In some faraway places, drones are the fastest way to send medicine to people in need.
Social media is also a useful tool when it comes to natural disasters. With it, people can know about the natural disasters before they hit. And some social media platforms allow people to mark themselves as safe after disasters, so others can know their situations.
Social media is also a place for up—to—date (最新的) news, so people can learn what is going on in the disaster areas. Besides, many social media platforms allow people to raise money for those in disaster areas. The money will help them get back to normal life as soon as possible. For example, livestreaming (直播) is one of the most popular social media platforms. It helped raise a lot of money for Henan after the flood in 2021.
These technologies can help when there is a natural disaster, but we still need to prepare necessary tools and learn important skills to protect ourselves.
