Mars is sometimes called the Red Planet because of its colour. There isn't enough oxygen (O2) for people on Mars. A space journey to Mars It is important to visit Mars at the right time because the Earth and Mars are always moving. Sometimes, Mars is closer to the Earth than at other times. Choosing the shortest way is a good idea because the journey will cost less. Why Mars? Mars is the safest planet to travel to because: ●it has a little water; ●it gets enough sunlight to use solar power; ●we can try to walk on it; ●a day on Mars is almost as long as on Earth. Quick facts about Mars Diameter（直径）: 6,779km Moons around it: 2 Length of day: 24 hours and 39 minutes Surface temperature: about -63℃ Humans want to find out if there might be life on other planets and scientists believe that Mars is the best planet for life, besides the Earth. ( )11. Why is Mars the safest planet to travel to? A. Because the Earth and Mars are always moving. B. Because the temperature on Mars is neither high nor low. C. Because there is a lot of oxygen and water on Mars. D. Because it gets enough sunlight to use solar power. D ( )12. How many moons go around Mars? A. 2. B. 20. C. 24. D. 37. ( )13. What do scientists believe according to the text? A. Besides the Earth, Mars is the best planet for life. B. There has already been life on Mars. C. There is a lot of water on Mars for life. D. It is impossible to find life on Mars. A A ( )14. What can we know about Mars from the text? A. It's the fourth planet from the Earth. B. It's the closest planet to the Sun. C.

Experiences. A B As is known to all of us, living in space can be very different from that on Earth. One of the most important differences is that there is little gravity in space. So many people think living things cannot develop well in space. ____▲____ A team of American scientists sent mouse embryos (胚胎) to space in August 2021. Then astronauts let them grow on the space station for four days. Guess what happened? The mouse embryos successfully developed just like they do on Earth! The different environment didn't prevent the development of mouse embryos. The scientists soon shared their study. They clearly pointed out that gravity might not have as much effect on the development of these mouse embryos as they had thought before. When the mouse embryos were sent back to the Earth, the scientists also checked their DNA and genes (基因). They found that they were still the same. However, they still needed to do more studies to make sure everything was okay with the embryos. This surprising research is the first to suggest that mouse embryos can successfully develop in the special environment of space. The team's next plan is to put these embryos into the mice to see if they can give birth. If that goes well, it may not be impossible for us to see space babies in the future! ( )16. Which of the following can be put in “____▲____” in Paragraph 1? A. Some children would like to travel to space. B. Many researchers are trying to solve the problem. C. However, there are also several bad sides about this. D. However, a finding may show they're wrong. D ( )17. What did the American scientists find out? A. There were strange lives in space. B. Mouse embryos could grow in space. C. Many space babies were born in 2021. D. The animals grew faster in space than on Earth. B ( )18. What does the underlined word “prevent” in Paragraph 2 mean? A. Stop. B. Allow. C. Follow. D. Afford. ( )19. What can we learn from Paragraph 3? A. The embryos' DNA didn't change in space. B. Something was wrong with the embryos in space. C. Gravity had a big effect on the embryos' growth. D. The mouse embryos in space shared different genes. A A ( )20. What is the research team's next plan? A. To put the embryos into the mice. B. To send more mouse embryos to space. C. To take some human babies to space. D. To study if mice can give birth in space. A C On 17 December 2024, two Chinese astronauts, Cai Xuzhe and Song Lingdong, made history. They did a spacewalk outside the Tiangong space station and broke a world record. They are part of the three-person team on the Shenzhou-19. The spacewalk started in the afternoon. Cai went out of the space station first at 12：51 p.m. Song followed him about 90 minutes later. After working very hard for hours, they came back to the station at 9：57 p.m. Before this, the longest spacewalk was 8 hours and 56 minutes. American astronauts James Voss and Susan Helms set that record in March 2001. Our Chinese astronauts walked 10 minutes longer! While Cai and Song were outside, Wang Haoze stayed inside the space station. She made sure everything worked well. The three astronauts worked together. They also got help from the space station's robot arm and the scientists on Earth. Cai and Song did many important things during the spacewalk. They checked tools and put in a machine to protect the space station from space junk. Their work was a big success! This spacewalk is the 17th time Chinese astronauts have worked outside the Tiangong space station. These brave astronauts' hard work is good for China and the whole world. They are heroes. Their work shows us that everything is possible if we try hard. Their success tells us to dream big! ( )21. How many people were there on the Shenzhou-19? A. Two. B. Three. C. Four. D. Five. ( )22.

She stayed inside the space station and made sure everything worked well. D ( )24. How many times had Chinese astronauts worked outside the Tiangong space station before this spacewalk? A. 16 times. B. 17 times. C. 18 times. D. 19 times. ( )25. What can we learn from these astronauts' work? A. Space work is very easy. B. Only astronauts can dream big. C. Everything is possible if we try hard. D.
