1、高三晚自习限时练习练习时间：3月24日晚；使用群体：重点班一、阅读理解APeople are always curious about the secret of polyglots people who speak a lot of languages about how they make it. So, I decided to meet some polyglots and find that out.Benny, from Ireland, told me that his method is to start speaking from day one. He learns a f
2、ew phrases and goes to meet native speakers and starts having conversations with them right away. He doesnt mind making even 200 mistakes a day, because thats how he learns.Lucas, from Brazil, had a really interesting method to learn Russian. He simply added Russian speakers as new friends online, a
3、nd then opened a chat window with one of them and wrote “Hi” in Russian. And the person replied, “Hi, how are you?” Lucas copied this and put it into a text window with another person, and the person replied, “Im fine, thank you. How are you?”Lucas copied this back to the first person, and in this w
4、ay, he had two strangers have a conversation with each other without knowing about it.I met polyglots who always start by imitating(模仿) sounds of the language and others who always learn the 500 most common words of the language, and still others who always start by reading about the grammar. If I a
5、sked a hundred different polyglots, I heard a hundred different methods of learning languages.As I was listening to these polyglots telling me about their methods, I suddenly realized that the one thing they all have in common is that they simply found ways to enjoy the language-learning process(过程)
6、. All of these polyglots were talking about language learning as if it was great fun. So, if youve also tried to learn a language and you gave up, thinking its too difficult or you dont have the language talent(天赋), give it another try. Maybe youre also just one fun method away from learning that la

10、ll, but these invasive fish are a threat. Outside of their range, they defeat other freshwater creatures, like fishes and tadpoles, and feast on their eggs. Since they have few natural predators (捕食者), their population goes unchecked as they cause damage to native wildlife. Fortunately, scientists h
11、ave now invented a new tool meant to intimidate mosquitofish: a robotic fish. “Instead of killing them one by one, were presenting an approach that can inform better strategies to control them,” said Giovanni Polverino, a biologist at the University of Western Australia. “We made their worst nightma
12、re become real: a robot that scares the mosquitofish but not the other animals around it.”The robot, which resembles a largemouth bass, one of the mosquitofishs natural predators, was equipped with a camera to recognize mosquitofish and tadpoles. The researchers set up 12 tanks with six mosquitofish
13、 and six tadpoles in each one and allowed the creatures to adapt for a week before meeting the robot. For one hour twice a week for five weeks, each group was placed in a tank with the robot. In the robotic fishs presence, the mosquitofish spent more time getting together, and their swimming became
14、more unstable. With the mosquitofish anxious and scared, the tadpoles ventured out more. These effects even lasted for weeks after the final meet with the robot. When the creatures returned to their tanks, the mosquitofish swam at a lower speed and didnt eat as much, which are signs of anxiety. No c
15、hange, on the other hand, can be detected on tadpoles. Whats more, the mosquitofish spent so much energy living in terror that they lost weight. Males body shapes also changed to become more streamlined, likely so they can escape more quickly when theyre scared. Though the study showed promising res
16、ults, these robots cant be released into the water yet. The team still needs to understand the long-term impacts on other wildlife and downstream effects on the ecosystem as a whole. But Polverino says they achieved their main goal: to prove fear can affect the survival of mosquitofish.；5. What does
17、 the underlined word “intimidate” mean in paragraph 2?APoison.BAttract.CFrighten.DRecognize.；6. How did the researchers carry out the experiment?ABy comparing behaviors of two species.BBy interviewing the inventor of the robot.CBy collecting data from previous studies.DBy observing the life cycle of
18、 mosquitofish.；7. What was the change of the mosquitofish?AThey became stronger.BThey were less active.CThey started attacking easily.DThey showed little change.；8. What is Polverinos attitude towards the robotic fish?AApproving.BDisappointed.CObjective.DSkeptical.CCorals are made up of hundreds of
19、thousands of small organisms (微生物). For the past five years, researchers in Hawaii and Australia have been engineering corals inside a lab to see if they could better resist the effects of climate change. The team tested three methods for making corals that would be strong and healthy in nature. One
20、 is selective breeding (繁殖), aiming to produce babies with desirable characteristics. The second method subjected the corals to increasing temperatures to condition them to be able to survive in warm ocean environments. The third involved making changes to the algae (海藻) that provide corals with nec
21、essary nutrients. The leader of the project, Kira Hughes, said all the methods proved successful in the lab. She said some scientists might worry that such methods go against the natural processes of nature. But with the planet continuing to get warmer and warmer, she does not see any better options
22、. “We have to intervene (干预) in order to make a change for coral reefs to survive into the future,” Hughes said. When ocean temperatures rise, corals turn white, a process called bleaching. When this happens, corals can quickly become sick and die. But for years, scientists have been observing coral
23、s that have survived bleaching. They are now centering on those healthy survivors. Those corals were used as the parents for the newly created kinds. A recent study found bleaching to be the biggest current threat to the worlds coral reefs. Between 2009 and 2018, the world lost about 14 percent of i
24、ts corals. “Corals are threatened worldwide by a lot of things, but increasing temperatures are probably the most serious,” said Crawford Drury. He is the chief scientist at Hawaiis Coral Resilience Lab. Madeleine van Oppen, a research scientist, told the AP there were concerns about whether the exp
25、eriments could result in a loss of genetic diversity. And there were critics who said the scientists were “playing god” by making such changes to the reef. “Well, you know, humans have already intervened in the reef for a very long period of time,” van Oppen said. “Rather than editing genes or creat
26、ing anything unnatural, the researchers are just attempting to repair the damage,” van Oppen added.9. What is Kira Hughes opinion on engineering corals inside a lab?AIt is quite unnecessary.BIt is the best choice so far.CIt has a slim chance of success.DIt follows the natural processes.10. What does
27、 Crawford Drury agree with?AThe sickness of algae is the root of corals death.BBleaching is the only threat to the worlds coral reefs.CRising ocean temperatures are seriously affecting corals.DNo corals can survive when ocean temperatures increase.11. What is Madeleine van Oppens attitude towards pe

Zhai Zhigang, Wang Yaping, and Ye Guangfu delivered the lectu
30、re and it was no ordinary course. 13 A total of 1,420 students attended the lecture from five classrooms across China.Assisted by the other two crew members, Wang first gave a tour around, telling students how they go about their lives and work on the space station. She showed them the microwave, wa
31、ter machine and refrigerator in the space kitchen. 14 Wang said the water they drink is recycled, noting that there is no difference in taste between regular and recycled water.Wang said the astronauts may look a little fat and swollen as the microgravity in space can affect blood circulation. 15 Sh

In
33、 a buoyancy (浮力) experiment, Wang put a table tennis ball in a glass of water. 16 However, it remained in the middle of the water. Buoyancy almost disappeared in the weightless environment.At the end of the 60-minute class, the three astronauts tried to satisfy students curiosity through a real-time
34、 question and answer session. How do oxygen and carbon dioxide recycle on the space station? Do stars still twinkle in space? 17 “ The secrets of space and science are boundless, and the future is yours,” said Zhai, commander of the Shenzhou-13 mission.AIt didnt float to the surface like on Earth.BI

Obviously he couldnt climb up and down easily like other squirrels. He moved down, carefully holding onto the tree. “Be 23 ,” I thought, ch
