However, when he left home for college, he was able for the first time to start taking his life and weight into his own hands.He started by shopping at a local farmers market, an experience that inspired him profoundly. The idea that a farmers market represents local, sustainable, healthy food with a human connection where you can interact with the people that grow your produce was extremely appealing to him, and he began to think about the food that people at his university were eating. From what he saw at farmers markets, Hai realized that dining hall food was not “rear” food A lot of it is frozen or processed, and has unhealthy additives. His ideas continued to develop as he started taking classes about food sustainability at university, and after the summer of 2014 during which he cooperated with other students9 he launched into his senior year at the University of California full force with the Real Food Challenge (RFC) campaign, a project he co-founded that aims to reinvest university spending in food that is “real”: ecologically-sound, community-based, humane, and fair; as opposed to those traditional purchases with those unhealthy additives and processed products.Not only has Hai started a movement of change across the university dining system, but he has also grown extremely as an individual，now with strong leadership abilities and great vision. In addition, after he started learning about food sustainability and taking action at university, Hai has lost over 100 pounds, and has been able to start enjoying activities such as backpacking and swimming that were not a possibility for him previously. He is confident instead of distraught now.5. When did Hai get the idea of “rear” food?A. When purchasing the locally-made foodB. When reforming the university dining system.C. When reinvesting university spending in food.D. When organizing the Real Food Challenge campaign.6. What benefit has the campaign brought to Hais occupational development?A. He has been hired by the university. B. He has become an expert in food fieldC. He has got excellent leading ability. D. He has become much thinner than before.7. According to Hai, “real” food is .A. rich in nutrition B. made by expertsC. frozen or processed D. healthy without additivesCScientists have found living organisms trapped in crystals (晶体) that could be 50,000 years old.The organisms were found in a hot, but beautiful cave system in Naica, Mexico. These ancient life forms can be seen only with a microscope. Penelope Boston, who leads the Astrobiology Institute at NASA, the space agency of the United States, says the ancient microbes were able to live by eating minerals such as iron.She spoke about the discovery recently at a meeting of the American Association for the Advancement of Science. If the findings are confirmed, they will show how microbes can survive in extreme conditions. Forty different kinds of microbes and some viruses were found in the underground area. The genetic structures of these organisms are 10 percent different from those of their nearest relatives.The caves in Naica are 800 kilometers deep. They were once used for mining lead. Before the miners began working in the caves, the area was separated from the surface and the outside world. Some of the caves are as big as the large religious centers built during Europes Middle Ages. There are crystals covering the walls. The caves are so hot that scientists must wear special clothing to keep cool. The clothing keeps the crystals safe from human germs (病菌) or other damage. Boston said the researchers could only work for about 20 minutes at a time before they had to go to a room that was 38 degrees Celsius to cool down.NASA officials would not let Boston share her findings with scientific experts before last weeks announcement. So scientists could not say much about the findings. But Norine Noonan, a biologist with the University of South Florida, said she believed them. “Why are we surprised?” Noonan asked. “ As a biologist, I would say life on Earth is extremely tough and extremely colorful.”Boston is also studying microbes commonly found inside caves in other countries, such as Ukraine and the United States. These microbes appear to be impossible to kill. Boston said they show how difficult life on Earth can be.8. The existence of the ancient microbes relies on _.A. surrounding insects B. eating mineralsC. diverse plants D. absorbing air9. What can we infer about the eaves in Naica from the passage?A. The temperature in the caves is quite low.B. The environment in the caves is difficult to adapt to.C. The walls are covered by crystals.D. The caves have been explored since they were formed.10. What is the biologist Norine Noonans attitude towards the findings?A. Neutral. B. Doubtful.C. Positive. D. Indifferent.11. Whats the main idea of the passage?A. Living organisms bring hope to scientific research.B. Caves provide living environment for living organisms.C. Microbes show great power to survive in terrible conditions.D. Scientists Discover 50,000-year-old “super life” in Mexico.DIts true that quite a few most respected scientific authorities have confirmed that the world is becoming hotter and hotter. Theres also strong evidence that humans are contributing to the warming. Countless recent reports have proved the same thing. For instance, a 2010 summary about the climate science by the Royal Society noted that: The global warming over the last half - century has been caused mainly by human activity.”You may not believe that humans could change the planets climate, but the basic science is well understood. Each year, billions of tons of greenhouse gases are released into the atmosphere because of human activity. As has been known for years, these gases hold heat that would otherwise escape to space, wrapping the planet in an invisible blanket.Of course, the earths climate has always been changing due to “natural” factors such as volcanic eruption or changes in solar, or cycles concerning the Earths going around the sun. According to the scientific research, however, the warming observed by now matches the pattern of warming we would expect from a build - up of greenhouse gas in the atmosphere - not the warming we would expect from other possible causes.Even if scientists did discover another reasonable explanation for the warming recorded so far, that would give birth to a difficult question. As Robert Henson puts it: “If some newly discovered factor is to blame for the climate change, then why arent carbon dioxide and the other greenhouse gases producing the warming that basic physics tells us they should be?”The only way to prove with 100% certainty that humans are responsible for global warming would be to run an experiment with two identical Earths-one with human influence and one without. That obviously isnt possible, and so most scientists are careful not to state human influence as an absolute certainty.12. The text is developed by _.A. giving typical examples B. following the order of spaceC. comparing and finding difference D. analyzing a theory and arguing it13. Which of the following is not the cause of climate change?A. volcanic eruption B. floods arid droughtsC. changes in solar D. cycles concerning the Earths going around the sun14. The underline word identical” in the last paragraph probably means _.A. exactly the same B. totally differentC. extremely important D. partly independent15. Which of the following can be the best title?A. Are Humans Definitely Causing Global Warming?B. Are All the Scientists Really Scientific?C. Where Is Global Warming Leading Us to?D. Whats the Relation of Global Warming and Greenhouse Gases?第二节 （共 5 小题，每小题 2 分，满分 10 分） 根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。 How to escape from a car in water“If you get on your phone and call your parents or your sister, or 911,you will die, " says Robert May, a 21-year-old veteran （老兵）of the Indiana State.
