Several ycars ago, Jason Box, a scientist from Ohio, flew 31 giant rolls of white plastic to a glacier (冰川) in Greenland. He and his team spread them across 10,000 feet of ice, then left. His idea was that the white blanket would reflect back the rays of the sun, keeping the ice cool below. When he came back to check the results, he found it worked. Exposed ice had melted faster than covered ice. He had not only saved two feet of glacier in a short time. No coal plants (火电厂) were shut down,no jobs were lost, and nobody was taxed or fired. Just the sort of fix we’re looking for.
“Thank you, but no thank you.” says Ralph King, a climate scientist. He told Grey Childs, an author and commentator, that people think technology can save the planet, but there are other things we need to deal with, like consumption. They burned $50,000 just for the helicopter to bring the plastic to the glacier. This experiment, quote-unquote, gives people false hope that climate change can be fixed without changing human behavior. It can’t. Technology won’t give us a free ride.
Individuals respond to climate change differently. Climatologist Kelly Smith is hardly alone in her prediction that someday soon we won’t be climate victims (受害者)，we will be climate Choosers. More scientists agree with her that if the human race survives. The engineers will get smarter, the tools will get better, and one day we will control the climate. But that then “Just the mention of us controlling the climate sent a small shiver down my back.’’ Grey writes. “Something sounded wrong about stopping ice by our own will.” he says.
Me I like it better when the earth takes care of itself, I guess one day we will have to run the place, but for the moment, sitting at my desk, looking out at the trees bending wildly and the wind howling, I’m happy not to be in charge.；
4. Why does the author mention Jason Box’s experiment in the first paragraph
A．To introduce a possible solution to climate change.
B．To describe a misleading attempt to fix the climate.
C．To report on a successful experiment on saving the glacier.
D．To arouse people’s attention to the problem of global warming.；
5. Which statement would Ralph King most probably agree with
A．The experiment against climate change will not succeed.
B．Technology is not the final solution, let alone its high cost.
C．It’s best to deal with climate change without changing our behavior.
D．Jason’s experiment plays a significant role in fixing climate change.；
6. Which of the following words has the similar meaning to the underlined word in Paragraph 3
A．approval
B．urge
C．shudder.
D．submission.；
7. Which of the following is a suitable title for the text
A．But should we fix the climate
B．Is climate change a real problem
C．How can we take care of the earth
D．What if all the glaciers disappeared
C
In large population studies, people who eat lots of fruits and vegetables high in vitamin C appear to have a reduced risk for various types of cancer, including cancers of the mouth and lung. But it’s not clear that these benefits come specifically from vitamin C．The Age-Related Eye Disease Study found that a daily supplement containing 500 mg of vitamin C can help slow the progress of macular degeneration, an age-related eye disease that causes vision loss. But we don’t know what benefits, if any, are provided by vitamin C in particular.
Many people take vitamin C supplements in unnecessarily high doses to prevent or treat various conditions for which its effectiveness is unproved. The vitamin C supplements have variously been said for staving off sunburn and improving the appearance of wrinkles. None of these benefits have been confirmed in scientific studies.
Perhaps the best-known and most widely promoted use of high-dose(高剂量)vitamin C is to prevent or treat the common cold. Most of the evidence shows that high-dose vitamin C will, at most, shorten a cold by one day. In ordinary circumstances, vitamin C has no preventive value, although a few studies have reported a 50% reduced risk of developing colds among people taking vitamin C in extreme circumstances-for example, skiers, marathon runners, and soldiers working in extreme conditions.
The recommended vitamin C dosage per day for healthy women is 75 mg per day. For adults, the highest safe daily intake is likely to be 2, 000 mg per day. Vitamin C is water-soluble, so any amount more than you need will not be stored in the body. It’s safe in almost any amount from foods, and supplements in recommended amounts are also regarded as safe for most people. In some people, high doses-more than, say, 2, 000 or 3, 000 mg per day-can cause a variety of symptoms. People with kidney conditions should take no more than 1, 000 mg a day.；
8. What can we learn about vitamin C in the first paragraph
A．It can be of better effect in higher doses.
B．It can be a cure for age-related eye disease.
C．It can help slow the progress of some illness.
D．It can reduce the risks of the mouth cancer.；
9. What function does vitamin C have intreating the common cold
A．It can help people save plenty of money.
B．It can stop soldiers from catching a cold.
C．It may reduce a cold by one day at most.
D．It may prevent the common cold efficiently.；
10. How much Vitamin C are healthy women advised to take per day
A．75 mg.
B．500 mg.
C．2, 000 mg.
D．3, 000mg.；
11. Where is this text probably taken from
A．An exam paper.
B．A travel journal.
C．An art guidebook.
D．A science magazine.
二、七选五阅读
Walk Out of the Comfort Zone and Try New Things
For most high school students, free periods (课，节) are useless. From what I have seen, few do homework. 12 . This makes it impossible for those who actually want to do work to complete any. As a senior next year, I think extra periods should be used to take optional subjects.
13 . Now is the time for us students to choose a suitable one. We will experiment in different fields of study. We will never know if we are interested or talented in a subject if we don’t try it.
In my 8th grade, I was told that I had to take an art class as a graduation requirement; so in the 9th grade I took Studio and Art. One of the projects was to build a clay pot, but I built mine incorrectly, so it broke in the kiln (窑). 14 . Now I know for sure that I do not want to be an artist. However, the class was one of my favorites that year. I was able to try new activities and test my ability.
15 ! College is when we should focus on a specific major, but high school is when we have to figure it out.
Half of all college students change their major at some point. By doing that hundreds of dollars are wasted on classes that they would have never needed to take. So use our extra periods to find out what we want to do in college. 16 .
【选项】
B．We should find out what we are good at
C．I’ve avoided anything related to art since then
D．Instead, many are on their phones and talking
E．I found out that I have no artistic ability at all
F．Walk out of our comfort zone and try new things
G．The classes we choose can influence us in the future
三、语法填空
阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。
Zhoukoudian is a small village lying about 50 kilometers to the southwest of Beijing City.

Zhoukoudian was listed 22 a World Heritage Site in December 1987. It has not only given 23 (we) important information about prehistoric Asian societies, but also provided amazing evidence about the process of evolution. Today, parts of the caves have been badly destroyed by rain. Some areas are almost 24 (complete) covered in weeds, causing serious damage. Also, pollution 25 (cause) by the nearby factories has contributed to the problem.This is a very serious matter. The Chinese Academy of Sciences is doing all it can 26 (raise) public awareness of it.

The day when the jobs were handed out was one of the most exciting for all the children in the class. It took place during the first week of the term. On that day, every boy and girl was given a job for which they would be responsible for the rest of that school year.
As everything else, some jobs were more interesting, and the children were eager to be given one of the interesting ones. When giving them out, the teacher took into account which children had been most responsible during the previous year, and those children were usually the ones who most looked forward to this day. Among them Rita stood out. She was a kind and quiet girl; and during the previous year she had carried out the teacher’s instructions perfectly. All the children knew Rita was the favourite to be given the best job of all—to look after the class dog.
But this year there was a big surprise. Each child received one of the normal jobs, like preparing the books or the radio for the lessons, telling the time, cleaning the blackboard, and looking after one of the pets. But Rita’s job was very different. She was given a little box containing some sand and some ants. And even though the teacher insisted that they were very special ants, Rita couldn’t help feeling disappointed. Anyway, she accepted the task. Most of her classmates felt sorry for her. They sympathised with her and remarked on how unfair it was that she had been given that job. Even Rita’s father felt sorry for her, and as an act of protest, he told Rita to pay no attention to this insignificant pet. However, Rita, who liked her teacher very much, preferred to show the teacher her ability by doing something special with such an insignificant task. “I will turn this ‘little task into something great,” Rita said to herself.

27. To beautify the environment and promote our environmental awareness, our school organized a tree-planting activity on March, 12 -- Chinese Arbor Day.
Early in the morning, we took a bus to the fantastic Jiangtan Park. Upon arrival, beside a path with nothing on both sides, bundles of small trees jumped into our sight. No sooner had we been told to plant the small trees along the path than we set to work with high spirits. Shortly afterwards, lines of small trees began to stand beside the path that had just been bare. In less than half a day, our task was perfectly completed. Though tired, we were fully filled with a sense of achievement.
Through this activity, our enthusiasm for participating in physical work has been fostered. Meanwhile, we have a deeper understanding of beautifying and protecting the environment. What a fruitful and unforgettable activity!
28. To learn more about her little ants, Rita turned to Dr. Martinez, a famous entomologist(昆虫学家). With his help, she learned about the incredible abilities of these tiny creatures, such as their strength and organization. Rita became fascinated by the ants and started studying them with great interest. She observed their behavior, their interactions, and their construction of tunnels and mounds. She even started a small ant farm at home, carefully monitoring the growth and development of the colony. Rita realized that her seemingly insignificant task was actually a great opportunity to learn and explore the wonders of nature.
Several months later, one day, Dr. Martinez came to Rita’s class to choose a young assistant. He was looking for a bright and curious student who had shown a genuine interest in the world of insects. To everyone’s surprise, he chose Rita. She was overjoyed and felt that her hard work and dedication had paid off. As Dr. Martinez’s assistant, Rita had the opportunity to work alongside him, learning about different types of insects, their habitats, and their roles in the ecosystem. She traveled with him to different places to collect samples, and even got to participate in a research project on ant behavior.
