第一节(共15小题；每小题2分，满分30分)
阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。
A
Taking your English into the real world
There is nothing quite like trying out your English in a country where the natives speak it fluently. Chen Yuan, a 24-year-old senior from Fudan University, Shanghai, faced a series of challenges while visiting Europe, Australia and the US.
What was the first thing you noticed when you arrived
When I first arrived, my biggest problem was that I didn’t know any sla ng terms (俚语). I was greeting people with, "How are you" while everyone else was saying, "What’s up" I was finding it hard to communicate with local people even when they used simple words.
What were the differences between the English you learned in the classroom, and the English you had to use abroad In the classroom I would remember patterns of speech. I knew that when someone asked, "How are you" I should reply, "Fine, thank you. And you" The problem came when people replied to me in different w ays. I didn’t know how to continue the conversation.
What was the hardest thing to adapt to
Life in the West is very different. In the US I found it hard to travel about, as there was not much public transport. In New York there may be a subway, but it was hard to find a bus. In some smaller cities, everyone drove a car. It is not easy for a backpacker to travel around these places. I also didn’t enjoy a lot of the food, because I think I was too used to Chinese cooking.
Tell us a funny story from your time abroad
When I first arrived in Britain, I wanted to buy some shoes, but didn’t know the word for pigskin or leather. I asked the salesman, "Are the shoes made of beef or pork" I still remember the look on his face.
21. What was Chen Yuan’s biggest barrier when she first arrived abroad
A. How to communicate.
B. How to travel.
C. What to eat.
D. What to buy.
22. What probably was the root of her communication problems
A. The way she greeted people
B. The way people replied to her
C. The way she started a conversation
D. The way she learned English in class
23. Which means of transport worried Chen Yuan in New York
A. Bus.
B. Car.
C. Subway.
D. Railway.
24. Where can we most probably find this article
A. In a travel brochure.
B. In a daily newspaper.
C. In a historical novel.
D. In a fashion magazine.
B
I had an unannounced visit from an unwelcome guest last night. My PC was hit by a virus and I spent all night dealing with the mess it caused. I don’t really know when it happened but the problems just started coming out suddenly last night.
Luckily I had just backed up all my documents a week before but I’m still working on getting the operating system up and running. When I set up the computer a few years ago I went through and created recovery CDs, so I’m trying to use those to recover the PC back to the way it was out of the box.
I’m not exactly sure how the virus came onto my PC but I was behind on both my anti-virus updates and Windows updates so I imagine that had something to do with it. This was not exactly the way I was planning on spending my evening and morning. I absolutely hate wasting time on productivity (生产率) black holes like this. I wonder how many hours of productivity are lost each year due to the effects of viruses.
Anyhow, it may be a day or two before I’m back up and going again. Needless to say there will be some upcoming mails on backing up your data, keeping current (现在的) on your updates, and a review of the best anti-virus software.
25. What happened to the author’s computer
A. The software was lost.
B. His documents were stored.
C. Someone came and stole it.
D. A deadly virus dropped by.
26. Why did the author hate productivity black holes so much
A. His time was wasted.
B. They ruined all the files.
C. His PC was out of the box.
D. He was behind on updates.
27. What will the author have to do before the problem is solved
A. Buying software.
B. Updating software.
C. Reviewing the data.
D. Creating recovery CDs.
C
We’re used to watching the price of oil mock gravity, but there’s an even more necessary product that’s also become scarcer and more expensive in recent months: Traders are paying record prices for wheat on world markets, thanks in part to shortages caused by a mix of droughts (干旱) and flooding. Canada, the second-biggest wheat producer after the ., looks set to harvest its smallest crop in five years, due to an unusually dry July, while production in the European Union and Australia may be down nearly 40% from last year after flooding rains followed long droughts. Growing global demand for biofuels is also eating up grain production, and putting up prices.
As a result of the supply squeeze, global stores of wheat — which makes up one-fifth of the world’s food intake — are expected to fall to their lowest level in 26 years, according to the . Department of Agriculture.
Tighter supplies mean American consumers will be paying a few cents more for everything from bread to sandwiches to hamburgers, as meat supplies can be tied to grain prices. And, if the world warms as expected over the coming decades, the terrible farming year of 2016 may be just the beginning. As temperatures rise, many studies predict that crop productivity will decline, as the extreme droughts and floods that damaged this year’s wheat crops become more common. The richest land is likely to be found further north in response to the heat, opening up the possibility of agriculture in areas such as Siberia that has long been too cold for good farming. But the same effect could turn today’s bread-basket regions as the American Midwest into dust bowls.
28. Which of the following can best replace the underlined part “mock gravity” in Paragraph1
A. change
B. close
C. increase
D. decrease
29. Which area is thought to produce the most wheat in the world
A. .
B. Canada.
C. Australia.
D. European Union.
30. What does the author suggest by mentioning Siberia in the last paragraph
A. Food prices will shoot up.
B. Extreme weather might stay.
C. It used to be suitable for farming.
D. Farming methods have improved.
31. What does the passage mainly talk about
A. Crop productivity.
B. Extreme weather.
C. Wheat shortage.
D. Severe droughts.
D
There have been claims that warming on Mars and Pluto is proof that the recent warming on Earth is caused by an increase in solar activity, and not by greenhouse gases. But we can say with certainty that, even if Mars, Pluto or any other planet has warmed in recent years, it is not due to changes in solar activity.
The Sun’s energy output has not increased since direct measurements began in 1978. If increased solar output really was responsible, we should be seeing warming on all the planets and their moons, not just Mars and Pluto.
Our solar system has eight planets, three dwarf planets and quite a few moons with at least a thin atmosphere, and thus a climate of sorts. Their climates will be affected by local factors such as orbital variations, changes in reflectance and even volcanic eruptions, so it would not be surprising if several planets and moons turn out to be warming at any one time.
One theory is that winds have recently swept some areas of Mars clean of dust, darkening the surface, warming the Red Planet and leading to further increases in windiness --- a positive feedback effect.
Observations of the thickness of Pluto’s atmosphere in 2002 suggested the dwarf planet was warming even as its orbit took it further from the Sun. The finding confused astronomers at the time, and the cause had yet to be determined.
It has since been suggested that this is due to a greenhouse effect: As it gets closer to the Sun, Pluto may warm enough for some of the methane ice on its surface to turn into a gas. This would cause further warming, which would continue for a while even after Pluto’s orbit starts to take it away from the Sun.
32. What cause(s) the warming of some planets
A. The solar system.
B. Their local factors.
C. Volcanic mountains.
D. The thin atmosphere.
33. What is the outcome of the recent winds on Mars
A. They’ve cooled the planet.
B. They’ve left a clear sky.
C. They’ve caused more winds.
D. They’ve helped clean the planet.
34. What do we know about the thickness of Pluto’s atmosphere
A. It remains mysterious.
B. It troubled astronauts.
C. It has become thinner.
D. It contributes to the warming.
35. Which of the following might lead to the warming on Earth according to the writer
A. Solar activity.
B. Mars and Pluto.
C. Greenhouse gases.
D. T he Sun’s energy output.

Dear Peter,
I’m so delig hted to receive your letter and know you are safe back. Thank you for sending me the book, which is really a feast of western culture. I enjoy reading it very much.
Since you seem to be surprised at the fact that in China, three generations---grandparents, parents and children, often live together, it will be my pleasure to explain this phenomenon to you. As our living
conditions improve, it’s unnecessary for several generations to live together any more. However, many Chinese still tend to live together because they can help and care for each other. Besides, by living together, all family members can develop a strong sense of belonging, as well as strengthen their emotional bonds.
Hope to host you in China again. Looking forward to your reply.
Yours,
Li Hua

②高值区多集中于近海沿岸和地势较高的地区 ③在黄河人海口附近的滩涂，土壤盐分含量较低 ④1996年黄河人为改道后新生湿地含盐量明显低于改道前形成的湿地 A. ①②③ B. ②③④ C. ①③④ D. ①②④ 3. 黄河三角洲新生湿地氮、磷等营养元素的分布特点是 A. 总氮含量整体上呈现出由河道两侧向外递增 B. 总氮含量低值区集中在近海滩涂地区 C. 总磷含量整体上由海向陆递减 D. 总磷含量整体上由河道向外递增 【答案】1. B 2. C 3. B 【解析】 1. 黄河流经水土流失严重的黄土高原，导致黄河含沙量极大，黄河携带大量泥沙向渤海推进，在入海口处沉积，从而使黄河三角洲湿地成为世界上土地面积自然增长最快的自然保护区。 2. 河水为淡水，含盐量低，故含盐量整体上由河道两岸向外侧递增，①对。近海沿岸有河流的稀释作用，含盐量低，②错。在黄河入海口附近的滩涂受黄河水稀释，土壤盐分含量较低，③对。人为改道后新生湿地由黄河径流堆积而成，含盐量低，改道前形成的湿地受海洋影响，含盐量较高，④对。选C。 3. 读材料可知：“黄河三角州滨海湿地系统中磷主要是陆源磷”，即磷主要来自陆地，故总磷含量整体上应由陆向海递减、由河道向外递减，C、D错。“氮主要来自植物的分解输入”，故氮含量应与植物的分布一致，近海滩涂地区植物较多，故总氮含量低值区集中在近海滩涂地区，B对、A错。 【点睛】 影响海水盐度的因素主要有降水量、蒸发量、径流量等因素。①降水量越大，盐度越低。②蒸发量越大，盐度越高。③河口地区陆地径流注入越多，盐度越低。 峡谷是在新构造运动迅速抬升和流水下切侵蚀作用下形成的谷地，是一种两壁狭长且陡峭、深度大于宽度的地貌景观。下图示意太行山峡谷横剖面。据此完成下面小题。
