Walk through the Amazon rainforest today and you will find it is steamy, warm, damp and thick. But if you had been around 15,000 years ago, during the last ice age, would it have been the same ?For more than 30 years, scientists have been arguing about how rainforests like the Amazon might have reacted(反應(yīng))to the cold ,dry climates of the ice ages ,but until now ,no one has reached a satisfying answer.
Rainforests like the Amazon are important for mopping up CO2 from the atmosphere and helping to slow global warming . Currently the trees in the Amazon take in around 500 million tons of CO2 each year; equal to the total amount of CO2 giving off in the UK each year. But how will the Amazon react to future climate change? If it gets drier ,will it still survive and continue to draw down CO2 ?Scientists hope that they will be able to learn in advance how the rainforest will manage in the future by understanding how rainforests reacted to climate change in the past.
Unfortunately ,getting into the Amazon rainforest and collecting information are very difficult .To study past climate ,scientists need to look at fossilized pollen ,kept in lake muds .Going back to the last ice age means drilling deep down into lake sediments (沉淀 物),which requires specialized equipment and heavy machinery .There are very few roads and paths ,or places to land helicopters and aeroplanes .Rivers tend to be the easiest way to enter the forest ,but this still leaves vast areas between the rivers completely unsampled(未取樣).So far ,only a handful of cores have been drilled that go back to the last ice age and none of them provide enough information to prove how the Amazon rainforest reacts to climate change.
64.The underlined phrase “mopping up” in the second paragraph means .
A.cleaning up B.taking in C.wiping out D.giving out
65.How will the Amazon rainforest react to future climate change?
A.It’ll get drier and continue to remove CO2 .
B.It’ll remain steamy ,warm ,damp and thick .
C.It’ll get warmer and then colder and drier.
D.There is no exact answer up to present.
66.What’s the main idea of the last paragraph?
A.It’s important to drill deep down into lake sediments to collect information.
B.It’s impossible to prove how climate changes in the Amazon rainforest.
C.It’s hard to collect information for studies of the past climate in the Amazon rainforest.
D.It’s necessary to have specialized equipment and machinery to study the past climate.
67.The best title for this passage may probably be .
A.Studies of the Amazon B.Climates of the Amazon
C.Secrets of the Rainforests D.Changes of the Rainforests
64---67 BDCC
64.解析:這是一道猜義題。根據(jù)下文“from the atmosphere”可猜測出mopping up的意思是“吸收”。
65.解析:這是一道細(xì)節(jié)推斷題。根據(jù)短文的最后一句話“So far,only a handful of cores have been drilled that go back to the last ice age and none of them provide information to prove how the Amazon rainforest reacts to climate change.”可推斷出目前還沒有精確的答案。
66.解析:這是一道主旨題。最后一段講述了為了研究Amazon熱帶雨林過去的氣候,科學(xué)家進(jìn)行了采集信息的工作,但是,這是一件十分困難的工作。
67.解析:這是一道主旨題。這篇短文講述了Amazon熱帶雨林的奧秘。

The Friday after the American holiday of Thanksgiving is called Black Friday. It’s said that it’s the day that store ledgers(分類賬)move into the black and companies become profitable. On that day, retailers slash(砍) prices to get consumers to buy. It is also a time when many Americans start their Christmas shopping. VOA’s Elizabeth Lee tells us how the economy may affect consumers on that bargain day.
This day should be a shopper’s dream. “It’s just the deals, the sales and everything you can get for a lesser price,” said Sandy Thomas, a shopper. But it’s a nightmare for others. “I think it’s crazy. I’ve done all of my shopping throughout the week so I don’t have to go out on Friday,” she said. It’s called Black Friday, the start of the traditional Christmas shopping season in the United States. Every year it’s the day after the Thanksgiving holiday. Stores open before sunrise and there are deep discounts everywhere you look.
Last year a crowd of bargain-hunters killed a Wal-mart worker in a New York suburb. This year, many stores are increasing security while they slash prices. “This is a huge time for the retail stores,” said Fred Joutz from George Washington University. “This is when they begin making their profits for the year.”
Economics professor Fred Joutz says how Americans spend the weekend after Thanksgiving is a good indication of how consumers feel about the future.
With the unemployment rate above 10 percent, Joutz says Americans are saving more and spending less. Some retailers are attracting consumers by opening on Thanksgiving Day, when shops are traditionally closed. Other stores open their doors anywhere from midnight to four in the morning.
And shoppers will be lining up in front of the doors in order to be one of the first ones to walk through and get a big discount. Electronics like flat screen TVs are usually the first items to go. Sandy Thomas says it’s an annual family tradition and well worth it. “I just save maybe half of what I would have spent on a regular, you know, shopping trip,” she said.
Economists say U.S. consumers will spend money this Black Friday, but they will spend it more carefully.
【小題1】By saying “This day should be a shopper’s dream”, the writer means ________ .
A.shoppers have longed for this day for a long time |
B.the shops will be very crowded on that day |
C.the shops will keep open until the daybreak of next day |
D.shoppers can buy many items at low prices on that day |
A.Because there are too many people saving more and spending less. |
B.Because it’s a time when they begin making their profits for the year. |
C.Because last year a crowd of bargain-hunters caused an accident. |
D.Because many stores open their doors from midnight to four a.m. |
A.Christmas shopping is traditional time and this year it is no exception. |
B.Electronics like flat screen TVs are usually least discounted. |
C.The economy only affects consumers on that bargain day. |
D.Thanksgiving is a good indication of how consumers feel about the future. |
A.a(chǎn) science fiction |
B.a(chǎn) travel brochure |
C.a(chǎn)n economic research report |
D.a(chǎn) book on psychology |
A.Because they organize activities in honor of some great person. |
B.Because there are too many people going out shopping for Christmas. |
C.Too many people are celebrating Thanks giving. |
D.The sky is black that day. |

Although Paris is often considered the city of romance, close to a million adults who call it home are single. Many single people say that France’s capital is one of the most difficult places to meet people. The complaints of this lonely group have inspired a new phenomenon known as “supermarket dating.” At Galerie Lafayette Gourmet,singles can shop for more than just the items on their grocery list. They can look for someone who has blue eyes, brown hair,and is 1.8 meters tall,or whatever may be on their romantic shopping list.
At this Paris location,single people of all ages can schedule their shopping for Thursday nights between 6:30 and 9:00 p.m. When they walk through the door,they pick up a purple basket to advise that they are looking for love. They try to arrive early because the baskets disappear quickly, and then they have to wait in line for their turn to wander the store aisles(過道).
With purple baskets in hand, shoppers can consider their romantic options while they pick out their groceries. When they are ready to pay, they can go to the checkout line for singles who want to chat.
Most of the people who look for love in the supermarket are skeptical of Internet dating. They know that it is easy to embellish(美化)one’s appearance or to lie about one’s age over the Internet. The supermarket, on the other hand,is considered a safe and casual environment in which to meet a potential match. In addition, what one finds in another’s grocery basket can say a thing or two about that person’s character or intentions. Buying pet food can be a man’s way of showing a potential match that he has a sensitive side. Women who fill their baskets with low-fat food show their healthy style of living. These ways it’s possible to find much more than food at a grocery store.

“Two other victims died after being transferred to hospitals in other counties,” Miller said. Witnesses said the gunman, dressed in black and wearing a stocking cap, emerged from behind a screen on the stage of 200-seat Cole Hall and opened fire just as the class was about to end around 3 pm.

“He could’ve decided to get me,” Jerome said on Friday. “I thought for sure he was gonna get me.”
Lauren Carr said she was sitting in the third row when she saw the shooter walk through a door on the right-hand side of the stage, pointing a gun straight ahead.
“I personally Army-crawled halfway up the aisle(通道),” said Carr, a 20-year-old sophomore. “I said I could get up and run or I could die here.”
She said a student in front of her was bleeding, “but he just kept running.”
