A paperclip,made of steel wire bent into a looped (环形的)shape,is an instrument used to hold sheets of paper together.This common device is a wonder of simplicity and function.But where did this simple,cheap,and practical invention come from?

In the late 19th century,the most common way to hold papers together was by using a pin.Although the pin was an inexpensive tool and was easily removable,it would 1eave holes in the paper. Later,as steel wire became more common,inventors began to notice its elastic(有弹性的)feature. With this feature,it could be stretched and twisted into various clip—like objects.In the years just before 1900,quite a few paperclip designs appeared.The name most frequently associated with the paperclip invention is Johan Vaaler,a Norwegian inventor. However, Vaaler’s clips were not the same as the paperclips currently in use.Specifically,they did not have the inside loop we see today.The familiar looped design was invented by Gem Manufacturing Ltd.in England.This clip is therefore sometimes known as the Gem clip.

Because of Vaaler,the paperclip played an important historical role in Norway.During World War II,Norway was occupied by the Nazis.Norwegians were prohibited from wearing any symbol of their national unity(团结),such as buttons with the initials of their king.Thus,in protest,they started wearing paperclips to show their unity.The reason for doing this was simple:Paperclips were a Norwegian invention whose original function was to bind together.After the war,a giant paperclip statue was put up in Oslo to honour Vaaler—even though his design was never actually produced.

1.According to the first paragraph,the paperclip is________.

A.made of paper

C.inexpensive and useful

D.for holding clothes together

2.One way the paperclip is better than the pin is that_________

3.Which of the following best shows what the Gem clip looks like?

4.The last paragraph is mainly about_________.

Mauritius, an island country, lies 1, 200 miles off the southeastern coast of Africa, and just east of Madagascar, another African island country, which is larger by far than Mauritius. It covers 788 square miles and has a population of 1, 100, 000, about 750, 000 Indians, 300, 000 Clioers, 30, 000 Chinese and 20, 000 Whites included. They are living together peacefully.

The country can be divided into many parts with different climates all because of its special terrains(地形). In the center there are volcanoes several thousand feet high, and 90 percent of its arable land is covered with sugarcane.

The chimp didn’t feel well. She fell over, ignoring the other wild chimps. Finally, the sick chimp crawled over to a bush, picked some leaves and swallowed them. By the next afternoon, the chimp was as good as new!

Biologists watching the chimp were surprised. Somehow, the plant had cured the chimp! Did the chimp know the plant would make her feel better? Or was it just a lucky accident?

Many scientists don’t think it has anything to do with luck. They’re discovering that some animals seem to use plants to cure themselves. And these animals are leading scientists to new plants that could cure humans!

Dr. Richard Wrangham, an anthropologist at Harvard University, agrees that animals may know something we don’t know about forest plants.

Wrangham got to know chimps and their diets while studying them for three years in Tanzania. “You must know a lot about an animal’s feeding habits to know what it doesn’t consider food,” Wrangham explains. Every morning, he saw that most chimps ate fruit near their nests. Later on, they ate on leaves.

When he noticed chimps eating the leaves of a plant they usually ignored, Wrangham thought something interesting was going on---especially when he saw that they’d sometimes walk for 20 minutes to find the plant. Another strange thing that caught his eye was how they ate the bitter leaves.

“They swallowed the leaves whole,” explains Wrangham, noting that chimps usually chew their food well. “They seemed to rub(摩擦)the leaves around the roofs of their mouths. They closed their eyes, wrinkled their noses and swallowed slowly. ”

Wrangham wondered what could be so good about something tasting so bad. He had a chemist analyze the leaves. He discovered that the leaves contain a red oil that kills different viruses(病毒). Later tests showed that the oil might even fight cancer and the AIDS virus!

Why don’t the chimps chew the leaves? “Rubbing the leaves between the tongue and the inside of the mouth might allow the chemicals to enter the bloodstream directly,” he suggests, “instead of going to the stomach, where they might get destroyed by acids. The chimps seem to know what they’re doing.”

1.We can learn from the passage that _________.

A. chimps cure themselves by chewing plants

B. chemicals in plants help cure animals

C. scientists live with chimps to study their diets

D. Dr. Wrangham knows a lot about forest plants

2.How can Dr. Wrangham tell which plants are medicine for chimps?

A. By talking with the biologists.

B.. By studying the chimps’ feeding habits.

C. By analyzing the chimps’ favorite food.

D. By comparing other scientists’ discoveries.

3.The author wrote the passage to ___________.

A. provide a solution B. test a theory

C. present a finding D. describe an experiment

4.What does the passage mainly talk about?

A. Animal doctors. B. Forest plants.

C. Chimp’s diets. D. A cure for cancer.

When I was a child, growing up in a small town with very little , we used to go to the station to watch the passenger trains coming in.

I took my train trip when I was ten years old. I went with my elder sister to visit our cousins six hundred miles away. The train—so loud and violent on the outside—was and rocking inside. We were very excited, and as that was also our first time away from our parents, we felt somewhat frightened too. However, because I had so much, I was a little disappointed when I was finally one of the passengers I had for so long.

As a college student, I ride overnight train to my roommate’s hometown. We could never afford a , so we played cards, sang, ate, read and talked we finally fell uncomfortably asleep in the straight-backed seats.

My idea that trains are may come from the fact that my husband and I took the train on our honeymoon, spending extra money to eat in the dining car, and the window as the desert scenery slid past.

Now, when I make a trip, I always fly or drive, and are not a very important part of my life. , every time I hear the train whistle faraway on a quiet night, I can always feel the in my heart to pack my bags and jump on board, entering a world of motions, sounds, sights, and experience which just aren’t in the dull environment of an airplane.
