It is reported that conservation groups in North America have been arguing about the benefits and dangers of wolves. Some groups believe wolves should be killed. Other people believe wolves must be protected so that they will not disappear from the wilderness (荒野)
For Killing Wolves
In Alaska, the wolf almost disappeared a few years ago, because hunters were killing hundreds of them for sport. However, 1aws were established to protect the wolves from sportsmen and people who catch the animals for their fur. So the wolf population has greatly increased. Now there are so many wolves that they are destroying their own food supply.
A wolf naturally eats animals in the deer family. People in the wilderness also hunt deer for food. Many of the animals have been destroyed by the very cold winters recently and by changes in the wilderness plant life. When the deer can’t find enough food, they die.
If the wolves continue to kill large numbers of deer, their prey (猎物) will disappear some day. And the wolves will, too. So we must change the cycle of life in the wilderness to balance the ecology(生态平衡). If we killed more wolves, we would save them and their prey from dying out. We’d also save some farm animals.
In another northern state, wolves attack cows and chickens for food. Farmers want the government to send biologists to study the problem. They believe it necessary to kill wolves in some areas and to protect them in places where there is a small wolf population.
Against Killing Wolves
If you had lived long ago, you would have heard many different stories about the dangerous wolf. According to most stories, hungry wolves often kill people for food. Even today, the stories of the “big bad wolf'” will not disappear.
But the fact is wolves are afraid of people, and they seldom travel in areas where there is a human smell. When wolves eat other animals, they usually kill the very young, or the sick and injured .The strongest survive .No kind of animal would have survived through the centuries if the weak members had lived. And has always been a law of nature.
Although some people say it is good sense to kill wolves, we say it is nonsense! Researchers have found wolves and their prey living in balance. The wolves keep the deer population from becoming too large, and that keeps a balance in the wilderness plant life.
The real problem is that the areas where wolves can live are being used by people. Even if wilderness land is not used directly for human needs, the wolves can’t always find enough food. So they travel to the nearest source, which is often a farm. Then there is danger. The“big bad wolf”has arrived! And everyone knows what happens next.
Some people are against killing wolves because ________.

A.there are too many deer in the wilderness
B.wolves are afraid of people and never attack people
C.wolves help to keep the ecological balance in the wilderness
D.there is too small a wolf population in the wilderness

According to those against killing wolves, when wolves eat other animals, ________.

A.they might help this kind of animals survive in nature
B.they disturb the ecological balance in the wilderness
C.they never eat strong and healthy ones
D.they always go against the law of nature

The last sentence “And everyone knows what happens next” implies that in such cases _______.

A.wolves will find enough food sources on farms
B.people will leave the areas where wolves can live
C.farm animals will be in danger and have to be shipped away
D.wolves will kill people and people will in turn kill them

Have you ever had the strange feeling that you were being watched? You turned around and, sure enough, someone was looking right at you!
Parapsychologists (灵学家) say that humans have a natural ability to sense when someone is looking at them. To research whether such a “sixth sense” really exists, Robert Baker, a psychologist (心理学家) at the University of Kentucky, did two experiments.
In the first one, Baker sat behind unknowing people in public places and stared at the backs of their heads for 5 to 15 minutes. The subjects(受试者)were eating, drinking, reading, studying, watching TV, or working at a computer. Baker made sure that the people could not tell that he was sitting behind them during those periods. Later, when he questioned the subjects, almostall of them said they had no sense that someone was staring at them.
For the second experiment, Baker told the subjects that they would be stared at from time to time from behind in a laboratory setting. The people had to write down when they felt they were being stared at and when they weren’t. Baker found that the subjects were no better at telling when they were stared at and when they weren’t.
Baker concludes that people do not have the ability to sense when they’re being stared at. If people doubt the outcome of his two experiments, said Baker, “I suggest they repeat the experiments and see for themselves.”
The aim of the two experiments is to________.

A.explain when people can have a sixth sense
B.show how people act while being watched in the lab
C.study whether humans can sense when they are stared at
D.prove why humans have a sixth sense

The underlined word “outcome” in the last paragraph most probably means________.

A.value B.result C.performance D.connection

In the second experiment, the subjects _________.

A.could tell when they were stared at and when they weren’t.
B.could tell when they were stared at but couldn’t tell when they weren’t.
C.couldn’t tell when they were stared at but could tell when they weren’t.
D.couldn’t tell when they were stared at or when they weren’t.

What can be learned from the passage?

A.People are born with a sixth sense.
B.The experiments support parapsychologists’ idea.
C.The subjects do not have a sixth sense in the experiments.
D.People have a sixth sense in all places.

Don’t you think it interesting that there were strange coincidences(巧合) in the deaths of President Kennedy and President Lincoln? For example, John Kennedy was elected president in 1960 while Abraham Lincoln in 1860, between which was a hundred years. Both men were killed from behind, on black Friday , and with their wives on the spot. The two men were born exactly one hundred years away, as were their murderers, Lee Oawald and John Booth. Perhaps the strangest coincidence is that President Kennedy’s secretary , whose name was Lincoln, advised the president not to go to Dallas, where the president was shot. President Lincoln’s secretary, named Kennedy, advised the president not to go to the Ford Theatre, where the president met his death.
When President Lincoln and President Kennedy were killed, their wives were_______.

A.at the cinema B.at home C.behind them D.with them

A small town in southwest Britain is banning (禁止) plastic bags in an attempt to help the environment and cut waste-a step that environmentalists believe is a first for Europe.
Shopkeepers in Modbury population 1,500, agreed to stop handing out disposable plastic bags to customers on Saturday. They said paper sacks and cloth carrier bags would be offered instead.
Last month, San Francisco became the first U.S. city to ban plastic grocery bags. Internationally, laws to discourage the use of plastic bags have been passed in parts of South Africa and Ireland, where governments either tax shoppers who use them or fine companies that hand them out. Bangladesh already bans them, and so do at least 30 remote Alaskan villages.
Modbury, about 225 miles southwest of London, has also declared a bag ammesty (宽限期), allowing local people to hand in plastic bags that have piled up at home. They will be sent for a recycling.
The Modbury ban was the idea of Rebecca Hosking, who saw the effect of bags on marine life while working in the Pacific as a wildlife camerawoman. She said response in the town so far had been “really positive”.
“Modbury is quite an old-fashioned town and a lot of people have wicker(柳条) baskets to go out shopping anyway, ”Hosking told Sky News Television.
The World Watch Institute, an environmental research agency, states that 100 billion plastic bags are thrown away each year in the United States alone. More than 500 billion are used yearly around the world.
The underlined word “disposable” in the passage probably means .

A.acceptable B.valuable C.environmentally-friendly D.long-lasting

It can be inferred from the passage that .

A.most of the people in Modbury continue to use plastic bags
B.fewer and fewer plastic bags will be used in the world
C.San Francisco is the first city to ban plastic bags in the world
D.most countries in the world have passed laws to ban plastic bags

Which of the following would be the best title of the passage?

A.Environmental Protection B.Big Cities Banning Plastic Bags
C.British Town Banning Plastic Bags D.Effect of Plastic bags on Sea Animals

US researchers have found traces of an ancient lake on Mars recently, increasing hopes of discovering evidence that billions of years ago the Red planet hosted life.
The lake, which dates back some 3.4 billion years, appears to have covered as much as 80 square miles and was up to 1,500 feet deep, said the team from the University of Colorado.
“This is the first clear evidence of shorelines on the surface of Mars,”said Boulder’ s research associate, Gaetano Di Achille, in a study published in the latest edition of Geophysical Research Letters.
“The identification of the shorelines and accompanying geological evidence allows us to calculate the size and volume of the lake, which appears to have formed about 3.4 billion years ago.”
Analysis of the images has shown the water carved out the canyon (溪谷) in which it was found, which then opened out into a valley depositing (使淤积) sediment (沉积) which formed a delta (三角洲).
“Finding shorelines is a great discovery to us,” said assistant professor Brian Hynek, adding it showed the lake existed at a time when Mars was thought to have been cold and dry.
Scientists believe the oldest surfaces on Mars formed during the wet and warm era known as the Noachan epoch, about 4.1 billion to 3.7 billion years ago.
The newly discovered lake is believed to date from the Hesperian era and postdates the end of the warm and wet period on Mars by 300 million years, according to the study.
Scientists believe deltas next to the lake may well hold secrets about past life on Mars as such places on Earth have become the natural deposits of organic carbon and other markers of life.
The size of the lake found on Mars is ______.

A.80 square miles B.1,500 square miles
C.3.4 billion square miles D.300 million square miles

When the lake existed, the weather on Mars was ____.

A.hot and wet B.wet and warm C.cold and dry D.cold and wet

Why do scientists think deltas near the lake may hold secrets about past life on Mars?

A.Because similar places on Earth have become natural deposits of markers of life.
B.Because someone has put secrets about past life on Mars there.
C.Because past life has been found in other deltas on Mars.
D.Because some people are said to have already seen life marks there.

Which of the following statements is NOT true according to the passage?

A.The Noachan epoch was a wet and warm era.
B.The lake might have existed 3.4 billion years.
C.The discovery can’ t fully prove that the Mars once hosted life.
D.The lake traces prove that there exists life on Mars now.
