C
After years of heated debate, gray wolves were reintroduced to Yellowstone National Park. Fourteen wolves were caught in Canada and transported to the park. By last year, the Yellowstone wolf population had grown to more than 170 wolves.
Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States, but they were gradually displaced by human development. By the 1920s, wolves had practically disappeared from the Yellowstone area. They went farther north into the deep forests of Canada, where there were fewer humans around.
The disappearance of the wolves had many unexpected results. Deer and elk populations — major food sources (來源) for the wolf – grew rapidly. These animals consumed large amounts of vegetation (植被), which reduced plant diversity in the park. In the absence of wolves, coyote populations also grew quickly. The coyotes killed a large percentage of the park' s red foxes, and completely drove away the park' s beavers.
As early as 1966,biologists asked the government to consider reintroducing wolves to Yellowstone Park.They hoped that wolves would be able to control the elk and coyote problems.Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets.
The government spent nearly 30 years coming up with a plan to reintroduce the wolves. The U.S.Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone. Today, the debate continues over how well the gray wolf is fitting in at Yellowstone. Elk,deer,and coyote populations are down,while beavers and red foxes have made a comeback.The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.
（1）What is the text mainly about?
A.Wildlife research in the United States.
B.Plant diversity in the Yellowstone area.
C.The conflict between farmers and gray wolves.
D.The reintroduction of wolves to Yellowstone Park.
（2）What does the underlined word “displaced” in paragraph 2 mean?
A.Tested.
B.Separated.
C.Forced out.
D.Tracked down.
（3）What did the disappearance of gray wolves bring about？
A.Damage to local ecology.
B.A decline in the park's income.
C.Preservation of vegetation.
D.An increase in the variety of animals.
（4）What is the author's attitude towards the Yellowstone wolf project？
A.Doubtful.
B.Positive.
C.Disapproving.
D.Uncaring.

【題目】閱讀下列短文：根據(jù)短文做出正確的回答。
Walking will be banned on escalators as part of a trail designed to reduce congestion(擁堵) at some of the country's busiest stations.
In the first move of its kind, all travelers will be forced to stand on both sides of escalators on the London Underground as part of a plan to increase capacity(容量) at the height of the rush hour.
A six-month trial will be introduced at Holborn station from mid-April, eliminating the rule of standing on the right and walking on the left. The move, imitating a similar structure in Far eastern cities such as Hong Kong, is designed to increase the number of people using long escalators at the busiest times. It could be expanded across the Tube network in coming years.
According to London Underground, only 40percent of travelers walk the full length of long escalators, leaving the majority at the bottom as they wait to get on to the “standing “side.
A three-week trial at Holborn last year found that the number of people using escalators at any time of could be raised by almost a third. Peter McNaught, operations director at London Underground, said: “It may not seem right that you can go quicker by standing still, but our experiments at Holborn have proved that it can be true. This new six-month trial will help us find out if we can influence customers to stand on both sides in the long term.”
Holborn has one of the longest sets of escalators on the Underground network at 23.4high. Tube bosses claim that capacity was limited because so few people wanted to walk up—meaning only one side was used at all times. Research has shown that it is more effective use of escalators over 18.5 to ban walking.
The previous trial found that escalators at the station normally carried 2,500people between 8:30 am and 9:30 am on a typical day, rising to 3,250 during the researching period.
In the new trial, which will be launched from April 18, one of three “up” escalators will be standing only, with a second banning walking at peak times. A third will remain a mix of walking and standing.
(Note: Answering the questions or complete the statements in NO MORE THAN TEN WORDS.)
（1）What is theexisting problem with standing on the right and walking on the left?
（2）What did last year's three-week trial at Holborn station prove?
（3）The researchsuggests that walking should be forbidden on escalators that are at least in height.
（4）In the new trail,in addition to one escalator banning walking in rush hours, the other ＂up＂ escalators willbe used for.

【題目】Everywhere I look outside my home I see people busy on their high-tech devices, while driving, walking, shopping, even sitting in toilets. When connected electronically, they are away from physical reality.

People have been influenced to become technology addicted. One survey reported that "addicted" was the word most commonly used by people to describe their relationship to iPad and similar devices. One study found that people had a harder time resisting the allure(誘惑) of social media than they did for sleep, cigarettes and alcohol.

The main goal of technology companies is to get people to spend more money and time on their products, not to actually improve our quality of life. They have successfully created a cultural disease. Consumers willingly give up their freedom, money and time to catch up on the latest information, to keep pace with their peers or to appear modern.

I see people trapped in a pathological(病態(tài)的) relationship with time-sucking technology, where they serve technology more than technology serves them. I call this technology servitude(奴役). I am referring to a loss of personal freedom and independence because of uncontrolled consumption of many kinds of devices that eat up time and money.

What is a healthy use of technology devices? That is the vital question. Who is really in charge of my life? That is what people need to ask themselves if we are to have any chance of breaking up false beliefs about their use of technology. When we can live happily without using so much technology for a day or a week, then we can regain control and personal freedom, become the master of technology and discover what there is to enjoy in life free of technology. Mae West is famous for proclaiming the wisdom that "too much of a good thing is wonderful." But it's time to discover that it does not work for technology.

Richard Fernandez, an executive coach at Google acknowledged that "we can be swept away by our technologies." To break the grand digital connection people must consider how life long ago could be fantastic without today's overused technology.

【1】From the passage, technology companies aim to _________.

A. attract people to buy their products B. provide the latest information

C. improve people's quality of life D. deal with cultural diseases

【2】It can be inferred from this passage that people _________.

A. consider too much technology wonderful

B. have realized the harm of high-tech devices

C. can regain freedom without high-tech devices

D. may enjoy life better without overused technology

【3】What's the author's attitude towards the overusing of high-tech devices?

A. Neutral(中立的). B. Skeptical(懷疑的).

C. Disapproving. D. Sympathetic.

Dear Mother,

Sorry to tell you the recent test has failed me. Here is the reasons. Firstly, the wrong belief is that led to failure. I have held the belief that it is not use doing well in school. Good grades can’t surely bring us beef. In addition to, I am lacking in hard work at learning. What’s most terrible is that I spend too many time in collecting old stamps. To do well in school in the near future, we have made a plan, hoping it will pay off. From now on, I will pay more attention to subject learning. After all , as a student, learning is of greatly importance. Only by working hard can one make progress. At same time, I will turn to my teachers and classmates for advices or help actively if I come across some problems.

Yours Sincerely

Jenny
