B
Today, the bicycle is the primary method of transportation for the human race. About 1.6 billion bicycles are in use around the world --- in big cities, along remote country lanes, and in the smallest villages ---and hundreds of millions of bikes are produced every year to meet the continuing demand for cheap wheeled transport.
Yet the bicycle is hardly a new vision of how humans move around. Historians speculate(猜测) about Leonardo da Vinci’s 1940s drawings and a 1580s stained glass window in England that appear to describe a two-wheeler. The first widely recognized two-wheeler in actual use, however, was the pedal-less Celerifere, a toy of the French upper class in the 1970s. The more famous Draisienne followed that toy in 1816, still without pedals. The front wheel could be steered, and this two-wheeler was eventually mass-produced in Europe, particularly in England. Ernest Michaux added cranks(曲轴) to the two-wheeler in 1855, which started a revolution in human transportation --- the Velocipede.
By 1870, complicated metal Velocipede were in production in Europe and the United States. Over time, they gave way to the “Ordinary” or high-wheeler. The Ordinary was the beginning of the heyday(全盛期) of bicycling. It was speedy and capable of long trips on poor roads, so it was soon in widespread use. At that time a skilled person might earn 25 cents an hour in wages, but a good Ordinary sold for $75 to $125, making it more expensive than building a house. Nevertheless, they sold at a furious pace.
Ordinaries had a big problem, however. When the front wheel came up against any obstacle that it could not roll over, the bike simply threw the rider headfirst onto the ground. Called a “header”, this characteristic problem inspired the “safety bicycle” in the 1980s. With two wheels of equal size, plus a roller chain(齿轮) transmission, the safety bicycle was with a slight adaptation, they attracted thousands of women to cycling. Many historians point to the safety bicycle as the beginning of women’s rights.
In England, in 1909, the Raleigh bicycle, equipped with a 3-speed hub, started to be produced. In the 1930s, British-built “lightweight” bicycles, suitable for the packed earth of country roads, were being imported into the United States. The early 1980s saw the creation of the “Freestyle” or trick bicycle. And in the late 1990s, the road bike and the mountain bike proved to be the dominant machines of the decade.
Today, the bicycle continues to be the most energy and cost-efficient transportation device in the world.
What is the main idea of the first paragraph?

A.The places suited to the use of bicycles.
B.The way bicycles are used in the world.
C.The importance and popularity of bicycles.
D.The number of bikes produced every year.

We can learn from the second paragraph that____________.

Mrs. Meredith was a most kind and thoughtful woman.She spent a great deal of time visiting the poor.She knew they had problems,and they needed all kinds of help.When she had time,she would bring food and medicine to them.

One morning she told her children about a family she had visited the day before.There was a man sick in bed,his wife,who took care of him and could not go out to work,and their little boy.The little boy ﹣ his name was Bernard ﹣ had interested her very much.

"I wish you could see him," she said to her own children,John,Harry,and Clara."He is such a help to his mother.He wants very much to earn some money,but I don't see what he can do."

After their mother left the room,the children sat thinking about Bernard."I wish we could help him to earn money," said Clara. "His family is suffering so much."

Rainforests are home to a rich variety of medicinal plants, food, birds and animals. Can you believe that a single bush (灌木丛) in the Amazon may have more species of ants than the whole of Britain! About 480 varieties of trees may be found in just one hectare of rainforest.

Rainforests are the lungs of the planet ﹣ storing vast quantities of carbon dioxide and producing a significant amount of the world's oxygen. Rainforests have their own perfect system for ensuring their own survival;the tall trees make a canopy(树冠层) of branches and leaves which protect themselves, smaller plants, and the forest animals from heavy rain,intense dry heat from the sun and strong winds.

Amazingly, the trees grow in such a way that their leaves and branches, although close together, never actually touch those of another tree. Scientists think this is the plants' way to prevent the spread of any tree diseases and make life more difficult for leaf﹣eating insects like caterpillars. To survive in the forest, animals must climb, jump or fly across the gaps. The ground floor of the forest is not all tangled leaves and bushes, like in films, but is actually fairly clear. It is where dead leaves turn into food for the trees and other forest life.

They are not called rainforests for nothing! Rainforests can generate 75% of their own rain. At least 80 inches of rain a year is normal ﹣ and in some areas there may be as much as 430 inches of rain annually. This is real rain ﹣ your umbrella may protect you in a shower, but it won't keep you dry if there is a full rainstorm. In just two hours, streams can rise ten to twenty feet. The humidity(湿气)of large rainforests contributes to the formation of rainclouds that may travel to other countries in need of rain.

In May 1987 the Golden Gate Bridge had a 50th birthday party. The bridge was closed to motor traffic so people could enjoy a walk across it. Organizers expected perhaps 50,000 people to show up. Instead, as many as 800,000 crowded the roads to the bridge. By the time 250,000 were on the bridge, engineers noticed something terrible: the roadway was flattening under what turned out to be the heaviest load it had ever been asked to carry. Worse, it was beginning to sway(晃动). The authorities closed access to the bridge and tens of thousands of people made their way back to land. A disaster was avoided.

The story is one of scores in To Forgive Design: Understanding Failure, a book that is at once a love letter to engineering and a paean (赞歌) to its breakdowns. Its author, Dr. Henry Petroski, has long been writing about disasters. In this book, he includes the loss of the space shuttles (航天飞机) Challenger and Columbia, and the sinking of the Titanic.

Though he acknowledges that engineering works can fail because the person who thought them up or engineered them simply got things wrong, in this book Dr. Petroski widens his view to consider the larger context in which such failures occur. Sometimes devices fail because a good design is constructed with low quality materials incompetently applied. Or perhaps a design works so well it is adopted elsewhere again and again, with seemingly harmless improvements, until, suddenly, it does not work at all anymore.

Readers will encounter not only stories they have heard before, but some new stories and a moving discussion of the responsibility of the engineer to the public and the ways young engineers can be helped to grasp them.

"Success is success but that is all that it is," Dr. Petroski writes. It is failure that brings improvement.

(2)Which of the following is Dr. Petroski's idea according to paragraph 3?   

A.

No design is well received everywhere.

B.

Construction is more important than design.

C.

Not all disasters are caused by engineering design.

D.

Improvements on engineering works are necessary.

(3)What does the last paragraph suggest?   

A.

Failure can lead to progress.

B.

Success results in overconfidence.

C.

Failure should be avoided.

D.

Success comes from joint efforts.

(4)What is the text?   

A.

A news report.

B.

A short story.

C.

A book review.

A research article.

The end of the school year was in sight and spirits were high. I was back teaching after an absence of 15 years, dealing with the various kinds of "forbidden fruit" that come out of book bags. Now was the spring of the water pistol (手枪).

I decided to think up a method of dealing with forbidden fruit.

"Please bring that pistol to me," I said."I'm going to put it in my Grandma's Box."

"What's that?" they asked.

"It's a large wooden chest full of toys for my grandchildren," I replied.

"You don't have grandchildren," someone said.

"I don't now," I replied. "But someday I will. When I do,my box will be full of wonderful things for them."

My imaginary Grandma's Box worked like magic that spring, and later. Sometimes students would ask me to describe all the things I had in it. Then I would try to remember the different possessions I supposedly had taken away ﹣ since I seldom actually kept them. Usually the offenderwould appear at the end of the day,and I would return the belonging.

The years went by, and my first grandchild Gordon was born. I shared my joy with that year's class. Then someone said, "Now you can use your Grandma's Box." From then on,instead of coming to ask their possessions back, the students would say,"That's okay. Put it in your Grandma's Box for Gordon."

I loved talking about the imaginary box, not only with my students but also with my own children. They enjoyed hearing about all the forbidden fruit I had collected. Then one Christmas I received a surprise gift ﹣ a large, beautifully made wooden chest. My son Bruce had made my Grandma's Box a reality.

(1)What was the author's purpose in having the conversation with the students?  

A.

To collect the water pistol.

B.

To talk about her grandchildren.

C.

To recommend some toys.

D.

(2)What do the underlined words"the offender" in paragraph 8 refer to?   

A.

B.

The maker of the Grandma's Box.

C.

The author's grandchild.

D.

The owner of the forbidden fruit.

(3)What did the students do after they learned about the birth of Gordon?   

A.

B.

They asked to see the Grandma's Box.

C.

They made a present for Gordon.

D.

They stopped asking their toys back.
