Bicycles, a long-forgotten vehicle that seems to belong to the last century, are returning to the streets of Guangzhou, as the city starts to ban the running of motorcycle in urban Guangzhou.
“Business has never been so good for my shop,” said Chen Yongwu, a bicycle shop owner at the city’s Donghua West Road, “I have to work 12 hours a day to meet the demand of my customers. ”
“Even my wife and brother-in-law have to give me a hand lately. ”
Chen originally ran a motorcycle repair shop.  He grasped the opportunity of the motorcycle ban, and started his bicycle business soon after hearing about the banning.
“I sold 23 bicycles on January 2 alone. ” Said Chen.
Bicycle is more convenient and healthier
“My home is one kilometer from the metro station,” said a middle-aged man who is waiting for his bicycle at Chen’s shop, “it is too tiresome to walk to the station, but taking a bus for such a short distance is a waste of money. ”
“So I decided to buy a bicycle. ”
The bicycle costs around 600 yuan, which is equal to the bus fare of half a year.
“Besides, riding a bicycle to work is much healthier than riding a bus. ”
The bicycle buyers can be categorized into two groups.  One group of buyers buy the bicycles for the transportation of small commodities; the other ride the bicycles to work.
Arising problems
Riding a bicycle to work may be healthy, but it is not without problems.
The lack of bicycle lanes has posed a big threat to the safety of the bicycle riders in Guangzhou.
“I was riding my bicycle on Huifu West Road on day,” said Mr.  Zhang, “then suddenly the bus pulled over besides me near the bus station. ”
“I was so frightened at the time, because the bus nearly hit me. ”
The sideways in Guangzhou are usually crowded with foot passengers, so citizens also could not use the sideways.
“It is worse than walking. ”
Besides, finding a place a park the bicycles could be very difficult, much more difficult then finding a place to park your car.
【小题1】What is the min topic of the passage?

The willful blindness  in hockey toward concussions (头部撞击) has dropped. Hockey Canada has followed the lead of USA Hockey in preventing bodychecking (身体拦截) below age 13. A bad head injury of Sidney Crosby, the hockey's greatest star, opened the eyes of hockey people everywhere. This country's children have been facing similar danger at early ages, and Hockey Canada had to deal with a deep worry in the minds of Canadians to make the rule change. The liking for bodychecking from an early age is part of what makes Canadian hockey what it is.

    The change in rules should be taken as a chance to draw special attention to skill development in an environment free of danger.  It may also control the loss of thousands of young players who don't enjoy that environment.

    For years, many Canadian hockey parents and coaches have insisted that bodychecking at early ages is necessary to ensure that players can do it safely at older ages. True or not, there may be a safer way to teach hitting than to make younger players pay a price for it in head injuries. When USA Hockey changed its rules for the 2011-2012 season, it also created bodychecking-education programs that will be mandatory(强制的) for all coaches,  including those teaching players in  the pre-checking ages. And it began to encourage more "touch" - without real bodychecking - from 9 t0 12. It also made the rules for 13 and up stricter. The USA is trying to show that it's possible to teach hockey protective skills without putting11 and 12-year-olds in greater danger. It's worth the try.

    Hockey Canada has taken serious steps to do away with hits on the head. However, it's hard to change a sports culture so connected with who we are as a country. Too often, bodychecking has been used to try to separate a player from his head rather than from the ball. Children were paying a price for this country's love of the game.

    There are always changes in Canada's game, and the change in the bodychecking age sends the clearest message yet to coaches and parents that player safety is paramount(至上的) in the game.

4.What is probably the best title' for this passage?

Biodiversity(生物多样性), or biological diversity, is a wide-ranging concept that covers all the different kinds of plant and animal species present on earth. Environmentalists believe that many millions of species exist. As all these living organisms are dependent on each other in some way, biodiversity is desirable. Any loss to the planet is actually a loss for mankind as well, and it is our responsibility to try and save Earth’s biodiversity.
Biodiversity has a vital role to play in the evolution（演变）of species. Species become extinct, but new species evolve, and this is how a balance is maintained. This may sound pretty simple, but it takes millions of years for changes to take place.
Biodiversity is also very important to the stability of food webs. Damage to them can mean disaster for an entire ecosystem. The extinction of a single animal species can put huge pressure on the numerous other species dependent on it.
Biodiversity also has an important role to play in human society. Apart from being the most intelligent species on earth, human beings are also the most dependent. We depend on nature to meet our basic needs. When we change the balance of nature to create our cities and bring about our technical advances, we knowing or unknowing cause great damage to the ecosystem. This must be understood, and the damages must be reversed（颠倒）in any way they can to ensure that the balance of the ecosystem is maintained.
【小题1】We learn from the first paragraph that_________.
A biodiversity can be seen
B all living species are found on earth.
C people everywhere are aware of the importance of biodiversity
D the loss of any species can affect humans
【小题2】Why can change in food webs lead to disaster?
A Because it can make people suffer from disease
B Because it can put huge pressure on some species
C Because it takes a long time for such changes to take place
D Because it will damage ninety-nine percent of species
【小题3】What does the underlined word probably mean?
A 画线  B Peace  C Strength  D Variety
【小题4】We learn from the last paragraph that __________.
A humans are as independent as they are intelligent
B the balance of the ecosystem is easily maintained
C nature has given us a lot
D nature is taking revenge on us
【小题5】Which of the following may be the best title for this passage?
A Food Webs are Closely Related to Biodiversity.
B Biodiversity Plays a Very Important Role in Evolution
C How Biodiversity Affects Human Society.
D Understanding Biodiversity and Its Importance.
