Pushbike Danger
Low speed bicycle crashes can badly injure一or even kill一children if they fall onto the
ends of the handlebars（车把）.So a team of engineers is redesigning it to make it safer.
Kristy Arbogast,a bioengineer at the Children's Hospital of Philadelphia in
Pennsylvania,began the project with her colleagues.The cases they reviewed about
serious abdominal（腹部的）injuries in children in the past 30 years showed that more than
a third were caused by bicycle accidents."The task was to identify how the injuries occurred
and come up with some countermeasures."she says.
By interviewing the children and their parents,Arbogast and her team were able to
reconstruct many of the accidents and identified a common cause for serious injuries.They
discovered that most cases occur when children hit an obstacle at slow speed,causing
them to topple（摇摆）over. To maintain their balance the children turn the handlebars
through 90 degrees一but their momentum（冲力）forces them into the end of the
handlebars.The bike then falls over and the other end of the handlebars hits the ground,
pushing it into their abdomen（腹部）.
The solution the group came up with is a handgrip（握柄）fitted with a spring and
damping（减速）system. The spring absorbs up to 50 per cent of the forces transmitted
（传递）through the handlebars in an impact. The group hopes to commercialize the device,
which should add only a few dollars to the cost of a bike."But our task has been one of
education because up until now,bicycle manufacturers were unaware of the problem."
says Arbogast.The advantage of the new handgrip is that
A:it can be made cheaply.
B:it reduces the impact in bicycle accidents.
C:it helps to slow down the speed of the bicycle.
D:it sells well at bicycle shops.答案：B解析： -

问答题◆Topic 11：On Bicycle Theft Questions for reference: 1) Is bicycle theft commonly seen on campus? 2) What are the causes for the theft? 3) What can universities you to stop such phenomenon?正确答案： 【参考答案】
Bicycle theft is very common on campus, which is immoral and illegal. And it is damaging to the academic image of the colleges and universities.
There are several reasons for this. First, the security system of the school should be partially responsible for the losses. Besides, more than too often, students’ carelessness leaves opportunities for the thieves. Sometimes when they have to leave their bicycles for 10 minutes, they will not take the trouble to lock them. The last point that is also worth mentioning is that there is a lack of moral education in most schools.
Considering these situations, the school and the students should work together to fight against this phenomenon On the one hand, the school security system should be perfected. On the other hand, students should learn to he more allergic. Above all, moral education must be added and emphasized. 解析： 暂无解析 -
第23题：
问答题The bicycle is a relatively recent invention. It is by far the most economical and environmentally friendly mechanical mode of transport yet invented. Describe how the illustrated two-wheeled bicycle below functions, and be sure to mention in your description the machine’s environmentally-friendly feature. You should write at least 120 words.正确答案：
As we know, bicycle is cheap, easy to operate, and convenient. Surly, it is one of the most useful transportation man has ever invented.
As we can see in the picture, the saddle is designed to be of triangular shape, which makes the rider more comfortable. The pedals can revolve flexibly in response to the feet. The pedals give force to the chain which accordingly drives the wheel. As is illustrated, the original force for the bicycle to move is human’s power instead of fuel or other resources, therefore, it is resource-saving and free of pollution. When you need to slow down, just put on the brake.
From the above analysis, we can see that the bicycle is not only a useful transportation, but also an excellent fitness equipment. It should always be our best choice.解析： 暂无解析 -
