Question

【题目】阅读理解
Cycling or even walking in city areas can be a little dangerous, thanks to the fact that one is sharing the road with vehicles that are increasingly getting larger and heavier. A recent study proves that of the 1.27million people that die in road traffic crashes each year, about half are walkers, motorcyclists and cyclists. Now there may be a solution that could provide at least some help to protect this helpless group---an airbag!
If you are worried that this safety measure will involve you taking around a heavy package or worse still, wrapping yourself inside an ugly plastic bag, the bag is fitted not on the human, but on the outside of the vehicle. And, while there are several versions of the idea in the works, the one most recently unveiled by Dutch car company TNO, seems to be the most advanced and ready to go into production.
In the works since 2011, the airbag covers only the lower part of the windshield. This will provide the much needed buffer(缓冲)between the person's head and the pane of glass he/she would otherwise meet.
The chain of events leading to an airbag cause are quite simple---A camera fitted beneath the rear-view mirror monitors the vehicle's closeness to a walker or cyclist. Any contact with either one of them sets off the sensors in the car's bumper and quickly blows up the airbag. In addition to that the sensors also set off the car's automatic brake, reducing the chances if an even worse injury.
In tests conducted using a model, the success of not getting injured after being hit by a car travelling at about 40km/h was about 50-50! While not perfect, it will still result in reducing the number of deaths by a huge amount.
With TNO ready to license its technology to car makers and many more companies trying to develop similar concepts, we would not be surprised if outer airbags become a standard feature in every car pretty soon.
（1）Why does the airbag cover the lower part of the windshield?
A.To protect the windshield from being destroyed.
B.To make the vehicle look beautiful.
C.To reduce the weight of walkers.
D.To prevent people's head crashing on the glass.
（2）The fourth paragraph is mainly about__________.
A.how the airbag works
B.where the airbag is fixed
C.why the airbag is safe
D.what the airbag is made up of
（3）The writer thinks the airbag of TNO____________.
A.perfect
B.practical
C.expensive
D.useless
（4）What is the main idea of the passage?
A.Airbags are a new standard feature in cars.
B.Airbags are much safer for drivers now.
C.Airbags are practical for walkers and cyclists.
D.Airbags are a solution to higher car accident rates.

Answer 1

【答案】
（1）D
（2）A
（3）B
（4）C
【解析】本文为介绍说明文。文章介绍了一种可以安装在汽车外部，用以保护行人或骑车人的新型安全气囊。

（1）推理判断题。根据第三段中的This will provide the much needed buffer(缓冲)between the person's head and the pane of glass he/she would otherwise meet.可推知，安全气囊只覆盖挡风玻璃的下部，是因为这将在人的头和玻璃之间提供一个急需的缓冲区。故选D。

（2）段落大意题。根据第四段的描述可知，本段主要描述这款安全气囊是如何运作的。故选A。

（3）观点态度题。根据倒数第二段中的While not perfect, it will still result in reducing the number of deaths by a huge amount.可知，尽管这款安全气囊还不完美，但是它将仍然能大量减少死亡人数。由此可知，作者认为TNO的安全气囊还是有实用价值的。故选B。

（4）主旨大意题。通读全文可知，本文介绍了一种可以安装在汽车外部，用以保护行人或骑车人的新型安全气囊，文章围绕这款安全气囊如何对行人或骑车人形成保护而展开，论述了它的实用价值。故选C。
