Ⅴ.阅读理解
　　Accidents happen almost every day. Some accidents are not serious but some are.
It is wrong of people to think that accidents happen only on the roads or highways, or even at the workplace. Home accidents are just as common. Because very few home accidents are reported, people come to think that there are few accidents which happen in homes.
There have been many cases where people fall to their deaths from high-rise flats. Children often fall over while coming down the stairs. Old people may slip over(滑跤) on wet floors if they are not careful.
　　Nowadays, there are a lot of modern electrical appliances(电器) like rice cookers. These appliances can kill people if they are not used in a proper way. Gas stoves(煤气炉) are also dangerous if they are not properly used. They may cause burns or, in more serious cases, even fires.
But all such accidents can be stopped if we are careful and follow simple rules of safety. For example, it is unwise of people to try repairing their own electrical appliances if they do not know how to do it. It is safer to get them repaired by an electrician(电工).
32.Accidents happen 　　　　.
A.mostly in homes
B.mostly on the roads and highways
C.mostly in factories
D.almost everywhere
33.Which of the following accidents may NOT happen in homes
A.Children often fall over while coming down the stairs.
B.People may be knocked down by cars.
C.Gas stoves may cause burns or even fires.
D.People may be killed by electrical appliances.
34.People are advised　　　　.
A.to avoid using electrical appliances
B.to repair their own electrical appliances
C.not to repair their own electrical appliances if they don't know how to do it
D.not to get their electrical appliancesfixed
答案 32-34
