A.did the computer repaired                B.was repaired the computer

C.was the computer repaired                D.the computer was repaired

 

【答案】

C

【解析】

试题分析:考查Only引导的部分倒装句。Only的倒装句要满足两个条件:only放在句首,且强调的是状语。本题中only放在了句首,强调的是时间状语从句Only after his friend came,故使用部分倒装的形式、句意:只有在朋友来了以后,计算机才被修好。故C正确。

考点:考查Only引导的部分倒装句

点评:部分倒装中考查较多的有:(1) 含有否定意义的词never,seldom,little. hardly,not,scarcely,nowhere,by no means(决不)等置于句首时。(2)以only修饰作为状语的副词、介词短语或从句,且放在句首时。 注意:only 修饰状语从句放在句首时,状语从句不需要倒装,只能倒装主句部分。(3)当so置于句首意为“也如此”,neither,nor置于句首意为“也不”时。当so表示对前句内容的肯定和附和,译作“确实,正是”时,用自然语序。(4)当not only…but also, so/such…that, not… until, no sooner… than, hardly… when等连词置于句首时。(5)在as引导的让步状语从句中(名词/形容词/副词/动词+as+主谓结构)。(6)虚拟语气的条件状语从句省去 if时,须将were,had,should提到句首构成倒装句。(7)频度副词often, always, once, now and then, every other day, many a time等放在句首时。(8)为了使句子保持平衡,为了强调表语或为了使上下文紧密衔接时,常使用倒装语序。

Besides giving off gases and dusts into the air, humans produce waste that is poured on the environment. Often, this waste produced by major industries and people is harmful to both nature and human life.

One of the main causes of the large amount of dangerous waste is that people do not realize how large a problem it is. Because it can be simply removed and sent to a landfill(废渣填埋场),the problem is often believed to end there. In addition, industries have often shown an unwillingness to find ways to deal with dangerous waste because of the related expenses. Many industries and governments build simple landfills to store waste, and often just pour waste chemicals into nearby bodies of water. Often, chemicals used for industrial production cause dangerous forms of waste.The amount of these chemicals has increased greatly in the past, but it is often difficult and expensive to get rid of these chemicals or to store them in a way safe to human life and the environment.

Every year, major health problems result from dangerous waste. Sadly, it is often only after someone has died or become seriously ill that governments will take measures to reduce levels of harmful waste.

Some governments have realized how serious the dangerous waste problem is and are now trying to settle this problem. They are also trying to limit the amount of waste industries are allowed to produce.

Not only governments but ordinary people as well must work together to solve the problem. They can choose not to buy those products which require the production of dangerous waste, and produce less harmful waste themselves. Many scientists think that waste production can be cut. The waste can be reduced by at least one third using existing technologies and methods.
