18.The question of English will keep on changing in the future is easy since it is certain that this process will continue.( )A. | if; to answer | B. | whether; to be answered | ||
C. | whether; to answer | D. | if; to be answered |
分析 考查不定式,句意:英语是否会继续变化这个问题很容易回答,因为过程会继续这是一定的.
解答 答案:C,第一个空是of后跟的宾语从句,表示"是否"在介词后的宾语从句只能用whether引导,形容词后跟不定式,常用主动形式表示被动意义.故选C.
点评 引导宾语从句,一般既可用whether也可用if.但
1. or not放在whether之后时,只能用whether不用if.
I don't know whether or not he will come.我不知道他是不是回来.
注1:如果or not放在whether所引导的从句句尾,则可以用if来替换.
I don't know whether/if he will come or not.我不知道他是不是回来.
2 在强调任意选择时,用whether…or,此时不用if替换whether.
He asked me whether I wanted to go there by train or by bus.他问我是想乘火车还是坐公共汽车去那里.
注:whether和or一起还有"不管"之意,引导让步状语从句.
Whether he drives or takes the train,he will be here on time.不管开车来还是乘火车来,他都会准时到.
3从句作介词宾语时只用whether不用if.
It depends on whether it will be fine.那得看是不是晴天.
4 作discuss等动词的宾语时,用whether不用if.
We discussed whether we should close the shop.我们讨论是不是该关掉商店.
