试题答案

答案:B

解析:

此题题意是“只有到战争结束,他才能回国”.主要考查only+连词(when/before/after/while引导的状语从句的用法,倒装的是主句.C选项,虽能倒装,但用了could一般不再用be able to,D选项would he be able缺少to.故应选B项.

提示:

only 放于句首的三种倒装形式:only+介词短语+助动词/情态动词+主语.only+连词引导的状语从句+助动词/情态动词+主语.如果句子为主从复合句,则主句倒装,从句不倒装.only+副词+助动词/情态动词+主语.类似倒装的有not until.当其引出主从复合句时,主句倒装,从句不倒装.
