⑴One third of the bread was eaten by me and the rest is[为什么这里是用is而不是are?] still on the plate
⑵Now,I will tell you what[为什么这里不是用why?] you should pay attention to in an exam
⑶If you watch carefully,you can see how[为什么这里不是用what] the man does the trick with the cards
⑷Those who[为什么这里不是用Anyone或The one who或Anyone who] have finished the work can leave
⑸Do you know whether they are leaving for[为什么不能用whether they leave for或whether will they leave for]Guangzhou tomorrow?
⑹This is my beautiful school which[为什么这里不是用where?] is near the famous library
⑺As she was reading the newspaper,Granny fell[为什么这里不是用was falling?] asleep
1.bread 是不可数名词,被rest 修饰时,谓语动词要用单数;
2.楼主留意到后面宾语从句里的pay attention to 了吗?to 是介词,必须带宾语,用what正好做它的宾语,而why 是副词,是不能做宾语的.
3.这里的原因与题2相似.如果用what,它必须要在句子中充当主语或宾语,而后面宾语从句里是不缺这两种成分的,故不能用它.请楼主记住:一旦用what,就必须有个主语或者宾语给它充当.
4.定语从句的谓语动词是have finished,复数形式,故主语也要用复数形式those相一致.Anyone或The one 都是单数.
5.这是个宾语从句.主句用一般现在时,从句要用将来时,句末有tomorrow.
6.这是个定语从句.school 是先行词,从句缺少主语,而关系代词要在从句中做这个主语,只能用which或者that.只有在从句中做地点状语时才用where.
7.fall asleep ,go to sleep 等都是瞬间性动词,表达的是瞬息完成的动作,不能用进行时态.
如再有疑问,敬请垂询,给你参考,
