几道高一英语

Question

1.I don't think he had his supper at the school,----?
A.had he B.did he C.do I D. don't you为什么不是A？
2.I'm sure he must have been sleeping at the moment,----?
A.aren't I B mustn't C.wasn't he D.hasn't he

Answer 1

1 B 主句里出现 i think 之类的，反义疑问句就必须看从句行事，记住就好。我们看到从句中谓语是had，又加上是否定 i don't think 所以反义疑问句中就是 肯定的did he

2 C I'm sure和 I think 一个道理。 must have done 一看就是对过去的一种猜测，其实质就是过去时态。句中不过使用过去进行时，还原过来就是 I'm sure he was sleeping at the moment, wasn't he?
呵呵~~~ 希望你明白了哦……

Answer 2

因为这是反义疑问句，因该对I进行反义，如果要选A，则主句不能用I当主语。i think这种是特殊的句型，记住这个答案就好了。反意疑问句如为简单句可直接用助动词或BE动词进行否定。 如为复合句则主要看主句中的主语，主语是I，反意的对象看从句中主语，但反意是与主句相反.第二题选C
