1.—I telephoned him twice and I couldn't get through.
—I think that the line might have been out of order,__?
A.don't you B.do you C.wasn't it D.hadn't it
我的疑问是为什么不选D?前面第一句说我没有打通,是一般过去时,故第二句电话不在线发生在没有打通(telephoned )之前,过去的过去应该是过去完成时吧?为什么还要用一般过去时?
2.The minute I opened the window,___.
A.in a sparrow flew B.flew in a sparrow C.did a sparrow fly in D.in flew a sparrow
3.—I don't konw why Tom was absent from yesterday's meeting.
—He must have been sick,___?
A.isn't he B.didn't he C.wasn't he D.mustn't he
我的疑问是为什么不选B?
4.The law in almost all states used to require stores to close on Sunday,but now in most states,it no longer__.
A.is B.dose C.did D.has
5.— I'm sorry.That wasn't of much help.
—Oh,___.As a matter of fact,it was most helpfull.
A.sure it was B.it doesn't matter C.of course D.thanks anyway
我的疑问是为什么不选C?
1、 注意题目的谓语动词,从句谓语是have been,也就是be,而不是have,这题的关键就在这儿.举个例子, You have two apples,haven't you?~~~ You have been to Beijing,aren't you? 根据谓语动词是be的话,答案很容易就选C了.
2、英语表达当中,为了生动,有时把表地点、方位的副词,如up/down/out/away/in等放在句首,同时把谓语动词放在主语之前.若主语为人称代词,主语和谓语动词的位置不变,只将副词放在句首.举个例子,Out rushed the girl.首先还原成正常句为 A sparrow flew in the minute I opened the window.其中“the minute I opened the window”相当于插入语,去掉的话句子仍可成立.就是 A sparrow flew in.倒装一下就是 In flew a sparrow.
3、这题和第一题一样,注意题目的谓语动词是 been!
4、在大多数州,法律曾要求商店在周日关门.但是现在,它不再(这么要求了). 其实这题和1、3题差不多.主语 the law;插入语“in almost all states ”可忽略;谓语 require(use to do sth,过去常常做某事);宾语 stores.所以did 就是指代 require
5、对不起,那样并不起效.~~~ 噢,它(起效).事实上,它非常有用.B项为 没关系;C项为当然,意思就是当然没起到效果,显然和题意不合;D项为无论如何很感谢.A项则很好的针对了问者的提问.
还是希望能帮助到你!O(∩_∩)O~
