参考案 1.After__C__seemed like hours he came out with a bitter smile.
A.ehich B.it C.what D.that
译文: 在似乎几个小时之后他带着痛苦的微笑出来了.
解析:这里由于时间状语从句中缺少主语,所以用what来代替.

A.There;that B.It;that C.There;whether D.It,whether
译文: 鲍勃不可能在这次比赛中得到一等奖.
解析:前面是一个There be 句型结构,意思为做某事是没有可能的.后面是一个同位语从句作为 possibility的同位语,所以用that引导.

3.We agreed to accept__D__they thought was not the best tourist guide.
A.whatever B.whomever C.whichever D.whoever
译文:凡是他们认为不是最好的导游的人,我们都认可.
解析:这里是一个宾语从句,从句中又缺少主语,所以要用主格形式. 而且指代人. 只有whoever适合.

4.In some countries,__B__is called "equality" does not really mean equal rights for all people.
A.which B.what C.that D.one
译文:在一些国家,一切被称为平等的并不意味着对所有的人来说都有平等的权利.
解析:同样考查主语从句中缺少主语用what代替这一情况.

A.why it does B.what it does C.what it is D.why it is
译文:当我竭力去弄明白究竟是什么妨碍了如此多的美国人正如人们所预料的那样,似乎在我面前有两个原因.
解析:宾语从句中含有一个强调句型,强调what,在句中作主语.

6.By success I don't realize__A__to start and run a company.
A.what it takes B.what takes it C.what they take D.what takes them
译文:通过获得成功,我没有意识到启动和经营一家公司要花费些什么.
解析:宾语从句中跟了一个句型,it takes sb some time /some money to do sth . 这里缺少一个直接宾语some time /some money ,所以用what来代替.
