1.A computer is so useful a machine___we can use everywhere.
A.that B.which C.as D.what
这里不用想那么复杂.其实就一个简单句型: so +形容词+名词/代词+that+句子 .翻译为:如此...以至于...
选A
2.The heavy rain this morning stopped us___the furniture to Wang's house.
A.sending B.to send C.to be sent D.in sending
考查搭配:stop to do sth 停下来去做另一件事
stop doing sth 停止做未完成的事
句子翻译为:今天早上的那场大雨阻碍了我们把家具送到王小姐的家.
显然:这里不可能为"使我们停下来然后去送家具",而应该是"使我们停止送家具"BD可排除.
这里也不可能为被动语态.C可排除.
选A
3.It__that he was__than any other classmate in his class.
A.believed,less bright B.believed,more bright
C.was believed,less bright D.was believed,more bright
考查句型:It is believed that ....=It is said that ...
翻译为:据说....
排除AB
句子翻译为:据说在他的班上他比任何一个同学都要聪明.
按常理:这里应该是赞扬他聪明的,而不是说他比不上别人.
因此排除C
综上:选D
