28.-- English is hard to learn,isn’t it?
-- I don’t think so._____ more words andexpressions,and you will find it easier to read and communicate.
A.Knowing B.Know C.To know D.Known
选B.
解析:祈使句+and+简单句相当于if 引导的肯定的条件句.
Know more words and expressions,and you will find it easier to read and communicate.=
If you know more words andexpressions,and you will find it easier to read and communicate.
祝开心~!
再问: 我想知道为什么不能是 knowing
再答: 如果是knowing,要么就是动名词,要么就是现在分词。动名词,顾名思义,就是做名词试用,一个名词能独立成句吗?如果是现在分词作状语,后面有and就是错的。如果你要用knowing,你要去掉and。 对了,If you know more words andexpressions, and you will find it easier to read and communicate. 这个and要去掉,我为了偷懒把后面一截直接复制了,没注意到,实在抱歉。 重要的是,你到底懂没有?亲~~~
