这类系表结构后不定式要用主动式表被动意义
这类系表结构后不定式要用主动式表被动意义
先看一道题:
This book is difficult __________.
A. to understand B. to be understand C. to understand it D. being understood
此题应选A。容易误选B。从意思上看,本句主语与其后不定式有动宾关系,所以不少考生便误选了不定式的被动式,但是这里有一点特殊之处。
按照英语习惯,由easy,hard,nice,difficult,amusing,interesting,dangerous,impossible,important,pleasant,等形容词构成的系表结构后,接用不定式时,通常要用主动式表示被动含义:
English is not easy to learn. 英语不容易学。
This question is difficult [hard] to answer. 这个问题很难回答。
That bird is impossible to catch. 那只鸟不可能被抓住。
The river is dangerous to swim in. 在这条河里游泳很危险。
Football is interesting to watch. 看踢足球很有意思。
以上结构可以换成用 it 作形式主语的句型:
正:English words are difficult to remember.
正:It is difficult to remember English words.
写那样一本书很容易。
正:Such a book is easy to write.
正:It is easy to write such a book.(www.hxen.net)
