语法与惯用法知识点:不用人作主语的习惯 【导语】英语语法让很多学生都头疼,因为复杂难懂的句式和词组有时难以记忆。 英语网为大家整理了英语语法大全,希望对同学们的英语语法学习有所帮助。 更多内容尽在英语网。 汉语的看书有两层含义:
请看下面的句子,答案是哪个? 原因是什么?
He is __________ to win the match.
A. possible B. difficult C. sure D. easy
此题应选C。 其余几项不能选为答案,是因为它们在通常情况下,easy, difficulty, possible, impossible, necessary 等形容词后接不定式时,通常不以人作主语。 请再看实例:
他可能会赢得这场遥。
误:He is possible to win the match.
正:It is possible for him to win the match.
我很难按时完成它。
误:Im difficult to finish it in time.
正:Its difficult for me to finish it in time.
他可以轻而易举地把它干好。
误:Hes easy to do it well.
正:Its easy for him to do it well.
他遥能遥。
误:He is impossible to succeed.
正:It is impossible for him to succeed.
他有必要买台电脑。
误:He is necessary to buy a computer.
正:It is necessary for him to buy a computer.
对于以上结构,有些形容词有时也可用人作主语,但要注意,此时这个主语必须是其后不定式的逻辑宾语。 如:
他很容易(难)相处。
正:Hes easy (difficult) to get along with.
正:Its easy (difficult) to get along with him.
