怎么区别动词非谓语动词的时态?
怎么区别动词非谓语动词的时态?
非谓语动词非谓语动词(不能作谓语用)包括不定式、分词及动名词.
动词不定式1.常用形式:一般主动式to do, 一般被动式to be done
完成主动式to have done, 完成被动式to have been done
进行式to be doing
2.语法功能:可作主语、表语、宾语、宾补、定语和状语(即除谓语之外的各种成
分).例如:
1)主语:To master a foreign language is very important.
2)表语:My job is to drive them to the company every day.
宾补:The teacher advised us to have a rest first.
I didn07t notice them come in.
注:see, hear, watch, notice, have, make, let等动词后作宾补的动词不定式不带to, 但变为被动语态以后(即不定式作主补时)要带to, (其中let sb. do sth. 变为被动式为sb. is let do sth.)
help(帮助)后作宾补的动词不定式可带to,也可不带to. 即help sb.(to)do sth.
定语:不定式位于所修饰的名词,代词之后,如:Who was the first one to set
to the top of the hill yesterday? /He is the man to depend on/to believe in.
6)状语: in order to
A.目的状语:She reads China Daily every day so as to improve her English.to注:in order to 可以位于句首或句中,so as to 不能位于句首.
B.原因状语: I’m glad to see you . 注:这种“be+形容词+不定式”结构,其不定式有时也可视为宾语,如:He is eager to go to college./ She is sure to come here.
C.结果状语:They lived to see the liberation of their home town.他们一直活到见到家乡解放.
△在“too…to…”结构中表“太…结果不能”,如:He is too weak to do the work.
注:too之前如果有only, only too 表“非常”、“很”意,此时不定式不再表否定意,而表肯定意.如:They are only too lucky to go abroad for a visit. 他们很幸运去国外访问.
另外,too后如果是happy, glad之类形容词时,不定式也表肯定意,
