(1) 动名词作主语往往表示普通的、一般的行为,不定式作主语常表示某次具体的行为。不定式(或不定式短语)作主语时常用“it” 来代替,称为形式主语,真正主语(不定式)放在句尾。Collecting information about children's health is his job.It's necessary to discuss the problem with an experienced teacher.与一位有经验的老师讨论这个问题是有必要的。① It's difficult (important,necessary)for sb. to do...② It's kind (good,friendly,polite,careless,rude,cruel,clever,foolish,brave)of sb. to do...① It's no good (use,fun)doing...② It is a waste of time doing...They stopped to smoke a cigarette.Don't forget to come tomorrow.He forgot turning the light off.Remember to go to the post office after school.Don't you remember seeing the man before?I regret to tell you that you can't pass the examination.I regret disturbing you so long.Please try to finish this work in thirty minutes.Why didn't you try riding a bike to go to school?I meant to give you this book today,but I forgot.Missing this train means waiting for another hour.(1) see,watch,hear,feel,notice,have等动词既可跟不带to的不定式做宾补,也可跟现在分词做宾补。跟不带to的不定式做宾补表事情全过程或一次性动作;跟现在分词表主动或正在进行。I heard her sing an English song just now.I heard her singing an English song when I passed by her room yesterday.(1) 语态上不同:现在分词表示主动的意思,而过去分词多由及物动词变来,表示被动的意思。(2) 时间关系上不同:一般说来,现在分词所表示的动作往往正在进行,而过去分词所表示的动作,往往已经完成。“have+sb. (宾语)+do sth. (宾语补足语)”意为“让/叫/使某人做某事”。此结构中的 have是使役动词,sb.作宾语,其后的do sth.是省去to的动词不定式作宾语补足语。I'll have someone repair the bike for you.“have+sb. /sth. (宾语)+现在分词(宾语补足语)”意为“叫/让/使某人一直做某事或让某种情况一直发生”。宾语 sb. /sth.后面用现在分词作宾语补足语,表示宾语与现在分词表示的动作之间为主动关系,且动作正在进行。如:Don't have the dog barking much.“have+sth. (宾语)+过去分词(宾语补足语)”意为“让/叫/使/请别人做某事”。宾语sth.后面用过去分词作宾语补足语,说明sth.与过去分词表示的动作之间是被动关系。have difficulty /trouble/problem/fun//a good time +(in)+doing; spend time (in)doing sth花费时间做某事; make a contribution to doing 为……作贡献;look forward to doing 期待……; prefer doing to doing 比起做……更喜欢做......; 声明:以上图文来源网络,我们尊重原创,文章版权及插图属于原作者。若侵立删复习提纲及知识点汇总
