2022年准备参加河南专升本考试的考生请注意,下面库课李老师给考生整理了河南专升本英语语法非谓语动词,准备参加考试的考生可在考前进行备考。
非谓语中的特殊情况
省去 to 的不定式
①would rather do sth 宁愿做某事 had better do sth 最好做某事
②Why/Why not do sth 为什么做/为什么不做某事
【例】 him do this job by himself?(2007)
A. Why don’t let B. Why not letting C. Why not let D. Why you not to let
【解析】C.固定句式:why not do sth? 故选 C。为什么不让他单独做这份工作呢?
③help 后可带 to,也可不带 to 如;help sb. (to) do sth. 帮助某人做某事
④but 和 except 后。
but 和 except 前出现实义动词 do 时,后面出现的不定式不带 to。即“有 do 无 to, 无 do 有 to)
比较: He wants to do nothing but go out.他只想出去玩。
He wants to believe anything but to take the medicine.除了吃这药,他什么都信。
【例】Missing the last bus, I could do nothing but in the village for the night.
A. staying B. stay C. to stay D. stayed
【解析】B。but 原则“有 do 无 to, 无 do 有 to”,故选 B。错过了最后一般公交车,我没事可做只能在那个小镇里呆上一晚。
带 to 的动词不定式
不定式的特殊句型 too...to do sth ... 太......而不能......
…enough to do sth ...足够....而能够.....
例: He is too excited to speak. 他太激动了,说不出话来。
I work hard enough to get a promotion. 我工作足够努力而能够得到提拔。主动表被动的情况:
sth need/want/require doing=sth need/want/require to be done 某事需要被…
sth be worth doing 某事是值得被做的
【例】The room is quite neat, and it [2011]
A.doesn ‘t need to cleaning B.needn’t to cleaning C.doesn’t need cleaning D.needn’t cleaning
【解析】C, 在这里,need 做实意动词,否定需要借助助动词,排除 B,D,又因为need 后接doing 或者to be done,
故可选出正确答案。
分词做插入语,其结构是固定的,例如:
Generally speaking(一般说来) Talking of/Speaking of(说道) Strictly speaking(严格的说) Judging from(从…判断) All things considered(从整体看来)
Taking all things considered(全面看来)
