英语语法专项:动词不定式用法概括及练习答案
动词不定式用法概括
动词不定式没有人称和数的变化, 在句中不可以独立作谓语。 但动词不定式具出名词、 形容词和副词特色, 在句中能够作主语、 宾语、宾语补足语、 定语、表语和状语等多种成分。 此外,动词不定式拥有动词特色, 能够有自己的宾语和状语, 构成动词不定式短语。 动词不定式的一定形式是 to+do;其否认形式是 not to+ do。 1.作主语
能够直接作主语。如: 但在英语中,常用
To seeis to believe.
it 作形式主语,真实的主语即动词不定式放在后边。如:
It's wrong to play tricks on other people.
It's our duty to keep our environment clean and tidy .( Lesson 10). 点击规律: 动词不定式在句中作主语时, 2.作宾语 attempt 妄图
常放在 It is + adj.(形容词) + to do sth.或 It is +
n.(名词)+ to do sth.句型中, it 仅作形式主语。
a.以下动词只好 to do 作宾语。 安排 mean 意欲,打算
enable 能够 neglect 忽略 afford 负担得起
begin 开始
expect 希望
demand 要求 long 盼望 arrange 显得 determine 决 need 需要 agree 同
appear 仿佛,
定 manage 想法 cease停止 hate 仇恨,憎恶 意 desire 梦想
love 爱 swear 起誓
pretend 假装 ask 问
volunteer 志愿 wish 希望 bear 承受 endeavor 努
忘记 prefer 喜爱,宁 力 offer 供给 beg 恳求 fail 不可以 plan 计划 bother 搅乱;烦忧 forget
decide 决定 learn 学习 regret 对不起,遗憾
愿 care 关怀,喜爱 happen刚巧 prepare 准备 choose 选择 hesitate 踌躇 profess 表示 claim 要求 hope 希望 promise 许诺,同意 承接 want 想要 intend 想要 refuse拒绝 偏向 propose 建议 seek 找,寻找 try 试图
start 开始 undertake
decide 决定 learn 学习 contrive 想法,图谋 incline 有
b. love, like ,begin, start, hate , prefer 等词后边能够接不定式。 点击规律:上述动词后边除接不定式外,还能够接动名词,意思无很大差别。
提示板: like doing 指常常性动作,而 like to do 指一次性的动作。如:
I like swimming , but I don't like to swim now.我喜爱游泳,但我此刻不想游。 c.stop, forget , remember, go on , try 等词或短语后边能够接不定式。 点击规律:上述动词后边接不定式和接动名词意思大不同样。 1) stop to do sth.:停止一件事,去做另一件事。 stop doing sth.:停止正在做的事。
例 句 : When the teacher came in , the students stopped talking ; when he came out , the students stopped to talk .
当老师走进来时,学生们停止说话;当老师走出去时,学生们又开始说话。
2)思虑: forget ,remember,go on,try 等词或短语后边接不定式和动名词用法有何差别?d.在 find / feel +it + adj.+ to do sth.句型中, it 是形式宾语,真实的宾语是后边的动词不定式。如:
The man downstairs found it difficult to get to sleep. I feel it easy to recite the text .
点击规律: 某些动词或短语后边既能够接动词不定式作宾语, 法上的差别能够经过造句子加以划分,如上边 3.作宾语补足语
a.下边的动词要求不定式做宾补:动词
+宾语 +动词不定式
announce
ask 要求,邀请 get 请,获得 prompt 促进 allow 同意 forbid 严禁 prefer 喜爱,情愿
stop 例句。
又可接动名词作宾语, 两者用
