大家好,小跳來為大家解答以上的問題 。英語動詞不定式視頻講解 ， 關于英語動詞不定式這個很多人還不知道,現在讓我們一起來看看吧！
1、一、不定式的基本形式: to＋動詞原形,有時可以省略to.二、 動詞不定式的特點: （1）沒有人稱和數的變化,在句子中不能作謂語.（2）動詞不定式仍保留動詞的特點,可以有自己的賓語和狀語.動詞不定式同它的賓語或狀語可構成動詞不定式短語.如: to read a book; to sing at the party.（3）動詞不定式具有名詞、形容詞和副詞的特征,因此,在句中可以作主語、表語、賓語、賓語補足語、定語和狀語.三、動詞不定式作賓語.即不定式直接跟在謂語動詞后,是謂語動詞涉及的直接對象.如果沒有這個不定式,這個句子的意思就讓人難以理解. 能直接帶不定式作賓語的及物動詞主要有: want, like , love , need , try , ask , learn , begin , start , forget , remember, hope , wish , agree, choose , fail , refuse , decide , afford , offer , make sure , take turns , would like , plan , hate , try one’s best 等.四、動詞不定式作賓語補足語. 能用動詞不定式作賓語補足語的動詞有: ask , tell , get , order , would like , want , teach , show , allow , encourage , warn , wish , invite ,help等.五、動詞不定式作狀語: 即不定式直接跟在謂語動詞后,僅對謂語動詞起一個補充說明的作用.如果沒有它,句子仍然意思完整,它不象作賓語那樣,與謂語動詞有著密切的關系.（1）表示目的: The doctor came to operate on her. He has gone to town to do some shopping. I sat down to have a rest. He stopped to have a look. He rushed into the room to save the girl. The moved away the stone to let the traffic go. He got up to catch the train.（2）表示結果: The girl cried only to make her mother angry.（3）表示程度: She is too tired to walk any farther. She is strong enough to carry the heavy box.（4）表示原因: I was surprised to read the news.能帶不定式作狀語的形容詞有: glad , happy , pleased , angry , clever , careful , surprised , lucky ,ready ,sorry, amazed , afraid ,sad , unhappy , sure , free ,kind, nice , worried , easy , hard六、不定式作定語: 動詞不定式作定語,一般要放在被修飾詞的后面,不定式與所修飾的詞構成動賓關系. We have lots of work to do. Would you like something to drink? I want to get something to read during my holiday. That’s a difficult question to answer.【注意】如果動詞不定式是不及物動詞,后面就應有必要的介詞. 如: He is looking for a room to live in. Give me a piece of paper to write on. He has nothing to worry about. There is not enough space to stand in on the earth.. She is a nice person to work with. a place to go to.七、動詞不定式作主語: 如 To learn a foreign language is not easy.在現代英語中,常用it來作形式主語,而把真正的動詞不定式主語放在后面.即句型:“It is＋形容詞＋for （ of） sb. to do sth.”中，當形容詞是kind ，nice。
2、 good，clever，careful。
3、 careless , right , wrong , foolish 等表示人的性格特征時, 用of ; 如果形容詞為difficult , easy , hard, important ,interesting, possible ,necessary 等表示事物的特征時, 用for. It is necessary / important / easy / hard/ possible for us to learn English well. It is very kind /nice / good of you to help me with my English.※ 在句型: 主語＋find / think / feel / make +it +形容詞+ to do sth.中,it為形式賓語.I found it very important to learn English well. I think it easy to learn English well.八、作表語: My job is to teach English. His wish is to become a scientist.九、動詞不定式和疑問詞連用.動詞不定式可以和疑問詞what, which , how , when , where ,who 等連用,構成不定式短語,在句子中作主語、賓語、表語等成分.這時往往可以擴寫成賓語從句; The question is how to use the computer.I don’t know where to go for my holiday =I don’t know where I can go for my holiday.He can’t decide which book to choose.= He can’t decide which book he can choose.I don’t know what I should do next=I don’t know what to do next.十、動詞不定式的否定形式: not to＋動詞原形Tell him not to be late. I will try not to read in bed.十一、動詞不定式省略to的場合:（1）作動詞let, make , have, feel ,hear, see , watch , notice 等的賓語補足語時,動詞不定式不帶to. Let him do the work. He made me work day and night. I saw him fall off the bike.（2）作動詞help的賓語補足語時,動詞不定式可帶to,也可不帶to.He didn’t help me（to）mend the bike. You have helped ( to ) protect our environment.（3）在助動詞和一些情態動詞如will , would , shall , should , can , could , may , might , must , do , does , did , didn’t , don’t , doesn’t 等的后面,用動詞原形,即動詞不定式不帶to.Will you help me? He doesn’t live here. It might rain . You must finish your homework on time.（4）在why not…? , had better , would rather 等的后面也跟不帶to的動詞不定式.（原形）Why not buy a dictionary? You had better （not）stay at home. I would rather go early.（5）在第二個不定式前一般不帶to. I would like to lie down and go to sleep.Do you want to eat now or wait till later?※ 在下列答語中, to不能省略: －Will you join me in a walk?－I will be glad to.－Will you go swimming with me this afternoon?－I would love to.－Used he work in the factory?－Yes , he used to .Exercises:1. We must find a person （做這項工作）2. In my family, my mother is always the first one （起床）3. Do you have （什么問題要問）?4. There are （許多重要事情要談）5. This book is （不容易理解）6.He was too excited （說不出話來）7.
