中考網(wǎng)整理了關(guān)于2022年中考英語考點:動詞不定式,希望對同學(xué)們有所幫助,僅供參考。
動詞不定式:to + 動詞原形(在某些情況下可以不帶to )。(沒有人稱和數(shù)的變化,可以有自己的賓語和狀語,可以有時態(tài)和語態(tài)的變化)
○1 一般式:主動語態(tài):to do , 被動語態(tài):to be + 動詞過去分詞 (表示動作或狀態(tài)與謂語動詞的動作或狀態(tài)同時發(fā)生或之后發(fā)生)
○2 進行式:主動語態(tài):to be doing , 被動語態(tài):無 (表示動作或狀態(tài)與謂語動詞的動作或狀態(tài)同時發(fā)生)
○3 完成式:主動語態(tài):to have +動詞過去分詞,被動語態(tài):to have been +動詞過去分詞 (表示動作或狀態(tài)在謂語動作之前就發(fā)生)
○4 用法:
A. 作主語:To learn a foreign language is not easy . = It's not easy to learn a foreign language .
B. 作表語:The most important thing is to finish the work on time .
C. 作賓語:
a. 動詞+to do . He decided to buy a new watch . (agree, choose, want, hope, like, wish, learn, love, plan, try, start, afford …)
b. 動詞+疑問詞+to do I don't know where to put the bike .
c. 動詞+形式賓語(it)+賓補+to do I find it important to learn a second foreign language .
D. 作補語:
a. 動詞+賓語+to do Tom asked me to show him the new shoes . (tell, wish, ask, want, like, beg, invite, allow, encourage…)
b. 動詞+賓語+不帶to的動詞 He often saw Tom play football .(see, hear, feel, watch, notice, have, make, let…)
E. 作狀語:
a. 表示目的:He went to Guangzhou to see his sons . He got up early in order to catch the first bus .
b. 表示結(jié)果:He is too tired to walk any farther . They aren't old enough to go to school .
c. 表示原因:He is sorry to hear that . I am glad to see you .
F.作定語: I have something to tell you . I want to buy something to eat .
○5 動詞不定式to 的省略:
A. 在感官動詞feel, hear, see, watch, notice 及使役動詞have, let, make等后面要省to,但在變被動語態(tài)時要還原不定式to。
I often saw him go out of the room .-------- He was often seen to go out of the room by me .
B.在had better, would rather, do nothing but等后面常省to。
○6 動詞不定式的否定形式:not + to do ,有時也可以用-never + to do 結(jié)構(gòu)。
