暑假预习 · Unit 2 动词不定式2026-2027学年沪教版九年级上册英语

新沪教牛津九上英语暑假预习 · Unit 2 Unit 2 Great minds · 动词不定式（学生版） ( 囚 语法精讲 ) ą 一、动词不定式的形式肯定式：to + 动词原形 否定式：not to + 动词原形 例：Tell him to come early. / Tell him not to come late. 动词不定式在句中不能作谓语，不随主语人称和数的变化而变化。㐱 二、动词不定式的句法功能 成分 用法 例句 主语 ①位于句首，谓语用单数；②常用it作形式主语 To learn English is important. / It's important to learn English. 表语 放在系动词后，可转换为作主语 My job is to clean the room. = To clean the room is my job. 宾语 作某些动词（want, decide, hope, agree等）的宾语；可用it作形式宾语 I decide to go. / I find it easy to learn English. 宾语 补足语 tell/ask/want/allow/encourage sb. to do; 感官动词和使役动词后省to（被动还原to） She asked me to help. / I saw him go out. / He was seen to go out. 定语 放在被修饰词后面，作后置定语；注意不及物动词加介词 I have a lot of work to do. / I need a pen to write with. 成分 用法 例句 状语 表目的、结果、原因 He went to Beijing to study. / I'm glad to see you. 独立成分 to be honest, to tell you the truth等 To be honest, I don't like it. 㐱 三、常用搭配 疑问词+不定式：what to do, how to go, where to live等，相当于名词 性从句。 too + adj. + to do：太 而不能 adj./adv. + enough + to do：足够 去做 例：He is too young to go to school. / He is old enough to go to school. 㐱 四、不定式符号to的省略 ① 感官动词（feel, hear, listen to, see, watch, notice, look at）和使役动词（let, make, have）后作宾补省to，被动要还原。 ② would rather do than do; had better (not) do; why not do; can't but do。 ③ 并列不定式，第二个及后面的不定式省to。 例：I saw him go out. / He was seen to go out. / We had better stay at home. / I want to visit him and thank him. ( q 易错提醒： ① make him to go x → make him go ✅ （省 to ） ② He was made go x → He was made to go ✅ （被动还原 to ） ③ I don't know what to do it x → what to do ✅ （疑问词 + 不定 式， do 及物时不需要介词） ) Part A：单项选择（本大题共20小题，每小题2分，共40分） 1.
