接不定詞的動詞

很多動詞都可以接不定式的動詞,本頁上列出的所有動詞,都會在接不定詞時使用帶 to 的不定詞。而標上星號的動詞也可以接 that 子句,如例句所示。而標上兩個星號的動詞,則是在主要動詞的主詞是「it」時,只能接 that 子句。

接不定詞的動詞

afford agree* aim appear** arrange* bother care
claim* condescend consent decide* demand* determine* endeavour
fail guarantee* happen* hasten have (= 必須) hesitate hope*
learn long manage offer prepare pretend* proceed
promise* propose prove (= 原來是) refuse resolve* seek seem**
strive swear* tend threaten* trouble undertake volunteer
vow*          
舉例
  • I hope to see you next week.
  • I hope that I'll see you next week.
  • He claimed to be an expert.
  • He claimed that she was an expert.
  • I managed to reach the top of the hill.
  • Would you care to swim?
舉例
  • It appeared that no-one had locked the door.
  • He appeared to be lost.
  • It seems that she is running late.
  • She seems to be running late.

接名詞+不定詞的動詞

accustom aid appoint assist cause challenge command*
defy direct* drive empower enable encourage entice
entitle entreat force get implore* incite induce
inspire instruct* invite lead leave (= 托付) oblige order*
persuade* press prompt provoke remind* require* stimulate
summon teach tell tempt trust* warn*  
舉例
  • The professor challenged his students to argue with his theory.
  • This law empowers the government to charge higher taxes.
  • You can't force me to do something I don't agree with.
  • I invited the new student to have dinner with me.
  • What inspired you to write this poem?
在 that 子句前沒有名詞的動詞

當特定動詞接的是 that 子句時,縱使不定詞前有名詞,that 子句前都不會有名詞。這種情況用在 command、direct、entreat、implore、order、require、trust 等動詞。

舉例
  • I trust you to tell the truth.
  • I trust that you are telling the truth.
  • The general commanded his men to surrender.
  • The general commanded that his men surrender.
that 子句前有名詞的動詞

接在動詞後的 that 子句需要在子句前加名詞,就如不定詞前一樣。如 persuade 和 remind 會有這種情況。

舉例
  • You can't persuade people to buy small cars.
  • You can't persuade people that small cars are better.
  • He reminded me to take my notebook to school.
  • He reminded me that I would need my notebook.
在 that 子句前有名詞(也可不加)的動詞

最後一組動詞,在接 that 子句時可選擇在子句前加名詞。這種情況用在 instruct、teach、warn 等動詞上。

舉例
  • She taught her students to appreciate poetry.
  • She taught her students that poetry was valuable.
  • She taught that poetry was valuable.

接不定詞或接名詞+不定詞的動詞

ask* beg* choose dare desire* elect expect*
help mean* (=意圖) request* want wish*    
舉例
  • I asked him to show me the book.
  • I asked to see the book.
  • She helped me to put away the dishes.
  • She helped to put away the dishes.
  • We expect you to do your best in the exam.
  • We expect to do well on our exams.
  • Do you want to go to the beach?
  • Do you want me to go with you to the beach?
dare 的用法

在否定句和疑問句中,只要兩個動詞的主詞相同,不定詞有沒有 to 都可行,不過省略 to 的用法比較普遍。如果兩個動詞的主詞不同,就得加 to。

舉例
  • I never dared tell him what happened.
  • Do you dare tell him?
  • Would you dare (to) jump out of a plane?
  • I dare you to tell him the truth.
  • She dared me to jump off the wall.
