【正文】 1)I don’t know what to try next. ()(作賓語) 2)Where to go is not decided yet.(作主語) 。要注意的是，why后面的不定式不帶to。如： also probably a good idea for parents to allow teenagers to study in groups during the evening. () are terrible places for animals to live.()八、帶疑問詞的不定式短語 動詞不定式前面可以帶疑問代詞what, which, who或疑問副詞how, when, where, why等。for前面的形容詞是dangerous, difficult, easy, hard, heavy, important, interesting, necessary等，一般說明不定式動作的特性，不說明人的特性。不定式復(fù)合結(jié)構(gòu)的介詞用for還是of，主要決定于前面形容詞的性質(zhì)。如： 1)Id like to stay healthy, but to be honest, I only eat food that tastes good.() 2)To begin with, she spoke too quickly, and I couldn’t understand every word. () 七、動詞不定式的復(fù)合結(jié)構(gòu) 動詞不定式的復(fù)合結(jié)構(gòu)是“for / of sb. to do sth.”，for / of引出不定式動作的邏輯主語。 ... the mistakes you made are necessary for you to learn and understand.() 這類句子中的動詞不定式可改為主語。動詞不定式前面的形容詞一般是：cheap, dangerous, difficult, easy, fun, hard, interesting, necessary。如： 1)Then I’m too tired to do well. What should I do?() 2)The room needs to be big enough for three people to live in.() ，常說明前面形容詞的性質(zhì)和特性。 ，多見于“sb.+be+adj.+to do...”結(jié)構(gòu)句中。如： 1)In order not to offend people, learning about language etiquette is just as important as learning grammar or vocabulary.() 2)A group of young people got together to(in order to / so as to) discuss this question. () to do / in order to do / so as to do用作目的狀語，置句末時都可以用，置句首時只用to do / in order to do。如： 1)... they can help you to pare two different products so that you can buy the one you really need.() 2)Using English helps you write quickly. () said, be sure, happen, seem等后面可以接帶to的動詞不定式作主語的補(bǔ)語。一般說來，帶to表間接幫助，不帶to表直接幫助。如： 1)Id invite her to have dinner at my house.() 2)Teenagers should be allowed to choose their own clothes. () 3)Email English is supposed to be used on mobile phones.() ，在主動語態(tài)句里不帶to，被動語態(tài)句里帶to時多數(shù)動詞是感官動詞和使役動詞，包括四“看”：look at, observe, see, watch，三“讓”：have, let, make，二“聽”：hear, listen to，一“感覺”：feel，一“注意”：notice。如果不定式是to be done，句子的賓語或主語就是邏輯承受者。如：1)He needs time to do homework.() 2)Is that a good place to hang out？() 3)You want to know the best way to get around the city.() “there be...”句型里，句子的主語是動詞不定式動作的對象，常用主動式。如： 1)When I left home, I had forgotten to bring it with me.() 2)I stopped using them last year. ()四、用作定語 ，不定式與其所修飾的名詞、代詞等存在邏輯的動賓關(guān)系時，用動詞不定式的主動式。stop to do停下來做另外一件事，to do是目的狀語；stop doing停止做、不做當(dāng)前這件事，doing是賓語?！ 。馑疾顒e較大的動詞有forget, remember等。如： 1)Then I started to watch Englishlanguage TV.() 2)I’m beginning
