11、abits like these from dominating a teenager s life is essential.(3)To change bad habits is never easy, even with many attempts.(4)After all, it is not easy to break bad habits.以上句子中動(dòng)詞不定式都是作主語(yǔ)。.句(1)和句(4)中it作形式主語(yǔ),真正的主語(yǔ)是后面的動(dòng)詞不定式。Activity 2語(yǔ)法精析一、基本用法動(dòng)詞不定式作主語(yǔ)時(shí)，謂語(yǔ)動(dòng)詞用單數(shù)。To look after these naughty boys is

12、really difficult.照看這些淘氣的男孩真的很難。為了防止頭重腳輕，常用it作形式主語(yǔ)放在句首，作主語(yǔ)的不定式常置于句末。It would be better for you to go there.你還是去那里的好。注意：1 .假設(shè)要說明不定式表示的動(dòng)作的發(fā)出者，要在不定式前加for引起的短語(yǔ)，構(gòu)成“for +名詞(或代詞賓格)+不定式”短語(yǔ)，這一短語(yǔ)被稱為不定式的復(fù)合結(jié)構(gòu)。2.在“It is+。力.+不定式復(fù)合結(jié)構(gòu)”句型中，當(dāng)其中的形容詞是說明邏輯主語(yǔ)的性質(zhì)、品 質(zhì)時(shí)，要由of引出邏輯主語(yǔ)，不能用foro這類形容詞主要有clever, foolish, kind, nice,

14、ell.學(xué)好英語(yǔ)不容易。It is no use asking him for help.向他求助是沒有用的。如果主語(yǔ)用了不定式，表語(yǔ)和賓語(yǔ)也要用不定式；主語(yǔ)用了動(dòng)名詞，表語(yǔ)和賓語(yǔ)也要用動(dòng) 名詞，這在英語(yǔ)中稱為對(duì)稱性，如：To see is to believe. = Seeing is believing.眼見為實(shí)。It is better to stay home than to go out.待在家里比出去要好。.動(dòng)名詞和不定式作主語(yǔ)的不同點(diǎn)不定式作主語(yǔ)常表示具體的某一動(dòng)作；表示泛指或一般的抽象的概念時(shí)，多用動(dòng)名詞。Walking is a good form of exercise f

15、or both the young and the old.散步是一種老少皆宜的很好的 運(yùn)動(dòng)形式。(2)在“It+be+no use(good/help/need等)”之后常用動(dòng)名詞作主語(yǔ)，而少用不定式。It is no use crying over the split milk.覆水難收。It is no help taking this medicine.服用這種藥沒有用。注意：如果該句型中用了 for引出不定式的邏輯主語(yǔ)，就只能用不定式。It is no good for us to do that exercise.我們做那種練習(xí)沒有好處。(3)不定式可以和when, where,

16、how, what, whether等連用，在句子中作主語(yǔ)、賓語(yǔ)和表語(yǔ), 而動(dòng)名詞那么不能。Where to put the box seems hard to decide.很難決定把這個(gè)箱子放在哪里。Whether to do it hasn? t been decided.是否做這件事還沒定下來。達(dá)標(biāo)檢測(cè)I .翻譯句子.被邀請(qǐng)參加瑪麗的生日派對(duì)是很榮幸的事情。It s a great honoui to be invited to Maiy s birthday paity.我們難以在15分鐘內(nèi)寫完這篇作文。It is difficult for us to finish writing
