(2)To master English gives us much help in the study of science. B 不定式或不定式短語(yǔ)作主語(yǔ)時(shí)，常用it作形式主語(yǔ)，構(gòu)成“It is + 形容詞(+for sb.)不定式”結(jié)構(gòu)。 It is impossible for him to give up smoking. 【趁熱打鐵】1.

B.不定式短語(yǔ)作賓語(yǔ)時(shí)，如果還帶有賓語(yǔ)補(bǔ)足語(yǔ)，往往把不定式短語(yǔ)放在賓補(bǔ)之后，而用it作形式賓語(yǔ)。句型為“主語(yǔ)+find (feel, think, believe, consider,etc) +it+形容詞/名詞+to do sth”。 I think it necessary to report the thing to the teacher. I find it interesting to work with him. 【趁熱打鐵】1. She pretended ________ me when I passed by. A. not to see B. not seeing C. to not see D. having not seen 2. —Do you know Mr. Smith? —Yes.

A. not make B. not to make C. not making D. do not make 4． 作賓語(yǔ)補(bǔ)足語(yǔ) 【注意】在感官動(dòng)詞（see, hear, feel, listen to , notice, watch, observe等）和使役動(dòng)詞（let, have， make ）后的補(bǔ)足語(yǔ)中，不定式不帶to。但這類(lèi)句子變成被動(dòng)語(yǔ)態(tài)時(shí)，必須帶to。 I saw him play in the park. →He was seen _______ in the park. 5． 定語(yǔ) 1、不定式與被修飾的名詞往往構(gòu)成邏輯上的關(guān)系。如名詞為不定式的邏輯主語(yǔ)，構(gòu)成主謂關(guān)系； 若名詞為邏輯賓語(yǔ)，則構(gòu)成動(dòng)賓關(guān)系； He is not a man to tell lies. There will not be enough space to stand in on the earth. 2、作定語(yǔ)的不定式與所修飾的名詞之間是動(dòng)賓關(guān)系， 不定式動(dòng)詞又是不及物動(dòng)詞時(shí)，應(yīng)在該動(dòng)詞上加上一個(gè)介詞，如; He has a nice pen to write with. He is looking for a room to live in. 【趁熱打鐵】With a lot of difficult problems ___________ , the newly elected president is having a hard time.
