(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. Is ________ necessary to plete the design before National Day? A. this B. that C. it D. he 2. When and where to build the new factory _______ yet． A．is not decided B．a(chǎn)re not decided C．has not decided D．have not decided 2.作賓語(yǔ) A．動(dòng)詞后直接不定式作賓語(yǔ)的動(dòng)詞有許多，如want, decide, intend, fail, wish, export, pretend, choose等等。 I mean to go there at once. 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. Hes a strange man. We found ________ difficult to work with him. A. us B. it C. him D. you 3． 作表語(yǔ) 動(dòng)詞不定式作表語(yǔ)，一是主語(yǔ)由不定式充當(dāng)；二是主語(yǔ)由抽象名詞充當(dāng)。 To teach is to learn. The best way to improve your English is to join an English club. 【趁熱打鐵】The purpose of the new technologies is to make life easier,______ it more difficult. 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.
