【正文】 為了把英語(yǔ)學(xué)好，她經(jīng)常多說(shuō)多寫。1. 表目的He came to teach the little girl English. 他來(lái)給這個(gè)小女孩上英語(yǔ)課。附：不定式主動(dòng)被動(dòng)討論A)不定式修飾的名詞或代詞和不定式構(gòu)成邏輯上的主謂關(guān)系時(shí)，不定式往往用主動(dòng)形式. Have you got a key to unlock the door? (A key unlocks the door．) B)不定式和它前面被修飾的名詞或代詞構(gòu)成邏輯上的動(dòng)賓關(guān)系，又和該句主語(yǔ)構(gòu)成邏輯上的主謂關(guān)系時(shí)，不定式常用主動(dòng)形式． I have got a letter to write．( I write letter．) He needs a room to live in．( He lives in a room．) I know what to do．( I do what．) 但這句如改為下列形式，不定式就得用被動(dòng)形式： I know what is to be done. 這是因?yàn)?what is to be done是賓語(yǔ)從句，從句中的主語(yǔ) what是動(dòng)詞 do的動(dòng)作對(duì)象 C)不定式作表語(yǔ)形容詞的狀語(yǔ)，和句中主語(yǔ)構(gòu)成邏輯上的動(dòng)賓關(guān)系時(shí)，不定式多用主動(dòng)形式，這是因?yàn)槿藗兺J(rèn)為形容詞后省去了 for one或 for people．例如： He is hard to talk to．( to talk to him．) The book is difficult to understand. ( to understand the book.) 但如果強(qiáng)調(diào)句中的受事者時(shí)，亦可用不定式被動(dòng)式，例如： The handwriting is very difficult to be read. The box is too heavy to be lifted． D)在 “there十be” 的結(jié)構(gòu)中，當(dāng)說(shuō)話人考慮的是必須有人去完成某件事時(shí)，不定式用主動(dòng)形式，如果說(shuō)話人強(qiáng)調(diào)的是事情本身必須完成，則用被動(dòng)形式． There is a lot of work to do. ( Somebody has to do the work．) There is a lot of work to be done． ( The work has to be done.) 請(qǐng)注意下面兩個(gè)句子的含義是不同的： There is nothing to do. 意為無(wú)事可做，感到十分乏味． There is nothing to be done．意為某東西壞了，無(wú)法使之恢復(fù)正常．(3) 不定式作定語(yǔ)時(shí)，一般可轉(zhuǎn)換為定語(yǔ)從句。I want to borrow a piece of paper to write on. 我想借張紙寫字。This is the best room for you to live in. 這是最適合你住的房間。I have something important to do. 我有些重要的事要做。）She is the last to e. 她是最后一個(gè)到的。I have a lot of work to do. 我有許多事情要做。（二）不定式作形容詞的用法——作定語(yǔ)1. 不定式有時(shí)起形容詞作用修飾名詞或代詞，在句中擔(dān)任定語(yǔ)。Will you please help me (to) take this suitcase?如：I saw him e in. 我看見他進(jìn)來(lái)了。(2) 感官動(dòng)詞后面還可用現(xiàn)在分詞作賓語(yǔ)。I was made to do a lot of homework yesterday. 我昨天被要求做很多家庭作業(yè)。It made me feel thirsty. 這東西讓我感到口渴。注意：重點(diǎn)記憶(1) 有一些表示感官的動(dòng)詞，如see, hear, watch, feel, notice和某些使役動(dòng)詞，如let, make, have等，其后跟不定式作賓語(yǔ)補(bǔ)足語(yǔ)時(shí),不定式通常不帶to.He saw Li Ping e into the classroom. 他看見李平走近了教室。He reminded me to lock the door when I left. 他提醒我離開時(shí)鎖上門。She advised him to do so. 她勸他這么做。4. 做賓語(yǔ)補(bǔ)足語(yǔ)She asked me to speak
