【正文】 money and no place to live. 注②當作定語的不定式所修飾的名詞或代詞是不定式動作的承受者時，不定式既可以用主動語態(tài)，也可用被動語態(tài)，但其含義有所不同．試比較： A) Have you anything to send? 你有什么東西要寄嗎? (不定式 to send的動作執(zhí)行者是 you) B) Have you anything to be sent? 你有什么要(我或別人)寄的東西嗎? (不定式 to be sent的動作執(zhí)行者是已被省略的 me或難點someone else) 5)作狀語，表示目的、原因、結(jié)果或條件．例如： I came here to see you．(目的) We were very excited to hear the news．(原因) He hurried to the school to find nobody there．(結(jié)果)so + adj. / adv. + as to dosuch + adj. + n. +as to do…adj. / adv.+ enough + to dotoo + adv. / adj. +to do:太...而不能....。Will you please help me (to) take this suitcase?非謂語動詞用法詳解動詞的非謂語形式有三種：不定式、動名詞和分詞(一)不定式 不定式由“ to十動詞原形”構成，其否定形式是“ not to do”．不定式可以帶賓語或狀語構成不定式短語，沒有人稱和數(shù)的變化，但有時態(tài)和語態(tài)的變化．不定式可作主語、賓語、狀語、表語和定語，但不能單獨作謂語．不定式的邏輯主語有時用“ for十名詞或代詞賓格”構成． 1．不定式的用法： l)作主語．不定式短語作主語時，往往放在謂語之后，用 it作形式主語．例如： To see is to believe． It is right to give up smoking． 2)作賓語．不定式短語作賓語時，如果還帶有賓語補足語。往往把不定式賓語放在賓語補足語之后，而用 it作形式賓語．例如： He wanted to go． I find it interesting to study work with him. 3)作賓語補足語．例如： He asked me to do the work with him. 注意 ：在 feel，hear，listen to，look at，notice, observe，see，watch，have, let，make等詞后的補足語中，不定式不帶 to．但是這些句子如果變成被動結(jié)構時，就必須帶 to．例如 I often hear him sing the song． He is often heard to sing the song． 注意：不定式動詞在介詞 but，except，besides后面時，如果這些介詞之前有行為動詞 do的各種形式，那么，這些介詞后的不定式不帶 to，否則要帶 to．如： She could do nothing but cry. What do you like to do besides swim? I have no choice but to go． 動詞help之后，帶to或不帶to都可以。 請你幫我提一下這個衣箱好嗎？She often helps her mother (to) clean their house. 她經(jīng)常幫助她媽媽打掃房子。非常...He was so foolish as to believe it. = He was such a fool as to believe it. = He was foolish enough to believe it.
