【正文】 roblem of which to select as his successor was quickly disposed of.5. 不定式的“too+形容詞或副詞+to do sth.”和 “too+形容詞或副詞+for sb/ sth +to do sth.”結(jié)構(gòu)。This pair of trousers is too dirty for him to wear. 這條褲子太臟了，他不會(huì)穿他的。He is too tired. He can’t go any further.→He is too tired to go any further. 他太累了，再也走不動(dòng)了。The box is very heavy. She couldn’t carry it.→The box is too heavy for her to carry. 這個(gè)箱子太重了，她搬不動(dòng)。(2) 這兩種句型還可用so…that…(如此……以至于)結(jié)構(gòu)來連接,構(gòu)成狀語從句.He is so tired that he can’t go any further.The box is so heavy that he couldn’t carry it.He is old enough to join the army. 他到參軍的年齡了。這種結(jié)構(gòu)可跟 “too…to…”結(jié)構(gòu)進(jìn)行句型互換?！鶷his question was not easy enough for everybody in our class to answer.這個(gè)問題不太容易，我們班的所有人都回答不上來。四、省略動(dòng)詞不定式符號(hào)to的幾種情況1. had better…/ Why not…? / Will you please…?/ Shall we…? / Let…等句型后接動(dòng)詞原形。3. help后接動(dòng)詞不定式作賓補(bǔ)時(shí)的to可省也可不省。如：I would rather stay at home than go for a walk. 我寧愿呆在家里而不愿去散步。與另外文檔矛盾，需證實(shí)(1) —Will you join me in a walk? 你愿意和我一塊兒去散步嗎？—I’ll be glad to. 我愿意。我盡力了，但沒找到。 I am glad to see you. 不定式動(dòng)作與句子的謂語動(dòng)詞同時(shí)進(jìn)行。（三）不定式的完成式1）發(fā)生在謂語動(dòng)詞的動(dòng)作或狀態(tài)前，常接不定式完成式的動(dòng)詞有 appear to have done seem to have done happen to(碰巧 have done be said to have done, be reported to have done be believed to have done be known to have done be thought to have done be sorry to have done be likely(可能） to have done等. 還可+to have been done/to have been doing(表一直持續(xù)到..,，可能還要繼續(xù)下去）如They seemed to have known each other for a long time. She is said to have learned four foreign languages. （2）特殊的幾個(gè)動(dòng)詞+to have done表示過去沒有實(shí)現(xiàn)的期待或計(jì)劃 hope to have done（表遺憾，實(shí)際沒做成”希望做過什么事，而實(shí)際沒有）） promise to have done（承諾去做什么，而實(shí)際沒有） want to have done wish to have done expect to have done plan to have done should/would like to have done （表未能實(shí)現(xiàn)的愿望） 如，He wanted to have met you at the airport, but he didn’t get there in time. 沒接成。I should/would like to have given her the gift. 沒送成。 （復(fù)習(xí)，以上是可以接to do的，意思與+to have done不一樣）總之：（1）不定式一般表將來的目的或結(jié)果。 （3）不定式to的省略形式要記住 (4)那些是主動(dòng)表被動(dòng)的要記住 （5）實(shí)在不行就多讀，把他讀出語感16
