【結論1】
①only＋ to do 表示意想不到的結果。
②doing sth. 與謂語動詞同時發生的動作(主動關系)
③being ＋p.p. 強調與謂語動詞同時發生的被動動作(“因為正在被……”)
④done已經發生的被動動作
⑤having done先于謂語動詞發生的動作(主動關系)
⑥having been done 先于謂語動詞發生的動作(被動關系)
【翻譯句子】
(22) he worked deep into the night, preparing a speech for the president. (worked與preparing同時發生)
他為總統準備演說，工作到深夜。
(23) i got up very early this morning to prepare breakfast for my family. (got up先，prepare breakfast后)
我今天早上起床很早給我的家人準備早餐。
【結論2】不定式“to do sth. ”作目的和結果狀語時總是在謂語動詞后發生，而分詞一般式 “doing sth.”作狀語時總是與謂語動詞同時或幾乎同時發生。
【翻譯句子】
(24) she is so kind as to help me. ＝ she is so kind that she helps me.
她和善地來幫我。
(25) she is such a kind girl as to help me. ＝ she is such a kind girl that she helps me.
她是一個和善的女孩，常來幫我。
【結論3】so ＋ adj. / adv.＋ as to do或such＋(a / an)＋adj. ＋ n. ＋ as to do, 可以轉化為so …that 或such… that 引導的結果狀語從句。
【疑難1】
too…to do表示肯定的情況
i'm only too pleased to help you.
我很高興能幫助你。
one is never too old to learn. 活到老，學到老。 【疑難剖析1】①當only too和 all too與動詞不定式連用時，表示肯定意義。
②too ready (anxious，eager, glad, willing)＋to do，其后的動詞不定式具有肯定意義。
③never (not)＋too…to…句型為“不會太……所以能……”之意。
【疑難2】
seating himself / seated / sitting in the room, he is absorbed in reading.
