牢記make possible的三種形式：

　　1. make+名詞+possible;

　　His financial aid makes this trip possible.

　　2. make+possible+名詞(名詞短語較長時)

　　His financial aid makes possible the poor Chinese student’s entering of the world famous university.

　　3. make it possible (for sb.)to do (見形式賓語部分)

　　The father’s hard labor makes it possible for the son to receive better education.

　　定語從句可分為限定性和非限定性兩種，其主要區(qū)別為：

　　1. 非限定性定語從句中，引導(dǎo)詞和先行詞之間需用逗號隔開。

　　2. 非限定性定語從句中，引導(dǎo)詞一般不用that，

　　在修飾人時用who, whom, whose

　　He had three children, all of whom had graduated from college.

　　在修飾物時用 which

　　部分狀語從句可以省略，在填空題中時有出現(xiàn)

　　如：Although defeated, he did not lose heart. (從句中省略了he was)

　　If inFORMed timely, I wouldn’t have missed the meeting. (從句中省略了I were)

　　注意: 當(dāng)現(xiàn)在完成時的時間狀語是for + 一段時間(已經(jīng)有…時間了), 和since + 一個時間點(自從…以來)的時候, 句中的謂語不能是非延續(xù)性動詞(暫短性動詞),

　　如不能說 :I have borrowed the book for ten days. (錯誤: borrow這個動作是發(fā)生在圖書出納臺上的一次性動作, 不能延續(xù), 因此不能和for引導(dǎo)的時間狀語連用)應(yīng)改為: I have kept the book for ten days.

　　這樣的暫短性動詞還有: buy/sell, break, die, graduate, drop等倒裝

　　倒裝句就是將正常的陳述語序加以變化，主要作用是強調(diào)被提前的部分

　　倒裝句可分為全部倒裝和部分倒裝兩種：

　　一、全部倒裝

　　謂語動詞提前至主語之前為全部倒裝，如：　Out came his guest.On the hill stood a little cottage that contained heaps of hay.There lived an elderly lady whose husband died long ago.
