反身代詞的用法

　　可以用來做賓語：He hurt himself when he fell.

　　可以用來做表語：He is not quite himself today. (他今天有些不舒服)

　　反身代詞經(jīng)常放在名詞或者代名詞的后面來進(jìn)行強(qiáng)調(diào)， 表示“親自”的意思

　　I myself do it.

　　I do it myself.

　　They made the research themselves.

　　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(zhǎng)時(shí))

　　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(hào)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(shí)用who，whom，whose

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

　　在修飾物時(shí)用 which

　　部分狀語從句可以省略，在填空題中時(shí)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(shí)的時(shí)間狀語是for + 一段時(shí)間(已經(jīng)有…時(shí)間了)，和since + 一個(gè)時(shí)間點(diǎn)(自從…以來)的時(shí)候，句中的謂語不能是非延續(xù)性動(dòng)詞(暫短性動(dòng)詞)，如不能說 ：I have borrowed the book for ten days. (錯(cuò)誤：borrow這個(gè)動(dòng)作是發(fā)生在圖書出納臺(tái)上的一次性動(dòng)作，不能延續(xù)，因此不能和for引導(dǎo)的時(shí)間狀語連用)應(yīng)改為：I have kept the book for ten days.

　　這樣的暫短性動(dòng)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(qiáng)調(diào)被提前的部分。
