1、 代詞 代詞可以分為下列九類(lèi)1 人稱(chēng)代詞2 物主代詞3 反身代詞4. 相互代詞5. 指示代詞 6. 疑問(wèn)代詞7. 關(guān)系代詞8. 連接代詞9 不定代詞 一 人稱(chēng)代詞英語(yǔ)中主要有以下這些人稱(chēng)代詞： 數(shù) 格 人稱(chēng) 單數(shù) 復(fù)數(shù) 一 二 三 一 二 三 主格 I you he, she, it we you they 賓格 me you him, her, it us you them 人稱(chēng)代詞做主語(yǔ)時(shí)用主格，做賓語(yǔ)時(shí)用賓格。 在作表語(yǔ)時(shí)，用賓格較多，例如：Who is knocking at the door? - It's me. 但在強(qiáng)調(diào)結(jié)構(gòu)中卻常用主格：It is I that who

2、will love you from beginning to end. 在使用人稱(chēng)代詞時(shí)有下面幾點(diǎn)值得注意： 1）she可以用來(lái)代表國(guó)家，船只，大地，月亮等。 e.g. I think England will do what she promised to do. 2) 在并列的主語(yǔ)中，I總放在最后。e.g. Mary and I will be in charge of the case. You,she and I ,who are all good friends,should love one another from the bottom of our heart forever

3、. 3) 第三人稱(chēng)，男女兩性并用時(shí)，男先女后。e.g. He and she still don't agree to the plan. 二 物主代詞英語(yǔ)中主要有下列這些物主代詞： 類(lèi)型 詞義 我的 你的 他（她，它）的 我們的 你們的 他們的 形容詞性物主代詞 my your His, her, its our your their 名詞性物主代詞 mine yours His, hers, its ours yours theirs 1. 形容詞性的物主代詞只能作定語(yǔ)，如I am going to my home village to see my parents this we

4、ekend. 2. 名詞性的物主代詞可以作：（注：形代具名名代，形代在句中其后必有具體的名詞。） 1) 主語(yǔ) Ours is a big family. 2）賓語(yǔ)The life in your country is quite different from ours. 3）表語(yǔ)Whose dictionary is this? -it's mine. 4） “of +名詞性物主代詞”可用作定語(yǔ) That car of hers is always breaking down.= Her car is . 三 反身代詞 單數(shù) myself 這些詞可用來(lái)：yourself himself

5、 herself Itself 復(fù)數(shù) ourselves yourselves themselves (注：主賓一致的情況下往往用反身代詞充當(dāng)賓語(yǔ)。) 11） 作賓語(yǔ)I can't express myself in English. 2) 作表語(yǔ)I am not quite myself these days. 3）作主語(yǔ)或賓語(yǔ)的同位語(yǔ)The theory itself is all right. 在作同位語(yǔ)時(shí)，自身代詞常譯作“本人”或“親自” They must make investigation themselves.他們必須親自作調(diào)查。 與by oneself較難區(qū)分 by

6、oneself 譯為“一個(gè)人干（不要?jiǎng)e人幫助）” They made the machine all by themselves. 這機(jī)器完全是他們自己制造的。 2自身代詞常和某些動(dòng)詞連用 enjoy oneself, behave oneself(使自己舉止良好),help yourself to sth. 請(qǐng)吃點(diǎn).Come to oneself蘇醒 3常與某些介詞連用 by oneself 一個(gè)人做（不要?jiǎng)e人幫助） for oneself替自己，自己 He has a right to decide for himself. 他有權(quán)自己決定。 in oneself 本身 This is n

7、ot a bad idea in itself. 這主意本身并不錯(cuò)。 to oneself供自己用 She had a room to herself. 她自己住一間房。 四 相互代詞 One another與each other由于表示相互關(guān)系，稱(chēng)為相互代詞，兩者的用法是差不多的。 We can help one another (each other). We are eager to learn from each other. 五 指示代詞 有this, that, these, those. 注意： 1 前面剛提到的東西，英語(yǔ)中常用that (或those)表示。 e.g. We h

8、ave no time to do it. That's our trouble. The umbrella you bought yesterday is cheaper than that I bought a moment ago. 1 Generally speaking,the weather in the south is warmer than that in the north. (注：that指代可單the one，亦可指代抽象的不可數(shù)名詞。) 2. 指下面要談到的事物時(shí)，常用this, 表示。 I want to know this: has John been h

9、ere? 3 those在下面的這種類(lèi)型的句子里常出現(xiàn)，表示人們或東西（后面多有一定定語(yǔ)修飾） Those who learn not only from books but also through practice will succeed. The students in Class 1 are more active than those in Class 2. .(注：those指代可數(shù)名詞的復(fù)數(shù)the ones。) 六 疑問(wèn)代詞 有who, whom, whose, what, which都是來(lái)構(gòu)成特殊問(wèn)句的。Who通常做主語(yǔ)和表語(yǔ)，whom做賓語(yǔ)。 1 what, who 一般來(lái)

10、說(shuō)，what 問(wèn)的是職業(yè)或地位，who問(wèn)的是姓名。 -What was her husband? - He was a lawyer. 比較 - who was her husband? - He was John Smith, the son of a famous writer. 2 which, what Which用于已知情況的選擇，其后可以跟of, 而what用于未知情況的疑問(wèn)，其后不能跟of. What fruit do you like best? Which do you like better, oranges or apples? 3 在以這類(lèi)代詞做主語(yǔ)時(shí)，后面的動(dòng)詞可以用

11、復(fù)數(shù)形式，也可以用單數(shù)形式，要看所代表的人或物是復(fù)數(shù)還是單數(shù)來(lái)決定。e.g. Who live(s) in this room? 如果不清楚代表的東西是復(fù)數(shù)還是單數(shù)，則動(dòng)詞多用單數(shù)形式。 -What's there on the desk? - There're some books on it. 七.連接代詞：疑問(wèn)代詞都可以用作連接代詞，來(lái)引起主語(yǔ)從句，賓語(yǔ)從句和表語(yǔ)從句。（注：不管何種從句我們的原則是“缺什么補(bǔ)什么”且語(yǔ)序要用陳述語(yǔ)序，即引導(dǎo)詞位于句首其后的語(yǔ)序用主謂系結(jié)構(gòu)，that只有引導(dǎo)定語(yǔ)從句才在定從中充當(dāng)句子成分其它任何情況下均不充當(dāng)句子成分，只起引導(dǎo)詞的作用，若“

12、句意完整無(wú)疑問(wèn)”我們用that引導(dǎo)名詞性從句，若含“是否之意又不缺句子成分”用ifwhether引導(dǎo)名從）。 Whether they win or lose is all the same to me. What I really care about is whether it works or not. That china is a great socialist country is well known. The idea that the earth is round is not a new one. I didnt know what had happened until h

13、e told me the news. After 5 hoursdrive,they got to what they thought was the place they had been dreaming of. When will the person who you think is up to the task come to work? How he worked it out is still a secret. 代詞what有時(shí)可以用來(lái)表示the thing which這種意思。 We should never pretend to know what we don'

14、t know. 2 who(m), which, what等可以和ever構(gòu)成合成詞，和前面所提到的疑問(wèn)代詞一樣，引導(dǎo)名從。 whatever=anythingeverything that或any , whichever (=anyone whoanything that)whoever (=anyone who) , whomever (=anyone whom)whosever(anyone whose) 等可用于引導(dǎo)名詞性從句。這類(lèi)引導(dǎo)詞均相當(dāng)于“先行詞關(guān)系代詞”，沒(méi)有疑問(wèn)語(yǔ)氣，但沒(méi)有ever的引導(dǎo)詞which, who等卻依含有疑問(wèn)意味。如： The poor young man i

15、s ready to accept whatever (=any) help he can get. 那個(gè)年青人意愿接受能得到的任何幫助。 Whoever (=Anyone who) comes will be welcome. 任何人來(lái)都?xì)g迎。 This kind of book is of great help to whoever wants to do the job. 你們之中誰(shuí)想要，我就給誰(shuí)。 You should give it back to whosever(anyone whose)name is on the cover of the book. 注：這類(lèi)詞也可引導(dǎo)狀語(yǔ)從

16、句，可用“no matter+疑問(wèn)詞”替換，“no matter+疑問(wèn)詞”只引導(dǎo)讓步狀語(yǔ)從句且用逗號(hào)和主句隔開(kāi)。如： Whoever (=No matter who) you are, you can't pass this way. 不管你是誰(shuí)，你都不能從這里通過(guò). will come to help with my English hasnt been decided.

It is被強(qiáng)調(diào)部分that 該句型是強(qiáng)調(diào)句型。將被強(qiáng)調(diào)的部分放在前面，其它部分置于that 之后。被強(qiáng)調(diào)部分可以是主語(yǔ)，賓語(yǔ)，表語(yǔ)或狀語(yǔ)。強(qiáng)調(diào)的主語(yǔ)如果是人，that 可以由 who 換用。如果把這種句型結(jié)構(gòu)劃掉后，應(yīng)該是一個(gè)完整無(wú)缺的句子。這也是判斷強(qiáng)調(diào)句型與其它從句的方法。 It was about 600 years ago that the first clock with a face and an hour hand was mad

49、e. It was they that（who）cleaned the classroom yesterday. It was in the street that I met her father. 2. It is not until被強(qiáng)調(diào)部分that 該句型也是強(qiáng)調(diào)句型。主要用于強(qiáng)調(diào)時(shí)間狀語(yǔ)，譯成漢語(yǔ) “直到才”，可以說(shuō)是 not until 的強(qiáng)調(diào)形式。 It was not until she took off her dark glasses that I realized she was a famous film star. Not until she took off her

50、 dark glasses did I realize she was a famous film star. I didn't realize she was a famous film star until she took off her dark glasses. 3. It is a pity（a shame ）that 該句型中，that 后的從句一般用虛擬語(yǔ)氣（should動(dòng)詞原形），should 可省去. 表示出乎意料，常譯為“竟然”。沒(méi)有這種意義時(shí)，則不用虛擬語(yǔ)氣。 It is a pity that such a thing（should）happen in you

51、r class. 6 4. It is time（about time , high time）that 該句型中that 后的從句應(yīng)該用虛擬語(yǔ)氣，值得注意的是 常用過(guò)去時(shí)態(tài)表示虛擬. 有時(shí)也用should動(dòng)詞原形，should 不能省。常譯為“早該的時(shí)候了”。 It is time that children should go to bed.
