【正文】 5．先行詞被the only, the very修飾時6．句中已經(jīng)有who或which時，為了避免重復(fù)時 told me everything that he knows. the books that you offered has been given out. is the best film that I have ever read. talked about the persons and things that we remembered. is the only man that I want to see. is the man that is making a speech?只用which, who, whom的情況1．在非限制性定語從句中，只能用which指代物，用who/whom指人2．在由“介詞+關(guān)系代詞”引導(dǎo)的定語從句中，只能用which指物，whom指人。They won the game, as we had expected.They won the game, which we hadn’t expected.As is well known, he is a famous film star in the 1980s.IV. 限制性定語從句與非限制性定語從句的區(qū)別：類別語法意義及特征例句限制性定語從句對先行詞起修飾限制作用，如果去掉，主句意思就不完整明確，這種從句與主句的關(guān)系十分密切，寫時不用逗號分開。狀語從句種類連接詞注意點時間狀語when, whenever, while, as, before, after, until, till, by the time, as soon as, hardly…when, no sooner…than, the moment, the minute, immediately, directly, instantly主。從句和主句之間用逗號分開，相當于一個插入語，不能用that引導(dǎo)，關(guān)系代詞做賓語時也不能省略。He has a son, who has gone abroad for further study.I like the person to whom the teacher is talking.Those who respect others are usually respected by others.III. as與which的區(qū)別：定語從句區(qū)別例句限制性定語從句中名詞前有such和the same修飾時，關(guān)系代詞用as,不能用whichHe is not such a fool as he looks.Don’t read such books as you can’t understand. 非限制性定語從句中as和which都可以指代前面整個主句。被修飾的詞叫做先行詞，引導(dǎo)定語從句的詞叫關(guān)系詞，他的作用一是放在先行詞與定語從句中間起了連接作用，二是在從句中擔當一個成分，并與先行詞保持數(shù)的一致。但是有形容詞的性質(zhì)，可以做表語，多表明主語的特征性質(zhì)或者狀態(tài)等，可被very, quite, rather等副詞修飾。動作已經(jīng)完成，多強調(diào)狀態(tài)We found the village greatly changed.IV. 非謂語動詞做定語的區(qū)別：區(qū)別舉例不定式與被修飾詞往往有動賓關(guān)系，一般式表示將來，進行式表示與謂語動作同時發(fā)生，完成式表示在謂語動詞之前發(fā)生I have a lot of papers to type.I have a lot of papers to be typed.動名詞通常指被修飾詞的用途，無邏輯上的任何關(guān)系Shall we go to the swimming pool?現(xiàn)在分詞與被修飾詞之間是主謂關(guān)系，表示動作與謂語動作同時發(fā)生the boiling water / the boiled waterthe developing country/the developed countrythe falling leaves / the fallen leaves過去分詞與被修飾詞之間是被動關(guān)系，表示動作發(fā)生在謂語動作之前，現(xiàn)已經(jīng)完成V. 非謂語動詞做主語和表語的區(qū)別：區(qū)別舉例不定式多表示一個特定的具體的將來的動作，做主語時可以借助于it把不定式移到句子后面。其形式為：needn’t/daren’t do；Need/dare…do…?做實義動詞時可用于肯定句，否定句和疑問句。Be able to有更多的時態(tài)。He may not be at home. / They might have finished their task. 3. can和could“可能”，could表示可疑的可能性，不及can’t語氣強，用于肯定、否定、疑問句中。must + do(be)是推測現(xiàn)在存在的一般狀態(tài)進行；must + be doing 推測可能正在進行的事情；must +have done是推測可能已經(jīng)發(fā)生過的事情。4. 一般將來時的表達方式：將來時用法例句1will/shall+動詞原形表示將來發(fā)生的動作或存在的狀態(tài)My sister will be ten next year.2be going to+動詞原形含有“打算，計劃，即將”做某事，或表示很有可能要發(fā)生某事It’s going to clear up.We’re going to have a party tonight.3be + doing 進行時表示將來go, e, start, move, leave, arrive等詞可用進行時表示按計劃即將發(fā)生的動作He is moving to the south.Are they leaving for Europe? 4be about to + 動詞原形表示安排或計劃中的馬上就要發(fā)生的動作，后面一般不跟時間狀語I was about to leave when the bell rang.The meeting is about to close.5be to + 動詞原形表示按計劃進行或征求對方意見We’re to meet at the school gate at noon.6一般現(xiàn)在時表示將來時刻表上或日程安排上早就定好的事情，可用一般現(xiàn)在時表示將來The meeting starts at five o’clock.The plane leaves at ten this evening.II. 動詞的被動語態(tài)：常用被動語態(tài)構(gòu)成常用被動語態(tài)構(gòu)成1一般現(xiàn)在時am/is/are asked6過去進行時was/were being asked2一般過去時was/were asked7現(xiàn)在完成時have/has been asked3一般將來時shall/will be asked8過去完成時had been asked4過去將來時should/would be asked9將來完成時will/would have been asked5現(xiàn)在進行時am/is/are being asked10含有情態(tài)動詞的can/must/may be asked注意事項被動語態(tài)的否定式是在第一個助動詞或情態(tài)動詞后加not，短語動詞的被動態(tài)不可漏掉其中介副詞。如：I read the novel last month. (只說明上個月看了，不涉及現(xiàn)在是否記住)I lived in Beijing for ten years.（只說明在北京住過十年，與現(xiàn)在無關(guān)）3. 現(xiàn)在完成時與現(xiàn)在完成進行時的區(qū)別：兩者都可以表示“從過去開始一直持續(xù)到現(xiàn)在”，在含義上如著重表示動作的結(jié)果時，多用現(xiàn)在完成時，如著重表示動作一直在進行，即動作的延續(xù)性時，則多用現(xiàn)在完成進行時。五．介詞：1簡單介詞about, across, after, against, among, around, at, below, beyond, during, in, on2合成介詞inside, into, onto, out of, outside, throughout, upon, within, without3短語介詞according to, because of, instead of, up to, due to, owing to, thanks to4雙重介詞from among, from behind, from under, till after, in between 5分詞轉(zhuǎn)化成的介詞considering(就而論), including6形容詞轉(zhuǎn)化成的介詞like, unlike, near, next, oppositeII. 常用介詞區(qū)別：1表示時間的in, on, atat表示片刻的時間，in表示一段的時間，on總是與日子有關(guān)2表示時間的since, fromsince 指從過去到現(xiàn)在的一段時間，和完成時連用，from指從時間的某一點開始3表示時間的in, afterin指在一段時間之后，after表示某一具體時間點之后或用在過去時的一段時間中4表示地理位置的in, on, toin表示在某范圍內(nèi)，on指與什么毗鄰，to指在某環(huán)境范圍之外5表示“在…上”的on, inon只表示在某物的表面上，in表示占去某物一部分6表示“穿過”的through, acrossthrough表示從內(nèi)部通過，與in有關(guān)，across表示在表面上通過，與on有關(guān)7表示“關(guān)于”的about, onabout指涉及到，on指專門論述8between與among的區(qū)別between表示在兩者之間，among用于三者或三者以上
