【文章內(nèi)容簡介】 s you remember the day on which you joined our club? 還記得你加入我們俱樂部的那一天嗎？Do you remember the day when you joined our club? as, which 非限定性定語從句由as, which 引導(dǎo)的非限定性定語從句，as和which可代整個主句，相當(dāng)于and this或and that。As一般放在句首，which在句中。例如：As we know, smoking is harmful to one39。s ，吸煙有害健康。The sun heats the earth, which is very important to ，這對我們?nèi)祟惡苤匾?。典型例題1）Alice received an invitation from her boss, ___came as a ，不能用 that修飾，而用which.，it 和he 都使后句成為句子，兩個獨立的句子不能單以逗號連接。況且選he句意不通。2）The weather turned out to be very good, ___ was more than we could 答案B。which可代替句子，用于非限定性定語從句，而what不可。That 不能用于非限定性定語從句，it不為連詞，使由逗號連接的兩個句子并在一起在英語語法上行不通。3）It rained hard yesterday, ____ prevented me from going to the park.. 和which在引導(dǎo)非限制性定語從句時，這兩個關(guān)系代詞都指主句所表達(dá)的整個意思，且在定語從句中都可以作主語和賓語。但不同之處主要有兩點：（1）as 引導(dǎo)的定語從句可置于句首，而which不可。（2）as 代表前面的整個主句并在從句中作主語時，從句中的謂語必須是系動詞；若為行為動詞，則從句中的關(guān)系代詞只能用which.。在本題中，prevent由于是行為動詞，所以正確選項應(yīng)為B。as 的用法 same…as；such…as 中的as 是一種固定結(jié)構(gòu), 和……一樣……。例如：I have got into the same trouble as he（has）.我碰到了跟他一樣的麻煩。，常帶有39。正如39。例如：As we know, smoking is harmful to one39。s ，吸煙有害健康。As is known, smoking is harmful to one39。s 。例1中的as作know的賓語；例2中，它充當(dāng)從句的主語，謂語動詞know要用被動式。 先行詞和關(guān)系詞二合一1）Whoever spits in public will be punished here.（Whoever 可以用 anyone who 代替）2）The parents will use what they have to send their son to technical school.（what 可以用all that代替） what/whatever。that/what。who/whoever1）what = the thing which；whatever = anything。例如：What you want has been sent 。Whatever you want makes no difference to ，跟我沒什么關(guān)系。2）who= the person that whoever= anyone who。例如：（錯）Who breaks the law will be punished.（錯）Whoever robbed the bank is not clear.（對）Whoever breaks the law will be ，與庶民同罪。（對）Who robbed the bank is not 。3）that 和 what當(dāng)that引導(dǎo)定語從句時，通常用作關(guān)系代詞，而引導(dǎo)名詞性從句時，是個不充當(dāng)任何成分的連接詞。賓語從句和表語從句中的that?？墒÷浴hat只能引導(dǎo)名詞性從句，用作連接代詞，作從句的具體成分，且不能省略。例如：I think（that）you will like the 。What we need is more 。 關(guān)系代詞that 的用法 1）不用that的情況a）引導(dǎo)非限定性定語從句時。例如：（錯）The tree, that is four hundred years old, is very famous ）介詞后不能用。例如：We depend on the land from which we get our 。We depend on the land that/which we get our food ）只能用that作為定語從句的關(guān)系代詞的情況a）在there be 句型中，只用that，不用which。b）在不定代詞，如：anything, nothing, the one, all, much, few, any, little等作先行詞時，只用that，不用which。c）先行詞有the only, the very修飾時，只用that。d）先行詞為序數(shù)詞、數(shù)詞、形容詞最高級時，只用that。.e）先行詞既有人，又有物時。例如：All that is needed is a supply of 。Finally, the thief handed everything that he had stolen to the 。定語從句練習(xí): is the train ____ we went to which that you ever been to Rome?No, but that39。s the I most like to visit 39。d most like to visit I like to visit most I39。d like most to visit keeps a record of everythinghe had seen said that Suzhou was the first cityhe had visited in TV play I watched last night is the best one I have watched this this the museum you visited the other day? which one is the very filmI39。ve long wished to is no difficultycan39。t be overe in the is the personis standing at the gate of Beijing Tourism Tower? a teacher, I seldom give my students so difficult a problem ______they can not work order that house the capitalist used to live in is now a nursery（托兒所）. is the last timeI shall e here to help neighbors used to give me a hand in time of trouble, was very kind of now know why Mao impresses everyone who meets him whit the way _________he C.／ is the baby whom I shall look I shall look after I shall look after whom I shall look after was no longer the womanshe 39。s the hotel last we stayed that we stayed we stayed at we stayed doctor did all to save the wounded he could he could which he could which he could do this opinion may speak againsts against is against are against placeyou are standing used to be an old 39。ve made the same mistake you made last is not such an interesting magazineI D.／ know, he is a
