be句型。1．定語(yǔ)從句限定性定語(yǔ)從句中that可代表人和事，而which只代表事；二者在從句中作主語(yǔ)或賓語(yǔ)。that作賓語(yǔ)時(shí)?？墒÷?，which則不能，而且其后的“不及物動(dòng)詞+介詞’’中的介詞不能省略。which作賓語(yǔ)時(shí)，先行詞與which之間的介詞不能省。例如： first doll that could say“mama”was invented in 1830． second half of his voyage was by far the more dangerous part，during which he sailed round the Cape Horn．代表a11，anything，something，nothing，much等詞時(shí)，用that而不用which，that作賓語(yǔ)可省略。例如： care anything that has something to do with it．39。d better do something he prefers to do to please him． is the last time we met each other． came across the woman you told me about yesterday．who和whom引導(dǎo)的從句用來(lái)修飾人，分別作從句的主語(yǔ)和賓語(yǔ)。where是關(guān)系副詞，用于表示地點(diǎn)的定語(yǔ)從句，而when用來(lái)表示時(shí)間。whose是關(guān)系代詞，修飾名詞作定語(yǔ)。例如: Ford is the person who is most responsible for developing the idea of mass production． knee is the joint where the thigh bone meets the large bone of the lower leg． next morning，when she came down to breakfast，Mary was beaming with the pleasure of a new，great discovery． visiting professor is a famous scientist whose son studies in my department．在下列情況，限定性定語(yǔ)從句的關(guān)系代詞可以省略：1)當(dāng)關(guān)系代詞在從句中作賓語(yǔ)或表語(yǔ)；或它們?cè)趶木渲凶鹘樵~的賓語(yǔ)，而該介詞又在句末時(shí)；2)當(dāng)先行詞是that，all，only，everything，something，nothing等代詞時(shí)，或先行詞前有一個(gè)最高級(jí)形容詞修飾時(shí)；3)當(dāng)先行詞前有only，any，all，first，no，last等修飾時(shí)，或先行詞就是time，moment，way(anyway)，direction，distance等名詞時(shí)，關(guān)系代詞即可省略。例如： delegation we had been waiting for finally arrived． met the woman you told me about． gave me all she could afford． TV we can see things happen almost at the exact moment they are happening．非限定性定語(yǔ)從句，其作用為：對(duì)所修飾的成分作進(jìn)一步的說(shuō)明，它與主句用逗號(hào)隔開(kāi)。此類(lèi)從句省略后其余部分仍可成立。在非限定性定語(yǔ)從句中，which可代表前面的整個(gè)句子；代表人時(shí)只能用who，whom，而不能用that；as也可用作關(guān)系代詞。例如: telephone，as we know，was the invention of Alexander Graham Bell． Little White House in Warm Springs was the Georgia home President D．Roosevelt，who died there on April 12，1945． in a damp house for a long time is harmful to one’s health，which is known to

that等詞引導(dǎo))，地點(diǎn)狀語(yǔ)從句(由where引導(dǎo))，行為方式狀語(yǔ)從句(由as引導(dǎo))。有時(shí)條件狀語(yǔ)從句中，主句不可以用將來(lái)時(shí)，而用一般時(shí)代替。例如： small greenish flowers of the elm tree appear in the Spring，long before the leaves 39。s novels used to be so popular that her books appeared on bestseller balloon is less safe than hot balloon because it may catch acceleration(同樣的加速)occurs if the rate of change remains the same over successive equal intervals of time． of Chinese college students went to the US Consulate ，where they protested NATO39。s bombing at China39。s Embassy in “主語(yǔ)+be”可以省略，前提是：從句主語(yǔ)和主句主語(yǔ)一致，且從句謂語(yǔ)“be”省略后的結(jié)構(gòu)為“連詞+現(xiàn)在分詞／過(guò)去分詞介詞短語(yǔ)／形容詞／名詞短語(yǔ)”。)例如： well fitted，glasses can correct most sight defects in healthy eyes．

logarithm(對(duì)數(shù))is what is known in algebra exponent(代數(shù)的指數(shù))． thing I admire most about them is that they are hospitable． works too hard；That is why she is exhausted． must point out
