7、answers Step2. Grammar ★ 關系代詞與關系副詞辨析 定語從句的考查主要集中在引導詞的確定上。準確判斷引導詞在定語從句中所作的成分是選擇引導詞的關鍵。關系代詞that, which, who, whom在從句中作主語和賓語，作賓語時可省略；關系副詞where, when, why在從句中作狀語；whose在定語從句中作定語，起限定作用。 下面，請大家用適當?shù)囊龑г~填空，完成下列句子。 1.

10、 7. which 8. where ★“介詞+關系代詞”引導定語從句 關系代詞在定語從句中作介詞賓語時，從句常由“介詞+關系代詞”引導。介詞后的關系代詞主要是which和whom，間或是whose，但不能是that。有時，介詞前可有數(shù)詞、代詞、形容詞比較級或最高級修飾。 下面，請大家根據(jù)漢語提示，用定語從句完成下列句子。 1. In the dark street, there wasn’t a single person _____ (她可以求助). 2. The boss, _____ (我媽媽在他的公司工作), is a warm-hearted young man.

12、lp 2.in whose pany my mother works 3.at the back of which was a wheat field 4.80% of which are sold abroad 5.two of whom are college teachers 6.the largest of which is Asia ★ 限制性和非限制性定語從句 限制性定語從句是先行詞不可缺少的修飾部分，去掉它主句意思往往不明確；非限制性定語從句用來對主句內(nèi)容作補充、解釋或附加說明，和主句的關系不十分密切，沒有它，主句意思仍然完整。非限制性定語從句和主

13、句之間往往用逗號分開。注意：關系代詞that不能引導非限制性定語從句；在非限制性定語從句中即使關系代詞which, whom在從句中作賓語，也不能省略。 下面，請大家把下列句子譯成漢語，并分析、比較其意義的不同。 1. My brother who is an engineer is 25 years old. 2. My brother, who is an engineer, is 25 years old. 3. Mr. Smith, who used to be my English teacher, will retire next month. 4. The teach

14、er who used to teach me English will retire next month. ★ 定語從句中的主謂一致 關系代詞作主語時，定語從句中謂語動詞要與先行詞在人稱和數(shù)上保持一致。注意：當先行詞是one of ...時，定語從句中謂語動詞用復數(shù)；當先行詞是the one of ...或the only one of ...時，從句中謂語動詞用單數(shù)。下面，請大家用括號內(nèi)所給詞的適當形式填空。 1. Those who _____ (want) to go to the film tonight please sign here. 2. He who ______

16、hich都可以指代整個主句或主句的一部分，引導非限制性定語從句，并且在定語從句中作主語或賓語。其中，as引導的非限制性定語從句位置較靈活，可以位于主句前、中或后，而which引導的定語從句只能放在主句后。 下面，請大家根據(jù)括號內(nèi)的漢語提示，用定語從句完成下列句子。 1. The result of the experiment was very good, _____ (這大大出乎我們的意料). 2. _____ (眾所周知), China has the largest population in the world. 3. The boy was late for class ag

17、ain, _____ (這使得老師非常生氣). 4. He can write a letter in English, _____ (我不行). ★定語從句中關于that的使用 1.當先行詞為anything，everything，nothing等不定代詞時，只能使用“that”。 Is there anything I can do for you? 2.當先行詞為all，any，much，many詞時，只能使用“that”。 Tom told her mother all had happened. 3.當先行詞是形容詞最高級或被形容詞最高級修飾時，
