英語定語從句考點(diǎn)及命題規(guī)律分析

1. 考查which引導(dǎo)的非限制性定語從句

which引導(dǎo)非限制性定語從句，用以指代整個(gè)主句的內(nèi)容，或主句中某個(gè)詞或短語的內(nèi)容。如：

(1) By serving others, a person focuses on someone other than himself or herself, _______ can be very eye-opening and rewarding.

A. who                  B. which                C. what                  D. that

答案為B。which在此引導(dǎo)非限制性定語從句，which在定語從句中用作主語，表示前面所提到的情況。

(2) Chan’s restaurant on Baker Street, _______ used to be poorly run, is now a successful business.

A. that                   B. which                C. who                   D. where

答案為B。which used to be poorly run為非限制性定語從句，其中的which指代前面的China’s restaurant。

2. 考查as引導(dǎo)的非限制性定語從句

as也可指代整個(gè)主句的內(nèi)容，但不同于which的是，它引導(dǎo)的定語從句既可以位于主句的前面，也可以位于主句的后面。它的意思是“正如”，在這些從句中as 作主語或賓語。如：

(1) _______ I explained on the phone, your request will be considered at the next meeting.

A. When               B. After                  C. As                         D. Since

答案為。as 引導(dǎo)定語從句，其意為“正如”。

(2) _______ is often the case, we have worked out the production plan.

A. Which              B. When                C. What                 D. As

答案為D。解析：引導(dǎo)非限制性定語從句且位于主句之前，用as引導(dǎo)。答案分別為CBD。

3. 考查由“介詞＋關(guān)系代詞”引導(dǎo)的定語從句

“介詞+關(guān)系代詞”結(jié)構(gòu)中的關(guān)系代詞主要是which或whom，不能是that；其中的介詞則要根據(jù)句子中的相關(guān)搭配來確定。如：

(1) He was educated at the local high school, _______ he went on to Beijing University.

A. after which      B. after that           C. in which           D. in that

答案為A。after which中的which指“他在當(dāng)?shù)匾凰�高中接受教�?/FONT>”，after which的意思就是“在當(dāng)?shù)匾凰�高中接受完教育之�?/FONT>(即高中畢業(yè)之后)”。
