高中英语语法：名词性从句,定语从句

【考点点拨】
名词性从句可分为主语从句、宾语从句、表语从句和同位语从句。
近几年高考对名词性从句的考查重点如下：
【考点1】名词性从句中引导词that与what的使用场合。
1． that 引导名词 性从句时，不在从句中充当任何成分，只起连接作用；而what是连接代
词，在从句中充当成分。
① ______ made the school proud was _______ more than 90% of the students had been admitted
to key universities.
A. What because B. What that C. That what D. That because
2．that在主语从句、表语从句和同位语从句中不可省略, 但当有两个和两个以上的宾语从句
并列时，第二个从句以下的that不可省略。
如：She said (that) she had left school and that her parents would find her a job.
② Word comes ________ a group of Australian guests will come to visit our school next week.
A. that B. which C. 不填 D. about which
3．介词后的宾语从 句常用what，whether引导，不用that，which引导。但在介词besides，
e xcept，in后可用that引导宾语从句。在有it作先行词时，that可用来引导介词后的宾语从句。
③ The other day, my brother drove his car down the street at ____ I thought was a dangerous
speed.
A. as B. which C. what D. that
【考点2】名词性从句中引导词whether与if 的用法区别。

引导及物动词或形容词后的宾语从句
可以互换的场合： He is not sure if whether he can manage to do it.
当与or not分开使用时
He wondered if whether we will attend the meeting or not.

引导表语从句、同位语从句及位于句首的主语从句
只能用whether不能用if的场合： 引导介词后的宾语从句（有时可省略）
后面紧跟or not时
后面直接跟动词不定式时

A. If what B. Whether that C. When that D. Whether what
【考点3】在 动词：一坚持（insist）、二命令（order，command）、三建议（suggest，advi se，
propose）、四要求（demand，require，request，ask）后的宾 语从句和这些动词的过去分词后

do形式。
⑤ I advised that he _____ to the hospital at once, but he insisted that he _____ quite well then.
A. be sent; was feeling B. was sent; sent

时态保持一致 。

【考点5】whoever，whichever， whatever，whenever，wherever和however在引导名词性从
句时不可与 no matter who which what when where how 替换，因为后者只能引导让步主
语从句。

—— Thanks. I’ll telephone you from _____ I get to by tomorrow evening.
A. wherever B. every place C. whenever D. no matter where
定语从句可分为限制性定语从句与非限制性定语从句。
高考对定语从句的考查常涉及以下几个方面：
【考点6】正确区别限制性定语从句与非限制性 定语从句的结构；理解关系代词和关系副词
在定语从句中的作用；特别注意指代整个主句内容的关系代词 which引导的非限制性定语从
句。

指人时常只用who不用that的情况；
指物时只用which不用that的情况；
只用that不用which的情况；
关系代词as与which的用法区别；
the same … that … 与the same … as …的区别
⑨ There is no such place ______ you dream of in all this world.
A. that B. what C. which D. as
【考点8】区别that引导的定语从句与that引导的同位语从句。 that引导同位语从句时，that
是纯连词，在从句中不充当任何成分；that引导定语从句时， that是关系代词，在从句中充
当主语或宾语等。
比较：
