名词性从句的从属连词在从句中只起连接作用，不作成分，主要包括that, whether/if。 ①To start with, what I intend to stress is that we are about to start our next lesson in Classroom 8 of the Teaching Building at 10 a．m. next Friday.(2017·全国卷Ⅰ书面表达)

名词性从句的连接代词在从句中起连接作用，并在从句中充当主语、表语、宾语、定语，主要包括what, which, who, whom, whose, whatever, whoever, whomever, whichever等。

二、名词性从句的写法
在写作中，如果能够把两个简单句合并为一个含有名词性从句的复合句，或者把一个简单句扩展成为含有名词性从句的复合句，对写作都是一种质的升华。
名词性从句在写作时可采用“三步法”：
[示例]
第一步：写出两个简单句。 ①He said a lot at the meeting. ②His words were very attractive.
第二步：让句①作主语从句，可转换为“他在会上所说的话”，即What he said at the meeting。
第三步：把句①转换的主语从句和句②连在一起。
What he said at the meeting was very attractive. [即时演练]
用名词性从句将下列每组简单句合并为一个复合句
1．When did you enter the room？The police wants to know it. →The_police_wants_to_know_when_you_entered_the_room.
2．Finally I want to express my hope. All the younger fellows can make full use of time.
→Finally_I_want_to_express_my_hope_that_all_the_younger_fellows_can_make_full_use_of_time.
3．The book can be of help to anyone. He wants to do the job. →The_book_can_be_of_help_to_whoever_wants_to_do_the_job. 4．Shall we go picnicking tomorrow? It depends on the weather. →Whether_we_shall_go_picnicking_tomorrow_depends_on_the_weather. 5．The meeting has been put off till next Monday.
