连词：that, whether, if (在从句中均不充当任何成分)。
连接代词：what, whatever, who, whoever, whom, whomever, which, whichever等。
连接副词：when, where, how, why, whenever, wherever, however等。
注意：that在名词性从句中不作任何成分，但在主语从句、表语从句、同位语从句中也不能省略，在引导宾语从句时，第一个宾语从句中的that可以省略；that引导的宾语从句作介词的宾语时，that不可以省略；whether和if意为“是否”，在宾语从句中可以互换使用(注意介词后面的宾语从句只能用whether引导)；在表语从句、同位语从句、主语从句且主语从句位于句首时，只能用whether。从句均用陈述语序。
一、主语从句
1．主语从句：在复合句中充当主语成分的从句。

②It is＋形容词 (true, certain, clear ...) that ...
③It is＋过去分词 (said, reported, believed ...) that ...

2．it作形式宾语，常用的动词有：find, make, feel, think, consider等。
I find it necessary that_we_do_some_reading_every_day.

I would appreciate it if_you_could_stay_for_lunch.
4．在suggest, demand, insist, order 等动词后的宾语从句中， 谓语动词要用虚拟语气，即 (should＋)动词原形。

注意：whether和if引导宾语从句时大多数情况下可以通用，但其他情况下二者还是有一定的区别。下列情况下一般用whether不用if：
①引导主语从句且从句位于句首、表语从句、同位语从句时；
②作介词或discuss的宾语时；
③与or not连用时；
④用在不定式前面时。

________________________________________________________________________
答案：whenever→whatever 句意：锻炼使得你更加清醒从而为这一天中要面临的困难做好准备。handle后面的宾语从句中缺少主语，而whenever作时间状语，故将whenever改为whatever。
14．(2018·全国卷Ⅲ)That is only evidence which traditions once existed.
________________________________________________________________________

名词性从句(二)
三、表语从句
1．表语从句：在复合句中充当表语成分的从句。通常位于be动词或系动词look, seem等之后。
The problem is when_we_can_get_a_pay_rise.
That is what_I_want_to_tell_you.
2．表语从句可以用as if/though 引导，意为“好像……”。
It looks as_if it is going to rain.
3．because引导的表语从句强调原因，而why引导的表语从句强调结果。
That's because_he_doesn't_understand_me.
He was busy. That's why_he_didn't_attend_the_meeting.
4．“The reason why ... ＋be＋that从句”结构。
The_reason_why he was absent was_that_he_was_ill.
四、同位语从句
1．同位语从句：在主从复合句中，用作同位语的从句，叫同位语从句。它一般跟在某些抽象名词之后，如：fact, idea, news, promise, doubt, truth, hope, suggestion, belief等后面，用以解释说明这些名词。
I have no idea when_Chaplin's_film_will_be_on_again.
We were very excited at the news that_our_team_had_won.
The fact that_women_can_work_as_well_as_men is clear.
Henry Adams made a promise that_he_would_not_open_the_letter_until_2_o'clock.
2．同位语从句与名词之间有时会被句子的其他成分隔开，形成间隔性同位语从句。
Word came that_our_team_had_won_the_game.
3．that引导的同位语从句与定语从句的区别：
同位语从句只是说明或解释前面名词的具体内容，that在从句中只起连接作用，不充当句子成分；定语从句用来修饰限定前面的名词或代词，关系词that在从句中既起到连接作用，又在从句中充当成分。
Have you heard the news that_our_team_won_the_game? (同位语从句)
Have you heard the news that_was_reported_from_the_front？(定语从句)
