Whether与 if均可使用的情况 ⑴引导宾语从句 ⑵在be+adj.之后 He was not sure whether/if it is right or not. 2、what 与that的区别 ⑴that引导名词性从句，不在从句中充当任何成分，只起连接作用；what是连接代词，在从句中充当成分作主语、宾语或表语。除表明具体的内容外，还表……的时间、地点、人、速度等。 ① made the school proud was more than 90%of the students had been admitted to key universities.

After seemed a long time, he managed to work out this problem. ⑵介词后的宾语从句常用what引导，不用that引导。但在介词besides,except,in后可用that引导宾语从句。由it做形式宾语时，that引导的宾语从句中，that不可省略。 ①Criticism and self- Criticism is necessary in that it helps us to correct our mistakes. ②He noticed that the straight part of the dance was different in the afternoon from it had been in the morning. ③The suit fitted him well the color was a little brighter.

See to it that children don’t catch cold. ⑵that在主语从句、表语从句和同位语从句中不可省略。在宾语从句和it做形式主语的主语从句中可省略；但当有两个或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。 She said (that) she had left school and that her parents would find her a job. ⑶固定用法：like it; dislike it; have it; appreciate it 一般与if 或 when 引导的从句连用。 I like it in the autumn when the weather is clear and bright. 四、that引导同位语从句与定语从句的区别 that引导同位语从句时，that是连词，应在某些抽象名词之后，如：fact,hope,desire,thought等，对前面的名词起补充说明作用，它在从句中不充当任何成分，不能省略，；that引导定语从句时，that是关系代词，在从句中充当主、宾和表语。 The news that they had won the game arrived soon . 从句 The news that you told me yesterday is true. 从句 高中英语名词性从句精讲精练 （09安徽）1._______ a certain doubt among the people as to the practical value of the project.
