3．宾语从句的时态
一般情况下，宾语从句须与主句的时态保持一致，即当主句是一般现在时时，从句可根据具体情况选用合适的时态；当主句为过去的某种时态时，从句须用相应的过去的某种时态。

当从句的内容为真理或客观事实时，须用一般现在时。

名词性从句与语法填空
1．首先确定空格处所在从句是否为名词性从句。

然后分析从句在整个句中所充当的成分，确定从句所属类型：主语从句、宾语从句、表语从句还是同位语从句。

2．判断从句中的连接词。

(1)若从句不缺少成分则要考虑句意是否完整，若句意不完整，则需用whether/if；若
句意完整，则用that。

(2)若从句缺少主、宾或表语，则用连接代词。

(3)若从句缺少状语，则用连接副词。

另外，还需注意一些特殊的引导词(如whether，because，as if 等)的用法。
