表语从句
位于系动词之后作表语的从句叫表语从句。 The problem is who is to pay and when we can start.

考点一 连接词 that / what 的选用
总结归纳:
that 和 what 都可引导所有的 名词性从句。但是,_w_h_a_t__除起连 接作用外,还在名词性从句中充当 成分,可作从句的_主_语__、_宾_语__、 _表___语___、或_定__语_。而_th_a_t__在名词性从 句中不充当任何成分,只起 __连__接___作用。
• 步骤二:如果从句中既不缺少主语,宾语, 表语,定语,但是缺少一定意义的状语, 则考虑用连接副词;
• 步骤三:如果既不缺少主语,宾语,表语, 定语,也不缺少状语,则考虑用从属连词。
