Period 2　Using language 表语从句 在复合句中充当表语的从句称为表语从句，一般位于系动词(be、look、remain、seem等)之后。这种从句往往是对主句的主语的进一步解释说明。 引导表语从句的词有： 从属连词 that、whether、as if/though、because 连接代词 what、who、whom、whose、which、whatever等 连接副词 when、where、how、why等 一、that和whether引导表语从句 (1)(译林必修一U2)The good news is that this stormy period will not last. 好消息是，这种风暴期不会持续太久。 (2)(译林选必一U1)What I love best about Sichuan hot pots is that they offer a great opportunity to socialize with friends since a meal can last for hours. 我最喜欢四川火锅的地方是它提供了一个很好的与朋友交往的机会，因为一顿饭可以持续几个小时。 (3)No children make no mistakes while they are growing up and the most important thing is whether they can learn from the mistakes. 没有一个孩子在成长过程中不犯任何错误，最重要的事情是他们能否从错误中吸取教训。 以上各句黑体部分均为表语从句，连接词that和whether在句中仅起连接作用，不作任何成分。　 that引导表语从句时仅起连接作用，无任何意义，在从句中不作任何成分，但通常不可省略。whether引导表语从句时起连接作用，意为“是否”，在从句中不作任何成分。注意：if不能引导表语从句。 单句语法填空 (1)(2023·全国乙卷)It seems that TV programmes have helped change what people think about cooking.
