2、两种从句都可以用that引导 e.g. The suggestion that students should learn something practical is worth considering. （同位语从句） 学生应该学些实用的东西的建议值得考虑。 The suggestion that is worth considering is that the students should learn something practical. （定语从句）值得考虑的建议是学生应该学些实用的东西。 一、同位语从句与定语 从句的相似之处 二、同位语从句与定语 从句的不同之处 1、从句的作用不同：同位语从句用来进一步 说明前面名词的内容；定语从句用来修饰、 限定前面的名词。 e.g. The news that our team has won the final match is encouraging. （从句说明“消息”的内容：我们队取得了决赛胜利。） The news that you told us is really encouraging. （从句对“消息”加以限定：是你告诉我们的，而非来自其他渠道。但消息是何内容却不得而知。） 二、同位语从句与定语 从句的不同之处 2、引导从句的关联词that的功能不同：that引导同位语从句时是一个纯连词，不充当任何成分；而引导定语从句的that是关系代词，既指代先行词又须在从句中充当成分。 e.g.1) Dad made a promise that he would buy me CD player if I passed the English test. （that 不充当任何成分） 2) Dad made a promise that excited all his children. （that指代promise，又在从句中充当主语。） Tell the difference 1.The news that the plane would take off on time made everybody happy. 2.The news that is spreading around the airport is that a heavy storm is coming. 3.The suggestion that students should learn something practical is worth considering. 4.The suggestion that they are considering is that students should learn something practical.

Tell the function of the clauses in the following sentences说出下列从句的功能：A: Appositive（同位语）; B: Attributive（定语） His proposal that we go there on foot is acceptable.

B B B 如果由两个或多个连接词引导一个主语从句时，谓语动词用单数。 主语从句的位置 主语从句可以放在句首，也可以放在 句末。 放在句末时用it做形式主语。 把主语从句放在句末，常用下面几种句型： 常用it 做形式主语的句型有： 1) It+ be +名词+ that 从句 2) It+ be + 形容词+ that从句 3) It+ be + 动词的过去分词+ that从句 4) It+ 不及物动词+ that从句 5) It + vt. + sb. + that
