32、处,1、两种从句都可以译成定语 e.g.,The news that our team has won the final match is encouraging. 我们队取得决赛胜利的消息令人鼓舞。The news that you told us is really encouraging.你告诉我们的消息真的令人鼓舞。,（同位语从句）,（定语从句）,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

33、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.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,（定语从句）,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

34、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.Dad made a promise that he would buy me a CD player if I passed the English test. 2) Dad

35、 made a promise that excited all his children. （that指代promise，又在从句中充当主语。）,（that 不充当任何成分）,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 practi
