用最近热播的《三生三世十里桃花》为话题，给出四个翻译句子，并让学生说出每个句子属于名词性从句的那种类型。

1.____________________________________a recent hot topic is a truth. (become)

这部电视剧已经成为最近的热点是一个事实

2.Many people wondered ____________________________ .(attract)

很多人想知道为什么 “夜华” 吸引了那么多的粉丝。

理由可能是他拥有帅气的外表和强大的超能力。

4.Although this drama was interesting, the fact _____________________ is cast down.

尽管这部剧很有趣，但是我们不被允许看电视的事实令人们很沮丧。

（设计意图：用最近的热点作为话题导入新课，激发学生的学习兴趣。减小学生对于枯燥的语法学习的排斥感。另外这四个句子也是名词性从句的四种类型，最后一个是同位语从句，为下一步介绍同位语从句的结构作铺垫。）
