　　[答案]　The “Foreign Cultures” section(外国文化栏目)，名词作主语。句意：我校校报中的“外国文化”栏目在我们学生中颇受欢迎。

　　2．[2015·江苏高考]It is everybody's duty to_observe_the_rules to keep our society in order and going on the right track.

　　[答案]　it作形式主语，动词不定式to observe the rules(遵守规则)作真正的主语。句意：为了使我们的社会井然有序，遵守规则是我们每个人的责任。

　　技能点拨　可以变化使用动词不定式、动名词或主语从句作主语，避免句子形式单一。如果主语只是一个名词，可以在名词前增加修饰、限定的形容词来为句子增添亮点，如fantastic scenery, effective method等。
