CNN Student News is a ten﹣minute,commercial﹣free,daily news program ______ middle and high school classes,______ is available Monday through Friday during the school year.( )
A.adapted for; it B.meant for; that
C.intended for; this D.designed for; which
D
句中design作program的后置定语,要用非谓语动词;design与被修饰名词program构成动宾关系,要用表示被动的过去分词;is available Monday through Friday during the school year是修饰program的一个非限制性定语从句;从句缺少主语,要用which来引导.故选D.
点评 过去分词是非谓语动词的一种,用法很灵活,分为简单式done(表示与谓语同时或几乎同时发生的动作);完成式having been done(表示先于谓语的动作).学习时,要把握其用法特征:表示被动和完成.同时还要注意区分现在分词和不定式.
