题目内容
7.The Internet gives students the chance to have the materials they need ______to them quickly and cheaply.( )A. | to deliver | B. | deliver | C. | delivering | D. | delivered |
分析 网络让学生有机会可以让他们需要的材料快速便宜地送达.
解答 答案:D
题干中they need是修饰materials的定语从句;deliver sth to sb送某物给某人;materials与deliver之间构成动宾关系,要用被动;have sth done让某物被怎样.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.
