理工类职称英语考试语法学习笔记(3)

　　第四句型：主语 + 及物动词 + 双宾语

　　有些动词后面需要或可以接双宾语结构，如：give, write, buy, send, make等

　　You may send him an E-mail or write him a letter.

　　这个句子也可使用以下结构：

　　You may send an E-mail or write a letter to him. 所以 to 和 for 是连接双宾语结构的重要介词。

　　该句型的重点是要记住以下短语，特别是所用的介词：

　　to cure of

　　to accuse of

　　to convince of

　　to inform of

　　to notify of

　　to clean of

　　to warn of / against

　　to cheat of

　　to rob of

　　例如：

　　We have to inform the family of the patients condition as soon as possible. / Have the family been informed of the patients condition?

　　注意下面句子的结构变化：

　　May I ask you a question? May I ask a question of you?

　　直接和间接宾语的位置与上面短语有何不同?
