新概念英语第二册重点语法Lesson93

　　重要句型或语法

　　1、被动语态

　　本课主要对比复习第21课、第45课和第69课出现的被动语态的用法，主要包括不同时态中的被动语态、与情态动词的连用、不定式结构的被动语态、被动语态所在的从句改为短语结构等。如：

　　A letter was delivered this morning.

　　Your bag must have been stolen in the shopping mall.

　　I was asked to finish the work before Friday.

　　After having been instructed to drive out of town, he began to acquire confidence.

　　2、重音

　　本课难点部分出现的是有关重音的内容，主要讲的是同一个词语，经常会因为词性不同，而发音不一样，主要的体现就是重音位置不一样。如：present作为名词的发音为['preznt]，但作为动词的发音为[prɪ'zent]。

　　4)注意美国的全称为the United Stats of America，所以其简称为USA。
