◆概念提示
重点/热点1：Having realized that I could use a kite to attract Iightning , I decided to do an experiment.
该句中的having realized是v-ing形式的完成式在句中作状语。having done表示非谓语动词的动作先于渭语动词的动作，并且非谓语与句子主语之间存在着主动关系；having been done表示非谓语动词的动作先于渭语动词的动作，并且非谓语与句子主语之间存在着被动关系。其否定形式是在v-ing前加not。
Having finished his homework, the boy decided to play football for a while. 做完了作业．他决定去踢一会儿球。
Not having cleaned the classroom, they couldn't go home. 还没有打扫完教室，他们还不能回家。
Having been praised in class, the girl felt very happy. 那个姑娘在班上得到表扬，感到很高兴。
易混易错点1： be to do sth作表语的句型结构：be to do结构除了可以表示将来时的基本用法外还可以用来表示安排、命令、职责、用途、决心、命中注定要发生的动作等。be to 在某种程度上等于should , ought to 或must
(1) 表示命令
You are to be back by11 o'clock. 你得在11点钟前回来。 (2) 表示职责
I am to inform you that the meeting will be held in Hang Zhou .我谨通知你会议在杭州举行。
(3)表示命令
A knife is to cut with. 刀是用来切割的。(用途) (4)表示命令
