24、课堂变式】 How much is the ticket to Central Park?A one-way ticket _ $40, and you can_ another $20 for a round-trip.A. costs, pay B. cost, spend C. pay, spend D. spends, pay【解析】考查动词辨析。cost“花费”物作主语，spend“花费”人作主语，pay for付款， 人作主语，所以选择答案A。b.句式包：To cut down air pollution, we should takethebus or subway instea
25、d of driving.为了减少空气污染，我们应当乘坐公汽或地铁而不是开车。本句中To cut down air pollution是动词不定式作目的状语。动词不定式做目的状语时的用法一、不定式和不定式短语作目的状语不定式和不定式短语作目的状语，主要用来修饰动词，表示某一动作或状态的目的。为了使目的意义更加清楚或表示强调意义时，还可以在前面加 in order to 或 so as to。例如：Ive written it down in order not to forget.He shouted and waved so as to be noticed.在句子中作谓语动词的状语的不定式
26、或不定式短语，表示的是主语的目的，因此，其逻辑主语通常是句子的主语。比较：To draw maps properly, you need a special pen.(正)To draw maps properly, a special pen is needed.(误)由 in order to 引导的目的状语，既可以置于句尾，也可以置于句首，而由 so as to 引导的目的状语，只能置于句尾，而不能置于句首。比较：They started early in order to get therein time.(正)In order to get therein time, they st
27、arted early.(正)They started early so as to get therein time.(正)So as to get there in time, they started early.(误)二、不定式的复合结构作目的状语当不定式或不定式短语有自己的执行者时，要用不定式的复合结构(即在不定式或不定式短语之前加 for + 名词或宾格代词)作状语。例如：He opened the door for the children to come in.She fetched several bottles which she placed on the counter
28、 for Harry to inspect.三、目的状语从句与不定式的转换英语中的目的状语从句，还可以变为不定式或不定式短语作状语，从而使句子在结构上得以简化。可分为两种情况：1. 当目的状语从句中的主语与主句中的主语相同时，可以直接简化为不定式或不定式短语作状语。例如：Well start early in order that/so that we may arrive in time.Well start early in order to/so as to arrive in time.2. 当目的状语从句中的主语与主句中的主语不相同时，要用动词不定式的复合结构作状语。例如：I cam
29、e early in order that you might read my report before the meeting.I came early (in order) for you to read my report before the meeting.【课堂变式】1Why is Linlin practicing speaking English? _ abroad for further study.

30、o what I can _ you. A. help B. to help C. invite D. to invite【解析】考查动词的辨析和非谓语动词的用法。由交际情景可知此处表示“我将尽我能做的来帮助你。”help的意思是“帮助”，invite的意思是“邀请”，此处使用动词不定式表示目的。故选B。第二课时Section A（3a 3c）类别课时要点重点单词1. sharkn. 鲨鱼；2. finn. 鱼 鳍3. methodn. 方法；4. crueladj. 残酷的；5. harmfuladj. 有害的；6. chainn. 链条；7. ecosystemn. 生态系统；8. indus
