Ill pay it back next week. 你能借给我12块钱吗？下周还你。（6）pay off ones money还清钱。【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, payB. 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 take the bus or subway instead 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 there in time.(正) In order to get there in time, they started early.(正) They started early so as to get there in 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 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 came 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】1 Why is Linlin practicing speaking English? _ abroad for further study. A. Go B. Gone C. To go D. Goes 【解析】考查非谓语动词。动词不定式表目的。故选C。2. Im new here. Dont worry. Ill do what I can _ you. A. helpB. to helpC. inviteD. 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. shark n. 鲨鱼；2. fin n. 鱼 鳍3. method n. 方法；4. cruel adj. 残酷的；5. harmful adj. 有害的；6. chain n. 链条；7. ecosystem n. 生态系统；8. industry n. 工业；9. law n. 法律；重点词组1. shark fin soup鱼鳍汤2. at the top of the food chain处于食物链的顶端3. in the last 20 to 30 years在最近的20到30年间4. environmental protection groups around the world 全球环境保护组织5. develop laws 建全法律6. the sale of shark fins 鱼鳍买卖重点句式1.
