1、Unit 2 English around the world教学目标：词汇：dare , unless , respect短语：admit doing , as a result , with Mrs Chen teaching me 语法：现在完成进行时have/has been teaching重难点突破：1.Shes very strictwe dont dare to say a word unless she asks us to.她很严格如果她不要求，我们连一句话也不敢说。dare“敢，有勇气”；dare用法要点归纳：作实意动词时，用法同一般实意动词 作情态动词时，用法同其它情态

2、动词 1）dare用作实义动词，可用在肯定句、否定句和疑问句中。有人称和数以及时 态的变化，变化时借助于助动词do。后面接带to的不定式，在否定句中不定 式符号to可省略。例如： I dare to jump down from the top of the wall. 我敢从那墙头上跳下来。 She doesnt dare (to) meet her teachers eyes. 她不敢与老师对视。 2）dare用作情态动词，后跟动词原形，主要用于疑问句、否定句和条件句。后面接不带to的不定式；没有人称和数的变化，但有一般过去式dared。疑问句用：Dare he / they /you？否

3、定句用：darent。例如： How dare she do things like that to me? 她怎么敢对我做那种事? Dare you catch the mouse? 你敢去抓那只老鼠吗？ I darent do that. 我不敢抓。 If you dare say that to our teacher, I would vote for you. 如果你敢向我们的老师说那件事，我就投你一票。练习：The little girl go downstairs alone when her parents are out.A. dares not to B. dares no

4、tC. dare not to D. dare not共0条评论.unlessununless的用法：unless是从属连词，引导条件状语从句，含有否定意义，相当于if条件状语从句的否定形式。所以unless=ifnot。译为“除非,如果不”注意：unless引导的条件状语从句和if条件状语从句，与其它时间状语从句一样，用一般现在时代替将来时。例如：Unlessyoutakemorecare,youllhaveanaccident. 如果不多加小心的话，你会出事故。Unlessbadweatherstopsme,Ijogeveryday.除非坏天气作梗，每天我都慢跑。练习: _ you cal

5、l me to say youre not coming, Ill see you at the theatre. (04 全国) A. Though B. Whether C.Until D.Unless2.Ill do well in the exam with Mrs Chen teaching me.由陈老师教我，我一定会考好的。with Mrs Chen teaching me为“with+复合宾语（宾语+宾补）”结构，在句中作状语。with复合结构的类型：with+宾语+doing/done/adj./adv./介词短语/to do。指点迷津：现在分词作宾补表示主谓及动作正在发生；

6、过去分词作宾补表示被动及动作已完成；不定式作宾补表示一个还未发生的动作。练习：(1) 用动词的适当形式填空：With winter _(come) on , its time to wear warm clothes.The murderer was brought in , with his hands _ (tie) behind his back.
