Unit 7 The Sea词汇篇2____________________________________________________________________________________________________________________________________________________________________1、掌握第7单元第二三课的重点单词，短语及句型。2、灵活运用第7单元第二三课的重点单词，短语及句型。一、课时重点话题谈论海洋污染的现状、缘由及危害,增强保护环境的意识词汇核心词汇energy,melt,protect,disappear话题扩展词汇suppose,handle短语及搭配remind sb. to do sth,break the law,deal with重要句型1.There are too many fishermen fishing in the same place.2.Often it is quite difficult to find who’s responsible for pollution.3.They also try to help people to get other kinds of jobs so there are less people trying to make a living from fishing.功能Interaction 相互交流二、单词词组重点1. How can we deal with this problem? 我们如何才能处理这些问题呢？deal with 意为“处理，处置；对付，应付”。如：How are you going to deal with the water pollution of this area? It is very difficult to deal with noisy children. 辨析: do with 也是“处理，处置；对付”之义。区别在于：deal 为不及物动词，本身不需要宾语；do为及物动词，本身需要宾语。如： You must do all you can with the examination. 你必须尽最大努力准备好这次考试。What shall we do with the problem? /How shall we deal with the problem? 我们将如何处理这个问题？.?2.If you miss some information, write a question mark to remind you to listen especially carefully the second time. 如果你错过了一些信息，写一个问号来提醒你第二次特别仔细地去听。remind sb. to do sth. 提醒某人做某事。如：I reminded him to come back before dark. 拓展: remind sb. of sth. 使某人回想起某事。如：The lovely Mickey Mouse doesnt remind people of the unfavour-able images of mice and rats. 可爱的米老鼠并没有让人们想起老鼠那不好的形象。3.Its three times as big as underwater. 水下部分是水上部分的三倍。该句为as…as句型，as big as underwater 后面省略了as that above water. 该句three times 为状语，修饰as…as句型。比较句型中的状语要放在第一个as或比较级之前。如：This box is twice as big as that one. The ship can run three times faster than small boat. 误区警示：不要受汉语干扰而把“大三倍”说成bigger three times. 4. There?are?fantastic?shows?every?two?hours.?“every+基数词+复数名词”，表示“每……，每隔……”。?如：?I?go?there?every?three?days.?我每隔两天就去那里一趟。?He?stopped?and?turned?round?every?few?meters.?每隔几米他就停下来回头看看。?拓展:?我们还可以用“every+序数词+单数名词”来表达同样的意思。?Every?four?years=every?fourth?year?每四年，每隔三年?every?two?da
