九年级英语上册Unit 4 Amazing Science Topic 2 When was it invented Section A学案（无答案）学习目标：课前预习: 一1a导学：朗读一遍对话，了解大致意思。然后补充空白：Kangkang asks Jane why she is_(不高兴), Jane tells Kang she _ _ _ _(不被允许去)play computer games because it_ _ _(对有害) her health if she_ too much time_ (花费在上)them.

Kangkang wishes he could go into the space _ _ (某一天)and Jane hopes his dream will_ _(实现). 1a语言点导学：1. Because Im not allowed to play computer games. 因为不允许我玩电脑游戏。allow v. 意为“允许，准许”。 常用句型结构有： 准许某人做某事 _ 允许做某事_Eg: 我们的老师允许我们放学后踢足球。 _ 我们不允许在教室里吃东西。 _2. I wish I could go into space some day. 这是个含虚拟语气的句子，表达了康康的主观臆想，不一定能实现，所以情态动词用了can的过去式could。辨析：hope, wish相同点：两者均表示“希望，想”；hope/wish to do sth. Eg: 我希望能去参观颐和园。_不同点：Eg: 我希望你去。_我希望我是一只小鸟。_我希望你很快好起来。_二.1b导学:观察以下词组，找出不同后填写:1.这个用英语怎么说? _ _ _ _? _ _ _ _ _?2. be made of _be made from _be made up of _ 3. be used for _be used to do _be used as _used to do sth. _be used to doing sth. _拓展：be made in + 地名/国家名 表：_ be made into + 产品名 表：_be made by + sb. 表：_三：2a导学：n When was it developed?
