八年级英语下册2014年10月总第 18期 课 题: Unit 5 If you go the party, youll have a great time!主备： 王海燕 课型： 新授 班级：_学生：_ Section A （ second period ）【学习目标】1. 学习if引导的条件状语从句.2 . 重点词汇和短语: gym , stay at home, study for the test, make some food, ask somebody to leave, at the party, 【预习导学】1. If we have it today, half the class wont come. 如果我们今天聚会，班上一半的学生不会来。 (1) 句中的half为形容词，意为“半数的”，可以修饰名词，直接放在所修饰名词之前。half 也可以作名词，意为“一半；半”，常用结构为“half of + 名词”，当此结构作主语时，谓语动词要与名词的单复数形式保持一致。如： Half the students come from England. 半数的学生来自英国。Half of the boys go to the movies on Sundays. 一半的男孩在星期天去看电影。Half of the work has been done. 一半的工作已完成了。(2) class在句中为集合名词，指“全班的人”，强调组成班级的多个成员，谓语动词用复数形式，此类的单词还有family, school 等。如： The family are from China. 这一家人来自中国。2. If you wear jeans, we wont let you in. 如果你穿牛仔裤，我们将不会让你进来。 let为使役动词，其后接动词原形。let sb. in意为“允许某人进入”，in是副词，意为“在里面；向里面”，作宾语补足语。如：Lets play basketball. 我们打篮球吧。Please let him in. 请让他进去。3.解码同义句转换 (1). 用“祈使句 and 陈述句” 表示两分句之间是一种顺承关系，相当于if引导的条件状语从句：If you work hard, youll pass the exam easily. Work hard, and youll pass the exam easily. 努力学习，你将很容易通过考试。 (2) “祈使句+or+陈述句” or 表“否则”，“要不然的话” If you dont hurry up, youll miss the train. Hurry up, or youll miss the train. 快点儿，否则你就赶不上火车了。 (3). 用含介词with或without的介词短语转换。如： If there is no water, fish cant live. Fish cant live without water. 离开水，鱼不能生存。【随堂练习】一英汉互译。 1. 年终聚会 _ 2.班上的一半同学_ 3. 敬老院_ 4. let somebody in_5.take away _6.
