Unit 7 It’s raining! Section B 教材知识全解 讲透知识 查漏补缺 知识点一 have a great time doing sth.的搭配 教材原文 I'm having a great time visiting my aunt in Canada.我正在加拿大探望我姑姑,过得很开心. have a great time doing sth.意为“做某事很开心”,have a great time 意为“玩得开心;过得愉快”,与 have a good/wonderful time、have fun、enjoy oneself意思相同.如: They are having a great time playing in the water.他们在水里正玩得开心. 注意当得知某人要去某地旅游或玩耍时,要祝对方玩得开心,可以使用如下句式:Have a good time./Have a great time./Enjoy yourself./Have a good trip.等. 例(2020河南洛阳洛龙区第一实验学校五月月考)I think we have a good time________ English in Mrs. Liu's English class. A. learned B. learning C. learns D. learn 解析 have a good time 后若跟动词,只能用动名词. 答案 B 知识点二 on(a)vacation的用法 教材原文My family and I are on a vacation in the mountains.我和我的家人正在山里度假. on(a)vacation是固定搭配,意为“度假”,vacation前可以加不定冠词,也可以不加不定冠词.如: They are on vacation in Australia.他们正在澳大利亚度假. 注意vacation通常用在美式英语中,在英式英语中通常用holiday.如:summer holiday暑假. 例(2020四川成都七中育才学校六月阶段性检测)Look at the picture. Lisa is________ vacation in Canada________ her family. A. at; with B. on; with C. on; and 解析 本题考查介词的用法和搭配.句意:看这张照片.莉萨和她的家人正在加拿大度假.on vacation意为“度假”,先排除A项;with表示“和······一起”,故答案为B. 答案 B 知识点三 反意疑问句的结构 教材原文 It's hot in your country now, isn't it?你们国家现在很热,不是吗? 本句是反意疑问句,它由“陈述部分＋反意疑问部分”两部分构成.陈述部分如果是肯定形式,反意疑问部分就要用否定形式;陈述部分如果是否定形式,反意疑问部分就要用肯定形式.可巧记为“前肯后否”和“前否后肯”.如: He is a policeman, isn't he?他是警察,不是吗? It isn't cold today, is it?今天不冷,是吗? 拓展 如果陈述部分含有never、 hardly、nothing、nobody、few、little(表示“几乎没有”)等表示否定意义的词时,反意疑问部分要用肯定形式. She never plays computer games, does she?她从不玩电脑游戏,是吗? The boy wants to do nothing, does he?那个男孩什么事也不想做,是吗? 注意反意疑问句的答语要依据事实来回答,如果事实是肯定的,要用肯定答语;如果事实是否定的,要用否定答语.只是需要注意“前否后肯”结构的反意疑问句的答语的译文. 前肯后否 -She likes art, doesn't she?她喜欢美术,不是吗? -Yes, she does.是的,她喜欢.(事实是肯定的) 前否后肯 -The boy never watches TV, does he?那个男孩从来不看电视,是吗? -No, he doesn't.是的,他不看.(事实是否定的) 例Your mother hardly goes swimming with her friends, ________? A. does she B. doesn't she C. is she D. isn't she 解析 根据设空处前的goes可知,反意疑问部分要用does,先排除C和D项;再根据陈述部分的否定词hardly“几乎不”可知,反意疑问部分
