七年级英语Unit2复习教案
一、同步知识梳理
知识点1:let型祈使句 (P18)
(1)Let's celebrate!这是由let引导的祈使句,祈使句是英语的基本句型之一,这个句式常用来表示说话人的建议、请求、命令等。它的句型是“let+人称代词宾格+动词原形”,即“let+sb+do+sth”。
eg: Let's go and see our English teacher.
Let me help you find it.
注:let's和let us略有不同,“let's+动词原形”结构表示祈使对象包括说话人和听话人双方在内,而“let us+动词原形”结构表示请求对方允许自己(第一人称复数)做某事时,这里的us 不包含听话人在内,不能缩写。
(2)let型祈使句的否定形式分两种:
含第三人称主语的祈使句的否定形式在句首加don't。
含第一人称主语的祈使句的否定式不再句首加don't,而是用“let +sb+not+do”
eg: Don't let him in.
Let's not laugh at her.
知识点2: Eddie, do you like any sports? 艾迪,你喜欢运动吗? (P18)
(1) like vt. 反义词是 dislike 不喜欢
like sth./sb. 喜欢某物/某人(表泛指用复数) I like dogs.(泛指) He doesn’t his teacher.
like doing sth. 喜欢做某事(表示人的兴趣、爱好及经常性的活动) I like playing the violin, but today I like to play football. 我喜欢拉小提琴(经常的,爱好),但是今天我想踢足球。(偶然性)

sport 不可数名词,表示体育运动的总称 He likes sport not music. 他喜欢运动,不喜欢音乐。
可数名词,表示“(某项)运动” Football is an exciting sport.足球是一项令人兴奋的运动。
知识点3:Yes, I like walking. 是的,我喜欢散步。 (P18)
walking 名词,“散步,行走”(动词+ing 变成名词,也叫动名词),动词形式为 walk, 意为“走,步行”
eg:Walking in the morning is good for people.
walk 动词,“走,步行,”可与on foot 进行同义句转换 He walks to school every day.= He goes to school on foot every day.
可数名词,“走,步行”,尤指为娱乐或运动所做的“散步”,常构成短语 take/have a walk 散步 go for a walk 去散步 go out for a walk 出去散步

time作不可数名词时意为“时间”
eg:It’s time for me to go to bed.

知识点7: I enjoy swimming. 我喜爱游泳 (P19)
enjoy vt. 享受…的乐趣;喜爱,喜欢,欣赏 后加名词或动名词
eg :He enjoyed the food very much. / They enjoyed her singing./ He enjoys swimming.
enjoyment n. 享受,乐趣,享有
enjoy,like和love的用法区别
相同点:enjoy,like和love都有“喜爱”的意思,后面都接动名词,在口语中三个可以通用。
区别:love 用作动词时,比like表达的语气和感情都强烈;like仅表示喜欢,没有多少感彩,而love则是热爱,含有强烈的感彩;enjoy本身有使人感到快乐的意思,有喜爱到是一种享受的含义;like与love既可用于like/love doing sth,也可用于like/love to do sth,但enjoy后只跟动名词,即enjoy doing sth。

hope 与 wish的用法

二、同步语法精讲
行为动词一般现在时的用法
1. 行为动词三单形式变换规则:
(1) 大部分动词直接加‘s’。如like ---likes play----plays
(2) 以一个辅音字母加y结尾的,去掉y加ies。如study----studiesfly---flies
(3) 以sh, ch, ss,x 结尾的加es。如wash----washes watch-----watches dress----dresses fix----fixes
(4) 以o 结尾的加 es 。如 do----does go----goes
2. 主语为第三人称单数的行为动词的各种句型注意点。
肯定句 如: Millie gets up at 6:30 every morning.
否定句 如: Millie does not / doesn’t get up at 6:30 every morning
一般疑问句 如: Does Millie get up at 6:30 every morning? 肯定回答: Yes, she does. 否定回答:No, she doesn’t.
对划线部分提问: What does Millie do every morning?
【课堂小结】
主要是进行了一般现在时的用法讲解,内容看似简单,但是一般现在时的含义和用法考查的很多。判断使用一般现在时的步骤:首先,观察句中有无明显的标志语,如always, sometimes, twice a week等。其次,在没有标志语的情况下,要对句子意思进行仔细的翻译,看是否要表达习惯性动作、状态或客观规律。做一般现在时题目时一定要区分主语,注意应用动词原形还是第三人称单数。
