Unit 5知识点汇总
三、语法
1.do/does助动词
在一般现在时的否定句和疑问句中,帮助实意动词构成疑问句或否定句,其后的动词为动词原形。
如果主语是第三人称单数,用does.
陈述句:I have a volleyball. 一般疑问句:Do you have a volleyball? 否定句:I don’t have a volleyball.
He likes football. Does he like football? He doesn’t like football.
2.have v. 第三人称单数用has。
如:1) She has a very nice room. 2) She doesn’t have a very nice room.
3.let v. 让;允许
主要结构为:let sb. do sth. “让某人做某事”。
eg: Let me get it.否定形式:let sb not do….“让某人不要做某事”。
eg: Let’s not play basketball. let后的动词用原形。
Let us…=Let’s…
eg: Let’s go home. 我们回家吧。
Let’s play basketball. 我们打篮球吧。
4.well adv. 好;满意地;水平高
well和good都表示“好”。
但good是形容词,修饰名词;而well是副词,用来修饰动词、形容词和副词。
eg:She is a good painter. 他是一个好画家。
She sings very well. 她唱得非常好。
5.sound n. v. 听起来;似乎: 其后常接形容词eg:That sounds great! 这听起来好极了!
6.like v. 喜欢常用短语:like to do…/ like doing…eg:He likes playing football. 他喜欢踢足球。
7. interesting adj. 有趣味的;interested adj感到有趣的. 常用短语be interested in…表示“对……感兴趣”
eg:1) The film is very interesting. 2)I am interested in singing and dancing.。
