七年级下册英语知识点人教版2021
一. 情态动词can的用法
can+动词原形，它不随主语的人称和数而变化。
1. 含有can的肯定句：主语+can+谓语动词的原形+其他。
2. 含有can的否定句：主语+can't+动词的原形+其他。
3. 变一般疑问句时，把can提前：Can+主语+动词原形+其他? 肯定回答：Yes，主语+can。否定回答：No，主语+can't.
4. 含有can的特殊疑问句：特殊疑问词+can+主语+动词原形+其他?
I can speak English.→I can't speak English.→Can you speak English? →What can you speak?
二. what time和when引导的特殊疑问句
1. 询问钟点时用what time，询问日期、月份、年份时用when。
2. What's the time?=What time is it?现在几点了?

顺读法：“钟点+分钟”直接读数字。

逆读法：借助介词past或to表示，要先说分再说钟点。
a. 当分钟不超过30分钟时(包括30分钟)，即<或=30，用past表示。其结构为：“分钟+past+整点” 意为“几点过几分”。
如：1:25 twenty-five past one
b. 当超过30分钟时，即>30，用to表示。其结构为：“所差分钟(即60—所 过分钟数)+to+下一个整点”，to译成“差”，差几分钟到几点。
如：4:38 twenty-two to five
c. 当分钟为30分钟用half表示，当分钟为15分钟用a quarter。

七年级英语重要知识点
Do you have a soccer ball?
句型: Do you have a TV? Yes, I do/No, I don’t.
Do they have a computer? Yes, they do./No, they don’t.
Does he have a tennis racket? Yes, he does./No, he doesn’t.
Does she have a soccer ball? Yes, she does./No, she doesn’t.
Does he have a ping-pang ball? Yes, he does./No, he doesn’t.

语法：1,句中不含be(am,is,are)动词的 一般疑问句的变法。 也就是说句中谓语动词是实义动词时，要变为一般疑问句，在句首加do/does(当主语是第三人称单数的时候用does),第一人称变第二人称，动词变原形其他的语序不变。I have a computer. – Do you have a computer? She likes playing ping-pang.- Does she like playing ping-pang.肯定回答用yes, 主语+do/does.否定回答用No,主语+don’t/doesn’t.
2一般句子中当主语是第三人称单数的时候，谓语动词要起变化。具体的变化为：一般情况加s, know-knows,以s,x,ch,sh,o结尾的加es, teach-teaches, go-goes, 以辅音字母加y结尾，把y改为i, 再加es study-studies
3, do/does 叫做助动词(语法需要加上去翻译部出来的动词)时，后面接动词原形，
Does he like reading? She doesn’t like reading. She doesn’t do her homework.
但是如果做实义动词(能翻译出来意思的动词)呢，遇到主语第三人称单数就要起变化。
She does her homework.
4，have的第三人称单数为 has.
5, let sb do sth 让某人做某事 (sb代表人，如果是代词用宾格，do代表动词原形)
6，play+球类 表示“踢，打，玩......” play football
play+the+乐器 表示“弹奏……乐器” play the piano
unit6 Do you like bananas?
