七下Unit 1&Unit 2知识点
一、语法
Hello,everyone!为了帮助同学们在期中诊断中取得更好的成绩,我们接下来会每周分享两个单元的知识点。今天我们和同学们一起探讨的是七下Unit 1和Unit 2的重要语法点和知识点,其中Unit 1主要学习情态动词can的用法和句型,Unit 2主要进行一般现在时的运用和时间的表达。根据老师接触的孩子,同学们容易忘记can后接动词原形以及动词忘加三单!!!所以同学们在做题的时候要注意这两点哦!
1、①情态动词can的用法:表示能力、可以,后接动词原形。
Eg. I can play football.
I can play the piano.
②句型转换:
肯定句:sb+can+do...
否定句:sb+can’t+do...
一般疑问句:Can +sb+do...? Yes,sb+can. No, sb can’t.
特殊疑问句:What can sb do? Who can do...?
3、What time /When 引导的特殊疑问句
①对做某事的具体时间点进行提问:What time /When 都可以
--What time /When do you go to school? --At seven o’clock.
②对做某事的非具体时间点进行提问:只能用When
--When is your school trip? -- It’s on Friday.
③对钟表显示的时间进行提问:只能用What time
--What time is it now? -- It’s 9:35
4、一般现在时---- 实义动词部分
一般现在时表示经常发生或习惯性的动作,常和always, usually, often, sometimes, every day, in the morning, on Sundays等时间状语连用。例如:
They go to school every day.
He smokes a lot every day.
Do you know his name?
If it doesn’t rain, we’ll go to the zoo.
关于行为动词在一般现在时中,当句子的主语是第三人称单数时,具体变化规律如下:
情况 |
构成规则 |
举例 |
一般的动词 |
在词尾加-s |
live→ lives eat→ eats |
以字母s, x, sh, ch和o结尾的动词 |
在词尾加-es |
go→ goes |
以“辅音字母+字母y”结尾的动词 |
改词尾的y为-ies |
carry → carries worry → worries |
特殊变化 |
没有统一的规则 |
have → has |
频率副词:做状语,位于实义动词前,be动词、情态动词、助动词之后。
always usually often
sometimes never
例:Lucy sometimes goes shopping after dinner.
Lucy is always happy.
Lucy can never play the piano.
Lucy doesn’t often do her homework in the evening.
二、词组
学习完语法之后,我们接下来一起进入到词组的世界!不知同学们有没有发现,我们七下的训练和诊断中对词组的运用越来越多,很多孩子也会反映完形填空中会遇到很多词组辨析,所以接下来每周老师会给同学们分享一些常考的短语和词组,同学们要坚持积累下去哦!
