首先 我把各种时态的基本用法梳理出来，然后在常考的时态后面有归纳的考点。
一、一般现在时
表示现在习惯或者经常反复发生的动作或存在的状态，常与always, often, usually, seldom, sometimes, frequently, every day/week/year…, on Sunday(s),…等时间状语连用。谓语直接用动词，但如果主语是第三人称单数的时候要进行变化。
变化规则如下：
1.一般直接在后面加s helps cleans walks
2.以辅音字母加y结尾的改y 为 i+es studies hurries carries
3.以o, s, sh, ch,结尾的加 es does finishes watches
肯定句：主语+动词(s)+(宾语)+…
We play football every afternoon.
我们每天下午踢足球。
Jack watches TV on Saturday evening.
杰克星期六晚上看电视。
否定句：主语+don’t/doesn’t+动词原形+( 宾语) + …
Tom doesn’t clean his room in the morning.
汤姆早晨不打扫房间。
They don’t go to the library on Monday.
他们星期一不去阅览室。
一般疑问句：Do/Does+主语+动词原形+…?
肯定回答:Yes,主语+do/does. 否定回答：No,主语+don’t/doesn’t.
—Does she live in Wuhan? —Yes, she does/No, she doesn’t.
—她住在武汉吗？—是的，她住在武汉/不，她没有住在武汉。
—Do you read English every morning ? —Yes, I do/No, I don’t.
—你每天早晨读英语吗？—是的，我读英语/不，我不读英语。
特殊疑问句：疑问词+do/does+主语+动词原形+…?

频度副词always/often/usually 等,位置在行为动词之前、be动词和助动词之后。
1. He often comes late.
He is often late.
他常迟到。
2. We usually go back in the evening.
We are usually back in the evening.
