小升初英语一般过去时知识点

 一般过去时：主要描述过去发生的事情. 句末常出现last night/week/Monday/year, yesterday,ago

组成：主语+动词过去式

I was a pilot.

They were busy.

He went to the market.

否定句：在be后加not

在普通动词前加didn't，动词恢复原形。

I was not a pilot.

They were not busy.

He didn't go to the market.

疑问句：提前be 动词或在句前加did

-Were you a pilot?

-Yes, I was./ No, I wasn't.

-Were they busy?

-Yes, they were./ No, they weren't.

-Did they go to the market?

-Yes, they did. / No, they didn't.

动词变过去式：1. 在原次末尾加ed 或d如：play-played like-liked

2. 辅音加y 结尾去y加ied 如：study-studied

3. 辅音元音辅音结尾双写最后一个字母加ed 如：stop-stopped

特殊变化：can-could do-did eat-ate go-went

hit-hit pit-put sit-sat come-came

get-got have-had see-saw begin-began

give-gave win-won read-read

am/is-was are-were run-ran hear-heard

hide-hid lay-laid cut-cut wake-woke fall-fell

连系动词be是am, is, are三者的原形，一般不直接出现在句子中，而是以am, is,are的形式出现。它们各有分工，而且随着主语的人称和数的变化而变化。am最专一，始终跟着I转;are 跟you,

we及表复数名词或复数意义的词连用;is的交际最广泛，is与"他、她、它"形影不离，至于名词单数，指示代词(this/that)都与is结下不解之缘。
