小學英語語法-時態篇
小學英語語法 一般過去時態
（a） be 動詞的過去式:
I/He/she/it was(not)…. You/we/they were….
一般疑問句was, were 放在句首。
（b） 動詞過去式：
肯定句： I watched cartoons.
She visited the zoo.
一般疑問句： Did you read book last night? Yes, I did. No, I didn't.
Did she clean the desk just now? Yes, she did. No, she didn't.
否定句： They didn't go the the part yesterday.
He didn't make model ships last week.
小學英語語法 一般現在時
通常用 "usually, often, every day, sometimes"。
肯定句：
I go to school on foot every day.
She goes to school on foot every day.
一般疑問句:
Do you jump high? Yes, I do. / No, I don't.
Does he jump high? Yes, he does. / No, he doesn't.
否定句： We don't go to school on Sundays.
My mother doesn't like watching TV in the evening.
小學英語語法 一般將來時
一般將來時主要用于：
表示將要發生的動作或情況
e.g. Tom will have a bike of his own.
與這個時態連用的時間狀語常用：
tonight, tomorrow, the day after tomorrow, next week, in three hours, two days later 等。
一般將來時態與其它結構表將來情況的區別：
一般將來時態 ：主要從時間的角度表將要發生的動作或情況。
be going to 結構 ：①表（主觀上）打算或準備做某事時。 ②表有發生某事的預兆時。
e.g. They are going to have a competition with us in studies. It is going to rain.
據以上區別，故下面一句是錯的：
I am going to be eighteen years old next year.
應改為： I shall be eighteen years old next year.
be about to do sth 結構 ：意為"剛要做某事"、"馬上要做某事"強調時間之緊迫性。
e.g. We are about to discuss this problem.
小學英語語法 一般過去時現在完成時
一般過去時現在完成時主要用于：
1 、表示到現在為止這一時期中發生的動作或情況，即多次動作的總和。
e.g. We have learnt four English songs this month.
How many times have you read the novel?
For many days we haven`t seen each other.
2 、表示對現在有影響的某一已發生的動作。
e.g. The delegation has left 代表團已經走了（說明現在不在這里）
Look, what you have done. 看你干的事。
與這一時態連用的時間狀語有：
already, yet, just, ever, never, by now, so far, recently, by the end of this month, since, for 短語，連詞 since 引導的時間狀語從句。
一般過去時與現在完成時的區別：
一般過去時：重在說明動作在過去發生時的具體情況（時間、地點、方式、對象、細節等）。
現在完成時：只提起已發生的動作（事實）及其影響，不說明動作發生時的具體情況。
cf. Have you had your lunch?
What did you have for lunch?
I have ever been to the Great Wall,_and_I went there last summer with my father.
注：現在完成時表達的動作常具有反復性，故下面一句是錯的：
Have you seen the six thirty`s news program?
應改為：
Did you see the six thirty`s news program?
小學英語語法 一般過去時
一般過去時主要用于：
1 、表示過去某個時間發生的動作或情況（包括習慣性的動作或狀態）
e.g. When did you read the novel?
She often came to help us in those days.
2 、談到過去的情況時
e.g. I didn`t know you were so busy.
3 、談到已死人的情況時
e.g. Lei Feng was a great communist fighter.
與這個時態連用的時間狀語常有：
yesterday, last night, the other day, two months ago, in 1985, then, just now,
when, after, as soon as 引導的時間狀語從句，表示主句動作開始的時間。
