☆时态☆
小学阶段一共学了四种时态,分别是:一般现在时,一般将来时,现在进行时,一般过去时。下面我们一一进行总结。
1、 一般现在时
A、表示不受时限的客观存在
如:He is a boy. She is a student. My mother is a nurse.
This is a dog. I have a story-book.
B、表示现在的习惯动作,即指现在经常发生的动作,一般现在时常用来表示现在时间里某种动作的经常性和习惯性。它常与表示程度或频度的词连用,如:often(经常) , usually(通常,一般) , sometimes(有时) , always(总是,一直) , never(从不)
如:I often go to school on foot. My father works in a school.
Mike watches TV every day.
I usually play computer games on the weekend.
C、表示现时的状态和现在瞬间动作
如:How are you? You look happy.
What’s the matter with you? I have a headache.
What do you have for lunch? I have some chicken.
☆注意☆ 英语动词的现在时与原形同形。但当主语是第三人称单数时,须在词尾加-s 或 -es。例如:
I have a fish for dinner. Her mother works in a hospital.
Amy often goes to school by bike. Mr. Liu teaches us English.
加-es 的动词必须是以“sh , ch , o ”等字母结尾的。
如:watches , teaches , goes , washes
2、 一般将来时
表示在将来会发生的事或动作。它常与表示将来的时间连用,如:tomorrow , next week , next year , this morning , this afternoon , this evening 等。
☆注意☆ 一般将来时小学阶段主要学了两种结构:
①be going to + 动词的原形 / 地点 ②will + 动词的原形
例句: I’m going to go shopping this afternoon.
She is going to Hong Kong next week.
You will see many birds in the sky.
3、 现在进行时
表示说话时正在进行的动作或现阶段一直在进行的动作。
☆注意☆它的构成是:be的现在时形式(am , is , are)加动词的ing形式。如:What are you doing? I’m writing a letter.
What are they doing? They’re swimming.
Is he playing chess? Yes, he is.
Look, Amy is reading an English book.
☆注意☆ 动词的ing形式的构成规则:
① 一般的直接在后面加上ing ,
如doing , going , working , singing , eating
② 以e 结尾的动词,要先去e再加ing ,如having , writing
③ 双写最后一个字母的(此类动词极少)有:running , swimming , sitting , getting
4、一般过去时
主要用来表示在特定过去时间中一次完成的动作或一度存在的状态,也可表示过去的习惯动作。它与现在时间不发生关系,它表示的动作或状态都已成为过去,现已不复存在。它经常与表示过去的时间连用。如:
I went to a park yesterday. I read a book last night.
I watched TV yesterday evening.
I went on a big trip last weekend. I failed my Chinese test.
☆注意☆ 一般过去时主要体现在动词的形式要用过去式,动词的过去式的构成规则有:
A、规则动词
① 一般直接在动词的后面加ed ;
如 worked , learned , cleaned , visited
② 以e结尾的动词直接加d ;如 lived , danced , used
③ 以辅音字母加y结尾的动词要改y为i再加ed (此类动词较少)如 study – studied carry – carried worry – worried
(play、stay除外)
④ 双写最后一个字母(此类动词较少)如 stopped
B、不规则动词(此类词并无规则,须熟记)小学阶段要记住以下动词的原形和过去式:
sing – sang , eat – ate , see – saw , have – had , do – did , go – went , take – took , buy – bought , get – got , read – read , fly – flew , am/is – was , are – were , say – said , leave – left , swim – swam , tell – told , draw – drew , come – came , lose – lost , find – found , drink – drank , hurt – hurt , feel – felt
