英语时态

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 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 -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. -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
