动词的时态语态
一 一般现在时
(一)定义:主要用来表示人、事物的现在状况和特点;表示经常或习惯性的动作,句子中常有often, always, from time to time 等时间状语; 表示客观规律和永恒真理等
He usually goes to work at 7 o’clock every morning. The earth goes around the sun.
Guangzhou is situated in the south of China.
(二)标志词:
always, usually, often, sometimes, hardly ever,every week (day, year, month…),
once /twice a week, on Sundays,
(三)谓语动词构成:
1 be动词的一般现在时 :am is are("是", “在”)
2 当谓语动词是行为动词的时候:
(1)当主语不是第三人称单数的时候,一般现在时用行为动词的原形
(2)主语是he,she,it等第三人称单数(除去I,you以外的任何一个单数的名词或者代词),动词要变形加s或es.
(温馨提示:动词变形要符合两个条件:1,主语是三单,2,句子是肯定句)
(四).基本结构:
1,肯定句:主语+谓语(+其他的)
He loves sports. Jane is an outgoing girl.
(主语He是三单,又是肯定句,所以谓语动词发生变形,加上了s)
Tom and Tim both have medium height.
He has a big mouth. We like the dog very much.
2,否定句: 主语+don’t或者doesn’t+动词原形+其他 (在be或者后面加上do does)
Candy doesn’t do her housework every day. We don’t dance .
He isn’t a worker.
3,一般疑问句: Do (Does)+主语+动词原形+其他?(把be或者do does 提到主语的前面)
Does sh
