一般现在时
1.概念:一般现在时表示经常的、习惯性的动作或存在的状态。
2. 一般现在时的构成
一般现在时的构成主要有两种形式:
(1)be型:句子的谓语动词只有be(am,is或are):
a.肯定句中,只出现be,如:I am a student.我是一名学生。
b.否定句中,要在be后面加not,如:She isn't a teacher.她不是教师。
c.一般疑问句,要将be放在句子开头(注意句首字母大写),句尾用问号,答语用Yes,主语+be.或No,主语+be+not.如:
—Are you ready?—你准备好了吗? —Yes,I am.—是的,我准备好了。
(—No,I'm not.—不,我没准备好。)
(2)实义动词型:句中的谓语动词为实义动词(也叫行为动词):
a.肯定句中,只出现实义动词,如:I get up in the morning.我早晨起床。
b.否定句中,要在实义动词前面加do(does)+not,do(does)作助动词,本身无意义,常与not缩写成don't(doesn't),如:I don't like vegetables.我不喜欢蔬菜。
c.一般疑问句,要在句子开头加助动词Do(does),句尾用问号,简略答语用Yes,主语+do(does).或No,主语+do(does)+not.如:
—Do you like oranges?—你喜欢桔子吗?
—Yes,I do.—是的,我喜欢。
(—No,I don't.—不,我不喜欢。)

1) 经常性或习惯性的动作,常与表示频度的时间状语连用,如:every…, sometimes,
at…, on Sunday等。

2) 客观真理,客观存在,科学事实。
The earth moves around the sun. 地球绕着太阳。
Shanghai lies in the east of China. 上海位于中国的东部。
3) 表示格言或警句中。
Pride goes before a fall. 骄者必败。
4) 现在时刻的状态、能力、性格、个性。
Xiao Wang writes good English but does not speak well.
小王的英语书面表达能力比口语好。
