一般现在时
表示现在经常反复的动作和客观事实，一般规律。
一．构成
(一) 动词为Be动词：
1. 肯定句：be分为am, is, are,根据主语来变。
1) I am a teacher.
2) He is my teacher.
3) They are my teachers.
4) The mountains are very high.
2. 否定句：在be动词后加not
1) I am not a teacher.
2) He is not a teacher.
3) They are not teachers.
4) The mountains are not very high.
3. 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 a teacher?
—Yes，I am.
(—No，I'm not.)
4. 特殊疑问句：
特殊疑问词+ be+主语+动词+其他？
1) Who are you?
2) What is this?
(二). 动词为实义动词：
当主语为非单数第三人称是句中的谓语动词为实义动词原形；当主语为单数第三人称单数的时候，谓语动词用单数第三人称形式：
1. 肯定句：
I get up in the morning.
He gets up in the morning.
He and Tom run quickly.
2. 否定句:
否定句中，要在实义动词前面加助动词do/does+not，do/does本身无意义，常与not缩写成don't(doesn't)，如：
I don't like vegetables.
He doesn’t like vegetables.
3. 一般疑问句：
要在句子开头加助动词Do/does，句中动词用原形，句尾用问号。
简略答语用Yes，主语+do(does).或No，主语+do(does)+not.如：
(1). Do you like oranges?
Yes，I do.
No，I don't.
(2). Does he like oranges?
Yes, he does.
No, he doesn’t
4. 特殊疑问句：特殊疑问词+ do/does +主语+动词+其他？
(1) What does he do?
(2) When do you get up?
二、用法
(一) 一般现在时表示经常性或习惯性的动作，常与表示频度的时间状语every day, usually, always, often, sometimes, on Sunday等连用。如：
I go to school at 6 every morning. 每天早上我七点去上学。
(二) 一般现在时表示客观存在及普遍真理。如：
Summer follows spring. 春天之后是夏天。
The sun rises in the east. 太阳从东方升起。
注意：此种用法即使出现在过去的语境中，仍用一般现在时。如：
I learned that the earth goes around the sun when I was in primary school. 我在小学就学过地球是围绕太阳转的。
(三) 一般现在时表示格言或警句。如：
Pride goes before a fall. 骄者必败。
(四) 一般现在时表示目前的情况或状态。如：
I am a teacher. 我是教师。
Peter writes good Chinese but does not speak well. 彼得汉语写得不错，讲的可不行。
(五) 以here, there等开始的倒装句，表示动作正在进行。如：
Here comes the bus. = The bus is coming. 车来了。
There goes the bell. = The bell is ringing. 铃响了。
在下列情况下表示将来：
1. 在状语从句中用一般现在时代替一般将来时。如：
I will give it to him as soon as I see him. 我一看见他就交给他。
He will come if you invite him. 如果你请他,他会来的。
Suppose he doesn’t agree，what shall we do?假如他不同意，那怎么办?
I shall do as I please. 我高兴怎么做就怎么做。
He will continue the work no matter what happens. 不管发生什么情况他都要继续这项工作。
2. 在the more…the more …(越……越……) 句型中,前者通常用一般现在时代替一般将来时，因为前者相当于条件状语从句。如：
The harder you study, the better results you will get. 你学习越努力，成绩就会越好。
3. 在make sure (certain) , see to it, mind, care, matter后的宾语从句的谓语动词用一般现在时代替一般将来时。如：
See to it that you are not late again. 注意别再迟到了。
4. 表示按计划或时间表将要发生的动作，通常有表示将来的时间状语。如：
The plane takes off at 11:30 and arrives in Shanghai at l:20. 飞机十一点半起飞，一点二十分抵达上海。
注：只限于少数动词能这样用，如 begin, start, , end, finish, stop, go, come, leave, sail, arrive, return, close, open 等。
