探究过程Processes of exploring:
【一般现在时】
一般现在时表示现在经常反复发生的动作、存在的状态或习惯性的动作的时态。构成一般现在时用行为动词的原形,但第三人称单数作主语时,动词的词尾要加-s。(一般的动词词尾+s。以sh/ch/s/x结尾的词+es.以辅音字母+y结尾的把y变成 i,+es。辅音字母+o结尾的+es.)
【用法】
1) 经常性或习惯性的动作,常与表示频度的时间状语连用。 时间状语always, usually, every morning /night/evening/day/week, ,often, sometimes, from time to time, twice a week ,seldom, never.
I leave home for school at 7 every morning.
2) 客观真理,客观存在,科学事实。
⑴The earth moves around the sun. ⑵Shanghai lies in the east of China.
3) 表示格言或警句中。Pride goes before a fall. 骄者必败。
注意★:此用法如果出现在宾语从句中,即使主句是过去时,从句谓语也要用一般现在时。Columbus proved that the earth is round..
4) 现在时刻的状态、能力、性格、个性。
I don't want so much.
Ann Wang writes good English but does not speak well.
比较:Now I put the sugar in the cup.
I am doing my homework now.
第一句用一般现在时,用于操作演示或指导说明的示范性动作,表示言行的瞬间动作。再如:Now watch me, I switch on the current and stand back. 第二句中的now是进行时的标志,表示正在进行的动作的客观状况,所以后句用一般现在时。
5).表示按规定、计划或时间表将要发生的事。
He starts next week. 他下个星期出发。
We leave very soon. 我们很快就离开。
The train starts at 10 o'clock in the morning. 火车将在早上10点开出。
这类用法限于表示“移动”的动词:go去,come来,leave离开,start出发,begin开始,arrive到达,take off起飞,等。
【特殊用法表将来】
1)下列动词:come, go, arrive, leave, start, begin, return, live, fly的一般现在时表将来。这主要用来表示在时间上已确定或安排好的事情。
The train leaves at six tomorrow morning.
When does the bus start? It starts in ten minutes.
2)倒装句,表示动作正在进行,如:Here comes the bus. = The bus is coming.
There goes the bell. = The bell is ringing.
3)在时间或条件句中。
When Bill comes (不是will come), ask him to wait for me.
I'll write to you as soon as I arrive there.
4)在动词hope, make sure that等后。⑴ I hope they have a nice time next week.
⑵ Make sure that the windows are closed before you leave the room.
