  • 一般现在时的用法:

    1) 经常性或习惯性的动作,常与表示频腮度的时间状语连用.

    时间状语: every…, sometimes, at…, on Sunday

    I leave home for school at 7 every morning.

    2) 客观真理,客观存在,科学事实.

    The earth moves around the sun.

    Shanghai 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.

    例: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.

    一般现在时表将来:

    1)下列动词:come, go, arrive, leave, start, begin, return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 star? It stars 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, take care that, make sure that等后.

    I hope they have a nice time next week.

    Make sure that the windows are closed before you leave the room.

    一般过去时和完成是

    1、过去时表示过去某时发生的动作或单纯叙述过去的事情,强调动作;现在完成时为过去发生的,强调过去的事情对现在的影响,强调的是影响.

    2、过去时常与具体的时间状语连用,而现在完成时通常与模糊的时间状语连用,或无时间状语.

    一般过去时的时间状语:

    yesterday, last week,…ago, in1980, in October, just now, 具体的时间状语

    共同的时间状语:

    this morning, tonight,this April, now, once,before, already, recently,lately

    现在完成时的时间状语

    for, since, so far, ever, never, just, yet, till / until, up to now, in past years, always,

    不确定的时间状语

    3、现在完成时可表示持续到现在的动作或状态,动词一般是延续性的,如live, teach, learn, work, study, know.

    过去时常用的非持续性动词有come, go, leave, start, die, finish, become, get married等
