  • present perfect tense

    亲:有点多,只能缩减了.

    现在完成时的结构:have/has +v-ed(过去分词)

    概念:属于现在的时态,动作发生在过去,但于现在情况有关系.

    以动词work为例:

    肯定式

    I/We/You/They have worked.

    He/She worked.

    否定式

    I haven't worked.

    He hasn't worked.

    疑问式

    Have you worked?

    Has he worked?

    带有下列时间状语

    already,never,ever,always,not...yet,now,today,this month,since+具体的时间,for+一段时间

    例如:I have worked here for a year.我在这里工作了一年.

    I have worked here since 2009.自从2009年以来我就在这里工作了.

    亲:每天都开心V_V!

    thanks!
