        have的用法;
        have +過(guò)去分詞,構(gòu)成完成時(shí)態(tài)。例如:
        He has left for London. 他已去了倫敦。
        By the end of last month, they had finished half of their work.  上月未為止,他們已經(jīng)完成工作的一半。

          have + been +現(xiàn)在分詞,構(gòu)成完成進(jìn)行時(shí)。例如:

          I have been studying English for ten years. 我一直在學(xué)英語(yǔ),已達(dá)十年之久。

          have +been +過(guò)去分詞,構(gòu)成完成式被動(dòng)語(yǔ)態(tài)。例如:
