小學(xué)生英語(yǔ)語(yǔ)法知識(shí)點(diǎn)：現(xiàn)在進(jìn)行時(shí)

現(xiàn)在進(jìn)行時(shí)
    表示正在發(fā)生的事情或進(jìn)行的動(dòng)作，常與now，listen，look等詞連用，結(jié)構(gòu)是主語(yǔ)+be動(dòng)詞(am， is， are)+動(dòng)詞ing.
    如：It is raining now.
    外面正在下雨
    It is six o’clock now.
    現(xiàn)在6點(diǎn)了
    My parents are reading newspapers in the sitting room.
