    we went through a period ___ communications were very difficult in the rural areas.
    A.which B.whose C.in which D.with which
    為什么選C 不選D
    也有 with the period 的說法啊
    with the period 也是指時(shí)期啊。為什么不能=when
    英語人氣:231 ℃時(shí)間:2019-12-10 05:46:20
    優(yōu)質(zhì)解答
    period 時(shí)期 后面就應(yīng)該用when 所以用in which相當(dāng)于when
    我來回答
