语法题.The history course that I took last semester proved more

3个回答

  • the history course是主语 为名词

    that为关系代词

    i为子句中的主语 名词

    took后本该有一个名词作宾语,宾语即为the history course这里that代替了

    last semester是时间副词 到这里子句完整 结束

    proved 是另一个动词,实际上是整个句子的动词,即为the history course的动词

    more difficult是形容词,than在比较时总是和more在一起,作连词

    连词后为另一个子句,i had expected

    i 为该子句主语 名词

    had 为助动词

    expect 是该子句动词
