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
