狀語(yǔ)從句有很多,其中時(shí)間狀語(yǔ)從句、條件狀語(yǔ)從句是最主要的。它的時(shí)態(tài)由主從句相呼應(yīng)來(lái)決定,條件狀語(yǔ)從句表達(dá)將來(lái)的情況,但主句為一般將來(lái)時(shí),從句為一般現(xiàn)在時(shí)態(tài);時(shí)間狀語(yǔ)從句則“主將從現(xiàn),主過(guò)從過(guò)”,過(guò)包括一般過(guò)去時(shí)和過(guò)去進(jìn)行時(shí)兩種情況。結(jié)果狀語(yǔ)從句也很重要,其次是原因、目的、讓步、方式和比較狀語(yǔ)從句,這些從句的時(shí)態(tài)主從句一致即可。這些從句已經(jīng)在“連詞”中復(fù)習(xí)到了。
