All flights （）because of the terrible weather,they had to go there by train.
A:having been cancelled B:had been cancelled
C:having cancelled D:were cancelled
答：A
譯：由于天氣惡劣所有航班取消了,所以他們不得不改乘火車去那兒.
析：本題考查獨立主格結(jié)構(gòu).
逗號后面的是主句,前面的是狀語,從句應(yīng)由連詞引導(dǎo),而句首沒有連詞,所以排除BD,因為這兩個是謂語動詞.
AC是現(xiàn)在分詞的完成式,航班是被取消的,排除主動式C.having cancelled
非謂語動詞作狀語,其邏輯主語一般就是主句中的主語.如果不是,則需要在前面帶上自己的,獨立于主句主語之外的邏輯輯上的主語,這就是獨立主格的“大部隊”.
PS：如果用B,則有兩種改法：
1.前面用從屬連詞As：As all flight had been cancelled.,they had to ...
2.中間用并列連詞so:All the flights had benn cancelled...,so they had to .
如果用D也可以,前面用從屬連詞after:
After all the flights were cancelled.,they had to .
