All flights __ because of the terrible weather,they had to go there by train.A having been canceledB had beed cancledC having canceledD were canceled正确答案是A 2和4为啥不行
选A啊.B是完整结构,但后半句也是完整结构,而两个完整句子必须由并列连词或从属连词连接,所以B不对;C缺少be动词,不是被动结构;D同B
后半段是主句,前半段只能是独立结构,B和D都构成了句子,所以不行。
A
D独立主格结构,前后主语一致,
这个只能选A 非谓语动词题
因为没有连词故排除B和D
A
这是属于非谓语的考察。从题目当中我们可以看到句子已经有谓语动词had to go了,也就是说前面不可以填动词,因为一个句子只能有一个谓语动词,除非并列句子或主从句。而上面的句子既不是主从句也没有并列连词,所以判断前面必须填非谓语。所以B/D选项是错误的。根据非谓语having done 或者having been done表示在主句动词动作发生之前,而且,all flights 是被they ca...

这是一个句子,前面的表示原因,应该是原因状语从句来修饰后面的。故只能用ing,如选B及D,就成了两个句子,是汉语的习惯说法。
如果选B和D的话 缺 从属连词because 或者 逗号后 缺 并列连词so
所以答案是 A having been canceled
独立主格结构 作原因状语
All flights having been canceled because of the terrible weather,they had to go there by train.

逗号前后没有连接词,说明只有一个句子,也就是一个谓语,had to go是谓语,BD选项是谓语,所以不可以选。 航班被取消,用被动,所以选A.
这个句子里面没有连接词,所以只能有一个谓语。
1. 如果选B, 需要在句首加一个连词after,或者在后半句加一个连词so.
2. 如果选D,在后半句前面加连词and.
英语和中文不同,凡是两句话之间必须使用连词。
