(A) and with its superiority to the horse being (B) and its superiority over the horse had been (C) and its superiority to the horse 答案是B 但是我有几个疑问 1. 答案B的格式是once A was done and B had been done,形式不是不对称了么?而且有什么理由B会发生在A之前? 2.白勇书的第13页关于省略句也有说明:‘两个句子并列,第一个句子含be动词或者become,第二个句子中的be动词或者become必须省略,同时,一些重复的名词或者形容词也必须省略’,而且他下面用的例子也正好就是本题,那个例子上写的是C选项的。 是书上的答案写错了还是怎么回事? 哪位NN能帮忙好心地解答下? 谢谢了! |
