题目

A few years ago the belief became general_orange juice and milk should never be drunk
接上at the same meal.
A.that B.so that C.and D.such as
这个题选A,为什么呢?怎么翻译.

答案

选a,主句是The belief became general.观念变得普遍
orange juice and milk should never be drunk at the same meal是用来补充主语The belief的
几年前,一个观念变的非常普遍,那就是橘子汁和牛奶不能在同一餐饭中饮用.
或者解释为几年前,橘子汁和牛奶不能在同一餐饮用的这么一个观念变的非常普遍.
so that是结果以至于,不符合上下文
and 虽然可以连接两个句子,但是不符合上下文,
such as 是举例子,因为前面the belief是单数的,所以没必要举例子.
