Question

英语!
The results are quite different from______.
答案是what we expected.为什么不能选 those of which we expected?
还有：
______ was the center of our planetary system was a difficult concept to grasp in the Middle Age.
答案是That was the sun and not the earth.
为什么Being the sun and not the earth.不可以呢?而且我每次对being 这个用法都特别难懂.

Answer 1

what we expected在句子中可以做成分,是一个整体,those of which we expected就不可以
同样的道理That was the sun and not the earth也是作了句子成分,是主语,如果是Being the sun and not the earth的话句子中有两个谓语动词了Being和was,不符合语法,记住:有Being的话句中不能再有别的谓语动词,如be 动词等,如果想用的话加and,并不是所有的都可以用and连接的
