Question

what she enjoys-----at the wekends A shopping B is shop C to shop D is shopping 为什么 选定D

Answer 1

What does she enjoy?（这样写你可以看出来enjoy的宾语其实是what）
She enjoys shopping at the weekends.
What she enjoys IS shopping at the weekend.
两句合并成一句后变成一个复合句，主系表结构，主语由从句what she enjoys充当了谓语动词是IS ，而shopping at the weekends 则是表语部分。在what she enjoys这个主语从句中，enjoy的宾语仍然是what而不是再在其后加上shopping，所以空格上却缺的是谓语部分is 及其后的表语shopping。

很多能接宾语的动词也常可改写成这种句子
She gave me a book.
What she gave me was a book.
She likes dancing.
What she likes is dancing.
