Which do you enjoy ______ your spare time, playing cards at home or taking a walk in the park?

我知道可以填 to spend 构成目的状语。但我的另一个理解是 enjoy spending your spare time (in) which. which 代指 playing cards at home or taking a walk in the park 作(in) 的宾语。

翻译成中文：你更享受花空余时间在在家玩牌还是到公园散步？这样可以吗？

回答如下

(1)  不能填动名词形式，要填动词不定式作目的状语.

原因如下：

(1)因为enjoy 的宾语是特殊疑问代词which

(2)to spend your spare time是动词不定式作目的状语

(3)我们可以把句子变换以下

To spend your spare time, which do you enjoy , playing cards at home or taking a walk in the park

(4)which 疑问代词是需要在后面2种选择种作出其中的一项选择.

(5)句子结构 sb enjoy sth to do sth 某人喜欢某事去做某事.

特别备注：enjoy的宾语是特殊疑问代词which（which 指代后面2个选择之中的其中一个选择，选择1=在家打牌；选择2=在公园散步

（1）enjoy+which

（2）which=2选1

（3）to spend your spare time 目的状语
