1.答案:A.
2.翻译:你喜欢哪一种(方式)来度过你的业余时间,是在家打牌呢还是在公园里散步呢?
3.
1)此题关键是分析句子的结构.
which做enjoy的宾语,逗号后面是供选择的范围:playing cards at home or taking a walk in the park.
2)所以spend your spare time不是enjoy的宾语,后面只能填入to spend your spare time,用这个不定式短语做句子的目的状语.
3)如上解释,spend your spare time不是enjoy的宾语,所以排除B(enjoy doing sth);
在此句中用have your spare time不通,而且它也不能做enjoy的宾语,排除C;
to have spent...为不定式的完成形式,表明该动作发生在enjoy之前,错误,排除D.
