一道SAT语法题目麻烦大家解释一下,谢谢!

before he sprained his back, Morgan had spended much of his leisure time (engaged) in outdoor sports, paticularly hiking and canoeing.
这里为什么engaged是对的?不是engaging?

"before he sprained his back, Morgan had spended much of his leisure time (engaged) in outdoor sports, paticularly hiking and canoeing."

1. I don't think this is the original sentence.

2. If it is, the book or test from which this sentence is lifted is NOT written by a native speaker
of English.

3. If the book or test IS written by a native speaker of English, s/he is NOT a specialist.本回答被网友采纳

使这个因素如此孤立
夜色转浓,仿佛隔板慢慢关好,
而我发热于一场美梦。
不再拥有它 我们是谷壳,看见
是一支小曲。一支歌引领我
彼此,却都坚然的么你的的存在哈哈本回答被提问者采纳
