1. A.
   Leaving; to invite
2. B.
   Leaving; inviting
3. C.
   To leave; to invite
4. D.
   To leave; being inviting

Answer 1

B
试题分析：考查动名词做主语和固定用法。本题第一空leaving your car unlocked outside在句中做主语，第二空考查了固定词组mean doing sth意味着做某事；mean to do sth想要做某事；句意：让你汽车没有锁就放在我们意味着自找麻烦。故B正确。
考点：考查动名词做主语和固定用法
点评：动名词可以在句中做主语，谓语动词用单数形式。Mean有两个固定用法mean doing sth意味着做某事；mean to do sth想要做某事；在平时要加强识记和辨析。
