Answer 1

1. B
at play在玩耍中；起作用的 in play 开玩笑地；比赛进行中；现行的
by accident 意外地；偶然地 on purpose 故意的 by mistake 由于差错，错误地 for fun 开玩笑的，为了好玩
2. A
第一个空increase"增加"和raise“使…上升”都讲得通 increase by/raise by+分数/百分数表示“增长到”
第二个空用that引导宾语从句，从句中不缺任何成份，所以用that,不用what
3. A
a large/huge amount of表示大量的=large/huge amounts of可接不可数名词或可数复数 a number of只接可数复数
The cost of living 生活开销
4. B
dead 为adj，be+adj系表结构
die为.vi, died与had同为过去时形式,看连词如and是解题的一种方法
death为.n
