答案是B,但我认为不能说sth is a kind of.......应说sth is that of a kind of sth
sth 不能和一类事物并列作者: primefang 时间: 2002-9-4 09:47
原句的意思是, A is not B , rather a kind of C
D> 中that 没有指代对象.
而且,that of a kind of 感觉上罗锁作者: brigittew 时间: 2002-9-4 15:40
sth is a kind of is correct usage here, seldom see the usage of that of a kind of sth, awkward expression
