1.I recently had an----with George---current affair
a appointment,about b discussion,againist
key:b 关于时事我们有过讨论, appointment 意思是约会,指定

不是应该discuss about sth吗?可以用againist 来替换?

3.How surprised I was--- so many bridges in that town?
a to see b to seeing
这里把i放回去不是 I was surprised to see so many.........吗?
key:b

那这里的答案为什么是b呢??a怎么不可以??

8 DNA---by forensic scientists or the police can be traced back to an individual.
a discovered b recovered c founded d covered
key:b
discovered 发现 recovered 复原子核 founded建立 covered盖
为什么选b阿

题确实有问题。
