改错不懂!The problems that are created by environmental contamination are very hard to resolve.
我总觉得这句话不通,为什么第一个are可以要呢?可不可以讲that后面的那个are去掉呀?
书上原题是:The problems that are created by environmental contamination is very hard to resolve.
然后改为这:The problems that are created by environmental contamination are very hard to resolve.
可是我觉得改过的也不懂,总觉得第一个are怪怪的,还有that是个什么从句呢?如果是从句,那第一个are在句子中是什么成分呀?
that不可以去掉,但是可以同时去掉that are 这样created就是相当于个形容词,不做谓语成分了.前面的that是定语从句的标志.
