The river through our city ,which is about ( ),is clean again .
A.6000 metres long B.6000-metres-long
C.6000-metre-long D.6000 metre long

解答

A
解析 The river is long.变成 The river is 6000 meters long.
这里6000 meters 是一种程度,用来修饰long
6000-meter-long是一个复合形容词,用来做定语
比如 a 6000-meter-long river那行写成THE river is 6000-metre long 呢？不行，这种复合形容词是做定语的..,不能做表语
