选择题
Since the forest has been destroyed by a big fire, a large ______ of trees ______ to be planted on the mountain．
A．number; has
B．amount; has
C．quantity; have
D．sum; have
答案
答案：C
第一空考查短语的用法：tree是可数名词，可以用a large number of或a large quantity of修饰，如果是A项，第二空应该填have，C项正确，因为a large quantity of后面修饰可数名词复数谓语用复数。选C。
