问题：选择题,急,帮帮忙.Asaresultofdestorythef 
As a result of destory the forests a e ______of desert ______ corered the land   A number has Bquantity has C number have D quantity have                      
回答：选 B. 
首先排除C.D. 因为have 与 desert矛盾
a large number of = a lot of =lots of + 可数或不可数 n.
a quantity of + n.+ 动词的单数形式
a quantities of + n.+ 动词的复数形式
( 看出来了吗? 动词的形式决定于quantity的形式)

以下单词是不是打错了?
lange----large
corered---covered
