a large number of /many+[c]
a great deal of /much+[u]
lots of/a lot of+[c]/[u]
a large/great number of(= many) 后显然加可数名词(这样理既然已经用了"number"当然接可数名词啦^_^)
a great deal of(= much) + 不可数名词
lots of和a lot of后都可以加
a body of,bodies of,quantities of+名词作主语时的主谓一致,例如:
Large quantities of water ____ needed to plant the trees in this area.
A.is B.are C.have D.has
选择B
主语中心语为quantities,谓语应用复数.
