询问几道初高中英语语法的题

____food is kept in his new cave.
A.Large quantities of B.A great deal of
C.A large number of D.Quite a few
此题选B,其他三项都修饰可数名词,此外不可数名词作主语时谓语动词用单数
trousers 什么时候谓语用单数或复
trousers作主语时,用复数,与pair连用时要视pair的单复数而定
即：a pair of trousers要用单数,two pairs of trousers就要用复数
Many a man___come to help us
此题要用单数,虽然many a man在语意上表示复数“许多人”,但此题遵循语法一致的原则,要与a man保持一致,所以用单数
What we need ____good textbooks
此题要用复数,虽然主语从句作主语时,谓语常用单数,但此题是主表一致的原则,表语是复数,主语也是复数的概念,所以谓语动词用复数
What tou said just now____the matter we are discussing.
a.have something todo at
b.has something to do with
c.had something to do with
d.has been something to do with
B,就是上题说的常用情况
