there be 句型的就近原则就近的是后面所跟的名词性成分 就你所说的题应该用there are 这里的there are修饰的是books而不是a variety of a variety of 则是另一个修饰books的词组 还原回来 你也可以这样理解 a variety of books are there 你不可能说a variety of books is there 吧 而且……there be句型的就近原则应该是更体现在有两者以上 比如:there is some milk and books on the table there are some books and milk on the table
