There are
there is
a couple of+n(c).作主语时谓语动词通常用单数
它有两个含义
1.两个
e.g.There is a couple of boys waiting for you.
2.一些，几个
e.g.I don't know why I feel so tired, I only had a couple of drinks.
是There is,因为一对是单数
there is
用 there is
此句若没有a couple of, 光有boys当然用there are.
但冠词a 限制了复数形式的使用，因a表示的是“一...”。所以只能用there is 了。
