There be 主要用来表示“某地有某物”。
There be句型中be的形式随着后面的名词变化而变化,当be后面接的是单数可数名词和不可数名词用is;
There is a book on the desk.
There is some water in the glass.
当be后面接的是复数可数名词用are。
There are some books on the desk.
当be后既有单数名词也有复数名词,要用就近原则。
There is a book and three pens on the desk.
There are two books and a pen on the desk.
