be动词单复数的确定，看be后边第一个名词，当所接主语为单数或不可数名词时，be动词形式为is;当所接主语为复数名词时，be动词为are;当be动词后接两个以上主语时，be动词与最临近主语保持数上的一致。意思为"某地有某人或某物"。如：
There is an eraser and two pens on the desk.桌子上有一块橡皮和两支钢笔。
There are two pens and an eraser on the desk.桌上有两支钢笔和一块橡皮。
(1)ther ebe的否定句，即在be的后面加上not。
否定形式为：There be+not+(any)+名词+地点状语。
There is not any cat in the room.房间里没猫。
There aren‘t any books on the desk.桌子上没书。
(2)therebe句型的疑问句就是将be提到句首：Bethere+(any)+名词+地点状语
肯定回答：Yes，thereis/are.否定回答：No，thereisn’t/aren‘t.
-Is there a dog in the picture?画上有一只狗吗
-Yes，there is.有。
-Are there any boats in the river?河里有船吗
-No，there aren’t.没有。
(3)特殊疑问句：How many...are there(+地点状语)
某地有多少人或物回答用There be...
There‘s one./There are two/three/some...
有时直接就用数字来回答。One./Two...
-How many students are there in the classroom?教室里有多少学生
-There’s only one./There are nine.只有一个。/有九个。
(4)如果名词是不可数名词，用：Howmuch+不可数名词+isthere+地点状语
How much water is there in the cup?杯中有多少水
How much food is there in the bowl?碗里有多少食物
