人教版初中英语英语语法专项温习之there be句型备考点 No. 1there be 句型基本熟悉 1.定义：There be句型示意某处存在某物或或人。 2.构造： (1) There is +单数可数名词/不可数名词+ 地方状语 (2) There are +单数名词+地方状语 留心事项：there是 指导 向导词，在句中不充任任何成分，翻译时也不必译出。句子得主语是或人或某物，谓语动词be要与主语（或人或某物）得数坚持一致。当主语是两个或两个以上得名词时，谓语动词要与跟它比来得哪个名词一致。如： ① There is a bird in the tree.   树上有一只鸟。 ② There is a teacher and many students in our classroom.  我们教室里有一位先生和许多学生。 ③ There are two boys and a girl under the tree. 树下有两个男孩，一个女孩。 No.2 there be 句型得常考点 考点一：各种句型转化 1.变成否认 There be句型得否认式得组成和含有be动词得其它句型一样，在be后加上not或no便可。留心not和no得不同：not是副词，no为形容词，not a/an/any + n. 相当于no+ n.。例如：  There are some pictures on the wall. →There aren't any pictures on the wall. =There are no pictures on the wall.  There is a bike behind the tree. → There isn't a bike behind the tree. =There is no bike behind the tree. 2.变成一般疑问句 There be句型得一般疑问句改变是把be动词调整到句首，再在句尾加上问号便可。但同时要留心：当一定句中有some时，要将其改成any（否认改变也一样）。 There is some water on Mars. → Is there any water on Mars? There are some fish in the water. →Are there any fis
