知识拓展: there be句型。
构成: There be ...句型表示的是 “某处有(存在)某人或某物”，其结构为There be(is，are，
was, were)+名词+地点状语。e.g.
There are fifty-two students in our class.
There is a pencil in my pencil-case.
否定句：There be句型否定句式的构成和含有be动词的其它句型一样，在be后加上
“not”。也可用“no”来表示。即: no + n.（名词）= not a\an\any + n.（名词）。注意: no + n.（可数名词单数）= not a\an + n.（可数名词单数）；no + n.（可数名词复数）= not any + n.（可数名词复数）；no + n.（不可数名词）= not any + n.（不可数名词）。e.g.
There is an orange in her bag.
→There isn’t an orange in her bag.
→There is no orange in her bag.
