There be 句型的疑问句
一.There be 句型的一般疑问句There be 句型的一般疑问句变化是把be动词调整到句首，再在句尾加上问号即可。但同时要注意：当肯定句中有sme时，要将其改为any（否定变化也一样）。看看下面两句是如何“改头换面”的吧
二，There be句型的特殊疑问句There be 句型的特殊疑问句形式有以下三种变化：1.对主语提问：当主语是人时，用“Wh's+介于短句？”；当主语是物时，用“What's+介词短句？”注意：无论原句的主语是单数还是复数，对于提问时一般都用be的单数形式（回答时却要根据实际情况来决定）。
2.对地点状语提问：提问地点当然用“Where is/are主语?"！例如：There is a cmputer n the desk.（桌子上有一台电脑）Where is the cmputer？（电脑在哪里？）
3.对数量提问：一般有两种句型结构： Hw many+复数名词+are there+介词短语？ Hw much+不可数名词+is there+介词短语？
A: Hw many birds are there in the tree?
B: There are three.
1. There _____ ______ ______ stamps n the envelpe .(以否定形式完成句子)2. There were sme trees ten years ag. （变为否定句）__________________________________________
There were nt any trees ten years ag.
