There are two shirts on the bed.,There be 句型变换,如果一个句子中有be的形式存在，那么这个句子的疑问或否定形式都在be本身变化，比如一般疑问句，只要把be动词提前，否定句就在be后面加not就可以了。 另外记住some用于可数名词单数及不可数名词，并且用于肯定句中。any用于不可数名词，并且用于否定句和疑问句。,口诀,There be句型不一般，主语跟在be后边。 be可变为is / are, there永远不变化， 单数主语用is, 复数主语要用are。 变疑问，很简单，be须大写来提前； 变否定，也轻松，be后not记心中； 肯定句中用some, 否定、疑问any用。 时间地点是状语，句子首尾任你选。,practice,请你变换刚才的三个句型，分别改成一般疑问句以及否定句。 There is a tie in the box. There are two shirts on the bed.
