there be是一种固定的句式表示‘有’的意思
这里的BE动词是用is或are及用单数还是用复数则要看名词的单复数
如：there is a bear.(a bear是单数所以用is)
there are some bears.(some bears是复数所以用are)
当有两个名词或两个以上时,则根据就近原则,即看靠近be的那一个名词的单复数
如：there is a bear and foxes.(a bear是单数所以用is)
there are foxes and a bear(foxes是复数所以用are)

There _____a book.[isn't ,aren't] There _____any books.[isn't ,aren't] There is/are 后动词要加ing,那么there isn't/aren't 后呢 There isn‘t any book There aren’t any books there must be 反意疑问句什么时候用aren't there 什么时候用isn't?有什么区别?
