都是就近原则,即BE与最靠近它的名词一致,如
There is a book ,two pens and three pencils in the bag .
There are two pens ,a book and three pencils in the bag .
Here is a book for you .
Here are some flowers for you .
加油!不明白再问!最后打错了是There doHere do的用法，举例子，谢谢了这两个是构成倒装句，如There goes the bell .Here comes the bus .the bell ，the bus 是单数所以用单三如果是the bells ， the buses 就是There go the bell .Here come the bus .吗？如果是the bells ， the buses 就是There go the bells .Here come the buses .
