There be的句型,如there is no doubt that...

【1】There be 是英语中常用句型,意思是“有”,表示“人或事物的存在”.There在此结构中是引导词,已经没有副词“那里”的含义.There be 后面的名词是句子的主语,属倒装结构.其问句形式是将be或will/have/can/must等助动词、情态动词提至there之前,否定形式则直接在be或助动词、情态动词后加not,因此要表达“某个地方或某个时间存在什么事物或人”的时候常用“There be + 名词+ 地点（时间）这一句型.例如：
There is a great Italian deli across the street.
穿过街道,有一家大的意大利熟食店.
There are some students in the dormitory.
在宿舍里有一些学生.
【2】举例　　
There is a train coming now.
There are two dogs in the garden.
There weren"t any people in the park yesterday.
There won"t be another footbool match next Sunday.
There have been some changes since you left last week.There is a book on the desk.
There can"t be anything new.
Must there be an indefinite article here?
Is there going to be a post office in the village?
there isn't

告诉你几个简单的常用句：
there is no doubt that 毫无疑问
there is no need to do不需要做某事
there is no point in doing 没有意义做某事
