1.基本结构 There be + 主语 + 地点/ 时间状语.如：There is a computer in the room.房间里有一台电脑.There are two TV plays every evening.每晚有两场电视剧.2.主谓一致 要采取就近一致原则,和靠近 be 的主语一致.如：There is a pen,two rulers in the box.盒子里有一只钢笔,两把尺子.There are two boys and a teacher at the school gate.门口有两个男孩,一个老师.3.主语后的动词形式 在there be 句型中,主语与动词是主动关系时用现在分词；是被动关系时用过去分词.如：There is a purse lying on the ground.地上有一个钱包.There are five minutes left now.现在还有5分钟.4.反意疑问句.反意疑问句应与 there be 对应,而不是依据主语.如：There is a radio on the table,isn't there?桌子上有一台收音机,是吧?There are more than fifty classes in your school,aren't there?你们班有50多名学生,是吧?5.there be 与 have 的替换 there be 表示所属时可与 have 替换.There is nothing but a book in my bag.= I have nothing but a book in my bag.包里只有一本书.6.there be 后接不定式时常用主动形式表示被动意义.如：There is a lot of work to do.有许多工作要做.注意：当该句型主语是 something,anything,nothing 等不定代词时,后面的不定式用主动形式或被动形式,意义各不同.There is nothing to do.没有事可做.There is nothing to be done.没有办法(束手无策).7.与其它词连用,构成复合谓语.如：There may be a rain this afternoon.今天下午可能有雨.There used to be a cinema here before the war.战争之前,这儿有一家电影院.8.变体 there be 结构中的 be 有时可用 live,stand,remain 等代替.如：Once there lived a king who cared more about new clothes than anything else.从前有位国王喜欢新服胜过别的任何东西.9.习惯用语 There is no good /use (in) doing sth.做某事没有好处/用处；There is not a moment to lose.一刻也不能耽误.例如：There is no good making friends with him.和他交朋友没有什么好处.He is very ill.Send him to hospital.There's not a moment to lose.他病得厉害,把他送到医院去,一刻也不能耽误.
