11、掌握 when引导时间状语从句的用法? 3 学会运用 because 引导的原因状语从句? 4 there beThere be 句型用法总结There be 结构是英语中陈述事物客观存的常用句型，表示 “有”，其确切含义是 “存在 ”htere 作为引导词，本身没有意义，用动词be 的某些形式作为谓语动词，它的主语是用一些表示泛指或不定特指的名词词组，动词 be 和 主语的数必须一致。句子最后通常为表示地点和时间的状语。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 Itali

12、an 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。一、 There be 结构中的主谓一致1. 当动词 be 后所接的名词是单数可数名词或不可数名词时，be 应该取单数 is；当其后所接的名词是复数的可数名词时， be 用复数 are。Theres a man at the door.门口有个人。There is some apple juice in the bottle. 瓶子里有些苹果汁。There are some strangers in th

13、e street. 大街上有一些陌生人。2. 如果 There be 后面是几个并列名词做主语时，动词be的形式和最靠近它的那个名词保持数的一致。There is an ashtray and two bottles on the shelf. 架子上有一只烟灰缸和两个瓶子。There are two bottles and an ashtray on the shelf. 架子上有两个瓶子和一个烟灰缸。二、There be 结构中的时态1.

15、the table.桌子上一定有些蛋糕。There used to be a hospital there before the war.战前，那里曾经有家医院。3.
