Unit2单元语法精讲精练 there be 句型 1. 含义及结构 there be 句型的结构一般为“there is/are + 主语(某物/某人)+ 地点”,表示某地有某物,也可以表示某地有某人。 2. 用法 - 当主语是可数名词单数或不可数名词时,用 there is - 当主语是可数名词复数时,用 there are 例: - There is an apple on the desk. 桌子上有个苹果。 - There are many students in the playground. 操场上有很多学生。 - There is still some water in the cup. 杯子里还有一些水。 3.句型的否定和疑问形式 如果要表达某地没有某物或某人,或者询问什么地方是否有某物或某人,就要用到 there be 句型的否定和疑问形式。在 there be 句型中,从句法结构上讲 there 为主语,所以其一般疑问句形式是将 be 提至 there 之前,构成 is there/are there 的句式,而否定形式是在 be 后面加 not(可以缩写)。 举例如下: - 肯定句:There is a computer on the desk. - 否定句:There isn't a computer on the desk. - 一般疑问句:Is there a computer on the desk? - 回答:Yes, there is. / No, there isn't. - 肯定句:There is some food on the table. - 否定句:There isn't any food on the table. - 一般疑问句:Is there any food on the table? - 回答:Yes, there is. / No, there isn't. - 肯定句:There are some students in the playground. - 否定句:There aren't any students in the playground. - 一般疑问句:Are there any students in the playground? - 回答:Yes, there are. / No, there aren't. 注意: 1. 当 there be 句型的主语是由 and 连接的并列成分时,be 动词要和离它最近的主语保持单复数的一致,这就是“就近原则”。 例: - There is a book and two rulers on the desk. 桌子上有一本书和两把尺子。 - There are two rulers and a book on the desk. 桌子上有两把尺子和一本书。 2. 对 there be 句型中的数量进行提问时,通常用 how many (多少)。 单元语法精练 一、阅读下面句子,用 be 的正确形式填空 1.
