:用there be句型造句

　　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?
