There is...的表达。引导学生了解周围事物的变化，渗透中国的历史文化的学习，同时保持学习英语的兴趣，激发学生学习英语的热情以及树立学习英语的信心。第一课时是本单元的基础课时，要让学生重点把握知识，为学习其他课时打下良好的基础。本课时的的重点是四会单词、短语的掌握以及能够运用四会单词和短语描述某个地方的过去和现在。 本课时是新授课，词汇、对话比较简单，容易理解和接受，在设计教学过程时，让学生课前收集一些和本课有关的资料，拓展文本，重在应用。采用的教学方法有情境教学法，听说训练法，迁移运用法等。

There be 句型
there be句型表示“某处有某物或某人”。该句式中be动词的单复数形式取决于句子的主语：
主语
主语为单数名词或不可数名词
例如：There are many hills in the park.
公园里有很多座小山。
主语为复数名词
be
is
are
eg: There is a blackboard, many desks and chairs in the classroom. 教室里有一块黑板、一些书桌和椅子。
eg:There are many desks and a blackborad in the classroo. 教室里有一些书桌和一块黑板。
句中有几个并列主语，谓语动词采用“就近原则”，即与靠近be动词的第一个主语保持一致
