课文讲解ago的用法ago用作副词，意为“以前”，在句中不能单独使用，它的前面必须要有一个表示时间的词或词组，ago词组用于一般过去时。ago的常见短语two weeks ago 两周以前
three years ago 三年前
a few days ago 几天前
a long time ago 很长时间以前there be 句型句中的there’s 相当于there is，其中there不是指“那里”或“在那边”，而是与is一起构成there be 句型,表示“（某处）有某物或某人”。它的基本句型为：
There be (is/are)+主语（人/物）+其他.注意:
①该句式中只有一个主语，主语为单数或不可数名词时，be动词用is；主语若为复数，be动词用are。
例如：
There are many hills in the park.
公园里有很多座小山。②该句式中有几个并列主语，则谓语动词按就近原则处理，即与靠近be动词的第一个主语保持一致。
例如：
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。Find the mistakesIn the Tang dynasty…At that time, there were no gyms. People didn’t go by bus . People couldn’t use the Internet.
