重点句型过关
1.表达( 某地) 以前没有某物的句型：
There was n library in my ld schl.我以前的学校里没有图书馆。
There were n cmputers r Internet in my time.
我那时候没有电脑也没有互联网。
用法：这是用来描述以前没有某物的句型。是There be 句型的一般过去时的否定形式。
句型结构：There was/were n + 某物+ in + 某地+ 某时.
2.请求对方讲述关于某方面的信息的句型：
Tell us abut yur schl, please.
请给我们讲讲您的学校吧。
解析：此句用于请求某人讲述关于某方面的信息，是一个祈使句。abut 是介词，意为“关于”，后接想要知道的信息。
句型结构：Tell + sb. + abut + 其他.
祈使句表示请求、命令、叮嘱、邀请、劝告等，朗读的时候一般用降调。其否定形式是在谓语动词前加Dn't。
e.g.
(1) Tell us abut yur daily life.
给我们讲一讲你的日常生活吧。
(2) Dn't be late fr schl.
上学不要迟到。
3.询问对方如何知道某事的句型及答语：
—Hw d yu knw that? 你怎么知道的？
—I lked it up n the Internet. 我在互联网上查的。
解析:问句用于询问对方是如何知道某事的，hw 意为“怎样，如何”，用来询问方式，that 用于指代上文中提到的事情。回答时可以直接说明知道的方式或途径。
句型结构：Hw + 助动词+ 主语+ 动词原形+ 其他?
4 描述某人过去和现在的不同的句型：
Befre, I was quiet. Nw, I’m very active in class.
以前我很安静。现在我在课堂上很活跃。
I was shrt, s I culdn’t ride my bike well. Nw, I g cycling every day.以前我个子小，自行车骑得不好。现在我天天骑自行车。
用法:此句型用于描述同一个人或事物现在与以前的变化。描述过去的
情况，要用一般过去时，描述现在的情况，要用一般现在时。
可以从以下几个方面进行描述：
(1) 外貌和性格方面：
Befre, 主语+ was / were + 形容词. Nw, 主语+ am / is /are + 形容词.
Befre, I wasn't tall. I was quiet. Nw, I am tall. I am active.
以前我不高，很安静。现在我很高，很活跃。
(2) 能力方面：
