so是什么意思（每日经典考点4：so句型分析）
so是英语中常用的一个词，它既可以作代词，又可用作副词，在中学英语中由其引起的句式结构较多，现归纳分析如下：
一、百思特网 so作代词时，用来表示前面提到的相同的人，物，事情或情况，常构成下列句式。
1、 so+be(助动词或情态动词)+主语，这一结构用来表示前面所说的情况也同样适用于另一个人或物，意为 in the same way。
（主语已经换成另外的主语，倒装）
The boy died and a week later so did his sister.
I am an English teacher.So is my wife .
但若前面所提到的人或物是两个或两个以上的句子，并且其中既又肯定句，又有否定句；既含实意动词，又含系动词；主语既有表示人的，又有表示物的。这时应用“So it is (was) with”的句式。
Tom studies English well ,but he isn't good at maths.So it is with Kate.
汤姆英语学得很好，但他不擅长数学。凯特也是这样。
Wang lin is a Chinese girl ,and China is her homeland.So it is with me.
王琳是个中国女孩，中国就是她祖国。我也是这样。
2、so + 主语 + 动词，这一 结构用来表示对上文的情况给予进一步的肯定或确认。（主语还是那个主语，不倒装）
—It was cold yesterday.
—So it was.
—The students study hard.
—So they do .
—He went to college last year .
—So I have heard.
3、主语+动词+so，这一结构意为照前面所说的做了某事或认为，希望，恐怕上文所说的事会发 生。
(1) 主语+do (does,百思特网did)+so
He said he would tell me the news,but he did not do so .
他说他会告诉我这个消息，但他没有告诉我。
(2)主语+hope (expect,think ,百思特网believe ,suppose ,imagine ,be afraid) + so
—Do you think his will come ? —Yes ,I think so.
你认为他会来吗？-是的，我想他会来的。
—Will it be fine tomorrow?—I hope so.
明天天气好吗？-希望如此。
注：在用这一结构来代替否定概念时 ，既可用so，亦可用not，在动词believe，expect，suppose，imagine，think 等的肯定形式后加not与否定形式后加so，两者在意义上没有区别。但在hope，be afraid 后代替否定概念时只能是not，而不能用so。
—Will he come here ? —No,I suppose not .(No,I don't suppose so.)
他会来这里吗？-不，我想他不会来。
Are we starting that again? I most sincerely hope not.
我们又要旧事重提了吗？我真的希望不要。
