so详细用法归纳如下

so既可用作副词，又可用作连词，表示“这样”、“如此”、“因此”、“所以”等意思。现简述如下：

【一】so作副词用，意为“这样”、“如此”，常用来代替整个句子或某一情况的全部，在口语中常与think, hope, say, be afraid等词语连用，表示客气、委婉的答语。

 — ' Well, I hope so.'

“他是那种能够灵活变通的人吗?”“嗯，希望如此。”

【二】so作连词用，意为“因而”、“所以”、“为了”、“以便”等。

【1】so为并列连词用法，引导表示原因关系并列句“因此，所以”

天晚了,所以我们回家了。

狗饿了,所以我们喂它。

注意：用英语表达“因为……，所以……”时，用了because就不能再用so，用了so就不能再用because。请注意下面汉语句子的英语译法： 

因为他病了，所以没去上学。

误：Because he was ill, so he didn't go to school.

正：Because he was ill, he didn't go to school.

正：He was ill, so he didn't go to school.

【2】so为从属连词用法，引导目的状语从句状语从句。

他挽起她的手臂，带她匆匆上了楼，这样别人就听不见他们说的话了。

【三】so用作副词，在句中可以修饰形容词或副词。 

【1】so表示程度，意为“这么”、“那么”、“如此地”。 

When he came back, I was so tired.

当他回来的时候，我疲劳极了。

【2】so常用于口语，意为“非常”、“很”。

五分钟前我在我的包里找到了它。

【3】在“so+助动词/be动词/情态动词+主语”的倒装结构中，表示前面所述的肯定情况也适合于后者。

我英语学得好，我妹妹学得也好。

我喜欢英语，她也喜欢。

He is nice, and so is she.

本句中，and 是并列连词，so 是副词，意为“同样，也一样”，修饰动词（is）。is的表语是nice，承前省略，不是so。

I don’t know his address, and neither do I want to know.

I enjoy dancing, and so does my wife (enjoy dancing).

注意：在这一结构中的主语可以是名词或人称代词，但它和上文的主语不是同一个“人”或“物”。

—She bought a computer.她买了一台电脑。

—So did I.我也买了一台。

另外，这一结构的否定式是“neither/nor+助动词/be动词/情态动词+主语”。

—He doesn't know Lin Tao's address.

他不知道林涛的地址。

—Neither do I. 我也不知道。

这里的neither/nor意为“也不”或“也没有”。

在较文的文体中，有时候在 as 可用倒装（跟 so 的用法相同）。如：

She’s very tall, as is her mother.

她个子很高，她母亲也高。

I voted Labour, as did my wife.

我投了工党的票，我妻子也是。

She was very religious, as were most of her friends.

她宗教信仰很深。她的绝大多数朋友也是这样。

备注：as=and so

在很正式的文体中，as后面有时跟助动词+主语：

She was a Cathollc, as were most of her friends.

她是个天主教徒，她的朋友也大都是天主教徒。

He believed, as did all his family, that the king was their supreme lord. 他和他全家的人一样，相信国王是他们至高无上的主。

如今，针刺疗法在世界各地很受欢迎，其他的传统中医疗法也是一样。

【4】在“so+主语+助动词/be动词/情态动词”结构中，so用于对前面事实的肯定，有“的确如此”之意。

—He will go to Hangzhou for a holiday tomorrow.

他明天要去杭州度假。

—So he will.的确如此。

 “He will go to Hongkong.”“So he will.”
“他将要去香港。”“是的,他将去。”

注意：这一结构中的主语和上文中的主语通常是同一个“人”或“物”。

—It's her turn now.

现在轮到她了。

—So it is!是呀！

【5】在“主语+do（动词某种形式）+so”结构中，so用以避免重复前文提到的情况。

老师让我们读这篇课文，我们就读了。

【6】so+形容词/副词+that引导结果状语从句
