1.good 是形容词,而 well 是副词
他说英语说得跟她一样好
He speaks English as well as her.
His English is as good as hers.
2.用法
as well as
（1）as well as构成同级比较结构，意为“和……一样好”。这时，第一个as是副词，第二个as是连词，引导一个状语从句，表示同级比较。
He speaks English as well as a native speaker.他讲的英语是和英语是母语的人一样好。
（2） 如果as well as连接的是两个简单动词形式，它和第二个动词实际上起着插入语的作用，这时as well as后的动词在人称和数上应与主语保持一致。
as good as
（1）as good as用于字面义，表示“与……一样好”，可视为as…as结构与good的自然搭配；若用作习语，则表示“几乎”“无异于”“实际上”
（2）搭配，其翻译不能随便从字面来理解：
(as) good as a play 非常有趣
(as) good as gold 表现很好的
(as) good as new 完好如新
as good as one’s word 守信
as good as pie 很好的，可爱的，讨人喜欢。

1.在A as well as B的结构里，语意的重点在 A，不在 B。因此，“He can speak Spanish as well as English．”的译文应该是：“他不但会说英语，而且会讲西班牙语”，决不能译作：“他不但会说西班牙语，而且会讲英语”。如果这样翻译，就是本末倒置了。
2.as well as和 not only… but also…同义，但前者的语意重点和后者的语意重点恰好颠倒。
如果 as well as用作连词引出比较从句，其义为“和…一样好”。因此，“He speaks Spanish as well as English．”应译作：“他说西班牙语像说英语一样好”。语意的重点依旧在前部，不在后半部。
注意 as well as以下的用法：
She called on you as well as I．
不但我来看你，她也拜访了你。
She called on you as well as me．
她不但拜访了我，也拜访了你。
在下列句中，as well as表示“像…一样”的涵义：
She as well as you is an English teacher．
她像你一样也是英文教师。
这里的谓语动词用is，不用are，因为句中的主语是she，不是she和you。
as good as…意思是 相等于，就像，几乎如；实际上，其实，实在。
例句:
A brave fellow is as good as his words, a swift horse needs no spurring.
勇者一言，快马一鞭。
A change of work is as good as a rest
调换一下工作是很好的休息
A miss is as good as a mile
失之毫厘,谬以千里
他说英语说得跟她一样好.
正：He speaks English as well as her.

2. 用于引申义,两者的意思很不相同：
(1) as good as 意为“几乎”“差不多”(=almost).如：
He as good as said I’m a liar. 他无异于说我撒谎.
We’re as good as ruined. 我们差不多完蛋了.
习语be as good as one’s word意思是“说话算数”.如：
You’ll find that she’s as good as her word. 你能了解到她这个人很讲信用.
(2) as well as 表示“而且”.如：
She’s clever as well as beautiful. 她不但漂亮,而且聪明.
He speaks Spanish as well as English and French. 他不仅会说英语和法语,而且会说西班牙语.
该结构强调的重点是在前面一个词（体会以上例句的译文）.如：
A as well as B=not only B but also A
该结构连接两个成分作主语时,其后谓语通常与前面一个主语保持一致.如：
Mary as well as her friends is going to Paris. 玛丽和她的朋友要去巴黎.
与动词连用,动词通常要用动名词.如：
As well as breaking his leg, he hurt his arm. 他不但摔断了腿,而且还伤了胳膊.
He sings as well as playing the piano. 他不但会弹钢琴,而且会唱歌.
有时也可与主句动词的形式一致或用动词原形（但均不如用动名词常见）.如：
As well as eating [ate, eat] a seven-course meal, they drank three bottles of wine. 除吃了一顿有7道菜的饭之外,他们还喝了3瓶酒.
具体到这两句话,第一句用as well as连接she和you,但是侧重点是前者,说的是she,所以后面的be 动词是用的is.
第二句用as good as,是属于“几乎,差不多”的意思,“这个人躺在地上几乎像死人一样.”
