在英语中有一个结构是“as..... as ”,可以翻译为“和...一样”。“as good as”这个短语从字面意思来看，即是“和...一样好”。但是，在以下短语中，“as good as”原由网却与其本来的意思大相径庭。我们一起来学习一下吧！
Your guess is as good as mine .
Guess 意思为猜测，猜想。这句话的本意为“你的猜想和我一样”。
不过这个习惯用语的意思是 you do not know anymore about a subject than the person that you are talking to .也就是 "我和你一样不知道"、"我和你一样心中无数"。
例句
A: "Where s Mr. Smith?"
B: "Your guess is as good as mine.
He didn t say anything to me."
史密斯先生在哪？
我也不知道，他什么也没和我说。
我们再来拓展两个同义短语来表示“我也不知道”。
01、not have a clue
You don t have a clue when
that meet原由网ing starts, do y//www.58yuanyou.comou?
你也不知道那场会议什么时候开始，是吗？
02、it beats me
It beats me—I //www.58yuanyou.comreally have no idea
how to get to the library from here.
这可难倒我了-我真不知道从这如何到达图书馆。
as good as gold
As good as gold means to behave very well，especially a kid.
As good as gold 的真实含义是“规规矩矩，很乖，表现好”，特别用来指代小孩子规矩的言行。
例句
①She s been as good as gold all morning .
她一上午表现都很好。
②The children are all as good as gold when visiting the old people s home.
在拜访老人之家的时候，孩子们的表现非常好。
03、as well as的用法
as well as常用来连接两个并列的成分，作“也，还”解。它强调的是前一项，后一项只是顺便提及。因此连接并列主语时，谓语动词与前一项一致；而用not only ...but also...连接时，谓语动词与后一项一致。如：
①Your wife as well as you is friendly to me.
不仅你而且你的妻子也对我很友好。
（＝Not only you b//www.58yuanyou.comut also your wife is friendly to me、）
② Electric energy can be changed into light energy as well as into sound energy.
电能既可以被转变成声能，又可以被转变成光能。
as well as 用来表示同级比较，指“一样好”。如：
① You look as well as you did ten years ago.
你的身体看起来还和十年前一样好。
② He plays the guitar as well as you.
他的吉他弹得和你一样好。
