i have the same dream as you还是i have the same dream with you .

as with 的用法有什么区别

应该是
I have the same dream as yours. 我和你做同样的梦。

as 表示“一样”的意思
with 是“和...一起“

如果想说“我和你一起做梦”，应该是
I dream with you.

i have the same dream as you 首先请你看一句话: Linda isn't as tall as Jenny. 这句话换个方式也可以这样说: Linda isn't the same height as Jenny. 现在我们用这两种说法把珍妮和琳达两个 姐妹作个比较. 在下面这组练习里有几个字你可能不太熟, 比方 "女用手提包" purse 和 "女衬衫" blouse. 这些字等一会儿我们还会重复练习. 现在我们开始 作语法练习. 请你注意听. M: Linda isn't as tall as Jenny. F: Linda isn't the same height as Jenny. M: Linda isn't as old as Jenny. F: Linda isn't the same age as Jenny. M: Linda's swimming suit isn't as expensive as Jenny's. F: Linda's swimming suit isn't the same price as Jenny's. M: Linda's hair isn't as brown as Jenny's. F: Linda's hair isn't the same color as Jenny's. M: Linda's skirt isn't as long as Jenny's. F: Linda's skirt isn't the same length as Jenny's. M: Linda's purse isn't as formal as Jenny's. F: Linda's purse isn't the same style as Jenny's. M: Linda's blouse isn't as big as Jenny's F: Linda's blouse isn't the same size as Jenny's. 现在我们来作代换练习. 老师先说一句话: This dress is the same length as that one. "这件连衣裙的长度跟那件一样". 接着老师给你一个字: style,你就把句子 改成: This dress is the same style as that one.老师也可能给你另外一个东西的 名称, 比方: "外套" coat, 那么你就应该把句子改成: This coat is the same length as that one. 好, 现在我们开始作练习.请你斟酌情况看看应该代换哪个字.每作 完一句,你就跟老师念的正确答案比较一下, 看你作对了没有. M: This dress is the same length as that one. M: style F: This dress is the same style as that one. M: purse F: This purse is the same style as that one. M: color F: This purse is the same color as that one. M: skirt F: This skirt is the same color as that one. M: price F: This skirt is the same price as that one. M: blouse F: This blouse is the same price as that one. M: size F: This blouse is the same size as that one. M: coat F: This coat is the same size as that one. M: length F: This coat is the same length as that one. 下面我们换一个方式作练习. 练习的内容还是提到百货商店里卖的东西, 比方 "一双短袜" a pair of socks, "一双女人穿的长袜子" a pair of stockings, "一条牛 仔裤" a pair of jeans, "一双靴子" a pair of boots 等等. 练习的作法是由老师提出 一个问题, 比方: Is this pair of socks the same color as that pair? 接着老师说: dark, 学生就用这个形容词的比较级作否定的答覆, 所以答案就是: No, this pair of socks is darker than that pair. 好, 现在我们开始作练习. 请你在学生回答问题 的时候也一起回答. M: Is this pair of socks the same color as that pair? M: dark F: No, this pair of socks is darker than that pair. M: Is this pair of stockings the same length as that pair? M: short F: No, this pair of stockings is shorter than that pair. M: Is this pair of boots the same price as that pair? M: expensive F: No, this pair of boots is more expensive than that pair. M: Is this pair of pants the same size as that pair? M: small F: No, this pair of pants is smaller than that pair. M: Is this pair of gloves the same style as that pair? M: formal F: No, this pair of gloves is more formal than that pair. M: Is this pair of glasses the same price as that pair? M: cheap F: No, this pair of glasses is cheaper than that pair. M: Is this pair of jeans the same length as that pair? M: long F: No, this pair of jeans is longer than that pair.

是 I have the same dream as you. 当表示“和...一样”时，the same ＋名词＋as，这是固定搭配，介词就用as，所以在这句话里，主要不是as和with的用法或意思的区别，而是固定搭配问题
