(1)我的钢笔和【你们俩的】 / 【你们三人的】 一样译文:My pen is the same as yours.解释:英文中your和yours两个人以上都可以指。就象we,our一样可以指两人也可以指多人。如果要特别强调二人则为:My pen is the same as both pens of you two.或者My pen is the same as both pens of you two.如果要特别强调三人则为:My pen is the same as each pen of you three.或者My pen is the same as everyone of you three.(2) 他的情况和你们两个不一样。译文:The situation of his is different from both of yours.(3) 我的车 比你们俩 / 你们三人 的要贵 My car costs more than both cars of you two(两人).My car costs more than every car of you three(三人). My car is the most expensive car in our four cars.(4) 他的爱好和你们都不相同译文:His hobby is different from both of you two(两人),His hobby is different from every hobby of you three(三人)。希望能帮到您。祝您进步。
