这是2010年NECCS试题:
翻译:
当david的年龄是现在年龄的两倍的时候,他的年龄是他的女儿jane五年后年龄的四倍.如果在1990年(四年前),他的年龄是他女儿年龄的四倍,jane是什么时候出生的?
1983年 令现在david年龄x,他的女儿jane的年龄y,则2x=4(y+5)对吧?因为现在是1994年(而不是2010年),所以根据第二句话有:x-4=4(y-4),则根据以上两个方程求出y=11,x=32 则在1994年也就是现在他爸爸34岁,他女儿11岁,则女儿出生在1983年
不知道是不是你标点有点问题,我翻译感觉有问题,还是先写出来吧。。。 当大卫比现在的他年长两倍时,他将比他的女儿年长4倍(Jane是他的女儿嘛?就是这里纠结,下面直接接1990那里),如果是1990年,即4年前,他比他的女儿年长四倍,他的女儿是什么时候出生的呢?
ps:你结合一下原题应该能揣摩清楚题意了,不知是水品不够还是你标点问题,我翻译不顺,但是大意应该不错,希望对你有帮助。...

要自己会才行
楼下的翻译的是错误的
