第26部分(第5页)

equations,

you will find the values of x,y,z, and the sum of these would be your

answer

to the problem。 I think the solution is

x = 60,  y = 36,  z = 32

So the answer to your problem is

x + y + z = 128

Since you are only 12, I suppose you are still in elementary school and

have not

learned about systems of equations。 In that case, it is unreasonable to

ask

you to solve such problems。

With best wishes,

J。 Li 我一看——啊,全英文的哦!我不禁挠了挠头。

但是很快我就发现,大部分我都能看懂,只有几个专业词语查了字典。我的中文翻译如下——亲爱的悉妮:

谢谢你的美妙的e-mail。但我不知道怎么打中文,

希望你会读英文。

那么,

有一个标准的方法解决你的数学难题。让x、y、z 分别代替大米、小麦、黄豆的袋数。那给出的条件是一定的。在三个变数x、y、z中有一个规律的三个等式。解决这个等式的方法,你将发现x、y、z的值,求出和,得到答案。

对于这个难题。我想解决方案是:

x = 60,  y = 36,  z = 32

所以你的难题答案是:

x + y + z = 128

因为你只有12岁,我猜想你还在上小学,没有学过方程式,在那个情形,这样的难题给你解决是不合适的。

最好的祝愿

J。 Li可是,对这道难题,我发觉我仍然有不明白的地方。于是,我又用自己的“中国英文”给励教授回了一封信,希望他能详细给我讲解一下。我的英文e-mail如下——Dear J。Li,

Thanks for your nice revert! Im studying English now。 I can read English。 Dont worry, please。 My parents hope I can speak in English and mastery English。

Ill dialog for you in English now。 But my English isnt very well。 Please you point out mistakes so that they can be corrected, and teach me English, and teach me English sentences grammar, ok?

Thanks for you help me solve problem! Im very happy!

Excuse me, I cant say this “您说得没错”in English。 Will you teach me it? I can but with “Its right” replace “您说的没错” now。

Its right, Im 12 years old。 But Im already finish elementary school。

This problem certitude is unreasonable, since I in school not study it。 I dont opt, too。 Excuse me, I cant talk this sentence in English“毕竟是初中升学考试?
