Dear Dad,
School is really great, i am making lots of friends and studying very hard. With all my stuff, I simply can't think of anything I need.
So if you would like, you would like, you can send me a card, as i would love to hear from you.
Love,
your son

Dear son,
I know that astronomy economics and oceanography are enough to keep even and honor student busy. Do not forget that the pursuit of knowledge is a noble task, and you can never study enough.
Love
Your Dad
问: 儿子为什么要写信?
父亲给了儿子所需要的了吗？
　 With all my stuff, I simply can't think of anything I need. 这句话是什么意思？

儿子说：学校这边不错！我交了很多朋友，学习也很用功。我这什么都有，什么都不缺。要是你愿意的话，就给我寄张明信片，这样我也好知道你那边的情况。
爸爸说：我知道那些天文学啊，经济学啊，海洋学的，足够学习好的学生忙乎的。别忘了，学习知识是一项神圣的任务。学无止境。
