我对你学校有那么大感到非常吃惊,在这里没有这么大的学校.并且在大学校里评分的主修课大约有三或五个,每科平均有三十个同学.这里,在巴西,我们每周去五天学校,从周一到周五,然后我们也在周末放假.早上7：45学校开始上课,12：15下课.我们通常学葡萄牙语,英语（我英语不好,这就是我上英语课的原因）,数学,艺术（绘画）,化学,物理,地理,历史,生物,文学,宗教和体育,并且由学校决定——因为分数不同——上哲学或心理学.在这里,所有年级上一样的课,没有选择,没有艺术课或科学课.所有同学接受同样的教育,这样很不好.因为没有创造出一个大学的观念,这是一个大问题.……当你上完高中的时候,不知道大学该怎么办（或文理学士学位）……我们会有一个用于课程挑选的测试……如果你做得不好,有很多问题,你就需要参加差不多大约30门课程,你必须通过20门考试才能得到学位证明,这非常困难.
现在我在上大学（文理学士学位）,我学国际贸易,现在有很多改变,你选择自己的课程,上你所希望的课程数.每门课程由你的分数决定.用8个学期上5、6门课,每学期你需要登记,每个班平均50个同学.在这学期,比如说,我在上两门课,因为我在私立大学,所以这非常贵!我在学国际贸易的入门课程和人事管理,我的课程以管理经营为基础.
在过去,我想学医药,但我的科学学得不好,主要是医学和化学.我选择这样的课程是因为我想学数学,我喜欢了解别的文化.我主要喜欢亚洲和欧洲.中国和意大利是我的梦想.我喜欢几乎所有食物,人.这太美好了,梦幻一般.除此之外城市也很好.
我太喜欢你了,因为我们喜欢很多同样的东西,我们有很多共同之处.
我也喜欢旅游,巴西是个很漂亮的地方.有很友好的人,非凡的海滩和自然景色.我住在巴西南部,这是一个有亚热带气候的地方,有时很冷、有时很热,很像欧洲国家.
我写诗,这是我的爱好,我不想作莎士比亚,但人们认为我写得好（如果你愿意,我可以给你看看）.
你想学葡萄牙语吗?我的国家使用这种语言,它很像西班牙语.
你认为我们将来互相写信怎么样?也可以互发信息（通过手机）.
终于翻译完了……是巴西朋友吗?有一些拼写和语法错误呀.
