我最近的作业。

This is for school work, so please if my words are grammatically correct, I should leave them alone! Only corrections of incorrect Chinese please. (Of course suggestions are welcome but please can we make sure I know they are just suggestions lol，thank you）

SPECS:
You hear that your friend Xiaoming (小明) is unwell, but you do not know what
is wrong with him. As he is new to the city in which you live, write an email to
him in Chinese characters to show your concern and give him some advice.
Write between 80 and 100 characters (advisory length).You should include the following information:
! Start with your friend’s name and a greeting.
! Ask what is wrong with him.
! Find out if he has a temperature or a bit of a cold.
! Tell him that you do not feel well either today.
! Tell him what your problem is (e.g. toothache, stomachache) and
what you are going to do about it (e.g. see a doctor).
! Advise your friend to go to see the doctor at the First
Hospital.
! Tell him that the First Hospital has both western and Chinese
doctors and that they can prescribe Chinese medicine.
! Advise your friend that he should drink plenty of water and
rest well.
! Say that you are going to see him tomorrow.
! Say goodbye.

小明，你好。

我听说你很不舒服，知道是哪里不舒服吗？（怎么了和哪里不舒服有点重复）是感冒了呢还是发烧了呢？（轻的病放在前面，重的病放在后面，表示递进的关系）
我今天头疼，肚子疼，也觉得很不舒服。（如果是今天的话，可以省略今天两字）下午要去看医生。

推荐你（如果是朋友的话，称呼就不要用您了。advise一个医院时，用推荐比较好，推荐用于sth，建议用于do sth）去第一医院看病。那里有西医也有中医（一般都不直接说有什么医生，而是说中医和西医）。 他们可以给你配中药。（prescribe=配药， Chinese medicine=中药，prescribe Chinese medicine = 配中药）
建议你多喝水，好好休息。（这里的advise就翻译成建议了，因为是要do sth）
我明天会去看望你。（看见只表示看到一个人的样子，去见一个病人不只是要看他一眼这么简单，要用看望，表示要见面并安慰他）
再见。

If the day you flight is in or near holiday, DO NOT TAKE TRAIN, it will be a large number of people taking train in those days. As I haven't got enough information and don't know which the city you leave is, i have no idea how long the trip would take. You can check China domestic flight in the site below http://english.ctrip.com/ The flight from Beijing to Shanghai takes about 2h. On the other hand, the fastest train from Beijjing to Shanghai takes about 10h. Of course you should go to Shanghai by plane.

如果具体到某个食物上。通俗的说就是吃sth吃撑了。表示吃的太多而肚子难受。 比如 He sat stuffing his face full of cake and crisps. 他吃蛋糕和薯片吃撑了。

It happpens sometimes. In Chinese, some words have more than one tone. For example 好 if you say it hǎo, it will be a adj, means good. if you say it hào, i will be a verb, means like.
