睡觉=go to sleep(it's more used as a verb,and means an act) 睡着=asleep / fall asleep(it's more like a status)

How could be you? (or Why you?)

I think i'll feel pity for a second,but it won't last for long.Anyway as it's my favorite language i'll keep doing practice,no matter take it just for interest or as a serious learning.Otherwise,it can't be called"favorite",isn't it?^ ^

First here is the chinese version for ur question^^ 1)“Today , one of my Chinese male friends asked "Why is it that men and women live together in American college dorms?"今天，我的一个中国男性朋友问我，“为什么在美国的大学，男女可以合住?(and you can also use"混寝"instead of the word"合住",it particularly refers guys and girls live together) 2)I replied "Is this strange? Is it not common in China?"我回答道，"这很奇怪吗？这在中国不常见吗？"(or you may make the 2 sentences into one,then it'll be"这在中国很奇怪吗？"although here u omit "common",but the phrase still indicates ur furthur question"Is it not common in China?",so u can choose any one as u like) 3)He went on to say that "In China, men and women do not live together in student dorms. They are separated."他接着说，"在中国，在大学里男女不能住在一起。他们分开住。"(went on=接着and usually we say"co-ed" as"男女",not "女男",this is just an idiom,no specific reason lol) Now is the answer for ur question^^ Here in China,co-ed dorms is rarely seen in universities.在中国，大学里几乎不存在男女合住。 Generally we seperate guys and girls dorms.一般男女都是分开住。 The roommates are uaually from the same class,or maybe from the same major.But sometimes maybe from different major or faculty.But the rule is still no co-ed.一个寝室的室友可能是一个班的，也可能是一个专业的。但有时候也可能是不同专业或是不同学院的。 Well u still got chance to live as co-ed dorm.不过你还是有机会选择男女混住。 You can live outside the university and rent a room as a co-ed dorms.你可以在校外租房子，选择男女混住。 But anyway in some university,probablly u have to get the approval for living outside the university,coz u r arrenged into a dorm since u entered the uniersity.But you can cancle it later.但是在某些学校，你可能先得得到学校批准才能在校外住，因为从你入学起就已经被安排好宿舍了。但是（如果你想住校外），你可以稍候选择退宿。 Well i once lived in university with a couple of girls through 4 years lol^^

seperately these 2 words can be understood the same meaning,not it doesn't work all the time.U should put it in the particular condition to choose the proper one.Generally,"suo3 you3 de" is used as an adjective,while"yi2 qie4" is more used as a noun.Here in this sentence"here, each computer is too expensive",when translated into Chinese,it can be"zhe3 li3 suo3 you3 de dian4 nao3 dou1 hen3(or tai4) gui4 le."Although there's no"dou1(=all ) exsits in the original phrase,but you put this word in your tranlated one,it makes the whole phrase more smooth and coherent.

描述 is much like the verb"state",to state something or a person,or maybe a situation.It can be used when u try to describe something to its original condition. 形容,well this word is also used when describe something or someone,but it emphasises the deature or the character. In general both these 2 words can be understood as"describe",but each emphasises different point,better combine with the particular condition for better understanding lol

表现 is more like "performance" in english,generally it was used as a nom,while 行为 is more close to the the word"behavior",it can be used both as a verb and a nom.
