昨天天气很好，今天天气也很好！
我练习了我的汉语：读汉语，写汉字，说汉语，等等。   我今天练习了汉语（in Chinese， when we say "I practised my Chinese language"， we do not add “我的”，just saying “练习了汉语” is fine.）
这个大学的图书馆非常繁忙。这个大学图书馆很多人（when we say the library is busy， we usually say“图书馆里很多人” instead of “非常繁忙”， it's not wrong but we hardly use “繁忙” to describe the library is busy. ）我们不久有考试。很快我们就要考试了。（when we describe we have an exam soon， we usually usu “考试” as the verb instead of "有"， and use "就要" means very soon ）四月二十号，有一个汉语口语考试。 

现在，我想要去买一杯咖啡。 

That‘s my suggestions， hope they can help u.

(English: Yesterday's weather was great, today's weather was also great!
I practised my Chinese language：reading Chinese, writing Chinese characters, speaking Chinese and so on.
The university library is very busy. We have our exams soon. On April 20th I have my Chinese oral exam.
Now, I think I will go buy a cup of coffee.)
