这边天气总是变来变去，一不小心就感冒了。这时不得不跟老师发email请个病假了。在email的开头，当然要亲切称呼老师为Dear professor啦。然后清晰地介绍自己是哪门课哪位学生，讲诉自己生病了，有多严重，打算休息几天，若是生病期间有作业必须要交，可以请求老师延迟自己交作业的时间或是以email方式上交。最重要的是，在email中应该附有doctor notes表明你是真的病了，一定得按时吃药，不能弃疗!!

Hi, Professor Obama,
I am Lei Li, one of your students from Math 101-1 class. I have been preparing for the first midterm by doing practices from the study guide. However, I am still very confused about some of the concepts we have learned. Would you be available for office hour appointments tomorrow? I am free _______.
例如：I am free all of wednesday,and if you dont have any time available that day, i am also free thursday andfriday after 3pm
Iam Lei Li, an international student from China. Last Thursday, I took the assessmenttest for Physics and my result was 78%. I know that in order to take Physics1118, the required grade needs to be greater than 80% and my grade does notqualify. I really like physics and I've taken up to Physics 12 in China. Iwould love to continue to expand my knowledge about physics by taking this courseand other courses in the future. Would it be possible for me to take Physics1118?
Please reply when you can. Thank you for your time.
