The sky cleared up this morning, after breakfast, I left the refectory for the teaching building. In this morning, I only had the course heat transfer, it’s an interesting class I like most this semester, which tell us how heat is  transfered and it can be used in our daily life. I learnt that interval of the glass to enjoy the sun is warmer than directly absorbing the sunshine, the clapboard on the air conditioning should face the floor when heating the room, and face the ceiling when cooling the room, etc. And more importantly, the teacher is very funny, she often told us jokes and stories, in addition, she often makes the difficult and abstract questions easy to understand. Today she told us she dreamed to a writer(作家) which meant she can stay at home all day(整天坐在家里），and  once an employee wanted to work for the Microsoft, the hr asked “how much is operation system of WIN7 in the market, he answered “five yuan”.Very funny, wasn’t it? And I get to think about that heat transfer is not only a science, but also a guide for us to make people warm and happy.

 In the noon, I had a snooze under the sun and then we had a course called automatic control theory which is  hard to learn and I did two exercises for a long time, fortunately the answer is not bad. As it’s Friday today, after class, I, with two of my friend went to ZiWei100 to have our supper by bus. The food and drinks are very good, the atmosphere and service are also not bad, we ate a lot of meat, especially the delicious mutton. We talked and ate with great fun. After nearly two hours, we went back against the big belly.

In the evening, I watched a moive named Dongchengxijiu2011, it was a hilarious moive and a little touching. Then I feel like writing something to leave a mark on today, then here comes the above dull words.
