胡志鹏是我的同班同学，他不仅学习好，长得也很帅。
Hu Zhipeng is my classmate. He not only studies well, but also looks very handsome.
他那微微上翘的嘴唇使人感到格外亲切，觉得他始终是微笑的。
His slightly upturned lips made people feel particularly kind and he always smiled.
但是有时候他也会愁眉苦脸。比如他遇到难题时，总会记得满头大汗，只见他一会儿翻翻公式，一会儿在草稿纸上演算几下。直到最后把难题算出来，他的脸上才会重新露出微笑。
But sometimes he looks sad. For example, when he encountered a problem, he would always remember sweating, only to see him turn over the formula for a while, and perform several calculations on the draft paper for a while. He didn't smile again until he finally figured out the problem.
