　　非常荣幸能在马里兰大学2017届毕业典礼上演讲。

　　People often ask me: Why did you come to the University of Maryland?

　　人们经常问我：你为什么来马里兰大学?

　　I always answer: Fresh air.

　　我总是回答：清新的空气。

　　Five years ago, as I step off the plane from China, and left the terminal at Dallas Airport. I was ready to put on one of my five face masks, but when I took my first breath of American air. I put my mask away.

　　五年前，从中国来的时候，我准备了5个口罩。从飞机上下来，离开达拉斯机场候机楼时，我正准备戴上口罩时，吸入了第一口美国的空气，然后我将口罩收了起来。

　　The air was so sweet and fresh, and oddly luxurious.

　　这里的空气是那么的清新甜美，显得格外的奢侈。
