I always answer： Fresh air,。

我總是回答：清新的空氣,。

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,，從中國來的時候，我準備了5個口罩,。從飛機上下來,，離開達拉斯機場候機樓時，我正準備戴上口罩時,，吸入了第一口美國的空氣，然后我將口罩收了起來,。

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

這里的空氣是那么的清新甜美,，顯得格外的奢侈,。

I was surprised by this。 I grew up in a city in China,， where I had to wear a face mask every time I went outside,， otherwise， I might get sick,。

我深感意外,。我在中國的一個城市長大，從小出門都得戴口罩,，否則就會生病,。

However， the moment I inhaled and exhaled outside the airport,。

然而,，在機場呼吸到這里空氣的那一刻。

I felt free,。

我感受到了自由,。

No more fog on my glasses， no more difficult breathing,， no more suppression,。

我的眼鏡上不再有霧，呼吸不再困難,，也沒有了壓抑,。

Every breath was a delight。 As I stand here today， I cannot help,， but recall that feeling of freedom,。

每一口呼吸都是愉悅的。今天我站在這里,，仍然忍不住回想起那種自由的感覺,。

At the University of Maryland， I assume feel another kind of fresh air for which I will be forever grateful — the fresh air of free speech,。

在馬里蘭大學,，另一種清新的空氣也令我感懷不已——言論自由的空氣。

Before I came to United States,， I learned in history class about the Declaration of Independence,， but these words had no meaning to me— Life， Liberty and the Pursuit of happiness,。

來美國之前,，我在歷史課上學到了獨立宣言，但“生命,、自由和追尋幸?！边@些詞句對我而言毫無意義。

I was merely memorizing the words to get good grades,。

我僅僅是背下這些詞句以期在考試中取得好成績,。

These words sounded so strange， so abstract and so foreign to me,， until I came to University of Maryland,。

這些詞句顯得那么古怪，那么抽象,，那么陌生,，直到我來到馬里蘭大學。

I have leaned the right to freely express oneself is sacred in American,。

我終于明白,，言論自由在美國是多么神圣。
