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(zhǔn)備了5個口罩,。從飛機上下來,，離開達(dá)拉斯機場候機樓時，我正準(zhǔn)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(xué),，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(xué)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(xué),。

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,。
