正在选一个新的中文名

我上了九年级的时候，我被我中文老师得了一个中文名。在那里的中文课，如果学生不是华人的话，他们需要有一个听起来中文的名字；就是说一个用汉字的名字。如果老师访问你或者你想回答一个问题的话，老师用你的中文名。唯一的问题是，我那时讨厌这个名字而且现在还讨厌。我中文名比我现实的名听起来很像的，不听起来自然。当有人听到我中文名，他们马上知道我是外国人。很多我同学们笑话我难听中文的名字。因为我八月会上大学，所以我想选一个全新的中文名。

我有一个问题（跟这个话题关联的）：“卓”的发音是一声还是二声吗？我昨天看了到一些网站来发现。一半说“卓”字是一声而且一半说“卓”是二声。我困惑得一点。

When I was in 9th grade, I was given a Chinese name by my Chinese teacher. In Chinese classes there, if a student wasn't Chinese, they had to have a name that "sounded" Chinese; in other words, a name that used Hanzi. If the teacher called on your or you wanted to answer a question, the teacher would use your Chinese name. The only problem is, I hated my name back then and I still hate it to this day. My Chinese name and my actual name sounded similar and it didn't sound natural. If someone heard my Chinese name, they would immediately know that I was a foreigner. Many of my classmates made fun of my weird-sounding name. Because I'm going to university in August, I want to choose an entirely new Chinese name.

I have a question (that's related to the topic): Is "卓“ pronounced with the first tone or second tome? I looked at a few websites to find out yesterday. Half said that it was the first tone and half said it was the second. I'm a bit confused.
