跨过高考的大道，我选择了计算机这一门专业，刚接触到第一门语言是我也是感到陌生，自己有怕问老师，就感觉学的特别吃力，讲师知道了我的情况后，主动与我交谈，帮我解答问题，他告诉我，学计算机不与其他专业，这是一门操作能力很强的语言。如果不懂就要多问。
经过这一年的努力学习，我的进步很大，在学校参加过各种编程大赛，取得了优异的成绩。
我认为作为IT员工应该具备一下特点：
1.要有团队合作精神，一个人的力量是渺小的，但是团队的力量是巨大的。
2.要有良好的职业道德和素养，这是具备程序员的基本准则。
3.不懂就要问，这是程序员自主学习的潜能。
说明一下，我还在读大二
，在校期间我们小组创作了许多作品：
下面就看看我的结业项目吧;
