READY or not, the college application season has begun. There are two main kinds of early admissions programs: Early Action and Early Decision.

    Early Action is a great choice for the well-prepared student. Students apply early, and are allowed to apply under an Early Action program to as many colleges as they choose. The biggest advantage for students is that colleges let them know early – in most cases, before Jan 1. Roughly 15 percent of colleges and universities offer an Early Action option(选择). Oct 15 is now the first deadline for many colleges and universities. This movement toward earlier deadlines is especially popular in the Southeast, with many of the large public universities leading the way. North Carolina State University, the University of South Carolina and the University of Georgia all have an Oct 15 Early Action deadline.

    Early Decision is a promise that cannot be reversed. Students who are accepted must take back their other applications and should attend that school. Students are allowed to apply to just one school under an Early Decision program. Early Decision deadlines are in early November, with colleges letting students know by mid-December. Many students believe that they are more likely to be accepted if they apply for Early Decision, but it actually depends.

       In some cases there is big increase in students being accepted, and at other colleges it is not that big at all. Generally, the strongest students are applying early. Athletes and students with focused interests are encouraged to apply for Early Decision.

已知曲线C的极坐标方程是ρ=2cosθ，以极点为平面直角坐标系的原点，极轴为x轴的正半轴，建立平面直角坐标系，直线l的参数方程是$\left\{\begin{array}{c}x=\frac{\sqrt{3}}{2}t+m\\ y=\frac{1}{2}t\end{array}\right.$（t为参数）

（1）求曲线C的直角坐标方程和直线l的普通方程；

（2）当m=2时，直线l与曲线C交于A、B两点，求|AB|的值．

新课程实施以来，有些学校取消了晚自习，你所在的班级学生对是否取消晚自习展开了一次讨论。请结合以下讨论内容用英语写一篇短文，并发表自己的看法。
