Five Things Nobody Told Me about College

As I type this , I am in my university dorm room. A year ago, when I was awaiting to hear the results of my college applications, I often went to websites for some type of  insider look on what college would be like. However, there’s only so much that prep books, websites, and older friends can teach. Here are the top 5things nobody  told me about college:

Nobody entering a university knows  exactly what they want to study. If they tell you otherwise, they’re lying and will probably change what they want to purse  within the first quarter of attendance . During my first quarter at University of California, Riverside (UCR),I  thought that I wanted to study Political Science with its focus on International Affairs, so that’s what I  applied for. However, once I worked with statewide and local government, I realized that a better fit for me would be Public Policy, and now I am in the process of changing my area.

In college, there are so many good chances for you to meet your expectations. However, there is a very important difference between wanting to do something and applying for something. In order for you to take advantage  of the conferences, research, internships ,and fellowships that your university offers, apply! Step into your academic advisor’s office, introduce yourself, and begin making the valuable connections that are necessary to help during the rest of your college career. Great things happen when you step out of your comfort zone, and you would be surprised on how many chances exist if you just ask.

College is where you meet your birdesmaids,  neighbors, and potential bosses. The relationships you develop now will probably be linked to the ones you value later, so he wise about the people who you invest yourself in . You are only one person, and you do not have time to waste on people who would rather cause drama or mess up with your purpose. Surround yourself with uplifting individuals who challenge you to be better while loving you for who you are, and be patient  to the people who are the complete opposite of that description.

As a first-year, I was afraid to make any noise towards campus issues that I noticed. It was not until I became involved in student government that I gained the confidence to handle projects that I created with the help of ASUCR Office of the President. During my first quarter, I spoke directly to the Chancellor, asking him for support towards my initiavives, met with the Vive Chancellors, and coorerated with my teaching assistances to begin my undergraduate research protect. Nothing good will happen when you are silent.

At my high school,there were about only four active club and organizations that students could be a part of.Imagine my surprise when I stepped foot onto UCR’s capus,where over 400 organizations exist,ranging from political organizations to karate club.You are not paying all or your tuition(学费)to merely go to class,study,pass tests and graduate.Make something worthy out of your experience.Create that you will want to tell your grandchildren one day.It all begins here,by signing up to join an organization.

63（）

A. Get involved in student activities

B. Your voice is actually super important

C. There is a significant increase of opportunities

D. Stay in active communication with your friends

E. Get smart about the people who you spend your time with

F. Your major does not matter as much in your first of college

如图（a）所示，水平面上有两根很长的平行导轨，间距为L，导轨间有竖直方向等距离间隔的匀强磁场B₁和B₂，B₁和B₂的方向相反，大小相等，即B₁=B₂=B．导轨上有矩形金属框abcd，其总电阻为R，质量为m，框的宽度ab与磁场间隔相同．开始时，金属框静止不动，当两匀强磁场同时以速度v₁沿直导轨匀速向左运动时，金属框也会随之开始沿直导轨运动，同时受到水平向右、大小为f的恒定阻力，并很快达到恒定速度．求：

（1）金属框所达到的恒定速度v₂

（2）金属框以恒定速度运动时，单位时间内克服阻力所做的功

（3）当金属框达到恒定速度后，为了维持它的运动，磁场必须提供的功率

（4）若t=0时匀强磁场B₁和B₂同时由静止开始沿直导轨向左做匀加速直线运动，经过较短时间后，金属框也做匀加速直线运动，其v-t关系如图（b）所示，已知在时刻t金属框的瞬时速度大小为v_t，求金属框做匀加速直线运动时的加速度大小．
