【题目】When I was 5, my father worked the night shift as a nurse in a hospital. He was always carrying his stethoscope (听诊器) so naturally, so I called him “Dr. Saldivar” while I pressed his stethoscope against his chest. But my father, as a humble man, was always correcting me: “I am not a doctor, son, but you can be one.” I grew up feeling like I had no limits because of moments like this, which has helped me take risks personally and professionally in spite of the hardships I had to endure.

Being born to Mexican immigrants meant that my parents had to work very hard to provide for my family and I had to learn to struggle through school paperwork on my own, because my parents’ English was limited and they couldn’t always be there motivating us through the process. If I wanted to succeed academically, my perseverance, and strength would be tested.

Perseverance, strength and good education are the gateway to success. And this is especially true when you look at the obstacles that Latinos have to overcome to succeed in public schools. For instance, while the national high school dropout (辍学) rate has decreased significantly, we still have the highest dropout rate in the country. We are more likely to live in poverty and attend racially separated schools. These issues create many other problems for Latinos.

To help relieve my family burden, I found my first job when I was 14 at a local hotel. Despite the long hours on my new job, I worked hard. Meanwhile, I continually stressed the importance of getting a respectable education and did everything possible to get one step closer to making my dream a reality.

Nearly a decade later, I became the first in my family to graduate from the University of Southern California. Knowing the social, economic, and political struggles that a community faces, I began to pursue journalism to give the disadvantaged minorities a voice.

A conflict at work is common. If you can avoid conflict, it means you will win what you want regardless of what the other person wants. Since the potential problem has not been removed, it will simply reappear later
Be aware of the fact that some conflicts are unavoidable at work. On many occasions(场合), conflict and disagreement are likely to happen. But when a conflict happens it is not the end of the world.Conflicts mean that people care enough to disagree strongly. The trick is not to allow the conflict to go on forever.
Solve a conflict when it starts, as it only gets worse with time going by. Everyone is waiting for the other to admit he or she is wrong and gets more unpleasant after the conflict has lasted a while. It is necessary to interrupt the "waiting game" before it gets to that point.
Ask nicely. If somebody has done something that makes you angry, or if you don't understand their viewpoints or actions, simply asking nicely about them can make a world of difference. Never assume that people do what they do to annoy or hurt you. Sometimes there is a good reason why that person does what he or she does, and a potential conflict disappears right there.
Appreciate.Tell them why it is worth it to you to solve the conflict. This can be difficult as few people find it easy to appreciate a person they disagree strongly with, but it is a great way to move forward.
A. Praise the other part in the conflict
B. Deal with conflicts sooner rather than later.
C. Invite the other person to talk about the situation.
D. Do remember to make an enquiry, not an accusation of any sort.
E. Here are the necessary steps to effectively get rid of conflicts at work
F. On the contrary, it can be the beginning of an interesting learning process.
G. Clear thinking is unlikely to happen while an argument continues to boil over.
