话题：成为大学记者对我的影响
I have been a staff writer for the school newspaper, the Dagligtale, since my first day here at the University of Alberta. I probably won’t work as a journalist（记者） after my graduation, but this doesn’t mean my experience in student journalism has been useless. In fact, I have picked up many important skills through this job.
I still remember my first news story. It was about the victory of the school baseball team. I attended the celebration and was told to do some interviews. I was frightened（害怕）. Talking to strangers was one of my fears（恐惧）. But I gathered my courage and did it. I talked to the students, the players and the team leader. It was something I had never dreamed of doing before. This opportunity gave me confidence and helped me to improve my social skills.
In journalism, everything has to be based on facts. As a student journalist, I have learned to do research and to think critically about what I read. Discovering the facts is important when you are writing for the school newspaper, but in the Information Age, this is also an increasingly useful skill in everyday life.
As a student journalist, I always know that I have a lot to learn. I’m never afraid of asking people for feedback. I have learned how not to take negative（负面的） feedback personally and how to use it to make improvements to myself.
Journalism is a stressful field to work in, but I’m thankful that I have had the opportunity to try my hand at it. It has taught me to be a better storyteller, student and citizen. If you are ever given a chance to write for a campus newspaper or magazine, take it and learn everything you can!

B. talk about her experience of interviewing strangers

D. encourage students to work for a school publication
话题：大脑的故意遗忘
Some people are very forgetful, while others can remember everything they have done. Scientists know a lot about how our brains store and remember facts and experiences. There is little research on how or why the brain forgets things.
A new study looks at forgetting. A team of researchers from the US studied the brain＇s process（过程）of forgetting things. They studied the brain and how it thinks and works. Their work may help people who have memory problems. It may also help those with depression（抑郁症）and dementia. The lead scientist， Marie Banich, said, “It may sound surprising that people can control wat and how they forget.*”
Professor Banich said forgetting is important. She said it keeps the brain working smoothly. Her research found ways that people remove information from their brains. She said, “We have control over the ability to remove information from our thoughts. This is important because it means we can focus on more important tasks. However, although we can control what and how we forget, the act of forgetting needs a lot of effort." Another researcher, Sara Festini, agreed. She said，“We＇ve found that intentionally（有意地） forgetting useless information from the mind is good，but it doesn＇t happen automatically（自动地）.”Researchers will now look at why we forget recent events, like where we left our keys.
