第二节:阅读下面短文,第61至65题表述了Anna、Smith、Wilkins、Crick和June在自己的生活及学习中遇到的问题,他们需要你的帮助,请从A、B、C、D、E和F中为其选出最合适的建议,并在答题纸上将该选项标号涂黑。选项中有一项是多余选项。

61.Anna: I get really frustrated easily, and sometimes I end up yelling at people I love.I'm not very sure why it happens, but I have no control over it.How can I stop?

62.Smith: Some kids are making fun of me because I'm doing very well at school.Isn't that something to be proud of? I need advice.

63.Wilkins: I can't sociaize.I am really shy, and I am already a freshman in high school. I have some new friends, but I am still shy to the cool kids.Can you help me, please?

64.Crick: I always say what I feel immediately and without thinking.Sometimes I get in trouble for it or feel sorry about it later.Is speaking your mind a good or a bad thing?

65.June: I love to read! But I don't have any time to read because of all of my activities.I don’t want to quit anything.What should I do?

A

Instead of feeling upset, you should definitely be proud of yourself.Intelligence is a quality that everyone wants, and as you get older it's going to be what people love and respect about you.Still water runs deep.I'm sure as time goes by, some of those kids making fun of you might realize how cool you actually are.

B

Everyone has to leam how to adapt to society and mix socially with others.No man is an island, as the saying goes.To become a sociable person, you must be naturally friendly.Besides, do something for a social situation.A teacher once gave me this great advice: Prepare a conversation in your head before going into an uncomfortable social situation.It sounds like a lot of work, but it's easy and it works! Get involved in activities that interest you and you will make new friends fast.

C

Always keep a book with you so that you can read during pockets of free time.Turn some of your TV or computer time into reading time.Read for a little while right before bed, and find time to read on weekends.Also, talk to your parents about your schedule.You might not want to quit anything, but you might need to find more free time in order to have a happy balance in your life.

D

That feeling is your conscience, and it's telling you that you need to confess what you did.Be brave and tell your parents.Even if they get upset when they hear about it from you, they would be even more upset to hear about it from your friend's mom.So pick a quiet time and say.Mom, Dad, I need to tell you something, but I'm afraid.Then spill the beans.No matter what they say, you'll be relieved not to have this secret any more.

E

First, identify what is frustrating you, then learn to calm yourself down.The next time you start feeling frustrated, stop what you're doing and breathe deeply.Count to ten.Get up and walk around.Clear your mind before you come back to the frustrating task.If you keep a cool head, you'll be less likely to snap at others.And if you do yell at someone, apologize and admit that it's not that person's fault.Then calm down and try again.

F

Speaking your mind can be a really good thing.Far too many people don't, except when talking about someone behind that person's back.However, there are times when honesty does more than good like when a girl asks if she looks fat.So in situations in which there's no real good, you are better off keeping your thoughts to yourself.In situations in which that is not the case like when your brother asks if his breath stinks feel free to tell the truth.Just be prepared to take it in return.
