Have you ever imagined what bees can do with their tiny brains? Now scientists are looking into a bee’s brain.

Clint Perry, a scientist, has spent much time studying how bees think. He says studying bees is not very different from studying other animals. “The main difficulty is to design(设计)an experiment(实验)bee and get what we want,” he says. “With humans, we can ask them a question and get an answer. But we can’t use the same way to get an answer from bees. They are just trying to get sugar. Bees like sugar.”

The fact that bees like sugar is helpful for scientists to design experiments. For example, in one experiment, Perry gave bees a task: to find delicious sugar on a landing place above a black bar(棒). Perry made the task easier or harder by moving the landing place farther from or closer to the black bar. He found that bees would avoid the task when it was difficult. And when the task was easy, bees would try it.

As for humans, we might choose not to take a test when we weren’t ready for it. And we might choose to take the test when we were well prepared. In the same way, bees seemed to make decisions like humans.

Perry points out that we are not sure whether bees actually make a thoughtful choice from experiments. Now scientists still do not know how bees manage to do so much with their tiny brains. But learning more about how bees’ brains work could help us learn more about how our own brains deal with information.

Some people think only school children do not agree with their parents, however, it is not true.
Communication is a problem for parents and children of all ages. If it’s hard for you to communicate with your parents, don’t worry about it. Here are some advice for you to bridge the generation gap (消除代沟).
Don’t argue (争辩) with your parents. Don’t get to your parents when you are angry. Your parents probably won’t consider your ideas if you are shouting at them. And you can’t express yourself well if you are angry. Go someplace to cool off. Make sure you understand why you are unhappy. Then think about what you want to say to your parents. If you don’t think you can speak to them at the moment, try writing a letter.
Try to reach a compromise (和解). Perhaps you and your parents disagree on something. You can keep your disagreement and try your best to accept each other. Michael’s mother didn’t agree with him about buying a motorcycle. They argued over it. But they finally came to a compromise. Michael bought the motorcycle, but only drove it on certain days.
Of course, your parents might refuse to compromise on something. In these situations, it is especially important to show love and respect (尊敬) to them. Showing respect will keep your relationship strong.
Talk about your values. The values of your parents are probably different from those of your own. Tell your parents what you care about, and why. Understanding your values might help them see your purposes in life.
A good relationship with your parents can make you a better and happier person. It is worth having a try!

It is well-known that the “prom”, a formal dance held at the end of high school or college, is an important date in every student’s life. What is less well-known is that the word “prom” comes from the verb “to promenade”, which means to walk around, beautifully dressed, in order to attract attention. The idea is that you should see and be seen by others.
The prom is not just an American tradition, though most people believe that it started in America. In Canada the event is called a “formal”. In Britain and Australia the old fashioned word “dance” is more and more frequently being referred to as a “prom”. Most countries have some form of celebration when students finish high school: after all, it means the end of life as a child, and the beginning of life as an adult.
The prom is expensive to organize and the tickets can cost students a lot of money. The tradition is that students themselves have to raise the money to pay for it. Selling the students newspapers is one way to raise money; so is taking a part-time job at the weekend.
Although the prom should be the experience of a lifetime, it also worries many students. There is the problem of what to wear, who to take as your partner, who will be voted “prom queen”, etc. And it is not only students who feel worried. What many parents find difficult is the realization that their children’s school days are almost over. However, for most people at the prom, once the music starts playing, everyone relaxes and stops worrying.
In which country is the prom called a “formal”?

A.America. B.Canada. C.Britain. D.Australia.

Why is the prom important in the students’ lives?

A.It’s the sign of becoming an adult.
B.It’s an old tradition in many countries.
C.There are many problems to work out.
D.The students can raise money by themselves.

What is the passage mainly about?

A.The history of the prom.
B.The traditions of the prom.
