Answer the questions  （根据以下内容回答问题）

Do you think you’re a lucky person? Let’s see what Professor Richard Wise-man, a famous psychologist（心理学家）, has discovered about luck:

Ten years ago, I set out a research on luck. I wanted to know why some people are always in the right place at the right time, while others always experience ill luck.

Many people volunteered for my research. Over the years I interviewed them, watched their lives and had them take part in my experiment.

I carried out a simple experiment to discover why there were differences in their ability to find opportunities. I gave both lucky and unlucky people a newspaper and asked them to look through it an tell me how many photographs were in side.

I had secretly placed a large message halfway through the newspaper saying. “Tell the researcher you have seen this and win $50.”

This message took up half of the page and was more than two inches high. It was staring everyone straight in the face, but unlucky people tended to  （倾向于）miss it and lucky people tended to spot it.

Unlucky people are just more nervous than lucky people. They are busy looking only for what they need and this stops them from noticing the unexpected. As a result, they miss out on opportunities.

Lucky people tend to be more relaxed and open. They can see everything that is in front of them, rather than just what they are looking for.

My research shows that lucky people live by several principles（原则）. Here are some of these principles:

1.Opportunities are always given to those who are prepared.

2. Be open to new experiences and break your normal thought patterns（模式）.

3.Spend a few moments each day remembering things that went well.

4.See yourself being lucky before an important meeting or phone call.

1.How long has Professor Richard Wise-man studied on luck?

2.What did the volunteers do for the professor during the research?

3.What’s the purpose of Professor Richard Wise-man’s small experiment?

4.The message in the newspaper was so small that unlucky people couldn’t find it, wasn’t it?

5.Why did the unlucky fail to find the message in the newspaper according to the research?

6.Which principle of the four is the most important in your opinion? Why?
