But how to make them? How do you start? How do you get along with people? Here are five ways to help you to do these.

    Greet(闾候)people

    Greet people and hope that they have a good day - whatever time of day it is. It doesn't hurt any people. It also makes people think you're friendly.

    Share

    Take something to eat in your pocket. Ask if people would like to have some, and at the same time hand it to them.

    Help people

    Simple actions, like helping people carry something or opening a door show yourkindness.

    Smile

    Perhaps smiling is the easiest way to introduce yourself. There's a great reason why ittakes fewer muscles(肌肉)to smile than to cry. Nature just wishes us to smile more.

    Respect(尊敬)others

    The world's full of differences. So learn to respect others. It is the only way otherpeople will respect you.

根据材料内容简要回答下列问题。

    Some people seem to have unusual memories. Zheng Aiqiang, a "memory athlete" on TV show Super Brain, can remember 2,660 numbers in just one hour!

    You would think people like him must have special brains. But according to a recent study by researchers from America and Holland, the brain structure (结构) of ordinary people and 23 of the world's leading memory athletes shows no difference.

    Good memories can be trained. New research in the magazine Neuron suggests that a person will get a super memory with just six weeks of hard training.

    Researchers found that a technique (技巧) called loci, invented by the ancient Greeks, can greatly help improve memory.

    By using loci, you are using your imagination to improve the brain's memory networks. You can link (关联) something you need to remember with a place that you know very well. For example, to remember a list of numbers, imagine yourself walking through your house. Each thing is linked to a number. For example, zero could be the handle on the door and five could be the painting on the wall.

    In one study, some ordinary people were given 20 minutes to remember 72 nouns. At the beginning, they could only remember 26 words, but when they were taught loci, they could remember 62 words.

    "Not everyone can become a memory winner. But everyone using the technique can improve his memory greatly," said Boris Konrad, one of the researchers in the study.
