    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.

    A cold is the most common illness among us.这里有一些建议来防止感冒。

    Drink lots of hot water. This is an effective way to stop a cold. You'd better take at least 8 to 10 glasses a day.

    Check your temperature often. If your temperature is lower than 102 degrees F, don't care much about it. With your body temperature being higher than normal, it will be difficult for the viruses (病毒)to grow. In other words, having a low-grade fever (up to 102°F) is your body's way to protect itself from viruses.

    Make your sore throat feel better. Chicken soup or any kind of sour soup you like, is an excellent choice.

    Gel enough rest and slay warm. You should get enough sleep. Make sure to keep yourself warm and dry because you may feel cold at that time. If you are starting to sweat a lot, change your clothes immediately. You do not allow your sweat to just dry especially on your chest and back. As much as possible, wear cotton-made clothes to allow your skin to breathe and make you feel more comfortable.
