Red Ribbon Week is held every year, usually during the last week of October. It started with a police officer named “Kiki” Camarena. He was sent to Mexico in order to investigate(调查) a Mexican drug company and stayed there for four and a half years. His efforts helped put a stop to several major drug making companies. So the bosses wanted to murder the men who brought them down. When Camarena left his office for a lunch date with his wife on February 7, 1985, a car drove up and kidnapped(绑架) him, and a month later he was killed. At that time he was only 37 years old.
Shortly after his death, people in Camarena's town began wearing red ribbons in his honor. Then Camarena's high school friend, Henry Lozano, started Camarena Club. Hundreds of people joined the club and promised to be drug-free in order to honor the death of Camarena. And then schools in several states began to join in. Now, at the end of every October, millions of Americans wear red ribbons in memory of “Kiki” Camarena. So, in 1988, the first national Red Ribbon Week was founded in America.
Red Ribbon Week has become the largest drug education and prevention organization in the United States. It encourages communities to stand up against drugs and it encourages children to make a promise not to take drugs in their life.

    When my friend first arrived in Australia, he saw an old man selling some cheap goods(商品) in the street of Sydney. The old man was one of the poor people in Sydney and in fact there was no difference between them and beggars(乞丐). Most of them were some lonely old people. My friend was a kind hearted man, so he quickly gave some money to him. The old man asked him to pick some goods from him. My friend had no interest in those goods, so he left without choosing. But the old man followed him all the way.

    At first, my friend didn't think a lot, just thinking he would go home. But then when he went very far and saw the old man still following him, he was a little angry, thinking the old man must feel he was kind and wanted more money. My friend turned back and told him with sign language(手语) not to follow him because he didn't have much money.

    But the old man seemed not to understand, speaking something unknown and still following him. My friend happened to meet his Australian friend in the street. Hearing his story, his friend turned to ask why the old man was following his friend. The old man was out of breath, "My son, you gave me money, but you didn't want my things, so I have to give you something. I see you are a foreigner, likely not familiar(熟悉) with our city. I just want to follow you and show you the way. All I can do for you is this..."My friend was surprised. He said he didn't know why, but he felt the old man was just like his father, nice and warm.

    Some people seem 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.
