    Language students often think they have memory problems. They worry because they can't remember words. In fact, the problem usually isn't with their memory. The problem is with how they study.

    To remember words better, you need to understand how memory works. There are two kinds of memories: short-term and long-term. When you see, hear, or read something, it goes first into short-term memory. But short-term memory lasts for only a few seconds. You will only remember something longer if it goes into long-term memory. Your long-term memory is like a very big library with many, many books. And like a library, it's organized (有条理的). When you put away a book – or memory – you can't just leave it anywhere. You have to choose a place where you can find it again.

    How can you do this with vocabulary? The answer is to work with the word and think about the word in new ways. You can do this by writing new sentences that include it. Even better, you can invent a little story about the word, with people or places that you know. Another way is to make a picture in your mind with the word. For example, if the word is height, you can think of the tallest person you know and try to guess his or her height. All of these activities are good ways to think about words. They make the meaning of words stronger in your long-term memory. And they give a way to find a word when you need it.

    Three years ago, I got to know a poor lady named Rose. She had no children and lived alone. When I went to visit her, I always took her some1and food. One day she asked me to have coffee and delicious food for lunch at a restaurant near her home.

    2the way, I began to worry: I knew that she had no money, but if I offered to3the lunch, I was afraid I must hurt her.

    There were many people in the4and all of them were happy. Rose told me to sit and drink coffee by the window. Then she went into the5. I didn't know what happened. After about 20 minutes, she came out with some food. Then we started to enjoy the delicious food together. She told me that the restaurant allowed people to work for a meal6they had no money. The restaurant also might give them a free meal if they were not7to work, especially for the disabled.

    I 8remember the beautiful afternoon I shared with Rose. We had a meal, and Rose paid for it by her work. The weather was9and bright, and everyone's smile was warm and bright as well.

    I'm still thinking that life cannot be easy to us, but we can still do something for our friends and other people. The world will be10if everybody would like to share happiness with others.
