Rich or poor， young or old， we all have problems. We should learn how to deal with our problems. Here are some ways.

    Firstly， we should learn to forget.有时我们会生朋友的气。Good friendships may be lost. Sometimes children have disagreements and decide not to talk to each other. However， this usually does not last for long. This is an important lesson for us: we can solve a problem by learning to forget.

    Secondly， we should regard problems as challenges(挑战). Many students often complain about school.他们有太多的作业要做。They think the rules are too strict. Education is an important part of our development. As young people， it is our duty to try our best to deal with each challenge with the help of our teachers. Don't worry about our problems. Let's face the challenges.

    If you ask people of different countries "Could you tell me the way to the post office?" you will get different answers.

    In Japan, people use landmarks（路标）instead of street names. For example, the Japanese will say to travelers, "Go straight down to the corner. {#blank#}1{#/blank#} The post office is across from the bus stop. "

    In Kansas, America, there are no towns or buildings within miles. So instead of landmarks, people will tell you directions and distance. For example, people will say, "Go north two miles. {#blank#}2{#/blank#} "

    People in Greece sometimes do not even try to give directions. They will often say, "Follow me." {#blank#}3{#/blank#}

    Sometimes if a person doesn't know the answer to your question, he or she might say, "Sorry, I have no idea." But in Yucatan, Mexico, no one answers "I don't know." {#blank#}4{#/blank#}They usually give an answer, but often a wrong one. A visitor can often get lost in Yucatan!

    {#blank#}5{#/blank#}You might not understand a person's words, but maybe you can understand his or her body language. He or she will usually point to the right direction. Go on in that direction and you may find the post office!

    One day, you open the fridge and find some moldy(发霉的) food. But before you can throw it away, your mother stops you. She doesn't want to waste food. She cuts off the moldy pan and eats the rest. Is it safe to do this?

    Mold(霉菌) can grow on almost all kinds of food. Mold is usually green, white, black or gray.

    Mold makes food ®oft and changes it's color. Moldy food tastes quite bad—and it's not safe to eat.

    If you find mold in soft food, just throw it away. Bread, tomatoes and hot dogs are soft food. This kind of food allows mold to easily grow below its surface.

    But it's easy to remove mold from hard food. The mold can't grow very deeply inside this kind of food. According to the BBC, you should cut about 2.5 cm around and below the mold and remove it.

    It's OK to cut the moldy parts out of hard food and eat the rest. But if the food is completely covered with mold, you should still throw it away.

    Most kinds of mold are bad for us. But some kinds of mold can be used to make food. For example, peniciliium(青霉菌) can be used to make many types of cheeses, such as blue cheese. These cheeses are safe to eat and they're quite delicious as well:

    "How are you?" is a nice question. It's a friendly way people in the United States greet each other. But "How are you?" is also a very unusual question that often doesn't have an answer.

    When a person meets a friend on the street and asks "How are you?", he only expects to hear the answer "Fine." even if the other person isn't! The reason is that "How are you?" isn't really a question and "Fine." isn't really an answer. They are simple ways of greeting people and saying "Hello".

    Sometimes, people also don't say directly what they mean. For example, when someone asks "Do you agree?", the other person might be thinking "No, I disagree." But it isn't very polite to answer so directly, so the other person might say. "I'm not so sure." It's a nicer way to say that you don't agree with someone.

    People also don't say directly what they are thinking when they finish conversations with others. For example, many conversations over the phone end when one person says, "I've got to go now." Often, the person who wants to hang u gives an excuse: "Someone's at the door." "Something is burning on the stove!" The excuse might be real, or it might not be. Perhaps the person who wants to hang up simply doesn't want to talk any more, but it isn't very polite to say that. The excuse is more polite, and it doesn't hurt the other person's feelings.

    Whether they are greeting each other, talking about an opinion， or ending a conversation, people often don't say directly what they are thinking. It's an important way that people try to be nice to each other, and it's all part of the game of language!
