Many cultures have different ideas about why people catch colds. For example in the United States, some people think that you can catch a cold if your feet get cold. So, mothers tell small children to wear warm boots in the winter. In other places, including parts of the Middle East, some people believe that strong winds cause colds. So, on trains and buses, people usually don't like to sit next to open windows. In parts of Europe, some people think that wearing wet clothes will give you a cold. They say that after you go swimming, you should quickly put on dry clothes. Today, scientists know that colds are caused by a virus（病毒）. But the old ideas are still very strong, and many people still follow them to avoid（避免）getting ill.

    People use their mouths for many things. They eat, talk, shout and sing. They smile and they kiss. In the English language, there are many expressions using the word “mouth.”

    For example, if you say bad things about a person, the person might protest and say “Do not bad mouth me.” Sometimes, people say something to a friend or family member that they later regret because it hurts that person's feelings. Or they tell the person something they were not supposed to tell. The speaker might say: “I really put my foot in my mouth this time.” If this should happen, the speaker might fee l down in the mouth. In other words, he might feel sad for saying the wrong thing.

    Another situation is when someone falsely claims another person said something. The other person might protest: “I did not say that. Do not put words in my mouth.”

    Some people have lots of money because they were born into a very rich family. There is an expression for this, too. You might say such a person, “was born with a silver spoon in his mouth.”

    This rich person is the opposite of a person who lives from hand to mouth. This person is very poor and only has enough money for the most important things in life, like food.

    Parents might sometimes withhold sweet food from a child as a form of punishment for saying bad things. For example, if a child says things she should not say to her parents, she might be described as a mouthy child. The parents might even tell the child to stop mouthing off.

    But enough of all this talk. I have been running my mouth long enough.

     About twenty years ago，Gao Xiaosong wrote the lyrics(歌词)of the classic folk song My old Classmate that touched millions of hearts．Now，as the producer of the new youth film of the same title，he is trying to do it again．

Starring Zhou Dongyu，22，and Lin Gengxin，26，My Old Classmate follows the pair's life and love from middle school，when they are tablemates(同桌)，through high school， college and beyond their graduation．

    In the first half hour，audiences(观众)constantly see the symbolic items(标志性物品)of the early 1990s,including pencil boxes and comic books．

The film also mentions important events that took place during the period from 1993 to 2013，including China's entry into the World'Frade Organization，the terrorist attacks against the US on Sept.11，2001，and the 2002 SARS outbreak in China．This attention to detail brings back many memories, especially among those who were born in the 1980s．

Then there's the main focus：the first love between Zhou's and Lin's characters．The film doesn't have a fairy tale(童话)ending，but director Guo Fan's way of storytelling is quite impressive．If audiences can see a little bit of themselves in the film，it has fulfilled its goal．And those who are experiencing their sweet first love need not worry too much，because no matter how it ends，the precious memories of it will always stay．

    Valentine's Day（情人节） is on February 14th every year. On this day, people send valentines to their loved ones. Valentine's Day is a special time to tell how much you care about（在乎） a person.

    Many people send candy in hearted shaped（心形的） boxes to people they love. Flowers are also presents that people send on Valentine's Day. Valentine cards with words are often used（被使用） by many people.

    Can you guess who gets the greatest number of Valentine cards in the USA each year? Is It mother or father, sister or brother? Is it uncle or aunt? Is it the special friend? No, it isn't!

    Mothers get a lot of cards, but school teachers get the most each year. Do you know who sends the most? Children do. Children send five times（倍） as many on February 14th as adults do.
