In winter，when the sun hides behind the clouds，everyone feels a bit low. You may be tired and find you want to sleep all the time. What you may not know is：you are suffering from (患有) SAD(季节性抑郁症)．

But don't worry—it's normal. Colder temperatures and fewer hours of daylight can steal your energy and put you in a bad mood.

Read on to find out what SAD is and what you can do to help yourself or those around you.

These days，Linda，a US teenager spends most of her holidays sleeping instead of doing sports outside. She has also had trouble concentrating(集中精力) on her homework. When her mother asks her what's wrong，Linda doesn't know what to tell her. Linda may not realize it yet，but she's suffering from SAD. It causes people to sleep，eat sweet food and get sad or angry for no reason.

About 15 percent of American people now suffer from SAD in winter according to the US Department of Health. The US government has taken measures to help people beat it. Local communities encourage people to take part in activities such as exercise，dance or art. And they advise people not to eat too much sweet food.

Like in the US，cold northern European countries such as Finland，Iceland and Russia see a large number of people suffer from SAD every year. So，the sunlamp is widely used in these countries. It's an electric lamp which is just like a “little sun” that gives off light to make people think the sun is shining and feel better.

On June 26, 2000, two scientists, called Francis Collins and Craig Venter, told the world that they could read the whole “map” of the human body: DNA. DNA is something that everybody has, and it tells the body what to do. DNA is the reason that we look like our mother and father, because we get some of their DNA to make our own.

People have been trying to understand the human body for a long time. In 1860, Gregor Mendel discovered a special reason why we look the same as other people in our family. It is because of small things named “genes” in our body. In 1953, James Watson and Francis Crick made another discovery and found out that those small parts are real messages written in the DNA with a special language.

In 1961, Marshall Nirenberg and Johann Matthaci found a message in DNA showing how DNA tells the cell（细胞）to build its parts. Scientists have now found all the words in the DNA map, but we still do not understand what they all do. By understanding what just one “word”   means, we can help save more people from several illnesses.

Most people hope that this will help make better medicine and help sick people. Other people worry that when people begin to know more words and find out lots of other information, we might use it in a wrong way, just to make people more attractive, or stop sick people from getting jobs. Man would have to meet a lot of trouble if DNA technic wasn’t limited（限制）in use.

A principal decided to honor the teachers in his school to show his appreciation(感激)for their hard work. He told them how they made a difference in their jobs. Then he gave each of them a blue ribbon(缎带)that read, “Who I Am Makes a Difference.”
One of the teachers wanted to take this idea into her students. One day the teacher noticed that a boy in her class was unhappy. She went to him and asked him the reason. The boy told her that his father had been worrying about the job and often punished him for some little things. Hearing what he said, the teacher decided to give him the ribbon to cheer him up. She said, “Dear boy, what your father has done doesn’t mean the lack(缺少)of love for you. He needs your understanding. You’ve been a kind boy. Here’s a ribbon for you. Would you like to take this ribbon and pass it on? Let’s keep this ceremony going and find out how it affects people.”
That night the boy sat beside his father and said, “Dad, today my teacher gave me a blue ribbon for being kind and asked me to find somebody else to honor. I’d like to give the ribbon to you. I want to let you know how deeply I admire you and how much you mean to me. I love you!”
