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(季節(jié)性抑郁癥)．

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 “l(fā)ittle sun” that gives off light to make people think the sun is shining and feel better.

根據(jù)短文內(nèi)容填空，每空填一詞。

We live on the earth. We use the sea around us. What do we take from the ocean? And what do we give to it?
We take fishes from the ocean—millions of kilograms of fish, every year, to feed millions of people. 【小題1】  We take minerals(礦物) from the ocean. We can get salt by evaporating(蒸發(fā)) seawater. 【小題2】   Many other minerals, such as gold, can be also got from the sea, but not by simple evaporation.【小題3】   Seaweed(海草) becomes food of many kinds— even candy, and ice cream—as well as medicine. Believe it or not, fresh water is another gift from the sea. We can’t drink ocean water.   【小題4】  But ocean water becomes fresh water when the salts are removed. In the future, we will find ourselves depending more and more on fresh water from the sea.
The sea gives us food, fertilizer, minerals, water and other gifts. What do we give the sea? We pollute the ocean all the time. 　【小題5】　Throwing waste into the ocean is killing off sea life. Yet as the world population grows, we may need the sea and its gifts more than ever.
We are finally learning that if we destroy our sea, we might also destroy ourselves. Hopefully, it is not too late.
