Just hearing the name of the great white shark makes people afraid. In fact， they have more to fear from us than we do from them. For many years， lots of great white sharks were killed.
But thanks to people’s efforts， the population of these sharks is rising again in the US， according to two recent studies.
Why is their growing population something to celebrate? Great white sharks play an important role in the ocean ecosystem. As the biggest predators， they help keep the population of other creatures from growing too large. If the population of an species(物种) gets too big， it will affect the food chain.
Although they are very important， great white sharks had been hunted for their meat and fins for a long time. In 1997， a law was passed in the US to stop the hunting of great white sharks. Gradually， the numbers of sharks started to increase.
The law wasn’t the only thing that has helped great white sharks. Environmental protection groups have also played a part. The research group， OCEARCH， puts an electronic device(装置) on a shark’s fin and then tracks(追踪) its movements. Just as important， they let the public follow each shark as it travels the world’s oceans. OCEARCH also gives each shark a name. The group’s most famous shark is a shark named Katharine. Thousands of people have tracked Katharine’s movements on the website. This helps people see sharks in a new way --- not just as the dangerous killers seen in movies. Learning about sharks makes people want to do more to protect them.

When you cough or sneeze, please turn your head away from others and cover your mouth with the full part of your hand. Afterwards, you should say,” Excuse me.” This is a rule I set for my students
It is so simple, but many kinds have never been told to do this. In fact, I notice adults cough and sneeze in public without putting a hand over the mouth. I hate traveling by subway(地铁) in New York during cold and flu season, because it is certain that someone is going to stand right behind me and cough or sneeze on my neck.
One important thing I point out to the kids is that after they sneeze or cough on their hand, they should wash their hands as soon as possible. Otherwise, they will be passing those germs(病菌) along to everything and everyone they touch.
In order to help the kids remember this rule, I tell them about an old story. It says that when you sneeze, evil spirits jump into your body. If you don’t cover your mouth, the spirits will enter, but if you cover your mouth, you will keep them out, We say “God bless you” when someone sneezes, and in Germany you should say “Gesundheit”. That means “Good health to you. “ Both expressions are said just in case you didn’t cover your mouth in time and the spirits were able to enter your body. The kids love finding out the origins(起源) of these expressions and it encourage them to put the advice to use more often.The writer of this article must be _______ .

After our hospital visit, my husband and I needed cheering up, so we thought we would treat ourselves to a big breakfast at our favourite restaurant. While we were waiting for our meals, we decided to use all our small change and make our wallets light, so we counted it out as we waited.
I vaguely(含糊地) remember seeing a man sitting nearby. When our meals arrived, we found a note. It read,” Your breakfast has been paid for. Hope you have a lovely day.”
It was a wonderful surprise as nothing like that had ever happened to us. He must have thought we could hardly pay the bill. We looked around to thank him, but he had left.

Chinese people call the Spring Festival“Nian”. But do you know that Nian
was once the name of a monster(妖怪)?
A long time ago, the monster Nian lived in the mountains. It ate
animals. But in winter, it could not find food. So it came to villages and
ate a lot of people. People were so afraid of Nian that they locked their
doors before evening came during the winter. One day, an old man came to a
village. He told people there that Nian was afraid of three things——the
color red, fire and noise. He told people to play drums and gongs, make
big fires and set off fireworks(放鞭炮)to make Nian go away.
On a moonless, cold night, Nian went to the village again. As soon as it
opened its big mouth, people made loud noises and made fires. Nian was
really afraid and ran away. wherever it went, there was noise and fire.
When Nian was tired and could not run anymore, people killed the monster.
After that, on the coldest day of winter, people beat drums and gongs,
and set off fireworks to celebrate the death of the monster of Nian. They
put up red lanterns and have a big dinner without sleeping during the
night.
In the morning people greet each other happily. So now we have the
Spring Festival. From the story, Nian seemed to be long, long ago.
