Since last year, the heavily smog has occurred in our city. The smog, that has made our daily life inconvenient, has also done great harm people's health. Many traffic accident have happened because of the bad weather. Besides, many people have to stay inside to avoid the harm air. What's the worse, many people have suffered from bad coughs, sore throats but other serious diseases.
Personally, I thought we should make efforts to protect the environment. I strongly agree with the idea what we can try to drive less and buy green products. Only when we have the awareness（意识）of environmental protection can us have cleaner air.

Can a bowl of chicken soup help fight a cold? Maybe. But will going outside with wet hair make you sick? No. 1. Here are some more.
Feed a cold, starve a fever. Being sick often makes you eat less. But force-feeding won't help. What will help is drinking more water and getting enough calories. A 2008 study found that mice having flu took longer to recover and were more likely to suffer ill effects if they were dieting. 2.
Vicks VapoRub(薄荷膏) in your socks treats coughs. A widely spread post on line once suggested putting Vicks VapoRub on feet at night and covering them with socks to treat coughs. 3.VapoRub is usually used on a child's chest or throat to reduce cough. So it would not work in your socks. Still, some fans stand by this treatment.
4. Colds and flu are caused by viruses. They do spread during cold-weather seasons, but you're more likely to pick them up inside than out. In fact, going outside and getting more physical activities-and not just during cold and flu season-may help prevent sickness.
A wet head can make you sick. You'll probably feel cold if you don't blow your hair dry on a cold day, but not much else will happen. 5. Unless you are so cold that you get a low temperature, which could make you sensitive to flu, wet hair or clothes won't increase your possibility of catching a cold.
A.It became an internet popularity.
B.You'll get sick if going out without a coat.
C.Again, colds are caused by a virus.
D.That's just an incorrect traditional belief in cold.
E.But you have to actually wear it for the health benefits.
F.Experts suggest adding medicines three times a day to your meal.
G.The researchers' suggestion is to stop dieting until after flu season.
Earlier research had suggested we're best at learning grammar in early childhood. Then we hit a dead end around age 5. It's supposed to be much harder for older kids. The time when people can learn the rules and structure of a language well appears to last until around age 17 or 18. “But that's not so, ”says psychologist（心理学家）Joshua Hartshorne.
Hartshorne asked friends to take an online English grammar test. After completing the test, volunteers answered questions about where they had lived, the languages they had spoken from birth and the age at which they first started learning English. Hartshorne also asked how long they had lived in an English-speaking country. As he had hoped, people shared the test widely online. This let Hartshorne's group study the answers from 669, 498 native and non-native speakers of English. The researchers used statistics to find out when people with different English-speaking experiences reached their top grammar ability.
If people moved to a new country and began speaking English by age 10 to 12, they finally spoke it as well as folks who had learned both English and another language from birth. But both groups scored a little worse than people who spoke English only, the researchers found. The test results showed that around age 17, people's ability to learn grammar took a sharp drop. And those who started learning English after age 10 or 12 never reached the same level of English skillfulness as people who started younger. Why？The researchers think it's because they had fewer years to practice before their skills dropped off at surprise：Language learning did not end at 17. People's English skills kept improving a little until around age 30, the new study found. And this was true among both native speakers and those who learned English as a second language. Still, most language learning happened by age 20, the new study decided.

Churchill, Manitoba is a small town. The northern winds roll through it from Canada's Hudson Bay. It might be just another point on the map if not for its seasonal settlers.
It happens like clockwork every fall that hundreds of polar bears make their way through the town to the freezing bay where they hunt for seals after the ice packs enough to support their weight. The animals have been connected with Churchill since at least 1619. That's when Norwegian explorer Jens Munk and his sailors recorded making a meal of one bear while they wintered in the area. “It was of good taste and did not disagree with us. ”That's what Munk wrote in his journal.
Over the years, the animals' coming has earned the town the name of“Polar Bear Capital of the World. ”Today, Churchill's bear population goes beyond its human population. There used to be about 7, 000 residents but now only 813 living there. There was no such thing as an organized tour group to see the bears until 1980. The town might have been in terrible financial hardships. But the growing bear tourism industry helped.
Today, some 10, 000 tourists come to the town to see polar bears for six weeks in autumn every year. But the reasons why they come are different from before. Everyone was happier and they had such a good time seeing polar bears. Now things have changed because the word is out that this Western Hudson Bay population of bears, Churchill Bears, are going to be the first population of polar bears to die out. So when the tourists come up, they all have a little bit of a lump in their throats（如鲠在喉）because they're looking at a beautiful bear, but they're also looking at a dying-out bear, which makes the whole attitude toward the bears different. Unfortunately, that's becoming the major part of the whole attraction of the tours as well. Come and see the bears before it's too late.
