Winter is often bitterly cold, which often makes us stay indoors more instead of heading out to exercise. Worse still, there are many viruses doing their best to make you sick. And sneezing, coughing and nose blowing make the rooms a habitat for viruses. 1.. Touching a doorknob or shaking a hand may make you get sick. Although it may sound terrible, there are still some things you can do to avoid viruses. Here are several simple tips to stay healthy in winters.
Wash your hands
You pick up viruses everywhere and they live on your hands, so wash your hands and do it often. 2. But if that’s not available, use an alcohol-based hand sanitizer (消毒杀菌剂).
3.. Avoid touching your eyes, nose and mouth with your hands. That’s one way viruses can get into your body.
Get the flu shot (疫苗)
4., but getting the flu shot lowers your chances of getting the flu. For example, getting the flu shot last year resulted in a 34% lower risk of coming down with the flu.
Avoid sick people
5.. Viruses spread very easily through the air, so keep at least six feet between you and the sneezing, sniffling and coughing person.
A. It’s no guarantee
B. Take care of your face
C. Keep your hands away from your face
D. The best way is to use regular soap and water
E. It is easy for viruses to spread from person to person
F. If someone around you is sick, then keep your distance
G. Because there are always some unexpected things in life
A scientist locked himself in a small air-tight plastic tent with 200 plants to see if they could change CO2 into oxygen (氧气) fast enough to keep him alive.
Kurtis Baute locked himself in a 3m by 3m tent in his brother’s backyard in British Columbia, Canada. He hoped to find out if by surrounding himself with plants, the CO2 he breathed out could be changed into oxygen to allow him to survive in the locked tent for at least three days. Unfortunately, he had to give up the experiment after only 15 hours, as CO2 levels reached a dangerous point where he risked suffering brain damage.
“I could probably survive in the tent for three days,” Baute wrote on his website. “But my goal is not to just ‘not die’. My goal is to end this project without developing brain damage or just generally causing lasting harm to my body. But as it turns out, that’s exactly what he risked as the 200 plants he took with him into the tent couldn’t meet his needs. Clearly, a cloudy sky prevented them from receiving all the sunlight they needed to perform photosynthesis (光合作用), so they couldn’t recycle CO2 fast enough.
“Plants are great at taking in CO2 and they love it. Since it wasn’t a bright and sunny day, they weren’t getting the light they needed, which meant CO2 just kept rising. I had to give up the experiment as that continued.” the young experimenter said.
15 hours into the experiment, Baute reached the set danger point and then ended this experiment. Still, he called the experiment a “huge success” as his main goal was actually the terrible effects of climate change and CO2 emissions. “The conclusion about my experiment is that if CO2 is too high, I’ll escape, which is just everyday experiences for many people on this planet. Everyone deserves clean air, but not everyone has it,” he wrote.

B. Surviving in the tent
C. The set danger point
D. Making people know the use of plants
After a five-year pause, the Billboard Music Awards officially returned to the United States. Two of the big winners at this year’s awards were Rihanna and Taylor Swift. But a major symbol of the show’s popularity came from others such as Beyonce, U2, the Black Eyed Peas, and First Lady Michelle Obama.
This year marks the Billboard Awards’ rebirth. The Billboard Awards had been a big event since 1989, but the award in 2006 seemed to be its last award.
This year the show was brought back in Las Vegas, broadcast live on ABC, and hosted by “The Hangover 2” star Ken Jeong. However, like many other awards shows, the three-hour awarding ceremony served more as a marketing tool for today’s pop stars than an award presentation.
The show was packed with fans. Cee-Lo Green floated in the air with his piano. Surprising duets (二重唱) between Rihanna and Britney Spears, and this year’s Billboard Icon Award winner, Neil Diamond made the fans sing along to “Sweet Caroline” and “America”.
Rihanna’s two wins were Radio Artist of the Year and Top Female Artist. Taylor Swift won the evening’s first award, as Top Album Artist, as well as Top Country Artist
Beyonce received a special “Millennium” Award for her career achievements: The 29-year-old star was praised in a video by a series of other stars, including Lady Gaga and Michelle Obama. She also performed her new song, “Run the World”.
The Billboard Music Awards are given to the most popular artists in the mainstream music scene. The finalists and winners are determined by their rank on the Billboard charts.

Adidas and Puma have been two of the biggest names in sports shoe production for over half a century.
Since 1928, they have supplied shoes for Olympic athletes, World Cup football heroes, Muhammad Ali, hip hop stars and rock musicians famous all over the world. But the story of these two companies begins in one house in the town of Herzogenaurach, Germany.
Adolph and Rudolph Dassler were the sons of a shoemaker. They loved sport hut complained that they could never find comfortable shoes to play in. So they started making their own. In 1920, Adolph made the first pair of athletics shoes with spikes (钉状物), produced on the Dasslers’s kitchen table.
On 1st July 1924, they formed a shoe company, Dassler Brothers Ltd and they worked together for many years. The company became successful, but in 1948, the brothers argued. No one knows exactly what happened. The result was that Adolph left the company. His nickname was Adi, and using this and the first three letters of the family name, Dassler, he founded Adidas. Rudolph also founded and relocated his own company across the River Aurach. At first he wanted to call it Ruda, but finally he called it Puma.
After the big split of 1948, Adolph and Rudolph never spoke to each other again and their companies have now been in competition for over sixty years. Both companies were for many years the market leaders, though Adidas has always been more successful than Puma. A hip hop group, Run DMC, has even written a song called My Adidas and in 2005 Adidas bought Reebok, another big sports shoe company.
The terrible family argument should really be forgotten. Ever since it happened, over sixty years ago, the town has been divided into two. Even now, some Adidas employees and Puma employees don’t talk to each other.

C. 16 years. D. 60 years.

A. separation B. connection
C. cooperation D. celebration
4.What can we learn from the text?
