Below is some advice on how to prevent colds and flu.

8 Ways to Avoid Colds and Flu

1. Wash your hands and wash them often

The US Naval Health Research Center conducted a study of 40,000 volunteers who were ordered to wash their hands five times a day. The volunteers cut their incidence of flu by 45 percent.

2. Wash your hands twice every time you wash them

Researchers at Columbia University found one hand washing had little effect, even when using antibacterial soap. So wash twice if you’re serious about preventing colds.

3. Change your toothbrush every three months

You think your toothbrush gets your teeth clean — and it does. But once you’ve finished brushing, it can be a breeding ground for germs. Most dentists recommend you change your brush every two or three months. It’s also a good idea to replace it after you’ve had a cold or flu.

4. Sneeze and cough into your arm or tissue (纸巾)

Whoever taught us to cover our mouths when we cough or sneeze got it wrong. That just puts the germs right on our hands, where you can spread them to objects — and other people. Instead, put your arm over your mouth and nose when you sneeze or cough if a tissue isn’t handy. It’s pretty rare that you shake someone’s arm, after all.

5. Stop blaming yourself when things go wrong

Believe it or not, blaming yourself makes you more likely to catch a cold! Researchers found that even those who had control over their work were more likely to begin sneezing if they lacked confidence or tended to blame themselves when things went wrong. Such attitudes make people more stressed on the job, and stress, as you know, can challenge your immune system.

6. Once a day, sit in a quiet, dim room, close your eyes, and focus on one word

Meditate (冥想). It is a proven way to reduce stress. Studies have shown that stress weakens your immune system. In fact, people with high stress levels have up to twice the number of colds as non-stressed people.

7. Get moving

Ride a bike, join a dance class, or go for a walk. A study found that older women who did 45 minutes of gentle exercise, five times a week for a year, were up to three times less likely to get a cold than women who took little exercise. The researchers found that the exercisers’ immune system was strongest in the last three months of the study.

8. Leave the windows in your house open a crack

You don’t have to keep all of them open, but one or two in the rooms in which you spend the most time. This is particularly important if you live in a newer home, where fresh circulating air has been the victim of energy efficiency. A bit of fresh air will do wonders for chasing out germs.

 

1.To prevent yourself from getting colds, you should wash your hands____.

  A. twice every hour                                        B. twice every time

  C. five times every hour                                  D. five times every time

2.When you cough or sneeze, you should ____.

A. put your hands over your mouth

B. avoid shaking hands with other people

C. cover your mouth with your arm or a tissue

D. keep away from other people

3.Your immune system will be weakened if ____.

  A. your stress level is high

  B. your room is not bright

C. you have control over your work

  D. you do not exercise for 45 minutes every day

4.If you live in a new house, it is particularly important to ____.

  A. leave all the windows open a crack

  B. leave only one or two windows open to save energy

  C. keep one or two windows open in the rooms where you spend the most time

  D. keep all the doors and windows open to let in more fresh air when you are at home

Some people would go through anything just to achieve their dream. Kasia Siwosz is proof. For the final year student on the university women’s tennis team, the road to Berkeley, University of California was met with poor advice and misinformation from her home country and two unsuccessful stops along the way that fell short of expectations.

    Born in Poland, Siwosz began playing tennis at seven years old and developed the skills that helped her earn a top-50 ranking among the ITF Junior division (国际网球联会青少年赛).. Siwosz wanted to do more with her life than just play tennis, which led her to seek chances that would also allow her to obtain a top education. While most who grow up in the U.S. are naturally accustomed to the American tradition of collegiate (大学的) sports, such a custom is not as familiar in a country like Poland. “There’s no collegiate sports in Poland and no culture of sports and academic (学术的) study there. You can only do one, not both,” Siwosz said.

    Her desire to have a quality education led her to America to follow her dream. While Siwosz was talented enough to begin her collegiate tennis career, she could only attend community college because she missed the deadline to apply to four-year schools, mainly due to misinformation provided in her home country of Poland.

    When she had earned all her credits and was able to transfer (转学), Siwosz made the decision to attend Baylor in Texas. Her friends from Poland put in a good word for the university, saying that it was a good fit because there were many international players at Baylor. “I thought it would be a good idea, but it really wasn’t what I thought it would be,” Siwosz said. “I wasn’t happy at Baylor. The level of tennis was high, but the academic standards were no match and I just wanted more.”

    After one year at Baylor, Siwosz’s luck finally began to change when she made the decision to transfer to Berkeley, which was due in large part to Lee, a former Berkeley student. Lee, who is a keen tennis player himself, met Siwosz four years ago in Texas. “I knew she was unhappy there,” he said. “I saw the opportunity for her to come here.” Siwosz visited Lee in Berkeley. “I ended up loving this place and this school,” Siwosz said. “I came here a lot over the summer, I gave it a shot and I ended up with a Berkeley education and a spot on one of the best college tennis teams in the country.”
