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. |

One very cold day，a snowstorm blew into our area. Needing firewood，I quickly set out with my best friend，Bruce，to look for a tree to cut down. I was glad to have Bruce along with. Cutting down a tree in a snowstorm can be dangerous. So it was important to have a friend who could warn me of danger.
When I chose a big tree about 23 meters tall and prepared to cut it down，my best friend suddenly warned me，“Don’t cut down that tree！It’s too close to the power line！﹙电线﹚”I wasn’t sure about it. So I decided to disregard his warning. I wanted to finish the job quickly and go home. So I began cutting down the tree. When the tree fell，there was no longer any doubt that my friend was right.
The tree caught the power line，bringing it to the ground. I considered cutting the tree off the line. After all，electricity can’t travel through wood，so I could safely remove the tree. As I reached out my finger to touch the tree，pain ran up my arm and through my head. I was shocked!
After I returned home and told my mother what had happened，she quickly called the power company. The workers from the power company soon arrived on the scene. One of them asked if I had touched the tree，and when I told him I had，his face turned pale.
“You should have been killed，” he said.
So why am I still alive？It was my boots that saved my life.
Within two hours，the workers removed the tree. Soon the snowstorm calmed down—but not my mother.
Even though she was glad I wasn’t hurt，my mother was still serious. After all，I shouldn’t have brushed off my friend’s warning.
Through this experience，I learn it’s important to listen to people who offer a different perspective. Taking time to listen might actually save a lot of time and trouble. It certainly would have kept me from getting the “shock” of my life.
