Mobile phones help us easily find people anywhere at any time. A mobile phone can include many things, such as games, music and Internet access(互联网接入). Today, 4.6 billion people around the world have mobile phones, according to CBS News.

However, mobile phones may cause cancer, according to the World Health Organization. In a 2010 study, people who used a mobile phone for 10 years or more were more than two times as likely to get brain cancer, according to CNN.

“I think it is a good idea to give the public some kind of warning that long-term exposure(暴露) to radiation (辐射) from your mobile phone could possibly cause cancer,”told Dr Henry Lai. Lai is a scientist of bioengineering(生物工程) at the University(大学) of Washington who has studied radiation for more than 30 years.

These suggestions may help you reduce your risk of cancer:

1. Use a headset(耳机) or speaker

Headsets give out much less radiation than phones. Some headsets give out low-level radiation. However, you should take it off your ear when you’re not talking to anyone. Using your phone with a speaker will also make it safer.

2. Listen more, talk less

Your phone gives out radiation when you talk or text, but not when you’re listening or getting messages. Listening more and talking less can lower the risk of cancer.

3. Hold the phone away from your body

Hold the phone away from your body when you’re talking, not against your ear. Also, don’t keep it in your pocket.

4. Choose texting over talking

Phones give out less radiation to send texts than to carry a person’s voice. Texting also keeps radiation away from your head.

5. Poor signal? Stay off the phone

A poor signal means that the phone needs to give out more radiation to work. Make and take calls when your phone has a strong signal.

“Volunteering makes you look at the world differently. You see how little things can change a person’s life for the better, which makes everyone a better person.” Mason, a volunteer said.

National Volunteer Week started in 1974 and is held every April. It is a time to thank volunteers for their achievements. It is also a perfect opportunity(机会)to encourage others to take their first step toward becoming a volunteer. Making the decision to take the first step can be the biggest problem, because they often wonder if they will be able to meet the organization’s expectations. Some people fear not knowing anyone else in the group. Not having enough time also prevents some from sharing their abilities.

The following tips can help if you have some of these worries.

★Start out slowly, don’t add too much pressure. Even a few hours a month can make a big difference in someone’s life.

★Choose an organization with the same interests and common values.

★Take part in a training meeting for new volunteers, even if it is not asked.

★Work with a veteran volunteer. He volunteered a lot and he can help you increase the confidence and completely understand the organization’s expectations.

★Invite a friend or family member to serve. It is a good experience to volunteer with them.

★Finally, it is most important to enjoy the volunteer experience and to remember that not all volunteer experiences are perfect. If one experience doesn’t work, don’t give up and you’ll surely find the right opportunity.

Spend some time on volunteer work and you will see great changes in people’s lives. As Mason discovered during his volunteer experience, “…little things can change a person’s life.”
