　　CELL phones help us easily find people anywhere at any time．A cell phone can include many things, such as games, music and Internet access．Today, 4.6 billion people around the world have cell phones, according to CBS News．

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

　　The following suggestions may help you reduce your risk of cancer：

　　1．Use a headset(头带式耳机)or speaker

　　Headsets give out much less radiation(辐射)than phones．Some wireless(无线的)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 emit(发出)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

　　Fewer signal bars on your phone mean that the phone needs to give out more radiation to work．Make and take calls when your phone has a strong signal．

　　It comes without warning．It destroys people’s bodies．It kills almost 5,000 people around the world every day．This is AIDS – one of the most dangerous human diseases on the Earth．

　　December 1 is World AIDS Day．This year’s theme is “Getting to Zero：zero new HIV infections(传染), zero discrimination(歧视)and zero AIDS – related deaths”．

　　AIDS stands for Acquired Immunodeficiency Syndrome(获得性免疫缺陷综合症)．It is caused by HIV – a virus(病毒)．HIV travels in people’s blood and affects T cells(细胞), a type of cell that helps the body fight diseases．It may take years for the virus to harm enough T cells for the infected person to get sick and develop AIDS．

　　HIV and AIDS spreads through blood-to-blood contact, sharing needles or having blood transfusions．A mother with HIV can give the virus to her unborn baby．Unsafe sex can also spread AIDS．

　　Right now there is no cure(治疗)for HIV or AIDS．However, new treatments can help people with the virus live longer．The “AIDS Cocktail(鸡尾酒疗法)”, uses several drugs mixed together like a cocktail．It can help people with HIV to live longer．

　　On World AIDS Day, people wear red ribbons to show they care about HIV and AIDS．American artists thought up the red ribbons in 1991．They chose red because it is bold and visible – symbolizing(象征)passion, a heart and love．

　　How much do you know about AIDS?

　　Q：Can you get AIDS from shaking hands with someone who has AIDS?

　　A：No．The HIV virus cannot live outside the human body．So social contact such as hugging(拥抱)or kissing an AIDS patient cannot give you AIDS, either．

　　Q：Can you get AIDS if mosquitoes(蚊子)bite(叮咬)you?

　　A：No．Mosquitoes do take blood from people but they do not exchange blood between people．

　　Q：If a dog bites someone with AIDS, and then bites you, can you catch AIDS?

　　A：No．AIDS only affects humans．Animals cannot catch this illness from people, and people cannot catch it from animals．
