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.

There are lots of dangerous and terrible insects in Northeastern India, but the tree-bees are the most terrible. They are killers. Unlike most bees which will sting (叮咬) you only if they are disturbed (打扰), tree-bees will attack you in thousands for no reason. And they will chase (追赶) you for your life.

Walking along a dusty road while I was on holiday there last year. I found myself, without the least warning, the centre of such an attack. The air above me suddenly became thick with bees. Though it was hot, I went cold all over. Until then I had never heard of Indian tree-bees, but I had recently seen a film called “The Angry Swarm”, which was about killer-bees.

I began running to the village about half a mile away, but I was soon covered from head to foot with bees. I drove them away with my hands, only to make room for others. Each time I opened my mouth for breath, more bees entered my mouth, until it was stung to twice its usual size and I could hardly breathe.

When I reached the village, I found some workers building a house. I ran towards them for help. But as soon as the workers saw the bees with me, they ran for safety at top speed.

Soon my eyes had completely closed. I fell into a pile of brick dust. I pushed myself wildly down into it until my head and shoulders were covered. And then I tried hard to get out of the dust, the angry bees made a new attack on me. I was tired out and ran weakly about in circles. Soon I lost my consciousness (意识).

Later I learned that two quick-minded villagers ran to a pile of dry grass and quickly surrounded (包围) me with a thick wall of fire and smoke until the bees were driven away. They stayed with me, taking stings out of my body for the next three hours until a doctor came and gave me further treatment.

A.e-a-c-b-d B.d-e-a-c-b C.e-b-a-d-c D.d-e-a-b-c
