问题     We’ve all seen the headlines about mobile phones. If you believed everything you read, you’d throw your mobile away immediately for fear of everything from cancer to infertility. And that’s before we even start to think about mobile phone base stations. 40 percent of people surveyed believed that masts are likely to cause health problems. So what’s the truth? Should we worry about our mobile phones?
    A vast amount of research has been done into mobile phone handsets. A few studies have claimed that some phones can cause higher rates of brain tumors.
【C1】______
    In 1999, the government commissioned an independent group of experts to look into the potential risks of phones. The result was the "Stewart Report", published in April 2000. This report advised that gaps in our current knowledge mean we should take a "precautionary approach" to phone use.
【C2】______
    In 2000, the Department of Health published a leaflet summarizing the recommendations from the "Stewart Report". This leaflet is supposed to be distributed by every mobile phone retailer. Sadly not all of the retailers are doing this.
【C3】______
    However, the dispute is still out on mobile phone handsets, especially the mobile phone base stations. Is there any clearer evidence that they cause health problems? Again there is conflicting information. The "Stewart Report" does not state implicitly any adverse health effects when exposed to a mobile phone. However, many people up and down the country are suspicious.
【C4】______
    The Should I Worry About team decided to carry out a test. They put ten students in a house for ten days and erected a mobile mast in the garden. They weren’t entirely honest with them though; they told the students the mast was on at the start of the experiment and off at the end. In fact it was off at the start and on at the end. What’s interesting is that the only time any of the students felt ill was when the mast was OFF but they thought it was ON.
【C5】______
    Then, should we all chuck our phones in the bin? Probably not. The benefits do seem to outweigh any possible dangers, and there are things you can do to protect yourself from any possible health effects. So if you are worried, use a hands-free kit. When your signal is very low, switch your phone off because it’s working extra hard at those times.
[A]But don’t throw your phone in the bin just yet. Results which suggest that mobiles might damage health are actually rare. Those that do tend to have been done with old style analogue phones, which use a much stronger signal than modern phones.
[B]The leaflet is available in every phone. Next time you buy a mobile phone, do not forget to ask for one.
[C]Given the immense numbers of mobile users, even small adverse effects on health could have major public health implications.
[D]For adults this means using our phones for limited amounts of time. For children the advice was much stronger. The report recommends that under-16s use their phones only for essential calls.
[E]The International Agency for Research on Cancer found a link between childhood cancer and mobile phones. Like power lines, mobile phones also emit radiation.
[F]The small experiment suggests that people’s fear of phone masts can be a factor in making them feel unwell. There are some people though who might be affected by phone masts. A large study is just beginning to try to spot these hypersensitive people.
[G]In order to dissolve such doubts, one examiner visited a "sick-mast village", which has one of the highest concentration of masts in the country. The residents—with tin-foil shielding in their houses—are living in fear. They are convinced that the masts are causing a host of symptoms. Are their problems caused by the masts, or could they be caused by worry?
【C2】
