雅思TASK2大作文模拟题:交流 Communication

Mobile phones are becoming increasingly popular nowadays, and the number of people using them has grown hugely, especially in developing countries. There is some debate about the safety of mobile phones, but in my opinion, the benefits from these phones are far greater than any possible health risks. There is some concern that mobile phones may cause brain damage or cancer because of the radiation they emit while they are being used. Some people are also worried that cell phone towers may be bad for health. However, researchers have conducted experiments over many years to find out if this is true, and so far they have found no evidence for this. On the other hand, mobile phones have many benefits, both for individuals and for isolated communities. They help individuals to communicate quickly and easily, and they can be used both for social reasons and in emergencies. For example, people can use them to contact their friends and, if they use texting, the phones are cheap and convenient. They are also very useful if someone has an accident while driving. In addition, isolated communities which do not have land lines can use mobile phones to contact the outside world, and this is much cheaper than installing land line phones. In conclusion, although some people are worried about the health risks of cell phones, there is little or no evidence for this. However, there is a lot of evidence for the benefits of cell phones, so in my opinion we should not worry about the dangers of cell phone use.
