Millions of people are using cell phones today. In many places, it is actually considered unusual not to use one. In many countries, cell phones are very popular with young people. They find that the phones are more than a means of communication - having a mobile phone shows that they are cool and connected.

Millions of people are using cell phones today. In many places, it is actually considered unusual not to use one. In many countries, cell phones are very popular with young people. They find that the phones are more than a means of communication - having a mobile phone shows that they are cool and connected.

The explosion in mobile phone use around the world has made some health professionals worried. Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. In England, there has been a serious debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. They say that there is no proof that mobile phones are bad for your health.

On the other hand, medical studies have shown changes in the brain cells of some people who use mobile phones. Signs of change in the tissues of the brain and head can be detected with modern scanning equipment. In one case, a traveling salesman had to retire at young age because of serious memory loss. He couldn't remember even simple tasks. He would often forget the name of his own son. This man used to talk on his mobile phone for about six hours a day, every day of his working week, for a couple of years. His family doctor blamed his mobile phone use, but his employer's doctor didn't agree.

What is it that makes mobile phones potentially harmful? The answer is radiation. High-tech machines can detect very small amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they say the amount is too small to worry about.

As the discussion about their safety continues, it appears that it's best to use mobile phones less often. Use your regular phone if you want to talk for a long time. Use your mobile phone only when you really need it. Mobile phones can be very useful and convenient, especially in emergencies. In the future, mobile phones may have a warning label that says they are bad for your health. So for now, it's wise not to use your mobile phone too often.

Doctors have tentatively concluded that cell phones may ____________.

A. change their users’ temperament

B. have damaged their users’ emotions

C. cause some mental malfunction

D. change their users’ social behaviours

A. Chúng khiến người dùng cảnh giác mọi lúc

B. Chúng không thể thiếu trong giao tiếp hằng ngày

C. Chúng làm họ trông sành điệu hơn

D. Chúng không thể thay thế bởi điện thoại thông thường

Dẫn chứng câu cuối đoại 1 “They find that the phones are more than a means of communication - having a mobile phone shows that they are cool and connected.” – (Họ thấy rằng điện thoại có hơn 1 ý nghĩa là giao tiếp-có 1 chiếc điện thoại cho thấy rằng họ ngầu và có nhiều mối quan hệ)

Dịch bài

Có hàng triệu người đang sử dụng điện thoại di động ngày nay. Ở nhiều nơi, nó thậm chí bị coi là bất thường nếu ta không sử dụng 1 chiếc. Ở nhiều quốc gia, điện thoại di động rất phổ biến đối với giới trẻ. Họ nhận thấy rằng điện thoại không chỉ đơn thuần là 1 phương tiện giao tiếp mà chúng còn chứng minh rằng họ ngầu có mối nhiều quan hệ

Sự bùng nổ trong sử dụng điện thoại di động trên khắp thế giới đã khiến một số chuyên gia y tế lo ngại. Một số bác sĩ sợ rằng trong tương lai nhiều người có thể gặp vấn đề về sức khoẻ do sử dụng điện thoại di động. Tại Anh, đã có một cuộc tranh luận gay gắt về vấn đề này. Các công ty điện thoại đang lo lắng về việc công chúng sẽ biết đến những ảnh hưởng xấu của điện thoại di động. Họ nói rằng không có bằng chứng nào cho thấy điện thoại di động có hại cho sức khoẻ của người dùng.

Mặt khác, các nghiên cứu y học đã cho thấy có sự thay đổi trong tế bào não của một số người đang sử dụng điện thoại di động. Dấu hiệu thay đổi mô trong não có thể được phát hiện bằng thiết bị quét hiện đại. Trong một trường hợp, một nhân viên bán hàng đã phải nghỉ hưu khi còn rất trẻ vì chứng mất trí nhớ nghiêm trọng. Anh ta không thể nhớ ngay cả những nhiệm vụ đơn giản và thường xuyên quên cả tên của con trai mình. Người đàn ông này thường nói chuyện điện thoại di động khoảng sáu giờ mỗi ngày trong tuần làm việc của mình trong một vài năm. Bác sĩ gia đình đổ lỗi cho việc sử dụng điện thoại di động , nhưng bác sĩ công ti thì không đồng tình

Điều gì làm cho điện thoại di động có khả năng gây hại như vậy? Câu trả lời là bức xạ. Các máy móc công nghệ cao có thể phát hiện ra một lượng nhỏ bức xạ từ điện thoại di động. Các công ty điện thoại di động đồng ý rằng có một vài bức xạ, nhưng họ nói rằng số lượng đó rất nhỏ để phải bận tâm

Thảo luận về sự an toàn khi tiếp tục sử dụng, cách tốt nhất là sử dụng ít thường xuyên hơn. Dùng điện thoại thông thường nếu là cuộc nói chuyện dài. Chỉ sử dụng điện thoại di động khi bạn thực sự cần. Điện thoại di động có thể rất hữu ích và thuận tiện, đặc biệt là trong trường hợp khẩn cấp. Trong tương lai, điện thoại di động có thể là 1 cảnh báo rằng chúng không tốt cho sức khoẻ của bạn. Vì vậy, ngay từ bây giờ, hãy khôn ngoan khi không sử dụng chúng quá thường xuyên
