Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

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 travelling 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

Dịch nghĩa:

“Ngày nay, hàng triệu người đang sử dụng điện thoại di động. Ở nhiều nơi, không sử dụng điện thoại di động thực sự được coi là điều bất thường. Ở nhiều quốc gia, điện thoại di động rất phổ biến với giới trẻ. Họ thấy rằng điện thoại không chỉ là một phương tiện giao tiếp - việc sở hữu một chiếc điện thoại di động cho thấy họ là người "cool" và kết nối.

Sự bùng nổ trong việc sử dụng điện thoại di động trên toàn thế giới đã khiến một số chuyên gia y tế lo lắng. Một số bác sĩ lo ngại rằng trong tương lai, nhiều người có thể gặp phải các vấn đề sức khỏe từ việc sử dụng điện thoại di động. Ở Anh, đã có một cuộc tranh luận nghiêm trọng về vấn đề này. Các công ty điện thoại di động lo ngại về sự công kích tiêu cực đối với những ý tưởng như vậy. Họ nói rằng không có bằng chứng cho thấy điện thoại di động có hại cho sức khỏe.

Mặt khác, các nghiên cứu y học đã chỉ ra sự thay đổi trong các tế bào não của một số người sử dụng điện thoại di động. Các dấu hiệu thay đổi trong mô não và đầu có thể được phát hiện bằng các thiết bị quét hiện đại. Trong một trường hợp, một nhân viên bán hàng phải nghỉ hưu khi còn trẻ vì mất trí nhớ nghiêm trọng. Anh ta không thể nhớ ngay cả những công việc đơn giản. Anh ấy thường xuyên quên tên của chính con trai mình. Người đàn ông này thường xuyên nói chuyện trên điện thoại di động khoảng sáu giờ mỗi ngày, mỗi ngày trong tuần làm việc, suốt vài năm. Bác sĩ gia đình của anh ta cho rằng việc sử dụng điện thoại di động là nguyên nhân, nhưng bác sĩ của nhà tuyển dụng không đồng ý. Vậy điều gì khiến điện thoại di động có thể gây hại? Câu trả lời là bức xạ. Các máy móc công nghệ cao có thể phát hiện ra lượng bức xạ rất nhỏ từ điện thoại di động. Các công ty điện thoại di động thừa nhận rằng có một chút bức xạ, nhưng họ nói rằng lượng bức xạ đó quá nhỏ để phải lo ngại.

Khi cuộc thảo luận về sự an toàn của chúng tiếp tục, có vẻ như tốt nhất là nên sử dụng điện thoại di động ít thường xuyên hơn. Hãy sử dụng điện thoại cố định nếu bạn muốn nói chuyện lâu. Hãy chỉ sử dụng điện thoại di động khi thực sự cần thiết. Điện thoại di động có thể rất hữu ích và tiện lợi, đặc biệt là trong các tình huống khẩn cấp. Trong tương lai, điện thoại di động có thể có một nhãn cảnh báo rằng chúng có thể có hại cho sức khỏe. Vì vậy, hiện tại, bạn nên sử dụng điện thoại di động ít thường xuyên hơn.”
