There are some diseases for which we know no cure. For many of these, however, scientists have been able to discover a means of prevention. Smallpox is such a disease.

In the 18th century, millions of people died of smallpox, while many others who recovered from the disease were left scared for life. Today, it is rare to find a case at all.

By 1780, doctors had noticed that once person had smallpox, he became immune to it. From this observation, the theory of inoculation was developed. Inoculation is a way of deliberately giving a person a disease by placing disease matter under the skin. When this is done, the person may develop a mild case of the disease, but from then on he is safe from a severe attack.

Using this principle, an English doctor named Edward Jenner set to work against smallpox. He found that persons who had had a milder disease called cowpox could not catch smallpox. The cowpox seemed to make them immune. By taking some bacteria from the arm of a person who was ill with cowpox, and giving it to a healthy person, Jenner found that he could transfer the immunity. Jenner’s process came to be known as vaccination, from the Latin word “vacca”, meaning “cow”. Because of vaccination, smallpox, one of the man’s greatest enemies, has been practically wiped out.

1. While not directly stated, it may be inferred from the article that__________

A. There is no good cure for smallpox. B. smallpox has almost disappeared.

C. smallpox and cowpox are similar diseases. D. smallpox can disfigure people who suffer from it.

2. This article as a whole tells us__________

A. about an English doctor named Edward Jenner B. all about inoculation.

C. all about vaccination. D. how a terrible disease was conquered.

A. Wiping out smallpox. B. Preventing diseases by prescribing medicine.

C. transferring immunity from one person to another. D. protecting cows from cowpox.

4. Inoculation against smallpox means__________

A. giving a person some medicine to take. B. placing diseased matter under his skin.

C. injecting him with some drugs. D. deliberately coming into contact with smallpox patients.

Mickey Mantle was one of the greatest baseball players of all time. He played for the New York Yankees in their years of glory. From the time Mantle began to play professionally in 1951 to his last year in 1968, baseball was the most popular game in the United States. For many people, Mantle symbolized the hope, prosperity, and confidence of America at that time.

Mantle was a fast and powerful player, a “switch-hitter” who could bat both right-handed and lefthanded. He won game after game, one World Series championship after another, for his team. He was a wonderful athlete, but this alone cannot explain America’s fascination with him.

Perhaps it was because he was a handsome, red-haired country boy, the son of a poor miner from Oklahoma. His career, from the lead mines of the West to the heights of success and fame, was a fairy-tale version of the American dream. Or perhaps it was because America always loves a “natural”: a person who wins without seeming to try, whose talent appears to come from an inner grace. That was Mickey Mantle.

But like many celebrities, Mickey Mantle had a private life that was full of problems. He played without complaint despite constant pain from injuries. He lived to fulfill his father’s dreams and drank to forget his father’s early death.

It was a terrible addiction that finally destroyed his body. It gave him cirrhosis of the liver and accelerated the advance of liver cancer. Even when Mickey Mantle had turned away from his old life and warned young people not to follow his example, the destructive process could not be stopped. Despite a liver transplant operation that had all those who loved and admired him hoping for a recovery, Mickey Mantle died of cancer at the age of 63.

What is the main idea of the passage?

A. Mickey Mantle’s success and private life full of problems

B. Mickey Mantle as the greatest baseball player of all time

C. Mickey Mantle and the history of baseball

D. Mickey Mantle and his career as a baseball player

Gluten-free diet should not be eaten by people who are not coeliac, say scientists

Gluten-free diets should not be encouraged among people who do not have coeliac disease, scientists have said. Gluten is a protein found in wheat, rye and barley and gives food a chewy texture and elasticity during the baking process.

Around one per cent of Britons are genuinely gluten-intolerant, and face a string of debilitating symptoms including vomiting, nerve problems, anaemia, inflammation and an increased risk of coronary heart disease. However some estimates put the proportion of adults adhering to gluten-free diets in the UK at more than 12 per cent, many believing that it is better for the heart.

Researchers at Harvard University looked at data from nearly 120,000 people over 26 years and found that going gluten-free did not cut the risk of heart disease. And they warned that restricting dietary gluten may result in a low intake of whole grains, which are known to be beneficial for the heart.

Thanks nhìu nha !

Theo các nhà khoa học, những người không mắc bệnh celiac thì không nên thực hiện chế độ ăn uống không có gluten
Các nhà khoa học cho biết, chế độ ăn uống không có gluten không được khuyến khích cho những người không mắc bệnh celiac. Gluten là một loại protein có trong lúa mỳ, lúa mạch đen và lúa mạch, tạo tính dai và tính đàn hồi cho đồ ăn trong quá trình nướng.
Khoảng 1% người Anh mắc chứng không dung nạp gluten, và phải đối mặt với một loạt các triệu chứng suy nhược bao gồm nôn mửa, các vấn đề thần kinh, bệnh thiếu máu, viêm và tăng nguy cơ bệnh tim mạch vành. Tuy nhiên, một số ước tính cho thấy tỷ lệ người lớn thực hiện chế độ ăn uống không gluten ở Anh là hơn 12%, nhiều người tin rằng điều đó sẽ tốt hơn cho tim.
Các nhà nghiên cứu tại Đại học Harvard đã xem xét dữ liệu thu thập trên gần 120.000 người trong thời gian trên 26 năm và thấy rằng việc thực hiện chế độ ăn uống không có gluten không làm giảm nguy cơ bệnh tim. Và họ cảnh báo rằng việc hạn chế gluten trong khẩu phần ăn có thể dẫn đến lượng dung nạp các ngũ cốc nguyên hạt thấp, loại mà được biết đến là có lợi cho tim.
