A super drug that could remove Alzheimer’s (老年痴呆症)，heart disease and diabetes (糖尿病) and help people live to 100 is being developed by scientists. Their research is based on the identification of three genes that help prolong lives and prevent diseases which occur in old age. Medically controlling the proteins made by the “ longevity genes” will allow millions to live longer, predicts Dr Nir Barzilai.
Those whose DNA strongly features the three genes are 80 percent less likely to develop Alzheimer’s. The genes also fight against the deadly impact of smoking, poor diet, obesity and lack of exercise.
Already, several laboratories are working on a pill to imitate the benefits of the genes and Dr Barzilai thinks it could be tested within three years. The pill could remove some diseases that damage old age. “ The advantage of finding a gene that involves longevity is that we can develop a drug that will imitate exactly what this gene is doing,” he said.
Of the three longevity genes, two genes increase the production of so-called good cholesterol(胆固醇), which reduces the risk of heart disease. The third prevents diabetes. They were discovered by Dr Barzilai’s team while studying the DNA of 500 Ashkenazi Jews with an average age of 100. The chances of living that long are one in 10,000 but the group, which shared relatively few common ancestors, was 20 times more likely to hit the entury. Dr Barzilai said: “ 30 percent of them were obese or overweight and 30 percent smoked two acks of cigarettes a day for more than 40 years, however they can live to 100.”
But Andrew Ketteringham of the Alzheimer’s Society said: “Alzheimer’s disease, a most common disease, is likely to be caused by a combination of genetic disosition(遗传倾向), lifestyles and life events. Many genes are probably involved.

【小题4】What is Andrew Ketteringham’s attitude toward the study?

William Henry Bragg was born at Westward，Cumberland，on July 2,1862.He was educated at Market Harboroagh Grammar School and afterwards at King William’s College，Isle of Man.Elected as a minor scholar of Trinity College，Cambridge，in 1881，he studied mathematics under the well?known teacher，Dr E．J.Routh.He studied physics in the Cavendish Laboratory during a part of 1885，and at the end of that year he was elected to the Professorship of Mathematics and Physics in the University of Adelaide，South Australia.

His research interests dealt with a great many fields and he was skilled at picking up a subject，almost casually，making an important contribution，and then dropping it again.However，the work of Bragg and his son Lawrence in 1913～1914 founded a new branch of science of the greatest importance and significance，the analysis of the crystal structure by means of X?rays.It is true that the use of X?rays as an instrument for the systematic revelation of the way in which crystals are built was entirely due to the Braggs.This was recognized by the award of the Nobel Prize jointly to father and son in 1915.

He was an honorary Doctor of some sixteen universities，and a member of the leading foreign societies.Many other medals and awards were bestowed upon him among which may be mentioned the Rumford Medal in 1916 and the Copley Medal (its premier award) in 1930.

He was the author of many books，including Studies in Radioactivity，X?Rays and Crystal Structure，The World of Sound，Concerning the Nature of Things，Old Trades and New Knowledge，An Introduction to Crystal Analysis，and The Universe of Light.His favorite hobby was golf.After a life of astonishing productiveness，Sir William Bragg died on March 10,1942.

1.William Henry Bragg was awarded the Nobel Prize because________.

A．he succeeded in using X?rays to find out the crystal structure

B．he was the first to use X?rays to help to do his experiment

C．he determined to learn everything well and then gave them up

D．he was successful in his research work with the help of his son

2.According to this passage，William Henry Bragg was interested in all the subjects EXCEPT________.

A．mathematics? B．physics

C．medicine? D．sports

3.Which one of the following is TRUE according to this passage?

A．Bragg became a professor in the University of Adelaide in 1885.

B．Bragg won the Rumford Medal and the Copley Medal in the same year.

C．Bragg gained great achievements in many fields，including society.

D．Bragg and Lawrence wrote the book X?Rays and Crystal Structure.

4.Which of the following is the best title for this passage?

A．William Henry Bragg’s Productive Life

B．William Henry Bragg：A Famous Author

C．Bragg and His Son—Two Great Scientists
