听力原文: In 1858, a British scientist named William Farr set out to study the "marital condition" of the people of France. He divided the adults into three categories: the "married", consisting of husbands and wives; the "unmarried", defined as the bachelors and spinsters who had never married; and finally the "widowed", those who had experienced the death of a spouse. (29)Using birth, death and marriage records, Farr analyzed the death rates of the three groups at various ages. The work, a groundbreaking study that helped establish the field of medical statistics, showed that much more unmarried people died from disease than the married. And the widowed, Farr found, lived worst of all.
Farr was among the first scholars suggesting that there is a health advantage to marriage. Married people, the data seemed to show, lived longer, healthier lives. "Marriage is a healthy estate," Farr concluded. "The single individual is more likely to be wrecked on his voyage than the lives joined together in marriage."
(30) While Farr's own study is no longer relevant to the social realities of today's world because his three categories don't include couples living together, gay couples and the divorced, for instance, his finding about the health benefits of marriage seems to have stood the test of time. (31)Although better health among the married some times simply reflects the fact that healthy people are more likely to get married in the first place, scientists have continued to prove the "marriage advantage": the fact that married people, on average, appear to be healthier and live longer than unmarried people.

请阅读第二段文本(Text 2),判断并选择你认为该文写作的目标读者是谁? They will never win a beauty contest, but naked mole rats may hold a lesson or two for humans. Two studies in 2013 found clues as to why these rodents can live 30 years, cancer-free. One secret may be the ribosome that excels at producing error-free proteins; misformed proteins can clog up the body’s systems and accelerate aging. Another could be a supersized version of complex sugar that seems to protect against cancer. Naked mole rats don't break this compound down as fast as other animals, so it builds up in the spaces between cells and may keep the cells from clumping together and forming tumors.

听力原文: Before World War II, we spent our summer holidays in Hungary. I have only the dim memory of the house we lived in, of my room and my toys. Nor do I recall clearly the large family of grandparents, aunts, uncles and cousins who gathered next door. But I do have a clear memory of the dogs, the farm animals, the local birds, and above all, the nature.
I'm a naturalist, not a scientist. I have a strong love of the natural world and my enthusiasm has led me into varied investigations. I love discussing my favorite topics and enjoy burning the midnight oil while reading about other people's observations and discoveries. Then something happens that brings these observations together in my conscious mind. Suddenly you fancy you see the answer to the riddle, because it all seems to fit together. This has resulted in my publishing 300 papers and books, which some might honor with the title of scientific research.
But curiosity, a keen eye, a good memory and enjoyment of the animal and plant world do riot make a scientist: one of the outstanding and essential qualities required is self-discipline, a quality I lack. A scientist requires not only self-discipline but hard training, determination and a goal. A scientist, up to a point, can be made. A naturalist is born. If you can combine the two, you get the best of both worlds.

New Product Will Save Lives
Drinking water that looks clean may still contain bugs(虫子),which can cause illness. A small company called Genera Technologies has produced a testing method in three stages, which shows whether water is safe. The new test shows if water needs chemicals added to it, to destroy anything harmful. It was invented by scientist Dr. Adrian Parton, who started Genera five years ago. He and his employees have developed the test together with a British water company.
Andy Headland, Genera’s marketing director, recently presented the test at a conference in the USA and forecast good American sales for it. Genera has already sold 11 of its tests at $ 42,500 a time in the UK and has a further four on order. It expects to sell another 25 tests before the end of March. The company says it is the only test in the UK to be approved by the government. Genera was formed five years ago and until October last year had only five employees; it now employs 14. Mr. Headland believes that the company should make around $19 million by the end of the year in the UK alone.
Genera Technologies has developed a method that determines whether water is clean.
A.Right
B.Wrong
C.Not mentioned
