The team said they had identified a matter 8-oxoGsn that indicated increases in oxidative (氧化性) damage in urine as peoples bodies aged.Cai Jianping, a co-author at the Beijing Hospital, said: “As we age, we suffer increasing oxidative damage and so the levels of oxidative matters increase in our body.” The team tested the levels of 8-oxoGsn in urine samples from 1,228 Chinese people aged two to 90 and concluded the marker helped accurately determine the stage of biological ageing in adults.They had previously found that 8-oxoGsn levels also increased with age in the urine of animals such as mice.The team has also developed a rapid analysis technique called ultra-high-performance liquid chromatography, which can process up to 10 urine samples an hour, according to the study.1. Scientifically speaking, by what does a doctor judge the stage of a person getting old? A. His condition.B. His biological age. C. His psychology.D. His chronological age.2. What are the outer factors the speed of ones ageing physically depend on?A. Ones birth date.B. The increases in oxidative damage in urine.C. The changes in their genetic make-up and their environment.D. The accumulation of various molecular faults in the bodys cells.3. Which can take the place of the underlined word “marker” in the sixth paragraph?A. 8-oxoGsn.B. Molecular faults.C. Oxidative damage.D. Stage of biological ageing in adults.4. What is the passage about?A. Why people are ageing.B. How to delay peoples ageing physically.C. What determines the stage of peoples ageing physically.D. A rapid method with which to judge how much people are aging physically.B BI was born in a poor family, 8 siblings, and life was hand-to-mouth. If I recall my family experience, I would say each day was a challenge to keep our stomachs filled.At 18, I gave up a chance to study at a local university. I started working as a salesman because I knew it paid high returns if I could work harder. I worked for Olivetti selling manual and electric typewriters, themes-copiers and calculators.I put in a lot of time and efforts to learn the products so that I could demonstrate better. Every morning I carried a manual typewriter and shouldered an electric one, from the office to my destination about 2 miles away. I have to carry them because it took very long to arrange a demo(演示) unit through the office protocol(协议), and I was motivated to sell with my sweat and tears.The next 20 years I worked harder than graduate workers because jobs for non-graduates were few and low with pays.I understand the reasons why I have to work so hard for extra miles. But no regret, and I cannot let this problem to happen to my children. I must ensure they get to pass the tertiary(高等的) education and at least reach the fundamental standards in their career. I then paid for their education fees.My children understood and saw the simple lifestyle that my wife and I are having. They say they will repay after they step into employment. They made their grades one by one, and all are working now.I told my children my past and let them know I gave them wings, but they must know the root! I hope this conscious education will pass through the generations!5. What can we know from the first paragraph? A. The writer didnt have enough food to eat. B.
