How long you live has a lot to do with your environment and lifestyle, but exceptional(特别的)long life may have even more to do with your genes. For the first time, researchers have discovered a genetic recipe(基因谱)that accurately predicts who may live to 100 and beyond.
Analysis shows that 90% of the participants who lived to 100 had at least one of the signature genetic clusters(标志基因组). Dr. Thomas Perls at the Boston University School of Medicine said, “We realize this is a complex genetic puzzle. There is a long way for us to go to understand how the integration(融合)of these genes—not just with themselves but with environmental factors—is playing a role in this long life puzzle.”
Perls has studied many factors that contribute to long life, and he is the first to acknowledge that living longer isn’t likely to be simply a matter of genes. His previous work has shown, for example, that among most elderly people who live into their 70s and 80s, about 70% can owe their long life to environmental factors such as not smoking; eating a healthy, low-fat, low-calorie diet; and remaining socially engaged and mentally active throughout life.
It seems clear that those who live extremely long are benefiting from a special DNA. In fact, Perls believes that the older a person gets, the more likely it is that his or her genes are contributing to those extended years.
1.Which of the following is TRUE according to Paragraph 2?
A. Most long-living people have special long-life-related genes.
B. Ninety percent of the participants lived to 100 years of age.
C. All the long-living people have only one signature genetic cluster.
D. Scientists know how the integration of the genes helps people live long.
2. Perls may most likely agree that .
A. most people living extremely long benefit from not smoking
B. living longer just depends on certain genetic recipes
C. environmental factors play an important role in long-living
D. being mentally active has nothing to do with living an old age
3. Which of the following is FALSE according to the text?
A. Remaining socially engaged helps a person to live long.
B. A genetic recipe can accurately predict who may live to 100 and beyond.
C. Perls is the first to think living longer is just a matter of genes.
D. The older he gets, the more likely the genes contribute to his extended years.
4.Which of the following would be the best title for the text?
A. Genes May Predict Who Lives to 100 B. Environment And Genes
C. Genes, the Secret of Long Living D. Lifestyle And Genes
