What you eat plays a major role in weight gain. Eating a lot of fattening foods such as hamburgers, sweet
13、 drinks, ice creams and other sweet and fatty foods can increase the risk of becoming obese. If you do not do enough exercise you will put on weight as the food you eat is not being used to make energy for physical activity. The chances of you being obese are greater if your parents are obese. There
14、 are many psychological factors that cause people to eat too much. People who are stressed, unhappy or bored will often eat to make themselves feel better. This is known as comfort eating. Age is another factor, as you get older you tend to be less active. The amount of muscle in your body usually d

Doudna for the development of a method for gene editing.Charpenti
19、er and Doudna have discovered one of gene technologys sharpest tools: the CRISPR/Cas9 genetic scissors. Using these, researchers can easily change the DNA of animals and plants. This technology has had a great impact on the life sciences. It is contributing to new cancer treatment and may make the d
20、ream of curing inherited diseases (遗传病) come true.Researchers need to modify genes in cells if they want to find out about lifes inner workings. This used to be difficult and sometimes impossible. Using the CRISPR/Cas9 genetic scissors, it is now possible to change the code of life in a few weeks.Th
21、e discovery of these genetic scissors was unexpected. During Charpentiers studies of Streptococcus pyogenes (酿脓链球菌), which cause the most harm to humans, she discovered a previously unknown molecule (分子), tracrRNA. It kills viruses by breaking their DNA. She started working with Doudna, an experienc
22、ed biochemist in 2011. They then reprogrammed the genetic scissors. In their natural form, the scissors recognize DNA from viruses, but Charpentier and Doudna prove that they could be controlled so that they can cut any DNA molecule at a given site. Then it is easy to rewrite the code of life.Since
23、Charpentier and Doudna discovered the CRISPR/Cas9 genetic scissors, their use has exploded. This tool has contributed to many important discoveries in basic research, and plant researchers have been able to develop crops that can fight pests and drought. Clinical trials (临床试验) of new cancer treatmen
24、ts are under way, and the dream of being able to cure inherited diseases is about to come true. These genetic scissors have taken the life sciences into a new page and, in many ways, are bringing the greatest benefit to humans.24. Why do scientists place importance on CRISPR/Cas9?A. It makes modifyi

26、 A. It kills harmful viruses. B. It damages human organs. C. It makes DNA copying easier. D. It cuts DNA molecule at a chosen spot.CGenetic testing offers people insight into the types of diseases they are most likely to develop, but a new study suggests most people do not alter their lifestyles bas
27、ed on this information. These tests, known as genome sequencing, analyse a persons DNA, telling patients about their known risk for diseases like cancer or diabetes. But being told youre at a higher risk for lung cancer doesnt seem to motivate anyone to quit smoking or alcohol, this study suggests.
28、Because of this, the scholars argue that genetic testing should be banned as a tool for improving peoples health.Receiving information about genetic risks didnt inspire people to eat differently, exercise more, or stop smoking, “Expectations have been high that giving people information about their
29、genetic risk will empower them to change their behaviour, but we have found no evidence that this is the case,” said Theresa Marteau, director of behaviour and health research in a press release. Genetic testing costs from $100 to $ 2,000 has become much more accessible as 23andMe, Sure Genomics and
30、 etc. have sprung up. These commercial testing companies are not allowed to share disease risk estimates with consumers thanks to the Food and Drug Administration. However, todays study didnt specify whether the genetic testing were purely from academic sequencing, or if any of these companies had h
31、ad a role in supplying the data. Genetic testing doesnt get people to change their behaviour for the better, but it doesnt have any known negative effects either. Knowing the results of these tests didnt change peoples depression or anxiety levels. And theres no indication that testing inspires peop
