Q: Read the article and select the best answer. Article: Many expensive nutrition additives advertised on TV say they can improve your memory. But only ordinary food and healthy habits have been shown to work. A research team from UCLA (University of California at Los Angeles) has designed a four-step plan to improve your memory in just 14 days. "It sounds like another advertisement, but it really works," says UCLA psychiatry professor Gary Small. The team found the four-step plan improved memory function in teenagers under stress and older people. After a two-week study that included brain-teasers , exercise and diet changes, test subjects' memories worked more efficiently. Here's the programme: Memory training: Train yourself with brain-teasers, crossword puzzles and memory exercises that train verbal skills throughout the day. Healthy diet: Eat five rather than three meals a day. The food should be rich in omega-3 fats (omega-3), such as whole grains and vegetables that contain antioxidants . Having frequent meals helps increase blood glucose , the primary energy source for the brain. Physical fitness: Have regular physical exercise such as walking, basketball or running, every day. Stress reduction : Perform stretching and relaxation exercises. Stress causes the body to release a chemical that can shrink the memory centres in the brain. Before-and-after brain scans showed that test subjects experienced on average a 5 per cent increase in working memory. This suggests they were using their brains more efficiently. They also performed better on a cognitive test. A control group that didn't follow the plan showed no big changes. "We've known for years that diet and exercise can help people keep their physical health, which is a key part of healthy aging," said Small. "But keeping mental health is just as important. Now we have evidence that people can improve their memories through a programme of memory exercises and stress reduction." Question: Why did Small say " It sounds like another advertisement, but it really works"? Options: A: He is satisfied with his programme. B: He is working at another advertisement. C: He wants to advertise his program. D: He wants to improve his memory.

Q: Read the article and select the best answer. Article: Nowadays, more and more teenagers use smart phones, tablets and other mobile devices more than ever before. And the amount of time they spend on these devices is only likely to increase in the future. But are all these changes good? We sometimes call children who are able to use mobile devices and technology easily digital natives. They can text, email, get Wi-Fi, and download. Some experts say that long periods of time spent chatting to friends online, playing video games and listening to mp3s, for example, may possibly change how their brains work. Then there is the question of privacy. All this online activity creates a digital footprint. Every time we share a photo or a post on social media, and every time we search for something on the Internet, information about our activity is stored somewhere. Our inability to control what happens to our children's digital footprint and their personal privacy has big possibilities. It might become normal for companies to ask their employees for their social media qualifications. We are also becoming more aware that companies and governments may be able to 'listen in' on our communications. So it is important to make our children aware of the possible results of over sharing. Another area where the digital world may have a big effect is in education. One worry is that kids who spend a lot of time online at home are sometimes unable to socialize properly with other children when they are at school. Other experts point out that, when it comes to children and technology, the children are the experts, not the teachers. They say that we should stop seeing online as 'bad' and offline as 'good' and there is evidence of innovative work in some schools. So, do we really need to rescue our children from the dangers of the digital world? Question: All the following may happen to our digital footprints EXCEPT _ Options: A: When surfing the Internet, our digital footprints are saved. B: Some business societies may take advantage of the information. C: Government may look into our communication through the Internet. D: Digital pictures may be printed by our computer automatically.
