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.

From shock came action.They focused on the simple message that one life is worth no more or less than another.Frances Hesselbein,chairman of the non-profit Leader to Leader Institute, says:"Sometimes people give in a very fair way,but there is something about what they are doing...that is the opposite of that.It is very difficult to understand and very personal."

This made him the first Olympic champion in history. Then the Olympic Games developed and continued to be held every four years. In 393 AD, the Roman Emperor Theodosius I, a Christian, put a stop to the Games. In 1892, a young Frenchman named Pierre de Coubertin suggested starting the Olympic Games again but failed. Two years later, Coubertin organized a meeting with 79 people representing nine countries. At this meeting he got what he wanted. All the delegates at the meeting voted for the Olympic Games. They also decided to have Coubertin found an international committee to organize the Games. This committee became the International Olympic Committee (IOC) and Demetrious Vikelas from Greece was chosen to be its first president. Athens was chosen for the revival of the Olympic Games and the planning began. The first modern Olympic Games opened in the first week of April, 1896. Since the Greek government didn't have enough money to build a stadium, a wealthy Greek man, Georgios Averoff, donated over $100,000 to repair the Panathenaic Stadium built in 330 BC.Since the Games were not well publicized internationally, athletes were not nationally chosen but rather came by themselves. Some athletes were tourists who happened to be in the area during the Games. Question: What can we know about the first Olympic Games? Options: A: There was only one event in it. B: It opened in the first week of April 1896. C: Coroebus was the first man to take part in it. D: It was stopped by the Roman Emperor Theodosius I.
