9:19 Lesson 5 Mental Toughness Section 2 * 2 Stay focused. Relax. 5G |連続 -X 83% You might be surprised that even 押し続けると world-class athletes get nervous and - lose confidence. Roger Federer is one of the greatest tennis players of all time. He is the winner of 20 Grand Slam tournaments. You might think that he would have no problems keeping up his self-confidence. You would be wrong. Roger Federer is sometimes plagued with negative thoughts. He was playing a match which he had perfectly prepared for, yet somehow he was losing. When asked how he felt, he said, "No matter how positive you are, you just see negativity flying all around you." So what is his advice? Accept all the difficult thoughts and feelings and just stay focused on the game.

5 Reading Passage 10 15 20 Yuna Kim is one of the world's best figure skaters. At the 2010 Winter Olympics in Vancouver, she set three world records. In fact, one of those world records broke a record she set in 2009. program and a At the Olympics, both male and female skaters perform a short seven program. In the short program, skaters have less than three minutes to perform required jumps, spins, or other moves. While doing these seven things, the skaters also have to show judges how well they can put these elements together into a kind of dance performance on the ice. The long program is similar to the short program except that skaters perform for a longer time and have more required moves. long Before the 2010 Winter Olympics began, many people thought Yuna Kim was likely to win a gold medal. Certainly, there were other women skaters who had the skill to win gold at the Olympics. However, Ms. Kim had an advantage. She had already set a number of world records. In 2007, she set the record for the highest score in a short program with 71.95 points in Japan. The same year she also set the world record for the highest score in a long program with 133.7 points in Russia. Then, in 2009 she beat her own record in the short program by scoring 76.12 in the United States. At that competition, she also became the first woman to score over 200 points with her short and long programs - her combined score was 207.71. The next year at the Winter Olympics in Vancouver, she broke her records again. In the short program, Ms. Kim scored 78.5, a new world record. In the long program, she scored 150.06, another world record. This gave her a combined total of 228.56 points, a third world record! Needless to say, her score was enough to win gold.

Unit 12 Change the World Basic A few years ago, an obesity* researcher at the University of Washington-named Adam Drewnowski ventured into the supermarket to solve a mystery. He wanted to (1) figure out why (2)poor people were more likely to suffer from obesity in America. Obesity is, as you know, mainly caused by taking in too many calories. For most of history the poor have typically suffered from a shortage of calories, not an excess. So why do the people with the least amount of money to spend on food tend to be overweight today? 目 Drewnowski gave himself a dollar to spend, using it to purchase as many calories as he possibly could. He discovered that he could buy the most calories per dollar in the middle aisles of the supermarket, among the towering piles of* processed food and soft drinks. 3 Processed food is, in the broadest sense, any food that is changed from its natural, raw state. But here, it refers to food which has been chemically changed by using additives* such as flavors, colors, preservatives*, stabilizers*, etc., or which has been combined with other foods in a manufacturing process. Generally speaking, if the ingredients* aren't “natural,” then we consider it to be ( 3 ). Drewnowski found that a dollar could buy 1,200 calories of cookies or potato chips, which are typical processed foods, but only 250 calories of carrots. Looking for something to wash down those chips, he discovered that his dollar bought 875 calories of soda (a processed food) but only 170 calories of orange juice. 5 As a rule, processed foods are more “energy dense*” than fresh foods: they contain less water and fiber but more added fat and sugar, which makes them both (4)less filling and more fattening. 5 These particular calories also happen to be the least healthful ones in the marketplace, which is why we call the foods that contain them "junk*.” Drewnowski concluded that the rules of the food game in America are organized in such a way that if you are eating (6) on a budget, the most rational economic strategy is to eat badly-and get fat.
