Reducing the number of calories every day is the ticket to good health. It works in lab animals. It also works in human     1     (being). The name of the method is “caloric restriction”. It increases the life length of animals. It even reduces their rate of cancer and other diseases     2     happen as people age. Reducing calories usually     3     (make) a difference to young and middle-aged adults.

Researchers looked into     4     group of healthy men and women aged between 21 and 50. Members of the group agreed to reduce calories for two years. They could eat the foods they wanted as long as they cut back     5     the total amount of food they ate. They     6     (expect) to cut calories by 25 percent by the researchers.

Many could not do it. The average calorie reduction was twelve percent. That is a reduction of     7     (approximate) 300 calories a day. But it worked. Those     8     (practise) calorie reduction lost weight and body fat. Their blood pressure fell a little. Fewer calories lead to better health, Does it lead to a longer life and     9     (little) sickness? A doctor said the diet would have to last a long time     10     (find) out the answer to this question. Researchers would have to study people for a lifetime to know whether the diet keeps them well and alive longer.

3 . As a hockey parent, while watching my son played from Mite to Bantam, House League to Travel, I’ve learned that losing may be best for kids.

In his third season in 2019, my son’s team never lost more than three straight games. There was happiness, boasting, celebration, pizza. In short, it was a typically good youth hockey season. He improved as a player, but did not much change as a person.

However, what happened the next year added its story to the legends of sporting incompetence. Not merely weak but prettily bad, this team lost 40 of their first 50 games, most of the defeats coming in the course of two losing streaks. For a time, I worried that these streaks would kill my child’s love of the game.

But that’s not what happened. As bad as it got, the losing was clarifying. It weeded out the kids who were in it less for the game than the glory, leaving just the die-hards behind. What started as a list of 17 of the team was cut down to 12. It was especially instructive for the kids. It taught him a great truth of the world: For everyone good, there is someone better.

What’s more, the kids were learning the game in a way that only losing can teach. Each player got to play everywhere, to learn and appreciate the role of every position on the ice. They kept an eye on their opponents too, studying and incorporating the tricks of success. In an effort to break the streak, they went back to basics, accepted the wisdom of the hockey ancients: If playing like a team, they can defeat a collection of all-stars; If doing small and unappreciated tasks well, they can get the goal.

This new team had character and could never be counted out, no matter the score. They had learned the most important lesson: You can lose without being beaten. They squeaked into the state tournament, then made it all the way to the final, where the winner was decided in overtime. When they lost that game and went into the handshake line, it was not as runners-up but as a team that had been made into winners in the only way that will stick — by losing.

Wearing wristbands with the names of LeBron James and Kobe Bryant     1     (write) on them, 17-year-old Tibetan girl Cigla plays her favorite sport — basketball — at Nagqu No 2 Senior High School in Lhasa, Tibet Autonomous Region. For her,     2       (study) in Lhasa, the region’s most developed city, has made it much     3     (easy) for her to realize her basketball dream.

With     4       average altitude of over 4,500 meters, Nagqu is among the most uninhabitable places in Tibet.     5     have long compromised the health of Nagqu students are low-oxygen environment and extreme weather. “The students had barely played any sports due to     6       (limit) sports facilities and frequent bad weather in Nagqu.” said Bachug, the school's physical education teacher.

However, in a bid to ensure equal access     7     quality education, in recent years, the Tibet regional government     8       (establish) several schools in Lhasa to recruit Nagqu students. Like Cigla, many Nagqu students are from poor farming and herding families. The school     9       (campus) in Lhasa have seven concrete basketball courts, a standard soccer field and a sports stadium, which gives students opportunities     10       (train) their bodies and find the sport that appeals to them.

8 . The most important lesson that sports of all kinds teach us is a sense of discipline. A good sportsman must always learn to obey the rules of the games and the orders of the captain. Lawlessness has ruined many a promising career. The sportsman is never lawless.     1     He knows the value of the proverb—“He who knows how to obey will know how to command.”

Discipline goes hand in hand with duty. On the playground, each individual has his own duty to perform.     2     It is his duty to help in winning games by obeying his captain. Discipline, duty, obedience. This is the great moral triangle that contributes to a strong character. Another great virtue which sports help us acquire is the will to win. Life is a struggle, a constant fight against difficulty, against disappointments. A sportsman takes defeats and disappointments as true parts of the game.     3     Today he is defeated, but he knows that tomorrow he may win.

    4     Look at the rowers in a boat; how harmonious are their strokes (划桨). If one of them misses his rhythm the harmony is destroyed. It is the same in the football field; the same everywhere. Unity of action is the great lesson which we can learn from sports.     5     The lessons learned on the playground will make better soldiers of us in the battle-field of life.
