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.

A new study     1     (publish) by the Rapid Transition Alliance has revealed that climate change     2     (threaten) global sports events over the next three decades. This group monitors climate change, development and global issues on     3     daily basis. Researchers said that nearly all sports would be affected in the future by     4     they called “an accelerating (加速的) climate crisis”. They highlighted how the weather had already     5     (direct) affected major sports events. Bushfires in Australia made playing conditions     6     (danger) at the Australian Tennis Open. They predicted that fires, floods, heat waves and rising sea levels would cause greater damage.

The Rapid Transition Alliance urged the sports industry     7     (become) carbon-neutral (碳中和的). It said that the carbon emissions from sports events worldwide are equal     8     those produced by a medium-sized country. The study blamed the sport for     9     (it) inaction. It said, “Making a carbon-zero world he common-sense priority (优先) of the sports world would make a huge     10     (contribute) to making it the common-sense priority of all politics.”

The idea of running long distances can be discouraging at first.     1    , with a lot of patience and a baby-step approach, you can steadily develop a solid pace     2     will last for longer and longer stretches, even while you chat with your running partner!

Whether you are only beginning to run or have already made a practice of it, design a training schedule     3     (base) on your current abilities. Forget “no pains, no gains.” Resist the urge     4     (push) yourself too hard or too fast. Keep your runs sensible and achievable, especially in the beginning. Running is an exercise with a risk of     5     (injure), especially for beginners. The tortoise-wins-the-race manner will decrease your chance of hurting     6     (you). If you have little or no miles under your belt, shift between running and     7     (walk) in the beginning. Jog for one minute, and then walk for four. Repeat three more times for a total workout of 20     8     (minute). As the one-minute jogging intervals (间歇) become easier from one workout to the next, double them     9     two minutes each and decrease the walking intervals to three. Continue to increase the jogging and decrease the walking over time until you are     10     (comfortable) running for a total 20-minute stretch.

For the sake of your fitness or slimness, besides dieting—cutting out junk food, you need to participate in sports as well, starting from some easier ones    1    more skillful and    2     (compete) ones, such as doing push-ups, jogging, track and field, soccer(playing the captain is even more interesting), skiing or even boxing and marathon as long as you have enough strength. You can also go to the gym for graceful gymnastics because working out makes you sweat. At the beginning you will find it hard, but before long you will make    3    .

Remember the 2018 Beijing Olympics, which    4    (host) in China as a huge success with numerous spectators? So many international athletes got    5    (involve) in various events,    6    the Chinese athletes did awesome jobs, with some masters    7    (create) legends and championships, winning medals and glory for our countries, and setting amazing examples. Even if they suffered    8     (injure)(sometimes their bones fell apart) and failures now and then, they persevered instead of losing heart or    9    (quit) with positive and strong determination, believing    10    they have stuck to with willpower will eventually make a difference, which does make sense.
