1 . Teenagers' fitness is now a major concern, to which physical exercise is very important. It reduces stress and improves fitness. Exercise makes your body strong, and helps you to keep the right body weight. Sports scientist Dr. Helen Lopez offers the following advice to teenagers: "First, you need to find out your present level of fitness.Then you can design a programme that will help you become healthier."
Dr. Lopez suggests that there are three levels of fitness that need a change of lifestyle. "Overweight" means that the person gets very little exercise and often has a serious weight problem."Inactive" means that the person does not join in many physical activities, but is not seriously overweight. "Active" refers to people who take part in sports and other physical activities, but are not at a high fitness level.
According to Dr. Lopez, overweight teenagers should keep active to keep healthy. "Ride a bike, play volleyball or basketball for a while, and go for a twenty- minute walk each day. All these will help to burn calories." Inactive teenagers should do similar activities, but add some bending and stretching exercises, such as push-ups and sit-ups, starting with twenty each day. "Inactive people can take a little more exercise than overweight people because their bodies are stronger," said Dr. Lopez. The same principle applies to active teenagers.
Dr. Lopez suggests one hour a week or more on running and other forms of intensive exercise (强化训练), together with fifteen minutes a day spent on stretching and bending activities. "These are really important in order to prevent injuries," Dr. Lopez said. Some weight-training and other body-strengthening exercises could also be planned in the programme in order to increase the person's strength.

3 . Exercising regularly not only helps you keep slim, but also improves your overall health and well-being. Different exercises produce different results, as they focus on alternate parts of the body. There are four broad exercise categories: endurance, strength, flexibility, and balance. Many people often only focus on one exercise type, but including all four in your workout will produce better results and reduce your risk of injury.
Endurance
Endurance exercises increase your breathing and heart rate. By doing endurance exercises, you are working to keep your heart, lungs, and blood-flow system healthy while improving your total fitness. Over time these activities will make everyday activities seem easier.
Strength
If you want to build up your muscles, then strength exercises, which are also known as “resistance training”, are right for you. Even the slightest increase in strength can make a huge difference in your ability to carry out daily tasks. Developing strong muscles also reduce your risk of weak bones.
Flexibility
Flexibility exercises help stretch your body’s muscles. This allows for more freedom of movement for other exercises and can also improve your range of motion, posture, ability to breathe deeply, and blood flow. Also, it reduces the muscle tension caused by stress.
Balance
Balance exercises help prevent falls and are especially important to older adults, helping them stay independent. Most good balance exercises are ones that keep you constantly moving with your feet on the ground. Heel-to-toe walking and standing on one foot are simple ways to improve balance.

5 . Moments after figure skaters finish their program, fans throw gifts onto the ice. There have definitely been some strange ones over the years. As NBC Sports reports, Sasha Cohen was once given sweaters; Canada’s Elvis Stojko and Patrick Chan walked away with lingerie (内衣); Debi Thomas even got a box of Domino’s pizza after her performance at the 1987 world championships because Thomas had wondered why people “don’t throw something good, like pizza”.
The post-program offerings are mostly stuffed (填充的) animal toys. Though it’s not clear exactly how or when this custom began, people really like to use them as gifts. Flowers, once the popular item to throw at skaters, are messy. The cleaners—the kids who skate around to collect all the gifts between programs—have a much easier time to deal with stuffed toys than fighting with every leaf that fell off the flowers.
There’s no global ban (禁令) on sending flowers, but organizations have made attempts to discourage the practice in the past. In 1989 US Figure Skating banned arenas (圆形运动场) hosting national championships from selling flowers.
“Flowers have always been a problem. The flowers and leaves can appear during the course and become a risk. So flowers on the arena are going to vanish. It is just a question of when.” said Larry Kriwanek, chair of the event’s organizing committee. Instead, fans could buy already-authorized stuffed toys inside the arena and show their favorite skaters with those.
Stuffed toys also give supporters an opportunity to choose presents that suit their favorite skaters characters. “We will sometimes get stuffed toys made in custom costumes to match what we’re wearing,” American ice dancer Meryl Davis, who won gold with partner Charlie White in 2014, told NBC Sports. It turns out that skaters often do try to take especially meaningful or thoughtful gifts home with them.

7 . What are the limits of the human body? Is there a point at which it is physically impossible to do something?
“One thing we’ve all learned in the last 30 years or so is that just about anything is humanly possible,” says Dr. Jack Wilmore, author of Physiology of Sport and Exercise. “As time goes by, I think you’ll see more records continue to fall in every sport. The talent pool is better than ever. With more and better athletes involved and competing, records will fall and new standards will be set.”
Many believed it was physically impossible for a human to run a mile in under four minutes, but Roger Bannister proved that theory wrong with a three-minute, 59-second mile in 1954. Today, sub-four-minute miles are considered routine even in high school. And Bob Beamon stretched human performance in the 1968 Olympics with his historic long jump of 8.90 metres. In an event where a record is usually broken by mere inches, he broke the previous jump record by more than 21 inches, but even his record was broken in 1991.
One factor is now becoming more understood and heavily emphasized: sports psychology. Getting inside the athlete’s head can be as effective as training and long workouts. According to Wilmore, the psychological aspect of sports has become more and more esteemed. He points out that most professional teams have hired sports psychologists for their players.
In addition, every aspect of athletics --- training, nutrition, injury treatment --- is far better than it’s ever been. “Besides, children today tend to specialize in one or two sports instead of competing in several as was common twenty-five years ago,” Wilmore says. “That means they start concentrating on a sport much earlier and more intensely, and they become much better at it.”
“There’s a lot we don’t know yet about the human body,” he adds. “And one of those things is the full range of human potential. It would be foolish to try and put limits on what the human body can do.”
1. Which statement will Wilmore probably agree with?A.It is preferable to set universal standards for athletes. |

D.They become more skilful at one particular sport. |
8 . A hot-blooded carnival for football fans is around the corner! FIFA World Cup Qatar(卡塔尔)2022 will be a special treat since it’s the first World Cup held by a country that has not participated in the World Cup FIFA WORLD CUP before, and also the first time to be held in a Middle Eastern country.
First let’s talk about its mascot(吉祥物), La’eeb, shaped like a walking headscarf, is an avatar (化身)with no fixed shape. This Arabic word means a highly skilled player. The mascot wears a rope and is soft, whose body can make various and difficult movements at will-it gives fans full imagination. The design of the mascot is very novel(新颖的)and this playful image is loved by many fans. Its facial expression is full of determination with an inspirational, upward and positive attitude, just like a strong-willed athlete who never gets discouraged in the face of difficulties.
Considering the high temperature of about 50 degrees in Qatar in summer will affect the athletes’ competitive status, this World Cup is the first time to be held in the northern hemisphere in winter. To successfully hold this World Cup, the Qatar government has invested a huge amount of money in the construction of venues and supporting transportation, communication, accommodation, even with over 1, 000 luxurious Bedouin-style tents in the desert, etc. Service facilities, with a total investment of 220 billion US dollars, make it the most expensive World Cup game at present.
This World Cup will even be the very first carbon-neutral tournament, and the organizer has prepared a total of 8 stadiums, all built to be energy efficient. One of our favorites is Stadium 974, the first fully demountable(可拆卸的)stadium, built using 974 shipping containers, whose number also happens to be Qatar’s country code. The opening game and the final match will be held in the same stadium-Lusail Stadium. Moreover, thanks to Qatar’s efficient public transportation, football fans will need just under one hour of traveling time between stadiums.
And the World Cup final will take place on December the18th, also Qatar’s National Day. So, expect fireworks all around. And let’s have a blast together!

10 . Running on the beach is completely different from running on the pavement, a track or trails with soft surfaces.
For starters, sand can be a challenge because it has an uneven(不平的) surface and constantly moves under your feet. As you push off, you’re going to lose some of your push as the sand moves, so you’re not going to be able to push yourself forward as you would on a track or pavement! But this unevenness has an upside: it gives your body an extra workout, forcing you to exercise the muscles that don’t get as much use as runs on firm surfaces.
You also might feel painful afterward because beaches tend to slope(倾斜) downward, toward the water. If you’re going for a long run on the beach, you might notice that one side of your body including your ankle, leg or knee might feel more painful because you’re putting more pressure on it due to the slope.
Some beach runners tend to run barefoot. However, if you’re not used to barefoot running, start slowly and run short distances at first. That’s because running barefoot uses different muscles than running with shoes does, and it’s important to strengthen these muscles and adapt your feet.
Despite these challenges, running on sand can be a smart choice for athletes because running on it can decrease the bad influence on your body during high-intensity workouts. This could potentially lead to less muscle damage and less pain. Women had less myoglobin (肌红蛋白), which can cause muscle pain, in their blood after running on the sand than they did after running on grass. This suggests running on softer ground surfaces, such as sand, may reduce muscle damage.
1. Why do the starters feel hard while running on sand?A.Because the surface is even. | B.Because the beach is near water. |
C.Because the runners lack muscles. | D.Because the surface of the sand is soft. |
A.A positive aspect. | B.A wide roadside. |
C.An extra workout. | D.A bad influence. |
A.Starting quickly. | B.Not running too long. |
