1 . For many Americans, regular exercise is a complicated commitment—one made at the beginning of January that fades out within weeks or months. Busy work schedules, a lack of motivation and unease towards exercising in public all contribute to the discouraging statistics that only around a quarter of adults exercise enough per week.

This month, enterptiser Trent Ward and designer Yves Behar are uncovering their design for a mirror fitness system, Forme. Forme is reflective like a mirror, uses machine learning to heighten workouts, and offers attachments including ankle belts, rope handles and a heart rate monitor. When not in use, the two arms that form the resistance pulley (滑轮) system fold behind it and the display screen disappears, turning Forme into a simple full—length mirror.

Interest in home exercise has particularly increased recently around the world. Home workout apps have seen a significant uptick in downloads, and trendy brands like Peloton have rolled out free virtual workouts for everyone stuck indoors. One French athlete who was kept away from others chose to run an entire marathon on his 23-foot balcony.

But beyond the new restrictions affecting daily workout routines, Ward and Behar are tapping into the same concerns that have made every home workout appealing：the ability to save time and sweat in the privacy of one’s home. In an age of personal metrics (衡量标准)--where one can measure their heart rate and sleep cycles with smart watches and train for marathons with AI smart sneakers----Ward and Behar want to improve exercise through machine learning. Forme evaluates performance and adjusts weights accordingly. Easy access to one’s own performance data also makes it easier to track that progress and stay motivated.

Though it’s too soon to tell if mirror gyms will be the trend of the late 2010s to 2020s, Behar explained that having a screen in the home can become the basis for more than just fitness, such as shopping or telemedicine.

2 . Playing tennis regularly could help keep people off death, but football, rugby and running may not help people to live longer, a study suggests.

A study followed more than 80,000 people for an average of nine years to find out if certain sports protected them against early death. It found that people who played racket sports regularly were the least likely to die over the study period, reducing their individual risk by 47 percent compared with people who did no exercise. Swimmers also reduced their chance of death by 28 percent, aerobics (有氧运动) fans by 27 percent and cyclists by 15 percent. Yet running appeared to have no impact at all on dying early, and neither did playing football or rugby.

Scientists say the difference may lie in the social aspect which goes alongside sports like tennis and squash (壁球), which often involve clubs and organized activities outside of the game. It means that people often have larger social net-works and tend to keep up activities into later life, both of which are proven to be good for health.

In contrast, people who play team sports often do not move onto a new sport once their teams break up for family, or injury reasons. They become watchers rather than participants in their chosen activity.

The researchers found that playing racket sports was associated with a 56 percent lower risk from heart death. Similarly, swimmers lowered their heart disease or stroke risk by 41 percent, and people who took part in activities like aerobics, dance or gymnastics lowered their risk by 36 percent. But again running, football and rugby had no significant impact on heart deaths.

However, other experts argue that this study must not be misinterpreted as showing that running and football do not protect against heart disease. In this study both runners and footballers had a lower rate of death from heart disease.

3. What is considered more important to people's health?

A．Social networks.	B．Staying at home.
C．Physical examinations.	D．Setting up families.

4. What is the main idea of the text?

A．Thousands of people participated in a 9-year research.

B．Study finds playing tennis helps people live longer.

C．It is wrong to say running has no impact on heart disease.

D．There are differences between racket sports and team games.
