2 . When it comes to being fit and healthy, we're often reminded to aim to walk 10,000 steps per day. This can be a frustrating target to achieve, especially when we're busy with work and other commitments.

The 10,000 steps a day target seems to have come about from a trade name pedometer sold in 1965 by Yamasa Clock in Japan. The device was called "Manpo-kei", which translates to "10,000 steps meter". This was a marketing tool for the device and has seemed to have stuck across the world as the daily step target. It's even included in daily activity targets by popular smart-watches, such as Fitbit.

In ancient Rome, distances were actually measured by counting steps. In fact, the word "mile" originated from the Latin phrase mila passum, which means about 2,000 steps. It's suggested the average person walks about 100 steps per minute，which would mean it would take a little under 20 minutes for the average person to walk a mile. So in order for someone to reach the 10,000-step goal, they would need to walk about five miles a day, nearly two hours of activity.

Researchers have investigated the 10,000 steps a day target. The fact that some studies have shown this step target improves heart health, mental health, and even lowers diabetes (糖尿病) risk, may, to some extent, explain why we have stuck with this number.

But while some research has shown health benefits at 10,000 steps, recent research from Harvard Medical School has shown that, on average, nearly 4,400 steps a day is enough to significantly lower the risk of death in women. This was when compared to only walking around 2,700 steps daily. The more steps people walked, the lower their risk of dying was, before leveling off at around 7,500 steps a day. No additional benefits were seen with more steps. Although it's uncertain whether similar results would be seen in men, it's one example of how moving a little bit more daily can improve health and lower risk of death.

Like many boys, my favorite sport is playing basketball. To be honest, I felt clumsily when I first learned to play it because I wasn’t as energetic as another, and I moved slowly. And I was determined not to left behind. I spent my spare time to practicing it. Gradually, I made progresses. I can’t forget how exciting I was when I scored points for the first time. And I can still remember the joy of victory after win a match. That’s why I fell in love with basketball. Since then, it had become part of my life. It strengthens my body and mind. It also helps me become more confident and strong-willed.

6 . You've probably heard it suggested that you need to move more throughout the day, and as a general rule of thumb, that "more" is often defined as around 10,000 steps. With many Americans tracking their steps via new fitness-tracking wearables, or even just by carrying their phone, more and more people use the 10,000-step rule as their marker for healthy living. Dr. Dreg Hager, professor of computer science at Johns Hopkins, decided to take a closer look at that 10,000-step rule, and he found that using it as a standard may be doing more harm than good for many.

“It turns out that in 1960 in Japan they figured out that the average Japanese man, when he walked 10,000 steps a day burned something like 3,000 calories and that is what they thought the average person should consume so they picked 10,000 steps as a number” Hager said.

According to Hager, asking everyone to shoot for 10,000 steps each day could be harmful to the elderly or those with medical conditions, making it unwise for them to jump into that level of exercise, even if it's walking. The bottom line is that 10,000 steps may be too many for some and too few for others. He also noted that those with shorter legs have an easier time hitting the 10,000-step goal because they have to take more steps than people with longer legs to cover the distance. It seems that 10,000 steps may be suitable for the latter.

A more recent study focused on older women and how many steps can help maintain good health and promote longevity (长寿).The study included nearly 17,000 women with an average age of 72. Researchers found that women who took 4,400 steps per day were about 40% less likely to die during a follow-up period of just over four years: Interestingly, women in the study who walked more than 7,500 steps each day got no extra boost in longevity.

3. Who will probably benefit from 10,000 steps each day according to Hager?

A．Senior citizens.	B．Young short-legged people.
C．Healthy long-legged people	D．Weak individuals.

A．4,400 steps.	B．10,000 steps.
