Humans are the only creature that gets around by standing up and putting one foot in front of the other. Our ability to walk upright has allowed humankind to travel great distances and survive changing climates, environments and landscapes.

Countless scientific studies have found that walking is really good for us and this simple act can provide a number of healthimplications, which help people live longer. In fact, a walking routine, if done properly, might be the only exercise people need.

How much walking should one aim for? You’ve likely heard we need 10,000 steps a day. That’s about 5 miles. But contrary to popular belief, this recommendation doesn’t come from science. Instead, itis from a 1960s advertising campaign to promote a pedometer (计步器) in Japan. Perhaps because it’s a round number and easy to remember, it stuck.

Since the 1960s, researchers have studied the 10,000-steps-a-day standard and have turned up mixed results. Although 10,000 steps is certainly a healthy and worthwhile goal, it’s not fit for all.

For instance, a recent Harvard University study involving more than 16,000 senior women found that those who got at least 4,400 steps a day greatly reduced their risk of dying early when compared with less active women. The study also noted that these benefits continued up to 7,500 steps. This 7,500 mark isn’t surprising: It’s similar to common public health recommendations, such as the Centers for Disease Control and Prevention’s recommendation of 150 minutes of moderate (适度的) physical activity a week for adults.

4. What does the underlined word “implications” in Paragraph 2 refer to?

A. Benefits

B. Problems.

C. Habits.

D. Manners.

5. Where does the 10,000-steps-a-day standard come from?

A. A Harvard University study.

B. Science research on health.

C. A pedometer advertisement.

D. Public health recommendation.

6. What can we know from the last paragraph?

A. 7,500-steps-a-day standard is the best choice for all.

B. More than 16,000 old people were involved in the study.
