About 1.4 billion people around the world do not get enough physical exercise.This number comes 【小题1】the United Nations' World Health Organization(WHO).A new WHO report warns that a lack of exercise 【小题2】(great)increases the risk of health problems.The WHO says the new study is the first【小题3】 (estimate)physical activity trends around the world over time.The report said the levels of physical inactivity are more than two times as high in 【小题4】(wealth)countries as they are in countries where people earn low wages.In richer countries,people are more likely to spend time 【小题5】（sit)in offices.

How much activity should we get?

To stay healthy,the report 【小题6】(suggest)that people do at least 150 minutes of moderate(适中的）physical activity or 75 minutes of intense physical activity every week.If you work in a high-rise office building,take the stairs instead of an elevator.Take more 【小题7】(break)during the work day and move around.If your workplace offers 【小题8】gym,make sure to use it.It also urges governments to provide and care for infrastructure(基础设施），such as better and【小题9】 (safe)roads.This would help support increased walking 【小题10】cycling for transportation,as well as sports and physical recreation.

We’ve all encountered failure. Perhaps, it’s blowing a job interview, failing a final exam, or getting 【小题1】 (reject) from your dream school. Whether we like it or not, failure is part of life. How people respond to these obstacles is 【小题2】 great importance both to their decisions and achievements. But eventually, we’re told, 【小题3】 (overcome) difficult obstacles will make a future success taste so much sweeter. New research, however, may challenge this belief. Findings show that early failures can lead people 【小题4】 (question) how good it would feel to succeed.

A “Growth Mindset” Can Lead to Success

The most successful people are fond of telling us about their passion for their professions. And passion has been believed to be essential to not only their success, but also their happiness.

Unfortunately, 【小题1】 some people have a clear “calling” from a young age, many still leave education without knowing their vocation in life. They may spend their whole life without having ever discovered a career that truly 【小题2】 (interest) them. In the past ten years, the researcher 【小题3】 (demonstrate) that some people tend to see their abilities as “fixed”—they believe that they are either born with a talent for something or they don’t have it completely. What can they do?

Some answers come from the work of Paul O’Keefe. In his mindset theory, the most basic foundation of passion is having an intense interest in 【小题4】 you’re doing. Meanwhile, people also have the capacity to cultivate new interests outside their normal fields. 【小题5】 (consider) arts students looking at a piece about science, or “techy” students reading an article on literary criticism(文学评论). 【小题6】 the students have very little initial curiosity about the subject, with the growth mindset, they will change their ratings of the interest in that new subject after reading the piece.

In addition, a person’s mindset can also determine how long they would be interested in more difficult content and 【小题7】 they would plan to deal with the content or not. In one experiment, after 【小题8】(show) a video about black holes, people had to read a challenging academic paper on the subject. The people with the growth mindset maintained their interest: they were 【小题9】 (willing) to know about the black holes despite the difficulties of grasping the technical material. By contrast, the flame of interest quickly burnt out in those with the fixed mindset. “Within the span of seven minutes they went from saying ‘this is fascinating’ 【小题10】saying ‘no, I’m done,’” says O’Keefe.
