3 . Taking exercise can be boring. The good news is that there are some tips which we can apply to our everyday fitness routines

•Have an objective.

When we’re playing a game, there’s always an objective. It helps us focus on the task at hand and motivates us to keep playing until we win the game. Exercise should be no different. Create a clear fitness goal.     1    .

•Add an element of whimsy (奇思妙想)

Some people love video games because there’s a lot of unexpectedness and surprise.     2    . Take photos of at least 5 different flowers on a neighborhood walk. Ride a bike from one friend’s house to another.

•    3    

In a study, a team of researchers challenged 602 overweight workers from a single company to take part in a step-tracking challenge. The group asked to compete against other workers ended up walking more steps than any other groups in the study. If we’re seeking a similar motivation, look into fitness programs that encourage friendly competition.

•Team up with others.

    4    . In that same study, another group of workers was asked to divide into teams of three. Each day, one member of the group was selected to represent the entire team with his/her individual step count of the day. This approach encouraged each member of the group to try to achieve the day’s step goal.     5    . We can try to be energetic by working towards an exercise goal together with other people.

7 . If you want to improve your fitness, walking is a great choice.     1     Here are a few tricks that may help you increase your walking stamina (耐力).

Walk for at least 30 minutes 3 to 5 days a week.

    2     But remember—don’t sweat it if you can’t walk this long at the beginning. Over time, your body will get used to a certain level of activity, and that makes it easier for you to walk longer.

    3    

If you only have a short period of time to walk, add force to work on your stamina. You can simply put a few books or solid objects in a backpack and carry that. Keep track of the amount of weight you’re carrying so you can increase it gradually.

Find ways to include walking in your regular routine.

Figure out how you can introduce more walking into your daily routine. For example, you might try using the stairs instead of the elevator.     4    

Download a step-tracking or general fitness app.

A fitness app allows you to set goals for yourself to stay active and increase your walking stamina over time.     5     These devices often measure the distance you’ve walked and include information about your heart rate and calories burned.

8 . 听下面一段独白，回答以下小题。

10 . The rate of childhood obesity in the U. S. has tripled over the past 50 years. The American Academy of Pediatrics (AAP) made waves this year by recommending that doctors put obese kids as young as two years old on intensive, family-oriented lifestyle and behavior plans. It also suggested prescribing weight-loss drugs to children l2 and older and surgery to teens 13 and older. This advice reflects the organization’s adoption of a more active position on childhood obesity.

Yet the lifestyle programs the AAP recommends are expensive, inaccessible to most children and hard to maintain. Few weight-loss drugs have been approved for children. And surgery has potential risks and few long-term safety data. Furthermore, it’s not clear whether interventions in youngsters help to improve health or merely add to the psychological burden overweight kids face from the society.

Rather than paying close attention to numbers on a scale, the U. S. and countries with similar trends should focus on an underlying truth: we need to invest in more and safer places for children to play where they can move and run around, climb and jump, ride and skate.

Why is it so hard to get kids moving? Experts blame the problem on the privatization of sports — as public investment in school-based athletics dwindles, expensive private leagues have grown, leaving many kids out. In addition to fewer opportunities at school, researchers cite increased screen time and a lack of safe places for them to play outside the home. New York City, for example, had 2,067 public playgrounds as of 2019 — a very small amount for its large population. In Los Angeles in 2015, only 33 percent of youths lived within walking distance of a park.

Kids everywhere need more places to play. Public funding to build and keep up these areas is crucial, but other options such as shared-use agreements can make unused spaces available to the public. These opportunities aren’t primarily about changing children’s waistlines — they’re how we keep childhood healthy and fun.
