B: 阅读下面短文，从每题所给的三个选项（A、B和C）中，选出最佳选项。
If you’re ready to add more physical activity(体育运动) to your life, here are some tips(建议).
Make physical activity part of your routine, like brushing your teeth or going to work. Try biking to work at least once a week, using the stairs more often, or walking to some places near home. But talk to your doctor before you start an exercise routine, especially if you haven’t been very active or have health problems.
Walking is one of the best fitness(健康) activities. To keep up a routine, you can walk with family members, friends or pets. Count your steps with a step counter(计数器). You can buy one at a sporting goods store. If you don’t have time for one 30-minute walk, break it into three 10-minute walks.
Find an activity that you enjoy, and stay with it. Change it with other activities so you don’t get bored. For example, walk three days a week, and swim or bike on the other days. Join a volleyball or basketball club for fun and exercise. By finding more activities you enjoy, you’ll have a greater chance for success.
