Taking your pulse during physical activity allows you to measure how hard you are exercising． You should exercise to stay within your target heart range．
• Use your index finger （食指） and middle finger． Don't use your thumb （拇指） -it has a pulse of its own．
• Place these two fingers on your wrist， just below the base of the thumb．
• Count the number of beats （pulses） for 15 seconds．
• Take this number and multiply by 4 to find your heart rate in beats per minute． For example， if you count 25 beats， 25 x 4 = 100 beats per minute．
Increasing your heart rate is a key part of exercise， but it is important that your heart rate is not too high or too low． If you are a beginner， you should also be able to breathe comfortably while exercising． This will ensure that you are exercising at a level that is safe and effective for your body．
The chart below illustrates target heart rate ranges for exercise based on the maximal heart rate for selected ages． Here are the steps for using the chart：
Measure your exercise heart rate in beats per minute （BPM）．
Look at the chart．
- Find your age． If your age falls between the ages listed， round up to the next older age listed．
- Compare your heart rate to the target exercise range．
• If you are doing moderate exercise， your heart rate should be closer to the 50% range．
• If you are doing vigorous exercise， your heart rate should be closer to the 85% range．
• Try to stay in the 50-85% range when exercising by increasing or decreasing exercise intensity．
（1）Which of the following is TRUE？ ____
A． Exercise intensity can be reflected by a person's heart rate．
B． The faster your heart rate is， the more effective the exercise is．
C． Vigorous exercise will definitely present a threat to people's safety．
D． The target exercise heart rate range for a 45-year-old is 90-149 BPM．
（2）A 34-year-old man is running and the number of pulses he takes for 15 seconds is 40．His fitness coach had better tell him ____ ．
A． "You are doing fine．"
B． "You can run faster．"
C． "You should slow down a bit．"
D． "You should drink some water．"
（3）What is the purpose of this passage？ ____
A． To advise people to form a habit of taking their pulses while exercising．
B． To inform people of the target heart rate zone for those aged 60 and under．
C． To tell people the importance of maintaining moderate amount of exercise．
D． To show people how to measure heart rate to keep proper exercise intensity．

题目解答
答案
（1）A． 细节理解题．根据第一段的内容"Taking your pulse during physical activity allows you to measure how hard you are exercising． You should exercise to stay within your target heart range．在体育活动中测量脉搏可以测量你的运动强度．你应该运动以保持在你的目标心脏范围内．"及表格上的数据可知，一个人的心率可以反映运动强度．故选A．
（2）C． 细节理解题．根据表格中给的测量心率的方法可知，此人的每分钟的心率是40*4=160 ，结合数据表格，年龄34，从35岁那一栏可知，大于百分之85，根据图表说明可知，属于剧烈运动，因此他的健康教练应该告诉他放慢点．故选C．
（3）D． 目的意图题．文章通过告诉读者如何给自己把脉以及用两个表格向人们展示如何测量心率以保持适当的运动强度．由此可知，文章的目的是向人们展示如何测量心率以保持适当的运动强度．故选D．
（2）C． 细节理解题．根据表格中给的测量心率的方法可知，此人的每分钟的心率是40*4=160 ，结合数据表格，年龄34，从35岁那一栏可知，大于百分之85，根据图表说明可知，属于剧烈运动，因此他的健康教练应该告诉他放慢点．故选C．
（3）D． 目的意图题．文章通过告诉读者如何给自己把脉以及用两个表格向人们展示如何测量心率以保持适当的运动强度．由此可知，文章的目的是向人们展示如何测量心率以保持适当的运动强度．故选D．
