Fifty volunteers were alphabetically divided into two equal groups, Group A to participate in a 7 week exercise program, and Group B to avoid deliberate exercise of any sort during those 7 weeks. On the day before the exercise program began, all 50 men participated in a step-test. This consisted of stepping up and down on a 16-inch bench at 30 steps a minute for 5 minutes. One minute after completion of the step-test, the pulse rate of each subject was taken and recorded. This served as the protest for the experiment. For the next 7 weeks, subjects in the experiment group (Group A) rode an exercycle (a motor-driven bicycle-type exercise machine) for 15 minutes each day. The exercise schedule called for riders to ride relaxed during the first day’s ride, merely holding on to the handle bars and foot pedals as the machine moved. Then, for the next 3 days, they rode relaxed for 50 seconds of each minute, and pushed, pulled, and pedaled actively for 10 seconds of each minute. The ratio of active riding was increased every few days, so that by the third week it was half of each minute, and by the seventh week the riders were performing 15 solid minutes of active riding.
At the end of the 7 weeks, the step-test was again given to both groups of subjects, and their pulses taken. The post-exercise pulse rates of subjects in the experimental group were found to have decreased an average of 30 heart beats per minute, with the lowest decrease 28 and the highest decrease 46. The pulse rates of subjects in the control group remained the same or changed no more than 4 beats, with an average difference between the initial and final tests of zero.

37. When were pulse rates taken?
38. The exercise schedule was planned so that the amount of active riding ______.

36.【选项释义】
The step-test was given ______. 台阶测试______。
A. after each exercise period A. 在每次运动后进行
B. at the beginning and at the end of the seven-week period B. 在七周期间的开始和结束进行
C. only once, at the beginning of the seven-week period C. 只有一次，在七周期间的开始进行
D. twice to the men in Group A and once to the men in Group B D. 给A组男子两次，B组男子一次
【考查点】事实细节题
【解题思路】文章第一段提到：On the day before the exercise program began, all 50 men participated in a step-test.（在锻炼项目开始的前一天，所有50名男子都参加了一次台阶测试）和第二段的首句At the end of the 7 weeks, the step-test was again given to both groups of subjects, and their pulses taken.（在7周结束时，再次对两组受试者进行了台阶测试，并记录了他们的脉搏）可知B选项“在七周的开始和结束时”符合题意。
【干扰项排除】A、C、D选项根据解析可知，属于曲解原文。
37.【选项释义】
When were pulse rates taken? 什么时候测量脉搏率？
A. After every exercise period. A. 每次运动之后。
B. Every day. B. 每一天。
C. After the step-tests. C. 台阶测试后。
D. Every time the ration of active riding was increased. D. 每次主动骑乘的比例增加的时候。
【考查点】事实细节题
【解题思路】文章第一段提到：One minute after completion of the step-test, the pulse rate of each subject was taken and recorded.（在台阶测试完成后1分钟，记录每一位受试者的脉搏率）可知选C。
【干扰项排除】A、B、D选项在文中没有提及，属于无中生有。
38.【选项释义】
The exercise schedule was planned so that the amount of active riding ______. 运动时间表的制定是为了保证活动骑行的量______。
A. increased every few days A. 每隔几天就增加一次
B. varied from day to day B. 每天都变化
C. increased until the third week and then was kept constant C. 增加到第三周，然后保持不变
D. increased every exercise period D. 每个运动周期增加
【考查点】事实细节题
【解题思路】由文章第一段最后一句中的The ratio of active riding was increased every few days（活动骑行的比率每隔几天增加一次）可知选A。
【干扰项排除】B、C、D选项在文中没有提及，属于无中生有。
39.【选项释义】
What did Group A do in their program? A组在他们的项目中做了什么？
A. They stepped up and down on a bench each day. A. 他们每天在长凳上上下踏步。
B. They pushed and pulled on exercise handles every day. B. 他们每天推拉运动手柄。
C. They rode on an exercise every day. C. 他们每天练习骑行。
D. They refrained from any exercise. D. 他们不做任何运动。
【考查点】事实细节题
【解题思路】文章第一段提到：For the next 7 weeks, subjects in the experiment group (Group A) rode an exercycle for 15 minutes each day.（在接下来的7周中，A组实验者每天骑15分钟健身脚踏车）可知选C。
【干扰项排除】
A选项是运动计划开始的前一天做的台阶测试的内容，属于张冠李戴；
B选项是计划开始的第一天做的事情，属于张冠李戴；
D选项是B组的计划，属于张冠李戴。
40.【选项释义】
The post-exercise pulse rates of Group B were found on the average to have ______. B组运动后脉搏率平均为______。
A. not changed A. 没有改变
B. gone down 28 beats per minute B. 每分钟下降28次
C. gone down 30 beats per minute C. 每分钟下降30次
D. gone down 4 beats per minute D. 每分钟下降4次
【考查点】事实细节题
【解题思路】由文章第一段中的Group B to avoid deliberate exercise of any sort during those 7 weeks（B组应避免在这7周内刻意进行任何形式的锻炼）和第二段中的The pulse rates of subjects in the control group remained the same or changed no more than 4 beats, with an average difference between the initial and final tests of zero.（对照组受试者的脉搏率保持不变或变化不超过4次，初始测试和最终测试的平均差异为零。）可知B组为对照组，他们的脉搏率没有改变，因此选A。
【干扰项排除】
B、C选项是A组的脉搏率，属于张冠李戴；
D选项，根据解析可知4次是脉搏率的最大变化量，属于偷换概念。
