试题答案：
C
答案解释：
解题思路： 本题考查非谓语动词的用法。根据题意“这本生物医学书上的绝大多数实验似乎都不难操作”。当非谓语动词与其所修饰的名词之间的关系是被动关系时，如果是指过去发生的动作，则用过去分词作定语；如果是现在正在发生的动作，用现在分词的被动形式作定语；如果指的是一个未来的动作，用不定式的被动形式作定语。题目中experiments和describe之间的关系是被动关系，并且是一般现在时态，故正确答案为C）选项。

“Time,” says the proverb, “is money”. This means that every moment well spent may put some money into our pockets. If our time is usefully employed, it will either turn out some useful important piece of work which will fetch its price in the market, or1. it will add to our experience increase our capacities so as to enable us to earn money when the proper opportunity comes. Our life is nothing more than our time. To kill time is therefore a form of suicide. 2.We are shocked when we think of death, we spare no pains, no trouble, no expense to preserve life. 3.But we are too often indifferent to the loss of an hour or of a day, forgetting that our life is the sum total of the days of the hours we live. Our life is a brief period measuring some seventy or eighty years in all. But nearly one third of this has to be spent in sleep; some years have to be spent over our meals; some in making journeys on lvoyages by sea; some in merry making. Now if all these years were to be deducted(扣除) from the term over which our life extends, we shall find about twenty or thirty years at our disposal for active work. 4.Whoever remembers this can never willingly waste a single moment of his life. All time is precious，but the time of our childhood of our youth is more precious than any other portion of our existence.5.for those are the periods when we can acquire knowledge develop our capacities. If we allow these morning hours of life to slip away, we shall never be able to recover the loss. Just as money laid out at interests doubles trebles itself in time, so the precious hours of childhood youth, if properly used, will yield us incalculable advantages.(20分)

4. 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 had recorded. This served as the pretest for the experiment. For the next 7 weeks, subjects in the experimental 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 were 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.(5分)4.1How many people were in each group?____(1分)A. 100.B. 50.C. 25.
