问题 With but protection
A. It usually gives inadequate (62)______from the weather
B. not only in some developing countries where bicycles are major means of people and goods, (63)______in a few richer towns such as Amsterdam in Holland and Cambridge in England
C. they might be movements associated (64)______work
    There is a range of activities which require movements of about one to four or five miles. These might be leisure activities, such as moving from home to swimming pool, tennis club, the theater or other cultural centers, or to a secondary or more advanced school, or t (65)______ and shopping in the central areas of cities. The use of cars capable of carrying five people at 80 mph for satisfying these needs is wasteful of space and most productive of disturbance to other road users.
    The use of the bicycle, or some more modern derivative of it, is probably worth more consideration than has recently been given to it. The bicycle itself is a remarkably efficient and simple device for using human muscular energy for transportation. In pure energy terms, it is four to five times as efficient as walking, even though human walking itself is twice as efficient as the movement of effective animals such as dogs or gulls. It is still widely used, (66)______.
     (67)______, is not very suitable for carrying goods, and demands considerable muscular work to make progress against wind or uphill. It also offers its rider no protection against collisions with other vehicles. All these difficulties could, however, be greatly eliminated, if not removed, with relatively small changes in design. The whole machine could be enclosed in a plastic bubble which would provide some protection in case of accidents. It would be easy to add a small petrol or electric motor. A wide variety of designs would be possible. As in rowing, we might employ the power of the arms or the general body musculature, as well as those of the legs; more muscular exercise would be good for the health of many people in cities, and a wide use of bicycle like muscle-powered vehicles would be a useful way to ensure this. It could also provide ample opportunities for showing off by the young and vigorous.

选项

答案C

解析 空格前一句的意思为:这些运动可能是些休闲活动,比如从家到游泳池、网球俱乐部、剧院或其他的文化中心,或者是要去一家中学或大学。空格后一句的意思为:开一辆时速80英里、能载5人的汽车去满足这些需要是对空间的浪费,而且会给其他的行车者带来不少麻烦。所以,C项“可能与去市中心工作和购物活动有关”符合题意。所以,答案是C。
