中国古代的科学著作大多是经验型的总结，而不是理论型的探讨，所记各项发明都是为了解决国家与社会生活中的实际问题，而不是试图在某一研究领域获得重大突破。从研究方法上来说，中国科技重视综合性的整体研究，重视从总体上把握事物，而不是把研究对象从错综复杂的联系中分离出来，独立研究它们的实体和属性，细致探讨它们的奥秘。这使得中国古代的科学技术没有向更高层次发展。（）

A.研究方法的缺陷使中国古代科技长期停滞不前

B.解决实际问题是推动中国古代科技发展的动力

C.中国古代的科学研究关注的重点及其历史背景

D.中国古代的科技水平没有长足进步的根本原因

答案

参考答案：D

解析：

文段意在说明中国古代的科技水平没有长足进步的根本原因在于“中国古代的科学著作大多是经验型的总结，而不是理论型的探讨；研究方法上来说，中国科技重视综合性的整体研究，重视从总体上把握事物，而不是把研究对象从错综复杂的联系中分离出来”。

本题容易误选A项，其实A项错在两个方面：

一是中国古代科技并非停滞不前，而只是没有长足进步；

二是研究方法的缺陷只是没有长足进步的原因之一，而不是全部

问答题

Exercise, everyone advises! But immediately, when you try, you run into trouble. (46)There is so much contradictory, sometimes incorrect advice about exercising that you become confused. Test yourself on the following true false quiz. It will tell you what you need to know.
1. The best way to reduce the mid-section is to do abdominal exercise.
False. Many people believe that when specific muscles are exercised, the fatty tissues in the immediate area are "burned up." (47)The truth-is that exercise burns fat from all over the body and not from one specific area, regardless of the type of exercise. Of course, if you reduce the fat throughout your body, you will certainly see results around your waistline too!
2. To maintain an adequate level of physical fitness, you need to exercise only twice a week.
False. Studies conducted by NASA, the National Aeronautics and Space Administration, show that unexercised muscles lose their strength very quickly. After 48 to 72 hours, you must use the muscles again to reestablish the good physical effect. And what does that mean to you (48) NASA scientists concluded that while daily exercise is most beneficial, three alternating days each week will maintain an adequate level of physical fitness.
3. To lose weight you should always "work up a good sweat" when exercising.
False. Sweating only lowers body temperature to prevent overheating; it does not help you reduce weight. You may weigh less immediately after a workout, but this is due to water loss. Once you replace the liquid, you replace the weight.
4. If your breathing doesn’t return to normal within minutes after you finish exercising, you’ve exercised too much.
True. Five minutes or so after exercising, your breathing should be normal, your heart shouldn’t be pounding, and you shouldn’t be exhausted. (49) Beneficial exercise is not overly difficult, unpleasant, and exhausting; it is moderate, enjoyable, and refreshing.
5. Walking is one of the best exercises.
True. Walking helps circulation of blood throughout the body, and thus has a direct effect or your overall feeling of health.
6. The minimum amount of time you should spend exercising in a day is 20 minutes.
True. There are more than 400 muscles that attach to your skeleton. (50) A good exercise routine should contract and stretch all these muscles, and this simply cannot be done with four or five exercises in five to ten minutes. From experience, I’ve found that about 20 minutes is the minimum amount of time needed for an adequate workout.
