I am one of the many city people who are always saying that given the choice we would prefer to live in the country away from the dirt and noise of a large city. I have managed to convince myself that if it weren’t for my job I would immediately head out for the open spaces and go back to nature in some sleepy village buried in the country. But how realistic is the dream?
Cities can be frightening places. The majority of the population live in massive tower blocks, noisy, dirty and impersonal. The sense of belonging to a community tends to disappear when you live fifteen floors up. All you can see from your window is sky, or other blocks of fiats.
Strangely enough, whereas in the past the inhabitants of one street all knew each other, nowadays people on the same floor in tower blocks don’t even say hello to each other.
Country life, on the other hand, differs from this kind of isolated（隔离）existence because a sense of community generally ties the inhabitants of small villages together. But country life has disadvantages too. It is true that you are cut off from the exciting and important events that take place in cities. There’s little possibility of going to a new show or the latest movie. Shopping becomes a major problem, and for anything slightly out of the ordinary you have to go on an expedition to the nearest large town. The city-people who leave for the country are often oppressed by a sense of unbearable stillness and quietness.
What , then , of my dreams of leaning on a cottage gate and murmuring “morning” to the locals as they pass by? I’m eager for the idea, but you see there’s my cat, Toby. I’m not at all sure that he would take to all that fresh air and exercise in the long grass. I mean, can you see him mixing with all those hearty males down the farm? No, he would rather have the electric fire any evening.
63. We learn from Paragraph I that the writer________.
A. used to live in the country B. used to work in the city
C. works in the city D. lives in the country
64. In the writer’s opinion , the following may cause city people to be unhappy EXCEPT_______.
A. a strong sense of fear B. a lack of communication
C. housing conditions D. a sense of isolation
65. The text implies that it is not easy to buy ______ in the country.
A. agricultural produce B. fresh fruits C. fresh vegetables D. designed clothes
66. The passage manly talks about_______
A. the advantages of living in cities
B. the difference between living in cities and villages
C. most people prefer to live in cities D. the advantages of living in villages

13、（6分）学过单摆的周期公式以后，物理兴趣小组的同学们对钟摆产生了兴趣，老师建议他们先研究用厚度和质量分布均匀的方木块（如一把米尺）做成摆（这种摆被称为复摆），如图所示。让其在竖直平面内做小角度摆动，C点为重心，板长为L，周期用T表示。
甲同学猜想：复摆的周期应该与板的质量有关。
乙同学猜想：复摆的摆长应该是悬点到重心的距离L/2。
丙同学猜想：复摆的摆长应该大于L/2。理由是：若OC段看成细线，线栓在C处，C点以下部分的中心离O点的距离显然大于L/2
为了研究以上猜想是否正确，同时进行了下面的实验探索；
（1）把两个相同的木板完全重叠在一起，用透明胶（质量不计）粘好，测量其摆动周期，发现与单个木板摆动时的周期相同，重做多次仍有这样的特点。则证明了甲同学的猜想是
的（选填“正确”或“错误”）。
（2）用T0表示板长为L的复摆（也称摆长为L/2的单摆）的周期计算值（
），
用T表示板长为L复摆的实际周期测量值。计算与测量的数据如下表：
