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（隔離）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

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）學過單擺的周期公式以后，物理興趣小組的同學們對鐘擺產(chǎn)生了興趣，老師建議他們先研究用厚度和質(zhì)量分布均勻的方木塊（如一把米尺）做成擺（這種擺被稱為復擺），如圖所示。讓其在豎直平面內(nèi)做小角度擺動，C點為重心，板長為L，周期用T表示。
甲同學猜想：復擺的周期應(yīng)該與板的質(zhì)量有關(guān)。
乙同學猜想：復擺的擺長應(yīng)該是懸點到重心的距離L/2。
丙同學猜想：復擺的擺長應(yīng)該大于L/2。理由是：若OC段看成細線，線栓在C處，C點以下部分的中心離O點的距離顯然大于L/2
為了研究以上猜想是否正確，同時進行了下面的實驗探索；
（1）把兩個相同的木板完全重疊在一起，用透明膠（質(zhì)量不計）粘好，測量其擺動周期，發(fā)現(xiàn)與單個木板擺動時的周期相同，重做多次仍有這樣的特點。則證明了甲同學的猜想是
的（選填“正確”或“錯誤”）。
（2）用T0表示板長為L的復擺（也稱擺長為L/2的單擺）的周期計算值（
），
用T表示板長為L復擺的實際周期測量值。計算與測量的數(shù)據(jù)如下表：
