But not everybody is aware that high cost and easy comfort are merely two of the effects of the vast cooling of American. In fact, air conditioning has substantially altered the country’s character and customs.

　　Many of the byproducts are so conspicuous that they are scarcely noticed. To begin with, air-conditioning transformed the face of America by making possible those glassy, boxy, sealed-in skyscrapers. It has been indispensable, no less, to the functioning of sensitive advanced computers, whose high operating temperatures require that they be constantly cooled. . .

　　It has, at will, forced families into retreating into families with closed doors and shut windows, reducing the interactions of neighborhood life. It is really surprising that the public’s often noted withdrawal into self-pursuit and privacy has coincided with the historic spread of air-conditioning. Though science has little studied how habitual air-conditioning affects mind and body, some medical experts suggest that, like other technical avoidance of natural variations in climate, air-conditioning may damage the human capacity to adapt to stress. If so, air-conditioning is only like many other greatly useful technical developments that liberate man from nature by increasing his productivity and power in some way - while indirectly weakening him in others.

　　答案：

　　1.A)Its excessive use of air-conditiong對應(yīng)原文Today most Americans need to take air-conditioning for granted to homes, offices, factories, theatres, shops, studios, schools, hotels, and restaurants.

　　take sth for granted認為某事理所當然

　　2.B)the reduction of social communications of neighborhood life對應(yīng)原文forced families into retreating into families with closed doors and shut windows, reducing the interactions of neighborhood life

　　neighborhood life社區(qū)生活

　　選項A并未對應(yīng)題干中的According to the author　而是對應(yīng)原文中的some medical experts suggest that

　　3.標準答案是C)brings more benefits than damage to its users，但我認為應(yīng)該選D)does harm as well as good to its users，對應(yīng)原文最后一句If so, air-conditioning is only like many other greatly useful technical developments(positive words)that liberate man from nature by increasing his productivity and power in some way - while indirectly weakening him in others(negative words)，于是does harm as well as good to its users.

　　4.D)Consumers是最精確的。原文直接批判空調(diào)的一句話是forced families into retreating into families with closed doors and shut windows, reducing the interactions of neighborhood life，顯然according to the author，consumers為從空調(diào)中受益最少的。而ABC三個選項，BC可以作為by increasing his productivity的受益者，A的工作性質(zhì)則完全與空調(diào)無關(guān)，ABC甚至也都可以成為D的一種。

　　5.C)Critical對應(yīng)原文It has, at will, forced，聽起來很像批判。

　　at will 隨意　任意

　　Of the thousands of different kinds of animals that exist in the world man has learned to make friends with an enormous number. Some are pets, and offer him companionship; some give protection, and some do hard work which man cannot do for himself. Dogs, which serve man in all three capacities, are found in various breeds in all countries of the world. The Husky can live in the cold polar regions, and the Saluki is at home in the hottest parts of Central Africa. The inhabitants of certain countries are dependent for their very lives on the camel. In the West Indies the little donkey, strong and sure-footed, carrying heavy loads even in mountainous places, is a familiar sight.來源：考試大

　　Trained and tamed for many generations, domestic animals are not accustomed to roaming(到處走動) in search of food and shelter. They look to their masters to provide for their needs, and as long as these are supplied, they are content to do what their masters require.

　　All domestic animals need proper food. It must be suitable for them, sufficient in quantity, fresh and clean. Some people feed a pet dog or cat on odds and ends of table scraps, and then wonder why the animal seems listless(倦怠的) and dull. The quantity of food depends on the size of the animal and the amount of exercise it takes. Overfeeding is as bad as underfeeding. Containers for food and water must be washed regularly if the animal is to maintain good health.

　　Even well cared for animals may sometimes fall ill. If this happens, the wise master seeks the best advice he can get. All sorts of medicines and treatments are available for sick animals, and in some countries organizations exist to provide them free or at a cheap price. Useful, friendly, hardworking animals deserve to have some time, money and attention spent on their health.

　　答案：

　　1.B)Man came to establish a close relationship with a number of animals. 黑體部分為第一段兩個要點，A只包含了一個要點，C只提到了一頭驢。D則完全與第一段無關(guān)。這道選錯了要面壁哦。

　　2.A)refuse to obey its master對應(yīng)原文Some people feed a pet dog or cat on odds and ends of table scraps(即題干中的When an animal is underfed, 所以要在這句話中找答案～), and then wonder why the animal seems listless(倦怠的) and dull. 由于答案比較隱晦, 先保留A, B(直接得病)、C(要求食物)和D(自己覓食)均未從此句中得到絲毫體現(xiàn), 所以A為最接近答案. 因為我家養(yǎng)過狗, 所以比較清楚, refuse to obey its master的一個表現(xiàn)就是listless and dull, 簡單的說, 就是你逗它它沒反應(yīng)。
