There are a lot of kids who know everything about computers—how to build them, how to take them apart, and how to write programs for games. So if you ask _____3_____ them to explain about the principles of physics that have gone into creating the _____4_____ computer, you don?t have faintest idea. _____5_____
The failure to understand science leads to such things like the neglect of human _____6_____ creative power. It also takes rise to blurring of the distinction between ____7____science and technology. Lots of people don?t differ between the two. Science ____8____ new knowledge that can be applied or not, and technology is the application of is the production of knowledge to the production of some products, machinery or the like. The two are really different, and people who have the faculty for one very seldom have a faculty for the others. _____9_____
Science in itself is harmless, more or less. But as soon as it can provide technology, it?s not necessarily harmful. No society has yet learned to forecast the ___10_____ consequences of new technology, which can be enormous.

第3题
指纹。 这项技术将一束密集的X光对准留有指纹的物体表面,并根据扫描结果创建出计算机图像。
传统的方法是通过常规光线使指纹显示出来,而且要借助粉末等物质,这会改变指纹保存状况。而该新方法使用了一种“微X射线束荧光技术”,可以探测到指纹携带的化学成分,却不会改变指纹的保存状态。
该实验室的一位科学家瓦希德·马吉德表示,对那些大实验室来说,这是获取用其他方法看不到的印迹的最好方法。
马吉德说:“这项技术填补了一项空缺。如果没有这项技术,某些印迹就会变得毫无意义。比如说,如果是深色表面上的指纹,普通技术确实无法精确地探测到它们;如果是青少年或小孩的指纹,他们的指尖留下的化学成分(和成人)是不同的,而且这些指纹附着在物体表面的时间并不久,因此不适宜使用传统的分析方法。”
豪夫里洛说:“这是清晰显示指纹的一种新途径。我们查找印迹时不再只观察手指分泌的油脂和残留有机物,而是专注于其背后隐藏的特殊化学成分。”
该实验室发明的这种新型指纹探测法的创新之处在于它包含了计算机软件技术和机器操作方法。但是这一技术也并非众人皆宜。豪夫里洛笑着说:“我们已经收到了一些负面评论。一位批评者对我们说它压根不实用。但我们工作的目标是证明这种技术是切实可行的。”
第4题
very cold conditions it becomes a solid called ice and that when heating on a fire it becomes a vapor called steam. __2__ However, water, they would say, is a liquid. We have learned that water consists of molecules composed with two atoms of hydrogen __3__ and one atom of oxygen, which we describe by the formula H2O. This is equally true of the solid called ice and the gas called steam. Chemically there is no difference between the gas, the liquid, and the solid, all of which is made up of molecules with the formula H2O. __4__ This is true of other chemical substances; most of them can exist as gases or as liquids or as solids. We may normally think of iron as a solid, but if we will heat it in a furnace, it will melt and become a __5__ liquid, and at very high temperatures it will become a gas. Nothing very permanent occurs when a gas changes into a liquid or a solid. Everyone knows that ice, which has been made by freezing water, can be melted again by warmed and that steam can be condensed __6__ on a cold surface to become liquid water. In fact, it is only because water is so a familiar substance that different names are used for __7__ the solid, liquid and gas. Most substances are only familiar with __8__ us in one state, because the temperatures requiring to turn them __9__ into gases are very high, or the temperatures necessary to turn them into solids are so low. Water is an exception in this respect, which is another reason why its three states have given three different names. __10__

p being strucked by the __1__ appearance of the women taking part. Their hair styles and make-up look date; their skirts look either too long or too __2__ short; their general appearance is, in fact, slightly ludicrous.
The men taking part, on other hand, are clearly recognizable. __3__ There is nothing about their appearance to suggest that they belong to an entire different age. This illusion is created __4__ by changing fashions. Over the years, the great minority of men __5__ have successfully resisted all attempts to make it change their __6__ style. of dress. The same cannot be said for women. Each year,a fewer so-called top designers in Paris and London lay down __7__ on the law and women around the world run to obey. The __8__ decrees of the designers are unpredictable and dictatorial.Sometime they decide arbitrarily, that skirts will be short and __9__ waists will be height; hips are in and buttons are out. __10__

第8题
few men are secure? The tools of his industry are so common and so cheap that they have almost ceased to have commercial value. He needs no bulky pile of raw material, no elaborate apparatus, no service of men or animals. He is dependent for his occupation upon no one but himself, and nothing outside him that his occupation upon no one but himself, and nothing outside him that maters. He is the sovereign of an empire, self supporting, self-contained. . . No one can deprive him of his stock in trade; no one can force him to exercise his faculty against his will; no one can prevent him exercising it as he chooses. The pen is the great liberator of men and nations. No chains can bind, no poverty can choke, no tariff can restrict the free play of his mind.
(From The Joys of Writing by Winston Churchill)
第9题
nt very few people have reached this level. Moreover, the exercise of choice is in itself tiresome. Except to people with unusual initiative it is positively agreeable to be told what to do at each hour of the day, provided the orders are not too unpleasant. Most of the idle rich suffer unspeakable boredom as the price of their freedom from hard work. At times, they may find relief by hunting big game in Africa, or by flying round the world, but the number of such sensations is limited, especially after youth is past. Accordingly the more intelligent rich men work nearly as hard as if they were poor, while rich women for the most part keep themselves busy with innumerable trifles, of whose earthshaking importance they are firmly persuaded.
