听力原文： Lecturer: In the last lecture, we looked at the adverse effects of desert dust on global climate. Today we're going to examine more closely what causes dust storms and what other effects they can have. As you know, dust storms have always been a feature of desert climates, but what we want to focus on today is the extent to which human activity is causing them. And it is this trend that I want to look at, because it has wide-ranging implications. So, what are these human activities？ Well, there are two main types that affect the wind erosion process, and thus the frequency of dust storms. There are activities that break up naturally wind-resistant surfaces such as off-road vehicle use and construction and there are those that remove protective vegetation cover from soils, for example, mainly farming and drainage. In many cases the two effects occur simultaneously which adds to the problem. Let's look at some real examples and see what I'm talking about. Perhaps the best-known example of agricultural impact on desert dust is the creation of the USA's 'dust bowl' in the 1930s. The dramatic rise in the number of dust storms during the latter part of that decade was the result of farmers' mismanaging their land. In fact, choking dust storms became so commonplace that the decade became known as the 'Dirty Thirties'. Researchers observed a similar, but more prolonged, increase in dustiness in West Africa between the 1960s and the 1980s when the frequency of the storms rose to 80 a year and the dust was so thick that visibility was reduced to 1,000 metres. This was a hazard to pilots and road users. In places like Arizona, the most dangerous dust clouds are those generated by dry thunderstorms. Here, this type of storm is so common that the problem inspired officials to develop an alert system to warn people of oncoming thunderstorms. When this dust is deposited it causes all sorts of problems for machine operators. It can penetrate the smallest nooks and crannies and play havoc with the way things operate because most of the dust is made up of quartz which is very hard. Another example - the concentration of dust originating from the Sahara has risen steadily since the mid-1960s. This increase in wind erosion has coincided with a prolonged drought, which has gripped the Sahara's southern fringe. Drought is commonly associated with an increase in dust-raising activity but it's actually caused by low rainfall which results in vegetation dying off. One of the foremost examples of modern human-induced environmental degradation is the drying up of the Aral Sea in Central Asia. Its ecological demise dates from the 1950s when intensive irrigation began in the then Central Asian republics of the USSR. This produced a dramatic decline in the volume of water entering the sea from its two major tributaries. In 1960, the Aral Sea was the fourth-largest lake in the world, but since that time it has lost two-thirds of its volume, its surface area has halved and its water level has dropped by more than 216 metres. A knock-on effect of this ecological disaster has been the release of significant new sources of wind-blown material, as the water level has dropped. And the problems don't stop there. The salinity of the lake has increased so that it is now virtually the same as sea water. This means that the material that is blown from the dry bed of the Aral Sea is highly saline. Scientists believe it is adversely affecting crops around the sea because salts are toxic to plants. This shows that dust storms have numerous consequences beyond their effects on climate, both for the workings of environmental systems and for people living in drylands ...

Among isolated peoples ,who are not often reached by traders from outside ,commerce usually means barter ,which is a direct exchange of goods .Perhaps it is fish for vegetables or meat for baskets .For this kind of simple trading, money is not needed ,but there is often something that everyone wants ,such as salt to flavor food, shells for necklaces ,or iron and copper to make into tools. These things — salt ,shells or metals — are still used as money in out-of-the-way parts of the world today. Salt may seem rather a strange material to use as money ,but in countries where the food of the people is mainly vegetables ,it is often an absolute necessity .Cakes of salt ,stamped to show their value ,were used as money in Tibet until recent times, and they can still buy goods in parts of Africa. Cowrie seashells have been used as money at some time or another over the greater part of the Old World. These were collected mainly from the beaches of the Maldive Islands in the Indian Ocean ,and were traded to India and China. In Africa ,cowries were traded right across the continent from East to West .Four or five thousand went for one Maria Theresa dollar ,an Australian silver coin which was once accepted as currency (货币) in many parts of Africa. Metal was used as money in many parts of the world .Iron ,in lumps ,bars or rings is still used in many countries instead of money .It can either be exchanged for goods ,or made into tools or weapons. The early money of China ,apart from shells ,was of bronze ,often in flat ,round pieces with a hole in the middle ,called ‘ cash ’.The earliest of these are between three thousand and four thousand years old — older than the earliest coins of the eastern Mediterranean. Nowadays ,coins and notes have supplanted nearly all the more picturesque forms of money ,and although in one or two of the more remote countries people still store it for future use ,primitive money will soon be found only in museums. 1.Nowadays we think of money as() . A.pieces of metal or metallic paper B.made of either metal or paper C.some printed notes and papers D.round and flat sheets of paper 2.In some parts of the world a traveler might go hungry() . A.even if his money was of the local kind B.even if he had no coins or notes C.if he did not know the local rate of exchange D.even if he had plenty of ready money 3.What can we infer from the passage？ A.Isolated peoples exchange goods by means of barter. B.Salt cakes are taking the place of picturesque forms. C.Seashells could be traded with Maria Theresa dollars. D.The Chinese were among the earliest users of metal ‘ cash ’. 4.Primitive types of money will be used (). A.to replace more picturesque forms B.as exhibits to be shown in public C.at local country markets and shops D.as entrance tickets in museums
