1、Migrant (移民的) WorkersIn the past twenty years, there has been an increasing tendency for workers to move from one country to another. While some countries have restricted most jobs to local people, others have attracted and welcomed migrant workers. This is particularly the case in the Middle East, ______ increased oil incomes have enabled many countries to call in outsiders to improve local facilities. Thus the Middle East has attracted oil workers from the USA and Europe. It has brought in workers from many countries, including South Korea and Japan.In view of the difficult living and working conditions in the Middle East, it is not surprising that the pay is high to attract suitable workers. Many engineers and technicians can earn at least twice as much money in the Middle East as they can in their own country, and this is a major attraction .Sometimes a disadvantage has a compensating (补偿的) advantage. For example, the difficult living conditions often lead to increased friendship when workers have to depend on each other for safety and comfort. In a similar way, many migrant workers can save large sums of money partly because of the lack of entertainment facilities. The work is often complex and full of problems but this merely presents challenge to engineers who prefer to find solutions to problems rather than do routine work in their home country.One major problem which affects migrant workers in the Middle East is that their jobs are temporary ones. They are nearly always on contract, so it is not easy for them to plan ahead with great confidence. This is to be expected since no country welcomes a large number of foreign workers as permanent residents. In any case, migrant workers accept this disadvantage, along with others, because of the considerable financial benefits which they receive.【单选题】

3、Ants as a Barometer of Ecological ChangeAt picnics, ants are pests. But they have their uses. In industries such as training, farming and forestry, they can help gauge the health of the environment by just crawling around and being antsy.It has been recognized for decades that ants-which are highly sensitive to ecological change can provide a near-perfect barometer of the state of an ecosystem. Only certain species, for instance, will continue to thrive at a forest site that has been cleared of trees. _____. And still others will move in and take up residence.By looking at which species populate a deforested area, scientists can determine how "stressed" the land is. They do this by sorting the ants, counting their numbers and comparing the results with those of earlier surveys. . Ants are used simply because they are so common and comprise so many species.Where mine sites are being restored, for example, some ant species will recognize the stripped land more quickly than others. This allowed scientists to gauge the pace and progress of the ecological recovery. Australian mining company Capricorn Coal Management has been successfully using ant surveys for years to determine the rate of recovery of land that it is replanting near its German Creek mine in Queensland.Ant surveys also have been used with mine-site recovery projects in Africa and Brazil, where warm climates encourage dense and diverse ant populations. "We found it worked extremely well there," says Jonathan Majer, a professor of environmental biology. Yet the surveys are perfectly suited to climates throughout Asia, he says, because ants are so common throughout the region. As Majer puts it: "That\'s the great thing about ants. "Ant surveys are so highly-regarded as ecological indicators that governments worldwide accept their results when assessing the environmental impact of mining and tree harvesting. Yet in other businesses, such as farming and property development, ant surveys aren\'t used widely.Why not? Because many companies can\'t afford the expense or the laboratory time needed to sift results for a comprehensive survey. The cost stems, also, from the scarcity of ant specialists. Employing those people are expensive. 【单选题】

A.This allowed scientists to gauge the pace and progress of the ecological recovery.

B.Yet in other businesses, such as farming and property development, ant surveys aren\'t used widely.

C.Employing those people are expensive.

D.They do this by sorting the ants, counting their numbers and comparing the results with those of earlier surveys.

E.The evolution of ant species may have a strong impact on our ecosystem.

F.Others will die out for lack of food.

正确答案:F

答案解析:第46题前面的句子有certain species，后面的句子有still others，这一定是英语中“some/certain. …. others. …still others”的固定结构。仅从这一点判断，F是答案。

4、Travel Across AfricaFor six hours we shot through the barren (荒芜的) landscape of the Karoo desert in South Africa. Just rocks and sand and baking sun. Knowing our journey was ending, Daniel and I just wanted to remember all we had seen and done. He used a camera. I used words. I had already finished three notebooks and was into the fourth, a beautiful leather notebook I\'d bought in a market in Mozambique.Southern Africa was full of stories and visions. We were almost drunk on sensations. The roaring (咆哮) of the water at Victoria Falls, the impossible silence of the Okavango Delta in Botswana.And then the other things, dogs in the streets, whole families in Soweto livng in one room, a kilometre from clean water.As we drove towards the setting sun, a quietness fell over us. The road was empty and we hadn\'t seen another car for hours. And as I drove, something caught my eye. Something moved close enough to touch them, to smell their hot breath. I didn\'t know how long they had been there next to us.I shouted to Dan: "Look!" But he was in a deep sleep, his camera lying useless by his feet. They raced the car for a few seconds, then disappeared far behind us, a memory of heroic forms in the red landscape. When Daniel woke up an hour later I told him what had happened."Wild horses?" he said. "Why didn\'t you wake me up, Sophia?""I tried, but they were gone after a few seconds.""Are you sure you didn\'t dream it?""You were the one who was sleeping!""Typical," he said, "The best photos are the ones we never take."We checked into a dusty hotel and slept the sleep of the dead.Daniel and Sophia drove slowly through the barren desert.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:B

答案解析:本题较难，有相当数量考生做错了。本题的关键词和信号词是shot through，和barren，好多考生没有认真体会shoot的引申意思，shoot除了有“射击，拍摄”等意思外，还有一个引申意思“飞驰，飞快移动”，该题的一个出题点是确认代词we在文章中的指代意义，另一个出题点是理解单词shot在文章中的意义。考生要注意重点研究。
