1、Dung to DeathFields across Europe are contaminated with dangerous levels of the antibiotics given to farm animals. The drugs, which are in manure sprayed onto fields as fertilizers, could be getting into our food and water, helping to create a new generation of antibiotic-resistant "superbugs". The warning comes from a researcher in Switzerland who looked at levels of the drugs in farm slurry His findings are particularly shocking because Switzerland is one of the few countries to have banned antibiotics as growth promoters in animal dead.Some 20,000 tons of antibiotics are used in the European Union and the US each year. More than half are given to farm-animals to prevent disease and promote growth. ______Most researchers assumed that humans become infected with the resistant strains by eating contaminated meat. But far more of the drugs end. up in manure than in meat products, says Stephen Mueller of the Swiss Federal Institute for Environmental Science and Technology in Dubendorf. And manure contains especiaily high levels of bugs that are resistant to antibiotics he says.With millions of tons of animals manure spread onto fields of crops such as wheat and barley each year, this pathway seems an equally likely route for spreading resistance, he said. The drugs contaminate the crops, which are then eaten. They could also be leaching into tap water pumped from rocks beneath fertilized fields.Mueller is particularly concerned about a group of antibiotics called sulphonamides. They do not easily degrade or dissolve in water. His analysis found that Swiss farm manure contains a high percentage of sulphonamides; each hectare of field could be contaminated with up to 1 kilogram of the drugs. This concentration is high enough to trigger the development of resistance among bacteria. But vets are not treating the issue seriously. There is growing concern at the extent to which drugs, including antibiotics, are polluting the environment. Many drugs given to humans are also excreted unchanged and are not broken down by conventional sewage treatment.【单选题】

A.They do not easily degrade or dissolve in water.

B.And manure contains especiaily high levels of bugs that are resistant to antibiotics he says.

C.Animal antibiotics is still an area to which insufficient attention has been paid

D.But recent research has found a direct link between the increased use of these farmyard drugs and the appearance of antibiotic-resistant bugs that infect people.

E.His findings are particularly shocking because Switzerland is one of the few countries to have banned antibiotics as growth promoters in animal dead.

F.They could also be leaching into tap water pumped from rocks beneath fertilized fields.

正确答案:D

答案解析:前两句讲的是抗生素在欧洲和美国的大量使用，选项D讲的是由此导致的不良后果，接上去是最合理不过的。But明确地表明了这一转折。

2、AIDSAs a science writer, I don\'t have to wear emotional armor very often. Before I went to Zimbabwe for a visit, I had talked to other reporters who had spent time in Africa. All told me to get prepared for the orphans, many of whom had caught the AIDS virus from their mothers and the strong desire to make everything all right for them. Then again, nothing could have prepared me for the visit to creche(育婴堂) for AIDS orphans in Harare, where one sick, smiling four-year-old boy tried to keep up with the other kids playing ring-around-the-rosy but was so weak he kept falling to the floor, or meeting a 25-year-old unmarried girl who cared for her nephew ______ The boy who called his aunt "Mama" was too weak even to take the piece of banana I offered. Meanwhile photojournalist Karin Retief was visiting a room at the hospice (济贫院) where she had been told a particularly sweet orphan boy stayed. At first she did not see anyone on the bed and was about to say he must be elsewhere, when suddenly she spotted his tiny arm in the air, his body lost in the folds of the bedclothes. Recently Karin wrote to me that she had been able to keep our assignment from taking too great an emotional suffering at the time. " Only when I got back about a week later, could I moum the people I met", she continued. "I sat in church and wanted to ask the priest to pray for the people with AIDS in Zimbabwe and all over the world. Then all the people\'s faces, pain and suffering became so real, I could not get the words out. I broke down and cried and cried for them". 【单选题】

A.where she had been told a particularly sweet orphan boy stayed

B.who had spent time in Africa

C.Only when I got back about a week later

D.even though her only income was from growing and selling a few vegetables at the local market

E.was so weak he kept falling to the floor

F.while we were visiting the orphans

正确答案:D

答案解析:一个未婚女孩照顾她的侄子，尽管她的唯一收入来源是种菜，并在当地市场出售。符合语法要求，意思也完整。因此选D。

正确答案:A

答案解析:选项A中的主语They提示我们应该寻找一个复数的先行词，根据句子的意思：既不衰减又不溶于水，这个They指的不是人而是物，我们在上一句里找到sulphonamides。这个复数形式的名词，从意思上看也正合适。

4、Looking to the FutureWhen a magazine for high-school students asked its readers what life would be like in twenty years, they said: Machines would be run by solar power. Buildings would rotate so they could follow the sun to take maximum advantage of its light and heat. Walls would "radiate light" and "change color with the push of a buttons." Food would be replaced by pills. School would be taught "by electrical impulse while we sleep." Cars would have radar. Does this sound like the year 2000? ______. The future is much too important to simply guess about, the way the high school students did. So experts are regularly asked to predict accurately.By carefully studying the present, skilled businessmen, scientists, and politicians are supposedly able to figure out in advance what will happen. But can they? One expert on cities wrote: Cities of the future would not be crowded but would have space for farms and fields. People would travel to world in "airbuses" all-weather helicopters carrying up to 200 passengers. When a person left the airbus station he could drive a coin-operated car equipped with radar. The radar equipment of cars would make traffic accidents "almost unheard off\'. Does that sound familiar? If the exert had been accurate it would, because he was writing in 1957. His subject was "The city of 1982". If the professionals sometimes sound like high-school students, it\'s probably because future study is still a new field. Here is an example for future study. Economic forecasting, or predicting what the economy will do, has been around for a long time. But there have been some big mistakes in this field, too. In early 1929, most forecasters saw an excellent future for the stock market. In October of that year, the stock market had its worst losses ever, ruining thousands of investors who had put their faith in financial foreseers. One forecaster knew that predictions about the future would always be subject to significant errors. In 1957, H. J. Rand of the Rand Corporation was asked about the year 2000, "Only one thing is certain," he answered. " Children born today will have reached the age of 43."【单选题】

A.In early 1929, most forecasters saw an excellent future for the stock market.

B.Children born today will have reached the age of 43.

C.Actually, the article was written in 1958 and the question was, "what will life be like in 1978?"

D.So experts are regularly asked to predict accurately.

E.Scientists are 80 percent accurate in predicting the future.

F.The radar equipment of cars would make traffic accidents "almost unheard off\'.

正确答案:C

答案解析:第1段主要介绍对未来的预测。作者问读者，所列的各种高科技的发展的预测是不是会在2000年发生？本题所在的句子说，实际上有人预测在1978年会发生。根据这个上下文，选项C填入后，意思是连贯的。1958年写的文章预测20年之后的高科技的发展。

5、Houses of the FutureWhat will houses be like in thirty years\' time? No one really knows, but architects are trying to predict. _____Future houses will have to be flexible. In thirty years\' time even more of us will be working from home. So we will have to be able to use areas of the house for work for part of the day and for living for the rest. Families grow and change with children arriving, growing up and leaving home. The house of the future will have to grow and change with the family. Nothing will be as fixed as it is now. The house will always be changing to meet changing needs.Everyone agrees that in thirty years\' time we will be living in "intelligent" houses. We will be able to talk to our kitchen machines and discuss with them what to do. Like this, "We\'ll be having a party this weekend. What food shall we cook?" And the machine will tell us what food we will have to buy and how to cook it. We will be able to leave most of the cooking to the machines, just tasting things from time to time to check.The house of the future will be personal, each house will be different. You will be able to change the color of the wall easily.You won\'t have to paint them-you\'ll be able to tell the wall to change the color! And if you don\'t like the color the next day, you will be able to have a new one. The only thing you won\'t be able to do is move the house somewhere else!【单选题】

A.You will be able to change the color of the wall easily.

B.The only thing you won\'t be able to do is move the house somewhere else!

C.And the machine will tell us what food we will have to buy and how to cook it.

D.What will our home be like then?

E.The house of the future will have to grow and change with the family.

F.The kids might take their bedrooms with them as they leave.

正确答案:D

答案解析:本题的难度较大。需要认真阅读文章，特别是第一段和第二段，可用排除法和代入法。本题的上文谈到了没有人会知道30年后房子是什么样子，但建筑家们正在努力地预测。开头第一句用的是疑问句，下文的第一句就谈到未来的房子要十分灵活，用的是陈述句，可以推测此处很可能继续对未来房屋进行发问来展开文章的叙述，回来看选项，可以先排除A，B，C，F项，把D，E代入文章里，可以发现，D更能符合上下文语境和逻辑，是最佳答案。
