1、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 forwork forpart of the day and forliving forthe 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 colorof 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 colorthe 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 colorof 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。
2、Radiocarbon DatingNowadays scientists can answer many questions about the past through a technique called radiocarbon (放射性碳), orcarbon - 14 dating. One key to understanding how and why something happened is to discover when it happened.Radiocarbon dating was developed in the late 1940s by physicist Willard F. Libby at the University of Chicago. An atom of ordinary carbon, called carbon -12, has six protons (质子) and six neutrons (中子) in its nucleus (原子核). Carbon - 14, orC - 14, is a radioactive, unstable form of carbon that has two extra neutrons. It returns to a more stable form of carbon through a process called decay (衰减). This process involves the loss of the extra neutrons and energy from the nucleus.In Libby\'s radiocarbon dating technique, the weak radioactive emissions(放射)from this decay process are counted by instruments such as a radiation detectorand counter. The decay rate is used to determine the proportion of C -14 atoms in the sample being dated.Carbon - 14 is produced in the Earth\'s atmosphere when nitrogen(氮) - 14, orN - 14, interacts with cosmic rays (宇宙射线). Scientists believe since the Earth was formed, the amount of nitrogen in the atmosphere has remained constant. Consequently, C -14 formation is thought to occur at a constant rate. Now the ratio of C -14 to other carbon atoms in the atmosphere is known. Most scientists agree that this ratio is useful fordating items back to at least 50,000 years.All life on Earth is made of organic molecules (分子) that contain carbon atoms coming from the atmosphere. So all living things have about the same ratio of C -14 atoms to other carbon atoms in their tissues (组织). Once an organism (有机体) dies it stops taking in carbon in any form, and the C -14 already present begins to decay. Over time the amount of C - 14 in the material decreases and the ratio of C - 14 to other carbon atoms goes down. In terms of radiocarbon dating, the fewer C -14 atoms in a sample, the older that sample is.The radiocarbon dating technique is only about 40 years old.【单选题】
A.Right
B.Wrong
C.Not mentioned
正确答案:B
答案解析:本题有一定难度,需要认真寻找答案依据。主要答案依据在文章第二段第一句:Radiocarbon dating was developed in the late 1940s谈到放射性碳测定法源于20世纪40年代,显然,早就超过了40年历史,所以本题错误,答案是B。
3、Can you give a concrete example to support your idea?【单选题】
A.specific
B.real
C.special
D.good
正确答案:A
答案解析:你可以举一个具体的例子来支持你的观点吗?本题有一定难度,concrete,常用词汇,指“具体的”,specific 一般指“特殊的”引申意思指“具体的”,这里和concrete,是同义词,special指“特殊的”,没有“具体的”意思,最佳答案是A。
4、The orangutanAmong all the animals, the ape is most like human beings. Both people and apes have the similar brain structure, the similar nerve system, and the similar kind of blood. There are four kinds of apes: the chimpanzee (黑猩猩), the orangutan (猩猩), the gorilla (大猩猩), and the gibbon (长臂猿). They live in the deep forests and warm tropical regions of Africa and of Southeast Asia, including Indonesia. All apes are covered with brown, reddish-brown, orblack hair everywhere on their bodies except their faces, feet, and hands. Their hands each have four fingers and a thumb that helps them grip things the way our thumbs help us. But they also have a thumb on each foot instead of a big toe. Thus they can hold things with their feet also. Having short, weak legs, apes do not walk on the ground very much. However, their arms are very strong. This enables them to swing from branches and travel very quickly from tree to tree. These animals live in small family groups that move from place to place in search of vegetables and fruits. They also eat eggs, small animals, nuts, and insects. When they are tired, they build nests in the trees. But they rarely sleep there formore than a night ortwo. Then they move on to look formore food. There are some differences among the following three kids of apes. The gibbon is never more than three feet high and weight only about fourteen pounds. The gorilla grows to be six feet tall and weight up to 600 pounds. The orangutan is smaller than the gorilla. It stands three to five feet tall and weight up to 200 pounds. Chimpanzees are the smartest of all apes. They can be taught to sit at a table and eat, to dress themselves, and to do things that human children can do. The last paragraph tells us that____. 【单选题】
A.chimpanzees can do better than human children
B.chimpanzees can do many things that human children cannot do
C.human children can do many things that chimpanzees cannot do
D.the intelligence of chimpanzees is similar to that of human children
正确答案:D
答案解析:文章最后一段指出,黑猩猩是所有猿中最聪明的,可以做人类儿童能做的事情,由此推断,黑猩猩的智力与人类儿童的智力相似,故选D。
5、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 unionand the US each year. More than half are given to farm-animals to prevent disease and promote growth. 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. 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 forEnvironmental Science and Technology in Dubendorf. ______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 forspreading 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 agroupof antibiotics called sulphonamides. They do not easily degrade ordissolve 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 ordissolve 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:B
答案解析:选项B中有两处提示:一是本句结尾处的he says,说明上文中必提到一个被引用的人;二是句首的And,这个词表明,这句的内容可能是前一句的延续。前一句引的S. Mueller说的话讲到,在肥料中滞留的药物比肉类产品中多得多。这句话则继续引用Mueller的话,进一步说肥料中对抗生素有抗药性的病菌含量特别高。
