2、A special educationVideodisc holds great promise of helping to meet the needs of American schoolchildren who have problems seeing, hearing, speaking, orsocializing. Almost eleven percent of the students aged 3-21 in this country have an impairment that affects their ability to benefit from a regular education program. Handicapped students require special education because they are often markedly different from most children in one ormore of the following ways: mentally retarded (发展迟缓的) learning-disabled, emotionally disturbed, deaf, visually handicapped, physically handicapped, orother health impairments. The education of these handicapped children is rewarding but challenging. A special education student usually needs a longer period of time to acquire information. Repetitive teaching techniques are often beneficial, and indefatigable (孜孜不倦) consistency on the part of the teacher is frequently necessary. Interactive videodisc courseware has characteristics that can be capitalized upon to meet the challenges that special education poses. A videodisc program is infinitely patient. Repetition of any videodisc lesson can continue endlessly, and designers can assure absolute consistency within a program. Most important, according to special educatorWilliam Healey of the University of Arizona, is that videodisc "adds an extra dimension of realism forchildren who need graphic representations."Healey explained that deaf and mentally retarded children especially have difficulty grasping figurative language and higher-orcerlanguage concepts. He believes that forspecial education, the power of videodisc lies in the ability of the technology to visually represent language concepts normally taken forgranted by non-handicapped persons. Complex figurative language forms such as idioms and metaphors come most readily to mind as being difficult forhandicapped learners. The best phrase that summarizes the main idea of the text is ______【单选题】
A.handicapped students and their problems
B.videodisc and special education
C.computer assisted teaching programs
D.normal children and handicapped kids
正确答案:B
答案解析:通读全文可知,文章主要介绍了对残疾孩子的特殊教育和辅助这种特殊教育的影碟课件,故选B。
3、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. 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 forspreading resistance, he said. The drugs contaminate the crops, which are then eaten. ______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:F
答案解析:选项F中的also 一词说明前面应讲到过一个类似的内容。这句讲的是这些药物可能从施过肥料的农田下面的岩石沥滤到自来水里去;前面一句讲的是受到这些药物污染的谷物被人食用,这两句讲的都是这些药物如何对人类造成威胁。
4、Meet Your Memory1. Memory is something that cannot be seen, touched orweighed. It is thought to be abstract. It is a setof skills rather than an object. Neither is there a single standard forjudging a good orpoormemory. There are a number of different ways in which a person may have a good memory.2. Memory is generally viewed as consisting of three stages: (1) acquisition refers to learning the material; (2) storage refers to keeping the material in the brain until it is needed; (3) retrieval (提取) refers to getting the material back out when it is needed:3. Memory consists of at least two different processes: short - term memory and long - term memory. Short - term memory has a limited capacity and a rapid forgetting rate. Its capacity can be increased by chunking (组成大块), orgrouping separate bits of information into larger chunks. Long - term memory has an almost unlimited capacity.4. One measure of memory is recall, which requires you to produce information by searching the memory forit. In aided recall, you are given cues (提示) to help you produce the information. In free - recall learning you recall the material in any order. In serial learning you recall it in the orcerit was presented and in paired - associate learning you learn pairs of words so that when the first word is given you can recall the second word. A second measure of memory is recognition, in which you do not have to produce the information from memory, but must be able to identify it when it is presented to you. In a third measure of memory, relearning, the difference between how long it took to learn the material the first time and how long it takes to learn it again indicates how much you remember. Relearning is generally a more sensitive measure of memory than is recognition because relearning shows retention (保持) while recognition does not. Recognition is generally a more sensitive measure than recall.Long - term memory has an almost unlimited capacity and a ______.【单选题】
A.short - term memory
B.relearning
C.needed
D.coded
E.recognition
F.slow forgetting rate
正确答案:F
答案解析:本题有一定难度,需要认真第三段,吃透句意。这一段谈到短期记忆和长期记忆是两个不同的过程,短期记忆遗忘率高,那么换句话说长期记忆遗忘率低,回来看选项,F项slow forgetting rate符合原文句意,是答案。
5、Singing Alarms Could Save the BlindIf you cannot see, you may not be able to find your way out of a burning building and that could be fatal. A company in Leeds could change all that with directional sound alarms capable of guiding you to the exit. Sound Alert, a company run by the University of Leeds, is installing the alarms in a residential home for______ people in Sommersetand a resource centre forthe blind in Columbia. The alarms produce a wide range of frequencies that enable the brain to determine where the sound is coming from. Deborah Withington of Sound Alert says that the alarms use most of the frequencies that can be heard by humans. "It\'s a burst of white noise that people say sounds like static on the radio," she says. "Its life-saving potential is great."She conducted an experiment in which people were filmed by thermal-imaging cameras trying to find their way out of a large smoke-filled room. It took them nearly four minutes to find the doorwithout a sound alarm, but only 15 seconds with one. Withington studies how the brain processes sounds at the university. She says that the source of a wide band of frequencies can be pinpointed more easily than the source of a narrow band. Alarms basedon the same concept have already been installed on emergency vehicles. The alarms will also include rising orfalling frequencies to indicate whether people should go up ordown stairs. They were developed with the aid of a large grant from British Nuclear Fuels. 【单选题】
A.slow
B.deaf
C.blind
D.lame
正确答案:C
答案解析:这篇文章的核心内容就是有关盲人警报器的,而且后半句也提到a resource centre forthe blind,所以顺理成章地得出结论答案应是C。
