单选题For many people today, reading is no longer relaxation. To keep up their work they must read letters, reports, trade publications, interoffice communications, not to mention newspapers and magazines: a never-ending flood of words. In 21 a job or advancing in one, the ability to read and comprehend 22 can mean the difference between success and failure. Yet the unfortunate fact is that most of us are 23 readers. Most of us develop poor reading 24 at an early age, and never get over them. The main deficiency 25 in the actual stuff of language itself ——words. Taken individually, words have 26 meaning until they are strung together into phrases, sentences and paragraphs. 27 , however, the untrained reader does not read groups of words. He laboriously reads one word at a time, often regressing(退回) to 28 words or passages. Regression, the tendency to look back over 29 you have just read, is a common bad habit in reading. Another habit which 30 down the speed of reading is vocalization―sounding each word either orally or mentally as 31 reads. To overcome these bad habits, some reading clinics use a device called an 32 , which moves a bar (or curtain) down the page at a predetermined(预先确定的) speed. The bar is set at a slightly faster rate 33 the reader finds comfortable, in order to "stretch" him. The accelerator forces the reader to read fast, 34 word-by-word reading, regression and subvocalization(默读)practically impossible. At first 35 is sacrificed for speed. But when you learn to read ideas and concepts, you will not only read faster, 36 your comprehension will improve. Many people have found 37 reading skill drastically improved after some training. 38 Charlce Au, a business manager, for instance, his reading rate was a reasonably good 172 words a minute 39 the training, now it is an excellent 1,378 words a minute. He is delighted that how he can 40 a lot more reading material in a short period of time.

单选题Many people imagine that Alzheimer"s disease, the degenerative disorder that ultimately leaves sufferers with total memory loss, is an inevitable result of aging.

It was at this time【C17】______aluminum was becoming widely available for use in cooking pots. Memory loss, difficulty in【C18】______familiar tasks, and problems with abstract thinking are all【C19】______of the onset of the disease. One unusual feature is its impact on language. It attacks nouns first, 【C20】______verbs. Grammar is one of the last things to go.

单选题{{B}}Passage 3{{/B}} There are many good reasons for great current attention to university-industry relations, but there are troublesome reasons as well. One is that universities are now unusually hungry. There is nothing wrong with hunger. But a hungry man may cut comers in his rush to nourishment, and he may be taken advantage of in negotiations. Fear of this is leading to the threat of protectionism, as exemplified by recent attempts to classify or otherwise control access to university research, including that joint with industry. In designing university-industry connections, protecting interests by high-level negotiations is wrong. Protectionism is dangerous and habit-forming. Circumstances exist where it is appropriate, but only for a short time. One of the few essentials of agreements is that any secrecy or interference with open publication or student interaction should be strictly temporary. The dominant problem of supporting enough basic research in universities will remain. This must continue to be a federal responsibility; no company or industry can harvest the results soon enough to justify any investment larger than keeping a window on basic research and conduit for the movement of bright young people into the company. Hard work in the universities will lead to important cooperative research agreements with industry, but unremitting effort will be required to maintain or enlarge the basic research on which all else rests. But there is far more at stake than support for universities. University-industry interaction should not be looked upon as support at all, but as an absolutely necessary part of the survival both of American institutions and of the American economy. As the economy stumbles, protectionism of all kinds becomes rampant, and everyone loses. From the university's standpoint, cooperative projects with industry affect graduate (and even undergraduate) work in healthy ways. To use Harvey Brooks's phrase, giving students "respect for applied problems" is an important part of their education. Wisdom begins when students (and even professors) realize that an invention is not a product and a product is not an industry. What is perhaps most at stake is attracting some of the ablest young people to those fields that can make a difference in the survival of our society. Particle physics ought to be done, just as art galleries ought to be maintained, and the richer the country is the more particle physics and art galleries it should support. But it would be a disaster if protectionism, of either the government or the industry variety, were to discourage some of the best young people from going into applied fields.
