passage 1（1994年）
    the first and smallest unit that can be discussed in relation to language is the word. in speaking, the choice of words is     41     the utmost importance. proper selection will eliminate one source of     42     breakdown in the communication cycle. too often, careless use of words     43     a meeting of the minds of the speaker and listener. the words used by the speaker may     44     unfavorable reactions in the listener     45     interfere with his comprehension; hence, the transmission-reception system breaks down.
       46     inaccurate or indefinite words may make     47     difficult for the listener to understand the     48     which is being transmitted to him. the speaker who does not have specific words in his working vocabulary may be     49     to explain or describe in a     50    that can be understood by his listeners.

                                         passage 2（1995年）
     sleep is divided into periods of so-called rem sleep, characterized by rapid eye movements and dreaming, and longer periods of non-rem sleep.     41     kind of sleep is at all well understood, but rem sleep is     42     to serve some restorative function of the brain. the purpose of non-rem sleep is even more     43    . the new experiments, such as these     44     for the first time at a recent meeting of the society for sleep research in minneapolis, suggest fascinating explanations     45     of non-rem sleep.
    for example, it has long been known that total sleep     46    is 100 percent fatal to rats, yet,     47     examination of the dead bodies, the animals look completely normal. a researcher has now     48     the mystery of why the animals die. the rats     49    bacterial infections of the blood,     50     their immune systems — the self-protecting mechanism against diseases-had crashed.

passage 3（1996年）
    vitamins are organic compounds necessary in small amounts in the diet for the normal growth and maintenance of life of animals, including man.
    they do not provide energy,     41     do they construct or build any part of the body. they are needed for     42     foods into energy and body maintenance. there are thirteen or more of them, and if     43     is missing a deficiency disease BEComes     44    .
    vitamins are similar because they are made of the same elements — usually carbon, hydrogen, oxygen, and     45     nitrogen. they are different     46     their elements are arranged differently, and each vitamin     47     one or more specific functions in the body.
        48     enough vitamins is essential to life, although the body has no nutritional use for     49     vitamins. many people,     50    . believe in being on the "safe side" and thus take extra vitamins. however, a well-balanced diet will usually meet all the body’ s vitamin needs.

    manpower inc, with 560,000 workers, is the world’s largest temporary employment agency. every morning, its people     41     into the Offices and factories of america, seeking a day’s work for a day’s pay. one day at a time.     42     industrial giants like general motors and ibm struggle to survive     43     reducing the number of employees, manpower, based in milwaukee, wisconsin, is booming.

passage 5（1998年）
    until recently most historians spoke very critically of the industrial revolution. they     41     that in the long run industrialization GREatly raised the standard of living for the     42     man. but they insisted that its     43     results during the period from 1750 to 1850 were widespread poverty and misery for the     44     of the english population.     45     contrast, they saw in the preceding hundred years from 1650 to 1750, when england was still a     46     agricultural country, a period of great abundance and prosperity.
    this view,     47    . is generally thought to be wrong. specialists     48     history and economics, have     49     two things: that the period from 1650 to 1750 was     50     by great poverty, and that industrialization certainly did not worsen and may have actually improved the conditions for the majority of the populace.
