    Directions: Read the following text and choose the most suitable heading from the list A-F for each paragraph.  There is one extra heading which you do not need.

    B.The effect of the situation on farmers.
    C.The variety of British food.
    D.The surface richness of food and questions it brings.
    E. The different situations at home and abroad.
    F. The recent reason for the huge supply of food.
     
    1
    The long years of food shortage in Britain have suddenly given way to huge food supply.  Stores and shops are crowded with food.  Rationing(定量供应) has already seemed too distant to today’s Britons.  Even overseas suppliers have been asked to hold back deliveries.  Yet, instead of joy, there is widespread uneasiness and worries.  Why do food prices keep on rising, when there seems to be so much more food about?  Is the surface huge amount of food only temporary, or has it come to stay?  Does it mean that we need to think less now about producing more food at home?
    2
    The recent growth of food supply on the world food market has certainly been unexpectedly great, partly because two continuous big grain harvests in North America are now being followed by a third.  Most of Britain’s overseas suppliers of meat, too, are offering more this year and home production has also risen.
    3
        Then why is the food situation in Britain still faulty?  On the one hand, The British government has gradually cut down support for food.  On the other hand, the shops are overstocked with food not only because there is more food available, but also because people, frightened by high prices, are buying less of it.
    4
        Moreover, the rise in food prices at home has come at a time when world prices have begun to fall, with the result that imported food, with the exception of grain, is often cheaper than the home-produced variety.  And now grain prices, too, are falling internationally.  British consumers are beginning to ask why they should not be able to benefit from this trend.
    5
    The significance of these developments is not lost on farmers.  The older generation have seen it all happen before.  Despite the present price and market guarantees, farmers fear they are about to be squeezed between cheap food imports and a smaller home market.  Present production is running quickly compared with years ago.  However, farmers haven’t shared any benefit from the change.

②下面这些基数词在变为序数词时,有特殊的变化。
例:one→first
        two→second
        three→third
        five→fifth
        eight→eighth
        nine→ninth
        twelve→twelfth
③十位整数序数词的构成方法是将基数词的词y变成i,然后再加eth。
例:twenty→twentieth
        thirty→thirtieth
        forty→fortieth
        ninety→ninetieth
④两位或两位以上的基数词变成序数词时,仅将个位数变成序数词。
例:twenty-one→twenty-first
        thirty-five→thirty-fifth
        a hundred and fifty-three→a hundred and fifty-third

2、序数词的用法:
①序数词在使用时,一般加上定冠词。

        Thousands of people died in the earthquake.
注意: (A):dozen, score, hundred, thousand, million等表示确切数量时,不用复数。
如:five dozen (of) eggs   五打鸡蛋
