    For several years, Americans have enjoyed teleshopping — watching TV and buying things by phone. __小题1:__ In a number of European countries, people can turn on their TVs and shop for clothes, jewelry, food, toys, and many other things.__小题2:__ For example, the biggest Swedish company sells different kinds of things on TV in 15 European countries, and in one year it made $100 million. In France there are two teleshopping channels, and the French spend about $20 million a year to buy things through those channels.
    In Germany, until last year teleshopping was only possible on one channel for 1 hour every day. Then the government allowed more teleshopping. Other channels can open for tele-business, including the largest American teleshopping company and a 24-hour teleshopping company. __小题3:__
    Some people like teleshopping because it allows them to do their shopping without leaving their homes. With all the problems of traffic in the cities, this is an important reason, but at the same time, other Europeans do not like this new way of shopping. __小题4:__ Many Europeans usually worry about the quality of the things for sale on TV. Good quality is important to them, and they believe they cannot be sure about the quality of the things on TV.__小题5:__ They will have to be more careful about the quality of the things they sell. They will also have to work harder to sell things that the buyers cannot touch or see in person.
    A.The need for high quality means that European teleshopping companies will have to be different from the American companies.
    B.Teleshopping is popular among people.
    C.German teleshopping business is controlled by American.
    D.Now teleshopping is starting in Europe.
    E. They call teleshopping “Junk on the air”.
    F. Teleshopping is becoming popular in Sweden.
    G. German businesses are hoping this new teleshopping will help them sell more things.

  • 序数词

序数词的概念:

表示顺序的数称为序数词。如:first, second, third, fourth。


序数词的构成与用法

1、序数词的构成:
①一般来说,是由相应的基数词加词尾th构成。
   例:four+th→fourth
           six+th→sixth
           seven+th→seventh
           ten+th→tenth
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。
例:the first book
        the second floor
        the third day
        the fourth week.
②序数词在多数情况下都用作定语,有的也可以作表语、主语和宾语。
例:The may1st is Labour Day. 五月一日是劳动节。
        My room is on the second floor. 我的房间在二楼。
        The first is larger than the secon.(主语)第一个比第二个大。
        Read the book from the first.(宾语)从开头读这本书。
        You'll be the sixth to write.(表语)你将是第六个写的。
③序数词的前面可以加上不定冠词,用来表示“再一”,“又一”的意思。

序数词知识体系:

 


约数的表达方法

用tens/dozens/scores/hundreds/thousands/millions of 表示“几十、几百、上千、成千上万”等。
如:The boy bought dozens of pencils.            
        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
        hree hundred people  三百个人

分数词的构成和用法:

1)分数词构成法:
分数词(FractionalNumerals)由基数词和序数词构成,基数词代表分子,序数词代表分母。除了分子为1的情况下,序数词都要用复数形式:

        2/3:two-thirds
       17/5:three and two-fifths
       7/12:seven-twelfths
