    English, you are so popular
    English is the world language, the language of international communication in many areas of life; trade, air and sea transport, tourism and sport. New ideas in science, technology and medicine happen so quickly that it is impossible and very expensive to translate everything into different languages. 小题1:   If you want to study some subject, you need to know professional words and phrases.
    English is used as a first language in countries such as Australia, Canada, Ireland, New Zealand, the USA and many of the countries in the Caribbean. 小题2:  It is a way in which people who have different languages communicate with each other. This is especially true in many parts of Africa and India.
      小题3:  Australian, American or Irish English has another pronunciation or stresses, so sometimes you cannot understand, although you can speak English. The USA has no official national language. English is used like a natural language by all Americans, because it is very simple. The American variety is popular between no-native speakers, too.
    English is far more worldwide in its distribution(分布) than all other spoken languages. 25% to 33% of the people in the world understand and speak English to some degree. And most of them can use English freely. 小题4: 
    In 2001, the 189 member countries in the United Nations were asked what language they wished to use for communication with other countries. More than120 chose English, 40 selected French, and 20 wanted to use Spanish. 小题5:  However, the percentage of Internet users who are not native English speakers is increasing rapidly, especially in Asia.
    A.It has become the most useful language.
    B.Therefore, most things are published in English.
    C.In other countries it is used as a second language.
    D.However, English in all these countries is not the same.
    E.English is also the language particularly on the Internet.
    F.There are at least 165 languages spoken in the United States.
    G.Therefore, it is not surprising that all languages change through time.

  • 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
