    Green is an important color in nature. It is the color of grass, the leaves on trees and most growing plants. Sometimes, the word green means young, fresh and growing. Sometimes, it describes something that is not yet ripe or finished. For example, a greenhorn is someone who has no expereince, who is new to a situation.  In the 15th century, a greenhorn was a young cow or ox whose horns had not yet developed.  A century or so later, a greenhorn was a soldier who had not yet had any experience in battle. By the 18th century, a greenhorn had the meaning it has today.
    Someone who has the ability to grow plants well is said to have a green thumb. The expression comes from the early 1990s. A person with a green thumb seems to have a magic touch that makes plants grow quickly and well. You might say that the woman next door has a green thumb if her garden continues to grow long after your plants have died.
    The Green Revolution is the name given some years ago to the development of new kinds of rice and other grains. The new plants produced much larger crops.  The Green Revolution was the result of hard work by agricultural scientists who had green thumbs.
    Green is also the color used to describe the powerful emotion, envy. The green-eyed monster is not a terrible creature from outer space.  It is an expression used about four hundred years ago by British writer William Shakespeare in his play “Othello.” It describes the unpleasant feeling a person has when someone else has something he wants.  A young man may suffer from the green-eyed monster if his girlfriend begins going out with someone else. Or, that green-eyed monster may affect your friend if you get a pay rise and she does not.

  • 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:

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:

        5/9:five-ninths
        2/3:two-thirds
       17/5:three and two-fifths
       7/12:seven-twelfths
