    Expressions about water are almost as common as water.    小题1:        
    The expression “to be in hot water” is one of them. It is a very old expression. “Hot water” was used five hundred years ago to mean being in trouble. One story says it got that meaning from the custom of extremely throwing hot water down on enemies attacking a castle. When we are in “hot water”, we are in trouble.    小题2:    A young boy can be in hot water with his mother if he comes into the house with dirty shoes.
      小题3:    A company seeks to keep its head above water during economic hard times. A man who loses his job tries to keep his head above water until he finds a new job.
    Another common expression, “to hold water”, is about the strength or weakness of an idea or opinion that you may be arguing about. If it can hold water, it is strong and has no holes in it. If your argument can hold water, it is strong and does not have any holes.  小题4:   
    “Throwing cold water” also is an expression that deals with ideas or proposals. 小题5:    For example, you want to buy a new car because the old one has some problems. But your wife “throws cold water” on the idea, because she says a new car costs too much.
    A.It means disliking an idea.
    B.You are in a difficult situation.
    C.A person who breaks a law can be in hot water with the police.
    D.If it does not hold water, then it is weak and not worth debating.
    E. But many of the expressions using water have unpleasant meanings.
    F. A man who has long been jobless will find it hard to make both ends meet.
    G. “To keep your head above water” is a colorful expression that means staying out of debt.

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.

        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。

        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
