    A punctual person is in the habit of doing a thing at the proper time and is never late in keeping an appointment.The unpunctual man, on the other hand, never does what he has to do at the right time. 小题1:
    There's a proverb which says,“Time flies never to be recalled.” This is true.小题2:The unpunctual man is forever wasting his most valuable possessions as well as others'.The unpunctual person is always complaining that he finds no time to answer letters, or return calls or keep appointments.小题3: He knows that he can get through his huge amount of work only if he faithfully keeps every appointment and deals with every piece of work when it has to be attended to.
    小题4: .If a person is invited to dinner and arrives later than the appointed time, he keeps all the other guests waiting for him.Usually this will be regarded as rude both to the host and the other guests.
    Unpunctuality, moreover,is very harmful when it comes to one's duty.Imagine how it would be if those who are put in charge of important tasks failed to be at their proper place at the appointed time.小题5:
    A.They appear to be busy but never get well paid.
    B.He is always in a hurry and ends up losing time.
    C.Maybe nobody minds being kept waiting at a dinner party.
    D.A lost thing may be found again, but lost time can never be regained.
    E.But the man who really has a great deal to do is very careful of his time.
    F.A man who is known to be habitually unpunctual is never trusted by others.
    G.Failure to be punctual in keeping one's appointment is a sign of disrespect towards others.

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。
