    Alfred Alder, a famous psychiatrist, had    小题1:      interesting experience. When he was a small boy he got off to a poor start in arithmetic(算术). His teacher got the idea that he had no ability in arithmetic, and told his parents     小题2:     she thought in order that they would not expect too much of him. In this way, they too developed the idea, “ Isn’t    小题3:    too bad that Alfred can’t do arithmetic?” He accepted their mistaken estimate of his ability,    小题4:    (feel) that it was useless to try, and that he was very poor at arithmetic, just as they expected.
    One day he became very angry at the teacher and the other students because they laughed when he said he saw how to do a problem which none of the other students had been able to solve.
    Adler succeeded   小题5:  solving the problem. This gave him     小题6:    (confident). He rejected the idea that he could not do arithmetic and was     小题7:     (determine) to show them that he could. His anger and his new found faith stimulated him to go at arithmetic problems with a new spirit. He now worked with interest, determination, and purpose, and he soon became   小题8:    (extraordinary) good at arithmetic. He not only proved that he can do arithmetic, but he learned early in life from his own experience ,      小题9:   a person goes at a job    小题10: determination and purpose, he may astonish himself as well as others by his ability.

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。

如:The boy bought dozens of pencils.            
        Thousands of people died in the earthquake.

如:five dozen (of) eggs   五打鸡蛋
