    What are the children in post-90s era like?
    By carefully studying and analyzing the interactive relations between the growth of youth and the change of social environment in China, Professor Yang Xiong, a research fellow from Institute of Children's Studies, Shanghai Academy of Social Sciences summarized several similarities shared by the children in post 90s era.
    I. They have an avant-garde(前卫的) concept of consumption and strong desires and lay excessive(过度的) emphasis on the importance and the amount of money and the way how to get money. A survey on under-10 children in Shanghai and Paris over their ideal career in the future showed that children in France preferred the profession of sportsman, rock & roll singer and sailing boat athlete; whereas children in China wanted to be boss, entrepreneur and leader, and desired vehicle and villa. They have been influenced by their parents, schools and the society they lived in to some extent.
    II. They are in great need of a sense of loyalty to teams. Some social phenomena have weakened their interests toward loyalty, and they advocate individualism. Actually, some parents would subconsciously encourage their children to do something selfish rather than contribute to the team.
    III. They are closer to the new media than their parents are and they are prone to(易于) fall the victims during the process of globalization. They have broader visions and possess pluralistic(多元的) ways in accepting information. Meanwhile, they are better developed in terms of psychology and intelligence, with wide range of knowledge and a precocious(早熟的) inner world. But it seems that such qualities more likely to make them feel hollow.
    IV. Some social realities have made them understand that they should pay more attention to concrete things rather than abstract philosophy. And some of them concern more about their comfortable lives and the way of making living.
    Prof. Yang held that the weakness of the children in post 90s era required early attention. Adults, parents should set an example for the children and take the responsibility. Along with the social development, children of post 90s era will become a generation of all-round development.

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。

        the second floor
        the third day

        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.
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
