    小题1:The debate has been raging for years over the safety of, and necessity for, childhood vaccinations, which has been so much so that it is termed "The Vaccine War". The debate has only a few moments that might be inspiring to those who have been following this now familiar issue.
    小题2:There are certainly benefits of using a star in a film. It makes the film easier to market. Stars also help sell more tickets and drive DVD sales, which are a big part of studio revenue. However, a star does not guarantee success. The simple fact is that if you pay a star a great deal of money for a film that people don't want to see, then it won't work.
    小题3:They are barely in their twenties and are already multimillionaires. At the age when many people are looking for their first job, the youngsters of The Sunday Times Rich List are buying country estates or jetting off to their overseas homes. Daniel Radcliffe, for example, who plays Harry Potter, has a fortune of 42 million, at 20.
    小题4:Millions of jobless Americans, who might be suffering in anxiety and lacking a sense of security, are showing up at emergency rooms of state-owned hospitals, contributing to a longer waiting time and a higher risk of cursory treatment by overworked doctors and nurses.
    小题5:Alice Miller, a psychology expert, who died at 87 at home in Provence, France, on April 14, repositioned the family as a central place of abnormal psychological function with her theory that parental power and punishment lay at the root of nearly all human problems.

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
        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。

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
