    A.Option of home schooling is around for a long time
    B.Recent years’ growth of home schooling
    C.The unpleasant situation of school education
    D.Advantages in home schooling
    E.Parents should be responsible for child’s education
    F.Home schooling is not a perfect choice
    小题1:Home schooling is an option that is becoming more attractive to parents as time goes on. Schools have become increasingly unstable over the past couple of decades. The textbooks are outdated, violence is common, children are shot without mercy, and the quality of education on the whole has greatly diminished.
    小题2:The option of home schooling has been around for a long time; however, until recently it had not been so popular. The idea of home schooling seems like a cure-all to many parents due to the advantages this type of education provides over traditional schools.
    小题3:Children who are home schooled can avoid many of the problems schools have become known for. For one, the environment is less threatening. Children can learn without fearing other students. In addition, home schooling allows parents to dictate the academic course of their children. Home schooling also allows students to proceed at their own speed. If a child is weak at multiplication and division, a parent can focus lessons on those skills in favor of another skill that the child might understand rather easily.
    小题4:It may sound like the perfect option, but there are many disadvantages of home schooling. First of all, home schooled children are usually less socialized. While schools can sometimes be the breeding ground for poor social behaviors, school is also a place where students learn to interact with others and build social skills. In addition, another drawback to home schooling could be implementation of an educational plan. Many parents are not qualified as teachers and may not understand what is necessary to ensure a child has access to the proper curriculum.
    小题5:Finally, another disadvantage to home schooling is the necessity for parents to take full responsibility for their child’s education. If you choose to home school your child, there is no one for you to blame if your child does poorly. The responsibility falls completely on the parent.

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。

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
