    “We are reading the first part of the first section of a book whose pages are never-ending.”
    _71_ We can take the mysterious, unknown future and carve out of it anything that we can imagine, just like a sculptor carves a statue from a shapeless stone.
    _72_ If we plant a good seed, we get in a good harvest; if our seed is poor and the field is full of weeds,we get in a useless crop; if we plant nothing at all, we get in nothing at all.
    I want the future to be better than the past. We should all be concerned about the future because that is where we will spend the rest of our lives. _73_
    _74_ Nothing we can do will change it.
    The future is before us and dynamic. _75_ Each day will bring it with new frontiers, in our homes and in our business, if we will only recognize them. We are just at the beginning of the progress in every field of human effort.
    The past is gone forever.
    I don’t know who wrote those words, but I have always liked them as a reminder that the future can be anything we want to make it.
    We should never forget the rapid change in the past few years.
    We are all in the position of the farmer.
    Everything we can do will affect it.
    We are able to travel easily anywhere we want to go in the future.
    We whould not let our past mistakes and errors damage it.

  • 序数词

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。
例:You may have a third try. 你可以第三次尝试。


序数词知识体系:

 


约数的表达方法

用tens/dozens/scores/hundreds/thousands/millions of 表示“几十、几百、上千、成千上万”等。
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

分数词的构成和用法:

1)分数词构成法:
