    Here's one very simple yet potentially lifechanging advice I first heard from Brian Tracy.   1    Instead use that hour to read books that could improve your life.
    If you're in sales, Google or browse Amazon for what other people think are the best and most useful books on improving your sales.
        2      . Maybe you want to improve your health, become a more energetic person with a better looking body. Or maybe you want to improve your productivity, your relations or perhaps do some general personal development.
    One hour a day is not much. But if you read for one hour a day on weekdays, that's about 260 hours a year.   3    If applied everyone knows what great things and feelings could come into your life this year.
    Also, all that cool information and useful advice will start to open up your mind. You will start to see more possibilities in your everyday life.
      4       
    1. I really don't have the money...
    Answer: Visit your local library or search their database if they got a website. Or look for used copies in places like amazon.com or some more local alternative if you're outside of the US.
    2. Yeah, ok, but I really don't have the time...
    Answer: Buy the books as audio books and listen to them in the car while driving to and from work. Or transfer them to your mp3-player and listen while riding your bike/bus to work or school. Recently selling audio books directly through mp3-downloads have become popular. It's probably something we will see more and more as people and companies discover this easy (and if the technology works) smooth way of shopping.
    So start browsing for recommendations on books or ask your friends and colleagues.
      5  
    A. Now, you might think something like this:
    B. This of course applies to all fields, not just the work related ones.
    C. All these possibilities in your everyday life will help solve the following problems:
    D. And shut of the TV a little earlier and start reading this week.
    E.  That's a lot of books and loads of useful advice.
    F.  Cut down on the TV at night by just one hour.
    G.  In a word, more recommendations on books will help you find good books.

序数词的构成与用法

1、序数词的构成:

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

2、序数词的用法:
①序数词在使用时,一般加上定冠词。

        Thousands of people died in the earthquake.

如:five dozen (of) eggs   五打鸡蛋
