    Tips for Being a Good Neighbor
    小题1:_______________
    No one likes a noisy neighbor. Do you hold parties that last all night? Do you leave your dog outside to bark all day? Remember that not everyone has the same schedule as you do, so use some common sense. Keep noise to the lowest level. If you’re holding a party that’s likely to be loud, invite everyone within earshot.
    小题2:_______________
    It’s much easier to solve any problem with neighbors if you have a friendly relationship with those around you. Furthermore, you may realize that you have things in common and make a lifelong friend.
    小题3:_______________
    Once you know your neighbors, then you’ll also know if something seems out of place in the neighborhood. Are strange people carrying expensive things out of one neighbor’s house? Have several days passed since your elderly neighbor last collected his newspaper? The benefit of keeping an eye out for unusual behavior in the neighborhood is that others will do the same for you.
    小题4:_______________
    It never hurts to follow the Golden Rule: Do to others what you would like them to do to you. Treat your neighbors with respect. Offer to drive an elderly neighbor to the grocery store. Volunteer to collect mail while a neighbor is on vacation. The more often you lend a helping hand, the more likely that your neighbors will do the same for you when you need a little help.
    小题5:_______________
    Don’t just limit your neighborly actions to your block or street. Remember that everyone who lives in a community has the ability to help make it a better place. Think about your passion and find a way to do it on a volunteer basis in your town. Volunteer at the local library. Enjoy working with kids. Consider becoming a scout leader. Whatever your passion is, there’s sure to be a thing suitable for you to help in the local community.

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

           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。

        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。

        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
