    There are a number of advantages when it comes to living alone. However, it also comes with a few safety concerns. You still never know who will be around the corner. Don’t become another victim; be sure to follow our tips.
    1. All doors should be kept locked.
    Always keep your doors locked when you are in your apartment or dorm. Make sure the doors are closed behind you when you come into the building and never leave your room unlocked, even when you are in it. There’s always a chance that someone might sneak in while you are unaware. Always try to remember to close doors behind you to ensure your safety.
    2. Don’t lose your keys.
    Even if you do everything you can to keep the doors locked, criminals might still be able to come into your house with a key. Always know where your keys are to prevent this. Never put them down in a public place or give them to friends. Also, before you bring your car into the repair shop, take off the house keys.
    3. When it comes to safety, standing up for yourself is important.
    If you aren’t getting all the security features you want, don’t be afraid to ask. If your lighting situation is less than ideal, discuss this with your supervisor or landlord. Talk to the campus security organization if you think a security phone near your dorm is a good idea. Request that the building employ someone to monitor those entering and leaving the building. You should feel safe where you reside (居住于), so stand up for your rights.
    4. Be careful.
    You still might find yourself in a potentially dangerous situation. Check your peephole (窥视孔) before letting anyone in. Whenever you witness something around your building that makes you uncomfortable or suspicious just dial 911. It is a good idea to always walk with a friend instead of alone. Become familiar with people who live in the building, so you can keep track of anyone that is a stranger.

  • 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。

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:

        5/9:five-ninths
        2/3:two-thirds
       17/5:three and two-fifths
       7/12:seven-twelfths

        3/4:three-quarters
        9/4:two and a quarter
        3/2:one and half
