    Questions:
    A. Do you think people should be decisive in the wild?
    B. How to make hunting tools?
    C. Do you think people should send an SOS while they are in danger?
    D. How to make a fire in the wild?
    E. How to set a trap to hunt animals?
    F. How to build a shelter in the wild?
    小题1:______
    Answer: If you are in a desert environment, try to build an underground shade shelter to avoid prolonged sun exposure, obviously only for hot climates. So you can be more comfortable in cooler temperatures to avoid sweating. If your environment is damp, use branches laid and criss-crossed on top of one another to create a solid and dry foundation for an open bed pad. Raise the foundation above ground level as much as possible.
    小题2:______
    Answer: Yes, I think so. For example, if you think the best survival course of action is to look for help and civilization, don’t wait 4 or 5 days before you come to this conclusion. Take action on the 1st or 2nd day if possible while you still have strength and endurance working for you.
    小题3:______
    Answer: Use dry wood and sticks to start your fire. Fire is started by using three kinds of wood: tinder, kindling, and fuel. Tinder is any kind of flammable wood shavings, usually light and wispy. You can take two pieces of dry wood, sharpen one of them and use it to drill into the other piece. Place any highly flammable objects you can find next to the drill bit. The moment the flammable object catches a spark, use a rock to swiftly tip the object onto a nest of leaves and little branches.
    小题4:______
    Answer: Get an ordinary block of wood and hit it with a rock repeatedly until the wood sharpens. In this case, use the rock as your sharpener. You could also take a rock and break off some of the edges and then use another rock and some water like a wet stone and sharpen. In an ideal situation, obsidian stone would be used for its infamous sharpness.
    小题5:______
    Answer: Use two more sticks to hold up a “teepee”, similar to your shelter. Place an item of your choice you think an animal will come after, if you’re lucky, the animal will be trapped. Dig a hole in the ground about 2m-3m deep and 1m-2m across. Take two thin branches and place them criss-crossed across the hole. Cover it with leaves and put something the animals like to eat. You can also put a few wooden spikes sharpened by your knife at the bottom. Don’t forget to build a ladder or you might not be able to climb out of the hole.

  • 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:
分数词(FractionalNumerals)由基数词和序数词构成,基数词代表分子,序数词代表分母。除了分子为1的情况下,序数词都要用复数形式:
如:1/4:one-fourth
        5/9:five-ninths
        2/3:two-thirds
       17/5:three and two-fifths
       7/12:seven-twelfths
       379/8:forty-seven and three-eighths
此外还有下面表示法:
如:1/2:a(one) half
        1/4:a(one) quarter
        3/4:three-quarters
        9/4:two and a quarter
        3/2:one and half
        31/4:seven and three quarters
