說到荒漠你會想到什么?荒涼?干燥?駱駝?仙人掌?還是一望無際的黃沙?你知道嗎?一個地方能否被稱為荒漠,并不是根據(jù)其被沙覆蓋的面積大小,而是根據(jù)降雨量的多少。而且,荒漠的種類也并不只有一種呢。下面就跟著小編姐姐一起來了解更多的荒漠知識吧!
What is a Desert?什么是荒漠?
A desert is an area that gets less than 10 *inches
(25.4 centimeters) of precipitation a year.
*inch /Int?/:英寸(復(fù)數(shù):inches)。在荷蘭語中的本意是大拇指,一英寸就是一節(jié)大拇指的長度。但因為每個人的大拇指長短不一,所以在14世紀時,英國國王愛德華二世頒布了“標準合法英寸”:從大麥穗中間選擇三粒最大的麥粒并依次排成一行的長度就是一英寸。一般來說,1英寸約等于2.54厘米。
What is Precipitation?什么是降水?
Precipitation isnt just rain. It can be drizzle, rain, snow, ice crystals or hail.
Words
desert /?dez?t/ n.荒漠;沙漠
precipitation /pr??s?p??te??(?)n/ n.降水
ice crystal冰晶
centimeter /?cent?mi∶t?(r)/ n.厘米
drizzle /?dr?z(?)l/ n.細雨,毛毛雨
hail /he?l/ n.冰雹
The Largest Lce Desert最大的白色荒漠
Not all deserts are hot. They can be in really cold areas too!
There is a desert at the South Pole, called Antarctica. Its the worlds largest ice desert. What makes Antarctica so different to other deserts? The answer is that the snow there never melts and goes away.
The Largest Sand Desert最大的沙漠
The largest sand desert in the world is the Sahara Desert in North Africa. There are lots of sand dunes. Some of them are as high as 500 *feet (152.4 meters). The Nile River flows through the Sahara Desert.
*foot /fut/:英尺(復(fù)數(shù):feet)。在古代,因為沒有國際公認的度量單位,所以英國人往往使用自己的腳來實地測量距離和面積。久而久之,一種基于成年男子單腳的長度就被公認為英國等國家認可的標準度量衡。一般來說,1 foot=12 inches。
No. During the day it can be extremely hot, but at night you need to dress up warm! It can get really cold. You have to take lots of different clothes if you are going to have a desert adventure.

Know More:
撒哈拉沙漠(The Sahara Desert),位于非洲北部,約形成于250萬年前,是世界第三大荒漠(僅次于南極和北極),也是世界上最大的沙質(zhì)荒漠。該地區(qū)氣候條件非常惡劣,是地球上最不適合生物生存的地方之一。
尼羅河(The Nile River),是世界上最長的河流。它流經(jīng)非洲東部與北部,自南向北注入地中海。尼羅河有兩條主要的支流:白尼羅河和青尼羅河。尼羅河河谷一直是棉田連綿、稻花飄香,就像一條處于撒哈拉沙漠和阿拉伯沙漠之間的綠色長廊,充滿無限生機。尼羅河被印第安人稱作“月亮的眼淚”。
