Cactuses 仙人掌

Cactuses are used to living in desert. The whole body of a cactus is green. The stalk is oval and there are thorns all over its body. Actually the thorns in their bodies are their leaves. The leaves are like this only because they can stop the water in their bodies from evaporating into the hot and dry air. The cactuses have long roots and they take their roots deep into the earth so that they can get the water from deeper,soil.

Their flowers are always small and white.Although they are ignored in the desert, they never give up coming ont and alwaysdecorate the desert silently.

仙人掌通常生長在沙漠里。它通身綠色。柄是橢圓形，它渾身帶刺。實際上它們身上的刺是它們的葉子。這樣的樹葉僅僅是因為他們可以阻止水從他們的身體蒸發(fā)進入炎熱和干燥的空氣。仙人掌的根很長，他們自己的根深入到土地，使他們能夠更深得到水，土。

他們總是有白色的小花。盡管它們在沙漠里被忽視，但是它們從不放棄開花，默默地點綴著沙漠。
