Cactuses
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,它的莖是橢圓形的,并且全身長滿刺,實際上它們身上的刺是它們的葉子.葉于長成這種形狀是為了阻止它們身體內(nèi)的水分蒸發(fā)到熱而干的空氣里.仙人掌長著長長的根,它們把根深深地扎入地底下以便從更深層的土中吸收水分.
它們一般開小而白的花.盡管它們在沙漠里被忽視,但是它們從不放棄開花并且默默地點綴著沙漠.
