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 out and always decorate the desert silently.

仙人掌通常生长在沙漠。仙人掌的整个身体是绿色。它的茎是椭圆形的，它的身体布满了刺。事实上它们身上的刺是它们的叶子。叶子（成长）这样仅仅是因为他们可以阻止身体内的水分蒸发到炎热和干燥的空气。仙人掌长着长长的根，他们的根深入土壤，使他们能够从更深的土壤得到水。
他们的花总是白色而且很小。尽管它们在沙漠里被忽视，它们从不放弃开花并且默默地点缀着沙漠。
