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.
仙人掌通常生长在沙漠里。它通身绿色。柄是椭圆形,它浑身带刺。实际上它们身上的刺是它们的叶子。这样的树叶仅仅是因为他们可以阻止水从他们的身体蒸发进入炎热和干燥的空气。仙人掌的根很长,他们自己的根深入到土地,使他们能够更深得到水,土。
他们总是有白色的小花。尽管它们在沙漠里被忽视,但是它们从不放弃开花,默默地点缀着沙漠。
