     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
    仙人掌通常生长在沙漠里。它通身绿色。它的茎是椭圆形的，并且全身长满刺，实际上它们身上的刺是它们的叶子。叶于长成这种形状是为了阻止它们身体内的水分蒸发到热而干的空气里。仙人掌长着长长的根，它们把根深深地扎入地底下以便从更深层的土中吸收水分。
    它们一般开小而白的花。尽管它们在沙漠里被忽视，但是它们从不放弃开花并且默默地点缀着沙漠。
