妈妈养了一盆仙人球,它的形状是椭圆形的,看上去好像一个大菠萝。但是它与菠萝有很大不同,它的身体外部,一道鼓出来,一道凹进去,很是匀称,酷似人们洗衣服用的搓衣板。在每一道鼓出来的地方,均匀地分布着一排排小疙瘩,每个小疙瘩上面长着十几根一厘米来长的小刺,又细又硬,根根向外伸展着,好像在保护着自己的身体。 Mom raised a pot of cactus, its shape is oval, looks like a big pineapple. But it is very different from pineapple, it's body outside, a drum, a concave, very symmetry, just like people wash clothes washboard. In each drum out of place, evenly distributed rows of small lumps, each small lump above a dozen centimeters long spines, thin and hard, root outstretched, as if Protect your body.
