在非洲的热带草原上,生长着一种尖毛草。在最初生长的半年时间里,尖毛草是草原上最矮的植物。在那段时间里,草原上任何一种野草都比它长得高,比它长得茂盛。但是,半年过后,在雨水到来之际,尖毛草像被施了魔法一样,一发不可收拾,以每天0.5米的速度向上疯长,几天过后,它就会长到2米的高度,成为非洲草原上的“草地之王”。人们对尖毛草这种生长现象非常难理解,开始 In the savannah of Africa, there is a kind of sharp hair grass. In the first half of the year, T. cuspidate was the shortest plant on the grassland. During that time, any kind of wild grass on the grassland grew taller than it did, and grew stronger than it. However, half a year later, when the rain came, the spikygrass was as if it had been enchanted. It was out of control and grew at a speed of 0.5 meters a day. After a few days, it would grow to a height of 2 meters and become “King of the Grass” on the African grasslands. It is very difficult for people to understand the growth phenomenon of T. cuspidata.
