　　非洲草原上的尖毛草，是非洲大地上生长的最高的毛草，有“草地之王”的美称，但是它的生长过程十分怪异。在最初的半年里，它几乎是草原上最矮的草，只有一寸高，人们甚至看不出它在生长，那段时间，草原上的任何一种野草，长得都要比它旺盛，没有人能看出尖毛草会是今后的“草地之王”！ 但在半年后，在雨水到来之际，尖毛草就像是被施了魔法一样，以每天一尺半的速度向上疯长，三五天的时间，它便会长到一米六至两米的高度。

科学家的研究表明，尖毛草其实一直在生长，但它不是在长身体，而是在长根部。在长达六个月的时间里， 尖毛草的根部长得超过了28米，无声无息地为自己的将来做准备。一棵草，竟然有28米以上的根，这是多么罕见的现象。当蓄积了足够的营养和能量后，尖毛草便会一发而不可收拾，在短短几天的时间里，一下子长成了草地之王。

People in the United States honor their parents with two special days: Mother’s Day, on the second Sunday in May, and Father’s Day, on the third Sunday in June.

Mother’s Day was proclaimed（宣告）a day for national observance by President Woodrow Wilson in 1915. Ann Jarvis from Grafton, West Virginia, had started the idea to have a day to honor mothers. She was the one who chose the second Sunday in May and also began the custom of wearing a carnation（康乃馨）.

In 1909, Mrs. Dodd from Spokane, Washington, thought of the idea of a day to honor fathers. She wanted to honor her own father, William Smart. After her mother died, he had the responsibility of raising a family of five sons and a daughter. In 1910, the first Father’s Day was observed（庆祝）in Spokane. Senator Margaret Chase Smith helped to establish Father’s Day as a national commemorative day, in 1972.

These days are set aside to show love to parents. They raise their children and educate them to be responsible citizens. They give love and care.

These two special days are celebrated in many different ways. On Mother’s Day people wear carnations. A red one symbolizes a living mother. A white one shows that the mother is dead. Many people attend religious services to honor parents. It is also a day when people whose parents are dead visit the cemetery（墓地）. On these days families get together at home, as well as in restaurants. They often have outdoor barbecues for Father’s Day. These are days of fun and good feelings and memories.
