My friend Richard went far to work, so he asked me to take care of his yard in the mountains. He worked hard and often kept the yard_______without any grass. But I was too lazy to sweep the fallen leaves, and I_______pluck (拔) grass, allowing it to grow rapidly. In the early_______, in March, the leaves were green and soft. A month later, when the leaves spread quickly, I discovered they were like wild orchids (兰花) in the forest.

As the summer came, the "grass" really flowered. The flowers looked like those forest orchids,_______they were yellow, unlike those purple or brown red forest orchids. I picked one flower, then went to find a friend who studied_______.As soon as my friend saw it he asked me_______I picked it. "It's amazing!" He_______explained, "This kind of orchid is hard to find. Now it is worth at least 10,000 dollars each."

I told the good news to Richard. He was_______. After a while he said gently, he saw the orchid in the yard every year, but he thought it was common grass, so he always plucked it. He said, "If I could_______, it would flower a few years before." Yes, all of us might miss some rare(稀有的) orchids in our own lives. We don't give them the time to flower to prove their value.

Give the "grass" time to flower and give everybody a________to prove his value. Don't pluck a leave of any "grass" or negate (否定) a person rudely and how many "rare orchids " we will get in our lives!
