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（1） 　　without any grass． But I was too lazy to sweep the fallen leaves，and I（2） 　　pluck（拔）grass， allowing it to grow rapidly． In the early （3） 　　， 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．

He（7） 　　explained， "This kind of orchid is hard to find． Now it is worth at least 10，000 dollars each． "
