　　托福阅读词汇题：dormant

　　【Paragraph 4】Many millions of years after ferns evolved (but long before the Hawaiian Islands were born from the　se○, another kind of flora evolved on Earth: the seed-bearing plants. This was a wonderful biological invention. The seed　has an outer coating that surrounds the genetic material of the new plant, and inside this covering is a concentrated　　supply of nutrients. Thus the seed’s chances of survival are greatly enhanced over those of the naked spore. One type of　seed-bearing plant, the angiosperm, includes all forms of blooming vegetation. In the angiosperm the seeds are wrapped　　in an additional layer of covering. Some of these coats are hard–like the shell of a nut–for extra protection. Some are soft　　and tempting, like a peach or a cherry. In some angiosperms the seeds are equipped with gossamer wings, like the　　dandelion and milkweed seeds. These new characteristics offered better ways for the seed to move to new habitats.　They could travel through the air, float in water, and lie dormant for many months. (The Arrival of Plant Life in Hawaii)
