TPO9-3 The Arrival of Plant Life in Hawaii
Paragraph 4
Many millions of years after ferns evolved (but long before the Hawaiian Island were born from the sea), 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 speed'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 angiosperm the seeds are equipped with gossamer wings, like the dandelion and milkweed seeds. These new characteristics offered better ways for the seeds to move to new habitats. They could travel through the air, float in water, and lie dormant for many months. 9. Why does the author mention a nut, a peach, and a cherry?
○To indicate that some seeds are less likely to survive than others
○To point out that many angiosperms can be eaten
○To provide examples of blooming plants
○To illustrate the variety of coverings among angiosperm seeds
解析：修辞目的题，这几个词所在的句子本身就是个例子，所以往前看，前一句说angiosperm的种子外面有一层种皮，紧接着就说有的外皮是硬的，比如blabla，有的外皮是软的，比如blabla，也就是为了说外皮可以分为不同类别才举的例子，所以D正确，其他的都没说
[4]在蕨类植物进化了好几百万年之后(不过，还是远在夏威夷群岛出现之前)另一种植物开始在地球上进化：种子植物。这是一次惊人的生物进化，种子有一层裹在遗传物质外面的表皮，在表皮里面是一种浓缩了的营养物质。因此，种子物种的成活率相对于那些裸露的孢子大大地提高了。其中一种种子植物——被子植物，包含了所有的开花植物。在被子植物中，种子被另外的一层外皮包裹着。其中的一些表皮很坚硬—就像坚果的外壳—可以提供额外的保护。有一些则很软、诱人，比如桃子或樱桃。还有一些被子植物的种子携带有薄纱一样的翅膀，比如说蒲公英和马利筋的种子。这种特征为种子转移到新的栖息地提供了更好的途径，它们可以通过空气、流水传播并可以保存好几个月。
