1. 听写包答案:
The third adaptive strategy is to avoid the drought conditions altogether.
Yes! There are plants that do this: annual plants.
An annual plant will mature and produce seeds in a single season that will become the next generation of annual plants.
In desert conditions, annual plants grow in the fall or spring to avoid the heat of summer and the cold of winter.
Of course, these plants could face a serious problem if a particular fall or spring happen to be very dry.
They would have difficulty growing and could die before producing seeds.
But they have a mechanism to prevent one year of low rainfall from wiping them out.
Not all seeds an annual plant puts out will grow the following year.
Some seeds remain dormant in the ground for several years.
It’s a type of insurance that protects the annual plants from a season of poor growing conditions, of unfavorable weather.
第三个适应策略就是完全避开干旱的环境。
是的,确实有植物会这么做,它们就是一年生植物。
一年生植物仅在一季中就能成熟并产籽,这些籽会成为下一代的一年生植物。
在沙漠环境中,一年生植物会在秋天或春天生长,以避开夏季的酷热和冬季的严寒。
当然啦,如果某一年的秋天或春天碰巧特别干旱的话,这些植物会遇到很严重的问题。
它们会无法生长,而且可能会在能产籽之前就死去。
但是它们有一个机制,能够防止一年的低降雨量导致它们灭绝。
不是所有一年生植物散出的种子都会在来年发芽的。
一些种子会在地上保持休眠状态好几年。
这是一种从生长环境不好的一季,从不利的天气中保护这种一年生植物的保险。
2.阅读包答案:
从共性中过滤掉特性.也许我们就能理解复杂的文化行为是怎么产生的,以及是什么在进化或认知方面引导了这种行为。
3.习作包答案:
Thrills,indeed,are merely an amusement,and their effect vanishes as quickly as the effect of a game of cards.Those who enjoy life most enjoy thrills least.Or it might be nearer the truth to say that they are least dependent on thrills for their happiness.The autobiography of the happiest man would not be record of sensational experiences.Charles Lamb's tenderest essay was called Old China,not Murderers I Have Met.
