surface = sur(之上) + face(表面) = 上面的表面→表面，外表
surmise = sur(之上) + mise(放出) = 在下面说出的话→猜测
revival = re(回,翻) + viv(生命) + al(表状态) = 复活
reviv = re(再) + viv(生命) = 再次获得生命→复活，再生
appraisal = ap(加强) + prais(价值) + al(表名词) = 价值→估价；鉴定
approval = ap(加强) + prov(测试) + al(表名词) = 加强测试以证明可行→批准

来源于：听力OFFICIAL52 L3In a fragmented landscape where many populations and habitats are isolated from others, translocations can play an effective role in conservation strategies; they can increase the number of existing populations or increase the size, genetic diversity, and demographic balance of a small population, consequently increasing its chances of survival.
在一个四分五裂的大陆上，不同的种群和栖息地是彼此隔绝的，这时候作为保护措施的物种迁移就起到了重要的作用；他们可以促进动物数量增长，帮助种群规模扩大，增加基因多样性，平衡小种群的数量，最终增加动物的存活率。

所以更弱势的那一种物种要怎么增强自己的存活几率呢？
来源于：听力OFFICIAL36 L6The idea of natural selection is that organisms in a species that have characteristics favoring survival are most likely to survive and produce offspring with the same characteristics.
自然选择的思想是：一个物种里拥有有利于生存的特征的个体更容易生存下来并产生相同特征的后代。
来源于：阅读OFFICIAL36 P3Because the survival of organisms with particular characteristics is favored over the survival of other organisms in the same species that lack these characteristics, future generations of the species are likely to include more organisms with the favorable characteristics.
因为在同一个物种内部，拥有某种特定特征的生物会比没有这种特征的生物的存活更容易。所以这一物种的下一代里，拥有这种特征的个体会变多。

然而，工业污染促进了被黑色煤烟覆盖的叶子上的黑色桦尺蠖的存活。
来源于：阅读OFFICIAL36 P3If natural selection was the explanation, then there should be different survival rates for dark- and light- colored moths.
如果这个理论是正解，那么黑色桦尺蠖和浅色桦尺蠖的存活率应该有区别。
来源于：阅读OFFICIAL36 P3Clearly some environmental factor was responsible for the greater survival rates of dark moths.
显然，一些环境因素导致了黑色桦尺蠖更高的存活率。
来源于：阅读OFFICIAL36 P3But the ants don't absolutely need the caterpillar for survival,cause they can get food from other places right?
但蚂蚁不是绝对需要毛毛虫的生存，因为他们可以从其他地方得到食物吗？

在陆地上鱼鳍从一定程度上可以作为运动的装置，或许能使鱼为了生存从几近干涸的池塘挪动到相邻的有足够水和氧气的池塘。

这些撞击坑的存在告诉我们，一个冰体可以形成并保留其表面的撞击坑。
来源于：阅读OFFICIAL42 P3Now, at that time, the waters the Notothenioids inhabited were still not freezing cold, so the protein didn’t really make a difference as far as the fish’s survival.
在那个时候，由于Notothenioids栖息的海域还没有那么冷，因此这种蛋白并没有那么大的区别，没有达到影响鱼的生存。
来源于：听力OFFICIAL33 L5Many prehistorians believe that farming may have emerged in dependently in several different areas of the world when small communities, driven by increasing population and a decline in available food resources, began to plant seeds in the ground in an effort to guarantee their survival.
很多史前学家认为农业可能是当小型群落迫于不断增长人口和日益减少的食物资源压力而开始在地里种植种子试图维持他们的生计时，进而在世界不同区域独自兴起的。
