suffic = suf(在…下面) + fic(制造) = 使满足；足够…用；合格
sufficient = suf(在…下面) + fic(制造) + ient(形容词) = 从下往上做→足够的
classfication = class(分类) + fic(制造) + ation(表名词) = 把……进行分类→分类,分级
fiction = fic(制造) + tion(表名词) = 制造出的故事→小说
proficient = pro(很多…) + fic(制造) + ient(形容词) = 熟练的；精通的
convenient = con(共同) + ven(来) + ient(形容词) = 共同来的→方便的
abnormally = ab(表否定) + norm(正常) + al(表状态) + ly(表副词) = 异常地
abruptly = ab(离开) + rupt(断裂) + ly(表副词) = 断开→突然断开→突然地
在下面先做好→用的时候足够→充分地
sufficiently
常考释义
By contrast, in the tropics, where each tree species has few, widely scattered individuals, the chance of wind blowing pollen to another individual is sufficiently slim that animals are a safer bet as transporters of pollen.
相比之下，在热带地区，每种树的数量很少，而且散布在各处，靠风把花粉从一棵吹到另一棵的几率太小，这时靠动物来传播花粉就会更保险。

The holes were sufficiently large to serve as nests.
这些洞作鸟巢足够大。
Scientists today have a very good understanding of the physical laws and mathematical equations that govern the behavior and motion of atoms in the air, oceans, and land. Why, then, do we have so much trouble predicting the weather? For a long time, most scientists assumed that the difficulty of weather prediction would go away once we had enough weather stations to collect data from around the world and sufficiently powerful computers to deal with all the data. However, we now know that weather is fundamentally unpredictable on time scales longer than a few weeks. To understand why, we must look at the nature of scientific prediction.
当今的科学家对控制空气、海洋、地中原子的行为和运动的物理定律和数学方程有很好的理解。那么，为什么我们在预测天气方面有如此大的困难呢？长期以来，大多数科学家认为只要我们有数量足够多的气象站来收集来自世界各地的数据和足够强大的计算机来处理所有这些数据，预测天气的困难就会不复存在。然而，我们现在知道，时间跨度超过几个星期的天气基本上是不可预测的。想知道为什么，我们必须看看科学预测的本质。

来源于：阅读OFFICIAL45 P2The empty shell of a snail or clam may be left behind, and if it is sufficiently durable and resistant to dissolution, it may remain basically unchanged for a long period of time.
可能会留下蜗牛或蛤蜊空壳，如果空壳足够坚固并且能抵御分解，就有可能在很长一段时间内基本上保持原样。
来源于：阅读OFFICIAL20 P3Another experiment demonstrated that physical exercise, which was sufficiently vigorous to double the rate of breathing, had no effect on the frequency of yawning.
另一个实验证明，即使是可以让呼吸频率翻倍的剧烈运动对于打哈欠频率也毫无影响。
来源于：阅读OFFICIAL18 P2Yet both chemists were sufficiently farsighted to leave gaps where their analyses of periodic physical and chemical properties indicated that new elements should be located.
然而这两位化学家都极富远见，他们在周期表上留白，对元素物理性和化学性的分析空白处还有新的元素有待发现。
来源于：阅读OFFICIAL16 P2In the northern peninsula the elevation is sufficiently low that the ancient Maya were able to reach the water table at deep sinkholes called cenotes, or at deep caves.
而半岛北部海拔非常低，因此古玛雅人可以由深层排水口或者深洞到达地下水位，这种深层排水口叫做“竖井”。
来源于：阅读OFFICIAL14 P2Probably the most important environmental factor is temperature, for if the growing season is too short and temperatures are too low, tree shoots and buds cannot mature sufficiently to survive the winter months.
或许最重要的环境因素是温度，因为如果生长季节太短并且气温太低，树芽和树苗都无法充分地成长而存活过冬季。
