举例:
人口数量下降后上升:The number of population decreased andrecovered.
7.波动:这个我就不划了,就像我们的心电图一样。英语中叫fluctuate.
举例:
人口波动:The numberof population fluctuated.
8.达到顶峰:
Peak / reachits summit / reach its zenith
举例:
人口到达了顶峰:The numberof population peaked/ reached its summit / reached its zenith.
上面就是运动性线段的八种趋势了。但是同学们想过没有:上升,下降,波动是存在程度的。所以我们接下来要讨论的是程度的描述方法。程度只有两种:缓慢和陡然。
缓慢的/轻微的:gradually / smoothly / steadily /slightly
陡然的/大幅度的:dramatically/ sharply/ considerably/appreciably/ greatly
举例:
1.人口大幅度攀升: The number of populationmounted dramatically.
2.人口轻微下降: The number of populationdecreased slightly.
3.人口逐渐下降: The number of populationdecreased gradually.
好了,我们现在已经说了两个范畴了,这个两个范畴可以帮你搞定任何线段组的描述。
