这个图形比较奇怪，大家可以跟着我划一下：线段前面是向下的，后面是平的，在表示这个平的时候我们就不可以使用remain steady了，我们要使用的结构是bottom out.
举例：人口下降后保持平稳：The number of population decreased and bottomed out.
5.上升后保持平稳：
这个图形和上面那个类似，不过前面部分是上升的，后面部分是平的.前面的上升我们就不用说了，但是在上升以后保持平稳，我们需要使用level off.
举例：人口上升后保持平稳：The number of population mounted and leveled off.
6.复苏：
前面下降了以后，然后就上升了，这两条线段的连接点就叫复苏.英语中表达为recover
举例：人口下降后复苏：The number of population decreased and recovered.
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 number of population fluctuated
8.达到顶峰：
peak/reach its summit/reach its zenith
举例：人口到达了顶峰：The number of population peaked/reached its summit/reached its zenith.
二、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/
举例：
人口大幅度攀升/逐渐下降：The number of population mounted dramatically/ decreased gradually.
三、介词的使用
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.紧接下来我们要讨论的是如何将线段组与数据进行连接.非常简单，注意如下的介词使用.
(一)remain steady/stay stable/level off/bottom out/peak/reach its peak/reach its zenith 后面需要使用的是at.
举例：
1. 人口在500万上保持平稳：The number of population remained steady at 5 million.
2. 人口在800万时到达了顶峰：The number of population peaked at 8 million.
3. 下降后，人口在400万保持平稳：After decreasing, the number of population bottomed out at 4 million.
4. 上升后，人口在700万保持平稳：After mounting, the number of population leveled off at 7 million.
(二)上升/下降后面使用to(到)和by(了)
举例：
1. 人口下降到200万：number of population decreased to 2 million.
2. 人口下降了200万：number of population decreased by 2 million.
(三)recover的后面大家需要使用的是from
举例：
人口在200万时开始复苏：The number of population recovered from 2 million.
(四) fluctuate的后面大家需要连接between...and…
举例：
人口在2和100亿之间波动：The number of population fluctuated between 2 and 10 billion.
