2. The monthly fee of TV is 20% less than the Combination.

Argument：
Cell phone manufacturing always purchase the expensive metals, such as gold, silver and so on. Since last decades, the prices of these metals have been risen or fallen dramatically, and the forecast of the growth consumption of the cell phones look strong. The company require huge-volume of metals. Purchasing large quantities of the metals might lock the saving and garentee the profits.

Reading有个讲H蝴蝶跟P职务的共存生物进化关系
第一段是解释以下那个生物共存关系
第二段就说那个蝴蝶是靠植物的chemistry什么的决定产卵
第三段是讲但是有H蝴蝶，看到植物上有别的蝴蝶产卵就不产卵了；所以P植物就自动产生一些类似卵的东西，个所以H蝴蝶就在那上面产卵了。

之前的回忆过的我就不重复说啦！
还挺多的是之前有看到过的！！
