小作文：
    兩個(gè)時(shí)代的cutting tools made by small pieces of stone
    上邊的兩幅圖是描述1.4million year 的TOOL A的，左邊是front view正面圖，右邊的是側(cè)視圖和背視圖。下面的兩幅是800000年前的 tool B ，也是左邊的是正面圖，右面的是側(cè)視圖和背視圖。TOOL A比較粗糙，TOOL B打磨的比較好。
    Main Features:(
    外形比較： 根據(jù)front and back view近年的切割工具比遠(yuǎn)年的切割工具要size“大”，quality“經(jīng)過(guò)更多的打磨和處理”
    根據(jù) side view 遠(yuǎn)古的比近年的工具要“薄”，換句話(huà)將更“利于切割”
    功能：可以用來(lái)“砍一些樹(shù)枝”，“砍草”，“切割動(dòng)物的尸體”和“皮毛”
    趨勢(shì)（時(shí)間）：從古到今，工具的制作水平有了很大的提升。
    Organization:
    1st 介紹這兩張圖表的背景 + 功能
    2nd 細(xì)節(jié)一
    3rd 細(xì)節(jié)二(
    4th 總結(jié)說(shuō)明這些圖表的一種具體的趨勢(shì)
    Models(范文):
    Both diagrams show the cutting tools that were made by a small piece of stone 1.4 million years ago and 0.8 million years ago. Obviously, they are used for breaking off branches, cutting grass or choppinganimal bodies and skins.
    Specifically, the size of 1.4-million-year-ago tools, in the front and back view, is much smaller than that of 0.8-million-year-ago ones, and the surface of the latter is far smoother than that of the former.
    However, we can clearly see that the tools made 1.4 million years ago seem to be eventhinner than the ones produced 0.8 million years ago in the side view.(
    According to all of information involved, it can be discovered that there is a very noticeable change in cutting tools that were done in ancienttime. In other words, humans had made a lot of progressin producing tools in the period of 0.6 million years
