1、【寫在最前面，以免你看不見】首先是 Team work。什么時(shí)候來 teamwork 一下。你要是覺得來 caiomario 不方便，可以到 fortino 來找你 teamwork，沒問題。第二是這個(gè) work 文檔先當(dāng)于一個(gè)講稿，是從書上/網(wǎng)上 經(jīng)過篩選！不是簡單摘抄，是篩選，出來之后的稿。所以既要有標(biāo)題，也要有正文。之后從稿子中再精煉出關(guān)鍵字、關(guān)鍵句放在 ppt 上。每個(gè)人，能通過對照 ppt 上的關(guān)鍵字，把關(guān)鍵字背后的“正文”內(nèi)容大致的說出來（不是背出來）。同時(shí)你的內(nèi)容要有“點(diǎn)”，不要寫成文章。要把文章寫成“點(diǎn)”。Liquid-based raprototyMost liquid-ba
