一、写作是人脑深度思考的过程

    正因为人都是有思想懒性的，写作才显得尤为重要，它促进了我们的思考。 在写作过程中，一些观点可以跃然纸上，而这些观点在平日里仅仅是浮光掠影般转瞬即逝

二、好文章是要经过反复修改的

    经典的，经得起时间考验的文章绝对不是一气呵成的。法国的福楼拜，莫泊桑，俄国的托尔斯泰安，日本的小泉八云都是以美文著明，这些作家的著作都是经过反反复复的修改，不厌其烦的修改，最后的文字才能像《红楼梦》那样经历几百年屹立于文学之林。

三、科研写作虽然和普通文学写作有区别，但是和文化作品一样，要有咬文嚼字浸于迂腐的精神

    印象很深的是那次黄老板带我分析他写的基金，字字珠玑，句句话都是我想写却写不出来的（至少5年内写不出来）但是他和我说了一句：“看到了吗？我这个基金还被ranked at the bottom, it is never all set!”

    永远记住好的文字远胜过图片和影视带来的冲击效果，它是直接用语言的形式和读者交流的，那么你一定要确保怎么不让你的读者confused，怎么让他们被你“牵着鼻子走”，让他读完每一句都会对你的下一句话感兴趣

Guideline for Scientific Writing:

1. TENSE is very important, When it is a statement or a fact or a truth, such as
   (1) our results show XXXX;
   (2) Our findings suggest XXX
   Using PRESENT tense

2. When it is an experimental observation, such as
(1) We found XXX;
(2) The axenic flies appeared to feed on different fruits more randomly
(3) XXX developed faster and produced more offspring

3. Future work section
You want to describe the purpose instead of which tools or method you would apply.

4. Writing an abstract is very different from writing a grant
In grant, you need to show your preliminary data and illustrate why you need the money!
However, in an abstract, try your best you convince the readers.
Do NOT be ambiguous.

5. Hypothesis must be aligned with objectives
if the objective is: Test the aging effect in susceptibility of covid-19
Then, the corresponding hypothesis would be like: Older people is more vulnerable to get infected
Your hypothesis should NOT be like this: The immune system is weeker in older people….

再举个例子，假如我的研究目的是：探究喝酸奶对肠道菌群丰富度的影响 我的假说可以是：喝酸奶提高肠道菌群丰富度，或者喝酸奶对肠道菌群丰富度没影响 不能这样假说：喝酸奶有益健康，并伴随着肠道乳酸杆菌的丰富度增加 这样假说对应的研究目的是什么呢？ 大概应该是这样的：Characterize the effect of dietary yogurt in the interplay between Lactobacillus richness and human fitness…..
