"Experimental work is by definition a journey into the unknown, fraught with detours and dead ends, but all such obstacles are basically irrelevant from a scientific standpoint. Look upon your dissertation--as you would any other research report--not as a memoir documenting and explaining your every activity, but instead as a proclamation of a set of new insights. How you achieved your results may perhaps play some role in your mentor's appraisal of your efforts, but otherwise it will be of interest only to the extent that certain intimate details may be critical from a methodological standpoint."
" Another reason on why this paper is long and somewhat distracting is that you frequently use words such as "It was found that" (p. 2), "It is worth noting that…" (p. 7), "It was observed that …" (p. 8), "It was observed that…" (p. 9), "It was noted that…" (p. 12), "We observed that…" (of course, it's you who make the observation!), "It was noticed that" (p. 13), "It was interesting to see that…", "It was observed that…", "It was concluded that" (p. 15), "It was found that (p. 17)".”
" Throughout the text, for two or three times (e.g., line 11 of p. 12), the authors always wrote "it is not surprising that...". The intention of the authors was to justify their data, to say that their data are "normal". However, if the authors always say "it is not surprising", why should the reader care unsurprising results? Isn't it better to use "it is justified that..." or "it is reasonable that..."?”

"Avoid sentences that are unnecessarily complex and entangled, or run on interminably. Problems of the latter sort often have their origin in 'that' constructions:
Example 4-8: It is well established that... (of course!)
One can assume that... (presumably!)
From this result it follows that... (= thus, hence, therefore)
We must not take it for granted that ... (= unlikely)
Note that the examples above are followed in parentheses by a word or words with the potential to head the offending sentence off in a more promising direction. Sometimes a single well-chosen word is able to replace an entire phrase, simultaneously eliminating the need for at least one punctuation mark. Equally important, a remodeling in this sense often permits the true message of the sentence to migrate from an awkward subordinate clause to the main clause, where it belongs."
"Hype tends to creep in naturally under the pen. A good characterization of hype is overindulgence in adjectives. Just like overindulging in sweets leads to obesity, accumulating adjectives bloats a text, makes it bottom-heavy and turns it into failure." p. 26, "I am not telling you to shy from waving your flag. Advertising is definitely involved in the writing of an introduction, but the softest of touches is needed. One-upmanship can be very distructive."

"Do not overstate. When you overstate, readers will be instantly on guard, and everything that has preceded your overstatement as well as everything that follows it will be suspect in their minds because they have lost confidence in your judgment or your poise. Overstatement is one of the common faults. A single overstatement, wherever or however it occurs, diminishes the whole, and a single carefree superlative has the power to destroy, for readers, the objective of your enthusiasm."
仔细读Chemical Communications杂志，发现的常见主动句是"Herein, we report...", "We propose that..", "To further check/demonstrate this hypothesis, we designed further experiment by...", "We believe that...", "To see whether ... is due to..., we did further experiments...".可见主动句有几种，第一种是在引言中说我们发现了什么；第二中是说我们认为什么，是提建议的；第三种是说为了证明什么，我们做了进一步的实验。有了这些主动句，文章就更加神采飞扬了。

"We urge you in general, as often as you can, to incorporate lively verbs into your writing. Trt to take as much advantages as you can of sentence structures rooted in the active voice, which is the most welcoming environment for 'words of action'. Few world dispute the assertion, however, that passive constructions rarely contribute in a positive way to descriptive prose."
p. 84, "It has become increasingly common in published scientific works to encounter examples of first-person verb forms, which unquestionably add life to their surroundings. Note that this development carries an important inplication, however: the authors responsible are suggesting in a subtle way that the parties involved in conducting a scholarly investigation may themselves play a more than passive role:
Examples 10-7 ... This being the case, we elected to...
... We therefore separated (introduced, heated)..
... In the hope of conferring antimalarial activity on pharmaceutical precursors, we prepared..."

"In general, paragraphs should probably not exceed about a third of a page, equivalent to perhaps four to eight sentences. Paragraphs make an important contribution to the intellectual structure of a document, quite apart from the fact that they break up an otherwise 'endless stream of text', which is unsightly and inflicts too much organizational burden on the reader."
"Structuring a document as a series of coherent paragraphs forces the author to sort out and present his or her thoughts in a logical fashion. That is to say, a proper paragraph is dedicated to exploring a single subject or thought, which in principle could easily be articulated in a brief descriptive title."
"The first sentence in every paragraph warrants special attention. One of its principle functions is to let the reader know what the ensuing discussion is about, for which reason it is often referred to as the "topic sentence". The corresponding topic is then pursued in sentences that immediately follow, with the final sentence in the paragraph so crafted that if supplies a bridge to the next paragraph."

"Near the end of your discussion you may want to be bold and suggest interesting avenues for future exploration: promising approaches to resolving remaining uncertainties, ideas for broadening the scope of a methodology you have developed, or ways of possibly refining your results. If so, be sure the suggestions you make are concrete."
