Expert writing Tips

Best practice

Opt for active voice constructions to improve clarity and conciseness. For example, instead of "the solution was concentrated by evaporation", write "evaporation concentrated the solution."

Common error

Avoid relying heavily on passive voice, which can make your writing sound convoluted and less engaging. Using active voice typically results in clearer and more direct sentences.

Linguistic Context

The phrase "be concentrated by" functions as a passive construction, where an object receives the action of being made more dense or focused. As shown in the Ludwig examples, this construction appears most frequently in scientific contexts.

FAQs

How can I rephrase "be concentrated by" to sound more natural?

Consider using active voice. Instead of "the sample was concentrated by centrifugation", try "centrifugation concentrated the sample". Alternatively, use phrases like "be focused by" or "be intensified by", depending on the intended meaning.

What's wrong with using "be concentrated by"?

While grammatically valid in some contexts, "be concentrated by" often sounds awkward and indirect. Active voice constructions are generally preferred for clarity and impact. The passive construction is not so common in English, and sounds usually artificial, that's why it is suggested to use alternatives.

Is there a difference between "be concentrated by" and "concentrate by"?

"Be concentrated by" is a passive construction, while "concentrate by" (when used as an imperative or infinitive) suggests an action to be performed. Using active voice (e.g., "centrifugation concentrates...") is often more direct and preferable. Alternatively, one can use "focused by".

When is it appropriate to use the phrase "be concentrated by"?

While not always the best choice, "be concentrated by" might be suitable when the agent performing the concentration is unknown or unimportant. However, even in these cases, rephrasing to use active voice or a different passive construction may improve clarity. In most of the cases it is preferable to use phrases like "accumulated through" or other similar forms.
