Grammatically Correct: The writer's essential guide to punctuation ...

GRAMMATICALLY CORRECT
WORD IT AS: We asked all participants to speak openly about their
feelings.
This strategy is very popular and often works smoothly and unobtrusively,
but should be avoided if the plural sounds contrived or
unlikely. There are many cases where a plural rather than a singular
noun simply would not convey the same sense, particularly if you
wish to emphasize the individuality of the actions under discussion.
Bear in mind the caution about your words coming through as
"general and diffuse." And, as discussed previously, don't try to get
around the issue by using they as a singular pronoun.
USING THE INDEFINITE PRONOUN ONE
In some circumstances, one can substitute one for he. (This pronoun
is also sometimes used as a substitute for the first or second person,
as discussed on page 258.) Use of this pronoun usually carries an
implication that the writer and reader belong to the same group or
share some relevant characteristic or interest; in a sense, it conveys
the idea of "you or I." For example, as a writer, one could work it
into a book addressing other writers. (Is one making oneself clear?)
Thus, for instance, in an article aimed at physicians,
INSTEAD OF: Clinical judgment involves the physician making use of
his experience, as well as his knowledge of the particular patient.
WORD IT AS: Clinical judgment involves making use of one's experience,
as well as one's knowledge of the particular patient.
This approach is usually inappropriate if the intended readers
would not be able to relate to the group or activity under discussion.
Also, overuse of "one" can make your writing sound a bit stuffy.
USING THE SECOND PERSON
In certain types of writing, you can use you in order to avoid the
third person-as here. This form is appropriate for genres that
address the reader directly, such as instruction manuals. For
example:
300
INSTEAD OF: The reader should familiarize himself with these terms
before proceeding.
WORD IT AS: Familiarize yourself with these terms before proceeding.
