Be sure that a main verb isn’t missing from your sentences or dependent clauses.
not this: My boyfriend very ambitious.
but this: My boyfriend is very ambitious.
not this: Sylvia cried when the hero in the movie.
but this: Sylvia cried when the hero in the movie died.
Be sure to put the -s on present-tense verbs in the third-person singular:
not this: He
run in the park every morning.
but this: He runs in the park every morning.
not this: The concert
start at 9:00 p.m.
but this: The concert starts at 9:00 p.m.
Be sure to put an -ed ending on the past-participle form of a verb when necessary. There are three main forms of a verb:
present: Today I walk.
past: Yesterday I walked.
past participle: I have walked. He has walked.
The past-participle form is also used after were, was, had, and has:
not this: He has
call me every day this week.
but this: He has called me every day this week.
not this: My neighbour was
surprise by the sudden storm.
but this: My neighbour was surprised by the sudden storm.
Do not add -ed endings to infinitives. An infinitive is the verb form that uses to plus the present form of the verb:
infinitives: to consider, to obey
not this: Dean wanted me to
considered the proposal.
but this: Dean wanted me to consider the proposal.
not this: I taught my dog to
but this: I taught my dog to obey commands.
