4.5 Using accurate tense sequence
When you want your sentences to deliver message about actions, occurrences, or states that occur over time, you must depend on verb tenses in sequences. These sequences often include more than one verb. Using accurate tense sequences, that is, showing time relationships correctly is important for clear communication.
4.6 When independent –clause verb is in the simple resent tense, for the dependent-clause verb:
Use the present tense to show same –time action.
The director says that the movie is a tribute to Chaplin.
I avoid shellfish because I am allergic to it.
Use the past tense to show earlier action.
            I am sure that i deposited the check.
Use the present perfect tense to show (I)a period of time extending from some point in the past to the
Present-often accompanied by for or since- or (2) an indefinite past time.
They say that they have lived in Canada since 1979.
I believe that I have seen that movie before.
Use the future tense for action to come.
            The book is open because I will be reading it later.
4.7 When independent-clause verb is in the past tense, for the dependent-clause verb:
Use the past perfect tense to show earlier action.
            The Sprinter knew that she had broken the record.
Use the present tense to state a general truth.
Christopher Columbus discovered that the world is round.

Use the past tense.
The sugar plate had become moldy since I poured it last week. Sugar prices had already declined when artificial sweeteners first appeared.
4.8 When the independent-clause verb is in the future tense, for the dependent-clause verb:
Use the present tense to show action happening at the same time.
You will be rich if you win the prize.
Use the past tense to show earlier action.
You will surely win the prize if you remembered to mail the entry form
Use the present perfect tense to show future action earlier than the action of the independent –clause verb.
The river will flood again next year unless we have built a better dam by then.

4.9 When the independent-clause verb is in the future perfect tense, for the dependent-clause verb:
Use either the present tense or the present perfect tense.
Dr. Chang will have delivered 5,000 babies by the time she retires.
Dr. Chang will have delivered 5,000 babies by the time she has retired.

When an independent-clause verb is in the future tense, do not use a future-tense verb in the dependent clause.
No       The River will flood again next year unless we will build a better dam.
YES    The River will flood again next year unless we build a better dam.
[Dependent-clause verb have built is the present tense.]
YES    The River will flood again next year unless we have built a better dam by the.
            [Dependent-clause verb have built is in the present tense]

Tense sequences that include INFINITIVES or PARTICIPLES must be correct. The present infinitive can name of describe an activity or occurrence coming either at the same time or after the time expressed in the MAIN VERB.
To buy comes at a future time, Hope is the main verb, and its action is now
I hoped to buy a used car.
Hoped is the main verb, and its action is over.
I had hoped to buy a used car.
Had hoped is the main verb, and its action is over.

The present participle (a verb’s –ing form) can describe action happening at the same time driving his new car, the man smiled. [The driving and the smiling happened at the same time.]
To describe an action that occurs before the action in the MAIN VERB, use the PERFECTIVE INDEFITIVE (to have gone, to have smiled); the PAST PARTICIPLE: or the PRESENT PERFECT PARTICIPLE (having gone, having smiled),
Candida claimed to have written fifty short stories in college.
First Candida wrote ; then she claimed

Pleased with the short story, Candida mailed it to several magazines.
First Candida was pleased ; then she mailed
Having sold one short story, Candida invested in a word processor,
First Candida sold a story; then she bought a word processor.

Voice refers to a verb’s ability to show whether a SUBJECT acts or receives the action named by the verb. English has two voices: active and passive. In the active voice, the subject performs the action.
Most clams live in salt water. [The subject “clams” does the acting; “clams live”.]
They burrow into the sandy bottoms of shallow waters. [The subject “they” does the acting; “they burrow”.]
In the passive voice, the subject is acted upon, and the person or thing doing the acting often appears as the OBJECT of the PRESPOSITION by. Verbs in the passive voice add forms of be and have, as well as will as’ auxiliaries to the PAST PARTICIPLE of the MAIN VERB.
Clams are considered a delicacy by many people.
The subject “clams” is acted upon by people, the object of the preposition “by”
They are also admired by crabs and starfish.
The subject “they” is acted upon by crabs and starfish, the objects of the preposition “by”

When you write, your decisions about AUDIENCE and PURPOSE should influence the voice that you choose for a sentence. Misusing voice usually creates problems of writing style rather than problems of incorrect grammar. For ways to identify and correct confusing SHIFTS in voice.
Write in the active voice, not the passive voice, except to convey special types of emphasis Because the active voice emphasizes the doer of an action, active constructions are more direct and dramatic. Because the active emphasizes the doer of an action, active constructions are more direct and dramatic. Active constructions often use fewer words than passive constructions and are therefore more concise. Any sentence in the passive voice that expresses the doer of the action can easily be converted to the active can easily be converted to the active voice.

African tribal masks are often imitated by western sculptors.
Western sculptors often imitate African tribal masks.

The passive voice, however, does have some usages. If you learn why they are, you can use the passive to advantage.
Using the passive voice when the doer of the action is unknown or unimportant
When no one knows who or what did something, the passive voice is useful.
The lock was broken sometime after four o’clock.[who broke the lock is unknown],
In 1889, the year I was born, a peace conference was held at The Hague.[The doers of the action—holders of the conference –are unimportant.]
Using the passive voice to focus attention on the action rather than or the doer of the action
The passive voice emphasized the action, while the active voice focuses on the doer of the action. In a passage about important contributions to the history of science, you might want to emphasize a doer by using the active voice.
ACTIVE                      Joseph Priestly discovered oxygen in 1774.
But      In a passage summarizing what is known about oxygen, you may want to make oxygen, rather than Priestley, the sentence subject, doing so requires a passive-voice verb.

PASSIVE       Oxygen was discovered in 1774 by Joseph Pristley
PASSIVE       The unsigned letter was sent before it could be retrieved from the mailroom [Emphasis is on events, not on doer of the action.]
ACTIVE:         The postal clerk sent the unsigned letter before I could retrieve it from the mail room [Emphasis is on the people rather than the actions.
