I/ Passive forms :
We use the passive forms for reasons of style and of clarity , as well as of meaning . Mostly the rules of passive formation are straightforward, but it needs to be that certain words and structure cannot be used in this passive.

The passive of an active tense is formed by putting the verb and adding the past participle of the active verb .The subject of the active verb becomes the agents of the passive verb. The agent is very often not mentioned .When it is mentioned it is preceded by By and placed at the end of the clause:
-This tree was planted by my grandmother.
Passive voice
Uses of the passive
The passive is used:
When it is not necessary to mention the doer of the action as it is obvious who he is/was/will be:
-The rubbish hasn’t been collected.
-Your hand will be X-rayed.
When we don’t know , or don’t know exactly , or have forgotten who did the action:
-The minister was murdered./My car has been moved!
When the subject of the active verb would be “people”
-He is suspected of receiving stolen goods. (People suspect him of….).
When the subject of the active sentence would be the indefinite pronoun one: One sees this sort of the advertisement everywhere would usually be expressed:
-This sort of advertisement is seen every where.
In colloquial speech we can use this indefinite pronoun and active verb :
-You see this sort of advertisement everywhere.
But formal English requires one + active verb or the more usual passive form .
When we are more interested in the action than the person who does it:
The house next door has been bought (by a Mr James)
The Passive may be used to avoid an awkward or ungrammatical sentence. This is usually done by avoiding a change of subject :
When we arrived home a detective arrested him .
Would be better expressed :
When he arrived home he was arrested(by a detective).
The passive is sometime preferred for psychological reasons. A speaker may use it to disclaim responsibility for disagreeable announcements

Used is the past tense of a defective verb which has no present tense.
Affirmative: used to + inf. for all persons.
Interrogative :Did you/he/they use to + inf.?
Negative: S + didn’t use to + inf.
Used to is followed by the full infinitive .
Used to
Use:
“Used to” is used to express the discontinued habit or the situation which contrasts with the present
Note: Used is not formally stressed , but it can be stressed if the speaker wishes to emphasize the contrast between the past and the present.
Used as an adjective: To be/become/get used to:
Used can also be an adjective that means ‘accustomed’. It is then preceded by be ,become or get in any tense and followed by the preposition To + noun/pronoun or gerund:
I’m used to working in a noisy room .
I’ll get used to writing emails by yahoo.
I am used to…….etc is a psychological statement .
Do not confuse with Be used to and used to
Be used to + V-ing or noun phrase.
Used to + bare infinitive.
