$\huge{\bf{\green{Simple \:Past\: Tense}}}$

$\bf{\underline{\underline {STRUCTURE}}}$

For active voice, we write:

$\bf{\blue{subject \:+ verb\: (past\: tense)}}$ .

$\bf{\underline{\underline {FORMATION}}}$

$\bf{\underline{1. Affirmative\: sentences}}$

We use past tense with all subjects $\blue{(I,\:we,\: you,\:he,\:she ,\:it,\:they)}$ .

$\bf{\red{Examples:}}$

• Sarita $\blue{met}$ me at the mall yesterday.
• We $\blue{crossed}$ the road in a hurry.

$\bf{\underline{2. Negative\: sentences}}$

We place $\blue{did \:not}$ after the subject and use root form of the verb.

$\bf{\red{Examples:}}$

• Chetan $\blue{did \:not\: appear}$ for the unit test.
• They $\blue{did \:not \:meet}$ me yesterday.

$\bf{\underline{3. Interrogative\: sentences}}$

We place $\blue{did}$ before the subject and use root form of the verb after the subject.

$\bf{\red{Examples:}}$

• $\blue{Did}$ you $\blue{visit}$ the Book Fair last week?
• Where $\blue{did}$ Roma $\blue{keep}$ the file?

$\bf{\underline{\underline {USES}}}$

1. The past indefinite ($\blue{simple\: past}$) tense is used to express an action that took place at some point of time in the past.

$\bf{\red{Examples:}}$

• I $\blue{wrote}$ the mail yesterday.
• He $\blue{went}$ to Europe last month.

2. It is use to express an action that took place over a period of time in the past.

$\bf{\red{Examples:}}$

• I $\blue{lived}$ in a hostel in Mussoorie from 2001 to 2010.
• I $\blue{spent}$ my childhood in Mumbai.

3. Like the simple present tense, this tense can be used to refer to habitual actions and states.

$\bf{\red{Examples:}}$

• Grandmother often $\blue{told}$ us interesting stories.
• My grandfather $\blue{liked}$ a cup of hot milk at bedtime.

4. It is used in conditional sentences to express an improbable condition.

• If I $\blue{knew}$ him, I would approach him for help.
• If I $\blue{had}$ money, I would buy a cottage in the mountains.

$\huge{\bf{\green{Past\:Perfect\:Tense}}}$

$\bf{\underline{\underline{STRUCTURE}}}$

For active voice, we write:

$\bf{\blue{subject\: + \:had \:+ \:past\: participle}}$ .

$\bf{\underline{\underline {FORMATION}}}$

$\bf{\underline{1. Affirmative\: sentences }}$

We use $\blue{had}$ and third form of the verb with all the subjects.

$\bf{\red{Examples:}}$

• I $\blue{had\:already}$ met the manager.
• The train $\blue{had\: left}$ before I reached the station.

$\bf{\underline{2. Negative\: sentences }}$

We use $\blue{not}$ after $\blue{had}$.

$\bf{\red{Examples:}}$

• He $\blue{had not applied}$ for a job here till we told him to.
• Mother $\blue{had not left}$ for the market when the postman arrived.

$\bf{\underline{3. Interrogative\: sentences}}$

We put had before the subject.

$\bf{\red{Examples:}}$

• $\blue{Had}$ you $\blue{read}$ the contract before you signed it?
• $\blue{Had}$ she $\blue{found}$ a new job by that time?

$\bf{\underline{\underline {USES}}}$

1.The past perfect tense is used to denote an action which had been completed at some point in the past before another action took place. Therefore, it is generally used along with the simple past tense .

$\bf{\red{Examples:}}$

• The message came after he $\blue{had\: left}$ the office .
• The chief guest $\blue{had\: inaugurated}$ the library before we reached the school.

2. It is used with such verbs as hope, expect, think, mean, suppose, want, etc., to suggest that an expected past action did not take place.

$\bf{\red{Examples:}}$

• We $\blue{had \:hoped}$ that the weather would remain pleasant during our journey. (but it didn't)
• I $\blue{had\: thought}$ that I would be able to finish the project before the end of this month. (but I couldn't)

3. It is used to express an unfulfilled wish or condition in the past.

$\bf{\red{Examples:}}$

• I wish I $\blue{had \:shared}$ my problems with my parents.
• If she $\blue{had \:approached}$ me, I would have advised her to work harder.

4. This tense is used when from a specific time in the past, we look backward at an event that took place earlier in the past.

$\bf{\red{Examples:}}$

• By 8 a.m., the children $\blue{had \:assembled}$ in the ground.
• At 9:30 p.m., the Rajdhani Express $\blue{had \:departed}$.
