1. Questions Forms

YES/NO QUESTIONS

In questions that can be answered with either yes or no, we put an auxiliary verb before the subject.

Examples:

OPEN QUESTIONS

1. We use questions words such as what, where, why, and how to ask for more information. The question word comes before the auxiliary verb (pay attention to the following examples).

2. We use what if there are many possible answers and which if there are fewer possible answers.

Examples:

• What is their policy?
• Which of these computers is yours?

3. If who or what is the subject of the sentence, the word order is the same as in a statement.

Examples:

• Who organizes the travel arrangements? (subject + verb + complement)
• What happened when things go wrong? (subject + verb + complement)

4. If who, what or which asks about the object, we put the auxiliary after the object.

Examples:

• Who of you are in charge of the Marketing Department?
• What number did you ring?
• Which restaurant have you chosen?

5. The question word can be followed by an adjective or adverb.

Examples:

• How big is the company?
• How good is your English?
• How well do you speak English?
• How far is the hotel from here?
• How often do you travel?

1.2 INDIRECT QUESTIONS

When we want to be polite, we ask indirect questions. 

We start with an expression such as: Can/Could you tell me...," Do you know..., I'd like to know... In these questions, the word order is the same as in an affirmative sentence.

Examples

• Can you tell me how many rooms your flat has? (Direct question: How many rooms does your flat have?) 
• Do you know how old she is? (Direct question: How old is she?)

For yes/no questions, we form indirect questions using if or whether. 

Example

• I'd ke to know if the bus leaves from here. (Direct question: Does the bus leave from here?)

THE SIMPLE PAST 

FORM

USE 1. Completed Action in the Past 

Use the Simple Past to express the idea that an action started and finished at a specific time in the past. Examples:

• I saw a movie yesterday.
• Last year, I traveled to Japan.
• Did you have dinner last night?
• He didn't wash his car.

USE 2. A Series of Completed Actions 

We use the Simple Past to list a series of completed actions in the past. These actions happen 1st, 2nd, 3rd, 4th, and so on.

Examples:

• I finished work, walked to the beach, and found a nice place to swim.
• He arrived from the airport at 8:00, checked into the hotel at 9:00, and met the others at 10:00.
• Did you add flour, pour in the milk, and then add the eggs?

USE 3. Duration in Past 

The Simple Past can be used with a duration which starts and stops in the past. A duration is a longer action often indicated by expressions such as: for two years, for five minutes, all day, all year, etc. 

 Examples:

• I lived in Brazil for two years.
• They sat at the beach all day.
• They did not stay at the party the entire time.
• We talked on the phone for thirty minutes.
• How long did you work there?

4. Past Continuous

THE PAST CONTINUOUS
FORM

The past continuous is formed with was/were + the -ing form of the verb:

Examples:

• She was always coming late for dinner!
  
• You were always coming late for dinner!
  

We usually use the Past Continuous to talk about activities that lasted for some time in the past. The actions can be interrupted by something or can be happening at the same time.

USE 

1.Duration in the past
2.Interrupted actions in progress
3.Actions in progress at the same time in the past

USE 1: Duration in the past 

We use the Past Continuous to talk about actions or situations that lasted for some time in the past, and whose duration time is unknown or unimportant.

Examples:

• I was watching TV yesterday in the evening.
  
• She was sleeping on the couch.
  
• The dog was barking. 

USE 2: Interrupted actions in progress

The Past Continuous is often used when one action in progress is interrupted by another action in the past. We usually use when or while to link these two sentences.

Examples:

• I was talking with James when the telephone rang.
  
• While Angelica was playing tennis, the plane crashed. 
  
• When Bob was painting windows, it started raining. 
  

USE 3: Actions in progress at the same time 

We also use this tense to talk about two or more activities happening at the same time. We usually use when or while to link the two sentences. 

Examples:

• I was watching TV and Barbara was reading a book.
  
• While Barbara was reading a book was eating the dinner and talking. 
• When Bob was painting windows, Mary was working in the kitchen.
