Lesson 1 : Introducing Modals

Read the story of Helen Keller below. Notice the underlined words. When you finish reading, discuss the questions that follow.

The story of Helen Keller, the girl who could not see, hear or speak

I'd like you to know the story of Helen Keller, who could neither see nor hear from the time she was a baby. Yet the brilliant girl was able to overcome all those difficulties, to graduate from a college with honours and become a useful citizen.

I must say there was nothing wrong with Helen Keller when she was born. Her father and mother were very proud of their pretty baby, who tried to say "pa-pa" and "ma-ma".

For nineteen months Helen grew bigger and stronger. She was able to walk when she was a year old; she could say a few words. But one day the child fell ill. She must have been very ill. For days she had been suffering from high fever and soon the parents learned that their darling would never be able to see and hear. When Helen was 6 years old, her parents took her to famous doctors to find out if they could do something to make her hear and see again, but the doctors could do nothing. The child was hopelessly deaf. Dr. Bell said that Kellers should write to the Perkins Institution for the blind in Boston and ask if they would send someone to help the child.

1. What meanings do the underlined words convey?

2. Can you understand what mood/emotion is expressed by each of these words?

3. Can you change the forms of these words?

Read the Dialogue below and notice the underlined words. A list of various functions is given In the box. In pairs discuss what function Is expressed by each of the underlined words.

possibility          ability               permission               advice                strong obligation

 

Dialogue : A Visit to London

A : What do you think I ought to see in London first?
B : Well, historical places, I think. You should go to the Westminster Abbey, and if you can, go to the Houses of Parliament and the National Gallery.

A : And what about the British Museum? I was told one ought to see It.

B : I suppose you must go there. There you can find masterpieces of the world's best artists.

A : How can I get to the centre?

B: I think you can go by steamer down the Thames from Westminster to Tower Bridge. That's a very pleasant way to travel, and you can see the London Bridge and quite a number of buildings on the way.

[adaptad]

You might have noticed that the underlined words such as can, could, may, might, must, ought to, shall, should, will, and would, do not change form for different subjects. These are special verbs which behave irregularly in English. They are different from normal verbs like 'work, play, visit' They give additional Information about the function of the main verb that follows it. They have a great variety of communicative functions. They are known as Modals (also called modal verbs, modal auxilary verbs, modal auxillaries)

In the story and the dialogue above, the underlined words that you have come across are examples of modals. While discussing questions 1-4 above, what characteristics of modals have you talked about?

Read about the characteristics of modals and compare them with what you have discussed.

Some characteristics of modal verbs:

  • They never change their form. You can't add 's', 'ed', 'ing'.
  • They are always followed by an Infinitive without 'to' (except in phrases like ought to).
  • They are used to express certainty, possibility, willingness, obligation, necessity, ability.

Read the dialogues below. How many modals can you find? Do they have the characteristics discussed above?

Dialogues : Asking the Way

A : Excuse me. Can you tell me where Panthapath is, please?

B: Take the second turn on the left and then ask again.

A: Is It far?

B: No, you can walk it in ten minutes.

A: Thank you very much.

B: It's a pleasure.

A: Excuse me, please. Could you tell me how to get to the Novo Theatre?

B: Sure, go straight, take the first right turn and then the second left. You can't miss it.

A: Thank you.

B: That's OK.

So, what different modals are there in English? By now you should be able to make a list of the modal verbs. Here is one :

can,            could,            may,            might,            will,            would,            shall, ,            should, ,            must

Also you must have noticed some verbs of expressions such as dare, ought to, had better, and need not in the above story or dialogues. They often behave like modal auxillaries and may be added to the list of modals.

Remember, modal verbs are used to express functions such as:

  1. permission
  2. ability
  3. obligation
  4. prohibition
  5. lack of necessity
  6. advice
  7. possibility
  8. probability

 

Exercise :

Underline modals in the dialogues below. Tell your partner what function or emotion is expressed by each modal.

 

Dialogue 1: At Lunch

A : Would you like one more parata? 

B : No, thanks. I'm on a diet.

A: Please, do. You've hardly eaten anything. 

B: It's delicious, but I don't think I ought to.

 

Dialogue 2 : In a Restaurant

Waiter: Can I take your order, sir? 

Mr. X: Rice and vegetables for me, please.

Waiter: May I take your order, sir? 

Mr. N: Yes, I'd like to try the kebab, please.

 

Dialogue 3 

A : I mustn't forget to phone Jafar.

Lesson 2 : Uses of Modals

Uses of can and could

Work in pairs. Tell your partner what you can do now using the computers and the Internet. Also talk about what you were not able to do when computers and the Internet were not a part of your life.

Notice how you have used can/can't and could/couldn't in your talk. What differences do you notice between can and could?

                                  Dialogue 2

                                         A: Hello, friend, Can you help me?

Have you noticed the various ideas/modes expressed by can/could? Discuss the following questions :

  1. How do the speakers in Dialogue 1 talk about their past and present abilities/inabilities?
  2. How do the people in Dialogue 2 talk to give or ask for permission?

 

Now, read the following section to know more about the uses of can/could. 

The modal auxiliary can is used

  • to express ability (in the sense of being able to do something or knowing how to do something): He can speak Spanish but he can't write it very well.
  • to express permission (in the sense of being allowed or permitted to do something): Can I talk to my friends in the library waiting room?
  • to express possibility: (in the sense that something may happen) Bangladeshi cricketers can do better if they play more international matches.

The modal auxiliary could is used

  • to express an ability in the past : I could run five miles when I was young.
  • to ask for permission : Could I borrow your laptop for an hour?
  • to express present possibility : We could spend the afternoon just sitting around and talking.
  • to express possibility or ability within a given condition : If he studied harder, he could pass the exam.

 

Exercise 1

Complete the sentences below with can/could. Also discuss the meaning expressed by can/could in each sentences. You need to use the negatives (can't/couldn't) where necessary.

  1. She doesn't want to go to the swimming pool because she …………………… swim.
  2. We are going to the cinema tonight. You ……………………. come with us if you want to.

  1. We ……………. hurry home. I think it would be better and safer.
  2. We ….......... stand under a tree. It's not safe.
  3. Look, there's a man selling umbrellas. We …….......... buy one.

Discuss in pairs when and where you may use must/should/have to. Then read the section below to check your understanding.

Must is the most commonly used modal to express certainty. It can also be used to express necessity or strong recommendation, although people often use the form 'have to'.

One may use must not to prohibit actions, but this sounds very strong or rude. It is better to use softer modal verbs such as should not or ought not to discourage something rather than prohibit.

Examples :

  • This must be the right address! (certainty)
  • Students must pass an admission to study at this school. (necessity)
  • You must take some medicine for that cough. (strong recommendation)
  • Jenny, you must not play in the street! (prohibition)

 

Must not vs. Do not have to

Must not suggests that you are prohibited from doing something. Do not have to suggest that someone is not required to do something.

Examples :

  • You must not eat that. (It is forbidden, it is not allowed.)
  • You don't have to eat that. (You can if you want to, but it is not necessary)

Should is most commonly used to make recommendations or give advice. It can also be used to express obligation as well as expectation.

Examples :

  • When you go to Agra, you should see the Taj. (recommendation)
  • You should focus more on study and less on games. (advice)
  • I really should be in the class by 9.00 am. (obligation)
  • By now, they should already be in Dhaka. (expectation)

Have to is used to express certainty, necessity, and obligation.

Examples :

  • This answer has to be correct. (certainty)
  • The milk has to be stirred continuously to prevent burning. (necessity)
  • They have to leave early. (obligation)

Ought to is used to advise or make recommendations. Ought to also expresses assumption or expectation as well as strong probability, often with the idea that something is desirable. Ought not (without 'to') is used to advise against doing something.

Examples :

  • You ought to stop smoking. (recommendation) 
  • Robi ought to get the promotion. (It is expected because he deserves it.)
  • This piece of land ought to increase in value. (probability)
  • You ought not waste your time. (advice against doing something)

Complete the sentences using the italicized words below. Positive and negative forms can be used. Some gaps may have more than one answer.

  1. Ruma said you didn't need to buy her anything for her birthday, but I really think you ……………………......... at least get her some flowers.

Uses of shall, will and would

Make five promises expressing your strong willingness or determination to do something.

Example : I shall never be late at school.

Promises to keep

  1. ……………………………………………………………………………………………
  2. ……………………………………………………………………………………………
  3. ……………………………………………………………………………………………
  4. ……………………………………………………………………………………………
  5. ……………………………………………………………………………………………

Now, read the following sections to know about the use of will/would.

In certain contexts, will and would are interchangeable, but there are differences. Notice that the contracted form '// is very frequently used for will.

Will can be used to express willingness:

  • I'll wash the dishes if you dry them up.
  • We're going to the movies. Will you join us?

It can also express intention (especially in the first person):

          I'll do my exercises later on.

It can also express prediction:

  • specific: The meeting will be over soon.
  • timeless: Too much rain will destroy crops.

Would can also be used to express willingness:

  • Would you please take off your coat?
