Congratulations on successfully passing the sixth module! 🙂

In this Grammar Review (2) seventh course module, we will be taking a look at (7.1) Modal verbs, (7.2) Prepositions and particles of speech, (7.3) Articles – Definite/Indefinite. It is essential that you thoroughly read through all the information presented within this module, before then completing the Module Quiz and proceeding to the eighth module. If you have any module-related questions, please contact your personal tutor through the CONTACT LESSON TEACHER button. Good luck and we hope you enjoy completing your seventh module! 🙂


(7.1) Modal verbs.

Modal verbs are auxiliary verbs that express certainty, necessity, obligation, possibility and probability. Modals verbs are also utilized as language functions when talking about ability, asking permission, making requests and offers, etc.

The modal verbs and semi-modal verbs used in the English language are:

Can | Could | Be able to | May | Might | Shall | Should | Ought to | Will | Would | Must | Have to | Need to | Don’t have to | Needn’t |

We are now going to look at each modal verb grouping; identifying their usages and grammatical functions.

Can, Could, Be able to.

Can, Could, Be able to, are used to express ability/lack of ability, possibility/impossibility, asking/giving permission, making suggestions.

Ability/lack of ability examples:

Please note that the past tense of these modal verbs are formed by Could / Couldn’t / Was / Wasn’t / Were / Weren’t / Hasn’t / Haven’t /.

Possibility/impossibility examples:

Asking/giving permission examples:

Making a suggestion example:

May, Might.

May and Might, are used to express formal permission/formal prohibition, polite requests, possibility/impossibility, making suggestions.

Formal permission/formal prohibition examples:

Polite requests example:

Possibility/impossibility examples:

Making suggestions examples:

Shall, Should, Ought to.

Shall, Should and Ought to, are used to express offering of assistance/polite suggestions, predictions/expectations, giving advice.

Offering of assistance/polite suggestions examples:

Predictions/expectations example:

Giving advice examples:

Will, Would.

Will and Would, are used to express polite requests/statements, habitual past actions.

Polite requests/statements examples:

Habitual past actions examples:

Must, Have to, Need to, Don’t have to, Needn’t.

Must, Have to, Need to, Don’t have to and Needn’t, are used to express necessity/requirement, certainty, persuasiveness, prohibition/forbidden, lack of necessity.

Necessity/requirement examples:

Certainty example:

Persuasiveness examples:

Lack of necessity examples:


(7.2) Prepositions and particles of speech.

A preposition is a word which usually governs and precedes a noun or pronoun, and expresses a relationship to another word or element in the clause, for example: ‘the woman is in the car’, ‘she arrived after dark’, ‘what did you want it for?’.

The English language has many prepositions, and the following table – containing the most commonly-used prepositions – will provide you with an overall idea as to what it means for a word to be classed as a preposition:

In this section of the module, we are going to look at one particular set of prepositions: Prepositions of Time. And we are going to look at just three prepositions, to illustrate how you can effectively teach prepositions in your classes:

In | At | On |

Let’s begin by introducing some nouns, which we will be using for this example activity:

Saturday | April | 2020 | Birthday | Yesterday | Tomorrow | Noon | Midnight | Summer | Weekend | Morning | Christmas | 4 o’clock | Dawn | Sunset | Next week | Fortnight | Black Friday | Night |

Now, let’s present this information as a whiteboard class activity:

The second part of this activity will be for the students to step up to the board and decide which noun goes with which preposition. This is the (trial and error) Practice stage of the lesson. The correct answers should look like so:

(please note here that in British English, the preposition ‘At’ is used in connection with the noun, ‘Weekend’).

As you can see, three of the Prepositions of Time haven’t been included on the table because they are not preceded by a Preposition of Time (‘Tomorrow’, ‘Next Week’ and ‘Yesterday’).

It would be very unusual for the class to guess all the correct answers, so this complete table is a result of corrections to the table contents.

The next step will be to ask learners what they think the grammar rules are for using ‘In’, ‘At’, ‘On’ as Prepositions of Time.

The answer is that ‘In’ is used for longer periods of time, ‘At’ is used for specific times and ‘On’ is used for days.

A Production activity could involve the learners thinking of other time-related nouns and also adding them to the table.

Particles of speech.

A word that looks like a preposition but is actually part of a verb is referred to as a Particle of Speech.

An example sentence: ‘three aggressive men held up the store’.

‘Held up’ is a verb, meaning ‘to rob’. Therefore, ‘up’ is not a preposition, and ‘store’ is not the object of a preposition. Instead, ‘store’ is the direct object of the verb ‘held up’.

You can avoid confusing prepositions with particles with a simple test. Try moving the word ‘up’ and the words following it to the front of the sentence: ‘up the store three aggressive men held’.

If the resulting sentence doesn’t make any sense, then the word belongs with the verb and is a particle, not a preposition.


(7.3) Articles – Definite/Indefinite.

In the English language, there are three articles: ‘a’, ‘an’ and ‘the’.

Both ‘a’ and ‘an’, are referred to as being indefinite articles, and ‘the’ is the definite article.

Articles are used before nouns or noun equivalents and are a type of adjective. ‘The’ is used before a noun to indicate that the identity of the noun is known to the reader. ‘A’ and ‘An’ are used before a noun that is general or when its identity is not known.

The method of knowing when to use each article appropriately, is to follow these three simple rules:

  1. ‘The’ is placed before a singular or plural noun.
  2. ‘A’ is placed before a singular noun beginning with a consonant sound.
  3. ‘An’ is placed before a singular noun beginning with a vowel sound.

So, for example:

  1. ‘The pen is on the table’.
  2. ‘A hat protects you from the sun’.
  3. ‘An umbrella protects you against the rain’.

Students often understand these grammar rules with ease, but experience difficulties when it comes to situations when indefinite articles are replaced by definite articles when describing the same object. Such as:

‘I drank a glass of water this morning. The glass of water was lovely’.

In this example sentence, we begin using the indefinite article ‘A’ because it is placed before a singular noun beginning with a consonant sound. However, once the noun has become established (in other words when it has already been mentioned) we then refer to it by using the definite article.

Please also note that we don’t use any articles before proper nouns (such as countries, for example). We also don’t use indefinite articles when describing uncountable nouns, but we can add an article by inserting a quantifier. So while it isn’t possible to say that you would like an oil, it is possible to say that you would like a can of oil. The quantifier in this sentence is, ‘can’.

The following are some examples of article usages:

There are many specific rules when not to, or when to add articles – such as when referring to geographical features – and the list is far too extensive to list here in this module. We have covered the essentials and if you are asked a difficult question regarding articles in your class, we advise looking up the specific article rule for that specific noun or pronoun term.
