Some Animal Heroes

On 14 July the classes V to VII of CBSEi visited National Agricultural Science Museum (NASM), situated in the National Agricultural Science Centre campus of ICAR in New Delhi,  the first of its kind in the country.

Modals are different from normal verbs:

1: They don't use an 's' for the third person singular.
2: They make questions by inversion ('she can go' becomes 'can she go?').
3: They are followed directly by the infinitive of another verb (without 'to').

Probability:

First, they can be used when we want to say how sure we are that something happened / is happening / will happen. We often call these 'modals of deduction' or 'speculation' or 'certainty' or 'probability'.

For example:

• It's snowing, so it must be very cold outside.
• I don't know where John is. He could have missed the train.
• This bill can't be right. £200 for two cups of coffee!

For example:

• She can speak six languages.
• My grandfather could play golf very well.
• I can't drive.

Obligation and Advice

We can use verbs such as 'must' or 'should' to say when something is necessary or unnecessary, or to give advice.

For example:

• Children must do their homework.
• We have to wear a uniform at work.
• You should stop smoking.

Permission

We can use verbs such as 'can', 'could' and 'may' to ask for and give permission. We also use modal verbs to say something is not allowed.

For example:

• Could I leave early today, please?
• You may not use the car tonight.
• Can we swim in the lake?

Habits

We can use 'will' and 'would' to talk about habits or things we usually do, or did in the past. 

For example:

• When I lived in Italy, we would often eat in the restaurant next to my flat.
• John will always be late!

Degrees of Adjective

DEGREES OF ADJECTIVE

Definition :

Every adjective has three degrees of its own. They are : Positive, Comparative, Superlative degrees.

There are two types of Adjectives :

Regular Adjectives

Definition :

Regular adjectives make their comparative and superlative forms by adding ‘er’ and ‘est’.

e.g.

Positive	Comparative	Superlative
bold	bolder	boldest
bright	brighter	brightest
black	blacker	blackest
great	greater	greatest
old	older	oldest
proud	prouder	proudest
warm	warmer	warmest
mean	meaner	meanest

Some adjectives are added with only ‘r’ to form comparative and ’st‘ to form superlative degree.

e.g.

Some adjectives are added with ‘consonant + er’ to form comparative and ‘consonant + est’ to form superlatie degree

e.g.

Positive	Comparative	Superlative
fat	fatter	fattest
red/td>	redder	reddest
sad	sadder	saddest

Some adjectives add ‘er’ and ‘est’ to form comparative and superlative by replacing the last letter ‘y’ into ‘i’

Positive	Comparative	Superlative
dry	drier	driest
busy	busier	busiest
early	earlier	earliest
ugly	uglier	ugliest

e.g.

If an adjective has two or more than tow syllables we use more or most to form comparative and superlative degree

e.g.

Positive	Comparative	Superlative
active	more active	most active
beautiful	more beautiful	most beautiful
careful	more careful	most careful
proper	more proper	most proper
faithful	more faithful	most faithful

Irregular Adjectives

When there is a complete change in comparative and superlative degrees, they are called irregular adjectives.

e.g.

Positive	Comparative	Superlative
good	better	best
bad	worse	worst
little	less	least
old	older	oldest
far	farther	farthest
