COMPARATIVES//SUPERLATIVES

MAIN USE

Comparatives are used to compare two things and to highlight the superiority, inferiority, or equality of one term compared to another.
For comparisons in larger groups, you must use the superlative. The superlative designates extremes: the best, the first, the worst, the last, etc.

SUPERIORITY :

a) Short adjectives: adj+ er than

• Peter is taller than Sandra.

b) COMPARATIVES : Long adjectives: :MORE + adj + THAN

• A Ferrari is more expensive than a Mini.

SUPERLATIVE:

Short & long adjectives:
THE ADJ+-EST/IESTt…  THE MOST/THE LEAST + adjective…

• It's the nicest place i've ever visited
• This is the most pleasant place on Earth!

EQUALITY

Short & long adjectives:
AS… adjective… AS..

• English is as easy as German. Doesn't exist
• INFERIORITY Short & long adjectives::LESS + adjectif + THAN
• July is less cold than January.

NOTES:

Short adjectives: 1 syllable (eg: young) + 2-syllable adjectives ending in -y (eg: pretty)
Long adjectives: all the other adjectives

COMPARATIVES:
> If the adjective ends in "–y" the "y" becomes "i" : heavy –> heavier
> If the adjective ends in "–e" only an "r" is needed: wise –> wiser
> If the adjective ends with "single vowel + consonant" the consonant is doubled and one adds "–er" : big –> bigger
> Some very common adjectives have irregular comparatives: good –> better | bad –> worse | far –> farther

SUPERLATIVES:
Irregular forms:         good –> the best ·         bad –> the worst ·         far –> the farthest

PHRASAL VERBS:

Phrasal Verbs are verbs with more than one word.

Examples: pick up, put down, turn on, turn off…

Phrasal verbs are also called 'two-part verbs' and 'three-part verbs.'

There are two types of phrasal verbs: separable and non separable.

Non separable phrasal verbs are sometimes called 'inseparable.'

Non separable (n) phrasal verbs must always remain together:

Example: take off = (n) to depart
CORRECT:     The plane took off at noon.         (verb + particle together)
XX INCORRECT: The plane took at noon off.   (both words MUST be together)

Separable (s) phrasal verbs can be written three different ways:
Example: take off (s) = to remove clothing
CORRECT:   Sara took off her jacket.   (verb + particle together)
CORRECT:   Sara took her jacket off. (verb + particle separated by noun)
CORRECT:   Sara took it off.         (verb + particle separated with a pronoun)
XX INCORRECT: Sara took off it.       (the pronoun MUST be in the middle)

THE PASSIVE VOICE:

The passive voice requires a "double verb" and will always consist of a form of the verb "to be" and the past participle (usually the "en/ed/t" form) of another verb. Example: is kicked

You should be familiar with the forms of "to be" so that they can easily identify the passive voice in their work.

Review the forms of "to be": am, is, are, was, were, be, being, been

Note the forms of "to be" in the examples of the verb "to kick" in various forms of the passive voice:

is kicked—————-had been kicked
was kicked————-is going to be kicked
is being kicked———will be kicked
has been kicked——-can be kicked
was being kicked——should be kicked

Often passive voice sentences will contain a "by" phrase indicting who or what performed the action. Passive sentences can be easily transformed into active sentences when the object of the preposition "by" is moved to the subject position in the sentence.

Passive: The cookies were eaten by the children.
Active: The children ate the cookies.

Passive: English is spoken all over the world.
Active: People speak English all over the world.

in spite of + noun

although + clause

despite + noun

though + clause

even though + clause

**Although and though can be used in the same way.
**Despite and in spite of are normally used as prepositions, they can also be used in adverbial constructions with -ing, thus:
1. 'I managed to pass my exams, despite going out four times a week during the revision period.'
2.'In spite of feeling terribly sick, I went to work every day that week.'
