COMPARATIVE AND SUPERLATIVE ADVERBS

COMPARATIVE AND SUPERLATIVE ADVERBS

With adverbs ending in -ly, you must use more to form the comparative, and most to form the superlative.

Adverb	Comparative	Superlative
quietly	more quietly	most quietly
slowly	more slowly	most slowly
seriously	more seriously	most seriously

EXAMPLES

·         The teacher spoke more slowly to help us to understand.

·         Could you sing more quietly please?

With short adverbs that do not end in -ly comparative and superlative forms are identical to adjectives: add -er to form the comparative and -est to form the superlative. If the adverb ends in e, remove it before adding the ending.

Adverb	Comparative	Superlative
hard	harder	hardest
fast	faster	fastest
late	later	latest

EXAMPLES

·         Jim works harder than his brother.

·         Everyone in the race ran fast, but John ran the fastest of all.

·         Some adverbs have irregular comparative and superlative forms.

Adverb	Comparative	Superlative
badly	worse	worst
far	farther/further	farthest/furthest
little	less	least
well	better	best

EXAMPLES

·         The little boy ran farther than his friends.

·         You're driving worse today than yesterday !

·         He played the best of any player.

HAVE TO AND NEED TO

HAVE TO

'Have to' is used to express obligation in English. Its use is very frequent. Below are the rules and some tips to use it corerctamente. Then there is an exercise with the answers to practice it.

SE FORMA: con have to + el verbo infinitivo: ver las diferentes formas abajo

AFIRMATIVO	NEGATIVO	INTEROGATIVO
I have to you have to he/she/it has to we have to they have to	I don´t have to you don´t have to he/she/it doesn´t have to we don´t have to they don´t have to	do you have to does he/she/it have to do we have to do they have to

Example:
I have to work everyday. (tengo que trabajar todos los dias)
I don´t have to work everday. ( no tengo que trabajar todos los dias)
Do you have to work everyday? (¿tienes que trabajar todos los dias?)

NEED TO

Need can be modal verb and full verb. As full verb corresponds to need. As a modal verb, it expresses a need that is not demanded by a law, logic or natural force. There is no external force that imposes the action, it is rather an inner force, as the examples will show. Spanish does not know these distinctions and therefore must be translated need as modal verb with having to.

1ª persona	I need (to)	Yo necesito	we need (to)	nosotros necesitamos
2ª persona	you need (to)	Tu necesitas	you need (to)	vosotros necesitáis
3ª persona	he / she / it needs (to)	él / ella necesita	they need (to)	ellos necesitan

Example:	1) I need need your daughter back. Tú necesitas a tu hija de vuelta. 2) We need experts; we need specialists; we need know-how. Necesitamos expertos, necesitamos especialistas, necesitamos conocimientos especializados. 3) We need real convictions, we need arrests, we needprosecutions. Necesitamos condenas reales, necesitamos arrestos, necesitamos procesos. 4) Only the majority of acts each term need satisfy this requirement, and no act need contain solely Christian material. Este requisito sólo debe cumplirse en la mayoría de los actos litúrgicos celebrados durante el curso y no es necesario que cada uno de ellos contenga exclusivamente elementos cristianos. 5) We need confidence to achieve this and the people of Europe need perspectives. Necesitamos confianza para lograr este objetivo y la población de Europa necesita perspectivas.
