ejercicios para recordar(some,any,a,an)

A y an significan un, una indistintamente, y se emplean con nombres contables en singular. A se pone cuando la palabra siguiente empieza por consonante; an, por vocal.

A cat (Un gato)

An ocean (Un océano)

An orange bike (Una bici naranja)



Obsérvense los siguientes ejemplos:

An hour (Una hora --> Nótese que la h es muda, por lo que hour empieza por un sonido vocálico.)

A hot dog (Un perrito caliente --> La h se pronuncia aquí.)

A university student (Un estudiante universitario --> La u de "university" no tiene un sonido vocálico, sino que más bien, consonántico. Equivaldría a decir yu en castellano.)

An unusual situation (Una situación poco corriente o inusual -->La u es una vocal aquí.)



El plural de a o an es some:

Some cats (Unos gatos)

Some oceans (Unos océanos)



Some se usa también para sustantivos incontables: some milk (leche, un poco de leche).



En negativa y en interrogativa se emplea any en vez de some:

Sin embargo, en los casos siguientes empleamos some en las interrogativas: en peticiones, en ofrecimientos o cuando esperamos una respuesta afirmativa.

Is there some ham in the fridge, mum? I'm very hungry. (¿Hay jamón de York en la nevera, mamá? Tengo mucha hambre. -->El hablante le está pidiendo a su madre de una forma indirecta jamón, y espera que ella le diga que sí.)



El artículo definido the (el, la, los, las) se utiliza para referirnos a cosas ya introducidas en el discurso o para referirnos a algo único:

Some, any y the no se mencionan cuando los sustantivos expresan una idea general:
