Los auxiliares Don´t y Doesn´t

Con DON´T (pronúnciese don´t) y DOESN´T (pronúnciese dósent) se forma el presente negativo de todos los verbos en inglés, salvo el de los verbos auxiliares.

DON´T es la contracción de do not y DOESN´T de la de does not.

En la forma negativa los mencionados auxiliares siempre se anteponen al verbo que se emplee, o sea, le siguen inmediatamente al sujeto o pronombre personal.

Formula general del negativo

SUJETO + AUXILIAR + NOT + VERBO en su forma original
I	DO	NOT	speak	Yo no hablo
You	DO	NOT	see	usted no ve
He	DOES	NOT	eat	Él no come
She	DOES	NOT	drink	Ella no bebe
They	DO	NOT	buy	Ellos no compran

Veamos ahora estas mismas oraciones pero haciendo uso de las contracciones, las cuales son de suma utilidad en el inglés hablado.

I	DON´T	Speak
You	DON´T	See
He	DOESN´T	Eat
She	DOESN´T	Drink
They	DON´T	buy

DON´T y DOESN´T también varían de acuerdo con el sujeto o pronombre personal. Úsase DON´T, al igual que DO, para I, you, we, you, y they.DOESN´T, lo mismo que DOES, únicamente para he, she, it.

Ejemplos:

I	DON´T	buy	Yo no compro
You	DON´T	speak	Usted no habla
He	DON´T	drink	Nosotros no bebemos
She	DON´T	eat	Ustedes no comen
They	DON´T	see	Ellos no ven
He	DOESN´T	buy	Él no compra
She	DOESN´T	speak	Ella no habla
It	DOESN´T	eat	No come impersonal: al referirse a un animal

Veamos ahora la condensación de los anteriores en forma esquemática:

I	DON´T speak	He	DOESN´T speak
You
We		She
You
they		It

Haga siempre uso del auxiliar negativo DOESN´T y el pronombre neutro IT en el presente negativo de cualquier vero impersonal.

Ejemplos:

It DOESN´T rain no llueve

It DOESN´T snow no Nieva

Emplee asimismo DOESN´T en oraciones negativas en tiempo presente inmediatamente después de las terceras personas del singular, como:Frank, Mary, the boy, the girl etc., y DON´T inmediatamente después de las demás personas, como: the boys, the girls, the children, ect.

Lea estas oraciones en voz alta y note el cambio del afirmativo al interrogativo, así como también el empleo de DO.

They	study	in school	every day
Frank and Mary	learn	English	in school
They	learn	English	in school
The children	eat	at home	every day
They	eat	at home	every day
DO the boys	study	in school	every day?

DO Frank and Mary	learn	English	in school?
DO they	learn	English	in school?
DO the children	eat	at home	every day?
DO they	eat	at home	every day?

Obsérvese la modificación que sufre la forma verbal (studies, study) al pasar del afirmativo al interrogativo, cuando se emplea la tercera persona del singular: he, the boy, the studant, Frank…

Así mismo nótese DOES en las preguntas.

The boy		studies	in school		every day
He		studies	in school		every day
The student		learns	english		in school
He		learns	english		in school
Frank		eats	at home		every day
He		eats	at home		every day
DOES	The boy		study	in school		every day?
DOES	He		study	in school		every day?
DOES	The student		learn	english		in school?
DOES	He		learn	english		in school?
DOES	Frank		eat	at home		every day?
DOES	He		eat	at home		every day?

Observe en esta gráfica como en el presente negativo DOESNT sigue inmediatamente a un sujeto en singular (the boy) y DON´T a un sujeto en plural (the boys).

Además nótese los verbos en su forma simple (study, learn…).

The boy	DOESN´T	study	every day
The boys	DON´T	study	every day
The student	DOESN´T	Learn	English
The students	DON´T	Learn	English
Frank	DOESN´T	eat	at home
Frank and Mary	DON´T	eat	at home
