Oraciones Simples Orden de las palabras Una oración nos dice “algo”, contiene una idea. Es una Oración Simple aquella que sólo nos cuenta una sola cosa. El orden de las palabras en una oración es muy importante. Observa estas dos oraciones. Ambas contienen las mismas palabras pero no dicen los mismo: The policeman arrested the thief The thief arrested the policeman Una Oración Simple puede tener seis partes, pero no siempre tiene esa misma cantidad. Estudia la siguiente tabla y nota cómo la columna nro. 6 (When?) puede estar al principio o al final de la oración. 6
1 When?
Last week
2 Who? Which? What?
3 Action
I I
went had
The play
was
I A young man and a young woman They
did not enjoy were sitting
4 Who? Which? What?
5 How?
6 Where?
When?

were talking
behind me.
loudly
Algunos adverbios (por ejemplo always, also, probably) van con el verbo en medio de una oración. Tom always goes to work by car We were feeling very tired and we were also hungry Estudia estas reglas. (puede haber excepciones) 1- Si el verbo es una palabra (goes/fells/cooked, etc) , el adverbio usualmente va antes del verbo
Tom always goes to work by car Observa que estos adverbios (always/often/also, etc) van antes de Have to Jim never phones me. I always have to phone him 2- Los adverbios van después de am/is/are/was/were: We were feeling very tired and we were also hungry. 3- Si el verbo es de dos o más palabras (can remember/doesn’t smoke/has been stolen, etc) al adverbio va después del primer verbo (can/doen’t/has, etc) I can never remember his name Ann doesn’t usually smoke Observa que probably va después del negative: I probably won’t see you También usamos all y both en esta posición: We all felt ill after the meal
Laboratorio de Idioma II: – Docente Marcela Morejón
5 Escuela Técnica Vial Nacional Nº 2 “Ing. Juan Domingo Pío” My parents are both teachers We are all going out this evening A veces usamos is/will/did, etc en lugar de repetir parte de una oración. Observa la posición de always/never, etc en estas oraciones. He always says he won’t be late but he always is I’ve never done it and I never will
Tiempos Verbales Present Tenses
Presente perfecto Sujeto + have / has + pasado participio Usamos este tiempo verbal: Cuando hay conexión con el presente. Ej. I have washed my car (it is clean now) Para dar información nueva o anunciar un acontecimiento reciente. Ej. I have lost my purse. Can you help me? Para hablar sobre experiencias personales o acontecimientos de la vida. Ej. I have been to America twice El ‘present perfect simple’ conecta / une el pasado y el presente de una manera parecida al pretérito perfecto en español. Si decimos que algo ha ocurrido ('has happened'), pensamos del pasado y del presente a la vez como si hiciésemos un puente del pasado al presente. Ejemplo: - I can’t do my homework because I’ve lost my book. - No puedo hacer mis deberes porque he perdido mi libro. Así que muchas veces podemos cambiar una frase del ‘present perfect simple’ al ‘present simple’ y queda con un significado parecido.
I’ve lost my book I don’t have it now Have you seen the new Leonardo Di Caprio film Do you know it. Your sister has left the door open The door is open now Hasn’t Danny got married yet? Is he still single? I’ve finally found a job I have a job now El ‘present perfect’ es usado frecuentemente con las siguientes expresiones de tiempo: Ever and never Have you ever been to Scotland? / ¿Has estado alguna vez en Escocia? I’ve never eaten paella. / Nunca he comido paella. Just
I’ve just made tea, would you like a cup? / Acabo de hacer té. ¿Quieres una taza? Ana and Jesús have just had a baby / Ana y Jesús acaban de tener un niño.

6 Escuela Técnica Vial Nacional Nº 2 “Ing. Juan Domingo Pío” Recently and lately I’ve recently passed the F.C.E. exam and I’m studying for the C.A.E. / Acabo de aprobar el exámen de FCE y estoy estudiando para el CAE. Have you seen John lately? / ¿Has visto a John ultimamente? So far
I’ve had three beers so far this evening and it’s only eight o’clock! / He tomado hasta ahora tres cervezas esta tarde y sólo son las ocho. Yet and already 'yet' - normalmente se utiliza en frases interrogativas y va al final de la oración. Se usa cuando esperamos que algo va a pasar en el futuro, no en el pasado ni en el presente.
Have you done your homework yet? / ¿Has terminado ya los deberes? I don’t think Manoli has done the shopping yet. / Creo que Manoli todavía no ha hecho la compra. 'already' - se usa en frases afirmativas e interrogativas y normalmente va detrás de los verbos auxiliares o modales y delante de los demás verbos. Con 'already' decimos que algo está en el presente o el pasado, no en el futuro. Yes, I’ve already finished my homework / Sí, ya he terminado mis deberes En Inglés británico yet y already acompaña habitualmente a los tiempos perfectos. En Inglés Americano prefieren usar los tiempos pasados. Compara: Have you phoned your mother yet? (UK) Did you phone your mother yet? (USA) I’ve already phoned her (UK) I already phoned her (USA) Since and for 'For' - (how long something has lasted) Se usa para decir cuánto tiempo ha durado una acción. En español suele decirse ‘desde hace’. We’ve had this computer for about six months. / Tenemos esta computadora desde hace unos seis meses. 'Since' - (when something started) Se usa como una referencia a un punto de tiempo cuando algo empezó. En español suele decirse ‘desde’ o ‘desde que’.
We’ve had this car since January / Tenemos este coche desde enero. Comparar:
I’ve known Eric since 1989.
I’ve known Eric for 15 years (si estamos en 2004)
Presente perfecto continuo Sujeto + have / has + been + (verbo + ing) Usamos este tiempo verbal: Cuando hablamos sobre un periodo de tiempo que continua hasta el presente. Ej. I have been feeling very tired lately Para describir una actividad que ha tomado mucho tiempo. Ej. Where have you been? I have been playing rugby Para enfatizar la duración de tiempo que ha tomado una actividad. Ej. I have been waiting for an hour and she hasn’t phoned yet

Past Tenses
Pasado Continuo Sujeto + was / were + (verbo + ing) Usamos este tiempo verbal Para describir una acción que estaba incompleta cuando otra acción sucedió. Ej: While I was doing my homework the phone rang
Pasado perfecto Sujeto + had + pasado participio Usamos este tiempo verbal: Usamos este tiempo verbal para describir un evento que sucedió antes de que otro evento en el pasado. Ej. When I arrived at the airport, the plane had taken off
Para hablar sobre dos tiempos a la vez: el pasado y otro pasado anterior a este. I lived in Spain for 10 years, but I had also lived there for 5 years before that. (Viví en España 10 años pero anteriormente también había vivido aquí 5 años.)
Pasado perfecto continuo Sujeto + had + been + (verbo + ing) Usamos este tiempo verbal para expresar por cuánto tiempo algo ha estado sucediendo antes de que algo más sucediera. Ej. He had been waiting for twenty minutes when the bus finally arrived Utilizamos este tiempo para referirnos a eventos pasados que eran continuos y fueron llevado a cabo durante un periodo de tiempo en el pasado. Ejemplo He had been waiting for his parcel for one week. Él había estado esperando su paquete durante una semana
I had been studying all morning. (Había estado estudiando toda la mañana)
Laboratorio de Idioma II: – Docente Marcela Morejón
8 Escuela Técnica Vial Nacional Nº 2 “Ing. Juan Domingo Pío” También podemos utilizar el pasado perfecto continuo para mencionar una acción continua en el pasado que tiene consecuencias en el presente o en el pasado especificando cuando comenzó la acción. Podemos expresar el momento en el que la acción continua empezó utilizando un adverbio de tiempo o una frase que indique un punto en el tiempo. Ejemplo Since he watched that film, he had not been sleeping properly. Desde que vio esa película, él no había estado durmiendo bien
Future tenses
Futuro simple Sujeto + will + verbo infinitive Este tiempo verbal es usado: Para expresar un evento general o indefinido en el futuro. Ej. I will probably go on holliday next month Para ofrecer colaboración en algo. Ej. That bag is too heavy for you. I will help you with it Para pedirle algo a alguien. Ej. Will you take it to the library for me, please?
Futuro progresivo Esta forma del futuro es usada en inglés con mayor frecuencia que en español. Su estructura es la siguiente:
sujeto+ futuro de 'to be' + gerundio del verbo a conjugar
You will be flying to Paris tomorrow at this hour / Mañana a esta hora estarás volando hacia Paris Sirve para indicar una acción que se desarrollará en el futuro. Pueden ser acciones o situaciones que no conocemos cuándo exactamente se producirán aunque también puede expresar acciones ya planificadas y que se producirán en un determinado momento.
They will be leaving tomorrow / Ellos saldrán mañana Las formas negativa, interrogativa e interrogativa-negativa se construyen de forma análoga a la explicada para el futuro simple. FORMA NEGATIVA
FORMA INTERROGATIVA
FORMA INT. NEGATIVA
I shall / will not be playing no estaré jugando
shall / will I be playing? ¿estaré jugando?

PASIVA
Usos: Usamos un verbo en voz activa para describir acciones y eventos. Por ejemplo: Paper still plays a vital role in our lives –newspapers tell us the events of the day, and books entertain and educate us. Paper has been with us since 105 AD. The Chinese first used it to make records; later it spread to all parts of the world. Podemos usar la Voz Pasiva en las siguientes situaciones: 1) No es relevante el sujeto que realiza la acción. Ej. Ancient paper was made entirely of rags, modern paper is made from wood pulp –a faster and cheaper alternative. 2) En descripción de procesos. Ej. First the logs are stripped of barks, cut into smaller sections, and made into chips. The chips are put into a large tank called a digester and allowed to stew in a chemical mix under pressure.

Oraciones de Relativo
(Relative Clauses)
Ejemplos: - Logistics is the business function which controls the movement of physical materials in a factory - Our logistics department, which controls the movement of physical materials in the factory, is headed by Barry Perks. - A mine is a place where ores, coal, and precious stones may be obtained. - A miner is a person who works in a mine - You need to speak to John Martin, who is in charge of the coal mine. Forma: Las oraciones de relativo nos proporcionan información adicional sobre algo ya mencionado. Estas oraciones son una clase de oración subordinada: The man who lives next door is Italian. who se refiere a “the man” She´s got a cat which she found in the street. which se refiere a “a cat” Los pronombres relativos principales en inglés son who y which (que a veces se sustituyen por that) y equivalen en español a “que”. Who se utiliza para referirnos a personas y which a cosas o animales. Más ejemplos: I like those houses which have a garden. The dress which she bought was very expensive. These are the cakes which Paul likes. They are looking for someone who speaks Japanese. Is that the woman who lives upstairs? That´s the boy who goes to school with Jill.
Hay dos clases de Oración de Relativo: 1) Defining relative clauses Ejemplos: The man who works in the bar is a friend of mine. That house which has been painted is my aunt´s. En los ejemplos anteriores no se puede omitir la oración de relativo, ya que ésta proporciona información esencial para poder identificar a “the man” y “that house”. 1. That: en las defining relative clauses, who y which pueden sustituirse por that: The man that works in the bar is a friend of mine. That house that has been painted is my aunt´s. 2. Omisión de who, which o that: cuando estas palabras actúan como objeto de la oración, y no como sujeto, pueden omitirse. The book which/that you bought for me. The book you bought for me. The person who/that I met on holidays. The person I met on holidays. Sin embargo, no se pueden omitir en estos casos porque actúan como sujeto: The man who/that works in the bar is a friend of mine. That house which/that has been painted is my aunt´s.
Laboratorio de Idioma II: – Docente Marcela Morejón
21 Escuela Técnica Vial Nacional Nº 2 “Ing. Juan Domingo Pío” 2) Non-defining relative clauses Ejemplos: My friend Sarah, who lives in Germany, has won the lottery. We went to see a film yesterday, which was quite good. En estos ejemplos la oración de relativo nos presenta información adicional, pero no esencial. Podríamos omitir la oración de relativo y el sentido general del enunciado sería el mismo. 1. Comas: estas oraciones llevan siempre coma delante del pronombre relativo. 2. Who y which: no es posible sustituirlos por that, ni omitirlos. Si “who” o “which” van en medio, necesito dos comas, una para abrir y otra para cerrar. Ejemplo: My friend, who you don't know, is coming today. (Mi amigo, a quien no conoces, viene hoy.) ¿Para qué nos sirve saber distinguir entre “identifying” y “non-identifying relative clauses”? La distinción entre indentifying y non-identifying relative clauses nos sirve para saber cuándo utilizar “that”. Estudia esta regla: • “That” se utiliza generalmente para identificar personas y cosas en las “identifying relative clauses” (no se usa generalmente en las non-identifying) Ejemplo: The woman that you know. También podría decir: “The woman who you know.” La mujer que tú conoces. Nota: Con “that” estoy identificando a la mujer. Recuerda: “that” se utiliza generalmente para sustituir a “who” o “which” en oraciones que identifican a la persona o cosa. No se se sele utilizar en oraciones en las que ya se ha identificado a la persona cosa: Por ejemplo, no decirmos: “Mr. Smith, my friend, that you know. Las preposiciones van al final en las oraciones de relativo: That´s the boy (who) I was talking to. Tim is the friend (who)she went to the cinema with. Excepción: puede utilizarse una preposición + whom en lugar de situar who al final, pero resulta más formal: The girl (who) he talked to The girl to whom he talked. The friend (who) Tom went out with The friend with whom Tom went out. La siguiente tabla muestra el rango de pronombres relativos: Persona Cosa Lugar Who/that Which/that Sujeto Who/whom/that/ø Which/that/ ø Where Objeto Whose whose Posesivo
Tiempo
Razón
When
Why
¿Cuál es la diferencia entre “who” y “whom”? Whom es más formal que who, lo cual quiere decir que cuando queramos hablar de forma más elegante utilizaremos "whom" en vez de "who".
