Exercises:

Statements into questions

Change statements into questions 

sentence that tells us something is a statement. In modern English, auxiliaries are the only verbs which can be put before the subject of a sentence to form questions.
  • He is a good fellow.
  • Is he a good fellow?
  • They have won the race.
  • Have they won the race?
  • The cat will kill the mice.
  • Will the cat kill the mice?
In the case of other verbs, the auxiliaries do and its forms (does and did) have to be used before the subject.
  • John enjoys playing tennis. (statement)
  • Does John enjoy playing tennis? (question)
  • Sharon makes models from clay.
  • Does Sharon make models from clay?
  • Alice goes to school by train.
  • Does Alice go to school by train?
  • The children practise the violin each morning.
  • Do the children practise the violin each morning?
  • Our team played well yesterday.
  • Did our team play well yesterday?
  • He fell from the ladder.
  • Did he fall from the ladder?
  • They went to Mumbai.
  • Did they go to Mumbai?
  • She likes to see pictures.
  • Does she like to see pictures?
  • They make good cheese.
  • Do they make good cheese?

Rewrite in Negative.                                   


The following examples show some ways to make a sentence negative in the present tense.

  • Sentence: My guests are arriving now.   Negative: My guests are not arriving now.
The negative word no:
  • Sentence: Jennie has money.                 Negative: Jennie has no money.

The contraction n’t :

  • Sentence: Janetta kisses her mom.   Negative: Janetta doesn’t kiss her mom.

Notice that when forming a negative in the present tense, the helping verb does is what signals the 3rd person singular, and the main verb "kiss" does not have an -es ending.
The following sentences show you the ways to make a sentence negative in the past tense.
  • Sentence: Paul called me yesterday.         Negative: Paul did not call me yesterday.

  • Sentence: Jamilee went to the grocery store.  Negative: Jamilee didn´t go to the grocery store.

  • Sentence: Gina laughed when she saw the huge pile of laundry.  Negative: Gina did not laugh when she saw the huge pile of laundry.
Notice that when forming a negative in the past tense, the helping verb did is what signals the past tense, and the main verb "laugh" does not have an -ed ending.

at Christmas*/EasterI stay with my family at Christmas.

inon
in the morningon Tuesday morning
in the morningson Saturday mornings
in the afternoon(s)on Sunday afternoons
in the evening(s)on Monday evening

Let´s practice now:

Should - Must - Have to

Should - Must- Have to


SHOULD - MUST - HAVE TO

We can use have to + infinitivemust + infinitive and should + infinitiveto express obligation (something you have to do).

PresentPositiveNegative
have to /
don't have to
strong obligation (possibly from outside)
  • Children have to go to school.
(sometimes 'have got to')
no obligation
  • I don't have to work on Sundays.

  • You don't have to eat anything you don't like.
must / mustn'tstrong obligation (possibly based on the speaker's opinion)
  • I must study today.
negative obligation (VERY STRONG)
  • You mustn't smoke here.
should / shouldn'tmild obligation or advice
  • You should save some money.
mild negative obligation or advice
  • You shouldn't smoke so much.

Be careful about the difference between mustn't and don't have to!
Mustn't means it's not allowed, or it's a bad idea:
  • You mustn't eat so much chocolate, you'll be sick
Don't have to means you don't need to do something, but it's fine if you want to do it:
  • I don't have to get up early at the weekend(of course, if I want to get up early, that's fine, but I can stay in bed if I want).
PastPositiveNegative
had to / didn't have toobligation in the past
  • I had to wear a school uniform when I was a child.
no obligation in the past
  • We didn't have to go to school on Saturdays.
must*changes to 'had to'-
should have + pp / shouldn't have + ppa past action which didn't happen: the advice / regret is too late
  • You should have gone to bed earlier, now you have missed the train.
a past action which didn't happen: the advice / regret is too late
  • You shouldn't have taken that job., it was a bad idea.

* Remember 'must have done' is a modal verb of deduction or speculation, not obligation in the past. For example: Julie must have left. Her coat's not here.

There is / there are Some/any


There is / There are - Some / Any



There is / There are

Estas expresiones se utilizan para expresar la cantidad de objetos o personas que se encuentran en un determinado lugar.
Ambas formas significan "Hay". La diferencia es que la primera se utiliza para el singular y la segunda para el plural.

Singular:   There is a chair in the bedroom.                 Hay una silla en el dormitorio.

Plural:   There are two chairs in the bedroom.             Hay dos sillas en el dormitorio.
En el primer caso, se hace referencia a una silla, por lo que debe usarse la forma singular.
En el segundo caso, se hace referencia a más de una silla, por lo tanto se usa la forma plural.

Como norma general, some se aplica en las oraciones afirmativas, mientras que any se usa en las oraciones interrogativas y negativas.
