     CONDITIONAL SENTENCES



   Put the verbs in brackets into a suitable form.


13 Examples:
   If you would like11 a bottle of washing-up liquid, I can give you one.
   If you like, I can give you a bottle of washing-up liquid.


   If you would like takes an object. When the object is not mentioned would must be removed. In other words, if you like is not followed by anything.

a  If you (like), I can lend you a bottle of washing liquid.
b  If you (like) a bag of washing powder, I'll give you one.
c  They may take tomorrow off if they (like).
d  I'll buy you a drink if you (like).
e  If you (like) to take early retirement, we can see to it.


14 Examples: (inversion12)
   Should you see the enemy, keep still. (= If you should see the enemy, keep still.)
   Were I to divorce, I would/should marry again. (= If I were to divorce, I would/should marry again.)
   Had you told me before, I would/should have helped you. (= If you had told me before, I would/should have helped you.)

   As has been seen in the examples above, we can place should, were or had before the subject to mean if. This construction is more formal than the one with if.

a  I (be) you, I would resign.
b  I (be) to be given the job, I would accept it.
c  You (require) any further information, please do not hesitate to contact us.
d  You (apply) for the post, you would have obtained it. It is a pity that you did not.
e  You (inform) us earlier, we could have aided you in your research.


15 Examples: (special cases13)

   Paula refuses to take the exam, she won't get her degree.)
   If you will/would14 give us your address and telephone number, we shall15/will contact you as soon as possible. (= Please give us your address and telephone number, and we shall/will contact you as soon as possible/Will [or "Would"] you please give us your address and telephone number so that we can contact you as soon as possible?)
   I should/would be very grateful if you would send me some information about your courses in Great Britain. (Please send me some information about your courses in Britain.)
   If you will play truant, we will/shall expel you from this school. (If you do not stop playing truant, we will/shall expel you from this school.)

   If you have a breakedown, take this telephone number from the glove compartment.
   In case of war, you should leave the country.
   If war breaks out/If there is a war, you should leave the country.


   In the first instance, you "take the telephone number with you" because you might have a breakdown. In the second example, you perform the action only when this happens; but this may not occur, in which case, you do not "take this telephone number from the glove compartment". The third and fourth sentences above have similar meanings.
