Transformation exercises- 1

Transformation exercises:

Se trata de lo siguiente: Dada una primera oración base y una determinada palabra, el objetivo es producir una segunda frase que tenga el mismo o similar significado que la primera, pero usando la palabra dada, que no debe cambiarse en ningún caso. Por ejemplo:
a.- I haven't seen her for twenty years
b.- I haven't seen her since 1993

a.- I'd prefer to stay at home tonight
b.- I'd rather stay at home tonight

a.- I've kept the receipt for the shirt because it may not fit you
b.- I've kept the receipt for the shirt in case it doesn't fit you

Estos transformation exercises son muy útiles para profesores y examinadores para comprobar el nivel de los alumnos, y para los propios alumnos para repasar las estructuras gramaticales, el léxico, los modismos, etc. y para preparar exámenes de nivel B-1 o B-2, como 4º y 5º de Escuelas Oficiales de Idiomas o el Cambridge First Certificate in English Examination, más conocido como FCE (First Certificate English).
Los ejercicios de transformación se usan especialmente para repasar algunos de los siguientes temas:
- verbos + infinitivo con to/verbos + forma en -ing: to decide to do sth/to enjoy doing sth
- verbo +  infinitivo con to/ verbo + infinitivo sin to: to allow sb to do sth/to let sb do sth
- verbos + preposición: to borrow sth from sb/to lend sth to sb
- paso de oraciones activas a pasiva o viceversa: they cancelled the show/the show was cancelled
- to do sth/to have sth done: I cut the grass/I had the grass cut
- paso de estilo directo a estilo indirecto: "Can you help me?" the old lady asked me/The old lady asked me if I could help her
- verbos modales y semi-modales: needn't/not to have to: you needn't do it/you don't have to do it
- verbos frasal/ sinónimo no-frasal: to come into sth/to inherit sth; to get sb down/to depress sb
- oraciones condicionales, esp. las llamadas third conditionals: it rained, so we didn't go to the beach/we would have gone to the beach if it hadn't rained
- for/since: for two hours/since seven o'clock
- too/enough: too narrow/not wide enough
-so + adjetivo/such (a/an) + nombre: He's so old/he's such an old man
- distintas construcciones con I wish: I wish you told me/I wish you had told me/I wish you wouldn't be so reserved
- distintas construcciones con I'd rather: I'd rather leave now/I'd rather you left
- modismos y construcciones idiomáticas: it doesn't matter/it doesn't make any difference
