Tema 10 — Reading and Use of English
Reading comprehension: antes de leer, mira título, imágenes y subtítulos para predecir el tema (skimming). Busca información específica con scanning (nombres, fechas, cifras).

Use of English: word formation (sad → sadness → sadly), phrasal verbs (give up, look after, carry out), collocations (make a mistake, do exercise, take a decision). Cuidado con los false friends: actually = en realidad, eventually = finalmente.
Conceptos clave:
Skimming: lectura rápida para captar la idea general
Scanning: buscar datos específicos (nombres, números, fechas)
Word formation: prefijos (un-, dis-, re-) y sufijos (-ful, -less, -ment, -tion)
Phrasal verbs: look up, turn on, give up, put off, break down
