How to use these words well

  • Learn word partners: say a balanced diet and chronic disease, not a balance food or long disease.
  • Use chronic, contagious and preventive in Task 2 to sound precise, but only when the meaning fits.
  • In Speaking, give a personal example after the phrase, such as how you recovered from a cold.
  • Do not describe medical details you are unsure of; a general, accurate statement scores better than a risky one.
