### sense in the lessons

In health and science, antibiotics work against bacteria but not against viruses, so they do not cure colds or flu. Doctors prescribe them only when needed. You must take them exactly as the doctor says and finish the whole course, even if you feel better, so the bacteria do not come back stronger. Overusing antibiotics helps bacteria become resistant, so the medicines stop working. The first antibiotic, penicillin, was discovered by Alexander Fleming from a mould. Phrases: "a course of antibiotics", "on antibiotics", "antibiotic cream", "antibiotic resistance".

Use "an": an antibiotic. "Anti" means against, "bio" means life. Common trap: antibiotics do not kill viruses. Only take medicine from a trusted adult and as the doctor or label says.
