If you meet any new words in these sentences, guess the meanings of these words.,What does the word chemist’s mean from the context of the whole sentence? From ‘… medicines sold at the chemist’s…,’ we can known the chemist’s is a place where medicine is sold.,What does the word ‘painkiller’ mean? We can see the word is a compound one. The first part of the word is ‘pain’. And the second part is ‘killer’, so we can know that ‘painkiller’ refers to a kind of medicine that can be used to stop one feeling pain.,Can you guess the meaning of the word ‘prescription’? From ‘… talk to your doctor …’ we can learn that ‘prescription drugs’ are ones that we should be careful taking because they could be dangerous if used incorrectly.,Step 1 A,Listen to a lecture by Dr Gray and write the modal forms the doctor uses.,1.

Do not leave any medicine lying around in the house in case children get them.,must,must not,Tapescript,Dr Grey: I am here today to talk to you about the dangers of taking unnecessary medicines. We live in a world where many things move at a very fast speed, and sometimes people expect their bodies to do things quickly as well. However, you should realize that human bodies are not machines; machines can be fixed in a hurry,when they are broken, but bodies cannot be. Some people run to the chemist’s every time they are ill, asking for a quick cure when their bodies just need some rest. For instance, you do not have to take any medicine for a common cold. You should just get enough sleep, drink a lot of water and keep warm to cure a common cold. People must learn that medicines sold at the chemist’s might be very strong and must be used carefully. Even the,simplest medicines can have serious side effects. Take painkillers as an example. You must not take too many of them as they can damage organs like the stomach and the liver. Another danger of taking unnecessary medicines is that a person could take a dangerous combination of prescription drugs. You should always talk to your doctor before you start mixing medicines. You must also make sure that you know if there are,medicines that your body does not react well to. An additional—and perhaps unexpected— danger of taking unnecessary medications is that there are more bottles of pills in the house, which children could pick up and eat the pills as if they were sweets. This is a very important reason why you must not leave any medicine lying around.,Step 1 B,Read the guidelines of part B and answer the question.,What are antibiotics? What are they used for? Antibiotics are medicines that can be used to damage or stop bacteria that can cause infections.,Step 1 B,Categorize all the sentences according to the table below.,2,1, 5,3, 4, 6, 7,Tapescript,Dr Grey: Now I would like to talk about antibiotics and the dangers of taking them unnecessarily. I will tell you what antibiotics are in case you are not sure. An antibiotic is a medicine that can destroy or stop germs from growing. Antibiotics are used to cure serious infections such as ear,infections, but they do not help with illnesses like colds or the flu, which are not infections. You should remember this the next time you think you can cure a cold quickly with antibiotics. In fact, taking antibiotics unnecessarily can cause antibiotic-resistant bacteria to grow in the body. As a result, when a person who uses antibiotics to cure the flu is seriously ill with infections, the antibiotics may not work.,Worse yet, this person could develop an antibiotic-resistant super virus in his or her own body. The powerful virus can be passed to other people and make them very ill. This is a huge problem in hospitals, where many patients already have weak immune systems, and the super virus can be passed easily from patient to patient. For this reason, you should not go to,hospital unnecessarily if you have a cold or flu that is not very serious. Instead, you should do exercise often and eat well to keep your body healthy without taking medicine.,Step 1 C,Read part C, and take notes on the things that Mr. and Mrs. Tang did wrong.,things Mr. and Mrs. Tang did wrong Mrs. Tang took a lot of painkillers. Mr. Tang gave Mrs. Tang some unknown medicine.,Mr. Tang gave Mrs. Tang some antibiotics he had left from a previous illness. Mrs. Tang took some antibiotics without knowing what they were.,Homework:,Workbook: P.114 C1, C2,
