Genetically modified (GM) foods are foods made from genetically modified organisms (GMO) that have had their DNA altered through genetic engineering. GM foods were first put on the market in the early 1990s. The most common modified foods are derived from plants: soybean, corn, canola, and cotton seed oil.

Pre-reading Discussion 1 What the difference between ordinary food and GM food? 2 How much GM food is there in China? 3 What are the advantages and disadvantages of GM food? 4 What should we do about GM food in China?

Reading GM food ---- Good or Bad? Not much is known about long- term effects of GM food on humans and the environment. It is “unpredictable”.

Post-reading 3 1 Is transgenic food the same as GM food? Yes. 2 What is the risk of producing a GM crop which kills pests? It will kill good insects as well.

3 Why is the risk from carcinogens reduced in GM food? Because there are fewer traces of cancer-inducing pesticides in the food. 4 What is the risk to someone who is allergic to a particular gene? If that gene is transferred to another food, and the allergic person doesn’t know.

5 How does the amount of GM food in the US compare with the number of people who think it’s dangerous? 30% of maize, 50% of soya beans, 50% of potatoes and tomatoes are GM, and 27% of consumers are worried about the dangers of GM.

Discussion 1 Are you for or against GM food? Explain why. 2 What do you think should be done about GM food in China? Ban the planting of GM crops, ban the sale of GM food, label it clearly, or anything else?
