Pre-reading Interactive Task 1: Answer the questions Write your thoughts about the following questions down below. 1. When you make food choices, what do you take into consideration? Possible answers： Student A: When I make food choices, I think convenience is the most important. That’s why I like eating out. I don’t have to worry about cooking and washing dishes. All I need to do is relax and enjoy the food you order. Student B: I pay more attention to taste. It’s one of the most obvious factors which has great influence on choosing one type of food over another. The term “taste” does not only refer to the way food tastes, but also includes the smell, appearance and texture of the food. Usually, foods that are rich and delicious are more appealing to me. Student C: When I choose food, I take health into consideration. I buy low-fat and low-sugar food to reduce my calorie intake and maintain good health.
