Improving Dormitory Kitchen Use
I’ve noticed that most students don’t use the dormitory kitchens, which is unfortunate since students would probably enjoy preparing their own food. I think that the university should make improvements to the dormitory kitchens so that they will be more widely used. There are a few things that the university could do to encourage students to start using the kitchens regularly. First: I think the kitchens should be modernized with new cookware for students to use. Also, I think free cooking classes should be given to stimulate students’ interest in cooking and make them want to use the kitchens.

Task3：
Explain how the example of the eastern grey squirrel illustrates the concept of deceptive caching
Deceptive Caching
When food is plentiful, animals often collect and hide extra food to eat when it is scarce. However, other animals may try to steal this stored food: and eat it themselves. To protect their food supply, some animals engage in deceptive caching. Using this technique: animals deceive other animals into thinking that food is hidden in one place： while it is actually hidden somewhere else. Deceptive caching tricks animals that try to steal food, making it harder for them to find the food supply. If their attempts at stealing food are repeatedly unsuccessful, the animals often become discouraged and stop trying to steal hidden food.
