Task2:
Hot Breakfasts Eliminated
阅读材料
Hot Breakfasts Eliminated
Beginning next month, Dining Services will no longer serve hot breakfast foods at university dining halls. Instead, students will be offered a wide assortment of cold breakfast items in the morning. These cold breakfast foods, such as breads, fruit, and yogurt, are healthier than many of the hot breakfast items that we will stop serving, so health-conscious students should welcome this change. Students will benefit in another way as well, because limiting the breakfast selection to cold food items will save money and allow us to keep our meal plans affordable.
问题
The woman expresses her opinion of the change that has been announced. State her opinion and explain her reasons for holding that opinion.
Task3：
Cognitive Dissonance
阅读材料
Cognitive Dissonance
Individuals sometimes experience a contradiction between their actions and their beliefs－between what they are doing and what they believe they should be doing. These contradictions can cause a kind of mental discomfort known as cognitive dissonance. People experiencing cognitive dissonance often do not want to change the way they are acting, so they resolve the contradictory situation in another way, they change their interpretation of the situation in a way that minimizes the contradiction between what they are doing and what they believe should be doing.
问题
Using the example discussed by the professor, explain what cognitive dissonance is and how people often deal with it.
