Task 1

　　Which one of the following do you think the university should reward? Volunteer service, athletic achievement or academic performance?

　　Task 2

　　Which courses do you think schools should offer to students? Language courses or computer courses?

　　Task 3

　　The university is planning to have a contest among dorms. They’re going to monitor the power use of dorms and the dorm that uses the least amount of electricity wins. The woman agrees with the plan. In the first reason, she thinks this can remind all students of saving power and living an eco-friendly life, like turning off the lights when leaving the room. As for the second reason, the woman points out that even if not everyone will take this contest seriously, most of people will still enjoy it, and with the award, they can go for a delicious meal. So this whole plan will work and encourage people to save energy.

　　Task 4

　　In the lecture, the professor talks about the concept of restrain bias which means sometimes people overestimate their ability to resist temptation. He offers us an example of his daughter. She’s kind of a shopaholic and spends pretty much every penny of hers on buying clothes. Once she wanted to go on a trip with her friends so she made up her mind to save up for it. She was confident at first and said she could definitely control herself and she even started doing some part-time jobs to save money. But then her friends asked her to go shopping, she said she wouldn’t buy anything in the beginning and she would only window shop, however in the end she couldn’t resist the temptation and ended up spending all her savings.

　　Task 5

　　The woman’s problem is that she needs to write a 20-page paper but she needs to move out of her dorm soon, so she doesn’t have a place to finish her paper. There are two possible solutions. The first one is to move in with her parents. And the second solution is to rent an apartment off campus. If I were in her shoes, I would go for the first solution because I’m sure her parents would love to have her, and they would do everything they could to make sure she has a quiet environment to study. I personally don’t recommend the other solution because it’s 400 dollars for two weeks, that’s way too much money for a student, it’s not wise to spend this amount of money on housing when she could easily live with her parents for free.

　　Task 6

　　In the lecture, the professor talks about two ways that animals use ultraviolet light to survive. In the first example, the professor introduces pigeons. Pigeons use ultraviolet light to determine the position of the sun and locate themselves. They can even fly in the rain with this technique. The second example is about honey bees, flowers can reflect ultraviolet light, honey bees can locate the nectar of flowers based on that. That’s how the professor uses the two examples to illustrate the role ultraviolet light plays in animals’ survival.
