Do you agree with the idea that university students who are caught cheating in exams should be asked to leave school?
I don't think it's appropriate to expel students who are caught cheating in exams. Because everyone deserves a second chance to correct their mistakes, and it's inevitable for ordinary people to make mistakes. The students who are cheating in exams might simply want to get a good grade without having enough time to prepare. I believe the principle of schooling is to educate and discipline people so that they could correct their wrong behavior. If these students have to leave school, then there's no point of educating. Also, I think the punishment is a little bit too harsh on students. Instead, the university could ask them to take the course again next semester, or cancel their scores.
Some college students like to spend their free time studying another course or doing schoolwork. Others like to join a club and enjoy club activities. Which do you think is better and why?
Well, I'd like to spend my free time joining a club and participating in club activities. Because I think I've already spent enough time on studying during the lectures and seminars. It's not necessary to devote my spare time to learn another subject. Then my life would be pretty boring and tiring. However, joining a club could enrich my university life and fully relax myself. For example, I took part in the singing club in my university, and performing in choir concerts provided me with a lot of beautiful memories. I also made many friends in the club, whom I still contact with after graduation. So I'd prefer to join a club and take part in more activities.
In the proposal letter, the student suggests that the university should display more art works in the library rather than the campus gallery. In the conversation, the woman agrees with the idea for two reasons. First, she thinks that the art gallery is located far away from the campus area. Students hardly ever visit there and most of them won't be willing to spend time appreciating art. However, in the school library there are always many students studying or preparing for exams. So it could hugely increase the chances for students to pay attention to the art works once they are shown in the library. Second, she points out that the library is newly established and it lacks of proper ornament. If the university replace these art pieces to the library, they could also serve as beautiful decorations. Thus, the library would look nicer.
In the lecture, the professor uses an example of paradise birds to explain a biology concept. The same species of animals could vary from size to shape, and this type of difference can play an important role in helping the animals survive. For example, male paradise birds and female birds are different in shape and color. Male paradise birds have long feather with beautiful colors. And their body size tends to be larger than the female ones. These features are especially ideal for them to attract female birds to mate with. But it also increases the exposure to predators. On the contrary, female paradise birds have short feather with simple colors. Most of them are brown. And they are comparatively smaller than their male partners. So they are better at taking care of babies and these features enable them to blend into the environment more easily.
The woman is facing a problem, because she needs to go home to see her sister during the summer vacation, but she also wants to take part in a geology trip. There are two possible solutions. First, she can go home to visit her sister. Second, she can take the trip and see her sister next summer. Well, if I were her, I would choose the first suggestion. Because I think when it comes to time conflict, family always goes first. Since her sister is really looking forward to seeing her at home, if she tells her sister that she couldn't make it because of the trip, then her sister will be very disappointed. And also, I think next semester there will be plenty of trips for her to take with her friends. She won't miss anything and may still enjoy herself during the trip.
The use of chemical dye has brought two major benefits to our society. First, clothes fashion has changed since chemical dye became available. Long time ago, people had to use natural dye in cloth production. And it could be really expensive to manufacture colorful clothes. For example, the purple color was made from snails, and it could consume thousands of them to dye cloth. So only wealthy people could afford to wear colorful clothes. But with the development of chemical dye, the cost of making colorful clothes dropped dramatically and more people could be able to buy it. Another positive influence was shown in medical field. Scientists have discovered that a special yellow dye could effectively kill bacteria. By using this kind of chemical dye in medical treatment, doctors could prevent injuries from getting infected. And this has led to a breakthrough in medicine.
