From the reading material, we know that the college is going to add music, dance and sculpture as compulsory courses. the man in the conversation thinks that this is a bad idea. First, he majors in banking and has to take finance class，he has to take the fine art courses, and he would lose some opportunities to choose the courses that he needs. Also, he points out that he doesn’t enjoy sculpture at all, it would help students relax, not everyone has the talent about arts. He has to take these courses, it will be a waste of time and make him stressful.
新托福口语part3中，通常需要考生将主要人物的态度以及两个理由清楚地表达出来，我们可以看到在这个范例中，虽然考生将reading part和listening part 中重要信息都涵盖在答案里，而且没有出现任何明显的语法错误，但是因为缺少必要的逻辑连接词，整个表达给我们一种非常凌乱的感觉，毫无任何连贯和清晰可言。这也是很多考生之所以虽然将笔记记得非常详细，却依然拿不到理想分数的主要原因。
From the reading material, we know that the college is going to add music, dance and sculpture as compulsory courses. However, the man in the conversation thinks that this is a bad idea, due to the following reasons. First, considering that he majors in banking and has to take finance class， he would lose some opportunities to choose the courses that he needs, if he had to take the fine art courses. Also, he points out that he doesn’t enjoy sculpture at all even though it would help students relax, for not everyone has the talent about arts. If he had to take these courses, it would be a waste of time and make him stressful.
The school has implemented a new proposal that they are going to set up a table talk at lunch time in the dining hall, when the professor will be invited to join the lunch. And the woman holds a positive view towards the announcement for the following reasons. First, if the professor could sit with them, the program would provides a chance for the students to ask questions in order to understand the courses, because the professor is normally very busy and although they could use the office hour, it is not enough for all the students to talk to the professor. Another reason is that since she hasn’t known other students very well yet，the table talk could help to enhance the relationship among students , for it would offer a chance for students to communicate and share similar ideas and hobbies.
The school has implemented a new policy that the students will be offered cold breakfast foods instead of hot ones. And the woman is totally against the announcement. The first reason she gives is that although cold foods are usually healthy, hot foods like hot cereal are sometimes even better for health , in case that it’s on cold morning. And the second one is based on the fact that the new policy will make students spend more money instead of saving money. This is because when the students can’t buy foods they want on campus, they’re going to get them off campus, which means they will have to pay more money to get the expensive foods.
