CBC is a famous air company which has over twenty planes carrying passengers and goods, flying along 12 fixed lines all over the world. Its service is very good but some passengers are still not satisfied with it and that is why in 2008 and 2009 the company received letters of complaints from consumers or passengers who pointed out over a dozen kinds of problems which are divided in groups in the following table. Those about passengers’ things carried by the plane are Baggage problems. Consumer service refers to service work which passengers are not satisfied with. Over sales of seats are about the fact that more seats are sold and as a result the plane is too crowded to be safe. Refund（退票）problems appear when passengers fail to receive the money paid back to them because of what they have lost. Fares are problems about the price of tickets.

A. 40%          B. 60%          C. 75%          D. 100%

Directions: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.

This was no ordinary class. The students who came together were all science or engineering professors at Cornell University. They had interrupted their research to accept an invitation to take part in an unusual experiment: “an interesting week of poetry”. This class was part of a study to answer the questions: Why is science difficult for many non-science students?

The students in the poetry class listened to lectures and took notes. They had reading tasks and had to write three short papers. All students noticed one thing—the importance of spoken words. In science and engineering classes, the instructors put tables and drawings on the blackboard. But in this poetry class, the instructors just talked. They didn’t write anything on the board.

The scientists and engineers noticed one similarity between science and poetry. In both subjects, students need to find layers of meaning. Some layers are simple, clear, and on the surface; other layers are deeper and more difficult. This search for different levels of meaning doesn’t happen much in undergraduate science classes, but it is important later, in graduate school. And it is always important in humanities(人文科學(xué)).

Both the poetry instructors and their students learned something about teaching from this experience. One poetry instructor, for example, now sees the importance of using informational charts as he teaches. Most of the scientists agreed on several points. First, humanities classes might help science students to see patterns and decide which information is important. Second, the poetry class was fun. One engineer decided, “We need to change the way we teach engineering to make it an enjoyable experience for students.” But perhaps the most important result of the experience was this: All of the professors began to think about how they teach and how they can teach better.
