单选题What does the man offer to do?

单选题It is often difficult for a man to be quite sure what tax he 9ught to pay to the government be-cause it depends on so many different things: whether the man is married; how many children he has; whether he supports any relations; how much he earns; how much interest he receives; how much he has spent on his house during the year, and so on and so forth. All this makes it difficult to decide exactly how much the tax is. There was a certain artist who was always very careful to pay the proper amount. One year, after posting his check as usual, he began to wonder if he had paid enough, and after a lot of work, with a pencil and paper, he decided that he had not. He believed that he owed the government something. He was just writing another check to send to the tax-collector when the postman dropped a letter into the box at the front door. Opening it, the artist was surprised to find inside it a check for five pounds from the tax-collector. The official explained that too much had been paid, and that therefore the difference was now returned to the taxpayer.

单选题Why did Carol decide to be an opera singer?

单选题Normally a student should attend a certain number of classes to graduate, and each lesson which he attends offers him a credit (学分) which he may count towards a degree. In a lot of American universities the total work for a degree consists of six courses each lasting for one term. A typical course consists of four classes per week; normally a student would expect to take four years attending two terms each year. It is possible to spread the period of work for the degree over a longer period. It is also possible for a student to move between one university and another during his degree course, though this is not in fact done as a regular practice. For each course that follows a student is given a grade, which is recorded, and the record is available for the student to show to prospective employers. All this imposes a sustainable pressure and strain of work, but despite of this, a few students still find time for great activity in student affairs. Elections to positions in student organization arouse much enthusiasm. The effective work of maintaining discipline is often performed by students who advise the academic authorities. Any student who is thought to have broken the regulations, for instance, by cheating has to appear before a student court. With a great number of students, the operation of the system does involve a certain number of activities. A student who has held one of these positions of authority is much respected and it will be beneficial to him later in his career.
