单选题Large modern cities are too big to control. They impose their own living conditions on the people who inhabit them. City-dwellers are obliged by their environment to adopt a wholly unnatural way of life. They lose touch with the land and rhythm of nature. It is possible to live such an air-conditioned existence in a large city that you are barely conscious of the seasons. A few flowers in a public park (if you have the time to visit it) may remind you that it is spring or summer. A few leaves clinging to pavement may remind that it is autumn. Beyond that, what is going on in nature seems totally irrelevant. All the simple, good things of life like sunshine and fresh air are at a premium. Tall buildings blot out the sun. Traffic fumes pollute the atmosphere. Even the distinction between day and night is lost. The flow of traffic goes on unceasingly and the noise never stops.

单选题What does a man do when he can't get exactly what he wants?

单选题 Since there is such an abundance of food in the sea, it is understandable that some of the efficient, highly adaptable, warm-blooded mammals(哺乳动物) that evolved on land should have returned to the sea. Those that did have flourished. Within about 50 million years — no time at all, geologically speaking — one of the four kinds of mammals that have returned to a marine environment has developed into the largest of all animal forms, the whale. A second kind, the seal, has produced what is probably the greatest population of large carnivorous mammals on Earth. This suggests that these "top dogs" of the ocean are prospering and multiplying. However, such has not been the case, at least not for the last 150 years. Trouble has closed in on these mammals in the form of equally warm-blooded and even more efficient and adaptable predators, humans. At sea, as on land, humans have now positioned themselves on the top of the whole great pyramid of life, and they have caused serious problems for the mammals of the sea. There is a simple reason for this. Marine mammals have the misfortune to be swimming aggregates of commodities that humans want: fur, oil and meat. Even so, they might not be so vulnerable to human depredation if they did not, like humans, reproduce so slowly. Every year humans take more than 50 million tons of fish from the oceans without critically depleting the population of any species. But the slow-breeding mammals of the sea have been all but wiped out by humans seeking to satisfy their wants and whims.

单选题Learning how to turn in homework assignments on time is one of the invaluable skills that college students can take with them into the working world. Though the workforce may not assign homework to its workers in the traditional sense, many of the objectives and jobs require that employees work with deadlines. The deadlines that students encounter may be different in content when compared to the deadlines of the workforce, but the importance of meeting those deadlines is the same. Failure to meet deadlines in both the classroom and the workforce can mean instant termination. For example, in the classroom, students form a contract with the teacher and the university when they enroll in a class. That contract requires that students complete the assignments and objectives in a specified time to receive a grade and credit for the course. Accordingly, just as a student risks termination in the classroom if he/she fails to meet the deadline for a homework assignment, so, too, does that student risk termination in the work force. When a student fails to complete those assignments by the deadline, the student breaks his/her contract with the university and the teacher to complete the assignments and objectives of the course. This often leaves the teacher with no other recourse than to fail the student and leaves the university with no other recourse than to terminate the student's credit for the course. Developing good habits of turning in assignments in class now, as current students, will aid your performance and position as future participants in the working world.
