Since many of you are planning to study at a college or university in this country, you may be curious to know what you usually do in a typical week, how you can get along with your fellow students, and so on. These are the questions I want to discuss with you today.
First, let's talk about what your weekly schedule will look like. No matter what your major may be, you can expect to spend between four and six hours a week for each class attending lectures. Lectures are usually in very large rooms because some courses such as introduction to sociology or economics often have as many as two or three hundred students, especially at large universities. In lectures, it's very important for you to take notes on what the professor says because the information a lecture is often different from the information in your textbooks. Also, you can expect to have exam questions based on the lectures. So it isn't enough to just read your textbooks; you have to attend lectures as well. In a typical week you will also have a couple of hours of discussion for every class you take. The discussion section is a small group meeting usually with fewer than thirty students where you can ask questions about the lectures, the reading, and the homework. In large universities, graduate students, called teaching assistants, usually direct discussion sections.
If your major is chemistry, or physics, or another science, you'll also have to spend several hours a week in the lab, doing experiments. This means that science majors spend more time in the classroom than non-science majors do. On the other hand, people who major in subjects like literature or history usually have to read and write more than science majors do.

单项选择题

（A）
Daniel Olin was 11 years old when his parents moved to Canada. He liked his new school and made friends there, but then things at home started to change. His mum and dad began to argue and the arguments got worse and worse until one day, Daniel's mum left. With his father working long hours, Daniel felt very lonely and very unhappy. He wanted to escape, to run away. And that's what he did.
Very early one terribly cold morning when the snow was deep on the ground, he packed a bag with some clothes, some chocolate and a map of Canada and set off to a forest. He ran and ran until he could hardly breathe. His feet were heavy with the snow but he still walked on through deep snow, not even watching where he was going.
Then, disaster struck. A rock hidden by the deep snow caught his feet and Daniel fell to the ground. He had broken the bone. He was very cold and was starting to feel tired, but he knew that if he fell asleep in the snow, he would certainly die from the cold.
A tree shook ahead. From within the branches, a pair of yellow eyes watched Daniel. The puma had been following him. A puma is a large wild cat with claws that could tear Daniel into pieces. But instead of moving in for the kill, the puma walked up to Daniel and lay across his chest, arms and legs. Daniel was too frightened to move, but soon the warmth of the animal reached Daniel and he began to feel better. From time to time, the puma pressed his muzzle (口鼻) against Daniel and rocked his head gently. Clearly, the puma knew that Daniel must not fall asleep. This animal should have been a real danger to Daniel and yet the boy began to feel safe.
They remained like that for several hours until Daniel and the puma heard voices. The rescue team had found them.
