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 in 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 labor laboratory, 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.
1.The main purpose of this text is__________.
A.to help the students to learn about university life

A.spend about 5 hours on lectures each week
B.must join the students in the discussion sections
C.prefer to use textbooks in their lectures
D.require the students to read beyond the textbooks
3.A discussion section does NOT include__________.
A.working under the guidance of university professors
B.talking over what the students have read about the courses
C.discussing the problems related to the students’ homework
D.raising questions about what a professor has said in a lecture
4.According to the author, science majors__________.
A.have to work harder than non-science majors

Since the 1970s,scientists have been searching for ways to link the brain with computers.
Braincomputer interface (BCI) technology could help people with disabilities send commands
to machines.
Recently,two researchers,Jose Millan and Michele Tavella from the Federal Polytechnic
School in Lausanne,Switzerland,demonstrated(展示)a small robotic wheelchair directed by
a person's thoughts.
In the laboratory,Tavella operated the wheelchair just by thinking about moving his left or
right hand.He could even talk as he watched the vehicle and guided it with his thoughts.
"Our brain has billions of nerve cells.These send signals through the spinal cord(脊髓)to
the muscles to give us the ability to move.But spinal cord injuries or other conditions can
prevent these weak electrical signals from reaching the muscles,"Tavella says."Our system
allows disabled people to communicate with external world and also to control devices."
The researchers designed a special cap for the user.This head cover picks up the signals
from the scalp(头皮)and sends them to a computer.The computer interprets the signals and
commands the motorized wheelchair.The wheelchair also has two cameras that identify objects
in its path.They help the computer react to commands from the brain.
Prof.Millan,the team leader,says scientists keep improving the computer software that
interprets brain signals and turns them into simple commands."The practical possibilities that
BCI technology offers to disabled people can be grouped in two categories:communication,
and controlling devices.One example is this wheelchair."
He says his team has set two goals.One is testing with real patients,so as to prove that this
is a technology they can benefit from.And the other is to guarantee that they can use the
technology over long periods of time.
