necessarily better.
"Until now most of the thinking has suggested that to be a good competitor in the forest,
you have to be a big plant," says Queen"s Biology professor Lonnie Aarssen. "But our research
shows it"s virtually the other way around."
Previous studies showed that larger plant species monopolize(垄断) sunlight, water and
Other resources, limiting the number of smaller plant species that can exist around them. But
the research has proved that this is not generally the case in natural vegetation.
In the Queen"s project, PhD student Laura Keating targeted the largest "host plants" of 16
woody plant species growing in the Okanogan Valley, British Columbia. The research team
calculated the number and variety of plants that neighbored each large host plant. They then
randomly selected plots without host plants and calculated the plant species there as well. The
research showed that the massive trees have no effect on the number of species with which they
coexist.
Smaller plants have many advantages over their overbearing neighbors, Professor Aarssen
notes. Larger species generate physical space niches(生态位)under their shelters where smaller
species grow well. Smaller plants are much more effective than large trees at using available
resources. They also produce seeds at a much younger age and higher rate than their bigger
counterparts, and settle down much more quickly-thus competing with the newly-born plants
of larger species.
B. In the plant world, the bigger is better than the smaller one.
C. To be a good competitor in the forest, you have to be a small plant.
D. Queen"s University"s students made a new research.
B. larger plant species limit their smaller neighbors" growth
C. small plant species have their own advantages
D. large and small plant species can never coexist.
B. surround together
C. evolve together
D. live together

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, bow 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 lab, or 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.

Research has shown that music has an important effect on one"s body and psyche (心灵). In fact, there is a growing field of health care known as music therapy, which uses music to treat diseases. Even hospitals are beginning to use music therapy. This is not surprising, as music affects the body and mind in many powerful ways. Research has shown that quick music can make a person feel more alert, while slow music can produce a calm, deep thinking state. Also, research has found that music can change brainwave activity levels. This can help the brain to change speeds more easily on its own as needed, which means that music can bring lasting benefits to your state of mind, even after you"ve stopped listening. Breathing and heart rates can also be influenced by music. This can mean slower breathing, slower heart rate. This is why music and music therapy can help reduce the damaging effects of long-term stress, greatly promoting (促进) not only relaxation, but health. Music can also be used to bring about a more positive state of mind by helping to keep worries away. Music has also been found to bring many other benefits, such as lowering blood pressure and reducing the risk of strokes. It is no surprise that so many people are considering music as an important tool to help the body become or stay healthy. | |
