1.
In the United States, 30 percent of the adult population has a "weight problem". To many people, the cause is obvious: we eat too much. But scientific evidence does little to support this idea. Going back to the America of 1910, we find that people were leaner than today, yet they ate more food. In those days people worked harder physically, walked more, used machines much less, and didn't watch TV.
Several modern studies, moreover, have shown that fatter people do not eat more on average than thinner people. In fact, some investigations, such as a 1979 study of 3, 545 London office workers, report that, on balance, fat people eat less than slimmer people.
Studies show that slim people are more active than fat people. A study by a research group at Stanford University found the following interesting fact:
The more the man ran, the greater loss of body fat.
The more they ran, the greater their increase in food intake.
Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.
1).
In comparison with the adult American population today, the Americans of ____.
A、

1970 was World Conservation (保护) Year. The United Nations wanted everyone to know that the world is in danger. They hoped that governments would act quickly in order to conserve nature. Here is one example of the problem. At one time there were 1 300 different plants, trees and flowers in Holland but now only 866 remain. The others have been destroyed by modem man and his technology. We are changing the earth, the air and water, and everything that grows and lives. We cant live without these things. If we continue like this, we shall destroy ourselves.What will happen in the future? Perhaps it is more important to ask "What must we do now?" The people who will be living in the world of tomorrow are the young of today. A lot of them know that conservation is necessary. Many are helping to save our world. They plant trees, build bridges across rivers in forests, and so on. In a small town in the United States a large group of girls cleaned the banks of 11 kilometers of their river.

There are different ways in which people try to deal with the problem of energy. One way is the greater production of common energy sources, such as coal, oil and gas. The trouble with these sources, however, is that they are not renewable.
Another way is energy conservation ( 节能 ), which means using energy more efficiently ( 有效地 ). In some very cold countries people build special houses to save energy. They place materials between the inside and the outside of the walls of the house to keep the cold out and the warmth in. The house is heated by the lights, the body heat of the people and the other equipment in it.
Finally, renewable energy sources are used even though they are often expensive to develop. One form of these is geothermal energy. In certain parts of the world the temperature of the earth increases thirty degrees centigrade with each kilometer down. At six kilometers, therefore, it rises to nearly two hundred degrees. To get the heat, water is pumped ( 压；抽 ) down into the rocks and back up to the surface. Heat from the earth is already used in certain countries.

Jupiter Communications, a market research firm, reports that 72% of teenagers in the United States will be online by 2003 (Stanton, 2000). This alone indicates that students will learn and communicate electronically more than any previous generation. At the same time, teenagers are not the only digital learners. With the growing number of online courses, the increasing accessibility of computers, and the increasing number of computer users, students of all ages are taking advantage of distance learning or are using computers to enhance the traditional classroom experience.
Two things emerge in the study of students’attitudes toward online learning: individual situations impact students’ perceptions of computer-based learning, and students’ varied individual characteristics make it difficult to define their perceptions conclusively. For example, some students have their own computers, while others rely on computer labs. Such variation in computer access can result in attitudinal differences. In addition, the purpose of computer use varies. Distance education courses, for example, use computers in different ways than traditional classrooms, which can also affect students’ perceptions. A wide variety of achievement levels and attitudes exist among both online and traditional learners. Although an illusory “typical learner” exists, a variety of factors, including students’ gender, age, and motivation, could explain different reactions among the student population.
1).
According to the passage, what does "digital learners" mean?
A、
Learners of mathematics.
B、
Learners of information technology.
C、
Computer users.
D、
Online learners.
2).
What will make online learning more and more popular?
A、
The crowded classrooms.
B、
The lower cost of computers.
C、
The increase of computer users.
D、
The previous generations interest in digital communication
3).
Who may become online learners?
A、
Mainly teenagers.
B、
Mostly college students.
C、
Only working people with their own computers.
D、
People of all ages and backgrounds.
4).
Which of the following is the main factor that makes it difficult to define students'' perceptions of online learning definitely?
A、
Learners'' varied locations.
B、
Learners'' varied characteristics.
C、
Learners'' varied communication skills.
D、
Learners'' varied experiences.
5).
What is the author''s attitude towards online learning?
A、
cautious
B、
indifferent
C、
positive
D、
