According to the passage, the most important aspect of the land is the place ().

A.of beautiful mountains and plains
B.that can grow corn and wheat
C.that can grow plants
D.where cities are built

A.
The study of ecology is important for everyone who cares about our world. Air, water, and land -- we would not live without any of these. But what do we mean by land It is the earth beneath our feet, wherever we are. It is mountains and plains. It is wide fields for growing com and wheat. Or it may be an airfield or a parking lot or a highway or a whole city -- land covered with cement, asphalt, and buildings. Land is the solid part of the Earth.
B.
Land is the soil plants grow in. That is the most important things about the land -- it is the place where green plants grow. Without green plants there would be not life on Earth. Green leaves make oxygen. All of us -- ants, elephants, people, every living creature -- must have oxygen to stay alive. We breathe in oxygen and our bodies use it. Carbon dioxide is formed in the process and we breathe it out. Leaves use carbon dioxide along with water to make food for plants. Then they give off oxygen.
C.
This process has been going on for millions of years. It is part of the pattern of our natural life on Earth. This pattern had changed very little for millions of years before people arrived on Earth. People found ways to improve their lives by changing nature, by trying to make nature fit in with their way of life. Warm houses in winter, electric lights at night, factories to produce our food, our clothes, our gadgets(零用品) -- all this people have accomplished. And we learned to grow more food on the land than nature could grow without our help.
D.
All this is good -- up to a point. But it has gone too far. We have produced too much and we have failed to see what this was doing to our world. We have not understood the ways in which all living things on Earth depend on one another. We ourselves have increased until the sheer numbers of people on Earth have upset the balance of nature.

【单选题】The women’s liberation movement (). A.is concerned only with concrete problems B.is concerned with attitudes and beliefs C.would help women improve their standards of living D.would help women get job...

A.
There are many aspects of the women’s liberation movement. Some women agree with all of the goals of women’s liberation. They want full equality with men in every aspect of life. In marriage, they want husbands and wives to share all of the work and responsibilities of a home and family. In work, they want women and men to have the same jobs and the same chance to succeed. They want women to be paid just as much as men are for the same work. Other women agree with some of the ideas of women’s liberation. They want the same pay if they hold the same job as a man. At home, however, they do not expect their husbands to share in the cleaning, cooking, and other household jobs.
B.
It is important to remember that the women’s liberation movement is not concerned only with concrete issues. The movement is also concerned with attitudes and beliefs. One example of this concern is the issue of a woman’s identity. A woman’s identity is what she thinks of herself as a person, who she thinks she is, and what she thinks she can do. Some women do not think they are capable of doing anything important, The women’s liberation movement would like to help these women improve their view of themselves. Mary women who are concerned with women’s liberation have taken jobs, have helped others, have raised healthy children, and have done many other things to contribute to their communities. They have shown that they are capable of being good leaders and of doing many important things.
