Wind is the great maker of waves. There are exceptions (例外), such as the tidal (潮汐的) waves sometimes caused by earthquakes under the sea. But the waves most of us know are caused by winds blowing over the sea .
Now let’s learn some physical (自然地理学的) things about it. A wave has height, from low point to high point . It has length (长度)--the distance from this high point to that of the following wave. The period of the wave means the time it takes for succeeding high points to pass a fixed point. None of these things stays the same--for all depend upon (依靠)the wind, upon the depth (深度) of the water and many other matters.
The water that makes up a wave does not advance with it across the sea. Each drop of water turns around in a little circle with the passing of the wave, but returns very nearly to its original position (原先的位置). And it is lucky that this is so. For if the huge groups of water that make up a wave really moved across the sea, sailing would be impossible. If we want to find the speed of a wave, we may use the following way : Speed =" wavelength" × frequency (频率).
Here, wavelength is the distance between two high points , frequency means the number of cycles per second

People with disabilities make up a large part of the population. It is reported that over 35 million Americans have physical, mental, or other disabilities. About half of these disabilities are “developmental", that is to say, they happen before people’s twenty-second birthday, often from born conditions, and are hard enough to affect three or more areas of development, such as movement, communication, occupation, etc. Most other disabilities are considered “adventitious" (偶然的), i.e., accidental or caused by outside forces.
Before the 20th century, only a small percentage of people with disabilities survived for long. Medical treatment for these disabilities was unavailable. Improvements in medicine and social services have created a climate in which people with disabilities can expect to have such basic (基本的) needs as food, shelter, and medical treatment. Unluckily, these basics are often not available. Human rights such as the right to vote, marry, get an education, and achieve work have traditionally been not agreed on the basis of disability.
In recent ten years, the disability rights movement has been organized to fight against these disagreements of human rights. Congress(国会) replied by passing important laws recognizing(承认) people with disabilities as a protected group under human rights laws.
It is reported that more than half of qualified(有资格的) Americans with disabilities don’t have work, and a lot of those who do work are out of work. About two-thirds live at or below the official lowest level.
Obvious difficulties, especially in communication and public awareness(意识), prevent disabled people from taking part in society. For example, while no longer stopped by law from marrying, a person unable to communicate is excluded(排斥) from society and social activities which might lead to the development of long-term relationships.
Only when public attitudes(态度) advance as far as laws have, disabled people will be fully able to take their rightful place in society.
【小题1】. A “developmental" disability ______.
| A.is caused by forces |
| B.happens in youth and affects development |
| C.develops very slowly over time |
| D.is getting harder and harder |
| A.they were not very well looked after |
| B.disabilities destroyed body functions terribly |
| C.they were too poor to get right treatment |
| D.medical treatment were not available |
| A.One | B.Two |
| C.Three | D.Four |
| A.The public tend to(倾向) look down on the disabled people. |
| B.Many disabled people may remain single(保持单身) for their whole life. |
| C.The disabled people feel inferior(不及) to those common people. |
| D.Discriminatory(歧视性) laws prevent the disabled from mixing with others. |
| A.The Causes for Disabilities |
| B.Medical Treatments for Disabilities |
| C.The physical difficulties of the Disabled |
| D.Disadvantages of People with Disabilities |
