Certainly no creature in the sea is odder than the common sea cucumber. All living creatures, especially human beings, have their peculiarities, but everything about the little sea cucumber seems unusual. What else can be said about it is: a bizarre animal that, among other eccentricities, eats mud, feeds almost continuously day and night but can live without eating for long periods, and can be poisonous but is considered supremely edible by gourmets.
For some fifty million years, despite all its eccentricities, the sea cucumber has subsisted on its diet of mud. It is adaptable enough to live attached to rocks by its tubefeet, under rocks in shallow water, or on the surface of mud flats.
Common in cool water on both Atlantic and Pacific shores, it has the ability to suck up mud or sand and digest whatever nutrients are present.
Sea cucumbers come in a variety of colors, ranging from black to reddish-brown to sand-color and white. One form. even has vivid purple tentacles. Usually the creatures are cucumber-shaped hence their name and because they are typically rock inhabitants, this shape, combined with flexibility, enables them to squeeze into crevices where they are safe from predators and ocean currents.
Although they have voracious appetites, eating day and night, sea cucumbers have the capacity to become motionless and live at a low metabolic rate — feeding sparingly or not at all for long periods, so that the marine organisms that provide their food have a chance to multiply. If it were not for this faculty, they would devour all the food available in short time and would probably starve themselves out of existence.
But the most spectacular thing about the sea cucumber is the way it defends itself. Its major enemies are fish and crabs. When attacked, it squirts all its internal organs into the water. It also casts off attached structures such as tentacles. The sea cucumber will eviscerate and regenerate itself when it is attacked or even touched; it will do the same if the surrounding water temperature is too high or if the water becomes too polluted.
The passage mainly discusses
A．the reason for the sea cucumber's name.
B．what makes the sea cucumber unusual.
C．how to identify the sea cucumber.
D．places where the sea cucumber can be.

Botany, the study of plants, occupies a peculiar position in the history of human knowledge. For not many thousands of years it was the one field of awareness about which humans had anything more than the vaguest of insights(了解). It is impossible to know today just what our Stone Age ancestors knew about plants. But from what we can observe of pre-industrial societies that still exist, a detailed learning of plants and their properties must be extremely ancient. This is logical. Plants are the basis of the food pyramid for all living things, even for other plants. They have always been enormously important to the welfare of peoples, not only for food, but also for clothing, weapons, tools, dyes, medicines, shelter, and a great many other purposes. Tribes living today in the jungles of the Amazon recognize literally hundreds of plants and know many properties of each. To them botany, as such, has no name and is probab-ly not even recognized as a special branch of "knowledge" at all.
Unfortunately, the more industrialized we become, the farther away we move from direct contact with plants, and the less distinct our knowledge of botany grows. Yet everyone comes unconsciously on an amazing amount of botanical knowledge, and few people will fail to recognize a rose, an apple, or an orchid. When our Neolithic ancestors, living in the Middle East about 10,000 years age, discovered that certain grasses could be harvested and their seeds planted for richer yields the next season, the first great step in a new association of plants and humans was taken. Grains were discovered and from them flowed the marvel of agriculture: cultivated crops. From then on, humans would increasingly take their living from the controlled production of a few plants, rather than getting a little here and a little there from many varie-ties that grew wild and the accumulated knowledge of tens of thousands of years of experience and intimacy with plants in the wild would begin to fade away.
It is assumed in the passage that early humans ______.
A．probably had extensive knowledge of plants
B．thought there was no need to cultivate crops
C．did not enjoy the study of botany
D．placed great importance on the ownership of property

A lawyer friend of mine has devoted herself to the service of humanity. Her special area is called "public interest law". Many other lawyers represent only clients who can pay high fees. All lawyers have had expensive and highly specialized training, and they work long, difficult hours for the money they earn. But what happens to people who need legal help and cannot afford to pay these lawyers' fees？
Public interest lawyers fill this need. Patricia, like other public interest lawyers, earns a salary much below what some lawyers can earn. Because she is willing to take less money, her clients have the help they need, even if they can pay nothing at all.
Some clients need legal help because stores have cheated them with faulty merchandise. Others are in unsafe apartments, or are threatened with eviction (being driven) and have no place to go. Their cases are all called "civil" cases. Still others are accused of criminal acts, and seek those public interest lawyers who handle "criminal" cases.

Of the many problems in the world today, none is as widespread, or as old, as crime. Crime has many forms, including crimes against property, person, and government. Crime, in all its forms, penetrates every layer of society and touches every human being. You may never have been robbed, but you suffer the increased cost of store- bought items because of others’shoplifting.
Your house is not worth as much today as it was a few years ago because of the increased crime rate in your neighborhood. Perhaps your business is not doing as well as it used to because tourism is down due to increased terrorism in your part of the world.
Crime, especially violent crime, has risen to a point where many people are afraid to walk al one in their own neighborhoods, afraid to open their door after dark, afraid to speak out and voice their own opinions. Some citizens have reacted by arming themselves with various weapons, legal and illegal, to defend themselves. Citizen groups have taken the law into their own hands by forming their own vigilante groups to administer judgment when they feel that their criminal justice system has not performed its duty.
Experts argue whether the number of crimes committed is actually on the rise or whether there is simply a rise in the number of crimes reported. This issue is particularly true in cases of marriage violence, the abuse of spouse or children. Throughout much of history, cases of family violence and neglect often went unreported because of the attitude of society, which considered family matters to be private.
Other experts argue about who is really to blame for criminal behavior. the individual or society. Researchers in the United States and Canada have identified several factors in society that contribute to the crime rate: massive urbanization, unemployment and poverty, and a large immigrant population. Other countries are more affected by factors such as politics, government corruption, and religion.

A、To show the criminal justice system is not just
B、To show citizens are powerful in combating crimes
C、To show crime is a serious social problem
D、To show citizens have rights in combating crimes
