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.

The men and women of Anglo-Saxon England normally bore one name only. Distinguishing epithets were rarely added. These might be patronymic, descriptive or occupational. They were, however, hardly surnames. Heritable names gradually became general in the three centuries following the Norman Conquest in 1066. It was not until the 13th and 14th centuries that surnames became fixed, although for many years after that, the degree of stability in family names varied considerably in different parts of the country.
British surnames fall mainly into four broad categories: patronymic, occupational, descriptive and local. A few names, it is true, will remain puzzling: foreign names, perhaps, crudely translated, adapted or abbreviated; or artificial names.
In fact, over fifty percent of genuine British surnames derive from place names of different kinds, and so they belong to the last of our four main categories. Even such a name as Simpson may belong to this last group, and not to the first, had the family once had its home in the ancient village of that name. Otherwise, Simpson means "the son of Simon", as might be expected.
Hundreds of occupational surnames are at once familiar to us, or at least recognizable after a little thought: Arther, Carter, Fisher, Mason, Thatcher, Taylor, to name but a few. Hundreds of others are more obscure in their meanings and testify to the amazing specialization in medieval arts, crafts and functions. Such are "Day", (Old English for breadmaker) and "Walker" (a fuller whose job was to clean and thicken newly, made cloth).
All these vocational names carry with them a certain gravity and dignity, which descriptive names often lack. Some, it is true, like "Long", "Short" or "Little", are simple. They may be taken quite literally. Others require more thinking: their meanings are slightly different from the modern ones. "Black" and. "White" implied dark and fair respectively. "Sharp" meant genuinely discerning, alert, acute rather than quick-witted or clever.
Place-names have a lasting interest since there is hardly a town or village in all England that has not at some time given its name to a family. They may be picturesque, even poetical; or they may be pedestrian, even trivial. Among the commoner names which survive with relatively little change from old-English times are "Mil ton" (middle enclosure) and "Hilton" (enclosure on a hill).
Surnames are said to be ______ in Anglo-Saxon England.
A．common
B．vocational
C．unusual
D．descriptive

Is language, like food, a basic human need without which a child at a critical period of life can be starved and damaged？ Judging from the drastic experiment of Frederick Ⅱ in the thirteenth century, it may be. Hop hag to discover what language a child would speak if he heard no mother tongue, he told the nurses to keep silent.
All the infants died before the first year. But clearly there was more than lack of language here. What was missing was good mothering. Without good mothering, ill the first year of life especially, the capacity to survive is seriously affected.
Today no such severe lack exists as that ordered by Frederick. Nevertheless, some children are still backward in speaking. Most often the reason for this is that the mother is insensitive to the signals of the in fact, whose brain is programmed to learn language rapidly. If these sensitive periods are neglected, the ideal time for acquiring skills passes and they might never be learned so easily again. A bird learns to sing and to fly rapidly at the right time, but the process is slow and hard once the critical stage has passed.
Experts suggest that speech stages are reached in a fixed sequence and at a constant age, but there are cases where speech tins started late in a child who eventually turns out to be of high IQ. At twelve weeks a baby smiles and makes vowel-like sounds; at twelve months he can speak simple words and understand simple commands; at eighteen months he has a vocabulary of three to fifty words. At three he knows about 1000 words which he can put into sentences, and at four he knows iris language differs from that of his parents in style. rather than grammar.
Recent evidence suggests that an infant is born with the capacity of speaking. What is special about man's brain, compared with that of the monkey, is the complex system which enables a child to connect the sight and feel of, say, a toy-bear with the sound pattern "toy-bear". And even more incredible is the young brain's ability to pick out an order in language from the mixture of sound around him, to analyze, to combine and recombine the parts of a language in new ways.
But speech has to be induced, and this depends on interaction between the mother and the child, where the mother recognizes the signals in the child's babbling, grasping and smiling, and responds to them. Insensitivity of the mother to these signals dulls the interaction because the child gets discouraged and sends out on- ly the obvious signals. Sensitivity to the child's non-verbal signals is essential to the growth and development of language.
The purpose of the Frederick Ⅱ's experiment was ______.
A．to prove that children are bom with the ability to speak
B．to discover what language a child would speak without hearing any human speech
C．to find out what role careful nursing would play in teaching a child to speak
D．to prove that a child would be damaged without learning a language
