Spontaneous communication and free interaction are possible in any language only when teachers and their students have built up a warm, uninhibited, confident sympathetic relationship and when such a relationship also exists among the students themselves. In the first lessons no such state of affairs exists as yet. The teacher's efforts from the beginning should be devoted to building up such relationships through enjoyable, successful experiences in using interesting and amusing segments of language in a multiplicity of ways.

Under pressure from animal welfare groups, two national science teachers associations have adopted guidelines that ban classroom experiments harming animals. The National Association of Biology Teachers and the National Science Teachers Association hope to end animal abuse in elementary and secondary schools and, in turn, discourage students from mishandling animals in home experiments and science fair projects.
Animal welfare groups are apparently most concerned with high school students experimenting with animals in extracurricular projects. Barbara Orlans, President of the Scientists' Center for Animal Welfare, said that students have been performing surgery at random, testing known poisonous substances, and running other pathology experiments on animals without even knowing normal physiology.
At one science fair, a student cut off the leg and tail of a lizard to demonstrate that only the tail can regenerate, she said. In another case, a student bound sparrows, starved them and observed their behavior.
"The amount of abuse has been quite horrifying", Orlans said.
Administrators of major science fairs are short-tempered over the teachers' policy change and the impression it has created. "The teachers were sold a bill of goods by Barbara Orlans", said Thurman Grafton, who heads the rules committee for the International Science and Engineering Fair. "Backyard tabletop surgery is just nonsense. The new policies throw cold water on students' inquisitiveness", he said.
Grafton said he wouldn't deny that there hasn't been animal abuse among projects at the international fair, but he added that judges reject contestants who have unnecessarily injured animals. The judges have a hard time monitoring local and regional fairs that may or may not choose to comply with the international fair's rules that stress proper care of animals, Grafton said.
He said that several years ago, the Westinghouse Science Talent Search banned harmful experiments to animals when sponsors threatened to cancel their support after animal welfare groups lobbied for change.
The teachers adopted the new policies also to fend off proposed legislation—in states including Missouri and New York—that would restrict or prohibit experiments on animals.
Officials of the two teachers organizations say that they don't know how many animals have been abused in the classroom. On the one hand, many biology teachers are not trained in the proper care of animals, said Wayne Moyer, executive director of the biology teachers' association. On the other, the use of animals in experiments has dropped in recent years because of school budget cuts. The association may set up seminars to teach better animal care to its members.

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
