问题     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【C1】______experiment of Frederick II in the thirteenth century, it may be. Hoping 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【C2】______of language here. What was missing was good mothering. Without good mothering, in the first year of life especially, the【C3】______to survive is seriously affected.
    Today no such severe lack exists as that ordered by Frederick.【C4】______, some children are still backward in speaking. Most often the reason for this is that the mother is insensitive to the【C5】______of the infant, whose brain is programmed to learn language rapidly. If these sensitive periods are neglected, the【C6】______time for acquiring skills passes and they might never be learned so【C7】______again. A bird learns to sing and to fly rapidly at 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【C8】______age, but there are cases where speech has started late in a child who eventually turns out to be of high IQ. At twelve weeks a baby smiles and makes vowel-like【C9】______; at twelve months he can speak simple words and understand simple commands; at eighteen months he has a【C10】______of three to fifty words. At three he knows about 1,000 words which he can put into sentences, and at four his language differs from that of his parents in style rather than grammar.
A)ideal B)dialects C)signals D)late
E)capacity F)memory G)vocabulary H)drastic
I)Nevertheless J)cries K)sounds L)constant
M)Consequently N)lack O)easily
【C8】
选项
答案L
解析 此处应填形容词。该句意为“专家认为学习语言的阶段是固定有序的，而且在 年龄”，所缺形容词应该和fixed为同义词。而不是指late“较晚的年纪”，选项中constant表示“恒定的，固定的”，放在句中合适。
