Whether to teach young children a second language is disputed among teachers, researchers and pushy parents. On the one hand, acquiring a new tongue is said to be far easier when young. On the other, teachers complain that children whose parents speak a language at home that is different from the one used in the classroom sometimes struggle in their lessons and are slower to reach linguistic milestones. Would a 15-month-old child, they wonder, not be better off going to music classes
A study just published in the Proceedings of the National Academy of Sciences may help resolve this question by getting to the point of what is going on in a bilingual child’s brain, how a second language affects the way he thinks, and thus in what circumstances being bilingual may be helpful. Agnes Kovacs and Jacques Mehler at the International School for Advanced Studies in Trieste say that some aspects of the cognitive development of infants raised in a bilingual household must be un
A. Parents
B. Teachers

[单项选择]Studies of children’s acquisition of language suggest that the faculty of language includes an inborn knowledge of the formal principles of language structure, a knowledge that depends on generically determined portions of (usually) that left cerebral hemisphere. Although it is well established that the left hemisphere is specialized for language, one cannot say that language is "located" in this or that part of the hemisphere. What is known is that language disorders are the results of lesions in the left hemisphere. Disorders of language resulting from damage to the brain are called aphasias.
The anterior portion of the "language area" is termed Broca’s area. Lesions in this area interfere with the motor and articulatory aspects of language. Speech is slow, labored, grammatically incorrect, and telegraphic; in extreme cases, it may be impossible to carry out. Writing is likewise severely impaired. Comprehension of the spoken or written word, however, may be unimpaired or, nea
A. describing the process of language acquisition
B. explaining potential treatment of language defects
C. showing the importance of the left hemisphere of the brain to language mechanisms
D. depicting various means of diagnosing language defects
