    The strange close understanding between twins is a familiar enough phenomenon. Often they seem to understand each other and share each other' s emotions to such an extent that one suspects some kind of thought communication.

    What is not so widely known is that this special relationship often acts as brake on twins ' intellectual development. As they are partly isolated in their own private world, twins communicate less with adults than do other children. The verbal ability of a four-year-old twin is typically six months behind that of a non-twin. The problem can be particularly severe in an underprivileged family, a one-parent family for example, where there is little stimulation for children anyway.

    Such children, while capable of mutual comprehension in a private language, often remain incomprehensible to outsiders and thus at a severe educational disadvantage. The only solution to the problem. cruel though it may seem, is to separate the twins thus forcing them to acquire ordinary speech helped and guided by sympathetic parents and teachers.

A. They can only understand their own private language.

B. They communicate with outsiders less than non-twins.

C. There is little stimulation for them.

D. Adults don ' t like to talk with them.

7. The author probably feels that twins' problem           .

A. can not be solved because solution is very cruel

B. can be solved because twins will be separated
