完形填空。
     It has been argued by some that gifted children should be grouped in special classes. The   1    is based
on the belief that in regular classes these children are held back in their intellectual (智力的) growth by   2    situations that are designed for the  3   children.
     There can be little doubt that  4   classes can help the gifted children to graduate earlier and take their
place in life sooner. However, to take these  5   out of the regular classes may create serious problems.
     I observed a number of  6   children who were taken out of a special class and placed in a   7    class.
In the special class, they showed little ability to use their own judgment, relying   8   on their teachers'
directions. In the regular class, having no worry about keeping up, they began to reflect  9   on many
problems, some of which were not on the school program.

 is more often from parents and teachers than from students, and some of these 12   simply conclude that
special classes should be set up for those who are  13  .Some top students do feel bored in class, but why
they  14   so goes far beyond the work they have in school. Studies have shown that to be bored is to be
anxious. The gifted child who is bored is an   15   child.
