Experts say the problem is not with intelligence or the willingness to work hard. The problem, they say, is that some people's brains process information differently.

By definition, people with learning disabilities are average or above average in their intelligence. But their disorders may affect their ability to gain knowledge and, as a result, limit their success in school or jobs.

Different people can have different kinds of learning disabilities. One person may have difficulty with language development. Another may have problems with reading or writing. Still another may have trouble working with numbers.

People can have more than one disorder, but reading is the most common area of difficulty.

Learning disabilities are neurologicaldisorders that affect the brain's ability to store, process and communicate information. The National Center for Learning Disabilities estimates that fifteen million Americans, or five percent, are affected.

The group says three million students in the United States receive some kind of special help in school because of learning disabilities.

今天我们开始一些列关于学习障碍的报道。

专家们称学习障碍问题无关乎智力和努力学习的意愿。他们说问题出在人们大脑处理信息的方式不同。

根据定义，有学习障碍的人指在智力上处于一般或高于一般水平，大脑紊乱影响了他们获取知识的能力，因此限制了他们在学校和工作中的成就。

不同的人可能会有不同类型的学习障碍。一个人可能在语言能力的发展方面有困难，另一个却可能在读写能力上存在问题。而还有些人做数字相关工作时存在麻烦。

人也有可能出现多种紊乱，但阅读方面的紊乱是学习障碍中最常见间的一种。

学习障碍是一种影响大脑存储、处理、信息交换的神经性紊乱。国家学习障碍研究中心估计占人口5%约1500万的美国人都受到神经紊乱的影响。

这个组织称目前美国有300万学生由于学习障碍症在学校接受着某种形式的特殊帮助。
