Teaching a child to read at a young age gives him a valuable start in life. Reading is the basic part of education and a child’s reading ability will influence his school success greatly. Learning difficulties, many of which begin from poor reading skills, can damage a school child’s confidence and affect his future achievement. Young children are programmed to learn and they can learn better with encouragement. Ten to twenty minutes of reading a day still leaves plenty of time for play.

Many parents are concerned that learning to read is too challenging a task for a pre-school child, but they should also remember that most children learn to speak by the time they are 3. Learning a language is probably the single most challenging task any individual can undertake, yet children do it without formal instruction, achieving the fluency much better than adult language students.

There is a window of opportunity in terms of IQ development, which is most open during a child’s early years. A scientific study, carried out by Dr. Peter Huttenlocher at the University of Chicago, showed that the number of connectors, called synapses（神经元突触）, between the nerve endings in a newborn baby’s brain is similar to the number in the average adult brain. These synapses increase rapidly during early childhood. By 12-24 months a child’s brain has about 50% more synapses than the average adult brain. After that the synapses which are not in use begin to atrophy（衰退）. For most people, from age 16, the number remains steady. It begins to drop again as we move into our golden years. Doing intellectual activities at a young age, such as learning to read, can stimulate（刺激）and preserve these connectors in the brain resulting in a long-term beneficial（有益的）effect on IQ development.

Another notable study is probably the Milwaukee project. This study took a group of babies, all of whose mothers had low IQs, and gave them special training for seven hours a day, five days a week, until they started first grade. By the age of 6 these children had an average IQ 30 points higher than their contemporaries. The overwhelming conclusion is that the early intellectual stimulation can have a positive, long-term effect on a child’s brain development.

From birth you should talk to and explain things to your baby. Reading to him can be a wonderful way of spending quality time with your child. The enjoyment of books and being familiar with the idea of print will pave the way for（为……铺平道路）learning to read later.

If your child is a fast learner you can help him realize his potential by introducing him to the joy of the printed word at an early age. This will lay the foundations（基础）for both a high achieving school career and a lifelong love of reading. If your child shows early signs of reading difficulties, your efforts may help him get rid of such problems before he goes to school.

It can be difficult to teach your own child because emotional（引起情绪激动的）issues arise easily. Online programs for learning to read English are excellent options. They allow children to repeat new materials as many times as they need to, without wearing out the parents’ patience.
