Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 30 to 34.
In today's competitive world, what responsible parents would not want to give their children the best possible start in life? For this reason, many parents want their children, often as young as ten months old, to become familiar with computers. They seem to think that if their children grow up with computers, they will be better equipped to face the challenges of the future.
No one has proved that computers make children more creative or more intelligent. The truth may even be the opposite. Educational psychologists claim that too much exposure to computers, especially for the very young, may negatively affect normal brain development. Children gain valuable experience of the world from their interaction with physical objects. Ten-month-old babies may benefit more from bumping their heads or putting various objects in their mouths than they will from staring at eye-catching cartoons. A four-year-old child can improve hand-eye coordination and understand cause and effect better by experimenting with a crayon than by moving a cursor around a computer screen. So, as educational psychologists suggest, instead of government funding going to more and more computer classes, it might be better to devote resources to music and art programs.
It is ludicrous to think that children will fall behind if they are not exposed to computers from an early age. Time is too precious to spend with a "mouse". Now is the time when they should be out there learning to ride a bike. There will be time later on for them to start banging away at keyboards.
Children who spend a lot of time on their computers _____.
A.will suffer from brain damage
B.tend to have more accidents than those who do not
C.do not necessarily make more progress than those do not
D.tend to like music and art more than those who do not
