Now let’s look at how additives can be bad for our health. For example, a little English girl called Sally Jones is two years old and quite ordinary (普通的). But when she was younger, she never went to sleep at night. She never got tired. Her parents were very worried. Finally, Sally’s parents took her to a special doctor.

The doctor said that she must never eat food with additives in it. He was sure that the additives had a very bad effect on her body, and made her too active. He was quite correct. As soon as Sally started to eat foods with no additives, she began to sleep well at night.

Now she is the same as other little girls, except that she can’t eat many foods that other children love, such as ice-creams, because they have additives in them.
