Dear Editor,
I am a doctor in the Children’s Hospital. I saved a lot of sick children小题1:      Sometimes parents are careless. They put medicine in low(低的)places and their children can get it easily小题2:         They just know it tastes(尝起来) sweet. They may get the medicine and eat it. So parents should put medicine away or keep it in a high(高的)place.
There is also another reason: Children can easily open the medicine bottles(瓶子).
小题3:       He showed me a kind of plastic(塑料的)medicine bottle. We can open it by only pressing down the lid(按下盖子)while turning. 小题4:       However, parents can open it very easily.
Making the bottles is quite easy. 小题5:      And I hope parents can be more careful. Then the children will be safer.
Yours,
Wang Fang

The children don’t know the medicine is dangerous. It is difficult for most children to do so. Many of them were sick because they took some medicine by mistake(错误地). Some days ago I talked about medicine with an American doctor. Many children don’t like eating medicine, for they can’t stand the taste. It is a good way to keep the children away from the dangerous medicine. I think parents are too busy to look after their children.
