     Traditional fairytales (童话) are being given up by parents because they are too scary for their young

children, a study found.

     Research uncovered that one in five parents has got rid of old literature such as Snow White and the

Seven Dwarves and Rapunzel in favor of more modern books.

     One third of parents said their children have been left in tears after hearing the gruesome details of

Little Red Riding Hood.

     And nearly half of mothers and fathers refuse to read Rumplesliltshin to their kids as the themes of the

story are kidnapping and killing.

     Similarly, Goldilocks and the Three Bears was also a tale likely to be left on the book shelf as parents

felt it forgives stealing.

     The survey of 2,000 adults was completed to mark the launch of the hit US drama GRIMM ( 格林

童话剧) , which starts tonight at 9pm on Watch, and sees six drama series based on traditional fairytales.

The survey found a quarter of parents questioned wouldn't consider reading fairytales to their kids.

     And 52 percent of the parents said Cinderella didn't send a good message to their children as it

describes a young woman doing housework all day.

     Steve Hornsey, General Manager of Watch, said: "Bedtime stories are supposed to calm children

down and send them off to sleep soundly.But as we see in GMMM, fairytales can be dark and dramatic

so it's understandable that parents worry about reading them to young children.As adults we can see the

innocence in fairytales, but a five - year - old child could take them too literally.Despite the dark nature of

classic fairytales as we see in GRIMM, good will defeat evil and there is always a moral to the story."

     The study also found two thirds of mums and dads try to avoid stories which might give their children

nightmares.The most popular book read at bedtime is now 'The Very Hungry Caterpillar' by Eric Carle.

     However half of parents said traditional tales are "more likely to have a strong moral message than a

lot of modern kids' books, such as The Gruffato, The Hungary Caterpillar and the Mr. Men books.
