假如不去救战士……

抗美援朝时期。在一场异常激烈的战斗中,一架敌机正向阵地俯冲下来。班长正准备卧倒时,突然发现离他四五米远处有一个小战士还在那儿直愣愣地站着。班长顾不上多想,一下子扑了过去,将小战士紧紧地压在身下。一声巨响过后,班长站起身来拍拍落在身上的泥土,正准备教训一下这位小战士时,眼前的情景使他惊呆了:刚才自己所处的那个位置被炸弹炸成了一个大坑。

Maurice Sendak’s children’s book, Where the Wild Things Are, published in 1963, has become very successful throughout the years and was made into a movie earlier this year.

The book’s main character is a boy named Max who gets into trouble with his mother and is sent to bed without any supper. Before long, Max’s room magically becomes a forest, and he sails away to a land where monsters live. Max isn’t scared, though, and becomes king of the wild things, but after a while, he begins feeling homesick. Max sails back home and his supper is still hot when he arrives in his bedroom.

Many teachers and professors like this story and use it to help children develop creativity and imagination. Melina Davis, an education professor, said she likes how the book contains a couple of pages that have only pictures on them. “This allows children to shape the story themselves,” she said.

The book contains a few of larger words that some parents worry may confuse children, but experts say those words help improve children’s reading skills and challenge them.

Davis said the book is well written which helps kids get involved in the story. “The book talks about what all children go through, like ‘I was naughty but my mommy still loves me’,” Davis said.

The book also encourages children to face their fears. “I think it’s really good to show that Max is friends with the monsters,” Davis said. “Kids can find out monsters aren’t always the thing under the bed that’s going to scare them. I think this is good because it shows that the children can go to scary places but still have a positive experience.”

Since the book has been successful throughout the years, a movie was recently made and many people are excited to see it. Davis said she thinks the movie will be wonderful but it might be a little scary for younger children. “You don’t want bad dreams over a book that’s extremely wonderful,” Davis said.
