[唐]柳宗元
久为簪组②累，幸此南夷谪。闲依农圃邻，偶似山林客。
晓耕翻露草，夜榜③响溪石。来往不逢人，长歌楚天碧。
[注]①元和五年（810），柳宗元在零陵西南游览时，发现了曾为冉氏所居的冉溪，因爱其风景秀丽，便迁居此地，并改名为愚溪。这首诗就是柳宗元贬官永州居处冉溪之畔时的作品，写他迁居愚溪后的生活。②簪组：古代官吏的冠饰。③榜： 用棍子或竹板子打。

Chinese New Year for Kids ‘Chinese New Year for Kids’ is a full color paperback book with beautiful Chinese illustrations (插图). This is a hands-on workbook for parents and teachers, written for children from ages 3 to 12 years old, for use in the classroom or at home. Music, physical movement, art, and food all add to the atmosphere of taking an imaginary trip to China during the Chinese New Year.
One couldn’t select a more delightful and exciting premise (前提) for a children’s book than the tale of a young boy lying awake on Christmas Eve only to have Santa Claus sweep by and take him on a trip with other children to the North Pole. And one couldn’t ask for a more talented artist and writer to tell the story than Chris Van Allsburg.
Perhaps you’d like to know a secret, one of the happiest ones of all. You’ll discover it all on your own, maybe when you least expect. If you’ve not yet discovered the secret of saying thanks, it’s waiting for you. The secret can be found in the sunrise that offers promises for the day ahead, or in the gentle shade of a tree sheltering you from the hot rays of the sun.
When Buck, Billy and their little sister Lily spy the biggest pumpkin they’ve ever seen, they can’t resist (抵制). Buck and Billy try to roll the pumpkin down the hill to show everyone, but it’s too big! Before they know it, it’s rolling out of control down the hillside. It knocks over Grandpa Baxter and makes him think of pumpkin soup. And when Poppa Baxter finally stops, all he can think of is pumpkin bread.
