《中华人民共和国义务教育法》当前版本是2015年4月24日第十二届全国人民代表大会常务委员会第十四次会议修正的。
阅读下面的文章，完成下列小题。 游鉴湖 许钦文 ①艺术家依照自然景物作画，叫做写生。所谓风景如画，是说美好的风景。拿画来形容风景的好，因为有些画是经过艺术家美化了的风景的写照。“风景如画”的意义，我日前在绍兴才深刻地体会到。 ②我坐着踏桨船，到小云栖等地方去看看，觉得路上风景实在可观。偏门外，虽然由石条叠成圆洞的高高的跨湖桥已于抗日战争时期毁掉，可是快阁所在，是爱国大诗人陆游写过“风吹麦饭满村香”的地方，大片银波粼粼的水，远处衬着青青的山，湖光山色依然。在那青山绿水之间，金黄黄的早稻穗和碧油油的晚稻苗一方一方地间隔在田间；还有杨柳、柏树排列在河岸和田塍上。且不说经过鱼荡的箔时，那竹笆刮着船底的清脆悦耳声，在菱荡旁垂钓鲈渔翁的悠然的姿态。往常我也只有在画面上见到过。绍兴一大部分是平地，所以河流通常总是静止的样子。水面貌如镜，这就成了“镜湖”，也称“鉴湖”。一个魁星阁，一座三眼桥，几株柏树，一丛松树，砖墙的楼房，茅草的平屋，摇着橹的出畈船和供行人休息的路亭等，分开来个别观看，没有什么特别，可是配置在稽山镜水之间，这就千变万化，形成了许多醒目的景象。有名的峨眉山，所谓风景奇特，五步一小变，十步一大变的，我欣赏过一个星期。虽然多变化，可是气势太急促，岩石峰峦，近近地迫在眼前，往往看得透不过气来的样子。会稽山脉在鉴湖水上观望，似乎淡淡的几笔，远远的，只是衬托的背景。可是我能想见：那里禹陵、兰亭等古迹的所在，崇山峻岭之间长着茂林修竹，雄伟、庄严，也是秀丽的。坐在船上摇动着，也可以说是“五步一小变，十步一大变”的，却处处使人眼开眉展、爽神悦目。我坐在踏桨船上，一桨一桨地踏过去，眼前景物渐渐地转变，一幅一幅的图画，好像是在看优美的风景片子的电影，真是百看不厌的。杜甫有诗说，“越女天下白，鉴湖五月凉。”这凉是清凉爽快，无论何时，看着鉴湖的风景，总是觉得爽愉的呀! ③绍兴是我的故乡，偏门外一带是我旧游之地，以前我可没有这样感兴趣过。固然，由于年龄、世故等关系，有些事情一时体会不到真情，像我早在中等学校里唱过的“鸟鸣山更幽”和“夜归鹿门”等歌词，一直要到我年已半百在福建永安的山上时才忽然体会到，却也只是一会儿就过去了的。如今鉴湖风景给我优美的印象是使我念念不忘的了。“静观万物皆自得”，原来在旧社会里，我迫于生计，一直匆匆忙忙，没有好好地安静过心镜。不久以前我到北京去开会，在火车开出城站时，我忽然想到，以前我屡次北上，总是为着生计，这次才主要的是为着事业。 ④新社会给我们的幸福，并不限于物质条件，更加是精神上的可以愉快，得到安慰! ⑤1956年秋于西子湖畔的桃花江边。
创设良好课堂气氛的条件是______。
Walt Disney is credited for creating such wonderful things as Donald Duck and Mickey Mouse. However, he cannot take the credit for creating other well-loved characters, such as Cinderella and Snow White.
They
are almost automatically associated with Disney because Disney turned old fables(寓言)into cartoon movies.
The original Cinderella varies very much from the Disney version we know today. It started off with the girl mourning her mother's death and going to her tomb three times a day. In addition, there were only birds that helped Cinderella; there was no such thing as a fairy godmother or helpful mice, nor was there mention of a horse and carriage.
The stepsisters were cruel; they always threw Cinderella's food into the ashes of the fire and made her sleep on the ashes on the floor, hence(因此)her name.
In the original story, the king's ball actually lasted for three days. With the help of the birds, the girl, beautifully dressed, danced with the prince on all three nights and the prince fell in love with her. However, she broke away from him to rush back home each night. On the last night, the prince placed something sticky on the stairs; as Cinderella made her escape, a shoe got stuck on it.
Here now is where the story becomes unpleasant: when the prince went to the house looking for the girl whose foot fit the shoe, the wicked(邪恶的)stepmother told one of her two daughters to cut off her big toe to fit into the shoe. The daughter did as told. So the prince took her away to be his bride. But when they passed the tomb of Cinderella's mother, the birds called out to the prince,
"Turn and peep, there's blood in the shoe;
the shoe is too small, the true bride waits for you.
Realizing he had been tricked, the prince returned the daughter to her mother. The other then had to cut off part of her heel in order to fit into the shoe, with the same result. Only Cinderella's foot fit perfectly and so the prince chose to marry her. The story ends with the wedding day: as Cinderella's two stepsisters followed her, pretending to be devoted to her so that they could enjoy the king's riches, two birds flew by and plucked(啄)out their eyes. Because of their wickedness and falsehood, they had to spend the rest of their days blind.
The original Cinderella is so different from the Disney version. Thank goodness Disney made such changes; it indeed was a wise move.
