根据短文理解,选择正确答案。

    Anny was a five-year-old girl. One day when she and her mother were in a department store(百货商店), Anny saw a plastic pearl necklace (珍珠项链). What a beautiful necklace! She wanted it very much, so she begged(乞求)her mother to buy it for her. The mother said, “Well, I can buy you the necklace, but when we get home, we should discuss what you can do to pay for it. Can we do that?” Anny agreed with much happiness, and she got the necklace.

    How much Anny loved the necklace! She wore it everywhere and every minute. Anny also did part - time jobs to make pocket money. She worked very hard. Soon she succeeded in paying off the price for the necklace.

    Anny's daddy knew how she tried her best to get the necklace. He also knew how much Anny cared about it. One night, he asked Anny if she loved him. “Sure, Daddy.” the little girl said. “Then how about giving me your necklace?” “Oh, no, Daddy! Not my necklace!” Anny cried. “Oh, dear, it's fine.” her father gave her a kiss.

    Several days later, Anny went to her daddy, with her lips(嘴唇) trembling(颤抖). “Here, Daddy. I love you.” She held out her hand. Inside it was the plastic pearl necklace that she loved so much.

    When he saw this, Anny's father smiled with surprise. He then pulled a cute box out of his pocket. Inside the box was a real and colourful pearl necklace, which was waiting for Anny for so long.

阅读下文,完成后面小题。

       ①满天都是星光,火把也亮起来了。从山脚向上望,只见火把排成许多“之”字形,一直连到天上,跟星光接起来,分不出是火把还是星星。这真是我生平没见过的奇观。

       ②大家都知道这座山是怎样地陡了,不由浑身紧张,前后呼喊起来,都想努一把力,好快些翻过山去。

       ③“不要掉队呀!”

       ④“不要落后做乌龟呀!”

       ⑤“我们顶着天啦!”

       ⑥大家听了,哈哈地笑起来。

       ⑦在“之”字拐的路上一步一步地上去。向上看,火把在头顶上一点点排到天空;向下看,简直是绝壁,火把照着人的脸,就在脚底下。

       ⑧走了半天,忽然前面又走不动了。传来的话说,前面又有一段路在峭壁上,马爬不上去。又等了一个多小时,传下命令来说,就在这里睡,明天一早登山。

       ⑨就在这里睡觉?怎么行呢?下去到竹林里睡是不可能的。但就在路上睡么?路只有一尺来宽,半夜里一个翻身不就骨碌下去了么?而且路上的石头又非常不平,睡一晚准会疼死人。

       ⑩但这是没有办法的,只得裹一条毯子,横着心躺下去。因为实在太疲倦,一会儿就hān然入梦了。

       ⑪半夜里,忽然醒来,才觉得寒气逼人,刺入肌骨,浑身打着颤。把毯子卷得更紧些把身子蜷起来,还是睡不着。天上闪烁的星星好像黑色幕上缀着的宝石,它跟我们这样地接近哪!黑的山峰像巨人一样矗立在面前。四围的山把这山谷包围得像一口井。上边和下边有几堆火没有熄;冻醒了的同志们围着火堆小声地谈着话。除此以外,就是寂静。耳朵里有不可捉摸的声响,极远的又是极近的,极洪大的又是极细切的,像春蚕在咀嚼桑叶,像野马在平原上奔驰,像山泉在呜咽,像波涛在澎湃。不知什么时候又睡着了。
