    Once there was a merchant who had fine silks and rug(s a city on the other side of the desert (毛毯) to sell. He wished to send his goods to Abdul the merchant owned a large caravan(商队)of camels, and he employed many men. For many days, Abdul and his men had been preparing for the journey, because of the boundless desert with hot sand and the grass out of sight for miles. It required many camels to carry the merchant's goods, tents, bottles of water, firewood, bags of rice and some tools.

    At last the caravan was ready for the journey. The sun shone steadily, making the sand so hot that no one could walk upon it in the daytime. So Abdul and his men traveled all that night. One man was the pilot. He rode ahead because he knew the stars, and he could guide the caravan by them.

    They traveled night after night, resting during the heat of the day. Unfortunately, when the caravan started another evening, the pilot led the way as usual, but after a while, weary with many nights of watching, he fell asleep.

    All night long the caravan traveled. At daybreak the pilot awoke and looked at the last star fading in the morning light. "Halt(停下)!" he called." The camels must have turned while I slept. We are at the place from which we started yesterday." Even worse, another man shouted, "The man with the camel carrying the rest water and firewood, who is walking at the end of our group, is gone!"

    There was no water to drink. There was no firewood to cook the food. The men lay down with despair, "We are lost!"

阅读下面的材料,完成下列小题。

材料一:①中央电视台文化情感类节目《朗读者》播出后好评不断,如一股清风唤醒了大众对朗读的情感。《朗读者》节目每一期都有一个主题词,如节目第一期的主题词是“遇见”,其中一段开场白是这样的:“其实,世间一切,都是遇见。就像冷遇见暖,就有了雨;春遇见冬,有了岁月;天遇见地,有了永恒;而人遇见人,就有了生命。”

材料二:《朗读者》节目将文字、声音和情感巧妙地联系在一起,让观众感受到文字、声音以及情感之美。有研究表明,大声朗读需要集中精力,大脑处于“排空”状态,有利于记忆;大声朗读会使脑神经处于于极度兴奋状态,有利于思考;②大声朗读还有利于再现文章的“诗性美”。

材料三:当我们被另一档热播的文化情感类节目《见字如面》中的信件感动得眼角湿润时,有没有想过,③在信息化时代,习惯了在键盘上“敲字如飞”,还能不能写出几个像样的字代表我们的“面”呢?现在,我们也许已懒得动笔写字了;也许提起笔来,不是忘了字就是写了错别字;也许即便写出来,字体也实在有碍观瞻。

材料四:著名教育家于漪老师说过:“学语文就是学写字。”我们总结说“字如其人”“见字如面”,写得一手好字会给你带来不一样的机遇。④练字如修面,可以增强一个人的内在气质。
