     Galaxy saw a man and a woman who communicated with the sign language at the train station when

she was on the way home one evening. She noticed that the woman asked the man for the direction. He

told her that he did not know. Galaxy decided to help them. She had learned the sign language when she

served as a volunteer in the deaf and mute (聋哑) school. Then she showed the woman the direction and

left her email address to them in case they needed her help later.

    She received an email from that man the next day. Kazrim was his name. Galaxy replied his mail

sincerely. They both started chatting online soon after and began seeing each other. Although they only

communicated with the sign language, it never bothered her.

    Galaxy was fond of him gradually. Obviously, Kazrim was the same too. He presented Galaxy with a

bunch of sunflowers and asked her sincerely, "Are you willing to be my girlfriend?" Galaxy was pleasantly

surprised. She requested him to give her some time to persuade her parents.

    As she had expected, her parents were very angry after they had learned of their love story. Galaxy

explained, "Kazrim is an excellent and a very optimistic person. He has a very positive attitude towards

life and work. He cares for others always. He is 100% better than the normal. Moreover, the mute is

still a human. He should possess a perfect and wonderful love."

    Her parents asked to see him, then. The very worried Galaxy took Kazrim home a few days later.

When they were on the train, Kazrim told her, ''I'm going to tell your parents I'll be looking after you well with all my life!" Galaxy was deeply moved.

    As soon as they had entered the house, Galaxy introduced him to her parents. She said, ''This is Kazrim." Just right after her speech, an unbelievable thing happened. Kazrim threw the gift away and held her

in his arms tightly.

    He said, "YOU CAN TALK?" It was the same question that Galaxy wanted to ask, too.

    The four people were shocked all of a sudden. As a matter of fact, Kazrim always believed that Galaxy was a mute and he still fell in love with her deeply.

1. How did Galaxy and Kazrim get to know each other?

A. They met each other by chance.    

B. They were introduced to each other.

C. They once studied at the same university.  

D. They both served in a special needs school.

2. How did Galaxy probably communicate with Kazrim before she took him home?

A. Writing words on paper.    

B. Using the sign language. 

C. Judging from his expression.  

D. Speaking her native language.

3 What did Galaxy expect her parents to do?

A. To have a talk with Kazrim.    

B. To prepare for her marriage.

C. To treat Kazrim as a normal man.

D. To accept Kazrim as her boyfriend.

4 What can we learn about the two young people from the passage? 

A. They fell in love at the first sight.    

B. They cheated each other to win love. 

C. They mistook each other for being mutes.

D. They ignored the anger of Galaxy's parents.

青藏铁路堪称“世界冻土工程博物馆”

随着冻土路基、冻土区桥梁、涵洞、隧道、房建、管线等工程的顺利施工,世界上海拔最高、穿越高原多年冻土最长的青藏铁路,如今堪称“世界冻土工程博物馆”。专家称,青藏铁路穿越世界上最复杂的冻土区,不少冻土工程措施都是国内外首创,可谓集冻土工程之大全。

于7月1日试通车的青藏铁路格尔木至拉萨段,是目前全球穿越永久性冻土地带最长的高原铁路,这条铁路处于多年冻土区的线路就长达550公里。而冻土对温度极为敏感,随着温度的变化,它会“发胖”或“变瘦”。

据了解,冻土在寒季就像冰一样冻结,随着温度的降低体积会发生膨胀,建在上面的路基和钢轨就会被“发胖”的冻土顶得凸起;到了夏季,融化的冻土体积缩小,路基和钢轨又会随之凹下去。冻土的冻结和融化反复交替地出现,路基就会翻浆、冒泥,钢轨会出现波浪形高低起伏,对铁路运营安全造成威胁。

青藏铁路建设总指挥部专家组组长、冻土科学专家张鲁新说,冻土虽然在加拿大、俄罗斯等国家也存在,但他们是属高纬度冻土,比较稳定。青藏铁路纬度低,海拔高,日照强烈,而太阳辐射对冻土有着非同寻常的影响。加上青藏高原年轻,构造运动频繁,并且这里的多年冻土具有地温高、厚度薄、热融发育等特点,其复杂性和独特性举世无双。

据了解,青藏铁路有111公里线路铺有一种特殊的路基,即在土路堤底部填筑一定厚度片石,上面再铺筑土层的路基。这种多孔隙的“片石层通风路基”为国内首创。它是效果较佳的保护冻土措施,好似散热排风扇,冬季从路堤及地基中排除热量,夏季较少吸收热量,起到冷却作用,能降低地基土温度0.5摄氏度以上。

全长11.7公里的青藏铁路清水河特大桥横架在可可西里冻土区,它是一种“以桥代路”的保护冻土措施,铁轨飞架而过可以不惊扰冻土。青藏铁路“以桥代路”桥梁达156.7公里,占多年冻土地段的四分之一。张鲁新说,如此大规模采取“以桥代路”措施,在世界上也是首次。

青藏铁路有的冻土路基两旁插有一排排直径约15厘米、高约2米的铁棒,这就是热棒。它是一种高效热导装置,具有独特的单向传热性能:热量只能从地面下端向地面上端传输,反向不能传热,可以说是一种不需动力的天然制冷机,专家称之为冻土病害的“青霉素”。大规模使用热棒可以保持多年冻土处于良好冻结状态。

青藏铁路建设总指挥部指挥长黄弟福说,青藏铁路建设中创造性地采取了解决冻土施工难题的相应对策:对于不良冻土现象发育地段,线路尽量绕避;对于高温极不稳定冻土区的高含冰量地质,采取“以桥代路”的办法;在施工中采用热棒、片石通风路基、片石通风护道、通风管路基、铺设保温板、遮阳篷结构等多项设施,提高冻土路基的稳定性,堪称集世界冻土工程措施于一身。因此,运行在青藏铁路上的列车时速将达120公里。

小题1:下列关于青藏铁路堪称“世界冻土工程博物馆”的理解正确的一项是         (   )

A.青藏铁路是世界上海拔最高、穿越高原多年冻土最长的铁路。

B.青藏铁路冻土工程多而复杂,施工中集世界冻土工程措施于一身。

C.青藏高原冻土具有地温高、厚度薄、热融发育等特点,其复杂性和独特性举世无双。

D.青藏铁路在冻土上建起的路基、桥梁、涵洞、隧道、房建、管线等工程项目最多。小题2:根据原文提供的信息,下列表述不符合原文意思的一项是               (   )

A.气温升高,冻土热涨“发胖”;气温降低,冻土冷缩“变瘦”,威胁铁路营运安全。

B.青藏铁路,是目前全球穿越永久性冻土地带最长的高原铁路。

C.大规模采取“以桥代路”措施,保护冻土,我国首创。

D.热棒具有独特的单向传热性能,利用它可以保持多年冻土处于良好冻结状态。小题3:根据原文提供的信息,下列推断正确的一项是                   (     )

A.青藏铁路建设虽创造性地采取了解决冻土施工难题的相应对策,但也不可能一劳永逸。

B.采取多种措施,提高冻土路基的稳定性,主要是为了提高列车时速。

C.青藏铁路建设冻土问题的彻底解决标志着我国铁路建设技术已居世界领先地位。

D.虽然冻土对温度极为敏感,但因环境恶化导致的全球变暖不会影响冻土的变化。
