Reading comprehensionA. Choose the best answer/info.htmABOUT INTERNET HOAXES MORE INFO CONTACT USThe Internet is full of false information. It is important for us all to avoid being fooled by such information. Here are three examples of Internet hoaxes.On his website, a man by the name of Tony has asked for gifts of money to save the life of a pretty little rabbit named Toby that he rescued from under his house. A cat must have attacked the rabbit, the man claimed, so he took it in. He gave Toby loving care and nursed him back to health. There is a very cruel point, however. If the greedy man doesn't receive enough money, he will eat poor little Toby. (Don't worry, though. Remember, it's just a hoax!)While the streets of New Orleans, the USA, were still flooded after a terrible hurricane(飓风), a frightening e-mail was sent around the Internet. It included a photograph of a large crocodile over five meters long. According to the message, it had been swimming around the flooded city eating people. It was later discovered that the photographs of the crocodile were of one that was caught in the Congo(刚果) years before.The following e-Mail hoax takes in many people. It claims that a large British company will pay you to send their e-mail to as many people as possible. For every person that you send the e-mail to, it promises you will receive $5.00; for every person that you send it to that sends it to someone else, you'll get $3.00; and for every third person that receives it, you will be paid $1.00. To make it even more believable, the sender says that at first he thought it was a hoax, but the company soon sent him $800.00.69. The underlined word "hoaxes" means ______A) games B) websites C) lies D) stories70. Toby is the name of a ______A) man B) rabbit C) website D) cat71. The crocodile in the photograph actually lived in______A) New Orleans B) the USA C) Britain D) the Congo72. Some people believe that they can ______ if they send e-mails.A) become famous B) find friends C) make money D) keep promises73. Which of the following is TRUE according to the passage? ______A) The city of New Orleans was flooded because of the terrible hurricane.B) lf the man doesn't receive enough money, he will eat poor little Toby.C) The crocodile swam around the flooded city and ate several people.D) Someone received $800.00 from the company because of the e-mail.74. The main idea of the passage is to______A) teach how to create a professional website with attractive storiesB) show that anyone can create good Internet hoaxes with some factsC) explain that, even though they seem false, Internet hoaxes might be trueD) tell people to be careful of Internet hoaxes by giving some examplesB. Choose the words or expressions and complete the passageAlthough the first airplane did not fly until 1903, flying soon became the fastest method of transport. Today it is 75 people's favourite way of traveling long distances because it has a lot of advantages. The first airplanes were not big or powerful enough to carry more than a pilot, but during the First World War (1914-1918) larger aircraft with up to four engines were 76 to carry bombs(炸弹). After the war some of these were changed to carry a few passenger services. In 1919 the first regular passenger services were started between several cities in Europe.Air transport was even then too 77 for most cargoes(货物), but mail began to be carried by air at an early stage. This was partly because letters are small and light, and partly because businessmen, especially, were prepared to pay more for their mail to be delivered by the fastest method. 78 , in the United States, where letters could take over a week to cross the country by train, airmail services were the first regular transport flights.The early passenger aircraft could carry only about 12 passengers, and only enough 79 for short journeys. For long distances, such as from Europe to the United states, filled with very light gas and able to float through the air, began to be used in the 1930s.By the end of the Second World War in 1945, much larger airplanes had been made. At the same time, military(军事的) airfields had been built all over the world, and long-distance routes had been set up. After the war, the introduction of the jet engine, which 80 much greater power, allowed even bigger and faster aircraft to be built. Today's wide-bodied airplanes can carry as many as 800 passengers.Modern air transport passenger services are quite convenient. Air transport has allowed more people to travel abroad than ever before.75. A) quietly B) easily C) directly D) recently76. A) recognized B) considered C) developed D) described77. A) expensive B) ordinary C) traditional D) private78. A) After all B) For example C) In addition D) On average.79. A) time B) money C) food D) fuel80. A) produces B) attracts C) reuses D) spreadsC. Read the passage and fill in the blanks with proper wordsBeatlemania is a very strong feeling for the group, the Beatles. The Beatles were four young musicians from Liverpool, England. Their n 81 were John Lennon, Paul McCartney, George Harrison and Ringo Starr. These four men n 82 took music lessons. They taught themselves to play music.In 1957, John c 83 a group called the Quarrymen. At that time, he was only 16 years old. Then he met Paul. They began to write songs and sing together. Soon, George joined them. The group played in England, and then in Germany. In 1962, Ringo joined them. Then John, Paul, George and Ringo were the Beatles.The Beatles made their f 84 hit song in 1962. The song was "Love Me Do." In 1963, their song "Please Please Me" was a bigger hit. In all, they had twenty-nine hit songs. By 1963. the Beatles were very p 85 in England, and Beatlemania started. They had many fans. At concerts, their fans screamed very very loudly. The Beatles could not hear themselves sing.The next year, the Beatles went to the United States. The Americans loved them, too. People everywhere c 86 their clothes and their hair. This rock-and roll group was welcomed by people all over the world.The Beatles broke up in 1970. They wanted to play new music. All of the Beatles did interesting, new things. John wrote music with his wife. Paul started a new group with his wife. George and Ringo made their own r 87 and gave concerts. Sadly, John was shot dead in New York in 1980. He was forty years old. George became sick and died in 2001.We still hear Beatles songs on the radio today. Their music and songs will live in our hearts for ever.D. Answer the questionsOnce there Was a little girl named Mary Lennox and her two little friends, Dickon and Colin. Both of Mary's parents died when she was a little baby. She was sent to her uncle, Mr. Archilbald Craven, who had a son named Colin.Mary was once a selfish(自私的) girl. She cared for nobody else except herself and she was always alone. She started to know the word "friend" after she met Dickon, the gardener's son. The little boy was very kind to Mary. They went to the Secret Garden every day, planting and playing. Mary never expected that making the garden beautiful would bring such a wonderful feeling to her. She was so happy to be with Dickon that she almost forgot all the sad things around her. She came out of her small lonely world.After she met Colin, Mary finally found the very person to take care of. Colin, the sick boy whocouldn't even walk, had been in bed for about ten years. Before he met Mary, he was taken care of by the servants, but no one really cared how he was. He couldn't find any reason to live. So he cried and cried, thinking about death. But Mary came. Colin was completely attracted to Mary and to all those fresh thoughts and stories which came out of her mouth. Of course, the most exciting of all was the Secret Garden.The feeling of having someone share your secret is wonderful, especially for the children. Colin used to be too weak to change his life, but now he had Mary, Dickon and the Secret Garden. All these gave him courage. Finally, with the help of his two little friends, he managed to stand up for the first time.88. Did Mary care for anybody else except herself at first?89. Why was Mary sent to her uncle's ?90. What did Mary and Dickon do in the Secret Garden?in it.91. How was Colin before he met Mary?92. Where did Colin's courage come from?93. Who do you think changed the most in the story?

纳木错湖面海拔4718米,东西长约70千米,南北宽约30千米,面积达1980平方千米,它是世界上海拔最高、面积最大的咸水湖。
②自本世纪以来,居住在纳木错湖畔的牧民们发现,纳木错的湖水在一点一点向他们的居住地靠近,导致很多牧民的家园被湖水淹没,他们只好举家搬迁到更高的地方居住。
③中科院纳木错综合观测站的工作人员发现,在1970~2009年的近40年时间里,纳木错的水位上涨了7米,湖面海拔从4718米变成现在的4725米,整个湖水增加近140亿立方米。
纳木错湖水为何会突然上涨?那些增加的水是从哪里来的?④人们首先想到就是“全球变暖”。
气候变暖使得气温升高,导致湖水蒸发量加大,最终造成湖水水位下降。
按照这个推理,纳木错湖水的水位应该是下降的,为什么实际情况却是完全相反的呢?⑤研究人员认为,如果是在内陆,上面提到的这种思路....也许完全正确;但这里是高原,纳木错是世界上海拔最高的咸水湖,影响湖水水位上升的因素包含全球气候变暖,但并不能单纯地去考虑大气这一个因素,而是要综合考虑影响水循环的各个可能因素。
⑥在西藏地区,全球变暖导致的最为显著的变化就是冰川融化。
在纳木错周围,有很多白皑皑的雪山,这些雪山实际上就是冰川。
比较著名的冰川有西布冰川、扎当冰川、拉弄冰川、爬努冰川等。
这些冰川每年都在融化,向下游补给水源,又在每年冬天的时候通过降雪补充冰川的消融量,最终形成一种动态平衡。
然而,随着全球气候变暖的加剧,这种动态平衡被打破,冰川融化速度加快,而冰川通过降雪所获得的补给量远远少于融化量。
这样一来,冰川不断退缩,冰川融化的水大部分注入纳木错湖中,最终造成湖水水位上涨。
⑦另外,纳木错周边地区的海拔高度基本都在4000米以上,属于高寒地区,地表在常年低温的作用下形成一层厚厚的冻土。
这些冻土在低温状态下,长期以冰的形态存在。
气温升高后,特别是冬季气温加快上升,冻土层厚度减小,甚至很多多年累积下来的冻土和冰层都开始融化。
这些融化的水也会注入地势较低的纳木错湖中,造成湖水水位上涨。
⑧既然全球气候变暖会导致水体蒸发量加大,那么纳木错的湖水蒸发是否受此影响呢?研究表明,蒸发是一个受多种因素影响的气象要素,伴随气温的升高,水体的蒸发量不一定随之增加,它还与云量、日照、辐射等因素密切相关。
根据科学院的研究分析,在水位上涨的那几年,纳木错地区的云量,特别是低云量增加了,但纳木错地区的蒸发量相比之前反而减少了。
这意味着,蒸发量的减少也是造成纳木错水位上升的一个原因,但与冰川和冻土对湖水水位的影响相比,这一因素要弱得多。
⑨因此,关注气候、关注我们居住的地球,意义非常重大。

18、第⑤段加点部分“这种思路”指的是,段中的“但是”隐含的是第二种思路,推测作者的第二种思路是(4分)(二)阅读下文,完成19-23题。
(20分)儿女总是父母的作品王安忆①天下的母亲都爱操心,我妈妈是天下母亲中最爱操心的母亲。
在她眼里,我们儿女全是还没孵出蛋壳的鸡,她必须永远孵着我们。
②妈妈时常辅导我们功课,尤其是算术,她不希望我们去搞文科,而要我们搞理工科。
她明白理工科的基础,在小学里便是算术了。
有一次,临近大考,她辅导我“换算”。
她一定要问我:“一丈等于多少米?”我说:“老师只要我们知道一米等于多少市尺就行了。
”可是,妈妈说:“万一有一道题目是一丈等于多少米,你怎么办呢?”她的逻辑是对的,我想不出任何道理来反驳,于是便只能无奈地跳脚了。
③其实,她辅导我语文恐怕更合适一些,可她并不辅导,只管制我读书。
第一次看《红楼梦》是在我小学四年级,妈妈把那些不适于我读的地方全部用胶布贴了起来,反弄得我好奇得难熬,千方百计想要知道那胶布后面写的是什么。
④后来,我和姐姐先后去插队,终于离开了家,可我们却像风筝,飞得再高,线还牢牢地牵在妈妈手里,她时刻注意我们的动向。
后来,我到了一个地区级文工团拉大提琴,妈妈凡是路过那里,总要下车住几天。
有一次,我告诉她,我们去了一个水利工地演出,那里有一座大理山,有许多大理石等等。
妈妈便说:“这是个散文的意念,你可以写一个散文。
”这时候,我已年过二十,大局已定,身无所长,半路出家的大提琴终不成器。
妈妈在我们身上寄托的理工之梦早已破灭,又见我一人在外,饱食终日,无所事事,反倒生出许多无事烦恼,便这么劝我了。
之后,闲来无事,写成一篇散文,不料想这成了我第一篇印成铅字的作品,给了我一个当作家的妄想。
⑤于是,我便开始舞文弄墨,每一篇东西必须妈妈过目,然后根据她的意见修正,才能寄往各编辑部,再次聆听编辑的意见,再次修正。
她比编辑严格得多,意见提得极其具体、细微。
我常有不同意之处,可是总不如她合乎逻辑,只好心服口服地按照她做了。
⑥然后,我去了北京讲习所,风筝的线仍然牵在她手里,每一篇东西总是先寄给她看。
不过,与先前不同的是,妈妈同意让我听了编辑部的意见以后,再考虑她的意见。
这时,我如同闸门打开,写得飞快,一篇连一篇,她实在有些应接不 xiá了。
终于有一天,她紧接一封谈意见的信后又来了一封信,表示撤销前封信,随我去了。
风筝断了线,没头没脑地飞了起来,抑或能飞上天,抑或会一头栽了下来,不过,风筝自己也无须有什么怨言了。
这后一封信是在我爸爸的劝说下写的,爸爸劝妈妈不要管我,随我自己写去。
这是爸爸对我们的一贯政策,他对我们所有的担心只有一点,就是过马路。
出门必须说一句:“过马路小心!”其他都不管了。
似乎普天下只有过马路这一危机,只要安全地穿过马路,人平安无事地在,做什么都行,什么希望都有。
⑦长大以后,说话行事,人家夸,总夸“你爸爸妈妈教养得好。
”有所不满,总说:“给你爸爸妈妈宠坏了。
”似乎,对于我们,自己是一点功绩也没有的。
或许也对。
⑧小时候,我喜欢画画,画的画也颇说得过去,可无奈大人要我学外语,请来老师,一周三次上英语课。
只能应付。
到了末了,连敷衍也敷衍不下去了,只得停了课。
如今,我每周两次,心甘情愿地挤半小时汽车,前往文化宫学习英语,苦不堪言地与衰退的记忆力搏斗着,不由想,假如当年,父母对我拳棒相加,也许这会儿早能看懂原版著作了。
再一想,假如当年,大人听顺我的志趣,或许现在也能画几笔了。
倒是这样似管非管,似不管也非不管,弄出了一个做小说的梦。
想来想去,儿女总是父母的作品。
他们管也罢,不管也罢,都是他们的作品。
风筝或许是永远挣不断线的。
