Reading comprehensionA. Choose the best answerOnce upon a time if we wanted to make a phone call or wait for someone tocontact us, we had to sit at home or at our desks. There were public phones in the streetof course, but it could be hard to find one that was working and there were often longqueues to use them. And of course you had to bring a lot of coins to pay for the calls.So people didn't phone their friends as often. Mobile phones, these small pieces ofelectronic equipment which allow us to talk with friends and family while we are onthe move, have greatly changed the way we live. Before the age of the mobile phone,our loved ones would sit around worried sick if we were late coming home. There wereno quick calls to tell mum that there would be additional guests coming for dinner. Wewould have to depend on notes left on fridges or desks to communicate messages.But mobile phones have also had a negative effect and what people don't seem to realize is that we'velost something very valuable: our privacy. Now our friends and family can contact us wherever andwhenever they want to. We can never get away from them. The way people communicate with each otheris totally different now. It's difficult to have a conversation face-to-face with a friend without beingdisturbed every couple of minutes by the ring of their phones, ,most people don't see anything wrong inhaving a long conversation on their mobile phone while forgetting all about the person sitting opposite. Itseems the art of real conversation may be dying.Of course, people could leave their mobile phones at home or even switch them off but no one everdoes that. Why not? Because the worrying thing is we can't live without our phones. We've becomecommunication addicts, unable to spend even a few minutes out of contact, in case we miss something 'important'.69. What does the underlined sentence tell us?A) No all-day public phone service was provided in the street.B) Public phones were in poor condition and not always available.C) Public phones were everywhere but they were always in use.D) You could always see people repairing the public phones.70. What's the writer's point about using telephones before the invention of mobile phones?A) Using a telephone was expensive. B) Phone calls were much shorter.C) People made fewer phone calls. D) People relied on notes a lot.71. What does the writer think about life before mobile phones?A) Life was less convenient. B) People were more punctual.C) Things were more relaxed. D) Everyone managed very well.72. What's the writer's main argument against mobile phones?A) They have damaged relationships. B) We give out too much information.C) They are harmful to our body and mind. D) It's impossible to escape from them.73. Which word best describes how the writer feels about the use of mobile phones.'?A) Disappointed. B) Satisfied. C) Worried. D) Surprised.74. What's the writer's main purpose in writing this article?A) To inform people about means of communication in the past.B) To show disadvantages of the way people communicate today.C) To advise readers to stop using the mobile phone.D) To compare different types of phone conversation.B. Choose the words or expressions and complete the passageThe International Climate Champions (ICC) project began in 2007. It gives young people of schoolage a chance to speak publicly on climate change and to call on people to take action to reduce its 75 .Each country involved selects three teenagers to be Climate Champions, who take part in local andinternational activities.Climate Champion Irene Sanna lived on the Italian island of Sardinia. Irene is interested in solarenergy, and 76 believes that Sardinia should use the waves around its coast to produce electricity.'We must make our plans to save our coast, which still has no pollution. We must protect the animals, birdsand fish in danger from global warming. And we must recycle.'Chinese student Ding Yinghan is the Beijing Climate Champion. Ding feels it is not 77 tosaythat just one country - his own - is causing climate change. He says the air pollution that leads to globalwarming comes from many parts of the world, including poorer countries that are now growing morequickly. He believes the only way to 78 the situation getting even worse is for rich and poor countriesto work together.Sophia Angelis, a junior student in California, is a US Champion. She's against young people'sgeneration lack of interest in politics and feels they need to discuss the problems that really matter to theirgeneration. Sophia strongly believes that climate change is an important issue for her generation. For her,79 in the way teenagers behave are an important way of influencing choices made by parents.In 2008, the Climate Champion attended the International Conference of Environment Ministers in theJapanese city of Kobe. 80 ,30 countries are involved in the ICC, and more countries are expected tojoin soon.75.

Read the passage and fill in the blanks with proper wordsSomeone sent me a group e-mail the other day. One of those that end with: send this to 10 friends ... Iliked the story and it really got me thinking.Here's the story from the e-mail:Recently I overheard a father and a daughter in their last moments together at the a 81 . They hadannounced the departure.Standing near the security gate, they hugged and the father said, 'I love you, and I wish you enough.' They kissed and the daughter left. The father walked over to the window where I was seated. I tried toleave him some privacy, but I could not keep m 82 from asking:'When you were saying good-bye, I heard you say, 'I wish you enough.' May I ask what that means?'He began to smile. 'That's a wish that is p 83 on from generation to generation. My parents usedto say it to everyone.'He paused a moment and looked up as if trying to remember it in d 84, and he smiled even more. 'When we said, 'I wish you enough,' we were wanting the other person to have a life filled with justenough good things to carry them on.'T 85 , slowly turning toward me, he shared the following as if he were reciting it from memory.I wish you enough sun to keep your attitude b 86 no matter how gray the day may appear.I wish you enough rain to appreciate the sun even more.I wish you enough happiness to keep your spirit alive and everlasting.I wish you enough pain so that even the s 87 of joys in life may appear bigger.I wish you enough gain to satisfy your wanting.I wish you enough loss to appreciate all that you possess.I wish you enough hellos to get you through the final good-bye.D. Read what Claire did and answer the questionsMy stay in the rainforestLast year, I left my job and went to Borneo to work without pay in the rainforest. So many people have said to me, 'I would love to do something like that,' and I say, 'If you want to, just do it.' They always reply, 'l can't.' But, ifyou really want to do it, there are ways to make it happen.After three day's training, I started work on an environmental project with a group of young people. The accommodation was very basic and we had to build our own place to sleep. This consisted of a simple bed, a cloth roof and a net to keep insects (昆虫) out.It was never dangerous there, but it was very challenging (挑战的). There were things that we didn't think we would manage to do, but we did. I had some of my worst moments there, but alsosome of my best - it made me feel alive. I didn't miss my home comforts as much as I'd thought I might. We had food, water, somewhere to stay, about three sets of clothes and really good conversation. We were in the most beautiful place and we had things to keep us busy. We didn't need any more.One of the teenagers said, 'Before we came here, it was really important to me what clothes I wore and who my friends were. I was always thinking about shoes, but really none of that matters. Here, people accept me for who I am, what I believe and think, not for what kind of clothes I've got.' When she said that, it summed it up for me.88. Did Claire get any money from the work in Borneo?89. What did Claire do before she started work on an environmental project?90. How was Claire's 'bedroom' in the rainforest?91. What did the teenager care about before she came to Borneo?92. How did Claire feel about the experience of living in the rainforest?93.

Privately, both of us nursed a forlorn (几乎无望的) hope. We joked and laughed, trying to ignore the shadow hanging over the cat sitting very quietly in her arms.2)At 16, Tiger was old for a cat. In quiet dignity（尊严）, he let Gwyn pet him, perhaps understanding that this was a special trip. I glanced at the two as I drove, and thought back to the day when Tiger entered our lives.3)He had been a Christmas present to my second son Brian, handed down—as were his clothes and toys—from his older brother. Sadly, even our dogs had neglected Brian, responding much more eagerly to my commands, and those of my wife and older boy.4)And so, on Christmas Day 1954, I rose early with my wife to put the tiny kitten a neighbor had given us into the stocking that Brian had carefully hung to the mantel（壁炉）the night before. The first of my vivid memories involving Tiger is the look of joy on Brian’s face when he saw the kitten’s face ,when he saw the kitten’s head poking out of the stocking, and heard the plaintive （悲哀的）“meow”that proved his present was alive.5)From then on, Tiger’s life was filled with love. Brian cared for him tenderly, fed him, played with him. For a sometimes rough, sometimes clumsy child, Brian showed a gentleness with Tiger that was amazing. And at midnight, I would invariably find Tiger on Brian’s bed, stretched out beside him.6)My next clear memory of Tiger is also a happy one, which came after near-tragedy. One evening our next-door neighbor rang the front doorbell. “I’m sorry to have to tell you this,”she said when my wife answered the door, “but when I backed out of the driveway this noon, I’m afraid I ran your cat. I tried to help him, but he jumped up and ran away. I don’t know where he went or how badly he was hurt.”7)Four weeks passed with no sign of Tiger. Soldier-like, Brian tried to hide his fear that his friend had crawled away to die. It was a fear we all shared. And we came to accept his death—all of us except Brian.8)Every evening Brian would go to the door and call Tiger’s name. Finally, on the 28th day after the neighbor’s announcement, Brian had an answer. Out from under the front porch came Tiger, his tail high, walking with the pride and majesty（威严）he customarily displayed, behaving as if he had never been away.
