People afraid of speaking in public are suffering fr om “Stage Fright”. Stage fright makes a person 36 . Inthat 37 it can make one’s mind go blank and 38 what one ought to say, or to act. Actors, musicians, dancers, lawyers, even TV show hosts suffered from stage fright at one time or another. Diana Nichols is an expert in helping people free from stage fright at a medical center in New York City. She helps actors learn to 39 themselves. Miss Nichols says some people have always been 40 to perform before the audience. Others, she says, develop stage fright after a terrible experience.She offers them advice to control the fear. One way is to smile before going onto the stage. Taking two deep breaths also helps. Deep breathing helps you get control of your body.Miss Nichols asks her 41 to tell themselves that their speech or performance does not have tobe 42 . It’s all right to make a mistake. She tells them they should not be too nervous while they are performing. It is important that they should continue to perform while she is helping them. After each performance, they discuss whathappened and find out what 43 helped and what did not. As they perform more and more, they will 44 less and less.

Post- it Notes, the pieces of paper that you can fasten almost anywhere and then remove without leaving any sign that they were there, are an example of such an invention.Post-it Notes were invented 20 years ago by Art Fry, a scientist at 3M Company. The idea came from a frustrating experience while singing. Fry used pieces of paper as bookmarks to mark the places in his book of songs, but these bookmarks were always falling out. He knew he needed a bookmark that would stay where he put it without damaging the pages.Around that time, Fry heard that his workmate, Dr. Spence Silver had created a new adhesive (粘合剂) whichwas special because it was sticky, but not too sticky. It was strong enough to hold papers together, but weak enough to not tear the paper when it was removed. Fry saw that the new adhesive could help solve his bookmark problem. One morning, Fry put some of the adhesive on the top of a piece of paper. Just as he hoped, it made a perfect bookmark.Later, Fry realized that his new invention can also be used as a great bookmark. He came to this idea when he wrote a note on one of his new “bookmarks” and attached it to a report he was going to give to a workmate. Soon, the workmate asked Fry for more samples of his invention so that they could use the new type of notes themselves.When some salespeople at 3M went to offices and showed workers just how helpful the new type of notes could be, they immediately received many orders. As more and more people discovered how useful Post-it Notes could be, the product took off.46.

Signs like that have a way of attracting small children, and sure enough, a little boy appeared under the store owner’s sign.“How much are you going to sell the dogs for?” he asked.The store owner replied, “Anywhere from $30 to $50.”The little boy reached in his pocket and pulled out some change. “I have $2.37,” he said, “Could I look at them?”The store owner smiled and took the boy to the dog nest. To our surprise, the little boy selected limping dog and said, “What’s wrong with that little dog?”The store owner explained that a doctor had examined the little dog and had discovered it don’t have a hip socket(膝盖骨). It would always limp.The little boy became excited, “That’s the dog I want to buy.”The store owner said, “No, you don’t want to buy that little dog. If you really want him, I will just g ive him to you.”The little boy got quite upset. He looked straight into the store owner’s eyes, pointing his finger, an d said, “I don’t want you to give him to me. That little dog is worth as much as all the other dogs and I’ll pay full price. In fact, I will give you $2.37 now, and 50cents a month until I have paid all the money for him. ”The store owner said, “You really don’t want to buy this little dog. He is never going to be able to run and jump and play with you like the other dogs.”To his surprise, the little boy revealed a badly, disabled left leg supported by a big metal brace.

Glancing up, he saw a large wasp nest under the roof. Allen had heard that wasps can became more likely to sting in summer. He mentioned this to Mrs. Carey, who had opened the door.“Oh, they don’t bother me,” she said lightly. “I go in and out all the time.”Anxiously, Allen looked at the nest again—to see the wasps flying straight at him. “Hurry!” he shouted to Mrs. Carey. “Get in!”She stepped quickly inside. Allen ran for his mini-bus. Too late; they were upon him. Just as he jumped aboard, half a dozen red spots showed on his arm, and he felt more on his back and shoulders.As he was driving down the road, Allen felt as if something was burning at the back, and the “fire” was spreading forward toward his face. And immediate anxiety took hold of him. Allen knew that stings could cause some persons to die. But he had been stung the previous summer and the after-effects soon passed. However, what he didn’t know was that the first sting had turned his body into a time bomb waiting for the next to set off an explosion.Miles from the nearest medical assistance, Allen began to feel his tongue thick and heavy and his heartbeat louder. Most frightening, he felt his breathing more and more difficult. He reached for the radio mike, trying to call the mini-bus centre, but his words were hardly understandable. Signals were also poor that far out. He knew a rescue team was on 24-hour duty at the Amherst Fire Department’s north station. So his best chance was to make a run for it.Rushing down the mountain, Allen tried not to panic, focusing his mind on each sharp turn. He was almost through the last of them when he felt sure he was going into shock. Just then he reached for the radio mike again.“Call fire station,” he shouted concentrating to form the words. “Emergency. Bee sting. Emergency. There in ten minutes.”“Five-ten,” the center replied.Hold on, Allen thought. Keep your eyes open. Breathe. Keep awake.At last he reached the station. Two firemen ran out. Allen felt their hands grasp him before he hit the ground. You made it, he thought.26.It is mentioned in the passage that wasps are more likely to attack when_______.A. there are huge noisesB. strangers are getting very nearC. the air is filled with food smellD. the hottest season comes around27. Allen didn't know that if stung by wasps again, he would___________.A. have no after-effectsB. suffer from sharper painC. lose his lifeD. became much weaker28. Allen failed at the first time when he tried to send his message to the mini-buscenter because__________.A. he was unable to speak clearlyB. his radio equipment was poorC. he was in a state of shockD. no one was on duty29. Which of the following is NOT true according the story?A. Allen drove to the fire station because he knew there was a rescue team there.B. Allen managed to make his request of help clear though he had difficultytalking by then.C. The mini-bus centre did help in that they got the rescue team ready beforeAllen arrived.D. Allen shouldn’t have looked at the wasps when he helped Mrs. Carey.30. Which would be the best title for the passage?A. Allen, a Helpless DriverB. Wasps, Bloody KillersC. A Race against DeathD. War against WaspsB"The world's oceans are slowly getting more acidic,” say scientists. The researchers from California report that the change is taking place in response to higher levels of carbon dioxide in the atmosphere.The lowering of the waters’ PH value is not great at the moment but could cause a serious threat to current ocean life if it continues, they warn. Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature.Increasing use of oil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by sea water. Once in the water, it reacts to form carbonic acid. Scientists believe that the oceans have already become slightly more acidic over the last century.These researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change．"This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere," said Dr Caldeira. "And we predict the amount of future acidity will exceed anything we have seen over the last several hundred million years, let alone perhaps after rare disasters such as asteroid impacts．”However, it is not absolutely clear what that means for ocean life．Most organisms live near the surface, where the greatest PH change would be expected to occur, but deep-ocean life forms may be more sensitive to PH changes．Coral reefs(珊瑚礁) and other organisms whose shells contain calcium carbonate may be particularly affected if the water's acidity levels keep going up, the team predict. They could find it much more difficult to build these structures in water with a lower PH.In recent years some people have suggested storing carbon dioxide from power stations in the deep ocean as a way of dealing with global warming．But Dr Caldeira said that such a strategy should now be re-considered. "Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing-because in releasing CO2 into the atmosphere we warm the planet, and when CO2, is absorbed by theoce an, it reduces the amount of greenhouse warming.”31. The ocean is becoming more acidic due to___________.A. the lower water PH valueB. the warming atmosphereC. the higher level of CO2 in the airD. the increasing use of oil fuels32. According to Dr Caldeira,__________ .A. ocean absorption of carbon dioxide is a good thingB. more oil fuels will be used in the near futureC. scientists may predict climate changes with computer modelsD. the future situation of the amount of acidity is extremely serious33. If the water's acidity level keeps rising,_________ .A. ocean life whose structures contain calcium carbonate may be affectedB. the waters’ PH value will become higher and higherC. organisms living near the surface are more sensitive to PH changesD. some disasters will occur more often than before34. What does the underlined word “acidic” probably mean?A. 污染的B. 酸的C. 复杂的D. 温暖的35. The purpose of this passage is to_________ .A. show people the findings of a research teamB. inform people of how acid the ocean is nowC. introduce Dr Caldeira and his team's researchD. warn people of the higher acidity level in the seaCJames Cleveland Owens was the son of a farmer and the grandson of black slaves. His family moved to Cleveland when he was 9. There, a school teacher asked the youth his name.“J. C.,” he replied.She thought he had said “Jesse”, and he had a new name.Owens ran his first race at age 13. After high school, he went to Ohio State University. He had to work part time so as to pay for his education. As a second-year student, in the Big Ten games in 1935, he set even more records than he would in the Olympic Games a year later.A week before the Big Ten meet, Owens accidentally fell down the stairs. His back hurt so much that he could not exercise all week, and he had to be helped in and out of the car that drove him to the meet. He refused to listen to the suggestions that he give up and said he would try, event by event. He did try, and the results are in the record book.The stage was set for Owens’ victory at the Olympic Games in Berlin the next year, and his success would come to be regarded as not only athletic but also political. Hitler did not congratulate any of the African-American winners.“It was all right with me,” he said years later. “I didn’t go to Berlin to shake hands with him, anyway.”Having returned from Berlin, he received no telephone calls from the president of his own country, either. In fact, he was not honored by the United States until 1976, four years before his death.Owens’ Olympic victories made little difference to him. He earned his living by looking after a school playground, and accepted money to race against cars, trucks, motorcycles, and dogs.“Sure, it bothered me,” he said later. “But at least it was an hone st living. I had to eat.”In time, however, his gold medals changed his life. “They have kept me alive over the years,” he once said. “Time has stood still for me. That golden moment dies hard.”36. Owens got his other name when __________.A. he went to Ohio State UniversityB. his teacher made fun of himC. his teacher took “J. C.” for “Jesse”D. he won gold medals in the Games 37．In the Big Ten meet, Owens _________.A. hurt himself in the backB. was weak but determined to winC. tried every sports event but failedD. had to give up some events 38．Owens received no telephone calls from the president because _________.A. he was not of the right raceB. he was the son of a poor farmerC. he didn’t shake hands with HitlerD. he refused to listen to the suggestions that he give up39. Which of the following shows the correct order of James’ life?a. James worked part time to get the fee for schoolb. He was honored by the USc. He got success at the Olympic Gamesd. James set many records in Big Ten Gamese. He went to Cleveland with his familyf. Owens fell down and hurt his backA. a,e,f,d,b,cB. e,a,d,f,b,cC. a,e,d,f,c,bD. e,a,f,d,c,b40.

They have encouraged him to overcome difficulties in lifeD. They have kept him busy with all kinds of jobsDItalian Lakes and Greek Islands (12 Days)Prices starting from＄1,999Your tour begins in Milan, Italy, and moves on to the pretty Italian Lake District and the attractive resort of Stresa, your home for two nights.
