At the close of the Spanish-American War the United States bought a piece of land ten miles across the Isthmus. Immediate attention was given to the control of illnesses.

Inc, an environmental research organization in New York.”By 2005, the group predicts, about 65,000 tons will “retire” every year in the US.Not only do these phones add to the landfill waste but the toxin(霉素) they give out are damaging the environment.The phones contain toxic chemicals that have been associated with cancer and neurological(神经(de)) disorder.The toxin do not degrade(分解), but “increase in large number in the environment and can damage the ecosystem, moving up the food chain as people eat plants, livestock and seafood,” said Eric Most, director of Inform’s Solid Waste Prevention program.The situation is so bad that the US Environmental Protection Agency has given Inform Inc. a grant to study cell phone collection and donation programs.51. According to the passage, if Americans don’t like their cell phones, the best way is to _______A. put them in incineratorsB. bury them under the groundC. put them into the seaD. donate to charities52. Which of the following doesn’t belong to the ill effect of toxinsA. cancerB. damage of the ecosystemC. less incomeD. neurological disorders53. After reading the passage, we know________A. toxic materials are easy to degradeB. US Environmental Protection Agency paid more attention to the recyclingof cell phones.C. take-back plans for cell phones will be easy to carry out in the US.D. cell phones have more disadvantages than advantages in our daily lifeBThere is a sandy beach on the coast on Hawaii that is known as the world-famous Waikiki Beach. At some points on Waikiki Beach, however, the sand is only wide enough for two or three people to lie down between solid land and Pacific Ocean waters. “It used to be big. Now it’s crowded, and everyone is bunched together,” a local person said. “The water is too close.” The beach has shrunk by about a foot per year over the past five decades. If it’s not cared for, Waikiki Beach will eventually disappear entirely.According to the scientists, the problem isn’t caused by heavy use by the 70,000 tourists who walk on the islands each day. The main reason is a sand shortage caused by shoreline development, including sea walls and other man-made structure.Beach shrinking is common worldwide. The usual way to save it is to bring more sand, but that hasn’t been done at Waikiki since the 1970s. State officials are testing a sand –pumping project to repair the beach using offshore sand, which means that it won’t be necessary to import sand fromother countries. The plan is to dredge 10,000 cubic yards of sand from about a half –mile offshore, then pump it back to the beach.The ＄425,000 test program gives beach lovers hope that Waikiki could be returned to its original size, but it could cost as much as ＄25 million to repair the entire beach.State officials say that the plan to dredge and pump sand is environmentally friendly, because it recycles the same sand that wasoriginally part of the beach. If successfully, they say the project could become a model for repairing more of Waikiki and other fading Hawaiian beaches.54. What happened to Waikiki BeachA.It was ruined by the millions of tourists every year.B. A sand –pumping project is being carried out on the beach.C.At any points, it is only wide enough for two or three people to liedown.D. A project to repair the beach is being tested now.55. The underlined word “shrink” probably means “_______”A.be quickB.be slowC.become biggerD.become smaller56. According to the scientists, why does Waikiki Beach become smallerA.There are too many tourists walking on the beach every day.B.The government isn’t paying much attention to this case.C.There is a sand shortage caused by shoreline development.D.The sand has been taken away by the strong wind.57. What can we learn about the sand pumping projectA. The project is harmless to the environment.B. There used to be another similar project in HawaiiC. The local government will pay for everything.D. It will cost about ＄425,000 to repair the whole beach.CI was born in Tuckahoe, Talbot Country, Maryland. I have no accurate knowledge of my age, never having seen any record containing it. By far the largest part of the slaves know as little of their age as horses knows of theirs, and it is the wish of most masters within my knowledge to keep their slaves thus ignorant. I do not remember having ever met a slave who could tell of his birthday. They seldom come nearer to it than planting-time, harvesting, springtime, or fall time. A lack of information concerning my own was a source of unhappiness to me even during childhood. The white children could telltheir ages, I could not tell why the same right ought to be taken away from me.I was not allowed to ask my master about it. He considered all such questions on the part of a slave improper and impolite. The nearest estimate I can give makes me now between 27 and 28 years of age. I come to this, from hearing my master say, some time during 1835, I was about to 17 years old. My mother was named Harriet Bailey. She was the daughter of Issac and Betsey Bailey, both colored, and quite dark.My father was a white man. The opinion was also whispered that my master was my father; but of the correctness of this opinion, I know nothing and I had nomeans to know. My mother and I were separated when I was an infant—before I knew her as my mother. It is a common custom, in the part of Maryland from which I ran away, to part children from their mothers at a very early age. Frequently, before the child has reached its twelfth month, its mother is taken from it, and hired out on some farm a considerable distance off, and the child is placed under the care of an older woman, too old for field labor.58. It can be learned form the text that________A. the slaves forgot the exact time when they were bornB. the writer didn’t know whether his master was his fatherC. the writer was about 27 in 1835D. the writer’s mother left him as soon as he was born59. The underlined word “it” in paragraph 1 refer to_______A. their birthdayB. my ageC. a recordD. Maryland60. How does the writer feel about not knowing his ageA. curiousB. unhappyC. astonishedD. excitedDAfter many days of anxious waiting, the Olympic mascots（吉祥物）were finally chosen at eight p.m. on November 11,2005. This marks the start of the 1,000-day countdown to the 2008 Beijing, Olympic Games.The Olympic mascots are the Olympic flame, the fish, the panda, the Tibetan antelope and the swallow. They are designed to express the playful qualities of five little children who form an intimate circle of friends.Beijing officially started to select the mascots in August 2004. A range of animals and cartoon figures participated in the fierce competition. Thelucky five won over other candidates such as the Chinese dragon and the Monkey King, which had been favorites along the way.“I’ve always been confident in the whole process, because I’m the most precious animal in China. That means I got lots of votes,” said the panda, when Teens interviewed him.He was right. Although some people said he should not have been chosen because he was the mascot of the 1990 Asian Games, he won the support of the majority. Named “Jingjing”, he was chosen because he makes children smile and brings the blessing of happiness wherever he goes. He was chosen to show China’s desire to protect nature.Unlike the well-known panda, the Tibetan antelope is considered much more sporty than other chosen animals.“I can run 70-100 km pre hour at a high altitude where the oxygen levelis just half that of the plains. So you see, I’m a perfect symbol for the spirit of the Olympics——higher, faster and stronger,” claimed the “athlete”, whose name is “Yingying”.The fish, “Beibei” stands for prosperity. She will represent water sports. “Nini”, the swallow, stands for good luck and desire for a better life. She will represent gymnastics. The Olympic flame, “Huanhuan”, shows enthusiasm and best wishes for the Olympics. He will represent ball games.Many teenagers are surprised that Beijing will have five mascots but very excited that they will have more choice when shopping for souvenirs.“Stickers with pandas and Tibetan antelopes on them will be popular among girls. They will also raise teenagers’ awareness of animal protection,” said Jiang Juan, a Senior 2 girl from Hunan Province.However, Zhang Zhang, 17, from Shanxi Taiyuan No.5 High School is hoping for more: “I hope there will be a cartoon in which the five are the main characters, doing different sports. So the whole world will have a better understanding of the Chinese spirit.”61. _______ represents the sports, such as diving, surfing, swimming and so on.A. JingjingB. NiniC. HuanhuanD. Beibei62. The underlined word “that” (Para.7) refers to _______.A. a high altitudeB. 70-100 km per hourC. the oxygen levelD. the spirit of the Olympics63. What does the passage center onA. The introduction made to the 2008 Olympic mascots.B. Teenagers’ opinions released about the 2008 Olympic mascots.C. The reason why the five are chosen as the 2008 Olympic mascots.D. The mark of the start of the 1,000-day countdown to the 2008 Beijing,Olympic Games.E“What’s your English name ” I asked in my first oral class. “Goat,”came the reply. I tried to keep myself from laughing, as I’m sure the poor boy had no idea of the other meanings associated with the word goat: “a dirty old man” or “a foolish person”.Later, my thoughts turned to why Chinese students take an English name. Obviously, for foreign teachers such as me, English names help us to learn names and recognize students more rapidly. And it’s a means of easily setting up communication with Westerners.As Sharon, a student displays her knowledge of western culture and ideas. Once Sharon has graduated, if she is fortunate to find employment thatinvolves regular communication across international boundaries, relationships will be smoothed if others can easily remember her name.Parents in English-speaking countries do not usually choose words at random to name their child. For every parent who seeks to be truly creative by inventing a unique name, there will be nine others selecting from a recognized book of names. These books have been passed on from generation to generation.While English names do have meanings, this is rarely of great importancefor parents in making their choice. Often, associations with heroes, pop idols will influence a decision.There are a great many names to choose from, and at any one time some will be more fashionable than others. When our present Queen was crowned, many baby girls were christened Elizabeth, while Princess Diana’s marriage to Charles led to a generation of Dianas. Most parents seeking to be original or unique look through lists for names that haven’t been used regularly in recent years. So, if you are thinking of taking an English name, stop and think. You have a unique opportunity to choose a new identity for your English speaking relationships in the future. Before you accept any old name, make sure you are happy with its sound, its meaning and its associations.。
