1.The world's oceans have warmed 50 percent faster over the last 40 years than previously thought due to climate change, Australian and US climate researchers reported Wednesday．Higher ocean temperatures expand the volume of water, contributing to a rise in sea levels that is covering small island nations and threatening to destroy the low-lying, densely-populated low regions around the globe. 　　The study, published in the British journal Nature, adds to a growing scientific chorus of warnings about the pace and consequences rising oceans．It also serves as a corrective to a massive report issued last year by the Nobel-winning UN Intergovernmental Panel on Climate Change (IPCC), according to the authors. 　　Rising sea levels are driven by two things: the thermal expansion of sea water, and additional water from melting sources of ice．Both processes are caused by global warming．The ice sheet that sits atop Greenland, for example, contains enough water to raise world ocean levels by seven meters, which would bury sea-level cities from Dhaka to Shanghai. 　　Trying to figure out how much each of these factors contributes to rising sea levels is critically important to understanding climate change, and forecasting future temperature rises, scientists say．But up to now, there has been a puzzling gap between the projections of computer-based climate models, and the observations of scientists gathering data from the oceans. 　　The new study, led by Catia Domingues of the Centre for Australian Weather and Climate Research, is the first to reunite the models with observed data．Using new techniques to assess ocean temperatures to a depth of 700 meters from 1961 to 2003, it shows that thermal warming contributed to a 0.53 millimeter-per-year rise in sea levels rather than the 0.32 mm rise reported by the IPCC.

Parents feel that it is difficult to live with teenagers．Then again，teenagers have31feelings about their parents，saying that it is not easy living with them．According to a recent research，the most common32between parents and teenagers is that regarding untidiness and daily routine tasks．On the one hand，parents go mad over33rooms，clothes thrown on the floor and their children's refusal to help with the34．On the other hand，teenagers lose their patience continually when parents blame them for35the towel in the bathroom，not cleaning up their room or refusing to do the shopping at the supermarket．The research，conducted by St．George University，shows that different parents have different36to these problems．However，some approaches are more37than others．For example，those parents who yell at their children for their untidiness，but38clean the room for them，have fewer chances of changing their children's39．On the contrary，those who let teenagers experience the40of their actions can do better．For example，when teenagers who don't help their parents with the shopping don't find their favorite drink in the refrigerator，they are forced to41their actions．Psychologists say that42is the most important thing in parent-child relationships．Parents should43to their children but at the same time they should lend an ear to what they have to say．Parents may44their children when they are untidy but they should also understand that their room is their own private space．Communication is a two-way process．It is only by listening to and45each other that problems between parents and children can be settled.36A.approaches,B.contributions,C.introductions,D.attitudes

6.Passage FourAt the 1893 Columbian Exposition,a World Fair held in Chicago,chocolate-making machinerymade in Germany was displayed.It caught the eye of M.S.Hershey,who saw the potential forchocolate.He installed chocolate machinery in his factory in Lancaster,and produced his firstchocolate bars in 1894.Other Americans began mixing in other materials to make up new candy bars throughout the end of the 1890's and the early 1900's.But it was World War l that really brought attention to the candy bar.The U.S.Army Quartermaster Corps requested various American chocolate manufacturers toprovide 20 to 40 pound blocks of chocolate to be shipped to quartermaster bases.The blocks were cut into smaller pieces and distributed to American soldiers in Europe.Eventually the task of making smaller pieces was turned back to the manufacturers.By the end of the war when the soldiers arrived home,the American candy bar business was assured.Why?Because the returning soldiers had grown fond of chocolate candy and wanted more of the same.As a result,from that time on and through the 1920's,candy bar manufacturers became established throughout the United States,and as many as 40,000 different candy bars appeared on the scene.The original candy bar industry had its start on the eastern coast in such cities as Philadelphia,Boston,and New York.The industry soon spread to the Midwest because shipping and raw materials such as sugar,corn syrup,and milk were easily available.Chicago became the seat of the candy bar industry and is even today an important base.48.Why did M.S.Hershey start the production of chocolate bars?

7.The clothes a person wears may express his ______or social position.

8.Jane has sent several letters,but___of them have been answered.

9.Passage TwoThere are many commonly held beliefs about eyeglasses and eyesight that are not proven facts. For instance, some people believe that wearing glasses too soon weakens the eyes. But there is no evidence to show that the structure of eyes is changed by wearing glasses at a young age. Wearing the wrong glasses, however, can prove harmful. Studies show that for adults there is no danger, but children can develop loss of vision if they have the wrong glasses.We have all heard some of the common myths about how eyesight get bad. Most people believe that reading in dim light causes poor eyesight, but that is unique. Too little light makes the eyes work harder, so they do get tired and strained. Eyestrain also results from reading a lot, reading in bet, and watching too much television. But although eyestrain may cause somepain or headaches, it does not permanently damage eyesight.Another myth about eyes is that they can be replaced, or transferred from on person to another. There are close to on million verve fibers that connect the eyeball to brain, and as if yet it is impossible to attach them all in a new person, Only certain parts of the eye--the cornea and the "retina--can be replaced. But if we keep clearing up the myths and learning more about the eyes, someday a full transplant may be possible! This passage is mostly about__________.

12.There is nothing more possible than a new hip or knee that can put the spring back inyour step.Patients receiving joint implants(移植）often are able to resume many of thephysical activities they love,even those as vigorous as tennis and hiking.No wonder.then,that joint replacement is growing in popularity.In the United States in 2007,surgeons performed about 806,000 hip and knee implants(the joints most commonly replaced),double the number performed a decade earlier.Though these procedures have become routine,they are not failure free.implants must sometimes be replaced,said Dr.Henrik Malchau,an orthopedic surgeon(矫形外科医生）at Massachusetts General Hospital in Boston.A study published in2007 found that 7 percent of hips implanted in Medicare patients had to be replaced withinseven and a half years.The percentage may sound low,but the finding suggests that thousands of hip patients eventually require a second operation,said Dr.Malchau.Those patients must endure additional recoveries,often painful,and increased medical expenses.Thefailure rate should be lower,many experts agree.Sweden,for instance,has a failure rate estimated to be a third of that in the United States.Sweden also has a national jointreplacement registry,a database of information from which surgeons can learnhow andwhy certain procedures go wrongA registry also helps surgeons learn quickly whetheraspecifictype of implant is particularly problematic,"Every country that has developedaregistry has been able to reduce failure rates."“Significantly,"said Dr.Daniel Berry,chief of orthopedic surgery at the Mayo Clinicin Rochester,Minn.A newly formed American Joint Replacement Registry will begin gathering data fromhospitals in the next 12 to 18 months.It's good news for those who are considering replacing a knee or hip.People who need a new kneeor hip would possiblyfeelabout data gathering inthe U.S.（）
