2013学年奉贤区调研测试高三英语试卷(2014,01)II. Grammar and V ocabularySection A(A)When I was young I wanted to be a model, so I convinced my parents to take me for an audition (试演).I was (25) (select)and told I had potential.I imagined (26) (sign) by some famous model companies.For months, any boredom or disappointment I faced was pushed aside because I knew I (27) ( have ) the chance to be a real model soon.Of course, I wasn't signed, but (28) hurt the most was being told that if I grew to 1.75 meters I could be a success.I prayed for a growth spurt (冲刺)because I didn’t want to give up my dream.I made an appointment with a local modeling agency.The agency sent me out on a few auditions, but with every day I didn't receive a call, I grew more (29) (depress).The final straw came in July (30) I had decided to focus on commercial modeling.There was an open call in New York City.We spent hours driving, only to be told that I was too short.Years later, I realize that the trip to New York was good as (31) made me notice I didn't actually love modeling, just the idea of it.I wanted to be special and I was naively determined(32) (reach) an impossible goal.The experience has made me stronger and that will help me later in the future.(B)The cold came a little bit earlier this winter. The weather has been harsh and unforgiving.Beijing witnessed the (33) (early) snowfall since the 1950s on Nov 3. Temperatures in many parts of China have hit record lows, with Inner Mongolia suffering from a killer cold of -40 C. Cold weather also brought heavy snowstorms (34) the US, Russia and Europe, (35)(cause) deaths and forcing highways to shut down.You may not think they are related in any possible way, but scientists say that the extreme cold started in the North Pole, where the sea ice is melting rapidly (36) the burning of fossil fuels. This summer, the National Snow and Ice Data Center in the US announced that the sea ice coverage in (37) Arctic had reached its lowest level with less than half of the coverage it has four decades ago.Large amounts of sea ice loss could change (38) air circulates in the atmosphere. At the same time, melting sea ice also release more ocean water, which result in increased water vapor in the atmosphere that (39) be transferred into snow.Also, the attack of the cold came quickly and without a break this year. This left no time for the temperature to revive(回升),(40) caused the cold to accumulate.III .Reading ComprehensionSection A PRINCE Harry of Wales, Scottish actress Karen Gillan, Ron Weasley from the wizard movie Harry Potter – what do they have 51 ? They all have ginger hair, or as people usually say, they are all “redheads”.Britain may be the most red-headed country in the world. About 1 to 2 percent of the world's population has red hair, but in the UK the numbers are much 52 , with 13 percent of Scots, 10percent of the Irish, and 6 percent of people in England having red hair, according to the BBC.Scientists have tried to explain why some people have red hair for some time and now they may have found an answer: the dull 53 in Britain.“I think it is to do with the sunshine,” said Alistair Moffat, the headmaster of St Andrews Univer sity, UK. The human body needs vitamin D from 54 , but unfortunately people living in Britain do not have enough of it because of its maritime climate. 55 , Britain gets even more cloud than countries in the far north of Europe. In Sweden, for example, the average daily hours of sunshine is 5.4. In Scotland it is only 3.1 hours.To 56 this, the DNA of people living in these areas has changed 57 ; scientists call this a mutation(变异). Originally, the 58 on our body is a mixture of two kinds of melanin - black melanin(黑色素)and red/yellow melanin, but with certain parts of DNA59 , the production of black melanin is suppressed while only red/yellow melanin is made. The60 is red hair, light skin color, freckles(雀斑)and a greater 61 to sunlight.“We need 62 skin to get as much Vitamin D from the sun as possible,” added Moffat 63 , what's more interesting is that redhead DNA mutation is recessive, which means it is hidden and can often 64 generations without showing.“At least 1.6 mill ion Scots carry a red-head gene mutation, and most are 65 that they do.,” Moffat said .This is why a person who does not have red hair can still produce red-haired children if he or she is a carrier of this special DNA.51.

Most of the time I am simply doing finger exercises, another form of piano practice without the beautiful notes. Sometimes, however, I receive a gift, reminding me of the gifts in my life. The following passage is one of those gifts.Peter Jones is a 92-year-old, calm and face proud man. Every morning he is fully dressed by eight o’clock, with his hair fashionably combed and face perfectly shaved, even though he is unable to see. He would move to a nursing home today. His wife of 70 years recently passed away, making the movenecessary.After hours of waiting patiently in the entrance ball of the nursing home, he smiled sweetly when told his room was ready. As he moved his walker skillfully to the elevator, the nurse provided a visual description of his tiny room. “I love it,” he stated with the ebullience of an eight-year- old having just been presented with a new pet dog.“Mr.Jones, you haven’t been to the room,” said the nurse.“That doesn’t have anything to do with it,” he replied. “Happiness is something you decide on ahead of time. Whether I like my room or not doesn’t depend on how the furniture is arranged... it’s how I arrange my mind. I have already decided to love it. It’s a d ecision I make every morning when I wake up. I have a choice: I can spend the day in bed complaining of difficulty I have with parts of my body that no longer work, or get out of bed and be thankful for the ones that do. Each day is a gift, and as I am ali ve, I’ll focus on the new day and all the happy memories I’ve stored away.”May each of our days continue to be a gift.66.What do we know about Mr. Jones?A.

Students can get their student cards from the Library.(C)The research carried out by the University of Bari in Italy could help clarify hospitals who are charged with wasting money on art and decoration as it suggests a pleasant environment helps patients overcome discomfort and pain.A team headed by Professor Marina de Tommaso at the Neurophysiopathology Pain Unit asked a group of men and women to pick the 20 paintings they considered most ugly and most beautiful from a selection of 300 works by artists such as Lenoardo da Vinci and Sandro Botticelli. They were then asked to watch either the beautiful paintings, or the ugly paintings, or a blank panel while the team struck a shortlaser pulse at their hand, creating a sensation as if they had been hurt by a pin. The subjects rated the pain as being a third less intense while they were viewing the beautiful paintings, compared with when considering the ugly paintings or the blank panel.Electrodes (电极) measuring the brain’s electrical activity also confirmed a reduced response to the pain when the subject looked at beautiful paintings. While distractions(娱乐), such as music, are known to reduce pain in hospital, Prof de Tommaso says this is the first result to shoe that beauty plays a part. The findings, reported in New Scientist, also go a long way to show that beautiful surroundings could aid the healing process.“Hospitals have been designed to be functional, but we think that their aesthetic(审美能力)aspects should be taken into account too,” said the neurologist. “Beauty obviously offers a distraction that ugly paintings do not. But at least there is no suggestion that ugly surroundings make the pain worse. I think these results show that more research is needed into the how a beautiful environment can reduce suffering.”Pictures they liked included Starry Night by Vincent V an Gogh and Botticellis’ Birth of Venus. Pictures they found ugly included works by Pablo Picasso, the Italian 20th century artist Anonino Bueno and Columbian Fernando Botero. “these people were not art experts so some of the pictures they found ugly would be considered masterpieces by the art world,” said Prof de Tommaso.74. According to the first paragraph, people didn’t approve_______________.A. hospitals spend money on medical equipmentB. hospitals decorate their rooms with works of artC. hospitals make their environment pleasant to patientsD. hospitals treat patients with works of art75. How did the researchers make the research?A. By asking the subjects to listen to music.B. By requiring the subjects to draw paintings.C. By ordering the subjects to choose which picture is beautiful and ugly.D. By aching the subjects’ hands while they are watching paintings.76.According to the research, when designing a hospital, we should consider its____________.A. convenient facilitiesB. functional operating roomC. pleasing environmentD. bright waiting room77.The best title for the passage may be___________________.A. Patients Don’t Like PicturesB .Arts Can Be Used As a MedicineC. Ugly Patients Feel Less PainD. Beautiful Art Can Ease PainSection CMost people look forward to retirement as a time they can finally take can finally take up activities that they never had the time or energy to pursue before. But some recent studies on people in their golden years are disturbing: they suggest that retirees are more likely to suffer from depression and possibly higher rates of other diseases such as heart disease and high blood pressure. That’s shy a new study of French workers is welcome news.Led by Hugo Westerlund, a professor of psychology at Stockholm University, the study of more than 14,000 workers found lower rates of depression and fatigue in people after got tired while they were still employed.The scientists followed the employees of the French national gas and electric company for 14years. They found in the year immediately after retirement, the volunteers reported 40% fewer depressive symptoms than they had in the year before their retirement. The researchers also found an 81% drop in reports of both mental and physical fatigue over the same time period.Clearly, said Westerlund, much of these decrease in physical and mental fatigue can be traced back to relief from the stresses of work. The decline in depressive symptoms suggests that retirement may be having a positive mental effect, too, which may have a lot to do with the generous pensions (养老金) that French workers enjoy. Most retirees in that country still benefit from about 80% of their yearly salaries.“The economic or financial situation in retirement is very important,” Westerlund says,” We don’t know if the decrease in fatigue and depressive symptoms is because of the removal of something bad while in work or the addition of something good while in retirement. But no matter the reason, if life in retirement is not comfortable, then we won’t see the improvements we did.”However, in European nations like France, governments are considering changes to pension plans, which may affect retirees’ health after they leave their jobs --- with less of a financial safety net, workers may no longer seem so mentally and physically happy to be out of work.78. According to some recent studies, retired people may have depression and higher rates of other diseases like______________________.79.
