1、The GuitarThe Museum of Fine Arts in the eastern city of Boston recently began showing a collection of guitars. The exhibit is called Dangerous Curves: The Art of the Guitar. It shows how the instrument developed during the past four centuries. Probably no other musical instrument is as popular around the world as the guitar. Musicians use the guitar for almost every kind of music. Country and western music would not be the same without a guitar. The traditional Spanish folk music called Flamenco could not exist without a guitar. The sound of American blues music would not be the same without the sad cry of the guitar. And rock and roll music would almost be impossible without this instrument. Music experts do not agree about where the guitar first was played. Most agree it is ancient. Some experts say an instrument very much like a guitar was played in Egypt more than a thousand years ago. Some other experts say that the ancestor of the modern guitar was brought to Spain from Persia sometime in the twelfth century. The guitar continued to develop in Spain. In the seventeen-hundred it became similar to the instrument we know today. Many famous musicians played the instrument. The famous Italian violinist Niccolo Paganinni played and wrote music for the guitar in the early eighteen hundred. Franz Schubert used the guitar to write some ofhis famous works. One guitar in the Boston Fine Arts display was played by Les Paul. It is a very old electric guitar. Mister Parl began experimenting with ways to make an electric guitar in the nineteen-thirties. The Gibson Guitar Company began producing its famous Les Parl Guitar in 1952. The instrument has the same shape and the same six strings as the traditional guitar, but it sounds very different. The guitar has always been important to blues music. The electric guitar Mister Paul helped develop made modern blues music possible. There have been many great blues guitarists. Yet, music experts say all blues guitar players are measured against one man and his famous guitar. That man is B-B King. Every blues fan knows that years ago B-B King named his guitar Lucille. Lucille is so important to American music that the Smithsonian Institution in Washington D-C has asked for it. They want to display the large, beautiful black guitar in one of the museums because it is a part ofAmerican culture. According to some experts, Spain is one of the oldest countries where guitar was first played. 【单选题】

2、Radiocarbon DatingNowadays scientists can answer many questions about the past through a technique called radiocarbon (放射性碳), or carbon - 14 dating. One key to understanding how and why something happened is to discover when it happened.Radiocarbon dating was developed in the late 1940s by physicist Willard F. Libby at the University of Chicago. An atom of ordinary carbon, called carbon -12, has six protons (质子) and six neutrons (中子) in its nucleus (原子核). Carbon - 14, or C - 14, is a radioactive, unstable form of carbon that has two extra neutrons. It returns to a more stable form of carbon through a process called decay (衰减). This process involves the loss of the extra neutrons and energy from the nucleus.In Libby\'s radiocarbon dating technique, the weak radioactive emissions(放射)from this decay process are counted by instruments such as a radiation detector and counter. The decay rate is used to determine the proportion of C -14 atoms in the sample being dated.Carbon - 14 is produced in the Earth\'s atmosphere when nitrogen(氮) - 14, or N - 14, interacts with cosmic rays (宇宙射线). Scientists believe since the Earth was formed, the amount of nitrogen in the atmosphere has remained constant. Consequently, C -14 formation is thought to occur at a constant rate. Now the ratio of C -14 to other carbon atoms in the atmosphere is known. Most scientists agree that this ratio is useful for dating items back to at least 50,000 years.All life on Earth is made of organic molecules (分子) that contain carbon atoms coming from the atmosphere. So all living things have about the same ratio of C -14 atoms to other carbon atoms in their tissues (组织). Once an organism (有机体) dies it stops taking in carbon in any form, and the C -14 already present begins to decay. Over time the amount of C - 14 in the material decreases and the ratio of C - 14 to other carbon atoms goes down. In terms of radiocarbon dating, the fewer C -14 atoms in a sample, the older that sample is.Radiocarbon is reliable in dating an object back to at least 50,000 years.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:A

答案解析:本题难度不大，答案依据比较明显，主要答案依据在文章第四段最后一句：Most scientists agree that this ratio is useful for dating items back to at least 50,000 years谈到科学家相信，这样的比率对于测定5万多年前的物体有用，题干是其近义解释，所以正确，答案是A。

5、Houses of the FutureWhat will houses be like in thirty years\' time? No one really knows, but architects are trying to predict. _____Future houses will have to be flexible. In thirty years\' time even more of us will be working from home. So we will have to be able to use areas of the house for work for part of the day and for living for the rest. Families grow and change with children arriving, growing up and leaving home. The house of the future will have to grow and change with the family. Nothing will be as fixed as it is now. The house will always be changing to meet changing needs.Everyone agrees that in thirty years\' time we will be living in "intelligent" houses. We will be able to talk to our kitchen machines and discuss with them what to do. Like this, "We\'ll be having a party this weekend. What food shall we cook?" And the machine will tell us what food we will have to buy and how to cook it. We will be able to leave most of the cooking to the machines, just tasting things from time to time to check.The house of the future will be personal, each house will be different. You will be able to change the color of the wall easily.You won\'t have to paint them-you\'ll be able to tell the wall to change the color! And if you don\'t like the color the next day, you will be able to have a new one. The only thing you won\'t be able to do is move the house somewhere else!【单选题】

A.You will be able to change the color of the wall easily.

B.The only thing you won\'t be able to do is move the house somewhere else!

C.And the machine will tell us what food we will have to buy and how to cook it.

D.What will our home be like then?

E.The house of the future will have to grow and change with the family.

F.The kids might take their bedrooms with them as they leave.

正确答案:D

答案解析:本题的难度较大。需要认真阅读文章，特别是第一段和第二段，可用排除法和代入法。本题的上文谈到了没有人会知道30年后房子是什么样子，但建筑家们正在努力地预测。开头第一句用的是疑问句，下文的第一句就谈到未来的房子要十分灵活，用的是陈述句，可以推测此处很可能继续对未来房屋进行发问来展开文章的叙述，回来看选项，可以先排除A，B，C，F项，把D，E代入文章里，可以发现，D更能符合上下文语境和逻辑，是最佳答案。

6、Black HolesMost scientists agree that black holes exist but are nearly impossible to locate. A black hole in the universe is not a solid object, like a planet, but it is shaped like a sphere (球体). Astronomers (天文学家) think that at the center of a black hole there is a single point in space with infinite (无限的) density (稠密).This single point is called a singularity (奇点). If the singularity theory is correct, it means that when a massive star collapses, all the material in it disappears into the singularity. The center of a black hole would not really be a hole at all, but an infinitely dense point. Anything that crosses the black hole is pulled in by its great gravity.Although black holes do exist, they are difficult to observe. These are the reasons,?No light or anything else comes out of black holes. As a result, they are invisible to a telescope.?In astronomical terms, black holes are truly. For example, a black hole formed by the collapse of a giant star would have an event horizon (视界) only 18 miles across.?The nearest black holes would be dozens of light years away from Earth. One light year is about 6 trillion (万亿) miles. Even the most powerful telescopes could not pick out an object so small at such a great distance.In 1994 the Hubble Space Telescope provided evidence that black holes exist. There are still answers to be found, however, so black holes remain one of the mysteries of the universe. (2007年)The nearest black holes are hundreds of light years away from us.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:B

答案解析:题干大意：离我们最近的黑洞也有几百光年。用中心词nearest定位，原文倒数第二段提到：The nearest black holes would be dozens of light years away from Earth. 离地球最近的黑洞有几十光年(dozens)，而不是“hundreds”。故答案选B。

7、AIDSAs a science writer, I don\'t have to wear emotional armor very often. Before I went to Zimbabwe for a visit, I had talked to other reporters who had spent time in Africa. All told me to get prepared for the orphans, many of whom had caught the AIDS virus from their mothers and the strong desire to make everything all right for them. Then again, nothing could have prepared me for the visit to creche(育婴堂) for AIDS orphans in Harare, where one sick, smiling four-year-old boy tried to keep up with the other kids playing ring-around-the-rosy but was so weak he kept falling to the floor, or meeting a 25-year-old unmarried girl who cared for her nephew Only when I got back about a week later The boy who called his aunt "Mama" was too weak even to take the piece of banana I offered. Meanwhile photojournalist Karin Retief was visiting a room at the hospice (济贫院) ______. At first she did not see anyone on the bed and was about to say he must be elsewhere, when suddenly she spotted his tiny arm in the air, his body lost in the folds of the bedclothes. Recently Karin wrote to me that she had been able to keep our assignment from taking too great an emotional suffering at the time. " Only when I got back about a week later, could I moum the people I met", she continued. "I sat in church and wanted to ask the priest to pray for the people with AIDS in Zimbabwe and all over the world. Then all the people\'s faces, pain and suffering became so real, I could not get the words out. I broke down and cried and cried for them". 【单选题】

A.where she had been told a particularly sweet orphan boy stayed

B.who had spent time in Africa

C.Only when I got back about a week later

D.even though her only income was from growing and selling a few vegetables at the local market

E.was so weak he kept falling to the floor

F.while we were visiting the orphans

正确答案:A

答案解析:地点的后面是由where引导的定语从句。因此选A。

8、How to Be a Successful BusinesspersonHave you ever wondered why some people are successful in business and others are not? Here\'s a story about one successful businessperson. He started out washing dishes and today he owns 168 restaurants.Zubair Kazi was born in Bhatkal, a small town in southwest India. His dream was to be an airplane pilot, and when he was 16 years old, he learned to fly a small plane.At the age of 23 and with just a little money in his pocket, Mr. Kazi moved to the United States. He hoped to get a job in the airplane industry in California. Instead, he ended up working for a company that rented cars.While Mr. Kazi was working at the car rental(租赁的) company, he frequently ate at a nearby KFC restaurant. To save money on food, he decided to get a job with KFC. For two months, he worked as a cook\'s assistant. His job was to clean the kitchen and help the cook. "I didn\'t like it," Mr. Kazi says, "but I always did the best I could."One day, Mr. Kazi\'s two co - workers failed to come to work. That day, Mr. Kazi did the work of all three people in the kitchen. This really impressed the owners of the restaurant.A few months later, the owners needed a manager for a new restaurant. They gave the job to Mr. Kazi. He worked hard as the manager and soon the restaurant was making a profit.A few years later, Mr. Kazi heard about a restaurant that was losing money. The restaurant was dirty inside and the food was terrible. Mr. Kazi borrowed money from a bank and bought the restaurant. For the first six months, Mr. Kazi worked in the restaurant from 8 a. m. to 10 p. m. , seven days a week. He and his wife cleaned up the restaurant, remodeled the front of the building, and improved the cooking. They also tried hard to please the customers. If someone had to wait more than ten minutes for their food, Mrs. Kazi gave them a free soda. Before long the restaurant was making a profit.A year later, Mr. Kazi sold his restaurant for a profit. With the money he earned, he bought three more restaurants that were losing money. Again, he cleaned them up, improved the food, and retrained the employees. Before long these restaurants were making a profit, too.Today Mr. Kazi owns 168 restaurants, but he isn\'t planning to stop there. He\'s looking for more poorly managed restaurants to buy. "I love it when I go to buy a restaurant and find it\'s a mess," Mr. Kazi says. "The only way it can go is up. "In the last paragraph, "it\'s a mess" means ______. 【单选题】

A.it\'s small

B.it\'s dirty

C.it\'s profitable

D.it\'s cheap

正确答案:B

答案解析:本题是词义题，难度不大，也是送分题，阅读理解题中的词汇题大多可以通过直接翻查同义词词典直接确定答案。可以确定，mess指“脏乱”，所以答案是B。

9、Dairy Price-fixing ScandalTesco is preparing a legal battle to clear its name of involvement in the dairy price-fixing scandal that has cost consumers ￡270 million. Failure to prove that it had no part in collusion with other supermarkets and dairy processors may land it with a fine of at least ￡80 million. The Office of Fair Trading (OFT) said yesterday that Asda, Sainsbury\'s and the former Safeway, plus the dairy companies Wiseman, Dairy Crest and Cheese Company, had admitted being in a cartel to fix prices for milk, butter and cheese. They were fined a total of just over ￡116 million as part of a leniency deal offered by the watchdog to companies that owned up quickly to anti-competitive behaviour.Officials at the OFT admitted privately that they did not think they would ever discover which company or individual had initiated the pricing formula. But the watchdog recognises that at the time supermarkets were under pressure from politicians and farmers to raise the cost of milk to save dairy farming, though it is not certain that money found its way to farmers. The OFT claimed in September that it had found evidence that the retail chains had passed future milk prices to dairy companies, which then reached a fixed price among themselves.The average cost to each household is thought to be ￡11.25 over 2002 and 2003, Prices went up an extra 3p on a pint of milk, 15p on a quarter of a pound of butter and 15p on a half pound of cheese. There is no direct recompense for consumers, however, and the money will go to the Treasury. The National Consumer Council gave warning that the admissions would dent consumer confidence in leading high street names and that people would become sceptical of their claims. Farmers for Action, the group of farmers that has led protests over low milk prices since 2000, is seeking legal advice on whether it can now bring a claim for compensation.The OFT investigation is continuing, however, in relation to Tesco, Morrisons and the dairy group Lactalis McLelland, and any legal action is expected to be delayed until that is completed. Tesco was defiant and said that it was preparing a robust defence of its actions. Lucy Neville-Rolfe, its executive director, said: "As we have always said, we acted independently and we did not collude with anyone. Our position is different from our competitors and we are defending our own case vigorously. Our philosophy is to give a good deal to customers."Morrisons has supported the OFT in inquiries into the former safeway business that it took over, but in a statement said that it was still making "strong representations" in its defence. A spokeswoman for Lactalis McLelland said that the company was "co-operating" with the OFT. Industry insiders suggested that the three companies were deliberately stalling the OFT investigation.Sainsbury\'s admitted yesterday that it had agreed to pay ￡26 million in fines, but denied that it had sought to profiteer. Justin King, the chief executive, said he was disappointed that the company had been penalised for actions meant to help farmers but recognised the benefit of a speedy settlement. Asda declined to say how much it would pay in fines and also said that its intention had been to help farmers under severe financial pressure.Who is most probably the initiator of the pricing formula?【单选题】

A.Retail chains.

B.Farmers.

C.Dairy companies.

D.Politicians.

正确答案:B

答案解析:细节考查题。题干考查的是，谁最有可能是价格制定的始作俑者。答案参见第二、三段，牧场主机构和牧场主一直在抗议低廉的牛奶价格。由此可以看出最有可能引发牛奶价格发生变化的是牧场主。

10、Animal\'s "Sixth Sense"A tsunami was triggered by an earthquake in the Indian Ocean in December, 2004. It killed tens of thousands of people in Asia and East Africa, Wild animals, however, seem to have escaped that terrible tsunami. This phenomenon adds weight to notions that they possess a "sixth sense" for disasters, experts said.Sri Lankan Wildlife officials have said the giant waves that killed over 24,000 people along the Indian Ocean island\'s coast clearly missed wild beasts, with no dead animals found."No elephants are dead, not even a dead rabbit. I think animals can sense disaster. They have a sixth sense. They know when things are happening" H. D. Ratnayake, deputy director of Sri Lanka\'s Wildlife Department, said about one month after the tsunami attack. The waves washed floodwaters up to 2 miles inland at Yala National Park in the ravaged southeast, Sri Lanka\'s biggest wildlife ______ and home to hundreds of wild elephants and several leopards."There has been a lot of scientific evidence about dogs barking or birds migrating before volcanic eruptions or earthquakes. But it has not been proven," said Matthew van Lierop, an animal behavior assistant at Johannesburg Zoo. "There have been no specialist studies because you can\'t really test it in a lab or field setting," he told Reuters. Other authorities concurred with this assessmetn."Wildlife seem to be able to pick up certain phenmenon, especially birds. There are many reports of birds detecting impending disasters," said Clive Walker, who has written several books on African wildlife.Animals certainly rely on the known senses such as smell or hearing to avoid danger such as predators. The notion of an animal "sixth sense" -or some other mythical power-is an enduring one which the evidence on Sri Lanka\'s ravaged coast is likely to add to. The Romans saw owls as omens of impending disaster and many ancient cultures viewed elephants as sacred animals endowed with special powers or attributes.【单选题】

A.birthplaces

B.playground

C.reserve

D.storage

正确答案:C

答案解析:从上下文判断，本句的意思应该是：Yala国家公园是斯里兰卡野生动物最大的保护区，而birthplaces：出生地，playground：操场，storage：储存，都与上下文表达的意思接不上。reserve：保护区。因此，选项C是答案。
