The dams① aimed at saving Venice from the waves have been backed greatly. After eight years of argument, it plans to build 79 gates across three channels connecting the lagoon around Venice with the Adriatic Sea. The gates would be open most of the time but would be closed if there is a danger to the city.
The project, though, has run into fears that it could worsen Venice’s problems. The city throws waste into the lagoon, and environmentalists fear the dams will cause this pollution to become worse if there is no tide to wash it out regularly. But if there is a tide, the flow can wash away about 550 million cubic meters of the lagoon in a single day, which means that by leaving the dam open for only a few hours, the waste should be cleaned out.
Another piece of good news is that British scientists are confident that the dams will be able to face an expected rise in sea levels caused by global warming. The gates are designed to stand a 22-centimetre rise in sea levels, but many scientists expect a global rise in sea levels of 31cm by 2100.
However, Trevor Davies and Isabel Trigo from University of East Anglia believe the dams are unlikely to broken. Climate change will weaken the local storms in the Adriatic that are the main cause of flood risk. Floodwaters are also a seasonal danger in Venice, usually because of a combination of spring tides and strong winds.
Venice, which rests on wooden piles driven into boggy③ ground, has been sinking for centuries, worsening the encroachment by the sea.
Notes:
① dam  n. 大壩
② lagoon  n. 瀉湖
③ boggy  adj. 泥濘的
④ encroachment  n. 蠶食
Choose the best answers according to the above:
1. Which of the following is the main idea of the text?
A. Venice will not disappear into the sea.
B. Dams are designed to protect Venice.
C. Venice are facing dangers from the tides.
D. Global warming makes Venice worse and worse.
2. If the project comes into use, the waste in the lagoon ______.
A. will be washed away by the tides               B. will be sent to the higher places
C. will be carried away by workers                D. will have to be reused by humans
3. According to the idea of Trevor Davies, the dams won’t be broken because ______.
A. the dams are higher than the buildings in Venice
B. there will be no tides or floods in the future
C. the climate all over the world will soon be cold
D. the storms in the Adriatic will be weaker in the future
4. According to the text, we can infer that Venice ______.
A. has been sinking for hundreds of years
B. may suffer from spring tides and strong winds
C. will be under the sea sooner or later
D. will be a city with dams around except 78 gates

No one can believe that the over 6 300-kilometer long Great Wall might disappear some day.Believe it or not,the Great Wall is being destroyed by people.Less than 20 percent of the Great Wall built in the Ming Dynasty is still perfect,but about 80 percent is in danger.The Great Wall can be called “great” mostly because of its amazing length.But we should realize that the length was made up of one brick at a time.If we do nothing to save the Great Wall,it will become a series of separate wasteland rather than a historic site.
The Great Wall is actually a series of walls built and rebuilt by different dynasties over the past 2 000 years.It began in the rule of China’s first emperor,Qin Shihuang of the Qin Dynasty (221 BC～206 BC),and lasted into the Ming Dynasty.The parts built before the Ming Dynasty have nearly disappeared.People are familiar with sections such as Badaling in Beijing and Jiayuguan Pass in Gansu because they have been open to tourists for many years.But those sections far away from the public eyes have been almost forgotten.
Few local people knew the 3-meter-high walls made of earth and stones beside them are part of the Great Wall.The lack of knowledge is considered as one of the main reasons behind human.
The bricks on the Great Wall are carried off by countryside people to build their houses,sheep corral(畜欄) and pigsties(豬圈).Some were taken away to build roads.Bricks carved with people’s names are put away as remembrance.Rubbish is spread over the battlements(城垛).The bricks can be sold for 15 yuan per tractor load.Those who destroyed and are destroying the Great Wall know its name,but are not clear about its cultural meaning.It will take a long time to let them know this.The local farmers not only carried off the body of the Wall but dug out the entire base.
It is necessary to protect the Great Wall.First of all,the officials should be aware of theimportance of the Great Wall.Young Chinese should know more about the nation’s great civilization (文明)and learn to love it.
小題1:The main reason for which the Great Wall can be called“great”is__________.
A．it was made by brickB．it was very wide
C．it was very longD．it had a long history
小題2:Why does the author say the Great Wall might disappear?
A．It is useless from now on.B．It will be replaced by a new one.
C．Some parts of it are being destroyed.D．It’s too old to be used again.
小題3:The underlined part “those sections far away from the public eyes” refers to the parts of the Great Wall__________.
A．that are too difficult to understandB．nobody can watch
C．that are too far to been seenD．that are not well known to the public
小題4:What’s the main reason of the Great Wall’s being destroyed?
A．The local people are short of culture knowledge.
B．The local people need bricks and stones to build houses.
C．The local people think that the Great Wall is not important.
D．The local people are against the government.

Every human being has a unique① arrangement of the skin on his fingers and this arrangement is unchangeable. Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children, though nobody knows why this is the case.
The ridge structure on a person’s fingers does not change with growth and is not affected by surface injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new one, which bears a reproduction of the original② pattern. It is only when the inner skin is injured that the arrangement will be destroyed. Some criminals make use of this fact to remove their own finger-prints but this is a dangerous and rare step to take.
Finger-prints can be made very easily with printer’s ink. They can by recorded easily. With special methods, identification③ can be achieved successfully within a short time. Because of the simplicity and economy of this system, finger-prints have often been used as a method of solving criminal case. A suspected man may deny a charge but this may be in vain. His finger-prints can prove who he is even if his appearance has been changed by age or accident.
When a suspect leaves finger-prints behind at the scene of a crime, they are difficult to detect with the naked eye. Special techniques are used to “develop” them. Some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained.
Notes:
①    unique  adj. 唯一的，獨(dú)特的
②    original  adj. 最初的，原始的
③    identification  n. 辯認(rèn)，鑒定

Thinking
·Some scientists claim that we humans are the only living things that are conscious(有意識的)—we alone are aware that we are thinking.
·No one knows how consciousness works—it is one of science’s last great mysteries.
·All your thoughts take place in the cerebrum(大腦皮質(zhì)),which is at the top of your brain,and different kinds of thought are linked to different areas,called association areas.
·Each half of the cerebrum has four rounded ends called lobes(腦葉)—two at the front(frontal and temporal lobes)and two at the back(occipital and parietal lobes).
·The frontal lobe is linked to your personality and it is where you have your bright ideas.
·The temporal lobe is where you hear and understand what people say to you.

Directions: Read the following passage. Answer the questions according to the information given in the passage and the required words limit. Write your answers on your answer sheet.
A political scientist from Indiana University whose work exploring how people come together to preserve their collective resources may provide important clues in the fight against climate change has become the first woman to win the Nobel prize for economics.
Elinor Ostrom, 76, shares 2009 Nobel prize with fellow American academic Oliver Williamson, 77. The Royal Swedish Academy of Sciences announced to the world the pair had been chosen to win the 40th prize in economic sciences.
For Ostrom, the award came, as a "big surprise". To rise to the peak of her area of learning has been a big journey, as she has had to struggle against her own weaknesses and the barriers of the system. At school in Los Angeles, she suffered from stuttering. She also faced the barriers common to most women of her generation entering the sciences --- she was discouraged from taking a PhD when she applied for graduate school.
Her field of study has been striking for how cross-disciplinary it is. Early on she gained a reputation for bringing economics, political science and sociology together.
What interests her is how common property can be managed successfully through groups in society. The findings of her research have been striking, as the Nobel committee pointed out, because they have challenged the traditional assumption that common property is poorly managed unless it is either controlled by government or privatized. She has shown how different individuals can band together and form collectives that protect the resource at hand.
“A lot of people are waiting for more international co-operation to solve global warming.” Ostrom said , “It is important that there is international agreement, but we can be taking steps at family level, community level, civic and national level … There are many steps that can be taken. That will not solve it on their own but continuously will make a big difference.”
81. How did Ostrom feel when she got the prize?  (not more than 3 words)
82. What does “cross-disciplinary” mean according to the passage?  (not more than 9 words)
83. Why was Ostrom advised not to take a PhD when she applied for graduate school?  (not more than 9 words)
84. Why was Ostrom awarded the Nobel prize for economics?  (not more than 16 words)

A desert is a beautiful land of silence and space. The sun shines, the wind blows, and time and space seem endless. Nothing is soft. The sand and rocks are hard, and many of the plants even have hard needles instead of leaves.
The size and location(分布) of the world’s deserts are always changing. Over millions of years, as climates change and mountains rise, new dry and wet areas develop. But within the last 100 yeas, deserts have been growing at a frightening speed. This is partly because of natural changes, but the greatest makers are humans.
Humans can make deserts, but humans can also prevent their growth. Algeria Mauritania is planting a similar wall around Nouakchott, the capital. Iran puts a thin covering of petroleum(石油) on sandy areas and plants trees. The oil keeps the water and small trees in the land, and men on motorcycles(摩托車) keep the sheep and goats away. The USSR and India are building long canals to bring water to desert areas.
小題1:In this passage, “needles” refers to _______.
A．small, thin pieces of steel.
B．long, thin pieces of branches.
C．small pointed growth on the stem(莖) of a plant.
D．small, thin pieces of sticks.

As we know, it is very important that a firm should pay attention to the training of its staff as there exist many weak points in its various departments. Staff training must have a purpose, which is defined when a firm considers its training needs, which are in turn based on job descriptions and job specifications(規(guī)范).
A job description should give details of the performance that is required for a particular job, and a job specification should give information about the behaviour, knowledge and skills that are expected of an employee who works in the position. When all of this has been collected, it is possible to make a training specification. This specifies(詳細(xì)說明) that the training department must teach for the successful performance of the job, and also the best methods to use in the training period.
There are many different training methods, and there are advantages and disadvantages in all of them. Successful training performances depend on an understanding of the difference between learning about skills and training in using them. It is frequently said that learning about skills takes place “off the job” in classroom, but training in using these skills takes place “on the job,” by means of such activities as practice in the workshop.
It’s always difficult to evaluate the costs of a training programme. The success of such a programme depends not only on the methods used but also on the quality of the staff who do the training. A company can often check savings in time and cost by examining the work performed by the workers and technicians who have completed a training programme. The evaluation of management training is much more complex than that.
小題1:     The writer mainly wants to tell us_____by the passage.
A． Why firms should pay attention to staff training
B． Staff training must have a purpose
C． Purposes and methods are most important in staff training
D． How to evaluate a training programme
小題2:A training specification specifies_____
A． the training contents and methods
B． the cost and savings of the programme
C． the performance required for a certain job
D． the behaviour, knowledge and skills expected of an employee
小題3:To be successful in training programmes, we must understand the difference between_____
A． the purposes and the methods
B． job description and job specification
C． what is taught and how it is taught
D． learning about skills and training in using them

“Seven out of ten people have tried to learn a language at some point in their life and most wish they could speak one more fluently,” a survey found. “And nine out of ten people want their children to learn foreign languages at primary school,” said the poll for the OCR Examing Board (牛津劍橋皇家考試委員會(huì)).Languages are no longer compulsory(義務(wù)的)for pupils aged 14 and over. But the government wants all primary school pupils in England to learn a language by the end of the decade.
A survey of 1000 people was carried out, which is organised by the National Centre of Language .The study suggested people in London were the most likely(78%) to have studied another language, Scots were next at 74%, followed by the northeast of England (71%).In the west of England, more than six in ten have knowledge of another language.
Barrie Hunt from OCR said, “People are often very negative about Britain，s grasp of foreign languages but in reality the number of people who can speak a second language is impressive. The great joke is that many of these people will have no formal qualification to show their family, friends and employers what they can do. Whether they are fluent or just able to hold a short conversation in another language is unknown.”
He said OCR had set a new language scheme called Asset Languages to encourage people of all ages to learn languages in bite-sized amounts and get a qualification.
The scheme also provides assessment for community languages spoken at home, such as Chinese, Urdu and Punjabi.
Isabella Moore from the National Centre of Languages said, “Employers want evidence of good communication skills, confidence and outward-looking attitudes, so a language qualification is an important addition to anyone，s resume.”
小題1:It can be inferred that___________________________ .
A．foreign language study is popular in UK
B．foreign language study is a must for people of all ages
C．it is especially easy for British people to study foreign languages
D．students of over 14 no longer study foreign languages
小題2:Which of the following has the most to have studied a foreign language?
A．People from Scotland.B．People from the northeast of England.
C．People in London.D．People from the west of England.
小題3: Which statement is true according to the text?
A．A language qualification is the only evidence of a high-quality employee.
B．Speaking foreign languages is the most important skill required in employment among all.
C．A language qualification is very difficult to get in UK.
D．Many people in UK don，t have a qualification although they can speak foreign languages.
小題4: What’s the best title for the text?
A．An Interesting SurveyB．UK Loves After All
C．Language Teaching in UKD．Better to Get a Language Qualification
