A new eight-kilometer road is under construction that links the port area with motorway system. It is expected to carry 20,000 trucks and cars a day, which greatly reduces the overcrowded traffic in the center of the city. As part of the project, two four-kilometer road tunnels are being built below the central area of the city, one for traffic to the north and the other for the traffic to the south. The two tunnels are about 20 meters below the surface and are 12 meters wide, providing for two lanes of traffic in each direction. 

In the upper part of the tunnel two air-conditioning pipes remove the waste gas of trucks and cars and keep the quality of air inside the tunnel. The lighting is at the top of the tunnel, practically at its highest point. There will also be electric signs at frequent intervals. They show traffic conditions ahead and can be seen clearly by drivers. The wall is made up of four main elements, which include a waterproofing covering and, on the inside of the tunnel, a concrete lining.
Each tunnel is roughly round and the lower part of the tunnel is somewhat flat. The surface of the road lies on the base, which is made of concrete and steel. The drainage system, just below the road surface on one side, removes any extra liquid, particularly water. In the event of fire, the fire main, which is made of steel, pipes water to many fire hydrant stations at regular intervals along the length of the tunnel. The fire main is at the side of the tunnel and at the level of the road surface. Other systems in the tunnel will include emergency phones.
小題1:Each of the tunnels under construction is _____.
A．eight kilometers long and twenty meters wide
B．eight kilometers long and six meters wide
C．four kilometers long and twenty meters wide
D．four kilometers long and six meters wide
小題2:Which part of the tunnel in the diagram is used to pipe out extra water?
A. 1           B. 3            C. 5               D  6 
小題3:Driving in the tunnel, one can know the traffic conditions ahead through______.
A．the lightsB．the electric signs
C．the trucks and the carsD． the emergency phones
小題4:The passage is mainly about _____.
A．the construction of a roadB．the design of a road
C．the construction of two tunnelsD．the design of two tunnels

小題1:D
小題2:C
小題3:B
小題4:D

小題1:細節(jié)推斷題。從第一段“As part of the project, two four-kilometer road tunnels are being built”可知，tunnels長4公里；從“The two tunnels are about 20 metres below the surface and are 12 metres wide”可知，兩個隧道寬12米，因此1個隧道寬6米。
小題2:判斷題。本題問的是“排除多余的誰的管道在隧道的什么部分”。從第三段“The drainage system, just below the road surface on one side, removes any extra liquid, particularly water.”可知排水系統(tǒng)正好在路表面一邊的下方，對照剖面圖，5符合這個位置。
小題3:細節(jié)推斷題。從第二段“There will also be electronic signs at frequent intervals. They show traffic conditions ahead”可知電子告示的作用是顯示交通狀況，因此選B。
小題4:主旨題。文章主要講的是兩個隧道，因此首先排除A、B。文中講到的是隧道的內(nèi)部構(gòu)造，因此C“兩個隧道的建設(shè)”也不對。

"The uniform makes us look like a bunch of clones, especially when we are doing morning exercises in the playground, "said Qing, a Senior 2 from a high school in Shanghai. "But we are not exactly the same from the top to the bottom. The boys wear different sport shoes and girls have different decorations ( 裝飾品 )in their hair. These are the areas where you can express yourself" said Qing.
Although it might be strange for boys to talk about fashion, they do care about what they wear in school, especially shoes, according to Qing.
"Nike and Adidas basketball shoes, although they are still the must for many of my friends ,are becoming out-of-date,” added. He explained, "Since Liu Xiang ran so fast in Athens, running shoes are becoming popular in this autumn."
"Still in fashion are the various baseball caps and American-style T-shirts with random English words printed on them, "said Qing. "The accuracy ( 準確性 )of the written message isn't important. Often, the words are misspelt . Sometimes they do not even make sense “ Qing said with a smile.
Besides sports shoes and T-shirts, styles and colours of school bags are another opportunity for students to express their taste in fashion. Some bags are made more eye-catching by decorating them with small hanging dolls. Other fashionable items are the colourful drink contains which are now popular among girls this semester.
As in China, the new semester in the US also brings new fashion trends: shirts printed with Chinese words, necklaces with Hebrew ( 希伯萊 )or Hindi ( 印度的 )characters, and Brazilian jewelry, are all common in schools in Florida, according to Carmen Domingues, a high school student.

The Baima is a minority group of about 1,400 people. They have lived in Northern Sichuan and Southern Gansu Provinces for centuries. They have long depended on the forests as their main source of income. But since a ban on cutting down forests was introduced in the late 1990s to fight yearly flooding, the villagers have had to look for other means of earning a living.
Several are now in the process of developing a small tourism industry as their lands are rich in forests and natural scenery and are the home of the giant pandas. Xiangshujia, in particular, is becoming a popular bed and breakfast centre for tourists heading to Wanglang to see the giant pandas. Visitors are also starting to take notice of the Baima people themselves.
As our jeep stopped in the courtyard of a house, we were greeted by the village leader Li Qin and young Baima girls dressed in traditional costumes with white feathers in their hair. As we took our places on wooden benches near an open fire, the girls began to sing traditional songs as they served us.
“The number of tourists is growing,” said Li Qin. “We realize that to attract visitors we have to show our culture by offering more traditional singing and dancing and ensuring our houses are built in the traditional way.”
Relations between the Baima people and the reserve were once tense following the ban on cutting down forests. Villagers had to make a new living. They entered the Wanglang Nature Reserve to collect wild mushrooms and herbs (藥草), often at the expense of disturbing the pandas’ habitat. But things greatly improved as villagers started receiving training in how to sell things to tourists.
“Our aim was to deter the villagers, because they often disturbed the pandas’ habitat, and to ensure they could have a long-lasting means of earning a living,” emphasized Chen Youping, director of the Wanglang Nature Reserve. “All the money from the reserve goes back into the community and conservation projects,” said Chen. “We take into consideration first the animals and then tourism.”
小題1:From Paragraph 1 we learn that ________.
A．the Baima has the longest history among all the minority groups in China
B．the Baima people live in most areas of Sichuan and Gansu Provinces
C．forests are the main source of firewood for the Baima people
D．in order to fight floods, the Baima people are forbidden to cut down forests
小題2: We can infer that the Baima girls wore their traditional costumes to greet visitors mainly because _______.
A．they wanted to look more beautiful
B．their leader Li Qin asked them to do so
C．it was a way to show their culture to attract visitors
D．it was necessary before they sang traditional songs
小題3:Which of the following was NOT an effect of the ban on cutting down forests?
A．The Baima people had a tense relationship with the reserve.
B．Villagers had to look for other means of making a living.
C．The pandas’ habitat was often disturbed by villagers.
D．Villagers stopped selling things to tourists.
小題4:The underlined word “deter” in the last paragraph can be replaced by “________”.

  In a recently published book, I came across some exercises with interesting names such as fishbone diagrams, lotus flowers and clustering. As I used these exercises in my classes, I noticed that students were interested. They said more and wrote more. They enjoyed expressing their ideas and sharing them in groups. They were no longer passively waiting for the bell , but actively taking part in the lesson. I find that creativity can act as a way to increase participation and improve fluency.
Creativity has become a popular word in recent years. Scholars in arts, psychology, business, education and science are all working to get a deeper understanding of it. Robert J. Stemberg is a creativity specialist and Yale professor of psychology. He defines creativity as “the ability to produce work that is both new (original) and appropriate(applicable to the situation ) ”. this definition is useful, as we want our students to use language in a new way and to use it correctly and properly. Mot scholars say there are two types of creativity: big “C” creativity and small “c” creativity. Big “C” creativity refers to genius level thinking that results in artistic masterpieces and scientific breakthroughs. Small “c” creativity refers to everyday level thinking that can be used in any situation our emphasis is on the latter. While it goes without saying that any of our students could go on to be the next Picasso or Edison, our aim is to help students produce more ideas and use language in a new way.
小題1:The underlined words “waiting for the bell ” in the first paragraph probably means______.
A．longing for a phone callB．hoping to have a bell
C．expecting the end of the classD．waiting to speak in the class
小題2: It can be inferred from the passage that the author thinks the exercises in the book were _____.
A．popularB．usefulC．scientificD．creative
小題3:When you use a familiar word in a new way, you are ________.
A creative in the sense of big “C” creativity.
B. creative in the sense of small “c” creativity..
C. not creative in the sense of big “C” creativity..
D. not creative in the sense of small “c” creativity.
小題4:The main purpose of the passage is to _________.

Directions: Read the following passage. Fill in the numbered blanks by using the information for the passage. Write NO MORE THAN 3 WORDS for each answer.
A Low-Carbon Economy (LCE) refers to an economy which has a minimal emission of greenhouse gas (GHG), namely, carbon dioxide into the biosphere(生物圈). Recently, most of the scientists and the public hold the opinion that the climate is changing because there is such an accumulation of CO2 in the atmosphere due to human activities. The over-concentration of these gases is producing global warming that affects long-term climate, with negative impacts on humanity in the foreseeable future. LCE, therefore, is proposed as a means to avoid catastrophic climate change.
All nations which are considered carbon intensive societies and societies which are heavily populated should become zero-carbon societies and economies. Several of these countries have promised to become 'low carbon' but not entirely zero carbon, and claim that emissions will be cut by 100% by balancing emissions rather than ceasing all emissions.
Nuclear power and the strategies of carbon capture and storage (CCS) have been proposed as the primary means to achieve a LCE while continuing to exploit non-renewable resources. Scientists are afraid, however, whether the spent-nuclear-fuel can be stored, and whether it is secure. Also they are not certain about the costs and time needed to successfully implement CCS worldwide and whether the stored emissions will leak into the biosphere or not. Alternatively, many have proposed renewable energy should be the main basis of a LCE, but, they have their associated problems of high-cost and inefficiency; this is changing, however, since investment and production have been growing significantly in recent times. Furthermore, it has been proposed that to make the transition to an LCE economically attractive we would have to attach a cost (per unit output) to GHGs through means such as emissions trading and/or a carbon tax.
A LCE is aimed to integrate all aspects of itself from its manufacturing, agriculture, transportation to power-generation around technologies that produce energy and materials with little GHG emission and thus around populations, buildings, machines and devices which use those energies and materials efficiently and dispose of or recycle its wastes so as to have a minimal output of GHGs.
Title:        71

We do not know exactly how many whales there are in the sea because we can’t count them. But we believe at the beginning of the eighteenth century there were 105,000 humpback whales and 120,000 right whales. At the beginning of the twentieth century there were 75,000 humpbacks and 80,000 rights.
Since 1900 their numbers have fallen very quickly. Between 1935 and 1950 the number of humpbacks fell from 20,000 to 10,000 and since 1950 the number has fallen to only 6,000. The number of right whales has fallen even faster. In 1935 there were 25,000. The number fell to 6,000 in 1950 and since 1950 the number has fallen to 4,000. Men have always been hunters. Thousands of whales have become victims(犧牲品). It’s time to do something to protect whales.
小題1:Which of the following is true?
A．We know the exact number of whales in the sea.

Electricity, like clean water, is a resource that’s often taken for granted. But last summer, when blackouts struck much of the northeastern US, Ontario and Rome, consumers on two continents were given a painful reminder of just how easily broken electricity supplies can be. The massive disorder stranded (使陷入困境)commuters, stopped freezers, shut down businesses and refocused attention on where most of the planet’s power comes from：oil-and-gas-fired generators and nuclear plants, These sources not only pollute the environment but also make many consumers feel unacceptable health risks.
Companies are trying to offer an alternative, clean energy from renewable resources that’s plentiful and portable. Lifton’s Medis Technologies, as well as companies like Hydrogenics and Nanosys, is tapping into fuel cells and dolor panels to give people power whenever and wherever they want it, free from dependence on local grids(電網(wǎng)).
The search for alternative energy is nothing new, but the current trend of innovators is focusing on the goal of making clean and sustainable power a mainstream commodity. For example, the fuel cell, which produces electricity from the chemical reaction between oxygen and hydrogen, has been around for about 150 years, though its commercial development did not begin until the 1960s and then only as part of NASA spacecraft. Today this technology is coming down to Earth in places like Tokyo; in nine European cities, from Stockholm to Porto, each operating three hydrogen-fuel-cell buses; and in Iceland, which is trying to create the first fuel free hydrogen economy by 2030.
When hydrogen and oxygen molecules(分子)combine, the reaction produces heat and water. Fuel cells use this reaction to generate electricity. With the cell phone and gadget(小機件)market in mind, Medis has developed a fuel cell with cheap components that produces little heat and effortlessly reduces waste water without turning to energy consuming pumps.
小題1:What is the passage mainly about?
A．The future of alternative energy
B．How the fuel cells works
C．People’s search for alternative energy
D．The damage done by the blackout last summer.
小題2:What can we know about the fuel cell?
A．Its commercial use began in the 1960s.
B．Today it’s being used in almost every corner of the world.
C．It has been in widespread used for about 150 years.
D．It supplies electricity to make the combination of oxygen and hydrogen possible.
小題3:Which of the following statements is NOT true according to the passage?
A．Lifton’s Medis Technologies is tapping into fuel cells and solar panels.
B．The fuel cell has been around for about 150 years.
C．The fuel cell’s commercial development did not begin until the 1960s.
D．When hydrogen and oxygen molecules combine, the reaction produces o2 and H2O.
小題4:The underlined word “blackouts” in the 1 st paragraph means_____.
A．power failureB．the delivering of electricity
C．the power of electricityD．power station
