7．Since the earliest civilizations，people have controlled rivers to meet society's demands．Today，rivers are controlled for many reasons，primarily to maintain reliable water supplies for daily，agricultural and industrial needs，for power generation，for navigation （航行），and to prevent flooding．
River control is achieved by channelization，a term that covers a range of river engineering works，including widening，deepening，straightening and stabilization of banks，and by the construction of dams．
An important period of channelization took place in Europe during the l9'th century，when many large rivers were straightened and their beds deepened．One of the most dramatically changed was the Tisza River，a branch of the Danube that flows through Hungary．The controlling of the Tisza，designed to reduce flooding and make land for agriculture，included cutting off more than 100 meanders （河曲），shortening the river's length by nearly 400kilometers．
One of the most common ways in which people control rivers is by damming them．The past 50years or so has seen an increase in dam construction worldwide，and at the beginning of the 21^st century，there were about 800，000dams globally，some towering more than 200meters in height．
Despite their successes，many dams also cause significant environmental changes that prove harmful．Some particularly deep reservoirs （水库） can bring about earthquakes due to the stress on their bottom rocks caused by huge volumes of water．Downstream of a reservoir，the river is certainly influenced in many ways：water volume，speed and quality are all affected，leading to changes in the landscape and among plants and animals．

3．The pound new Library of Birmingham（LoB）will be the most visible sign of the way the city is accepting the digitalization（数字化）of everyday life．
Set to open in 2013，the£188m LoB is already beginning to take shape next to the Birmingham Repertory Theatre，with which it will share some equipment．
As digital media（媒介）is important to its idea，the project is already providing chances for some of the many small new local companies working at the new technologies．
Brian Gambles，the LoB project director，says a it is about giving people the right tools for learning："The aim is to mix the physical with the digital．b Providing 24-hour services which can be used through many different ways．It is important to enable us to reach more people，more effectively．"
The digital library will，he says，be as important as the physical one，allowing the distant use of the services，making sure that it is never closed to the public．
Even before the LoB is complete，the public has been able to go online to visit the Virtual（虚拟的）LoB，designed by Baden，the Birmingham virtual worlds specialists．Not only have the public been able to learn about LoB，but the virtual one has also enabled those working on the LoB to understand the building and how it will work before it even opens．
Two other small Birmingham-based digital companies are working on the LoB projects．Substrat，a digital design company，is developing what it calls an"enlarged reality"project．It is about the use of an exciting smart phone，an important part of LoB the which is the early stages of development．And The People's Archive is an online library of figures of the city being built content company in Cahoots，in which users will be encouraged to add to and comment on the material．Gambles says："Technology will enable us to make the library's and services open to citizens as sever before．"

1．D
Since the 1970s，scientists have been searching for ways to link the brain with computers．Brain-computer interface （BCI） technology could help people with disabilities send commands to machines．
Recently，two researchers，Jose Milan and Michele Tavella from the Federal Polytechnic school in Lausanne，Switzerland，demonstrated（展示）a small robotic wheelchair directed by a person's thoughts．
In the laboratory，Tavella operated the wheelchair just by thinking about moving his left or right band．He could even talk as he watched the vehicle and guided it with his thoughts．
"Our brain has billions of nerve ceils．These send signals through the spinal cord （脊髓）to the muscles to give us the ability to move．But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles，"Tavella says．"Our system allows disabled people to communicate with external world and also to control devices．"
The researchers designed a special cap for the user．This head cover picks up the signals from the scalp（头皮） and sends them to a computer．The computer interprets the signals and commands the motorized wheelchair．The wheelchair also has two cameras that identify objects in its path．They help the computer react to commands from the brain．
Prof．Milan，the team leader，says scientists keep improving the computer software that interprets brain signals and turns them into simple commands．"The practical possibilities that BCI technology offers to disabled people can be grouped in two categories：communication，and controlling devices．One example is this wheelchair．"
He says his team has set two goals．One is testing with real patients，so as to prove that this is a technology they can benefit from．And the other is to guarantee that they can use the technology over long periods of time．
71．BCI is a technology that canB．
A．help to update computer systems      B．link the human brain with computers
C．help the disabled to recover           D．control a person's thoughts
72．How did Tavella operate the wheelchair in the laboratory？D
A．By controlling his muscles．B．By talking to the machine．C．By moving his hand．D．By using his mind．
73．Which of the following shows the path of the signals described in Paragraph 5？C
A．scalp→computer→cap→wheelchair    B．computer→cap→scalp→wheelchair
C．scalp→cap→computer→wheelchair    D．cap→computer→scalp→wheelchair
74．The team will test with real patients toB．
A．make profits from them             B．prove the technology useful to them
C．make them live longer               D．learn about their physical condition
75．Which of the following would be the best title for the text？C
A．Switzerland，the BCI Research Center
B．New Findings About How the Human Brain Works
C．BCI Could Mean More Freedom for the Disable
D．Robotic Vehicles Could Help to Cure Brain Injuries．

8．Plants are flowering faster than scientists predicted（预测）in reaction to climate change，which could have long damaging effects on food chains and ecosystems．
Global warming is having a great effect on hundreds of plant and animal species around the world，changing some living patterns，scientists say．
Increased carbon dioxide（CO2）in the air from burning coal and oil can have an effect on how plants produce oxygen，while higher temperatures and changeable rainfall patterns can change their patterns of growth．
"Predicting species'reaction to climate change is a major challenge in ecology，"said the researches of several U．S．universities．They said plants had been the key object of study because their reaction to climate change could have an effect on food chains and ecosystem services．
The study，published on the Nature website，uses the findings from plant life cycle studies and experiments across four continents and 1，634species．It found that some experiments had underestimated（低估）the speed of flowering by 8.5times and leafing by 4times．
"Across all species，the experiments under-predicted the speed of the advance-for both leafing and flowering-that results from temperature increases，"the study said．
The design of future experiments may need to be improved to better predict how plants will react to climate change，it said．
Plants are necessary for life on the Earth．They are the base of the food chain，using photosynthesis（光合作用）to produce sugar from carbon dioxide and water．They let out oxygen which is needed by nearly every organism on the planet．
Scientists believe the world's average temperature has risen by about 0.8℃since 1900，and nearly 0.2℃every ten years since 1979．
So far，efforts to cut emissions（排放）of planet-warming greenhouse gases are not seen as enough to prevent the Earth heating up beyond 2℃this century-a point scientists say will bring the danger of a changeable climate in which weather extremes are common，leading to drought，floods，crop failures and rising sea levels．

57．What is the key information the author wants to give in Paragraph 1？B．
A．Plants'reaction to weather could have damaging effects on ecosystem．
B．The increasing speed of flowering is beyond scientists'expectation．
C．Climate change leads to the change of food production patterns．
D．Food chains have been seriously damaged because of weather．
58．We can learn from the study published on the Nature website thatC．
A．plants'flowering is 8.5times faster than leafing
B．there are 1，634plant species on the four continents
C．scientists should improve the design of the experiments

A．they can prove the climate change clearly
B．they are very important in the food chains
C．they play a leading role in reducing global warming
D．they are growing and flowering much faster than before
