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 21st 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 （水庫） 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．

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（頭皮） 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．
