Research on the human brain has been attracting the attention of more and more scientists in recent years, just like the booming hi-tech industry. One of the latest research topics is how to change the human brain or combine the computer and the human brain, i．e．, to transplant a chip into human brain．This idea may make everyone's dream come true．If we compare a human brain to a hard disc, what the scientists are doing is to enlarge the capacity of the hard disc．For the time being, there are some difficulties in such transplant experiments, but scientists never give up．
Experiments were started on animals．In 1996, a transplant experiment performed at the Defense and Military Physiology Research Institute in the U．S．turned a bear into a dolphin．
The dolphin was named Ted, and the bear was named Tallin．Using the most advanced technology, deep and detailed studies were made of the swimming action memory area in Ted's brain by the scientists．They got a lot of useful information．The information was saved into a button-sized chip, which was then transplanted into the action memory area in Tallin's brain．The information saved on the chip was released by means of electric power．
Recently, another memory transplant was performed at the Motor Nerve Research Institute of the University of California．The comprehensive memory transplanted in the experiment included actions, moods, logic, words, images, etc. The experiment involved an entire transplant of the memory area. This was the largest such experiment done so far.
The transplant was performed from a dog named “Genius” to a dog named “Idiot”．“Genius” could understand and follow up to 100 gestures and orders made by its master．It was a real genius．“Idiot” was the younger brother of “Genius”．It had no contact with people at all since its birth．It became an animal with nothing in its brain, without any memory．
The operation was a complete success．When the two dogs woke up, “Idiot” had grasped all the abilities “Genius” possessed; it was good at memorizing and sensible. It could follow every gesture and any command given by its master．But “Genius” gave no response to its master, and in fact did not recognize him at all．
47．The purpose of the experiment is____.
A．to combine the computer and the human brain
B．to make bear swim
C．to make some stupid dog turn clever
D．to enlarge the capacity of human brain
48．Which of the following statements is TRUE?
A．The scientists transferred a button-sized chip which useful information in Tallin’s brain.
B．The first comprehensive memory transplant was performed at the Motor Nerve Research University.
C．The second experiment wasn’t an entire transplant of the memory area.
D．The Idiot was an animal with memory before brain experiment
49．What does the underlined word “success” refer to?
A．The two dogs woke up.
B．They were both good at memorizing.
C．The Idiot grasped all the abilities of Genius.
D．The Genius grasped all the abilities of Idiot.
50．According to the text, we can infer .
A．a person can know more after the experiment.
B．a bear can swim after being transferred a chip with related useful information
C．a dog can become clever after entire transplant of the memory area
D．it is really good for animals to have been involved in the transplant experiment

Beijing plans to build huge free or low-cost parking lots beyond the Fourth and Fifth Ring Roads to encourage more car owners to take buses or subways to the downtown area．
The plan is just one of the many measures the city plans to take to reduce its traffic jams．Low or no parking fees would be used as economic leverage(杠杆作用) to reduce growing parking demands from urban areas．
Car owners living in the suburbs will be encouraged to park their cars beyond the Fourth and Fifth Ring Roads and take buses or subways to the downtown area．Statistics show that nearly one quarter of the city’s traffic flow is concentrated in the 62-square-kilometer downtown area within the Second Ring Road, which makes up only 12 percent of the city’s total area．
The Beijing Traffic Management Bureau receives between 400 and 500 calls reporting traffic jams every day and more than 90 percent of the roads are filled to capacity during rush hours every morning and evening．Part of the problem is the lack of easy links between bus routes, subways and cars．
According to the communication commission, half of the city’s investment in transportation will go towards public transit（公共交通） construction in the next few years, making a jump from the current only 20 per cent．Moreover, Beijing plans to change its layout （布局） by building new city centers, such as at Yizhuang, Tongzhou, Shunyi and Changping, in a bid to reduce the traffic flow to the downtown．
The current layout of Beijing-expanded ring roads around the same center of the Forbidden City, is seen as the root cause of the endless traffic jams．The downtown area is crowded with three business centers and one financial center, as well as nearly 400 government organs and institutions．
Traffic experts say building more urban centers around Beijing may reduce the number of residents living in the suburbs and traveling long distances to work downtown every day, thus reducing traffic flow．
40．In the coming years, if a man beyond the Fourth Ring Road goes to work in the downtown of Beijing, he is encouraged to _________．
A．take buses or subways B．take a taxi
C．drive the car quickly D．park his car in a place which asks for no fees
41．According to this passage, when more and more people drive to work in rush hour in Beijing, it is likely to _______．
A．save time B．cause traffic jams
C．cause traffic accidents D．reduce air pollution
42．The aim in building new city centers is to ________．
A．make it convenient for people to go shopping
B．develop its local resources
C．reduce the traffic flow to the downtown
D．solve the problem of more laid-off workers
43．The passage suggests the author ______．
A．is tired of driving to work
B．finds it costs less to take subways than to drive
C．is for the plan to reduce Beijing’s traffic congestion(拥挤)
D．has benefited a lot by driving to the downtown every day

The damming of river systems in the northwestern United States has had damaging effects on salmon(鲑鱼). In the spring young salmon, called smolts, drift into rivers from smaller streams. They swim with the current downstream heading for the Pacific Ocean. Before the large-scale constructions of dams(水坝), the young salmon used the strong flow from melting snows to get to the sea in between six and twenty days. It is necessary to do this because during these days the smolts’ bodies undergo the physiological changes for adaptation to salt water.
Unfortunately, the current has become very slow due to the construction of numerous dams. Companies operating the dams also intentionally slow the current. They store the water from the melting snow until the winter, when more electric power is needed. The net result is that many of the young fish do not survive the now sixty-day trip to the sea. Consequently, there are fewer adult salmon to migrate(回游) back up the rivers for breeding. When the time comes for the salmon to return, they again face the problem of dams. As fewer adult salmon are able to get back to their cool upstream water, they fail to produce a sufficiently new generation of salmon. This cycle could eventually lead to the extinction of the fish.
Attempts are being made to transport the young salmon down river by boats. However, many scientists think that this artificial method of getting the fish to the sea kills more than it saves. Another suggestion, recently proposed by environmentalists, is to increase the rate of water flow. This would be a partial（部分的） solution to the declining salmon numbers. One method of doing this would call for releasing water from upstream dam. This would speed up the downstream movement of the smolts.
Another method would be to reduce the water level in the dams for a period in the spring when the smolts are migrating downstream. This would also increase the flow rate temporarily without requiring large amounts of water and, thus, enable the young salmon to move downstream faster. Unfortunately, both of these proposals have met with criticism from the power companies, which strongly suggests the uncertain fate of the salmon in the region.

A. The failure of adult salmon to reproduce.
B. The importance of smolts returning upstream.
