【实战演练练习二十】（05辽宁卷 E篇）
There are two kinds of physical activity which require special training. The first demands exact careful movements of the muscles（肌肉）. This kind of activity must be strictly controlled because even a slight movement in the wrong direction will lead a mistake. To type quickly, for example, a person needs training; the slightest movement of a finger in the wrong direction may cause a spelling mistake. A dancer who has to dance on the point of her shoes or turn around on one foot must be trained for a long period of time before she can sense her own center and balance herself. You may have seen a girl walking on a rope across an empty space, which, too, requires a lot of practice.
The second kind of physical activity needs greater strength or extra effort. Most of us get tired if we try to run half a mile without stopping, but a specially-trained person can do this without much effort. Three years ago, some scientists carried out experiments, which produced meaningful and unexpected results. They wanted to find out whether a certain amount of physical exercise would injure those suffering from heart problems. They selected some male patients and trained them in continuous bicycle riding. They were surprised to find that the harmful effect of given amount of physical effort was actually less on the hearts of these trained patients than on those of the patients who were not similarly trained．This is important because it shows that regular physical exercise enables us to make better use of the oxygen（氧气）we breathe in and that this training, in fact, reduces the amount of work our hearts do. Many tasks which are hard for untrained people are not hard at all for trained people.
72．The first kind of physical activity must be strictly controlled because _________.
A．a mistake in the wrong direction is dangerous to the fingers
B．a wrong movement in a direction will cause no mistakes
C．a movement in the wrong direction will cause a mistake
D．a slight movement of a finger will lead to a mistake
73．What must a dancer do before she can balance herself?
A．She must dance on the point of her shoes.
B．She must receive long-time training.
C．She must turn around on one foot.
D．She must perform again and again.
74．The experiments done by some scientists showed that ________.
A．some male patients were asked to ride bicycles regularly in the experiments
B．the physical exercise had more harmful effect on the hearts of the untrained patients
C．the physical exercise was harmless to the male patients with heart trouble
D．the physical exercise could be helpful for the patients to take in more oxygen
75．What would be the best title for this text?
A．Training Our Bodies B．Physical Activities
C．Movement Training D．Extra Body Effort

"Have you ever been out on a boat and felt it lifted up by a wave? Or have you jumped in the
water and felt the rush of energy as waves came over you?" asked Jamie Taylor of the Wave Energy Group at the University of Edinburgh．"There is certainly a lot of energy in waves," he said．Scientists are working to use that energy to make electricity．Most waves are created when
winds blow across the ocean．"The wind starts out by making little ripples (涟漪) , but if they
keep on blowing, those ripples get bigger and bigger and turn into waves," Taylor saiD．“Waves
are one of nature 's ways of picking up energy and then sending it off on a journey.”
When waves come toward the shore, people can set up dams to block the water and send it
through a large wheel called a turbine (涡轮机) ．The turbine can then power an electrical
generator to produce electricity.
"The resource is huge," said Janet Swain of the World watch Institute．"We will never run out of wave power．" Besides, wave energy does not create the same pollution as other energy sources, such as oil or coal．Oceans cover three-quarters of the Earth's surface - that would make wave power seem ideal for creating energy throughout the world, though there are some weak points yet to overcome．
Swain said that wave power still costs too much money．She also said that its effects on sea animals are still unknown．What is more, wave power could affect fishing and boat traffiC．
Traditional sources of energy like oil and gas may someday run out．"Demand for energy to
power our TVs and computers, drive our cars, and heat and cool our homes is rising rapidly throughout the world," Swain said．In the future when you turn on a light, an ocean wave could be
providing the electricity!
64．The writer uses the two questions at the beginning of the passage to _______.
A．test the readers' knowledge about waves
B．draw the readers' attention to the topic
C．show Jamie Taylor's importance
D．invite the readers to answer them
65．The underlined phrase "picking up" (paragraph 2) is closest in meaning to _______.
A．starting again B．speeding up C．gathering D．improving
