Humans are often thought to be insensitive smellers compared with animals, but this is largely because,【C1】_animals

26、, we stand upright. This means that our noses are【C2 】_to perceiving those smells which float through the air, missing the majority of smells which stick to surfaces. In fact, though, we are extremely sensitive to smells, even if we do not generally realize it. Our noses are capable of 【C3 】_human s

27、mells even when these are【C4】_to far below one part in one million. Strangely, some people find that they can smell one type of flower but not another, whereas others are sensitive to the smells of both flowers. This may be because some people do not have the genes necessary to generate【C5】_smell re

28、ceptors in the nose. These receptors are the cells which sense smells and send【C6】_to the brain. However, it has been found that even people insensitive to a certain smell at first can suddenly become sensitive to it when【C7】_to it often enough. The explanation for insensitivity to smell seems to be

29、 that brain finds it inefficient to keep all smell receptors working all the time but can【C8】_new receptors if necessary. This may also explain why we are not usually sensitive to our own smells we simply do not need to be. We are not【C9】_of the usual smell of our own house but we notice new smells

30、when we visit someone elses. The brain finds it best to keep smell receptors【C10】_for unfamiliar and emergency signals such as the smell of smoke, which might indicate the danger of fire.51 【C1 】（A）above（B） unlike（C） excluding（D）besides52 【C2 】（A）limited（B） committed（C） dedicated（D）confined53 【C3 】（

32、igger（D）create59 【C9 】（A）sure（B） sick（C） aware（D）tired60 【C10 】（A）available（B） reliable（C） identifiable（D）suitable六、Part Reading Comprehension60 When a heart-lung machine was invented that could take over the job of the heart, put oxygen into the blood and keep the circulation going during surgery,

33、surgeons could stop the heart while they were cutting and suturing. Recently, in certain cases, some surgeons have begun operating without the pump while the heart continues to beat.“The benefits of off-pump surgery are tremendous for patients who meet the criteria for this procedure,“ said Dr. Jim

34、Zellner with the Alliance of Cardiac, Thoracic and Vascular Surgeons. “There is less need for blood products, less chance of complications during and after surgery, earlier recovery and earlier return to regular activity.“Seawood Murray felt he was led by God to find Dr. Zellner and Memorial Hospita

35、l and to have off-pump surgery. A veteran of the United States Navy as a nuclear weapons security officer and commanding officer of a mine assembly group for more than 31 years, Seawood has never complained about stress or pain. He saw three tours of duty off the coast of Vietnam. However, after suf

36、fering from chest pain for almost a year and being misdiagnosed with chronic heartburn, Seawood knew something was seriously wrong. At the Veterans hospital in Murfreesboro, he learned he had heart disease and was told to come back in six weeks.“I didnt want to wait that long and asked for a referra

37、l to The Chattanooga Heart Institute,“ Seawood said. “Dr. Noel Hunt found that 40% of my heart was not getting the amount of blood it needed to operate properly.“ Four days later, Seawood was undergoing off-pump triple bypass surgery at Memorial Hospital under the hand of Dr. Zellner.“I was sitting

38、up that evening, walking around the second day and feeling good enough to go home the third day, but I stayed till the fourth morning,“ Seawood said. “Two others who had on-pump bypass surgery the same day I had mine off-pump were barely walking when I left.“61 How do surgeons usually operate on a h

39、eart-attacker according to the passage?（A）They operate without a pump.（B） They operate with a heart-lung machine.（C） They operate by stopping the heart.（D）They operate with nothing but cutting and suturing.62 Which of the following statements is NOT the benefit of off-pump surgery?（A）The heart-attac

40、k patients will be recovered in one day.（B） There are fewer chances for heart-attack patients to suffer from other new diseases during the course of hear attack.（C） Off-pump surgery needs fewer blood products.（D）The heart-attack patients will be well again earlier.63 Whats wrong with Seawood Murray?

41、（A）He suffered from chronic heartburn.（B） He suffered from heart attack.（C） He had three tours of duty off the coast of Vietnam.（D）His heart couldnt get blood it needed to operate.64 What did Dr. Zellner do for Seawood Murrays disease?（A）Dr. Zellner gave him a surgery with a heart-lung machine.（B） D

42、r. Zellner diagnosed his disease as chronic heartburn.（C） Dr. Zellner gave him an off-pump triple bypass surgery.（D）Dr. Zellner referred him to another hospital.65 What can we learn from the last paragraph?（A）Seawood Murray could hardly walk four days after the surgery.（B） Seawood Murray got recover

43、ed more slowly than other patients.（C） Seawood Murray felt well and went home the third day after the surgery.（D）Seawood Murray went home the fourth day after the surgery.65 The brain is organized into different regions, each responsible for different functions, and in humans this organization is ve

44、ry marked. The largest parts of the brain are the cerebral hemispheres, which occupy most of the interior of the skull. They are layered structures, the most complex being the outer layer, known as the cerebral cortex, where the nerve cells are extremely densely packed to allow great interconnectivi

45、ty. Its function is not fully understood, but we can get some indication of its purpose from studies of animals that have had it removed. A dog, for example, can still move in a coordinated manner, will eat and sleep, and even bark if it is disturbed. However, it also becomes blind and loses its sen

46、se of smell-more significantly, perhaps, it loses all interest in its environment, not responding to people or to its name, nor to other dogs, even of the opposite sex. It also loses all ability to learn. In effect, it loses the characteristics that we generally refer to as indicating intelligence-a

47、wareness, interest and interaction with an environment, and an ability to adapt and learn. Thus the cerebral cortex seems to be the seat of the higher order functions of the brain, and the core of intelligence.The cerebral cortex has been the subject of investigation by researchers for many years, a

48、nd is slowly revealing its secrets. It demonstrates a localization of functions, in that different areas of the cortex fulfill different functions, such as motion control, hearing, and vision. The visual part of the cortex is especially interesting. In the visual cortex, electrical stimulation of th

49、e cells can produce the sensation of light, and detailed analysis has shown that specific layers of neurons are sensitive to particular orientations of input stimuli, so that one layer responds maximally to horizontal lines, while another responds to vertical ones. Although much of this structure is genetically pre-determined, the orientation-specific layout of the cells appears to be learnt at an early stage. Animals brought up in an environment of purely horizo
