5．Researchers in the US say they might have discovered how to fight against and even reverse some processes of ageing，at least in mice．Injecting the blood of young mice into the older ones improved their brainpower，a study found．Scientists at Stanford University plan to carry out trials in people in the hope that new treatments for dementia（痴呆症） can be developed．
"There are factors present in blood from young mice that can recharge an old mouse's brain so that it functions more like a younger one，"says Dr．Tony from Stanford University School of medicine．In the study published in Nature Medicine，mice aged 18months were given injections of the blood taken from mice aged 3months．The injected mice performed better on memory tests than mice of the same age that had not been given the blood．Dr．Tony said it was not known whether the same was true of humans，but a trial was planned．
A research center in UK said the treatment restored certain aspects of learning and memory in mice，but was of unknown importance to humans．The research，while very interesting，did not test the type of brain damage that was seen in dementia，which is not a necessary consequence of ageing．
Meanwhile，two similar studies by a separate team have thrown more light on how young blood may benefit the old，in mice at least．A substance in the blood of mice previously shown to have an anti-ageing effect on heart muscle also improved brain cells，according to a Harvard team．The research，published in Science，found the blood factors encouraged the growth of brain cells in old mice，and restored their sense of smell．The same chemical also improved muscle power of aged mice，the researchers found．
29．The underlined word in paragraph 1probably meansA．
A．change B．destroy C．speed D．increase
30．Scientists in the US will test the discovery in humans with the aim ofD．
A．proving the possibility to live longer．
B．showing the importance of scientific research．
C．publishing the study in Nature Medicine．
D．treating an age-related disease successfully．
31．According to the studies，the blood from young mice benefits the old in certain ways except inC．
A．memory B．muscle power C．fur color D．brain cells
32．What's the author's attitude to the anti-ageing studies？B
A．supportive B．objective C．negative D．doubtful． 试题答案
分析 本文是科普类阅读，讲述的是通过在老鼠身上实验发现通过注射年轻老鼠的血液可以改善年老的老鼠的一些状况，将有助于老年痴呆治疗的研究．
解答 29-32 ADCB
29．A 考查细节理解题．根据第一段提到Researchers in the US say they might have discovered how to fight against and even reverse some processes of ageing，at least in mice．Injecting the blood of young mice into the older ones improved their brainpower，a study found．美国一项研究说，他们可能发生了如何对抗和颠倒年龄的过程，在年老的老鼠身上注射年轻老鼠的血液，提高他们大脑的活力，故选A项．
30．D 考查细节理解题．根据第一段提到Scientists at Stanford University plan to carry out trials in people in the hope that new treatments for dementia（痴呆症） can be developed斯坦福大学的科学家计划进行这些实验目的是发现治疗痴呆症的治疗方案，故选D项．
31．C 考查细节理解题．根据倒数第二段提到A research center in UK said the treatment restored certain aspects of learning and memory in mice有助于学习记忆的方面再根据最后一段提到The research，published in Science，found the blood factors encouraged the growth of brain cells in old mice，促进年老的老鼠的脑细胞的生长，故没有提到C 项．
32．B 考查推理判断题．根据倒数第二段提到The research，while very interesting，did not test the type of brain damage that was seen in dementia，which is not a necessary consequence of ageing这个研究虽然很有趣，但没有检出大脑在痴呆坏掉的细胞，这不是变老的必然结果，可见作者持有客观的态度，故选B项．
点评 考察学生的细节理解和推理判断能力，做细节理解题时一定要找到文章中的原句，和题干进行比较，再做出正确的选择．在做推理判断题不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理判断．
Concepts from science and nature are filled with our language’s common phrases , idioms and spoken expressions. The unbelieving expression “Well, I’ll be a monkey’s uncle” has its origin in bitter disbelief over Darwin’s writings on evolution. These colourful expressions bring spice(趣味) to our language.
Yet certain well-used phrases from science are just plain wrong! Some are obvious, yet we use them anyhow. For example, a person who acutely shakes her head and says “ A watched pot never boils” while you are waiting second after tiring second for test results to arrive or job offers to come in knows that if she sat down and watched a pot containing water on a stove over high heat for long enough, the water will eventually boil.
However, a few phrases have less obvious scientific inaccuracies. Here are a few for you to consider.
Once in a blue moon: This poetic phrase refers to something that occurs extremely rarely. A blue moon is the term commonly used for a second full moon that occasionally appears in a single month of our solar-based calendars. The problem with the phrase, however, is that blue moons are not so rare. They happen every few years at least, and can even happen within months of each other when the 29.5-day lunar cycle puts the full moon at the beginning of any month but February. The usage of “blue moon” as the second full moon in a month dates back to a 1937 Marine Farmer’s Almanac . But before that, blue moons meant something slightly different. Typically, 12 full moons occur from winter solstice to the next winter solstice, but occasionally a fourth full moon in a season could be observed . In such a case, one of the four full moons in that season was known as “blue”
Where there’s smoke, there’s fire: The phrase means that if something looks wrong, it likely is wrong. But let’s step back. Do you always have to have fire if you see smoke? Answering that first requires defining ‘fire” , Merriam—Webster’s first definition of fire is “ the phenomenon of combustion manifested in light, flame and heat”. Combustion is the chemical reaction that occurs when fuel is burned in the presence of oxygen---denying a fire any of these three things will stop the fire; attempting to start a fire without any one of the three things will be impossible. In complete combustion---what occurs when you light a gas stove--- the fire produces no smoke. However, when most materials are burned, they have incomplete combustion, which means that the fire isn’t able to completely burn all of the fuel . Smoke, then, can be considered to be a product of pyrolysis (高温分解) rather than of fire itself. You’re probably thinking---so what? To get the smoke, a fire needed to be present at some point, right? Not always.
Diamonds are forever: Thanks to the DeBeers slogan , decorating your honey’s neck, wrists and fingers with diamonds means true and timeless love. Of course, no object that you can hold in your hand can last forever. But diamonds have a special reason for being incapable of timelessness. Without the extreme pressures of the deep Earth where they formed, a diamond will slowly turn back into graphite(石墨), which is why the older a diamond is, the more inclusions it’s likely to have.
What common phrases push your buttons when viewed under the microscope of science? Are you curious about the hidden knowledge of some “ big” phrases ? Or perhaps you have the ability to uncover the secret of some unscientific phrases? Let us know!
