学生安全教育Students safety education Take care of ourselves! Chinese Education Ministry has paid close attention to self-protection education among school students because some knowledge about self-protection may help one survive in case of emergency. In my opinion, no lesson is more important than the one on personal safety. Life is fragile but can be strengthened when one is armed with enough knowledge on how to protect oneself from danger. As middle school students, we should learn some knowledge about safety. Firstly, we should always obey the traffic rules. When we go across the road, we must wait for the green light. When we go to school or go home by bike, we should go along the right side and should not ride at a high speed. Secondly, in order to avoid fire in our dormitory, we should not use any electric device without permission. Thirdly, we should not climb the fence of the school in case that we might hurt ourselves. It is high time that we should be aware of the importance of self-protection. And only with a good sense of self-protection can we live a safe and happy life! 社交习俗Social customs

When a viral infection spread through five genetically identical mice in a row, the virus replicated（复制） faster and became more virulent or severe. But when the infection spread one-by-one through five genetically diverse mice, the virus had trouble adapting and became less virulent. By showing this long-suspected mechanism（机制） holds true within a single species of vertebrate animal, namely, mice, the University of Utah study suggests that increased genetic diversity should be promoted in livestock and in captive-bred species so as to limit their risk of getting deadly infections. "This study showed a surprising rapid and large effect of genetic diversity in mice that dramatically reduced the replication of virus infecting the mice and the severity of disease caused by the virus," says biology professor Wayne Potts. He is senior author of the study published online this month in the British journal Proceedings of the Royal Society B. "There's a reason we are not clones of our mom and dad," says the study's first author, Jason Kubinak, a postdoctoral fellow in biology. "Among other reasons, it's because mechanisms that promote genetic differences between us probably protect us from more severe infectious disease."Indeed, Potts and Kubinak say their study's findings support the "sex-against virulence hypothesis（假设）." It argues that sexual reproduction, which promotes genetic diversity, may have evolved as a way to counter virulence. "The idea is that sexual reproduction produces different genetic makeups in all the kids so they are different than mom's and dad's, and therefore become more difficult to infect," Potts says. "Our study simulates this condition : The inbred mouse example is like an asexual(无性) line because they all have the same genetic makeup . This is one of the first empirical demonstrations of how pathogens（病原体）could make it so that sexual reproduction had great benefits in providing resistance to diseases." Another hypothesis is that sexual reproduction evolved to effectively wipe out many of the harmful genetic mutations（突变）that occur every generation. Kubinak and Potts conducted the research with University of Utah colleagues Douglas Cornwall, a doctoral student in biology, and Fred Adler, a professor of mathematics and biology, along with virologist Kim Hasenkrug, of Rocky Mountain Laboratories, a Hamilton, Montana, lab of the National Institutes of Health. The study was funded by the National Science Foundation and National Institutes of Health. 1.What does the passage mainly tell us? A. Biological study is of great significace . B. Genetic diversity reduces the replication of virus and its virulence C.Sexual and asexual reproduction are different. D. How we can protect endangered species 2. What can we infer from the passage? A.Mice can be infected by virus easily. B. Single gene species might have a high risk of getting deadly infections. C. Asexual reproduction have no benefits. D. Wayne Potts didn’t agree with clone techlonogy. 3. According to the passage, cloning our dad our mom and dad is not advisable, because _____ A. genetic makeups in children are different than mom's and dad's B. clone may cause genetic mutations.

This is likely due largely to the physical changes of our nerves and neurons (神经元). New research suggests 'rapid fire' abilities of the young brain allow us to process more information during youth, causing the days to seem longer earlier in life. However, as we get old, researchers say the older brain takes more time to process information. The new finding put forward by a Duke University researcher was published in a paper in the journal European Review this week According to Adrian Bejan, the J. A Jones Professor of Mechanical Engineering at Duke, the physical changes of our nerves and neurons play, a major role in our perception (知觉) of time as we get old. Over the years these structures become more complex and eventually begin to degrade. "Little babies, for example, move their eyes much more often than adults because they're processing images at a faster rate," Beian says, For older people, this means fewer images are being processed in the same amount of time, causing experiences to seem as though they're happening more quickly. （1）What causes time to fly faster as we get old? A. Changes of our nerves and neurons. B. Information in our brain. C. The electrical signals. D. Rapid fire abilities. （2）What is unavoidable in the process of getting old? A. Longer days. B. Aging brains. C. More images. D. Less experience.（3）Why do the days seem longer earlier in life? A. Young people are more energetic in their life. B. The younger brain takes less time to process information. C. Old people have fewer things to do than young people. D. Little babies move their eyes much more often. （4）What is the best title of the text? A. Nerves and Neurons B. Time Flies Fast C. The Older, the Faster D. The Function of the Brain 【答案】（1）A （2）B （3）B （4）C 【解析】【分析】本文是一篇说明文，介绍了为什么老年人会觉得时间过得较快，主要原因是随着年龄的增长，大脑中神经元的变化让老年人的大脑需要更多的时间来处理接收到

科教科普类 1、Australia leads the world in its number of resident poisonous spiders as well as the strength of their toxicity(毒性). However,of almost 9,800 species most are perfectly harmless and interesting. Spider diversity is broad and many fascinating species occur here that range from the large to the tiny and hardly noticed, and from the dullest black to the strangely shaped. Spiders can be roughly classified according to the strategies(策略) they use for feeding. Spiders which appeared earlier in the evolutionary scale feed by waiting in a cave for food to come along before grabbing it. Following them were spiders which actively wandered looking for food and which caught it by chasing it down. The evolution of flying insects makes spiders evolve ne w ways of catching food which couldn’t be chased and so the earliest air web weavers arose. Most spiders feed on insects and other arthropods but the Whistling Spider feeds on frogs and small birds. The Golden Orb Spider also feeds on small birds. A spider periodically sheds(蜕皮;脱落) its skin so that it can grow. Immature stages are called moults. Each species has a particular number of moults that it will go through before reaching its final adult stage. Usually, once male spiders have mated, they die shortly after. But, even in death, Redback males often serve a purpose. The already pregnant Redback females always kill their lover and, in most cases, also eat them. This provides them with a small reproductive advantage. Allowing spiders to take up places around houses can be beneficial in that they catch other annoying insects such as mosquitoes and flies. Rest assured that while you might see some large spiders, and perhaps even some poisonous ones, a good rule is to look and admire but don't touch any spider you find. Even those without poison could still have a nasty bite. 1.Different families of spiders are identified themselves by ______. A.their physical character B.their ways of getting food C.the strength of their toxicity D.their effect on the environment 2.What are the latest spiders in their evolution process?
