8、iew” talk the next morning. He asked me to speak to the group. After the call, my whole body became feverish and panicky. The time from his call to the next morning seemed like years. The whole night, I could not sleep with many ominous apprehensions in mind. One of them was to call the principal wi

9、th regret and tell him that I could not come. Finally, I gathered some courage. I thought, “If I miss this opportunity, surely the school will never invite me again to any of their programs.” I reached the school in time. Before my turn came, my whole body was trembling. When my turn came and I star

10、ted speaking, my heartbeat increased and my mouth went dry. I wasnt even able to read the written speech properly. I was not aware of where I was standing and what I was reading. That was the day when I realized my biggest weakness, Public Speaking. After my speech, I met with the principal and expl

11、ained what happened to me. He told me that this happens to everyone. Even great speaker, faced the same things when they started. He suggested that I come again next time. Around one month later, I was invited to refer to a topic on Motivation. This time I was feeling comfortable. My speech was not

12、only appreciated by the principal as well as the teachers, because I was able to get my idea across to them. They encouraged and praised my efforts. After delivering successfully, I became more confident. I said to myself, “If I can speak in front of such a learned audience, like the principal who e

13、ducates others, I can now speak in front of others too.” I started delivering lectures in my plan, on various topics like Self Motivation, Personality Development, Personal Excellence, Spoken English and Presentation Skills. This has become a passion for me. I learned that everything is possible if

17、e used a variety of drugs to treat brain disorders including murine versions of Alzheimers disease(阿尔茨海默氏病）and depression. But in people, these same treatments usually fail. And now researchers are beginning to understand why. A detailed comparison of the cell types in mouse and human brain tissue f

18、ound subtle but important differences that could affect the response to many drugs, a team reported on Wednesday.“If you want to develop a drug that targets a specific receptor in a specific disease, then these differences really matter,” says Christof Koch, an author of the study and chief scientis

19、t and president of the Allen Institute for Brain Science in Seattle.One key difference involved genes that cause a cell to respond to the chemical messenger serotonin (血淸素), says Ed Lein, a study author and investigator at the institute. “Theyre expressed in both mouse and human，but theyre not in th

20、e same types of cells,” Lein says.Now, researchers have a way to make sure the types of cells involved in a particular disease work the same way in people as in an animal model, Koch says.“The technology finally caught up with what weve been needing to do for probably over 40 years, says Tomasz Nowa

21、kowski, an assistant professor of anatomy at the University of California, San Francisco who co-wrote an editorial that accompanied the study.To compare mouse and human brain cells, researchers first analyzed sixteen thousand human brain cells taken from the middle temporal gyms, a part of the corte

22、x(大脑皮层), the brains outermost layer. Then they looked at cells taken from the same area of a mouse brain.“In one sense, they are remarkably similar,” Koch says, noting that both mice and human had about 100 different types of cells in this region of the brain. But a close comparison of 75 of these b

23、rain cell types revealed small differences.“Those cells are the immune(免疫的)cells of the brain,” Nowakowski says. “ And you might imagine that studies or insights into neuroimmune (神经免疫）disorders, for example, might be vastly affected by this difference.“ And that could be one reason experimental Alz

24、heimers drugs have helped mice, but not people.1.Why do the researchers compare mouse and human brain cells?A. To develop some kinds of drugs. B.To improve accuracy in treatment.C. To find a way to cure brain disorders. D.To look for the reason for some medical failures.2.What makes many drugs effec

25、tive for mice but not for people?A. The effects of different parts of the genes. B.The response of the chemical materials.C. Small but important differences in brain cells. D.Different gene expressions of different cells.3.What do the researchers expect of the result they have found?A. Itll solve th

26、e present problem soon. B.Itll give them the proper assistance to further study.C. Itll be very helpful for all diseases. D. Itll help speed up the study of the genes.4.Where is this text most likely from?A. A diary. B. A guidebook. C. A novel. D. A newspaper.4、It is a question that has long puzzled

27、 scientistsexactly why are tigers orange? One might think it makes them more obvious-particularly against a leafy green forest background. William Blake summed it up in his famous poem known by generations of schoolchildren: “Tyger, tyger, burning bright /In the forest of the night.” But now the ans

28、wer is at hand.While obvious to us, computer simulations (模拟) of what the big cats look to the main animals they hunt for, deer, show a different picture. Humans with normal colour vision, can see red, blue and green colours. But deer can only pick up blue and green light, they are effectively colou

29、rblind to the colour red, like some humans. It means the tigers orange colouration looks green to them, allowing them to mix perfectly into the background, new research claims.Dr John Fennell at the University of Bristol and colleagues said that they used computers to estimate how noticeable a given

30、 animal was. They did this by using images of the environment in which the animal lives, and then creating images to see whether the camouflage helps the animal to mix in.Dr Fennell writes that by simulating what the world looks like to animals who are “two-colour vision”someone who cannot discover

31、the difference between red and green“we also identify the most suitable colours for hiding and visibility”.Dr Fennell writes in the Royal Society Journal Inter face: “Considering the coat of a tiger, it has fur that appears orange to a three-colour vision observer rather than some shade of green, th

32、ough the latter should be more appropriate color for an attack hunter in forests. However, when viewed as a two-colour vision observer, the tigers colour is very effective.”The question then arises as to why tigers dont grow green coats. Dr Fennell and colleagues write that mammals (哺乳动物) are not able to produce green fur. To do so would “require a significant change to mammalian biochemistry”. There is only one mammal known to have green fur but this is achieved through what might be con
