1 （9分）某同学通过查找资料自己动手制作了一个电池.该同学想测量一下这个电池的电动势E 和内电阻r，但是从实验室只借到一个开关、一个电阻箱（最大阻值为9.999Ω，可当标准电阻用）、一只电流表（量程I g=0.6A，内阻忽略不计）和若干导线。（1）请根据测定电动势E、内电阻r的要求，用实线把图甲中的器件连接成实验电路；（2）接通开关，逐次改变电阻箱的阻值R，请先读出R=2.6Ω时电流表的示数（如图乙所示）I= 　　　　A，然后在图丙所示的坐标系中描出该点，最后把图丙中已经给出的点和你所描出的点中符合实际的点用平滑的曲线连接成R—1/I图像；（3）该实验中，R与1/I之间的线性函数关系式为　　　　　，根据图丙中描绘出的图线可得出这个电池的电动势E= 　　　　V，内电阻r= 　　　　Ω.

6 C Geniuses amaze us, impress us and make us all a little jealous．How do they differ from the average person? Scientists are working hard to figure out that answer．Tune in to the National Geographic Channel to find out about the discoveries they’re making in the series My Brilliant Brain. When Marc Yu was only two years old, he began to play the piano．After a year, he started learning pieces by Beethoven．Now he’s a world-famous concert pianist at age eight．He learns newer and more difficult pieces with ease and can identify any note he hears．He seems to be specially designed for music．In Born Genius, National Geographic looks at the science behind child prodigies (神童) to explain why some children seem to be born without limits. Genius didn’t come naturally to Tommy McHugh．His came only after he nearly died from bleeding in his brain．After recovering, McHugh’s head was filled with new thoughts and pictures．So, he began to express them in the form of poetry and art．Now, he’s a seemingly unstoppable creative machine．Sufferers of autism and brain injury have shown that great mental ability can sometimes come from damage or disease．Accidental Genius explores this puzzling relationship. Can normal people be trained to be geniuses? Susan Polger has shown no signs of extraordinary intelligence．Yet, during her childhood, she studied thousands of chess patterns and learned to recognize them immediately．As a result, she was able to beat skilled adult players by age 10 and can now play up to five games at the same time without even seeing the boards．Make Me a Genius examines what it takes to turn an ordinary brain into that of a genius. If becoming a genius were easy, we’d all be one．Yet, there is much more to super intelligence than simply being born lucky．Learn more about amazing brains this month on National Geographic’s My Brilliant Brain. 51．My Brilliant Brains is most probably from _______. A．a website B．the radio C．a magazine D．a newspaper 52．The author takes Marc Yu as an example to show that a child prodigy is . A．a person who learns something easily B．a child who is eager to learn new things C．a student who practices an instrument a lot D．a kid who works hard to do well in school 53．Which of the following is NOT true according to the passage? A．New things about the brain are still being discovered. B．People without natural abilities can learn to do things well. C．Some people naturally have more active brains. D．People are usually smarter when they recover from brain injury. 54．From the passage, we know that ___________ A．scientists completely understand the brain B．people can only be born as geniuses C．there’s no such thing as a true genius D．there are many factors in being a genius 55．The author develops the passage mainly by ___________. A．providing typical examples B．following the natural time order C．presenting a cause and analyzing its effects D．comparing opinions from different scientists
