It’s a question anyone might ask in the future: Should your household robot be cool? Or practical?

For Sony Corporation, robots ought to be entertaining. The company’s 11 robot, SDR—4X, can sing and dance. But for automaker Honda Motor Co. Ltd, such 12 should perform useful tasks for their 13 masters.

“It is in the end a machine, a 14 ” said Masato Hirose, Honda’s chief engineer. Sony’s chief researcher Toshi Doi said robots performing such tasks as 15 for ill or disabled people would not necessarily need a human 16 . “The attractiveness of the SDR—4X is its 17 ”, he said. “It has feelings. It has instincts (直觉).”

Drawing from its 18 of 60,000 words, an SDX—4X robot 19 last week that it can ask a 20 in a high voice: “please 21 still for a minute while I memorize your face.” It also 22 off its ability to walk on uneven (高低不平的) floors, and come to its owner when it’s 23 .

While Honda’s robot is 24 used mainly for entertainment, it is 25 that one day it will be a useful companion. So its robots have been 26 to be 120cm tall—more than twice the height of the SDR—4X. Hirose said 120cm is the 27 a robot that moves around a home should be.

“If you are going to have something that can move with 28 in a human surroundings, then it is better to 29 the robot like a human,” he said.

Hirose said that he hopes the robot will be 30 enough so that he can buy one for himself and let it get him a beer.

Superman, Spider-Man, Batman and Iron Man …There is no shortage of superheroes. You find them in comic books, on the TV and the big screen.

In a survey of fans by the sci-fi and fantasy website, SFX.co.uk, Batman, 70 years old this year, was voted Britain’s favorite superhero.

Unlike many crime-fighting superheroes Batman has no special powers. He can't fly like Superman or shoot a sticky web like Spider-Man.

Bruce Wayne is born to a wealthy Gotham City business family. However, when his parents are murdered his life changes completely.

Wayne feels anger at their deaths and guilty that he did not prevent them. He travels around the world learning how to fight. Upon returning to Gotham, he creates a disguise to enable him to fight crime without being recognized.

A childhood fear of bats leads him to choose to dress as one. His idea is that through the bat persona, he can prove to himself that he has overcome his childhood fears.

Wayne is the CEO of the company he inherits from his father. He seems to live the lifestyle of a millionaire playboy. But this is a ruse (计策). He works hard at the image to allow himself the freedom he needs to do his work as a crime fighter. “Bruce Wayne, playboy” is the disguise; Batman is the real person.

“Wayne is not a born superhero. Instead, he is a real, complex person,”said Dace Golder, editor of the website. "He is the most realistic of all the superheroes. I am particularly interested in the emotional process by which a boy becomes a hero. His superhero qualities come from within.”

31. What is the article mainly about?

A. What makes a superhero.

B. How to overcome childhood fears.

C. How Bruce Wayne develops into a superhero.

D. Why superheroes enjoy great popularity in Britain.

32. Batman differs from other superheroes in that .

A. he doesn't have any special powers

B. he had an unhappy childhood

C. he was not a born superhero

D. he does his best to fight crime

33. Bruce Wayne decides to dress like a bat because of .

A. his curiosity about bats

B. his unusual travel experiences

C. his parents' sudden death

D. his childhood fear of bats

34. Why does Wayne live like a playboy?

A. He prefers the lifestyle of a playboy.

B. He needs to disguise his crime fighting activities.

C. He loves freedom more than anything else.

D. He doesn't know how to run a company.

35. Which of the following statements is true about Batman?

A. The turning point of his life is due to his parents' sudden death

B. He has special powers

C. Batman is a born superhero

D. He actually lives the lifestyle of a millionaire playboy

Batteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri(MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient.

“To provide enough power, we need certain methods with high energy density(密度)”，said Jae Kwon, assistant professor of electrical and computer engineering at MU. “The radioisotope(放射性同位素) battery can provide power density that is much higher than chemical batteries.”

Kwon and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro / nanoelectromechanreal systems (M/NEMS). Although nuclear batteries can cause concerns, Kwon said they are safe.

“People hear the word ‘nuclear’ and think of something very dangerous,” he said, “However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems.”

His new idea is not only in the battery’s size, but also in its semiconductor(半导体). Kwon’s battery uses a liquid semiconductor rather than a solid semiconductor.

“The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure(晶体结构) of the solid semiconductor,” Kwon said, “By using a liquid semiconductor, we believe we can minimize that problem.”

Together with J. David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery. In the future, they hope to increase the battery’s power, shrink its size and try with various other materials. Kwon said that battery could be thinner than the thickness of human hair.

36. Which of the following is true of Jae Kwon?

A. He teaches chemistry at MU.? B. He developed a chemical battery.

C. He is working on a nuclear energy source.

D. He made a breakthrough in computer engineering.

37. Jae Kwon gave examples in Paragraph 4_________.

A. to show chemical batteries are widely applied.

B. to introduce nuclear batteries can be safely used.

C. to describe a nuclear-powered system.

D. to introduce various energy sources.

38. Liquid semiconductor is used to _________.

A. get rid of the radioactive waste??

B. test the power of nuclear batteries.

C. decrease the size of nuclear batteries

D. reduce the damage to lattice structure.

39. According to Jae Kwon, his nuclear battery _______.

A. uses a solid semiconductor???????

B. will soon replace the present ones.

C. could be extremely thin??????????

D. has passed the final test.

40. The text is most probably a ________.

A. science news report???? ?B. book review???

C. newspaper ad?? D. science fiction story

I used to watch a little girl playing basketball every day from my kitchen window. One day I asked her why she practiced so much. She said, “I want to go to college. The only way I can go is to get a scholarship. I like basketball and I want to be the best player in colleg
