Three-Dimensional （3D） movies have been becoming more and more popular in recent years．It seems 3D TV sets may be going into family households in the near future．While new digital 3D technology has made the experience more comfortable for many, for some with eye problems, long 3D viewing may result in an aching head, doctors say．
"There are a lot of people walking around with very minor eye problems, which under normal situations, the brain deals with naturally," said Dr Michael Rosenberg, an ophthalmologist （眼科医师） in Chicago．He said in a 3D movie, these people face a completely new sensory experience．"That translates into greater mental effort, making it easier to get a headache," Rosenberg told Reuters．
In normal vision, each eye sees things at a slightly different angle．"When that gets processed in the brain, that creates the perception （感觉） of depth," said Dr Deborah Friedman, an ophthalmologist in New York．The images people see in three dimensions in the movies are not calibrated （校准的） in the same way that their eyes and brain are．"If your eyes are a little off to begin with, then it’s really throwing a whole degree of effort that your brain now needs
to exert （竭尽全力）," he said．
Dr John Hagan, a Kansas City ophthalmologist, said some people who do not have normal depth perception cannot see in 3D at all．He said people with eye muscle problems, in which the eyes are not pointed at the same object, have trouble processing 3D images．
Rock Heineman, a spokesman for RealD, a provider of 3D equipment to theaters, said headaches and nausea were the main reasons 3D technology never took off．
Heineman said older 3D technology used two film projectors（放映机）, one that projected a left-eye image and one that projected a right-eye image．Three-D glasses would allow viewers to see a different image in each eye．
"People often complained of headaches and it was really because the projectors weren’t lined up," Heineman said．
Now his company has developed a new single digital projector, which switches between the left and the right-eye image 144 times a second, to help overcome some of the old problems．
"By going to a single digital projector, those problems were solved," he said．Friedman said he thinks most people will do fine with 3D movies and with 3D TVs, but Rosenberg said people may quickly tire of the novelty （新鲜事物）．"I suspect there will be a lot of people who say it’s sort of neat, but it’s not really comfortable," he said．The text is mainly about ____．
| A．the reasons why people like 3D movies |
| B．how to improve 3D technology |
| C．the development of 3D technology in recent years |
| D．causes of headaches and nausea when people watch 3D movies |
The underlined phrase "took off" could be replaced by "______"．
| A．became popular |
| B．flew in the sky |
| C．left hurriedly |
| D．removed one’s clothes |
This article implies that _____．
| A．people do not like new things like 3D movies |
| B．3D TVs will completely take the place of old TV sets |
| C．3D technology is the most important technology ever |
| D．those with eye muscle problems should not watch 3D movies |
We can learn from what Rosenberg said in the last paragraph that
| A．a single digital projector could solve all the problems with 3D technology |
| B．people will gradually become comfortable with 3D movies and TVs |
| C．the appeal of 3D movies and "TVs may fade |

Sitting by her Pinocchio lamp, she smiled at me as her tiny hands’ shadow danced on the bedroom wall．"A rabbit!" she laughed with all the delight of a four-year old．Her blue eyes shone with pride as she showed me the animated image she had created．"Daddy, will you show me how to make a tiger?" she asked．"Sure," I said, "and then we’ll read a story and tell your angels goodnight．"To my youngest daughter, that meant her bedtime prayer．
Today my daughter is seven, and I no longer get to read the story．She reads it to me, complete with expressive accents for the story characters．
To say I’m proud of our relationship would be an understatement．We have shared days of joy as well as tragedy．Our time together has strengthened the relationship of love and special "life stuff" that is all our own．
I am richer for having planted the spirit of trust in this gentle little person; we have grown together spiritually, learning much from each other．The special times we spend together, like nights by a Pinocchio lamp, create memories that we will treasure for the rest of our lives．
So it is with all of our relationships．The trust factor is vital for relationships to develop．Think of one of your fondest memories, and you will no doubt find a remarkable relationship at its center--one with a spiritual quality that shines outward from the heart．
Time together, caring acts, and unconditional love build trust．I suggest that we each spend plenty of time with our personal "Pinoechio lamps"--those special ways that we choose to strengthen our relationships．
Relationships take time to develop and maintain．It is not always easy, but the results are priceless．"Nights by a Pinoechio lamp", wherever those might be for you, will create enduring relationships of golden "life stuff", spiritual gifts that no one can take away．The underlined words in the third paragraph refer to all EXCEPT ______．

Few of us make money by losing sleep．But three graduate students at Brown University in Providence built a company around sleep deprivation （睡眠不足）．
Jason Donahue, Ben Rubin and Eric Shashoua were working late nights in Brown’s business and engineering schools．They began thinking about ways to sleep better．They discovered they weren’t alone in burning the midnight oil．Around 20% of Americans get less than six hours of rest a night．
The friends imagined a smart alarm clock that could track how much time people spend in the most restorative （有回复作用的） stages of the sleep cycle: REM （rapid eye movement） and deep sleep．What would it cost to design such a thing? Five years of research, 20 employees, $14 million and a whole lot of doubting from investors and scientists．
Their company, Zeo, based in Newton, Mass, launched its product in June, 2009．The Zeo device uses a headband with tiny sensors （传感器） that scan your brain for signs of four sleep states- REM, light, deep and waking sleep．The smart alarm clock displays a graph of your sleep pattern and wakes you as you’re not in REM sleep （which is when you’re least groggy）．In the morning you can upload the data to the company’s Web site, and so track your sleep over time．Most of the feedback comes in the form of Zeo’s ZQ score showing how well you’ve slept．
"Zeo allows people to unlock this black box of sleep," says Dave Dickinson, a health-care CEO．
Whether any of this actually improves sleep is up to the consumer, who will also need to make lifestyle changes like cutting out alcohol before bedtime or caffeine after 3 pm．
For now the company is selling Zeo online only．Dickinson also plans to spread it to countries such as Australia, where sleep deprivation approaches US levels．Who will support Zeo?
| A．People full of imagination． | B．People suffering sleeping problems． |
| C．People having access to the Internet． | D．People having bad lifestyles． |
Why did the three graduate students imagine a smart alarm clock?
| A．To wake them up on time in the morning． |
| B．To earn enough money for their study． |
| C．To improve the quality of people’s sleep． |
| D．To enjoy their life while working at night． |
To design the Zeo device, the three graduate students ____．
| A．spent much time and money | B．were widely supported by scientists |
| C．worked by themselves all the time | D．attracted many investors |
What can we know from the passage?
| A．Zeo has a direct effect on users’ lifestyles． |
| B．It needs more personal efforts to make Zeo function better． |
| C．A large quantity of Zeo devices have been sold in Australia． |
| D．Consumers can go to the Zeo company to purchase Zeo in person． |
For many people, the name Baskin-Robbins is linked to sweet memories of eating ice cream．Irvine Robbins, who helped create this famous company, died in May at the age of ninety．His life’s work of making fun and exciting ice cream flavors changed the way Americans enjoy this food．
Irvine Robbins opened his first ice cream store in 1945 in California．At the time, there were no stores that sold only ice cream．His sister’s husband, Burton Baskin, also opened his own ice cream stores．
In 1948 they combined their six stores into one business．Baskin and Robbins realized that they were too busy to operate each store well．So, they decided to sell part of each operation to the manager of that store．This permitted the company to grow quickly．
By 1953, they renamed their company Baskin-Robbins．They advertised that they sold 31 kinds of ice cream to show the many choices buyers had．There was one flavor for every day of the month．
Robbins and Baskin sold "Lunar Cheesecake" the day after astronauts landed on the moon in 1969．Other flavors included "ChaChaCha", for cherry chocolate chip, and Robbins’ personal favorite "Jamoca Almond Fudge"．They said: "We sell fun, not just ice cream．"
By 1967, there were 500 Baskin-Robbins stores in the United States．The business partners sold their company that year．Today, there are more than 5,800 Baskin-Robbins stores around the world．What is the main idea of the passage?
| A．The managers of Baskin-Robbins． | B．The start of Baskin-Robbins． |
| C．The production of Baskin Robbins． | D．The great success of Baskin-Robbins． |
From the text we learn that _____．
| A．Baskin-Robbins was the only shop selling ice cream in 1945 |
| B．Baskin-Robbins was famous for their special ice cream flavors |
| C．Baskin-Robbins grew quickly because they combined their other stores together |
| D．there had been more than 5,800 Baskin-Robbins stores around the world by 1967 |
What was probably the main reason for Baskin-Robbins’ success?
| A．They sold not only ice cream, but fun． |
| B．They renamed their company． |
| C．They put all their hearts into the business． |
| D．They sold "Lunar Cheesecake"． |
It can be inferred from Paragraph 5 that

| B．Cherry chocolate chip sells best |
| C．Robbins and Baskin were good at inventing new ice creams |
| D．Lunar cheesecake was invented for the astronauts |
