Few of us make money by losing sleep.But three graduate students at Brown University in Providence built a company around sleep deprivation  . 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   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   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. 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

Q: Games are a good form of teaching or training children as they combine fun with  knowledge. They make the teaching or training activities more interesting. They are useful in all fields of teaching and training. Help your child discover just how much more is going on in the world around them with this listening game. It will also provide a few minutes of peace and quiet in what is probably a very noisy and busy day. A discussion of the sounds you each hear will also assist in language development and an ability to articulate that which was heard. The sit-and-listen game is especially helpful if your child is at the stage of developing language skills: listening, speaking and so on. Method: This is a very relaxing activity in which you both need to sit still and silent for about 30 seconds and just listen to the world around you. You are both trying to hear as many different things as you can, whether they are cars, people, airplanes, water running, the wind in the trees or any other kinds of daily sounds. After the given time is up, having a chat about what you both could hear. It is a good idea to ask your little one some open ended questions to promote their language development, such as: "What were the loudest sounds you heard?" "What were the closest sounds you heard?" "How many cars did you hear?" "How far away do you think that barking dog might live?" "What sounds did you hear which you did not expect to hear?" Note: As an extension activity you may wish to draw a picture of all the things you could hear. After a discussion of the sounds, you can ask your child A) to write a diary B) to dictate the new words learnt C) to draw a picture of the happenings D) to imitate the sounds he/ she has heard
A: C


*Question*
My mother-in-law, Dorothy, is showing me the red notebook that's almost as precious to her as my husband's baby pictures. Inside the notebook is a list of the books she has read since 2007. For some people waking up in the middle of the night is a terrible thing. But for my mother-in-law, that time is a gift. At 87, she is getting the education she never had by working her way through great literature. She has now read close to 100 books, including every single novel by Anthony Trollope, Charles Dickens, Jane Austen, Edith Wharton, Henry James and Thomas Mann. My mother-in-law discusses her passion with the enthusiasm of a young girl, although she can also be a very tough critic, writing "VG' for " very good" in the margins next to her favorites. So far, only a handful of books have received the top prize. Born in Ridgefield, Conn, Dorothy was the youngest daughter of an Italian gardener. She taught herself English by reading The New York Times. Eager to come to Manhattan, she became a nurse, married a dentist and spent the next several decades keeping the house and raising a family. In her later years, she put her nursing skills to good use by taking care of my father-in-law, who had lung cancer. There were many trips to the emergency room in the middle of the night and then a long hospital stay. She stayed awake to watch over him for 15 hours a day. Always a light sleeper, she developed sleeplessness as a result of the stress. It worsened after he died. Deeply sad and lonely for the first time in her life, she began waking up around 2am. Julian and Sylvia, the elderly couple next door suggest she read literature. And so Julian, a great lover of literature, became her "professor", providing books from his large library. Suddenly turned onto a world of amazing characters. Why is Dorothy considered a tough critic? A) Because no books are inspiring enough in her eyes. B) Because only a few books are thought highly of by her. C) Because she only reads books by famous writers. D) Because she finds fault with every book she reads.
