More and more people are taking their tablets to bed with them to surf the web, check Facebook or email before switching off the light. But researchers are warning that the blueish light their screens emit can stop users getting a good night's sleep. That is because this type of light mimics daylight, convincing the brain that it is still daytime. Blue light suppresses production of a brain chemical called melatonin, which helps us fall sleep. This is because our brains have evolved to be wakeful during daylight hours. By contrast, light which is more orange or red in tone does not reduce melatonin production, perhaps because our brains recognize it as a cue that the day is ending. Neurologists have known for years that staring at screens late in the evening can disrupt sleep. Researchers at the Lighting Research Centre, at the Rensselaer Polytechnic Institute in New York, are warning that looking at tablet displays for more than two hours "leads to a suppression of our natural melatonin levels as the devices emit optical radiation at short wavelengths" - in other words, they emit bluer light. They say: "Although turning off devices at night is the ultimate solution, it is recommended that if these devices are used at night displays are dimmed as much as possible and that the time spent on them before bed should be limited." They drew their conclusions after measuring melatonin levels in 13 volunteers, after they had spent time viewing iPads at full brightness at a distance of 10 inches, for two hours. Melatonin levels were significantly lower after they had done this, than they were after the volunteers had viewed their iPads for the same time, but while wearing orange glass goggles, which cut out the blue light. They wrote in the journal Applied Ergonomics that tablet makers could "tune the spectral power distribution of self-luminous devices " so that they... Question: We can infer from the passage that _ . Options: A: Orange and red light does no good to a good night's sleep. B: Our brains recognize orange or red light in tone as a cue that the day is ending. C: The less melatonin our body produces, the easier we fall asleep. D: Too much late night screen time leads to more than sleep problem.

They are offered a chance to explore different things: nature, sports, music, technology ----even business and economy. One such program for high school students in the Pacific Northwest is called Washington Business Week. The program began in 1975. Officials say forty-five thousand people have attended Washington Business Week. Other states now have similar camps. Washington Business Week describes itself as a way to learn more about how to plan for the future in an ever-changing economy. Students form an executive management team. They lead an imaginary company to financial success. The camp is held at three colleges in Washington State. The high school students live in the college housing. The cost of the camp is almost three hundred dollars, but families can receive financial assistance . Some business camps are free. These are for students from poor areas. The National Foundation for Teaching Entrepreneurship (NFTE) is an organization based in New York City that supports such camps. It has programs around the United States and its Web site lists international partners in China, Tanzania and a few other countries. NFTE says it has served more than one hundred thousand young people since 1987. Among other business camps is Camp C.E.O.. C.E.O is an chief executive officer. And this camp is for girls only. Camp C.E.O. is supported by the Girl Scouts of America and takes place for one week each summer. The camp took place last month in Tennessee. The girls worked with successful businesswomen from different industries. The girls learned how to build a business and develop an idea into a product. And, we imagine, they also had some fun. Question: Which of the following is True about NFTE? Options: A: It offers financial help to all students. B: It has programs in America and some other countries. C: It was organized by many rich New Yorkers. D: One of its aims is to train students to be business managers.

Q: Read the article and select the best answer. Article: "At least you'll be close to home!"That phrase dominated the weeks before my move to my college.I took comfort in knowing that home was close by if I needed it The night before the move,I spoke with a sophomore friend of mine who was moving back the next morning.I asked if he was sad to be leaving home and his response sparked in me an internal debate."It was nice to be back but honestly. I've come to think of the college as my home."Up until that moment,the move to college seemed like an extended version of summer camp.School wasn't a home;it was a place for me to explore when I was away from home right? As I packed my things,I really started thinking about the concept of home,and I couldn't help but wonder would I ever consider college my own home? The next day,once my bags were unpacked and my parents were gone,I took a moment to look around my dorm.It was absolutely nothing like my room...no _ ,no blue curtains and no queen--sized bed.Despite the fun I was having and things I was learning in the following Welcome Week,I couldn't bring myself to call it home.I longed for my _ .I even wanted my mom's calls."There's no place like home."I murmured. Last night,I went to visit my friends and we spent the next hour talking about that missing feeling we all shared-our families,our friends,our old lives--and soon the sadness turned to fondness.One by one our friends came in to say goodnight and the room was filled with girls,all laughing and sharing our high school experiences.It wasn't until about l:00 a.m.that I turned to my roommate,unconsciously saying,"It's getting late...we should probably go home soon."I was taken aback by my own words.Somehow in the few hours,my dorm room had turned into a home.
