Read the article and select the best answer. Article: Some colors people see late at night could cause signs of clinical depression . That was the finding of a study that builds on earlier study findings. They show that individuals who live or work in low levels of light overnight can develop clinical depression. Doctors use the word "clinical depression" to describe severe form of depression. Signs may include loss of interest or pleasure in most activities, low energy levels and thoughts of death or suicide. In the new study, American investigators designed an experiment that exposed hamsters to different colors. The researchers chose hamsters because they are nocturnal, which means they sleep during the day and are active at night. The animals were separated into four groups. One group of hamsters was kept in the dark during their night-time period. Another group was placed in front of a blue light, a third group slept in front of a white light, while a fourth was put in front of a red light. After four weeks, the researchers noted how much sugary water the hamsters drank. They found that the most depressed animals drank the least amount of water. Randy Nelson heads the Department of Neuroscience at Ohio State University. He says animals that slept in blue and white light appeared to be the most depressed. "What we saw is that these animals didn't show any sleep uneasiness at all but they did mess up biological clock genes and they did show depressive sign while if they were in the dim red light, they did not." Randy Nelson notes that photosensitive cells in the eyes have little to do with eyesight. He says these cells send signals to the area of the brain that controls what has been called the natural sleep-wake cycle. He says there's a lot of blue in white light. This explains why the blue light and white light hamsters appear to be more depressed than the hamsters seeing red light or darkness. Question: What can help people who work late at night to avoid being depressed? Options: A: Not being exposed to dim red light when using computers. B: Equipping their computer screens to put it more in the reddish light. C: Living or working in low levels of light overnight. D: Going to see doctors of clinical depression regularly for help.

Read the article and select the best answer. Article: I was at a dance club when I was nineteen. One day my new friend walked with me to my car. It was a very cold night. As we were walking to my car, a man walked up to us. Behind him was a woman pushing _ with a child inside who was about 2 years old. The child had only a jacket on and it wasn'tzipped . The man began to tell us he wanted to borrow some money for the night and that he had a job but no place to live and was waiting for his first paycheck. He confirmed he could get our mailing address and mail the money back to us. The guy I was with reached into his pocket to give this man a $20 bill. As the man was extending his hand out to take the money, I put my hand on my new friend's hand and said, "Can I talk to you for a minute?" I told him some people earned money by begging and that they always cheated those with soft hearts. And if they were truly worried about their child being out in the cold, they would have at least zipped his jacket. My friend looked at me with disapproval and said, "Michael, I know there are some people out there that take advantage of others. I also know some people out there that are one paycheck away from being homeless. If I gave $20 to 10 people and only one of them really needed it and used it for the right thing, it was worth it." I am now thirty-seven years old and have never forgotten what he said to me. I don't even remember his name now. But I do remember that this experience changed my perspective . Question: When the story happened, the author _ Options: A: was in his late thirties B: served as a car repairman C: had much money in his pocket D: was walking towards his car with his friend

Ques: Read the article and select the best answer. Article: He wasn't sick. He wasn't old. And he wasn't losing. He had a very good final season and won his last game in 2008. And then he walked away. Lloyd Carr was 62. That's a few years earlier than retirement age in America and many years earlier than some college football coaches say goodbye. How was Carr, who coached University of Michigan, able to leave so easily? " It can be _ ," Carr admits. "The Saturday afternoons and the crowds. And when you win, there's nothing like it." But the job needs hard work. The pressure to win. The endless training. The hours are so long that sleeping at the office is a normal thing. I reported Carr's career at Michigan from 1995 to 2007. I saw him run onto the field before 100,000 cheering fans, saw him enjoy a share of a national championship with a 12-0 season. And when I visited him recently in retirement, the difference was noticeable. He seems much calmer, relaxed, more at peace. He says, "As much fun as it is, there's a period when you have other things to deal with." Carr knew he wanted to travel, see the world, read more, do other work. He is now connected with a children's hospital, does some speaking, plays golf, and enjoys relaxing with his wife, Laurie, and their many grandchildren. Several of today's big-name coaches are all about Carr's retirement age. Nick Saban turns 59 this month. Jim Tressel is 57. Frank Beamer is already 63. None of them seems to be slowing down. So when, I ask Carr, is the right moment to leave such a great job? He thinks. Finally, he says, "When you love it and can still walk away from it. That's the right moment." Question: The author is most probably _ . Options: A: a football player B: Lloyd Carr's assistant C: a retired coach D: a sports reporter
Ans: D

Read the article and select the best answer. Article: Infiniti, Nissan's luxury brand, continues to show off ideas for the future. The Q80 Inspiration here in Paris is an excellent piece of work, perhaps a concept elegant enough to make us forget that Infiniti's former Hong Kong-based president, Johan de Nysschen, moved to take over General Motors' Cadillac car brand in July and Infiniti chairman Andy Palmer is the new CEO at Aston Martin, the British luxury car brand. The Q80, if it becomes reality, will be brought to market by Infiniti's new boss, former BMW (another famous car brand )executive Roland Kruger. He should focus on this, at least until he is head-hunted to another company. The Q80 Inspiration is a low and sexy four-door fastback, and it is also a showcase for technology - from autonomous driving to eco-friendly power trains. Here in Paris, the Infiniti people say the hybrid drive in this concept suggest exactly where the brand is going in the future. The company says the Q80 speaks to how Infiniti plans to pull people into more expensive cars - cars that compete with the Porsche Panamera, for instance. Alfonso Albaisa, Infiniti Executive Design Director, said the car "delivers feminine elegance and muscular menace in equal measure and strikes big in terms of styling, craftsmanship, choice of materials and attention to detail." Most importantly, for luxury cars buyers who are increasingly puzzled by all the technology, the designers focused on making things simple. "There is a tendency with modern design that every time you add interior features and technology you add complexity," said Albaisa, pointing to the concept's easy-to -understand -and -operate infotainment interface. As for power, the Q80 Inspiration gets 550 horsepower from a twin turbocharged 3.0-litre V-6 combined with a hybrid electric power train. Fuel economy could be as good as 5.5 litres/100 km. Question: Who will take charge of the launch of the Q80 Inspiration? Options: A: Andy Palmer B: Alfonso Albaisa C: Johan de Nysschen D: Roland Kruger
