Article: Whether you prefer burning the midnight oil or going to bed early so you can get up at the break of dawn depends on your genes , according to experts. I jump out of bed each morning, eager to start an active day. But I can hear my neighbour's alarm clock ringing non-stop every morning and I doubt he gets to work on time. A lot of noise comes from his flat in the evening. He's happy to stay up watching TV till after midnight, while I go to bed early and try to sleep. Well, it might not be his fault after all. I'm called 'a lark ' and my neighbour 'an owl '. We all have inside 'clocks' in the brain to control all kinds of bodily functions and it is reset every day by light. These inside clocks run to a different schedule in 'larks' and 'owls'. If you have a fast clock, you like to do things early, and if you have a slow clock, you like to do things late. Because we live in a 24/7 world, scientists believe it's important to understand a person's 'chronotype' - the time of the day when they function the best. It could help us lead a healthier life. A US professor has studied sleeping patterns and thinks work times should be changed and made more individual to fit in with our chronotypes. And he has advice for those who can't choose their working hours: "If that's not possible, we should be more careful about light exposure", says the professor. "You should try to go to work not in a covered vehicle but on a bike. The minute the sun sets we should use things that have no blue light, like computer screens and other electronic devices." Question: Things with blue light are not recommended after sunset because blue light _ . - will make you nervous - may cause sleep problems - will reduce your work effect - may make you sleepy
may cause sleep problems

Read the following article and select the best answer. Article: There was a 17% fall in the number of first year undergraduates at UK universities in the first year of higher tuition fees, official figures show. In 2012-13 UK universities were allowed to _ their yearly fees to PS9,000. England saw a 12% fall in new full-time undergraduate students overall. The government acknowledged the fall but stressed that demand for full time higher education has already "returned to record levels". A spokesperson for Department for Business, Innovation and Skills said the figures were influenced by a higher number of students taking up places the previous year, rather than having a gap year. "A reduction in entrants in 2012 was well documented and the numbers were affected by the significant number of students who opted not to defer their place from the year before," she said. 'Direct consequence' The decline had not continued into the current year, she added. "Application rates for some of the most disadvantaged young people have risen to an all time high in England and more students than ever before are being successful in securing a place at their first choice institution." The figures, collated by the Higher Education Statistics Agency (Hesa), are official confirmation of other indications that there was a fall in the number of people going to university last year. Previously released figures had shown declines in applications and offers of places, and the admissions body Ucas also reported a fall. Question: What is the main idea of the passage? - The number of undergraduates in Uk has decreased due to the higher fees . - The government says undergraduate numbers have 'returned to record levels'. - The reduction is the direct result of the significant number of students who opted not to defer their place from the year before. - Application rates for some of the most disadvantaged young people have risen to an all time high in England

Q: Read the following article and select the best answer. Article: "Does my smile look big in this?" Future fitting-room mirrors in clothing stores could subtly adjust your reflection to make you look - and hence feel - happier, encouraging you to like what you see. That's the idea behind the Emotion Evoking System developed by Shigeo Yoshida and colleagues at the University of Tokyo in Japan. The system can manipulate, or in other word, control your emotions and personal preferences by presenting you with an image of your own smiling or frowning face. The principle that physiological changes can drive emotional ones - that laughter comes before happiness, rather than the other way around - is a well-established idea. The researchers wanted to see if this idea could be used to build a computer system that manipulates how you feel. The system works by presenting the user with a web-camera image of his or her face - as if they were looking in a mirror. The image is then subtly altered with software, turning the corners of the mouth up or down and changing the area around the eyes, so that the person appears to smile or frown . Without telling them the aim of the study, the team recruited 21 volunteers and asked them to sit in front of the screen while performing an unrelated task. When the task was complete the participants rated how they felt. When the faces on screen appeared to smile, people reported that they felt happier. On the other hand, when the image was given a sad expression, they reported feeling less happy. Yoshida and his colleagues tested whether manipulating the volunteers' emotional state would influence their preferences. Each person was given a scarf to wear and again presented with the altered webcam image. The volunteers that saw themselves smiling while wearing the scarf were more likely to report that they liked it, and those that saw themselves not smiling were less likely. The system could be used to manipulate consumers' impressions of products, say the researchers. For example, mirrors in clothing-store fitting rooms could be replaced with... Question: What can we learn about the web-camera image in the study? - It recorded the volunteers' performance in the task. - It gave the volunteers a false image. - It attempted to make the volunteers feel happier. - It beautified the volunteers' appearance in the mirror.
A: It gave the volunteers a false image.

Q: Read the following article and select the best answer. Article: An upper class British lady once declared: " Anyone seen on a bus after the age of 30 has been a failure in life." This may sound arrogant and ignorant. Unfortunately, there are still people thinking that way. Some wealthy folk in the West look down on buses and boast about how many years it has been since they last travelled by one. How sad is that? Our roads are packed with cars and the air is full of the pollution they emit. But still, many car users are unwillingly to get on a bus or a bike or a train to take themselves to work. It's convenient to drive, they'll say. Buses are so unreliable, they'll claim. And trains are expensive - at least in the UK. It's an attitude which may have to change. It doesn't make sense to drive a car in a city where there's a public transport system. Also, these rush hour commuters usually travel alone. As a result, transport authorities in the UK are looking at solutions to city center congestion . One is to increase the number of parking spaces at out-of-town railway stations. More motorists can then leave their cars and travel into the city by train. Light rail or tramways are another environmentally friendly solution. Many cities across Europe have had light rail or tramway systems. The subway in London is used by everyone, rich and poor. It's the quickest way of getting around the city, whatever your bank balance. And then there are the cycle hire plans you find in many modern cities. In London and Paris, you can hire a bike by the hour to get you where you need to go. Mayor of London, Boris Johnson, is often pictured cycling to work. David Cameron, the British prime minister, cycled to the House of Commons before he became leader. Question: Which of the following is NOT the reason why some car users are unwilling to change their way of transport? - It's convenient to drive around the city. - They cannot count on buses. - It costs them much money to take trains. - Driving cars has little effect on environment.
A: Driving cars has little effect on environment.
