Read the following article and answer the question. Article: Regularly staying late at the office significantly increases the risk of having a stroke or heart attack, researchers have found, working just an hour extra each day pushes up stroke risk by 10 per cent, according to a huge review of working patterns. And people who work an extra three hours a day--or 55 hours a week--are 33 per cent more likely to have a stroke, the scientists found. The research, published in the Lancet medical journal, is based on health records of more than 500, 000 people across Europe, the US and Australia. Scientists led by University College London warned that people who work longer hours tend to do less exercise, sit at a computer for hours at a time and drink more than people with a better work-life balance. Repeated stress may also be to blame for greater health problems, the scientists think. They looked at the combined result of 17 previous studies, in which 529, 000 people were tracked over an average of seven years. Experts stressed that the study had only found a link between hours worked and heart problems---it had not proved what had actually caused each death. But they warned people to take note of the findings. Dr Tim Chico, consultant cardiologist at Sheffield Teaching Hospitals, said "For many people, reducing their working hours would be difficult or impossible, and this study does not show that it would reduce the risk of stroke." Most of us could reduce the amount of time we spend sitting down, increase our physical activity and improve our diet while working and this might be more important the more time we spend at work. Question: Which factor is NOT the cause of the higher risk of health problems? Answer:

OPTIONS:
- Excessive drinking.
- A healthy diet.
- Repeated stress.
- Lack of exercise

Answer: A healthy diet.

Read the following article and answer the question. Article: I was brought up in the British, stiff upper lip style. Strong feelings aren't something you display in public. So, you can imagine that I was unprepared for the outpouring of public grief at a Chinese funeral. My editorial team leader died recently after a short illness. He was 31. The news was so unexpected that it left us all shocked and upset. A female colleague burst into tears and cried piteously at her desk. Somehow we got through the day's work. The next day was the funeral. Our big boss stepped forward to deliver a eulogy and was soon in tears. She carried on, in Chinese of course, but at the end said in English: "There will be no more deadlines for you in heaven." Next came a long-term colleague who also dissolved in tears but carried on with her speech despite being almost overcome by emotion. Then a close friend of the dead man paid tribute, weeping openly as he spoke. Sorrow is spreading. Me and women were now sobbing uncontrollably. Finally, the man's mother, supported between two women, addressed her son in his coffin. She almost collapsed and had to be held up. We were invited to step forward to each lay a white rose on the casket. Our dead colleague looked as if he was taking a nap. At the end of the service I walked away from the funeral parlor stunned at the outpouring of emotion. In the UK, families grieve privately and then try to hold it together and not break down at a funeral. Here in China it would seem that grieving is a public affair. It strikes me that it is more cathartic to cry your eyes out than try to keep it bottled up for fear of embarrassment, which is what many of us do in the West. Afterwards, a Chinese colleague told me that the lamenting at the funeral had been restrained by Chinese standards. In some rural areas, she said, people used to be paid to mourn noisily. This struck me like something out of novel by Charles Dickens. But we have all seen on TV scenes of grief-stricken people in Gaza and the West Bank, in Afghanistan, Iraq and the relatives of victims of... Question: This passage talks mainly about _ . Answer:

OPTIONS:
- an editor's death
- funeral customs
- cultural differences
- western ways of grief

Answer: cultural differences

Read the following article and answer the question. Article: When two Bangs meet Sheldon Cooper is a scientific genius on the popular American TV show, The Big Bang Theory (<<>> ). He finally met his match last year: Stephen Hawking. This is not the first time that the scientist has appeared on TV. He has also been on Star Trek (in 1987) and The Simpsons (in 1989). Each time, he played himself. Hawking, 71, is perhaps the world's most famous scientist after Albert Einstein. He has spent his whole life studying the beginning and the end of the universe, including the Big Bang theory. The Big Bang theory explains the early development of the universe. According to the theory, about 13.7 billion years ago everything was all squeezed together in a tiny, tight little ball, and then the ball exploded. The results of that explosion are what we call the universe. Hawking has always tried to make science more popular with people. His book: A Brief History of Time was published in 1988. In the book he shares his understanding of the universe in simple language. The book tries to explain many subjects about the universe to common readers, including the Big Bang, black holes and light cones . Hawking's achievements are even greater if you think about his disability. When he was 21, Hawking caught a bad illness that slowly stopped him from moving or talking. Now he sits on a wheelchair with a computer by his side. To communicate, he moves two fingers to control the computer's mouse. He chooses his words from the screen, which are then spoken by a voice synthesizer . Hawking also believes that there might be aliens in space. However, he believes they are probably very dangerous, so we should not look for them. "I imagine they might exist in very big ships ... having used up all the resources from their home planet," Hawking said in a British documentary named Into the Universe with Stephen Hawking. Question: The Big Bang theory mainly explains _ . Answer:

OPTIONS:
- how the universe started
- what the universe is like
- how old the universe is
- how the universe exploded

Answer: how the universe started

Read the following article and answer the question. Article: It is reported that today in China, 50% of people who write blogs do so as a personal diary and 83% use their blogs for sending messages to friends. It is also found that there is a strong East-West difference. In places like the US, blogs that offer information on news attract more readers but in China, blogs are more likely to be about sharing personal feelings. It seems that bloggers can be divided into three types: IT bloggers, bloggers who record their ordinary feelings and media bloggers. When blogging first started, the IT people had the technological advantage and they took the chance to put their thoughts on the web. Some of these IT people read their blogs. The next wave of bloggers did not have any training as writes or in IT and wrote about normal daily life. Media bloggers, however, are trained writers, such as journalists and editors. When the many media bloggers showed up, the everyday blogs lost most of their readers. Media bloggers have the advantage of knowing how to communicate well through the written word. However, the normal bloggers are still out there and increasing in number. It seems that blogging is the new way to express your feelings. People feel like the world is listening to, or rather reading, their problems, even if they are not . Question: What type of text is this? Answer:

OPTIONS:
- A blog.
- A diary.
- A news report.
- A school textbook.

Answer:
A news report.
