Read the following article and select the best answer. Article: Housing Price in China has always aroused heated discussion among property developers and ordinary Chinese. To many property developers and local government officials, housing price in China is still low compared with many developed countries. However, the average housing price in the United States is only 8, 000 yuan per square metre, while in China, it is even higher than that in the United States. "This shows that there are some bubbles in Chinese real estate market," the International Finance News reported. Although the average price of residential houses in the United States, after changed to RMB, is about 8, 000 yuan per square metre, the houses in the US are not sold in terms of building area, as most Chinese property developers do when they sell their houses. If the US property developers sell their houses according to the building area, then the housing price will be even lower than 8, 000 yuan per square metre. In most big Chinese cities, such as Beijing, Shanghai and Shenzhen, houses are sold at a price even higher than those in the US. The high housing price in large cities in China proves that Chinese real estate market does have some bubbles. Moreover, Chinese houses cannot be compared with houses in the US in terms of building quality, environment and supporting facilities. Furthermore, it should be noted that American people's average income is several dozen times higher than that of Chinese people. How can the Chinese afford to buy a house which is even more expensive than that sold in the US? At the beginning of 2007, Chinese government issued a set of policies that aimed to benefit the public. Now in order to reduce the high housing prices, the government can regulate the real estate market by raising tax on property industry and controlling the release of loans and lands to property developers. Meanwhile, the government should allow people to build more houses through various fund-raising channels, such as funds collected from buyers or raised by working units. By applying these multiple...

Read the following article and select the best answer. Article: You're in your office when you learn there's someone with a gun wandering outside. You can hear gunshots and screams. What do you do? That's the challenge for users of a new virtual reality program called SurviVR, designed to train employees how to deal with an active shooter situation in the workplace. The program works with HTC Vive, the virtual reality headset released earlier this year. An active shooter situation is when an armed person or people actively shoot in a small, populated area with the intention to kill. There were 20 such situations in the United States last year and 20 the year before, according to FBI statistics, resulting in a total of 231 deaths. This year saw the deadliest active shooter situation in US history , with 49 people killed in a nightclub in Orlando. In the training situation, users have four choices. They can lock themselves in the office. They can hide, perhaps in the office closet. They can run for an exit. Or they can use something in the office--a computer or a cup a pair of scissors-as a weapon to fight the shooter. This is an improvement on standard active shooter training. Gallo says, which typically teachers people to lock themselves in place and hide. The "lock down" method is often ineffective, he says, and has resulted in many deaths in recent years. In the training's basic level, no one gets killed. But as the trainings become more advanced, players who make a wrong choice be shot. There's no blood; the screen simply turns black slowly. If this sounds terrifying, that's the point, says Gallo. There are plenty of training programs to teach employees how to deal with workplace violence, sometimes involving role play with toy guns. But these trainings are basically games. Gallo says, with employees relaxed and even enjoying themselves. To teach people what they really need to know for an active shooter situation, they need to be scared. "SurviVR will take the fear and turn it into confidence." Gallo says. Question: What is the suggested response in the standard active shooter training? - Fighting the shooter - Running for the exit - Using a computer as a weapon - Locking down
Locking down

Read the following article and select the best answer. Article: MOOCs (Massive Open Online Courses) are free, but without tutoring, and are open to anyone, anywhere in the world. The courses are flexible -- normally three to five hours of study a week -- done at any time, short (5 to 10 weeks) and video-rich. They are also heavily dependent on crowd sourcing: you can discuss a course with fellow students through online forums, discussion boards and peer review. Students don't have to finish the courses, pass assessments or do assignments, but, if they do, they get a certification of participation. The Open University launched FutureLearn, the UK's answer to US platforms such as Coursera, EdX and Udacity, which have been offering MOOCs from top US universities for the past two years. The response has been incredible, with more than three million people registering worldwide. Meanwhile, in 2012, Edinburgh University became the first non-US institution to join Coursera's partnership, comprising 13 universities. "We already run 50 online master's degrees, so this was a logical expansion," says Professor Jeff Haywood, Edinburgh's vice-principal. "It's an investment in teaching methods research. How am I going to teach introductory philosophy to 100,000 people? That's what I call educational R&D." He adds "If you look ahead 10 years, you'd expect all students graduating to have taken some online courses, so you've got to research that. Our MOOCs are no more in competition with our degrees than a lifelong learning course because they don't carry credits." Cooperation is key, Haywood stresses. It is far better to offer 20-30 courses in your own areas of expertise and let other institutions do likewise. Professor Mike Sharples, FutureLearn's academic lead, goes further: "We've tied the elements available before into a package of courses offered by leading universities worldwide on a new software platform, with a new way of promoting it and also a new social-learning teaching method. You won't just receive an exam, but be able to discuss and mark each other's assignments." Bath...
