[EX Q]: Article: Students often want to practice their English outside class. One of the best ways to practice your English is to speak to a foreigner. You may ask, "Is it okay to try to talk to foreigners I see in the street?" The answer is yes and no, but probably no! If you see a foreigner who looks lost, it is polite to ask him, "May I help you?" But, otherwise, you should probably let them get on with their business. Situations, however, do exist where it is quite all right to talk to foreigners. If a foreigner enters your school, classroom, office, shop or restaurant, for instance, feel free to ask him (for example): -- What is your name? -- Where do you come from? -- What do you think of Beijing? -- How long will you stay in Beijing? There are also situations where it's okay to talk to foreigners in public places. If you see a foreigner alone in a restaurant, bar or coffee shop, it may be appropriate to ask him or her: -- Is this seat free? -- Do you mind if I talk to you in English? You can probably help them if they are new in China and if they are alone, you may be able to make them feel more welcome. After a few such questions, you should know whether this person wants to talk to you or not. If they ask you similar questions, or if they give long, informative answers, you're in luck. If not, then give them their privacy. Talking to strangers is fun if you choose the right time and place.

[EX Q]: Article: According to the US government, wind farms off the Pacific coast could produce 900 gigawatts of electricity every year.Unfortunately, the water there is far too deep for even the tallest windmills to touch bottom.An experiment under way off the coast of Norway, however, could help put them anywhere. The project, called Hywind, is the world's first large-scale deepwater wind turbine  .Although it uses a fairly standard 152-ton, 2.3-megawatt turbine, Hywind represents totally new technology.The turbine will be fixed 213 feet above the water on a floating spar, a technology Hywind's creator, the Norwegian company StatoilHydro, has developed recently.The steel spar, which is filled with stones and goes 328 feet below the sea surface, will be tied to the ocean floor by three cables ; these will keep the spar stable and prevent the turbine from moving up and down in the waves.Hywind's stability in the cold and rough sea would prove that even the deepest corners of the ocean are suitable for wind power.If all goes according to the plan, the turbine will start producing electricity six miles off the coast of southwestern Norway as early as September. To produce electricity on a large scale, a commercial wind farm will have to use bigger turbines than Hywind does, but it's difficult enough to balance such a large turbine so high on a floating spar in the middle of the ocean.To make that turbine heavier, the whole spar's center of gravity must be moved much closer to the ocean's surface.To do that, the company plans to design a new kind of wind turbine, one whose gearbox   sits at sea level rather than behind the blades. Hywind is a test run, but the benefits for perfecting floating wind-farm technology could be extremely large.Out at sea, the wind is often stronger and steadier than close to shore, where all existing offshore windmills are planted.Deep-sea farms are invisible from land, which helps overcome the windmill-as-eyesore objection.If the technology catches on, it will open up vast areas of the planet's surface to one of the best low-carbon power sources available. 
 Question: The Hywind project uses totally new technology to ensure the stability of  _  . 
 Options: (A) the cables which tie the spar to the ocean floor (B) the spar which is floating in deep-sea water (C) the blades driven by strong and steady sea wind (D) the stones filled in the spar below the sea surface 
 Asnwer: C
[EX A]: No

[EX Q]: Article: I do desire to help my Chinese students to find a better way of learning. I once divided my Chinese MBA students into six groups and set them an assignment: brainstorming on "two-hour business plans", for example: a restaurant chain. Originality would be valued most. As a result, five groups proposed projects for restaurant chains. The sixth showed a catering service. I couldn't help expressing my disappointment, though the time limit had been rather challenging. Those middle managers and financial analysts from state-owned enterprises and global companies were not untalented or without opinions, but they had been accustomed to an educational system that rarely rewarded critical thinking or Originality. Papers were often copied from the Internet and the Harvard Business Review. Students insisted that copying was a superior business strategy, better than inventing and creating. In China, you can see almost all kinds of products you can imagine have been made and sold, but so few well developed marketing and management minds have been produced that it will be a long time before most people in the world can name a Chinese brand! Partnerships with institutions like Yale and MIT have been established so as to solve the problem mentioned above. And there's also the "thousand talent scheme": this new government program is designed to improve technological modernization by inviting top foreign trained scientists to the mainland with large sums of money. But there are concerns about China's research environment, which is known for lacking in encouraging independent thinking and inventiveness, and even high salary offers may not be attractive enough to overcome this. If China wants to become a major world creator, it is no good just seeking partnerships with top Western universities or gathering a group of well-educated people and telling them to think creatively. It's time to establish a rich learning environment for young minds. Yes, new way of learning is the key! 
 Question: The author feels disappointed when the students hand in their plans because  _
