Q: Article: Alibaba started taking the lead in China, simply enough, by connecting big Chinese manufacturers with big buyers across the world. Its business-to-business site, Alibaba.com allowed business to buy almost everything. Alibaba's advantage wasn't hard to identify: size. Alibaba is just big, even by Chinese standards. Its marketplaces attract 231 million active buyers, 8 million sellers, 11.3 billion orders a year--and _ It encourages people to use its markets--not charging small sellers a percentage of the sale. If you want a quick look into the influence of Alibaba on daily Chinese life, take my experience. I moved to Beijing almost a year ago and quickly got tired of visiting small stores across the crowded, polluted city of 20 million people in search of new electronics, bathroom furnishings, and anything else my wife wanted. "You're looking for what exactly? Why not try _ ? " my Chinese teacher asked me one day. With that, my wonderful new relationship with Alibaba began. Alibaba's original business-to-business model now is secondary to consumer buying. Chinese retail buying makes up 80% of Alibaba's profit, and leading that group is Taobao, with 800 million items for sale and the most unbelievable selection of things you'll ever find. TMall.com is Alibaba's other big site, where you can find brand name goods from Nike and Unilever near the lowest prices. What I have a hard time explaining to friends and family back in the U.S. is how China has gone beyond traditional shopping--big-box retailers especially --in favor of online purchases on Taobao and a few other sites. In smaller towns than Beijing, where big retailers have not yet traveled, shopping online is shopping, and shopping is Taobao. I have a list of some of my recent purchases on Taobao for a sense of how extensive the marketplace is. Almost everything arrived a day or two after ordering with free shipping. I'm not even a big buyer, because I need friends to help me search the Chinese-language site. When I was searching my purchase history on my Chinese teacher's iPad, which helps me buy goods, I looked through with great difficulty about 10 of her purchases for every one of mine.

 Options: (A) its big size (B) its business-to-business service (C) its not charging small sellers (D) its low price

Q: Article: In summer, millions of people will head for the beach.And while the ocean can be a great place to swim and play, it may also be useful in another way.Some scientists think that waves could help make electricity. "Have you ever been on a surfboard or boat and felt yourself being lifted up by a wave? Or have you jumped in the water and felt the energy as waves crashed over you?" asked Jamie Taylor of the Wave Energy Group at the University of Edinburgh in Scotland."There is certainly a lot of energy in waves." Scientists are working on using that energy to make electricity. Most waves are created when winds blow across the ocean."The winds start out by making little ripples   in the water, but if they keep on blowing , those ripples get bigger and bigger and turn into waves, "Taylor said."Waves are one of nature's ways of picking up energy and then sending it off on a journey." When waves come towards the shore, people can set up dams or other barricades to block the water and send it through a large wheel called a turbine   .The turbine can then power an electrical generator   . The United States and a few other countries have started doing research on wave energy , and it is already being used in Scotland. The resource is huge.We will never run out of wave power, besides, wave energy does not create the same pollution as other energy sources, such as oil and coal. Oceans cover three quarters of the earth's surface.That would make wave power seem perfect for creating energy around the world.There are some _ , however. Jamie Taylor said that wave power still cost too much money.He said that its effects on animals in the sea were still unknown.Plus, wave power would get in the way of fishing and boat traffic. With more research, however, "many of these problems might be overcome," Taylor said."Demand for energy to power our TVs and computers, drive our cars, and heat and cool our homes is growing quickly throughout the world.Finding more energy sources is very important, for traditional sources of energy like oil and gas may run out some day." In the future, when you turn on a light switch, an ocean wave could be providing the electricity! 
 Question: Which of the following is NOT true? 
 Options: (A) Wave power costs too much money. (B) Wave energy creates the same amount of pollution as other energy sources. (C) Wave power affects fishing and boat traffic. (D) Wave power may affect marine animals. 
 Asnwer: C
