Article: Robert had just moved into the street and he felt strange that he was not wanted. He knew that perhaps the other boy students were trying to get an idea of what kind of a boy he was. This did not help to make him less lonely. He was new and he had to be tested. Still, proving himself would not be all that easy. He did not want to run with bad boys or get into something against the law to prove that he was strong. No! He must show what he was made of in a more helpful way. That would be better when he got the idea. The next day was Saturday. He knew that most of the boys would be down on the playground and choose up sides for the Saturday game. Robert knew he could play well and that just might be enough to prove he was strong and to make friends with them. He arrived early and did his step exercises. He shot the ball several times and did some other exercises--the most difficult and most wonderful in basketball. Then the boys came. Robert went through what he had done before the game and showed what he could do. No one said a word. The boys just looked at each other and thought about it. In the end, when it was all over, the biggest of the group just smiled and shook his head. Robert knew he had made it.

Article: During the tsunami disaster of 2004, over 300,000 people died. No one has counted the number of animals killed, but we know that it wasn't many. All over the region, before the disaster struck, animals were behaving strangely. Shortly before the tsunami, in Khaolak, Thailand, twelve elephants that were giving tourists rides became agitated. They suddenly left their usual habitat, carrying four surprised Japanese tourists to safety. On the eastern coast of India, flamingos , which should be breeding at this time of year, suddenly flew to higher ground. Of the two thousand wild pigs that live in an Indian nature reserve, only one was found dead after the tsunami. The idea that the animals are able to predict disasters is nothing new. In fact, it has been well-recorded over the years. Twelve hours before Hurricane Charlie hit Florida in 2004, fourteen sharks left their natural habitat and stayed in deep waters for two weeks. The sharks, which were being observed by US scientists, had never done this before. They escaped the hurricane. In the winter of 1975 in Haicheng, China, snakes which would normally have been hibernating were seen on the ground. Days later there was a big earthquake striking. Unlike human beings, wild animals' senses are sharper and they can feel even the smallest changes in the environment. In other words, they see natural warnings that are invisible to the human eye. Ancient people probably had the similar "senses", which they needed to survive, but these have been lost to us as modern technology leads us further away from the danger that nature creates. The real question is, can we use the reactions of animals to save ourselves from natural disasters? Animal behaviour expert, Rupesh Kaneira, believes we have no choice. "The technology which we rely on isn't always perfect, and in poorer countries it isn't even available. Animals know the environment better than any of us. When they run for their lives, we must follow."
Question: The wild animals can predict the natural disasters because they _ .
Options: (A) can run for their lives when natural disasters happen (B) don't even have the modern technology to help them (C) are being observed and tracked for scientific experiments (D) are quick to notice the slightest changes in the environment
Asnwer: A

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.
Question: Alibaba's advantage mainly lies in _ .
Options: (A) its big size (B) its business-to-business service (C) its not charging small sellers (D) its low price
