Article: As they migrate , butterflies and moths choose the winds they want to fly with, and they change their body positions if they start floating in the wrong direction. This new finding suggests that insects may employ some of the same methods that birds use for traveling long distances. Scientists have long thought that insects were simply at the mercy of the wind. Fascinating as their skills of flight are, migrating behavior has been difficult to study in insects because many long distant trips happen thousands of feet above ground. Only recently have scientists developed technologies that can detect such little creatures at such great heights. To their surprise, though, the insects weren't passive travelers on the winds. In autumn, for example, most light winds blew from the east, but the insects somehow sought out ones that carried them south and they positioned themselves to navigate directly to their wintering homes. Even in the spring, when most winds flowed northward, the insects didn't always go with the flow. If breezes weren't blowing in the exact direction they wanted to go, the insects changed their body positions to compensate . Many migrating birds do the same thing. The study also found, butterflies and moths actively flew within the air streams that pushed them along. By adding flight speeds to wind speeds, the scientists calculated that butterflies and moths can travel as fast as 100 kilometers an hour. The findings may have real-world applications. With climate warming, migrating insects are growing in number. Knowing how and when these pests move could help when farmers decide when to spray their crops. Question: Scientists originally thought that _ . Yes or no, is the answer "insects were just blown about by the wind"?
No

Article: London, the capital of England, is political, economic and commercial centre. It stands on the Thames, extending for nearly thirty miles from north to south and for nearly thirty miles from east to west. London is divided into many administrative units. Greater London, the largest unit, cover 1,605 square miles. The heart of this unit is the City of London. It is surrounded by a ring of 12 boroughs called Inner London or Central London, covering 303 square miles, and itself, is again surrounded by a greater ring of 20 boroughs called Outer London with an area of 1,279 square miles. Thus, Greater London is made up of the City and 32 boroughs. Question: From this article, we can see that London _ . Yes or no, is the answer "includes the City, 32 boroughs and some other units."?
No

Q: Article: Having spent two and a half years in China over several visits, I don't remember ever going through a phase we in the United States call "cultural shock". This period of difficulty in adjusting to a new culture would probably have set in during my semester at Peking University. Of course, this is not to say that I didn't notice any differences between the American and Chinese cultures upon my arrival at Peking University, I did notice the differences. Looking back, I remember one of the first differences I noticed: Chinese universities are surrounded by walls. To an American, this is one of the most striking aspects of a Chinese university which immediately sets it apart from an American campus. Having grown up in the United States, I had never seen a university surrounded by high, cement walls. My idea of a university, based on having seen scores of them in different states of the U.S., was a place of life and learning, an inseparable part of the community in which it was located, open not only to the students of the school itself, but also fully accessible to students from other schools and to the broader public. My idea of a university was that it was a center of cultural life, a resource for the entire community. In all my twenty-one years, it had never occurred to me that a school would have a wall around it. Walls enclose and separate; schools expand and integrate . _ I asked a Chinese friend if all Chinese universities have walls around them. "You know, I have never really thought about it. I guess so. I guess all Chinese schools have walls around them, not just universities." "Why?" I asked, "What's the point?" "I don't know. To protect us, I suppose." "From whom?" "I don't know. Don't you have walls around your schools in the United States?" I thought carefully before answering. "No, I've never seen or heard of a university encircled by a wall." My Chinese friend seemed puzzled. Walls around schools came to strike me as more than just an architectural difference between the United States and China.... Question: We can infer from the passage that the author thinks _ . Yes or no, is the answer "walls around the universities are inappropriate in an open China"?
A: No

Article: The iPhone, the iPad, each of Apple's products sounds cool and has become a fashion. Apple has cleverly taken advantage of the power of the letter "i" -- and many other brands are following suit. The BBC's iPlayer -- which allows Web users to watch TV programs on the Internet -- adopted the title in 2008. A lovely bear -- popular in the US and UK -- that plays music and video is called "iTeddy". A slimmed-down version of London's Independent newspaper was launched last week under the name "i". In general, single-letter prefixes have been popular since the 1990s, when terms such as e-mail and e-commerce first came into use. Most "i" products are targeted at young people and considering the major readers of Independent's "i", it's no surprise that they've selected this fashionable name. But it's hard to see what's so special about the letter "i". Why not use "a", "b", or "c" instead? According to Tony Thorne, head of the Language Center at King's College, London, "i" works because its meaning has become ambiguous. When Apple uses "i", no one knows whether it means Internet, information, individual or interactive, Thorne told BBC Magazines. "Even when Apple created the iPod, it seems it didn't have one clear definition," he says. "However, thanks to Apple, the term is now associated with portability ."adds Thorne. Clearly the letter "i" also agrees with the idea that the Western World is centered on the individual. Each person believes they have their own needs, and we love personalized products for this reason. Along with "Google" and "blog", readers of BBC Magazines voted "i" as one of the top 20 words that have come to define the last decade. But as history shows, people grow tired of fads . From the 1900s to 1990s, products with "2000" in their names became fashionable as the year was associated with all things advanced and modern. However, as we entered the new century, the trend eventually disappeared. Question: Nowadays, the "i" term often reminds people of the products which are _ . Yes or no, is the answer "portable"?
No
