Q: Article: There was once a spider that lived in a cornfield . She liked this home and planned to stay there for the rest of her life. One day, the spider caught a little bug in her web. Just as the spider was about to eat him, the bug said: "If you let me go, I will tell you something important that can save your life." The spider thought for a little while and listened. "You'd better get out of this cornfield," the little bug said. "The harvest is coming!" "I think you are just telling me a story," the spider said with a smile. "Oh no, it is true," the little bug said. "All the stalks will be knocked down, and the corn will be gathered up. You will be killed by the giant machines if you stay here." "I don't believe you," the spider said as she ate the little bug for lunch. A few days later, the spider was laughing about the story the little bug had told her. She thought to herself: "A harvest! What a silly idea. I have lived here all of my life, and nothing has ever disturbed me." The next day was a beautiful sunny day. The sky above was clear, and there was no wind at all. That afternoon, as the spider was about to take a nap , she noticed some thick dusty clouds moving towards her. She could hear the noise of a great engine , and she said to herself: "I wonder what that could be?" Question: Which might be the best title of the story? Yes or no, is the answer "A stupid spider"?

Question: Article: Most students in China have their own school rules. So do the schools in other countries. Japan: Most schools demand that students wear uniforms, such as sports suits or skirts. They also demand that girls' white socks be folded in a certain way and boys' heads be shaved Other Japanese schools tell students that they may not date, go to movies, leave home after sunset or play video games without permission from school. USA: For safety at home USA schools, students must have a pair of indoor shoes to change into at school every day. This makes sure students won't fall over on the slippery floors and keeps the schools clean. Gum chewing is not allowed in many USA school buildings, as it is difficult to clean up. And if students chew gum in class, they may not focus on study. UK: Strange hairstyles are not allowed in some British schools. But they might allow students to wear certain hairstyles during the World Cup years. Two students had a special design shaved into their hair during 2002 World Cup. But they were not accepted by their school after that because the school said the rules changed since then. Question: British students could have a special hairstyle_. Yes or no, is the answer "only during the World Cup"?
Answer: No

Article: Dear Fang, How are you these days? I have been in England for two months. It's not a long time for a newcomer, and there are still a lot of things to do. Sorry for not being able to write to you soon. London is an old but beautiful city. There are lots of places of interest to visit. Last weekend I went along Thames River with some friends from Japan, Korea and some other countries. The modern skyscrapers among the old buildings impressed(...) us deeply. The classes started two weeks after I arrived here alone. Besides the language, I'm trying to learn about the culture as well. British people are quite different from the Chinese. Do you know the people here do not shake hands as much as we do in China? And it's never a good habit to make noise when you eat. They think it's impolite. There is so much to say, but I have to stop. I will write to you soon again. Love, Harry Question: Harry has studied in London _ . Yes or no, is the answer "for about two months"?
**Answer**
No
