【简答题】
Imagine this: your parents go away on business, but you have to stay at home alone. Would life be as easy as when your parents are around? Would it be a perfect holiday for you? “I can fill an empty stomach with tomato and egg soup, but that's all. I think many of my classmates are the same. We wouldn't know what to do, or how to look after ourselves,' said Zheng Chenyu. 'And I'd forget something important. I'd probably watch television and burn the soup. ' “As soon as I leave home, I'll learn to cook. But now parents do almost everything for us. We’re very lazy, 'she said. Most teenagers have only time for their homework. They don't learn any life skills until they go to college. However, Sima Yige doesn't think so. “I think I'd be all right. I wouldn't just eat sandwiches or fruit. I know how to cook, some sim­ple dishes because my mum showed me,' the 13 - year - old boy said. In his opinion, many teen­agers depend too much on their parents, and there is much more to learn than cooking, like 'tidying up your room or even dressing yourself properly.' For most teenagers it wouldn't be a holiday at all. 小题1:Why would Zheng Chenyu probably burn the soup? ________________________________________ 小题2:When will Zheng Chenyu learn to cook? ________________________________________ 小题3:Translate the underlined sentence 'They don't learn any life skills until they go to college.
