It was nice for me to get away from the fog and take a trip to see a food festival. In Gilroy, a warm and sunny town in the US, people celebrate(庆祝) one of the best food festivals —the Gilroy Garlic Festival. Gilroy is famous for its delicious garlic(大蒜) food. This year the festival was great! It was all about food and fun.

There were many kinds of foods and all of them had a garlic flavor. I think the garlic fries were the best. The fries were dark golden in color, with the fresh smell of garlic. The main dish of the festival was garlic ice cream. It was wonderfully sweet. What's more(而且), it was free. There was even garlic chocolate and pizzas. I was surprised that there were so many kinds of garlic foods. The festival was full of surprises. Some even said there were kangaroos and crocodiles(袋鼠和鳄鱼), too. But I don't think it was true. The wonderful garlic flavor makes the Gilroy Garlic Festival a special part of summertime.

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 don’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.”Although Zheng Chenyu believes that basic life skills, such as cooking and washing clothes, are especially important, she doesn’t think teenagers get enough practice. “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.（A）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 mom showed them to me,” the 13-year-old boy said. In his opinion, many teenagers（B）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.
