EL 35. 這位老師很生氣,Hugo 沒勞化 36. 雖然這塊牛排看起來像塊岩石 Dear Ms. Louise, Today was my precious little girl's first day in high school. She was thrilled that she would finally meet her new classmates. But when she woke up, she found that she had a big red pimple on her nose! She worried about it so much that she told me she didn't want to go to school. I knew that she felt embarrassed about having a big red zit on her face, especially when she was about to meet new friends and wanted to leave a good impression on them. However, as a mother, I just couldn't let her skip the first day of school. So, I made her go to school this morning. Did I do the right thing? Worried Mother Dear Worried Mother, I think you made the correct decision. Though her concern of making a bad impression on her new friends is understandable, she needs to learn that most people focus only on their own problems and don't even notice others'. Her friends would probably not notice her pimple at all. I think she will gradually figure this out. Don't worry. Talk to her as usual. She must have plenty of exciting stories about her new friends to share with you tonight. Ms. Louise ) 29. What does Ms. Louise do? (3%) A (A) She is a column writer who gives advice and suggestions.

OW dyainst factories that cause pollution. 閱讀測驗3 But the universal of our climate message of crisis wareness hing a fever pitch across the with increasing urgency, a pparent every day. For the Vandana Shiva will never forget a lesson she learned at the age of 13. Her parents insisted that she should wear clothing made only of homespun cotton. One day, Vandana, having returned from a boarding school to her home, demanded a nylon dress, the fashion followed by her rich friends. Her mother agreed. “If that is what you want, of course you shall have it,” she said. “But remember, your nylon dress will help a rich man buy a bigger car. And the cotton that you wear will buy a poor family at least one meal.” Did she buy the nylon dress? Of course not! Maybe this experience led to her resolution to fight for social justice in her later years. Now 60, ever visiting Taiwan in 2010, Vandana's main concern these days is how to preserve Indian traditional crops. This is severely attacked by many global companies. They encourage farmers to grow so-called high-yielding crops; many farmers, therefore, turn to high-tech methods and depend on bioengineered seeds, chemical fertilizers and pesticides. As a result, hundreds of traditional crops are disappearing. Contrary to expectation, high-tech agriculture can not rescue Indians from starvation. Bioengineered seeds are expensive and cannot adapt to local conditions. Hundreds of Indian farmers have committed suicide during the past five he world ironment. ns in 1970. years because of failed harvests. But there is hope. Many farmers are returning to traditional methods promoted by Navdanya, an organization based in New Delhi that Vandana helped found 20 years ago. Navdanya encourages farmers to produce native varieties of crops that can be grown with natural fertilizer and no artificial chemicals. It also helps local farmers form their own self-supporting organization and seed bank. nean? +明一 生能但奇 63
