雅思写作技巧
词汇替换提升Lexical Resource
避免重复使用简单词汇,
- Important → Crucial / Pivotal
- Change → Transform / Revolutionize
- Use → Utilize / Deploy
例句对比:
- 普通表达:"Technology is important for society."
- 高级表达:"Technology plays a pivotal role in societal advancement."
数据引用增强论证力
在议论文中,引用权威数据可增强说服力。
"A study by McKinsey (2023) reveals that 70% of companies adopting AI report increased productivity."
平衡利弊分析 常要求讨论利弊,可采用以下结构:
- Advantages: Efficiency, accessibility, innovation.
- Disadvantages: Job displacement, privacy concerns.
例句:
"While automation boosts efficiency, it also raises concerns about unemployment in traditional sectors."
避免绝对化表达
使用may / might / could而非will,体现严谨性。
- 绝对化:"AI will replace all jobs."
- 严谨表达:"AI could potentially displace certain manual jobs."
常见科技类雅思题目
- "Some believe AI will improve human lives, while others argue it poses risks. Discuss both views."
- "The advantages of renewable energy outweigh the disadvantages. To what extent do you agree?"
- "5G technology will transform communication. Do you agree or disagree?"
在备考时,可针对这些题目练习,结合上述词汇和数据,构建高分答案。
