在撰写关于环保的雅思作文时，开头部分应该引起读者的注意，并简要介绍文章的主题。以下是一些建议的开头方式：

1. 引用名言或描述：

```

"As we know, 'every little bit helps.' So, it is imperative that we, as individuals, take responsibility for our environmental impact."

```

2. 描述环境问题的现状：

```

"Environmental degradation is a pressing issue that has far-reaching consequences for our planet. It is a topic that requires immediate attention and action."

```

3. 提出问题或引起共鸣：

```

"Have you ever thought about the impact of our daily choices on the environment？ From the food we eat to the way we dispose of waste, every action counts."

```

4. 强调个人责任：

```

"It is often said that 'the environment starts with me.' This statement rings true in a world where individual actions can have a collective impact."

```

5. 引入故事或个人经历：

```

"I remember as a child, the clear streams and lush green trees were a common sight. Today, those scenes are becoming a rarity, replaced by pollution and deforestation."

```

选择适合你文章内容和风格的开头，可以有效地吸引读者的注意力，并为你的论点设定基调。记得保持开头与整篇文章的主题一致，并逐步展开你的观点
