Unit 4 单元话题写作指导 【单元话题分析】 本单元的话题为“地球（The Earth）”，核心围绕“我们为什么要了解地球”展开。写作时，需运用本单元重点的“there be”句型（描述地球存在的资源、问题等），结合一般现在时（阐述地球的常规特征与当前面临的问题），从“地球的神奇之处” “地球面临的困境” “保护地球的行动”三个维度组织内容。同时，可融入具体事例（如塞罕坝治沙、海洋塑料污染），用形容词（如amazing、harmful）增强描述感染力，清晰传递“保护地球”的核心观点。 【单元写作指导】 话题词汇必备 【单词】 Earth 地球 planet 行星 ocean 海洋 forest 森林 desert 沙漠 pollution 污染 plastic 塑料 protect 保护 resource 资源 energy 能源 harmful 有害的 recycle 回收利用 explore 探索 provide 提供 survive 生存 【短语】 solar system 太阳系 sea level 海平面 plastic pollution 塑料污染 air pollution 空气污染 water pollution 水污染 cut down trees 砍伐树木 protect the Earth 保护地球 recycle waste 回收垃圾 use less plastic 减少塑料使用 provide ... with ... 为……提供…… Beach Clean-up Day 海滩清洁日 take care of the Earth 呵护地球 话题句子必备 The Earth is an amazing planet—it has high mountains, deep oceans, green forests and wide deserts. 地球是一颗神奇的行星———它有高耸的山脉、深邃的海洋、绿色的森林和广阔的沙漠。 There is about 70% water on the Earth’s surface, but most of it is salt water in the oceans. 地球表面约70%是水，但大部分是海洋中的盐水。 The Earth provides us with everything we need, such as food, water, air and energy. 地球为我们提供了所需的一切，比如食物、水、空气和能源。 There is more and more plastic pollution in the sea—many sea animals get ill or die because they eat plastic. 海洋中的塑料污染越来越严重———许多海洋动物因为误食塑料而生病或死亡。 We can protect the Earth by planting trees, using cloth bags instead of plastic bags, and recycling waste. 我们可以通过种树、用布袋代替塑料袋、回收垃圾来保护地球。 Saihanba used to be a desert, but now it’s the world’s biggest man-made forest—this shows we can change the Earth for the better. 塞罕坝曾经是一片沙漠，但现在是世界上最大的人工森林———这说明我们可以让地球变得更好。 【话题范文必背】 Protect Our Only Home—the Earth The Earth is our only home in the solar system.

But we can do something to help. My class held a “Beach Clean-up Day” last weekend. We picked up plastic bottles and bags from the beach, and told visitors to use less plastic. At home, I now save water by turning off the tap when I brush my teeth. My parents also start to recycle paper and glass. The Earth is precious.
