Starting out是导入部分，包括观察图片回答问题和观看视频回答问题两个环节。通过问答部分将学生的思路引入灾难、突发疾病、自然灾害等话题，将学生迅速带入本单元的话题情境中，为后面的学习热身，做好铺垫。
Understanding ideas部分首先展示了一些野生动物的图片，假设在城市里见到这些野生动物会不会很吃惊，将话题直接导人城市里的野生动物这个话题。正文部分分别展开陈述野生动物为什么会出现在城市里，适应了野外生活的它们在城市里会有哪些利弊，它们如何应对。通过该文章的学习，让学生意识到人为原因破坏野生动物的栖息地，打乱了它们固有的生活模式的问题。因此，要保护野生动物，保护它们的栖息地，敬畏自然。

教学过程：
Step I Starting out
1.Look at the pictures and answer the questions.
earthquake Disease outbreak
shipwreck jungle
space Water shortage
·What does each picture show
·What difficulties would people have surviving in these situations
Suggested answers： ·The first picture shows that an earthquake has happened. The road is cut off. The second picture tells us that a disease has broken out and is probably spreading. In the third picture, we can see a ship sinking. The fourth picture shows us a dense jungle In the fifth picture, we can see an astronaut in space. The sixth picture shows us a severe drought. ·Below are the difficulties people would have surviving in each situation. □People would find it difficult to leave the area to fine safety, or to receive supplies such as food, water, medicines and fuel. Power and communications may have been cut off by the earthquake. There is a risk of further quakes via an aftershock □People may face difficulties such as quarantine, shortage of hospital services and panic-buying of essential medicines, food or other supplies. There may be misinformation and panic. □People who are unable to escape the ship on a lifeboat face the immediate dangers of drowning or of dying from exposure. Those who do escape on a lifeboat need to ration their food and water, and hope for rescue as soon as possible. □People would find it difficult to travel and navigate. It would also be difficult to find food and water. Wild animals and venomous insects are also potential problems. □Space is an extreme environment for human beings. They face danger from extreme temperatures, low pressures and radiation. They must carry everything they need with them, even air. The lack of gravity makes simple actions such as eating, drinking, moving and even sleeping difficult. Anyone who spends too long in a zero-gravity environment risks losing bone and muscle mass. □Without water, people and livestock face death within a short period of time. In addition to water shortages, drought causes crop failure, so people would face food shortages as well. This could affect people who do not live in the drought-affected area. Severe food shortages can cause famine, migration collapse of social order and war.
2. Watch the video and answer the questions.
·Where do the people in the video live
·What difficulties do they face How do they overcome those difficulties
·What part of the life there would be most challenging for you Why
Suggested answers: ·The people in the video live in Antarctica. ·People living in Antarctica face a lot of difficulties. □They have to endure extreme weather including freezing temperatures, fierce winds and strong blizzards. When they go outside the stations, they wear special clothes for protection. As weather can change from calm to white-out in minutes, people have to take a special survival bag in case they are trapped outside overnight. □One of the most difficult things is the long days and nights. They may cause issues with the scientists’ body clocks. The darkness also makes outdoor research impossible. □It is almost impossible to grow fresh produce there because of the extreme conditions，and most food is imported. It is difficult for scientists to have a varied diet，and they can’t get enough fresh fruit and vegetables. □They have to face psychological problems. To keep the scientists psychologically healthy, research stations offer activities and entertainment including live music and lectures. ·略
