高中英语人教版选修六Unit4泛读课文逐句翻译选修六Unit4 WHAT CAN WE DO ABOUT GLOBAL WARMING?关于全球变暖，我们能干些什么呢？Dear Earth Care, 亲爱的“关爱地球”组织：I am doing a project on behalf of my school about global warming. 我正代表学校做一项关于全球变暖的课题研究。
Sometimes I feel that individuals can have little effect on such huge environmental problems. 有时候我觉得，像这样一个巨大的环境问题，个人是起不了什么作用的。
However, I still think people should advocate improvements in the way we use energy today. 然而我仍然认为人们应该支持改善日常能源的消耗方式。
As I'm not sure where to start with my project, 由于我还不清楚我该从哪里着手开始我的研究。
I would appreciate any suggestions you may have. 我希望能得到你们的建议。
Thank you! 谢谢！Ouyang Guang欧阳光Dear Ouyang Guang, 亲爱的欧阳光：There are many people who have a commitment like yours, but they do not believe they have the power to do anything to improve our environment. 有许多人承担你这样的义务，而他们不相信自己有能力来影响环境。
That is not true. 这种想法是不正确的。
高中英语新课标选修6unit4高中英语新课标选修6的Unit 4通常围绕一个特定的主题展开，例如文化、科技、环境等。
由于我没有具体的教材内容，我将提供一个通用的Unit 4教学内容框架，以供参考。
Unit 4: Exploring Cultural DiversitySection 1: Warm-up and Vocabulary- Begin the class with a brief discussion about the importance of cultural diversity.- Introduce new vocabulary related to the theme, such as "heritage," "tradition," "cuisine," "folklore," and "customs."Section 2: Reading Comprehension- Present a reading passage that explores different aspects of cultural diversity, such as festivals, art, and music from various countries.- After reading, ask students to identify the main ideas and supporting details.- Discuss any unfamiliar expressions or idiomatic language used in the text.Section 3: Grammar Focus- Introduce a grammar point relevant to the theme, such ascomparative and superlative adjectives, which can be used to describe cultural differences.- Provide examples and practice exercises for students to complete.Section 4: Listening Practice- Play an audio recording of a conversation or a lecture about cultural exchange programs or experiences.- Have students listen for specific information and answer comprehension questions.Section 5: Speaking Activity- Organize a role-play activity where students take on the roles of cultural ambassadors from different countries, sharing information about their "country's" culture with the class.- Encourage the use of the new vocabulary and grammar structures learned in the previous sections.Section 6: Writing Task- Assign a writing task where students describe a cultural event or tradition from their own or another culture.- Provide a template or outline to guide their writing, focusing on organization and the use of descriptive language.Section 7: Cultural Appreciation- Conclude the unit with a class activity that involvesstudents sharing and appreciating various cultural elements, such as food, music, or clothing.- Encourage reflection on the importance of respecting and understanding different cultures.Section 8: Assessment- Administer a quiz or test to assess students' understanding of the vocabulary, grammar, and reading comprehension skills covered in the unit.Section 9: Homework- Assign homework that reinforces the learning objectives of the unit, such as further reading on a cultural topic, additional grammar exercises, or a short essay on cultural diversity.This framework is designed to be adaptable to the specific content and requirements of the actual textbook or curriculum being used. Adjustments can be made based on the needs and interests of the students.。
The greenhouse effectThe greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (water vapor, carbon dioxide, nitrous oxide, and methane, for example) trap energy from the sun. Without these gases, heat would escape back into space and Earth’s average temperature would be about 60ºF colder. Because ofhow they warm our world, these gases are referred to asgreenhouse gases.Have you ever seen a greenhouse? Most greenhouseslook like a small glass house. Greenhouses are used togrow plants, especially in the winter. Greenhouses work by trapping heat from the sun. The glass panels of the greenhouse let in light but keep heat from escaping. This causes the greenhouse to heat up, much like the inside of a car parked in sunlight, and keeps the plants warm enough to live in the winter.The Earth’s atmosphere is all around us. It is the air that we breathe. Greenhouse gases in the atmosphere behave much like the glass panes in a greenhouse. Sunlight enters the Earth's atmosphere, passing through the blanket of greenhouse gases. As it reaches the Earth's surface, land, water, and biosphere absorb the sunlight’s energy. Once absorbed, this energy is sent back into the atmosphere. Some of the energy passes back into space, but much of it remains trapped in the atmosphere by the greenhouse gases, causing our world to heat up.The greenhouse effect is important. Without the greenhouse effect, the Earth would not be warm enough for humans to live. But if the greenhouse effect bees stronger, it could make the Earth warmer than usual. Even a little extra warming may cause problems for humans, plants, and animals.。

The greenhouse effect
The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (water vapor, carbon dioxide, nitrous oxide, and methane, for example) trap energy from the sun. Without these gases, heat would escape back into space and Earth’s average temperature would be about 60ºF colder. Because of how they warm our world, these gases are referred to as greenhouse gases.
Have you ever seen a greenhouse? Most greenhouses
look like a small glass house. Greenhouses are used to
grow plants, especially in the winter. Greenhouses
work by trapping heat from the sun. The glass panels
of the greenhouse let in light but keep heat from escaping. This causes the greenhouse to heat up, much like the inside of a car parked in sunlight, and keeps the plants warm enough to live in the winter.
The Earth’s atmosphere is all around us. It is the air that we breathe. Greenhouse gases in the atmosphere behave much like the glass panes in a greenhouse. Sunlight enters the Earth's atmosphere, passing through the blanket of greenhouse gases. As it reaches the Earth's surface, land, water, and biosphere absorb the sunlight’s energy. Once absorbed, this energy is sent back into the atmosphere. Some of the energy passes back into space, but much of it remains trapped in the atmosphere by the greenhouse gases, causing our world to heat up.
The greenhouse effect is important. Without the greenhouse effect, the Earth would not be warm enough for humans to live. But if the greenhouse effect becomes stronger, it could make the Earth warmer than usual. Even a little extra warming may cause problems for humans, plants, and animals.。
