For example, the sex of baby painted turtles is linked to the average temperature in July. Scientists say even small temperature increases can threaten the production of male turtles. In Europe, scientists say warmer temperatures are affecting the spring and autumn seasons.

One reason for the success of fast fashion is the rise of the social media. A report by the investment research firm Bernstein found that Millennials—people born in the 1980s and 90s—wanted to wear a variety of clothes in the photos they posted on social media. As a result, many businesses which offer trendy and low-cost clothes are growing.But the situation is changing now. Maxine, a woman in her early thirties, looks in her closet full of clothes, but she has nothing to wear. She says she hates always shopping for what is in style. Instead, she wants to buy fewer clothes that she can wear o ver and over. “Other people want the same thing,” she says.So Maxine and a business partner, Soraya, started a “slow fashion” clothing company called Zady. “Slowfashion” means clothes that last a long time. They often feature classic colours and shapes,and are made from natural materials.The terms “fast fashion” and “slow fashion” are related to “fast food ” and “slow food”: fast food is still popular in the US, but many restaurants increasingly offer high-quality, more expensive and relaxed meals.Like slow food, slow fashion also aims to use sources that are good for the environment and workers. Maxine says people in her generation want to know where their clothes come from and who is making them. To answer Millennials’ demand for information about the products they buy, Ms Maxine’s company, Zady, includes details about the history of the brands. It also describes the process in which the clothes are made. Maxine says Zady aims to tell shoppers where their clothes come from, where they go, and how they impact the world.The international business H&M is answering Millennials’ demands in another way. It has created a recycling programme for clothes. Shoppers who bring clothes they no longer want to H&M stores can receive a discount on new things they buy. An H&M spokesman says, “We have a clear vision to avoid and minimize waste that goes into landfills.”1. About Millennials, which of the following statements is NOT TRUE?A. Most of them are in their twenties or thirties.B. They are crazy about fashionable and cheap clothes.C. They contributed a lot to the rise of fast fashion.D.

What can we learn about the programme of H&M in the last paragraph?A. It can benefit the environment.B. The company only sells clothes made of recycling materials.C.

Unit 4 Global warming教学目标1) Learn some knowledge about the greenhouse effect and global warming.2) Know the contents of the text well by talking about this topic and reading.3) Discuss the problem of global warming and express your own opinions学情分析There are two meanings of the term "greenhouse effect". There is a "natural" greenhouse effect that keeps the Earth's climate warm and habitable(suitable for people to live in). Without it, scientists estimate that the average temperature on Earth would be colder by about 30 degrees Celsius (54 degrees Fahrenheit), far too cold to sustain(维持) our current ecosystem. In other words，the normal greenhouse effect is a natural process which is to some degree beneficial to us.重点难点Master the main idea of the first five paragraphs by talking about the topic.教学过程活动1 【讲授】Unit 4Teaching procedures:Step I. GreetingsGreet the whole class as usual.Step II. Lead-inLead to the topic by showing an article to the students and let students know about two types of greenhouse effect ("natural" greenhouse effect and “man-made” greenhouse effect) and their exact meanings.Step III. Analyze two graphs to learn the main idea of the first five paragraphs.From the first graph, we can see that during the 20th century the temperature of the earth rose about one degree Fahrenheit. All scientists agree with the view that the increase in the earth’s temperature is due to the burning of fossil fuels like coal, natural gas and oil to produce energy.More such burning means more carbon dioxide added to the atmosphere.We can see clearly that the levels of carbon dioxide have increased greatly over the past decades.Higher levels of carbon dioxide means sharper increase of the temperature. The phenomenon is called global warming.There has been a debate towards global warming over the pastyears. Opinions about it vary from person to person.Step IV. Read the whole passage to review the main idea of the first five paragraphs and know the two different opinions. Dr. FosterCarbon dioxide has caused the global temperature to ________. An increase of five degrees would be a ____________ and could be very ________.Possible results: __________________(海平面上升)___________________(洪灾)___________________(恶劣的风暴)___________________(干旱)__________________(饥荒)__________________(疾病的传播)___________________________(物种的消失)George Hambley:Any warming will be ______ with few bad ______________________. More carbon dioxide is a _________ thing, which makes crops __________ more and will encourage _____________________.Step V. Discuss the statement: We should take immediate action about global warming.Requirement: Write down your reasons and possible measures on your learning sheetStep VI. Presentation.Ask some students to read their reasons and possible reasons loudly to the whole class.Step VII. Assignment.Make up a complete composition in groups.
