Unit 3　Environmental Protection The Road to Destruction We know that cars are bad for us.But we all make excuses，“The buses are terrible”；“The trains are always late”；“I haven't got time to walk”．I'm talking about myself，too.To be frank，I'm addicted1 to my car.When I asked Jenny Trowe of Greenpeace for advice about how to give up，she told me five things： ·Use your legs.In 2014，over 55% of car journeys were under eight kilometres.Instead of taking short car journeys，we could easily walk or cycle.Leg power can save your money，keep you fit and help you live longer.Regular exercise also cuts the risk2 of heart disease by 50%! ·Use public transport.Up to 90 people can travel in one bus，while the same number will need at least 18 cars.Sometimes it can take a little bit longer，but so what？You can relax，read a book，talk to someone—who knows? ·Think before you go.Do you really have to go to that shopping centre on the other side of town？What about the shops around the corner？Before you get into your car，think about whether you really need to make that journey. ·Share cars.If you really have to use a car，share journeys with someone else.It is much cheaper and kinder to the environment. ·Take action！We often think there is nothing we can do about the noise，pollution and danger of traffic.There is.If your street is full of heavy traffic，talk to your neighbours about it.Write to the papers.Go to the city government.Ask for a speed limit3.Do whichever of these things that suit you.Don't just sit around and complain4! All quite simple，isn't it？Five easy ways to improve our environment.Well，I'm sorry I have to finish this article，but I've got to pick up my daughter from school at 4 pm.Then I've got to drive to the supermarket to do the shopping.After that，I have to take my son to a party.The traffic is going to be horrible5，but what can I do?

Step 1　Pre-reading 1．Look at the pictures and tell us what is happening. 2．What other environmental problems do you know? ①River_pollution. ②Noise_pollution. ③Rubbish_carelessly_disposed. ④Energy_exhaustion.

D．The heat from the sun. 答案：B 2．Where does this article most probably come from? A．A magazine.　　　 B．A handbook. C．An advertisement. D．A notice. 答案：A Ⅳ.Sentence Explanation 1．There is little doubt that Earth is getting warmer and warmer. 分析：句中There is little doubt that...是固定句式，意为“毫无疑问……”； that引导的是同位语从句，补充说明doubt的内容。 句意：毫无疑问，地球变得越来越暖和了。 2．It is our responsibility to seize every opportunity to educate everyone about global warming，along with its causes and impacts，because this is the most serious issue affecting all of us on this planet. 分析：句中It是形式主语，真正的主语是后面的动词不定式短语； because引导的是原因状语从句，从句中affecting all of us on this planet是现在分词短语作定语。 句意：我们有责任抓住每一个机会，让每个人了解全球变暖及其原因和影响，因为这是影响地球上我们所有人的最严重的问题。 Step 3　Post-reading Read the text and try to retell it. As we know，global warming is affecting our Earth 1.seriously(serious)．What is causing the increase in the global surface temperature？Everyone believes greenhouse effect is the main reason 2.for global warming.In the atmosphere there are some greenhouse gases 3.keeping(keep) Earth's climate warm.This is the natural greenhouse effect，4.which helps Earth sustain life.However，people produce 5.a huge amount of extra greenhouse gases by burning fossil fuels.Such gases can trap 6.more(much) heat energy in the atmosphere and make Earth warmer.This 7.is_called(call) man-made greenhouse effect.Global warming has led to an increase in extreme weather and 8.natural(nature)disasters worldwide，such as rainstorms and heat-waves causing many 9.deaths(die)and economic losses.Therefore，governments should take action and measures 10.to_reduce(reduce)greenhouse gas emissions.And we as individuals must do our best to change our lifestyles to reduce our “carbon footprint”． In recent years some extreme weather events have arisen from global warming because of human activities，with studies indicating an increasing threat from extreme weather in the future.Scientists were certain that global warming is being caused mostly by increasing concentrations of greenhouse gases and other human activities. Its effects include warming global temperature，rising sea levels and expansion of deserts in the subtropics (亚热带)．Warming is expected to be greater over land than over the oceans and greatest in the Arctic，with the continuing loss of glaciers，permafrost and sea ice.Other likely changes include more frequent extreme weather events including heat waves，droughts，heavy rainfall with floods，heavy snowfall and species extinction due to great change of temperature.Bad effects on humans include the threat to food security from decreasing crop yields and the loss of populated (有人口居住的) areas because of rising sea levels. Possible responses to global warming are reduction of emissions，adaptation to its effects，building systems resilient to its effects，and possible future climate engineering.Most countries are parties to the United Nations Framework Convention on Climate Change (UNFCCC)，whose objective is to prevent dangerous climate change.It has adopted a range of policies designed to reduce greenhouse gas emissions and to assist in adaptation to global warming.It is agreed that future global warming should be limited to below 2.0 ℃ (3.6 ) relative to the pre-industrial level. On 12 November 2015，NASA scientists reported that human-made carbon dioxide continues to increase above levels that have not been seen in hundreds of thousands of years：currently，about half of the carbon dioxide released from the burning of fossil fuels remains in the atmosphere and is not absorbed by vegetation and the oceans. 【语篇解读】　本文讲述了温室效应带来的影响， 我们应该适应， 并且要减少温室气体的排放以免它的加剧。 1．What does the underlined word“resilient”mean?
