Unit 4 Global warming导读：很多科学家认为全球变暖是由人类活动造成的，由于人们焚烧化石矿物或砍伐并焚烧森林，产生了二氧化碳等多种温室气体，导致全球气候变暖。

因此，我们究竟应该为此做些什么呢？Task：What can we do to protect the earth from beingbad to worse?Global warming is a growing problem in the world. Melting ice－caps in the Arctic and Antarctica, rising temperatures across the continents, increasing number of typhoons and tropical storms are just some of the effects of global warming.It must be realised that humans activities are the causes of global warming. It is therefore our duty to save the earth. We can begin by minimizing the amount of carbon dioxide by taking public transport instead of driving and using energy －efficient electrical appliances. Besides, the government can probably limitthe number of cars allowed on the roads by imposing fines on offenders and improving public transport systems. More trees can be planted too. Education to protect the environment should also be planned. Countries around the world can hold meetings and conferences and decide the steps to take to limit the CO2 levels. Economic sanctions can also be imposed on countries that have violated the rules. The Kyoto Protocol is one such example.It is important to cure the world, for the sake of ourselves and our descendants. We have to take action now.请根据语义及提示写出单词1.

Unit 4 Global warmingⅠ.阅读理解El Niño，a Spanish term for “the Christ child，” was named by South American fishermen who noticed that the global weather pattern，which happens every two to seven years，reduced the amount of fishes caught around Christmas.El Niño sees warm water，collected over several years in the western Pacific，flow back eastwards when winds that normally blow westwards weaken，or sometimes the other way round.The weather effects，both good and bad，are felt in many places.Rich countries gain more from powerful Niños，on balance，than they lose.A study found that a strong Niño in 1997－98 helped America’s economy grow by 15 billion，partly because of better agricultural harvests：farmers in the Midwest gained from extra rain.The total rise in agricultural incomes in rich countries is greater than the fall in poor ones.But in Indonesia extremely dry forests are in flames.A multi－year drought(干旱) in south－east Brazil is becoming worse.Though heavy rains brought about by El Niño may relieve the drought in California，they are likely to cause surface flooding and other disasters.The most recent powerful Niño，in 1997－98，killed around 21，000 people and caused damage worth $36 billion around the globe.But such Niños come with months of warning，and so much is known about how they happen that governments can prepare.According to the Overseas Development Institute(ODI)，however，just 12% of disaster－relief funding in the past two decades has gone on reducing risks in advance，rather than recovery and rebuilding afterwards.This is despite evidence that a dollar spent on risk－reduction saves at least two on reconstruction.Simple improvements to infrastructure(基础设施) can reduce the spread of disease.Better sewers(下水道) make it less likely that heavy rain is followed by an outbreak of the disease of bad stomach.Stronger bridges mean villages are less likelyto be left without food and medicine after floods.According to a paper in 2011 by Mr Hsiang and co－authors，civil conflict is related to El Niño’s harmful effects—and the poorer the country，the stronger the link.Though the relationship may not be causal，helping divided communities to prepare for disasters would at least reduce the risk that those disasters are followed by killing and wounding people.Since the poorest are least likely to make up for their losses from disasters linked to El Niño，reducing their losses needs to be the priority.【语篇导读】本文是一篇说明文。
