Nature is turning on us
Task1:Summary main idea of each paragraph Task2:Complete the gaps in the text with sentences Task3: Practise and Expanding
? Main idea : ? Natural disasters are getting worse because of human activities.
Para 1: Para 2:
? Examples show natural disasters become common ? An example of volcanic eruption & earthquake show their threat to our world. ? Causes of natural disasters— Urbanization &industrialization ? Overpopulation in cities makes more people in the danger of natural disasters ? Experts predict that natural disasters will get worse
? Read the sentences before and after the gap and look for clues about the missing sentence.
? e.g. is it an example of what is mentioned before? ?
? Certain words may help you: time references (then). pronoun references (it, that), linking words (however).
? Decide which sentence goes in the gap. check that it fits the sentences before and after it.
Use the strategies to complete the gaps in the text(1-5) with these sentence(a-g),There are two extra sentences you do not need. ? A) But evidence shows that 73,000 years ago there was a much greater eruption. ? B) Even Europe has suffered and large areas have been underwater. ? C) This is probably not the most important factor either. ? D) Third, the other bits of land you might have been able to farm are now useless. ? E) On top of that add global warming. ? F) For example, the yellow river, once famous for flooding, failed to reach the sea at all for 226 days in 1997. ? G) One answer is overpopulation.

? These homes,seldom made of bricks,can easliy fall down in earthquakes or slip and slide downhill in landslides,especially in mountainous areas.(4)___This has mainly e been caused by the huge amounts of carbon dioxide produced by factories and vehicles,and the destruction of the world’s forests.
? The worst eruption in human history was probably Mt Tambora in 1815,in Indonesia.Dust from the volcano rolled across the earth’s skies and pretty much cancelled the following summer in Europe and America.(5)___ “It reduced a temperatures by maybe 6℃ in some places and the whole planet was sent into winter for years.
