高一英语第一学期完形填空训练高一英语第一学期完形填空训练 六六To know just what the effect of global warming will be in the future is extremely difficult, if not impossible. Scientists 1 computer models to study the 2 of global warming. These computer models have been fairly consistent (一致的) in 3 general future trends, 4 often differ greatly when looking at the specifics.5 scientists say global warming has already been going on for a while. Others say that we do not have enough 6 now to know for sure.7 the disagreements, most scientists are convinced that greenhouse gases are warming the Earth. 8 they are still trying to figure out is how quickly 9 are rising, and what will happen 10 a result.The climate changes that will 11 global warming are extremely 12 to predict. The weather is 13 by so many factors that it is often compared to chaos by scientists. Changing the temperature will likely have some effect on the planets 14 , but just what that effect will be is nearly impossible to 15 .If temperatures do indeed rise significantly, the most important result would be that some portion of the polar ice caps (冰盖) would 16 , raising global sea levels.The rise in sea levels would be for disastrous some places. Islands would 17 , meaning their millions of inhabitants would have to relocate (迁移). 18 would occur along coastlines all over the world, displacing more people and 19 cropland (耕地).In the case of major global warming and melted ice caps, some countries might simply cease to exist.
