Green Hills, Clear Water, Blue Sky is a project that was set up by the government three years ago. Since it was started, many people【小题1】 (take) part. They think it is 【小题2】 (they) duty to make the Earth【小题3】 (beauty) and peaceful. At【小题4】 same time, they insist that the government should play an important role and try their best【小题5】 (protect) the environment. Some answers of factories are damaging the environment by 【小题6】 (pollute) rivers with chemical waste. So it is 【小题7】 (believe) that the government should pass laws to punish people【小题8】 damage the environment. Besides, the government should build conservation centres so that plants and animals 【小题9】 danger can be protected.

All in all, people and the government should work side by side to take care【小题10】 the Earth.

In the last few years,environmental disasters 【小题1】(become) more and more common.Terrible floods and storms are getting worse and worse everywhere and 【小题2】(reduce) rainfall brings about more severe droughts.Volcanic【小题3】 (eruption) and earthquakes are often the case.Overpopulation is the main reason.【小题4】 top of that,global warming and the 【小题5】(destroy) of the world’s forests contribute a lot to it.Of course,landslides and earthquakes have an important role 【小题6】(play) in it.Homes built from 【小题7】 materials that could be found can easily collapse during earthquakes or landslides,【小题8】 (especial) after heavy rain.Most disaster experts believe,if we don’t take immediate action,things could get 【小题9】 lot worse.For example,we haven’t seen the 【小题10】(bad) result of eruption.

Human activity is 【小题1】 (fundamental) altering the distances the world’s animals need to move to live, hunt and search for food, according to a study that examined the impact 【小题2】 more than 160 species throughout six continents.

All activities changed the behavior of animals , but the study found 【小题3】(destroy) activities such as urbanization and cutting down trees affected the movement of animals less than occasional endeavors (努力) such as using aircraft, hunting and recreation.

As well as having a profound influence on the animals — like reducing their ability to feed and breed — the changes point to a global restructuring of animal movement 【小题4】 could have profound knock — on effects, says the study published today in the Nature Ecology and Evolution journal.

Dr Tim Doherty, a wildlife ecologist at the University of Sydney, said it was already well known that humans 【小题5】 (affect) the movement of animals, with thousands of studies 【小题6】(tend) to focus on single species or activities, but the information was not enough.

When human 【小题7】(active) forced animals to move further, such as when animals fled hunters or had to negotiate roads or avoid skiers or campers, they moved an average of 70 percent further in 【小题8】(respond). The research says, “Even 【小题9】 small change in movement can have big effects on an individual, and when these costs accumulate across an entire population, reproductive rates and population viability may 【小题10】(compromise).”
