例如：
Michael Faraday was born near London, the son of a blacksmith. His first job was in a bookshop, but in 1813 he started work as a laboratory assistant at the Royal Institution in London. In 1844 he was made professor of chemistry there. Many people now ① view Faraday as the greatest of all experimental physicists. He was one of the first people to try to make science popular with the general public. In 1826 he gave the first lectures about science for children, at the Royal Institution. These are still ② held every year.
1. (A) think (B) refer (C) view (D) deem

Scientists have been devoted to figuring out the possibility of solving the problem of global warming since it’s getting worse and worse. Research by Amstrup’s team has shown that if current trends persist, at least two-thirds of the world’s polar bears are likely to vanish by 2100. However, Amstrup subverted his previous speculation and concluded that there is still hope for polar bears if greenhouse-gas emissions are significantly reduced and atmospheric concentrations of heat-trapping pollutants are stabilized within the next decade.
Another climate expert Joseph Romm, a Senior Fellow at the Center for American Progress, indicated that the industrialized world has to cut 60% to 70% almost immediately and continue cutting forever. He also concluded that the overriding problem is in fact a lack of political will — the world is not willing to do so. The rapid rate at which we emit the heat-trapping pollutants is actually unprecedented. It is estimated that if our emissions continue on the current trajectory, the problem will be even severer than 35 million years ago, when the arctic temperatures were 20 degrees higher than they currently are. In that case, the devastating impact would endanger not only polar bears but also human beings. The extreme weather would extirpate a tremendous number of species, many of which humans depend on for food.
In spite of an abundance of studies, whether human beings can make it to reverse the climate change is still unknown. What we can do is try our best to stop the situation from worsening.
