In 2013, a lot of people ②were shocked (shock) by a news photo of a dead polar bear on Norway’s Arctic island of Svalbard. Due to the increase in temperature, the polar bear seemed ③to have died (die) from lack of food.  According to climate scientists, a key climate process, ④which is called the “greenhouse effect”,includes the “natural” greenhouse effect and the “man⁃made” greenhouse effect. The former refers to the fact that heat from the sun ⑤enters (enter) the atmosphere and warms Earth’s surface. Greenhouse gases in the atmosphere trap some of the heat, ⑥keeping (keep) Earth’s climate warm and habitable. However, the latter has become ⑦a big problem. When people burn fossil fuels, more heat energy is trapped in the atmosphere and causes Earth’s surface temperature to rise ⑧quickly (quick). The evidence shows that the rise in temperature has led to an increase in extreme weather and natural ⑨disasters (disaster) worldwide. Climate scientists warn that this warming trend will become ⑩worse (bad) if we do not take appropriate measures. The severe situation requires people all over the world to pay more attention to it, because this is the most serious issue affecting all of us on this planet. 学科网（北京）股份有限公司 $
