Coffee is probably world's least expensive success power tool to increase focus, drive and even the life span. 【小题1】 （fortunate）we may not be enjoying its benefits or pleasure too much longer. According to ecologists，there is a good chance 【小题2】 the varieties of coffee that we drink today 【小题3】 （be）extinct in 20 or 30 years. The problem, of course, is the pace of climate change.

Coffee is a crop that is only grown in a thin band 【小题4】（call）the “coffee belt” close to equator（赤道）, which is extremely vulnerable（易受...伤害的）to climate change. If the air is too hot 【小题5】 too cold, it prevents the growth of coffee plant. Climate change also creates 【小题6】 （environment）stress, which spreads pests and plant diseases.

As the major habitat of wild Asian elephants, Xishuangbanna has seen 【小题8】 significant growth in the population of elephants in recent decades, thanks to the joint efforts of the authorities and the residents. “【小题9】 (harmony) relationship between humans and elephants has been our goal, for【小题10】we will continue our efforts without hesitation,” said a local official in an interview.

The solution 【小题1】 the mystery of the monarch’s amazing ability comes at a time when it is in serious trouble. Its population 【小题2】 (crash) by as much as 90 per cent in the last few years. 【小题3】 (sad), human activity is the main reason 【小题4】 the number of monarch butterflies is falling.
