「2026 江苏南京高淳期末」
①One of the best parts of autumn is its beautiful colors. Normally green leaves turn into red, orange, yellow, and finally brown. This is called “leaf phenology”（叶片物候）, and many people look forward to it every year. However, because of climate change, autumn is changing.
②According to a study, the season length is growing, meaning that it is taking longer for leaves to change their colors. And this is not the only way that climate change is destroying the season.
③“Trees are holding onto their leaves longer,” explained Dr. Howard, a climate scientist. “In my own neighborhood, I can remember that the leaves would drop a lot sooner 20 years ago than they do now. This is a personal opinion, but research actually supports this phenomenon（现象） that we’re finding.”
④Climate change isn’t only causing the leaves to change later. We can also expect later frosts（霜） according to Dr. Michael, a teacher of a university. Michael said, “That means pests（害虫） will be active for a longer time in autumn, causing a greater health danger to human beings.”
⑤If there is no good news at all, though, we may be able to avoid this development. Michael said that if humans control their carbon dioxide emissions（二氧化碳排放）, they can still stop the worst effects of climate change. “A new study recently shows that warming will likely stop after carbon emissions reach zero,” Michael said in his recent comment for Live Science.
