Lindsay Renwick, the mayor of Deniliquin, a country town in New South Wales, misses the constant whir(嗡嗡声)of the rice mill whose giant fans dried the rice. The Deniliquin mill, the largest rice mill in the Southern Hemisphere (南半球), once processed enough grain to meet the needs of 20 million people globally. But six years of drought have had a destructive effect, reducing Australia's rice crop by 98 percent and leading to the mothballing of the mill last December.
Drought affects every agriculture industry based in Australia, not just rice – from sheep farming, the country's other backbone, to the cultivation of grapes for wine, the fastest-growing crop there, with that expansion often coming at the expense of rice. The drought's effect on rice has produced the greatest impact on the rest of the world, so far. It is one factor contributing to skyrocketing prices, and many scientists believe it is among the earliest signs that a warming planet is starting to affect food production.
Researchers are looking for solutions to global rice shortages – for example, rice that blooms earlier in the day, when it is cooler, to fight against global warming. Rice plants that happen to bloom on hot days are less likely to produce grains of rice, a difficulty that is already starting to emerge in inland areas of China and other Asian countries as temperatures begin to climb. 'there will be problems very soon unless we have new varieties of rice in place,” said Reiner Wassmann, climate change director at the International Rice Research Institute (IRRI). The recent reports on climate change carried a warning that could make the news even worse: that existing models for the effects of climate change on agriculture did not yet include newer findings that global warming could reduce rainfall and make it more variable.
Yet the effects of climate change are not uniformly bad for rice. Rising concentrations (浓度) of carbon dioxide, the main greenhouse gas, can actually help rice – although the effect reduces or disappears if the plants face unnecessary heat, inadequate water, severe pollution or other stresses. Still, the flexibility of farmers here has persuaded some climate experts that, particularly in developed countries, the effects of climate change may be relieved, if not completely avoided. “I'm not as negative as most people,” said Will Steffen, director of the Fenner School of Environment and Society at Australian National University. “Farmers are learning how to do things differently.”
Meanwhile, changes like the use of water to grow wine grapes instead of rice carry their own costs, as the developing world is discovering. “Rice is an essential food,” said Graeme Haley, the general manager of the town of Deniliquin. “Wine is not.”

Ready for final year
Even though they're anxiously awaiting their gaokao, Senior 3 students feel relieved after having survived their busiest year of high school.
Your milestone year begins in just two months, so how can you make the most of it? Here, three graduates offer some practical advice to help you navigate (航行) your final year in the right way.
Sun Hairuo, High School Affiliated to Renmin University of China, Beijing:
Think ahead about your major. Even though some universities allow students to switch to a new major after enrollment, it still involves a lot of effort to do. So while you're preparing for the gaokao, start to consider what field you want to major in at the same time.
When I was aware of my interest in social science, I began to collect information on the internet about what courses I'd like to take in university and what life would be like on campus if I chose this direction. Don't judge a major before you know everything about it, since your entire future depends on it.
Qian Wenjing, Hangzhou Foreign Language School, Zhejiang:
Enjoy a hobby alongside your studies. It's important to get high marks in all subjects, but if you have nothing that can distract you from the piles of homework, you'll have no motivation.
For example, I run a WeChat public account, which you can find by searching for “大嘴小个儿” on WeChat. On it, I share my reflections on life, recommend good books and introduce learning methods to others. I also make videos on how to write an interesting daily journal for the video platform bilibili.com.
So, keep on top of your schoolwork, but make sure you find time to let your hair down sometimes too.
Wang Zixin, Beijing No 4 High School, Beijing:
Create your own system of knowledge using a notebook. In the review stage, find your weak points on every science subject after each exam. Summarize the knowledge behind the errors in your notebook — this will not only identify the problem, but will also save you time when you don't have to spend so long figuring out the answer.
As for liberal arts subjects such as Chinese and English, write down any memorable sentences you come across in your notebook.
And keep it in mind that improvements don't happen right away — it takes time to get better.
