[Q]: Article: While the rest of his family was happily feasting during Spring Festival, Zu Xinming, a Senior 2 student in Shaanxi province, was frowning. "Every time my  s leave after dinner, almost half of the dishes are unfinished," he said, and we throw away a lot of food. Nowadays in China, food waste is a widespread problem. Each year, Chinese people throw away the equivalent   of about 50 million tons of grain, an amount which could feed 200 million people, according to Xinhua News Agency.    One reason is that people are unaware of the issue.    "Some of my friends don't care at all when they can't finish the food on their plates," said Zu, "and they even throw it away if they don't like the taste."    Gong Tao, an official from the Communist Youth League of China Committee of Central South University in Hunan province, is worried about the decreasing awareness of food waste on his campus in recent years.    "Students don't know how much hard work others go through in order to provide their food," Gao told China Education Daily.    One deeper factor is the Chinese cultural value of "face". In a Chinese banquet   setting, the host feels great shame when guests' plates are empty. "Serving lots of food is the Chinese way of showing respect to guests and displaying generosity," Yu Changjiang, a sociologist at Peking University, told Xinhua.     Huge public spending on government banquets is also worsening the situation. Government banquets at the taxpayer's expense   have become "a major source of waste", commented People's Daily.    The good news is that people are already beginning to take action. On Jan 16, 10 restaurants with 749 outlets   in Beijing joined an "eating up" campaign promoted by Xu Xiake, deputy director of China Land and Resources News. These restaurants have begun serving half-sized meals and small dishes.    So, how can you help reduce food waste? Discuss with your family regularly about your food preferences and how much you want to eat. Eat all of the food on your plate and in your bowl. And each week, help your parents clean the fridge so that all of the food gets eaten before it goes to waste. 
 Answer: In Chinese culture, people show their welcome by serving lots of food.
[A]: According to the passage, which of the following is true?


[Q]: Article: As you climb into the hill country, the roads get dustier and rougher, and fewer cars can be seen. Phonxay is one of the poorest districts of Laos, and many of its villages are only accessible by footpath. Our destination this hot morning is a concrete water tank that can be found just off the road. A UK organization helped to build it six years ago, and in the nearby village of Thapho, where clean drinking water is scarce, it has made a big difference. The tank feeds six taps which in turn give water to over 800 people---it has improved things for almost every family, from schoolchildren to grannies. But lately, we were told, the clean water supply has come under pressure from new arrivals, people who have come down from the hill areas, and there are concerns that there will not be enough clean water to go round. There are also serious worries about resources in Laos. The Chinese are building a 400km railway link, which could transform the landlocked country. About 150,000 Chinese workers will be involved. What will this do to local clean water supplies? How will the workers be fed? The vast majority of Laotians live on farms. But with foreign investors wanting to buy up land, local people will have to be moved to make room for them. Heavily dependent on both foreign aid and foreign investment, Laos still falls well behind its neighbours, although its economy has grown at about 6% a year in the last decade. Its biggest economic problem is the lack of locally trained skilled workforce. But there are reasons to be hopeful for the future. Laos is beautiful, and foreign tourism continues to grow: fortunately so far the fast-food chains and coffee bars common elsewhere are nowhere to be seen. Although all local media are government-run, the Internet is not controlled and the BBC and CNN are available to those with satellite dishes. The government has also achieved impressive results in rural development, with communities benefiting not just from cleaner water but the construction of new schools and regular visits from medical teams. Poverty will not be history in Laos within the next decade, but with small steps forward and a bit of outside help, the country could find itself out of the UN's least-developed category by 2020. 
 Answer: The coming summer will dry up rivers and lakes.
