Article: As people in Beijing and northern China struggle with severe air pollution this winter,the toxic air is also making life hard for plants and even food crops of China. "in the last 50 years there has been a 1 6-fold increase in ozone pollution"in the Beijing area,said Hanqin Tian of Auburn University in Alabama,who studies the effects of China's pollution and climate change on plants. Ozone is particularly harmful to plants because it damages the pores on leaves,called stomata,which plants use to regulate how much water evaporates from the leaves.That,in turn,affectS how much water a plant must take up through its roots.Changes in water uptake by plants have been documented in other parts of the world,including the United States,as having major impacts on regional groundwater and surface water supplies. In studies of the long-term productivity of plants,Hanqin Tian and some of his colleagues show that ozone pollution,along with climate change,has been lowering plant productivity in China,which reduces the amount of carbon and other pollutants that the plants Can absorb to fight all the emissions from the burning offossil fuels. The worst effects on plants are likely to be in areas where the growing pollution problem is just fairly new, said Arthur Chappelka, also a plant researcher at Auburn University.Some plants are more resistant to pollutants than others,he said,and the plants that are living today in long-polluted urban areas are likely to be only those that are very pollution tolerant. Away from the cities, however, where crops are necded to feed China's yast population, the effeets of the growing pollution on crops is a significant concern. "In some ways it affects the crop production and food securiy of China,"said Hanqin Tian."Air quality is really important for human health, plants and ecosystem and sustainability." The problem is bound to get worse as China continues to develop economically, he said, and so he and other researchers continue to urge the Chinese government to take action to reduce...

Question: Read the following article and select the best answer. Article: My son wanted to give a party for my birthday. We discussed the invitations and the cost of the party. However, we had very different ideas about whom and how many people to invite. He thought that the people we knew had badly disappointed me by not keeping in touch with me since the death of my wife. But my idea of a relationship among people was to be friendly to everyone. He said, "Come on, Dad, where have all these so-called friendly, good people been since Mum passed away? They visited us in the past because Mum made good food." I replied, "I am sorry to hear that. Is this the reason why you do not want to invite those people? It's no wonder that you are unhappy. Can you live alone? Are you teaching your children to do the same in the future?" I asked myself where I had gone in his upbringing. My wife had often blamed me for not paying enough attention to communication with other people when I was raising our son. I realized at this moment that she was quite right. Hours later, my son phoned me to say that he accepted his wife's advice and agreed to have a party with some of my friends. In the end, we had a great time. And he didn't "hate" those friends any more. "Happy Birthday, Dad! Sorry that I have kept you away from your friends. I love you." On hearing what he said, I was full of happiness and excitement. I was proud that he could change his mind.
