安阳市第三十六中学2017—2018学年高一年级第二学期期末考试英语试卷 （满分150分 ，时间120分钟） 第I卷 第一部分 听力（略） 第二部分 阅读理解（共两节，满分40分） 第一节（共15小题；每小题2分，满分30分） 阅读下列短文，从每题所给的四个选项 （A 、B 、C 和 D ）中 ，选出最佳选项，并在答题卡上将该项涂黑。 A Vinegar（醋）is great. It makes salad, fries and dumplings taste better, and you can even clean your windows with it. And now, according to scientists，it may even help the planet’s population survive climate change. Researchers from the RIKEN Center for Sustainable Resource Science (CSRS) in Japan proved that. They found growing plants in vinegar makes them more resistant to droughts. This could mean that in the future，worries about climate change affecting the world’s supply of food will be much lower. The discovery was made after the researchers studied the Arabidopsis, a plant known for its ability to survive in dry weather. It was found that when the plant was placed in drought-like conditions, it produced a chemical called acetate（醋酸盐）-- the main component of vinegar. After discovering this, the scientists experimented further by adding acetate to the soil of other plants before they stopped giving them water completely. After leaving the plants for 14 days, they found that the ones treated with acetate had survived, while the untreated plants had dried up and died. It’s hoped that this simple method of survival could soon be used to help farmers in dry countries keep their crops alive. “In the experiment, we targeted the basic foods of the world—rice, wheat and maize... and proved successful” Jong Myong Kim, co-author of the study, told Popular Science magazine. Kim has already been in touch with people around the world who are interested in trying this simple and cost-effective method out for themselves from farmers to companies and amateur gardeners. “Now we are trying to cooperate with them to make a method to apply this system, and make the process as simple as possible,” he said. Hopefully this means the end of hunger caused by bad weather in the future. 21. What does the underlined word “that” in paragraph 1 refer to? A. Vinegar may help creatures survive bad weather. B.
