From VOA Learning English, this is the Agriculture(农业的）Report.
Climate change has caused a rise in sea levels. This has increased the amount of salt in fresh water used on coastal farms. As a result farmers are increasingly unable to use fields close to the sea.
Scientists call this process "salinization（盐渍化）." The term（术语）comes from the word "saline" （生理盐水）-- which means a mixture of salt and water. The United Nations Food and Agriculture Organization says salinization is reducing the world's irrigated lands by 1 to 2 percent every year. Irrigation is the process of supplying land with fresh water from other areas.
As saline water cannot be used for irrigation, a farm in Netherlands has managed to grow healthy and tasty vegetables in soil irrigated with salt water.
But a farmer in the Netherlands is now using a mixture of sea and fresh water to grow healthy and tasty vegetables.
Marc Van Rijsselberghe started with an experiment. He put several kinds of plants in saline.
"We put in a lot of plants in the fields and then we put in, put them in fresh water and in sea water and all the varieties between it, and then we see which variety is surviving and which variety is dying."
Mr. Van Rijsselberghe worked on the project with scientists from the Free University of Amsterdam. He divided a farm into eight irrigated areas. Separate pipes pumped fresh and sea water, and a computer program created water with eight levels of salinity.
"And then computer says ‘go' and then it goes to the fields and dripping irrigation starts to work and we are going to kill plants. That's it."
Computerized measuring devices called "sensors" controlled the water levels and the levels of salinity. Mr. Van Rijsselberghe says he was able to harvest vegetables from most of the eight test areas. He says the vegetables were smaller than those grown in fresh water. But he says they also have more sugar and salt, so they taste better.
"It's a miracle. I mean, it shouldn't be a carrot, it should be dying if we look at the datas that are available in the world at the moment."
The farmer grew carrots, cabbage, onions and beetroot. But he found that potatoes grew better than the other vegetables in the combination of sea and fresh water. Mr. Van Rijsselberghe says four kinds of these potatoes were recently sent to Pakistan, where thousands of hectares of land have been damaged by salinization. Farmers in Pakistan will test the Dutch potatoes to see if they can be grown in those fields.

1．Three university students in Santiago,Chile have developed a phant-powerd device to charge their mobile phones.The three engineering students got the idea for the device while sitting in their school’s courtyard.Their invention is a small biological circuit they call E-Kaia.It captures the energy plants produce during photosynthesis.Aphant uses only a small part of the energy produced by that process,The rest goes into the soil.E-Kaia collects that energy.The device plugs into the ground and then into a mobile phone.The E-Kaia solved two problems for the engineering studnts,They needed an idea for a class project.They also needed an outlet to plug in their phones.One of the student inventors,CamilaRupcich,says the device charges the energy released from the plant into low-level power to charge phones.The E-Kaia is able to fully recharge a mobile phone in less than two hours.I’m Jonathan Evans. 2．University of Washington researchers say they used a laser to turn hot water into cool water. Five engineers from the university are the first in the 50-year history of the laser to refrigerate liquids under normal conditions with light beams. The group used a simple approach to the experiment. Lasers are known for producing hot temperatures. The University of Washington says they “essentially ran the laser phenomenon in reverse.” The discovery has a future in the computer and medical fields. Computer interiors could be cooled by lasers. In a medical laboratory, individual cells could be cooled to see how they react. “Few people have thought about how they could use this technology to solve problems because using lasers to refrigerate liquids hasn’t been possible before,” said researcher Peter Pauzauskie.The cool laser concept can also be used in manufacturing, telecommunications or national defense.The group has an interest in hearing from businesses or scientists who may have every day applications for the cool laser. The findings were published this month in the Proceedings of the National Academy of Sciences.

U.S. officials and many other Americans attended observances Friday to remember those killed and their loved ones. Nearly 3,000 people died on September 11, 2001 when hijackers used four passenger airplanes to carry out suicide attacks in the United States. In addition to the victims, the 19 hijackers also were killed. Al-Qaida leader Osama bin Laden and his group claimed responsibility for the attacks. U.S. forces killed him in a surprise raid on his hiding place in Pakistan four years ago. Friday morning, President Barack Obama, his wife and White House workers observed a public moment of silence in Washington. They gathered on the White House grounds at 8:46. That was the exact time when a hijacked airplane struck the World Trade Center. In New York, families of the victims gathered for a ringing of bells and reading of the names of those killed in the terrorist attacks. Moments of silence were held at 8:46 and 9:03 in the morning, when a second hijacked plane also hit the World Trade Center. Near Washington, U.S. Defense Secretary Ash Carter and other officials attended an observance at the Pentagon, the home of the Defense Department. They joined in remembering those killed when a hijacked airplane hit the Pentagon, killing 184 people. Earlier Friday, a large American flag was hung down the side of the Pentagon, where the passenger jet hit. There also was a moment of silence at 10:03 a.m. That was the time when a fourth hijacked plane crashed in western Pennsylvania. All 44 people on the plane were killed. Many Americans believe the hijackers had planned to attack a target in the nation’s

No.1 This is the VOA Special English Education Report. A program in the eastern United States invites young people into a prison to try to scare them away from prison. The goal is to teach them to avoid bad choices and bad influences that could put them behind bars for life. Students can take a tour of the prison, in school groups or by themselves. At the end, the young people sit down for a discussion with some of the inmates. The program is called Prisoners Against Teen Tragedy, or PATT. It takes place at the Maryland Correctional Institution-Hagerstown, a medium-security prison for men. Sal Mauriello is a case specialist there. SAL MAURIELLO: "We have a group of eleven inmates who are in the PATT program. They tell the youth what they went through as a child, what their crimes consist of. They try to teach them about peer pressure. They try to teach them about bad choices." The Prisoners Against Teen Tragedy program also includes an essay-writing contest. Tomi Dare is a seventeen-year-old student at Hagerstown Community College. She saw an announcement for the contest on her college website. To enter, students had to write about peer pressure and why they do not do drugs. The prize: five hundred dollars for school. In her essay, Ms. Dare wrote about her own experience growing up as an African-American girl interested in sports. T OMI DARE: "Drugs and alcohol not only slow a person down, it doesn't make you feel like you are a winner. It doesn't make you feel like you are the best. As an athlete, I'm 6-2 [188 centimeters], so I feel that I should be above peer pressure because I'm bigger than everybody that I’m around. "So I was talking about that and I was talking about how I consider myself a queen. And if I’m royalty, I need to not put substances in my body. Drugs and alcohol are not what a queen should be taking." The scholarship is presented by the Prisoners Against Teen Tragedy program. Prison spokesman Mark Vernarelli says most teens who visit come to understand what even one bad decision can mean. MARK VERNARELLI: "A lot of men and women serving life in prison in the state of Maryland didn't pull a trigger or plunge a knife into anybody. They were accessories to a crime. They

By VOA 22 July, 2015 From VOA Learning English, this is the Education Report. International students and workers must take a standardized test of English to move into higher levels of education and employment. There are three popular tests that universities or employers can use. They are the Test of English as a Foreign Language, TOEFL, the Test of English for International Communication, TOEIC, and the International English Language Testing System, IELTS. In most cases, the choice is clear. A student applying to a school learns which test the program requires. However, some programs or universities will accept scores from any of the international tests of English. Then, a student may choose which test to take. The TOEIC tests workplace communication The Educational Testing Service, ETS, in Princeton, New Jersey, develops and administers both the TOEFL and the TOEIC. It says the TOEIC measures the everyday English skills of people working in an international environment. A TOEFL preparation class The TOEIC test started in the 1970s. The Japanese Ministry of International Trade and Industry asked ETS to develop a test for corporations to use. They wanted to know if non-native English speakers could carry out business in English. The TOEIC is based on English used in the workplace. But the test does not require knowledge of special business words. The questions come from real situations like attending a company meeting. Organizations sometimes use the TOEIC to measure progress in English training programs. They also use it to consider people for placement at the right level in language programs. ETS says that 14,000 organizations in 150 countries use the TOEIC. The TOEFL tests English used in the classroom There are several versions of the TOEFL. Students take the Internet-based TOEFL, or TOEFL IBT, on a computer. Many U.S. universities require the TOEFL IBT for international student admissions. Another TOEFL is the paper-based TOEFL, or TOEFL ITP. It is part of ETS's institutional testing program. TOEFL ITP is used within institutions for the purpose of placement or to evaluate progress of students. It is not accepted for entrance to universities.

At the Smithsonian American Art Museum in Washington, D.C. you might see two cowboy boots. They are painted with a design of clouds and stars. They look like boots that you could wear on your feet. But they are really made out of carefully formed clay material. The artist William Wilhelmi made these ceramic pieces. How did he make these colorful boots? Today, we answer that question as we explore the world of clay art. (MUSIC) Smithsonian American Art Museum William Wilhelmi made "Cowboy Boots" in 1980. STEVE EMBER: Clay is one of the most universal materials known to humans. Throughout history and around the world, people have developed the art of forming clay to make ceramic objects, or pottery. Clay is m ade of water and earth. It is formed into different shapes. The n high levels of heat harden it to produce many kinds of ceramics. Different kinds of clay contain different minerals such as silicon or iron dioxide. The kinds of minerals in clay affect how soft or hard it is to work with. The mineral content of clay also affects the temperature level at which it hardens.

VOA《走遍美国》慢速英语2011-2-10 American History: Hoover Wins in 1928 The presidential election of nineteen twenty-eight gave American voters a clear political choice. The Democratic Party nominated Al Smith. He was the popular governor of the state of New York. The Republican Party chose Herbert Hoover. He was an engineer and businessman who served as secretary of commerce for presidents Warren Harding and Calvin Coolidge. This week in our series, Rich Kleinfeldt and Harry Monroe tell us about the presidential election of nineteen twenty-eight. RICH KLEINFELDT: Governor Alfred Smith of New York had campaigned for the Democratic presidential nomination in nineteen twenty-four. But he was defeated at the party convention by a compromise candidate, John Davis. Four years later, however, Smith could not be stopped. He had a strong record as governor of the nation's most heavily-populated state. He campaigned for the presidency on a policy of building new electric power stations under public control. Smith knew that many conservative Americans might be worried by his new ideas and his belief in strong government. So he chose as his campaign manager a Republican industrial leader who had worked with General Motors, DuPont and other major companies. Smith hoped this would prove his faith in the American private business system. HARRY MONROE: Al Smith was a strong political leader and an effective governor. But he frightened many Americans, especially conservative citizens living in rural areas. They lived on farms or in small towns. Al Smith was from the city. And not just from any city, but New York City, a place that seemed big and dirty and filled with foreign people and strange traditions. Al Smith's parents came from Ireland. He grew up in New York and worked as a salesman at the Fulton Fish Market. Smith was an honest man. But many rural Americans simply did not trust people from big cities. Al Smith seemed to them to represent everything that was new, different, and dangerous about American life. But being from New York City was not Al Smith's only problem. He also opposed the new national laws that made it illegal to buy or produce alcoholic drinks. And he had political ties to the New York political machine. But worst of all, in the eyes of many Americans, Al Smith was a Roman Catholic. RICH KLEINFELDT: From George Washington through Thomas Jefferson, Abraham Lincoln, and up to Calvin Coolidge, every American president had been male, white, and a Protestant Christian. Of
VOA慢速英语练听力需坚持
VOA慢速英语练听力需坚持 扫除词汇障碍 领会文章大意 这里需要提醒的是，在听的过程中，我们切忌将注意力全部集中在单词上，一个一个单词地去听，这样听的结果很可能是你把每个单词都听明白了，但是整篇文章到底讲了什么却是一头雾水。所以，在听的时候，我们应该以句子为单位，在大脑中将每个句子的关键信息迅速整合，这样才能了解每一句讲了什么、每一段又讲了什么，从而准确领会文章的大意。 反复精听训练 在进行系统的听力训练时，学习者仅仅理解了听力内容的大概是远远不够的，对于文章的诸多细节，比如一些重要的数据、年代和各种史实等，也要尽量准确无误地听出，这就需要通过反复精听来实现。所以科学系统的精听训练对学习者来说非常重要，通过精听训练，对于文章中的每一个语言点，甚至一些语音、语调、语汇的细微差别，学习者都可以努力捕捉和分辨。 因此，反复聆听，掌握每一个句子，是提升英语听力水平的必由之路！2遍、4遍、6遍……要有不听明白誓不罢休的精神。当然学习过程中还会出现这样的问题：单句可以听懂，但是段落、文章又听不懂了！怎么回事？原来反应太慢！这要求学习者根据自己的反应敏锐度来确定句子与句子的间距。 精听学习中需要提醒的是：在听的过程中，我们切忌对照英文原文来听或者是随意地翻看听力书的英文原文。很多同学都有这样的体会，在看英文原文之前，自己无论如何也听不懂，可是一看原文就什么都明白了，其实这样下来不是你“听”懂了，而是“看”懂了。 记住：阅读永远不可能代替听力，我们练习听力的目的就是要锻炼你对声音的瞬间反应、记忆、理解和思维的能力，而不是锻炼阅读能力。所
以这种取巧的方法万万要不得，你要想真正提高自己的听力水平，就一定要克制住自己翻看原文的欲望。 那么什么时候才是我们翻看听力原文的最佳时机呢？一般来说，我们只有在反复听了五遍、十遍还是听不出来的地方，才是英文原文发挥作用的良机。而这些你始终听不明白的地方，多数可能是因为音的连读、爆破、变音、弱读，或者是你反应不出来的词汇等等。在屡听而不懂的情况下翻看，你会在恍然大悟中将他们牢牢记住。并将他们仔细的琢磨，这样下次再遇上，你就会顺利过关。反之，这些难点将会成为你听力中永远的痛，在某个不经意的时刻将你重重阻碍。 VOA英语学习方法三步走 这次讨论的目的在于发现常见的错误的学习方法，总结出一套行之有效的最佳 VOA Special English 学习方法，欢迎大家积极参与讨论！ 最佳实践一：用 VOA Special English 练听力 网站上提供的 VOA Special English 节目文本是配有MP3声音的，声音文件由美国本土资深专业播音员录制，如果想有效提高自己的英语听力，VOA Special English 节目资料将是非常好的听力练习素材。而最快最有效的提高英语听力的方法就是做听写，怎么听呢？下面分几个层次介绍听写的方法。 （一）初级英语水平学生（相当于高中英语水平）做听写的方法 1、下载一个 5 分钟的 report 到电脑里（包括下载report的MP3录音和文本），准备好一本英汉词典或电子词典 2、认真阅读report文本一至两遍，遇到不懂的单词请立即查词典。 3、将文本放在一边，开始听report的MP3录音，并将听到的写下来，就是做听写练习。一直循环播放，尽可能的将自己能听写出来的，全部写出来。 4、将自己的听写稿和原稿对照，找出没有听写出来的词句，并标上记号，这些没有听出来的词句可能很简单，但事实是你没有听写出来，这些就是你听力的盲点，所以要特别留意。 5、再反复地听report的MP3录音，这次不用纸笔听写，而是在脑袋里做听写，就是指当你听到一句的时候，脑袋里把这一句给拼出来，确保听清每一个词句，并留意你在听写时没有写出来的词句的发音。 6、第二天再听上面的report的MP3录音，并采用上面第5点所用的听法。第四天再听上面的report的MP3录音，等到第七天再听几篇，仍采用上面第 5点所用的听法。为什么要反复地听？因为我们之所以听不懂，是因为听的太少了。反复听的目的在于强化，让你形成一种听力条件反射，就是让你拥有一听到某些词句就能立即条件反射式地在脑袋里写出来你所听到的词句。 练习听力有点像练习电脑打字里的盲打，花时间多做练习自然就会盲
