The money has been spent on infrastructure like roads and stadiums for World Cup events. It also has paid for security and social projects. The government says these investments will result in long-term gains for Brazil, but independent experts say effects of the spending are mixed. Urban planners say the $11 billion spent on stadiums and infrastructure has created jobs for poor Brazilians, but they say this development has a price. The public works have driven up the cost of housing. This, say some experts, has push poor people further away from jobs and public services. Brazil stars mourn unhappy ending Some people are questioning the value of Police Pacification Units, called the UPP in Portuguese. Officials have sent the special police forces to drive out drug traffickers and other criminals. But the results have been mixed, says Chris Gaffney. He teaches at Fluminense University in Rio de Janeiro. Professor Gaffney says the drug traffickers just move their operations to other favelas. But he adds that the UPP have brought some order to once lawless neighborhoods. "These places were closed in many respects to the formal market. But the UPP goes in [to the favela] and it removes the barrier of the drug traffickers and allows all kinds of market forces to flow through it," explained Gaffney. He says these forces have opened some areas to tourism or state-support projects or businesses. The organizing body of the World Cup, FIFA, also invested in social programs. Lisa Delpy Neirotti is with Georgetown University in Washington D.C. She says the investments have led to programs for educating young people about the environment, the disease AIDS, or the importance of staying in school. She says FIFA pressure the Brazilian government to accept some pro-environmental measures like treating and reusing waster at stadiums. FIFA also wanted the structures built for the World Cup to meet the guidelines of LEED, or Leadership in Energy and Environmental Design. The U.S. Green Building Council set up the LEED Certification Program to recognize best in class building policies. Brazil's government says the World Cup will add billions of dollars to the economy, but many Brazilians believe the money will go to only a few people. Critics note some cities in Europe have rejected proposals to hold huge sporting events. They say a new models is needed if nations organizing such activities are to avoid protests like those earlier in Brazil. 全面掌握四六级考试信息，为备考复习做准备！ 什么人能考四六级：全日制专科、本科、研究生在校生可报考四六级，其中英语四级考试成绩达到425分以上（含425分）的在校大学生才可报考六级，同一考试批次，四级和六级不能兼报。点击查看更多>> 四六级什么时候考：大学英语四六级考试每年举办两次，分别是6月中下旬的周六和12月中下旬的周六，具体时间每年略有不同，需查看本校教务处报名通知了解。点击查看最新考试时间>> 四六级在哪儿报名：英语四六级考试现在都由各学校组织报名，一般会通过学校的教务网站或者各学院集体报名，报名后还有信息确认的过程，部分学校需要电子摄像。点击查看更多>> 四六级报名费要多少：四六级报名费用由各院校在报名时收取，不同地区及院校收费标准不同，一般在15-70元不等，部分院校不设立现场交费，采取从校园卡或银行卡统一划扣方式收取。点击查看更多>> 四六级考试流程是怎样的：英语四六级是同一天考试，上午考四级，下午考六级。考场上先试音，然后进行作文部分答题，之后是听力部分考试，最后是剩余题型考试。点击查看更多>> 四六级分数怎么计算：大学英语四、六级考试的分数报道采用常模参照方式，不设及格线。四六级考试单项成绩有四个部分，这四个部分以及所占的分值比例为：听力占35%，阅读占35%，翻译占15%，作文占15%。点击查看更多>> 四六级考试改革了哪些：CET考委会宣布从2013年12月考次起对英语四六级考试题型改革。本次四六级考试改革取消了完形填空、快速阅读，增加阅读理解匹配题，复合式听写改为单词和词组听写，句子翻译改为短文汉译英。点击了解更多>> 四六级成绩什么时候出：四六级考试成绩一般是考后两个月左右公布，一般在成绩查询开始前10天左右，四六级考委会网站会公布成绩查询通知，告知大家确切的成绩查询开始时间及成绩查询方式。点击了解更多>> 四六级多少分过：四六级报道成绩满分为710分，凡成绩在220分以上的考生，发给成绩单，不设官方及格线。但考委会规定“四级成绩达到425分以上（含425分）者方可报考六级”，故一般认为四级更多>>

He visited the western cities of Los Angeles and Seattle before travelling to Washington D.C. During the trip, the Commerce Minister spoke about the willingness of his government to make "deep" reforms to improve conditions for investment. He said the reforms would result in lower cost for investors. He said transportation and energy costs would be reduced. He also said the government would improve the skills of Cambodians through training. Mr Sun Chanthol said the new political will to make reforms is the result of the general elections last year. In the voting, the ruling Cambodian People's Party lost a number of seats in parliament. The opposition Cambodian National Rescue Party disputed the results. It said cheating was to blame. Cambodian Commerce Minister Sun Chanthol Alex Feldman is president of the U.S.-ASEAN Business Council. He says that among investors, interest in Cambodia has grown over time. But he says investors need to see more evidence of reform. "What the minister was talking about today was all very positive and all things that will attract business. We have seen progress. It's probably not been as much as the U.S. investors or the government would like. Hopefully, this time we make more progress. But we'll have to wait and see," said Feldman. Alex Feldman says Cambodia should continue to improve roads, ports and other infrastructure. He says the country also has to improve the skill base of its citizens and fight corruption. In 2013, Transparency International named Cambodia the most corrupt country in Southeast Asia. Sun Chanthol says the Cambodian government has taken major steps toward reform, these include passing an anti-corruption law and creating an agency to fight corruption. Storm Tiv works for the Asia division at Human Rights Watch. He admits that anti-corruption efforts have increased in Cambodia. But he says the lack of openness about the process will make them ineffective. "The lack of the ability to publicly disclose the assets of ministers keeps corruption as an issue. And so unless assets are publicly disclosed, corruption is still going to be an issue. The existence of an anti-corruption unit, then, doesn't seem to show any real difference in how Cambodia addresses corruption," said Tiv. Those who took part in the Washington meeting with the Commerce Minister said they were hopeful about Cambodia's reform plans. However, they said it was too soon to know if they would result in changes. 全面掌握四六级考试信息，为备考复习做准备！ 什么人能考四六级：全日制专科、本科、研究生在校生可报考四六级，其中英语四级考试成绩达到425分以上（含425分）的在校大学生才可报考六级，同一考试批次，四级和六级不能兼报。点击查看更多>> 四六级什么时候考：大学英语四六级考试每年举办两次，分别是6月中下旬的周六和12月中下旬的周六，具体时间每年略有不同，需查看本校教务处报名通知了解。点击查看最新考试时间>> 四六级在哪儿报名：英语四六级考试现在都由各学校组织报名，一般会通过学校的教务网站或者各学院集体报名，报名后还有信息确认的过程，部分学校需要电子摄像。点击查看更多>> 四六级报名费要多少：四六级报名费用由各院校在报名时收取，不同地区及院校收费标准不同，一般在15-70元不等，部分院校不设立现场交费，采取从校园卡或银行卡统一划扣方式收取。点击查看更多>> 四六级考试流程是怎样的：英语四六级是同一天考试，上午考四级，下午考六级。考场上先试音，然后进行作文部分答题，之后是听力部分考试，最后是剩余题型考试。点击查看更多>> 四六级分数怎么计算：大学英语四、六级考试的分数报道采用常模参照方式，不设及格线。四六级考试单项成绩有四个部分，这四个部分以及所占的分值比例为：听力占35%，阅读占35%，翻译占15%，作文占15%。点击查看更多>> 四六级考试改革了哪些：CET考委会宣布从2013年12月考次起对英语四六级考试题型改革。本次四六级考试改革取消了完形填空、快速阅读，增加阅读理解匹配题，复合式听写改为单词和词组听写，句子翻译改为短文汉译英。点击了解更多>> 四六级成绩什么时候出：四六级考试成绩一般是考后两个月左右公布，一般在成绩查询开始前10天左右，四六级考委会网站会公布成绩查询通知，告知大家确切的成绩查询开始时间及成绩查询方式。点击了解更多>> 四六级多少分过：四六级报道成绩满分为710分，凡成绩在220分以上的考生，发给成绩单，不设官方及格线。但考委会规定“四级成绩达到425分以上（含425分）者方可报考六级”，故一般认为四级更多>>

A robot is milking cows. It is milking time at Woodbourne Creamery in Mt. Airy, Maryland. The cows are standing in line for a turn at the robot. John Fendrick is the owner of the farm. He inspects the progress of the animals by looking at a computer screen. That is all he has to do. "The door of the milk opens up, they walk in, they get milked. The door opens up, they walk out." John Fendrick checks the progress on the screen. The robot does all the work. It uses a laser to find each teat -- the place on the cow where the milk comes out. The robot then cleans the teat and connects a milking tube to it. The robot also tests the milk for possible contamination. If it finds a problem, it rejects the milk. When the amount of milk coming out of the cow slows, the machine knows to stop, and sends the cow on its way. Milking robots are becoming popular among dairy farmers in the United States, Europe and Australia. John Fendrick says the robots have changed life on a dairy farm. "You are giving the freedom back. So it allows me or the people work for me to actually do other things on the farm." Most dairy farmers must milk their cows two times a day, early in the morning and late at night. The animals are milked everyday in good weather or bad. But Mr Fendrick's cows do not follow such schedule, they stay in the field until they want to be milked by the robot. Some of them come to be milked in the middle of the night. Mr Fendrick doesn't even need to be there to watch his cows be milked. He can watch from his telephone. He can learn when each cow was milked and how much she produced. He can also learn if a cow has not been milked for a long time. The cow milking robot is not low cost technology. Mr Fendrick paid more than $150,000 for it. But he notes, paying someone to milk the cows is also costly. "In three years, I will have paid off the difference with this, and I don't have to be the person who's always on call to milk. The fact that we have a life, and our cows are able to function without us -- to us, it's well worth the money." And he says that is a good thing. "I don't like to milk." With the robot, he can turn his attention to other things. He gets about 475 liters of milk a day, and he never has to touch a cow. 全面掌握四六级考试信息，为备考复习做准备！ 什么人能考四六级：全日制专科、本科、研究生在校生可报考四六级，其中英语四级考试成绩达到425分以上（含425分）的在校大学生才可报考六级，同一考试批次，四级和六级不能兼报。点击查看更多>> 四六级什么时候考：大学英语四六级考试每年举办两次，分别是6月中下旬的周六和12月中下旬的周六，具体时间每年略有不同，需查看本校教务处报名通知了解。点击查看最新考试时间>> 四六级在哪儿报名：英语四六级考试现在都由各学校组织报名，一般会通过学校的教务网站或者各学院集体报名，报名后还有信息确认的过程，部分学校需要电子摄像。点击查看更多>> 四六级报名费要多少：四六级报名费用由各院校在报名时收取，不同地区及院校收费标准不同，一般在15-70元不等，部分院校不设立现场交费，采取从校园卡或银行卡统一划扣方式收取。点击查看更多>> 四六级考试流程是怎样的：英语四六级是同一天考试，上午考四级，下午考六级。考场上先试音，然后进行作文部分答题，之后是听力部分考试，最后是剩余题型考试。点击查看更多>> 四六级分数怎么计算：大学英语四、六级考试的分数报道采用常模参照方式，不设及格线。四六级考试单项成绩有四个部分，这四个部分以及所占的分值比例为：听力占35%，阅读占35%，翻译占15%，作文占15%。点击查看更多>> 四六级考试改革了哪些：CET考委会宣布从2013年12月考次起对英语四六级考试题型改革。本次四六级考试改革取消了完形填空、快速阅读，增加阅读理解匹配题，复合式听写改为单词和词组听写，句子翻译改为短文汉译英。点击了解更多>> 四六级成绩什么时候出：四六级考试成绩一般是考后两个月左右公布，一般在成绩查询开始前10天左右，四六级考委会网站会公布成绩查询通知，告知大家确切的成绩查询开始时间及成绩查询方式。点击了解更多>> 四六级多少分过：四六级报道成绩满分为710分，凡成绩在220分以上的考生，发给成绩单，不设官方及格线。但考委会规定“四级成绩达到425分以上（含425分）者方可报考六级”，故一般认为四级更多>>

It can spread as much as 13,600 square kilometers, extending all the way to the eastern Texas coast. Scientists know what causes the dead zone -- too much nitrogen, but the solution might be hard to accept. Bayani Cardenas is a professor of water studies at the University of Texas at Austin. He says the movement of rivers usually removes material like nitrates. So he wondered why that natural filtration process does not remove nitrates from the Mississippi River. Dead pogies float in a fish kill in a pass near Bay Joe Wise on the Louisiana coast, Thursday, Sept. 16, 2010. Professor Cardenas says his recent study shows that more than 99 percent of the river's water does pass through the river's sediment which is on the shore or bottom of the river. But he says the study found that there is so much nitrogen in the river system that is simply can not filter all of it. The water that has nitrogen still in it supports the growth of algae. As the algae dies, it sinks to the bottom of the river where it breaks down or decomposes. It then takes oxygen from the water. This condition is called hypoxia and it is deadly to fish and shrimp. Where does all this nitrogen come from? The answer is farms. The Mississippi River system carries water from 33 American states and part of Canada to the gulf of Mexico. Along the way nitrogen and other chemicals used in farming enter the system. Farmers say these chemicals must be used to produce enough food for a growing world population. Aaron Packman is a professor of Civil and Environmental Engineering at Northwestern University. He says farmers may be able to better control the amount of nitrate fertilizer they put on fields. "How much fertilizer do you need to give you good yields and then how much is maybe a marginal gain from adding lots more fertilizer? There is really a question here: can you maybe [reduce the amount] and get close to the same level of yield without having such a negative impact?" said Packman. The water in the Mississippi River system should be able to clean itself naturally as it flows down stream. But flood controls and other human-made structures have hurt this filtering process. Storms in the next few month will mix the gulf water and the dead zone will disappear, but it will return next year. And scientists say it will grow larger in years to come, if something is not done to reduce the amount of nitrogen in the Mississippi River. 全面掌握四六级考试信息，为备考复习做准备！ 什么人能考四六级：全日制专科、本科、研究生在校生可报考四六级，其中英语四级考试成绩达到425分以上（含425分）的在校大学生才可报考六级，同一考试批次，四级和六级不能兼报。点击查看更多>> 四六级什么时候考：大学英语四六级考试每年举办两次，分别是6月中下旬的周六和12月中下旬的周六，具体时间每年略有不同，需查看本校教务处报名通知了解。点击查看最新考试时间>> 四六级在哪儿报名：英语四六级考试现在都由各学校组织报名，一般会通过学校的教务网站或者各学院集体报名，报名后还有信息确认的过程，部分学校需要电子摄像。点击查看更多>> 四六级报名费要多少：四六级报名费用由各院校在报名时收取，不同地区及院校收费标准不同，一般在15-70元不等，部分院校不设立现场交费，采取从校园卡或银行卡统一划扣方式收取。点击查看更多>> 四六级考试流程是怎样的：英语四六级是同一天考试，上午考四级，下午考六级。考场上先试音，然后进行作文部分答题，之后是听力部分考试，最后是剩余题型考试。点击查看更多>> 四六级分数怎么计算：大学英语四、六级考试的分数报道采用常模参照方式，不设及格线。四六级考试单项成绩有四个部分，这四个部分以及所占的分值比例为：听力占35%，阅读占35%，翻译占15%，作文占15%。点击查看更多>> 四六级考试改革了哪些：CET考委会宣布从2013年12月考次起对英语四六级考试题型改革。本次四六级考试改革取消了完形填空、快速阅读，增加阅读理解匹配题，复合式听写改为单词和词组听写，句子翻译改为短文汉译英。点击了解更多>> 四六级成绩什么时候出：四六级考试成绩一般是考后两个月左右公布，一般在成绩查询开始前10天左右，四六级考委会网站会公布成绩查询通知，告知大家确切的成绩查询开始时间及成绩查询方式。点击了解更多>> 四六级多少分过：四六级报道成绩满分为710分，凡成绩在220分以上的考生，发给成绩单，不设官方及格线。但考委会规定“四级成绩达到425分以上（含425分）者方可报考六级”，故一般认为四级更多>>

Three-D makes movies and video games look more realistic. And now it could help save lives. For years, mammograms have played an important role in finding breast cancer. But these X-ray pictures of the human breast often miss dangerous lumps or tumors. And they also produce false positives. A false positive wrongly appears to show suspicious tissue. And that causes painful, unnecessary biopsies to examine that tissue. A new study shows that three-D technology could change the way doctors look for breast cancer. A woman undergoes a mammography exam, a special type of X-ray of the breasts used to detect tumors. When Zulima Palacio discovered she had breast cancer, it already had reached stage three. That means that the cancer was very dangerous. "Even a month before it was detected, I went for a sonogram and they told me, 'You're fine, go home.'" Ms. Palacio is now cancer free. But the standard two-dimensional mammogram missed all three of her tumors. Many doctors - including cancer surgeon Negar Golesorkhi - say standard mammography does not find enough cancerous tumors. She says looking for cancer in dense, thick breast tissue is like looking for a polar bear in a snow storm. In other words, it is very difficult. "When we look for cancer on a mammogram in a dense breast tissue, we're looking for a polar bear in a snow storm, so it would be very difficult to find." A few years ago, the U.S. Food and Drug Administration approved the use of three-D mammography. And three-D technology found Jennifer Hoeft's tumor. "It was a very small tumor. It was only an 8 millimeter tumor that couldn't be felt." Sarah Friedewald is a doctor at Lutheran General Hospital in the U.S. state of Illinois. She led a study to compare the results of three-D and two-D mammography from nearly a half million patients. Dr. Friedewald says they found more cancers using three-D mammograms versus, or compared to, two-D mammograms. And they found more cancers that kill. "We found invasive cancers or the cancers that we worry about, the ones that could potentially kill people more frequently in women who had the 3-D mammogram versus the women who just had the 2-D mammogram."

美好。(但事实上没有。) 　　When things don’t turn out as we would like them to, it is very tempting to assume that had we done things differently, the story would have had a happier ending. 方框部分作为assume后的宾语从句，根据had done，would have had 时态得知，此处实则为虚拟情况，与过去情况虚拟。此处的虚拟还用到了倒装的语法，省略if，将had提前，变成正常语序即为if we had done things differently, the story would have had a happier ending。 因为虚拟，所以事实上，我们并没有用不同的方式来英语四级考试是大学生必须要通过的，但是很多人的英语能力非常的不好，尤其是听力差的考生，那么在面对四级处理，结局还是一样不美好。 　　如此，便能读懂作者，听懂说话人真正想要表达的含义。如果你现在还在纠结到底要用何种技巧解题，何不提升语法基础，做到听懂看懂考题，那一切的技巧都将四级考试是大学生必须要通过的，但是很多人的英语能力非常的不好，尤其是听力差的考生，那么在面对四级考试的时候，大家应该如何提高的，找到原因很关键，今天我们就为大家整理了英语四级听力差的五大原因，一起来了解一下吧。 　　一、何谓虚拟? 　　在英语中，语气(mood)和时态，语态一样，都是谓语动词的一种形式。表明说话的目的和意图，虚拟语气即表示说话人主观愿望或纯假设情况，动词需用特殊形式。例如If I were a boy。其中谓语动词用were，而不是am, shall, was, have等，是因为说话人为女士，而“我是男人”仅是其假设的语气，故用了一个在现实情况中绝不可能用到的were来表达这一虚拟的情况。通过在I的后面加were这一词，能得知这是虚拟假设出来的情况。 　　常见的虚拟有两种： 　　1. 表示非真实假设情况： 　　If If I had left sooner, I could have caught the train。 　　如果早点出发，我就能赶上火车了。(但我事实上已经错过了，对过去的假设虚拟) 　　He talks so loud as if I were deaf。 　　他说话声太响，就像我聋了一样。 (但事实我没聋，对现在的假设虚拟) 　　这种情况虚拟时，只需将谓语动词变本身的时态再变过去。第一句话中的虚拟，本身为过去时，因此再变过去，即过去完成时。left变为had left, could catch变为could have caught。第二句话中，as if I am deaf，需要对现在假设，因此变为as if I were a deaf。(不用I was deaf，避免与真实情况过去式混淆)类似表示非真实情况的词还有wish希望， suppose假设， would rather宁愿， but for要不是等。 　　2. 表示建议、命令、要求等主观意愿： 　　He suggested that a petition (should) be drawn up。 　　这种虚拟时，不管句子时态如何，表示建议、命令、要求部分的谓语都统一用should do，should可以省略。类似表示建议、命令、要求的常见句型还有sb. suggest /advise /ask /demand /propose /...+ that 从句，或It is important/necessary/essential/ crucial/suggested/advised... +that从句，从句部分表虚拟，其中谓语用(should) do。 　　二、四级考试中的虚拟语气 　　例一：2011.12月四级听力短对话第12题 　　12.A) He was looking forward to seeing the giraffes。 　　B) He enjoyed watching the animal performance。 　　C) He got home too late to see the TV special。 　　D) He fell asleep in the middle of the TV program。 　　W: I really enjoyed the TV special about giraffes last night. Did you get home in time to see it? 　　M: Oh, yes, but I wish I could have stayed awake long enough to see the whole thing。 　　Q: What does the man mean? 　　在这一对话中，女士问是否及时回家看了这个节目?回答时，男士用了I wish一词，也就是表示他后面说的话为假设虚拟部分，与真实情况相反，因此他说的stayed awake long enough to see the whole thing是假设，真实情况为他中途睡着，并未看完整期节目。因此在选择选项时，因选择D。 　　例二：2011年12月四级阅读 　　For example, but for the savings and loan debacle, there might be funds available to reduce the national debt and pay for education。 　　参考译文：举例来说，要不是储蓄和储贷危机，也许还有资金来偿还国家债务和向教育拨款。(而事实上没有资金) 　　这句话中，but for，表示“要不是”，表示虚拟，所以句子后面的内容为假设情况，与事实相反，因此funds 并不是available的，其真实想表达的含义是没有资金。 　　例三：2001年1月四级成为浮云。
