One evening in February 2007 . a student named Paula Ceely brought her car to a stop on a remote in Wales . She got out to open a metal gate that blocked her path . That's when she heard the whistle sounded by the driver of a train.Her Renault Clio parked across a railway line. Second later,she watched the train drag her car almost a kilometre down the railway tracks. Ceely's _ made the news because she blamed it on her GPS device .She had never driven the route before .It was dark and raining heavily . Ceely was relying on her GPS. But it made no mention of the crossing ."I put my complete trust in the device and it led me right into the path of a speeding train ,"she told the BBC. W ho is to blame here ? Rick Stevenson ,who tells Ceely's story in his book When Machines Fail US, finger at the limitations of technology. We put our faith in digital devices, he says, but our digital helpers are too often not up to the job. They are filled with small problems. And it's not just GPS devices: Stevenson takes us on a tour of digital disasters involving everything from mobile phones to wireless key boards. The problem with his argument in the book is that it's not clear why he only focuses digital technology,while there may be a number of other possible causes. A map-maker might have left the crossing off a paper map. Maybe we should blame Ceely for not paying attention. perhaps the railway authorities are at fault for poor signaling system. Or maybe someone has studied the relative dangers and worked out that there really is something specific wrong with the CPS equipment. But Stevenson doesn't say. It's a problem that runs through the book. In a section on cars, Stevenson gives an accout of the advanced techniques that criminals use to defeat computer-based locking systems for cars. He offers two independent sets of figures on car theft; both show a small rise in some parts of the country. He says that once once again not all new locks have proved reliable. Perhaps, but maybe it's also due to the shortage of... Which of the following would Rick Stevenson most probably agree with? A) Moderntechnologyiswhatwe can'tlivewithout. B) Digitaltechnologyoftenfalls shortofoutexpectation. C) Digitaldevicesaremore reliablethantheyusedtobe. D) GPSerrorisnottheonly causeforCelery'saccident.

Studying abroad will shape you in various ways. You will learn things you never would have if you study overseas. But college is expensive in the United States. It's cheap or free in other countries even for foreigners, so why not get out of here and come back smarter? More and more American students are currently studying at German colleges. That number has increased by 20% over the last three years. Living costs are about $7,000 a year, which is even lower than in other European countries and a great appeal to many students wanting to studying abroad. Besides, Germany encourages international students. They create a multicultural landscape that benefits German students as well. According to a new report, Germany is home to six of the world's 100 best universities. These schools offer around 900 degrees completely in English and many German students speak the language. You could be part of Finland's excellent education system. The Finns charge no tuition and offer a number of courses purely in English. They would be happy for you to add flavor to their school scene. Cost of living there is high. Be prepared for frosty winters, but you will get that sweet midnight sun in the summer. Many other European nations provide cheap or free college for foreign students, but if South America is more your thing, try Brazil. Most of the education will take place in Portuguese, so if that is in your plan you can study near beautiful beaches and jungles. The University of Sao Paulo and State University of Campinas are both highly ranked internationally. Your money will go a long way there, too. Living on the economy in a foreign country will keep you on your toes. You will learn new customs, how to bargain, stay safe, budget and become more flexible with people. There is no better way to learn a language than by immersing yourself in it. What's more, you will become a more balanced person. New situations and challenges, from buying bread to traveling across town, will pop up daily. You will handle them and you'll make it... What is the author's attitude towards studying abroad? A) Approving. B) Doubtful. C) Critical. D) Neutral.

*Question*
Have you heard of snake robots? Scientists and doctors are already using tiny snakes that coil through the human body armed with sharp surgical tools to perform operations on hearts, prostate cancer, and other diseased organs. The snake robots that carry tiny cameras, scissors and forceps, and even more advanced sensors are being developed. The next generation of the robots will be wireless, and will explore inside your body on their own--- not attached to any cables. For now, they are powered by cables that humans control. Experts say the day is coming when some robots will roam around the body on their own. But the experts in robotics say the new creations work best when they are designed for very specific tasks. Howie Choset has been researching and building robots, particularly snake robots. He believes that his snake robot and others like it can help reduce medical costs by making complex surgery faster and easier. Choset says his new design is smaller and more flexible than earlier models. The size of surgical robots allows surgeons to operate with far less damage to the body, helping the patient heal faster. Choset has also built larger snake robots designed for search and rescue, or just exploration. They can climb poles and trees and then look around through a camera in the head and slither through places that humans cannot reach. " We sent our snake robots into these caves in the Red Sea to look for evidence of ancient Egyptian ships," he said. " To me, archeology is like search and rescue, but everyone has been dead for 5,000 years." The doctors are very excited about the potential for surgical robots to do things that humans can't do. The variety of sensors available for surgical robots keeps expanding. As they get smaller, maybe one day they will be able to test chemicals or blood in the body, or even the electrical connections in nerves. The writers attitude towards the new technology is _ . A) optimistic B) doubtful C) objective D) negative
