Q: I'm taking a test and have to guess the right answer to the question after the article. Article: When a dog loses a leg, the animal eventually figures out the best way to get around on three legs. In a short time, the dog learns to deal with its physical disability. Now, scientists have developed robots that behave in much the same way. We can find robots everywhere. Robots build cars, play chess and can clean your house. They may someday drive your car, too. Two robots, named Spirit and Opportunity, were sent to Mars on a mission to explore the red planet. Jeff Clune is a computer scientist with the University of Wyoming. He says robots also help people in natural disasters. Robots are deployed in search and rescue operations following an earthquake. They may someday also be used to examine the wreckage of a nuclear accident, like the one in Fukushima, Japan. Mr. Clune says robots can be sent to a lot of places said to be unsafe. "The problem is that all of those types of situations and environment are extremely unpredictable and dangerous. And it is very likely that robots and humans in those situations become damaged." He and other scientists are developing technology so that robots will continue operating after the first sign of injury. They want the machines to have the ability to make changes and continue performing until they can be repaired. Mr. Clune and researchers in France have added one more operation to the skill set of robots working under difficult conditions. They say they programmed a hexapod robot, one with six legs, and a robotic arm to learn how to deal with injury. Their findings were reported in the journal "Nature". Mr. Clune said that once the robots become damaged, they use their intuition and knowledge of how their body works to find a way to deal with the damage. He says the robots are also programmed with child-like curiosity. In other words, they are always asking questions and looking for answers. The whole process takes about a minute for the robots to find a way to overcome damage. Question: Now scientists have developed robots that, once damaged, can   _  . Options: A: rely on their functions to figure out a way to handle the emergency. B: figure out the best way to get around in a short time C: spend about a second finding a way to overcome damage D: maintain their child-like curiosity and keep asking people around for solutions
A: A


Q: I'm taking a test and have to guess the right answer to the question after the article. Article: TUVALU, a tiny country in the Pacific Ocean, has asked for help as it will be swallowed up by the sea.        Storms and huge waves are a constant threat and none of Tuvalu's nine little islands is more than five meters above sea level.Salt water is already entering the country's drinking water supply, as well as damaging plants that produce fruit and vegetables.Without urgent help, the country's days are numbered.        But Tuvalu is not the first place to face sinking into the sea.Venice, a historic city in Italy best known for its canals, has sunk about 24cm over the past 100 years.Experts say that it will have sunk another 20-50cm by 2050.A century ago, St.Mark's Square, the lowest point city, flooded about nine times a year.Nowadays, it happens more than 100 times.While Venice is slowly sinking into the mud on which it stands, global warming causes Tuvalu's rising sea level.        The average global temperature has increased by almost 0.5 centigrade degrees over the past century; scientists expect it rise by extra 1-3 degrees over the next 100 years.        Warmer weather makes glaciers  melt, and adds more water to the ocean.The warmer temperatures also make water expand, so it takes up more space, causing the sea level to rise.The sea level has risen about 10-25 cm in the last 100 years.        The main cause of global warming is human pollution.Through burning coal, oil and gas, people have been increasing the greenhouse gases in the atmosphere, such as CO2.This adds to the power of the greenhouse effect, making the planet even warmer.       Many scientists believe that, if the warming is not stopped, there will be huge climate changes.The sea level could rise by one meter this century.        Should this come true, the sea would swallow up millions of homes and the world will be flooded with "climate refugees" looking for somewhere to live. Question: What does "climate refugees" mean? Options: A: Climate changes. B: Climate effect. C: People forced away from their homeland by climate. D: Rare animals moving from place to place for climate changes.
A: C


Q: I'm taking a test and have to guess the right answer to the question after the article. Article: The prestigious   Peking University and Tsinghua University held graduation ceremonies on the same day this year. The presidents of the two universities delivered excellent speeches at the ceremonies as they used words, phrases or ways of expression that are very popular on the Internet currently. At the same time, graduation speeches by other university presidents were also under the spotlight for the same reason. Their speeches were warmly welcomed by students as they contained many fashionable words today, such as "floating clouds" ( meaning "too small and of little importance to mention") and "gelivable" (meaning " very helpful") . In the speeches , these university presidents recalled campus life together with students and finally moved all the audiences. They were very different from the usual run of lectures. Many university presidents have changed their regular manner of addressing graduation ceremonies from an advising and preaching   mode to a more fashionable and funny approach. They try to use those words popular among young people in their speeches. In the past, university presidents' speeches were criticized for being too standard and lacking sentiment. Now , they quote fashionable words in their addresses, reflecting they are starting to adopt more everyday attitudes to students. The use of these new expressions has _ a heated discussion. It focuses on the question of whether university presidents should speak in an informal way at graduation ceremonies. Supporters agree with the new approach. They consider it good to build close ties with students by using the youth's own words. Opponents argue the new ways have no practical value or significance for education but are merely to please those leaving university. Question: What would be the best title for this passage? Options: A: Should University Heads Use Terms of Youth B: Must University Presidents Learn to Please Students C: Must University Presidents Meet Students' Needs D: Should University Heads Use Newly-created Words
A: A


Q: I'm taking a test and have to guess the right answer to the question after the article. Article: A qualified doctor who rarely practiced but instead devoted his life to writing. He once said: "Medicine is my lawful wife, and literature is my lover." Russian writer Anton Pavlovich Chekhov, was a great playwright and one of the masters of the modern short story. When Chekhov entered the Moscow University Medical School in 1879, he started to publish hundreds of comic short stories to support his family. After he graduated, he wrote regularly for a local daily newspaper. As a writer he was extremely fast, often producing a short story in an hour or less. Chekhov's medical and science experience can be seen through the indifference  many of his characters show to tragic events. In 1892, he became a full time writer and published some of his most memorable stories. Chekhov often wrote about the sufferings of life in small town Russia. Tragic events control his characters who are filled with feelings of hopelessness and despair. It is often said that nothing happens in Chekhov's stories and plays. He made up for this with his exciting technique for developing drama within his characters. Chekhov's works combined the calm attitude of a scientist and doctor with the sensitivity  of an artist. Some of Chekhov's works were translated into Chinese as early as the 1940s. One of his famous stories, The Man in a Shell, about a school teacher's extraordinarily orderly life, was selected as a text for Chinese senior students. Question: Anton Pavlovich Chekhov   _  . Options: A: had a lawful lover B: was an illegal writer C: used to be a lawyer D: was a competent doctor
