Yet evidence suggests that most of us don't use the learning techniques that science has proved the most effective. The scientific literature evaluating these techniques goes back to decades and across thousands of articles. It's far too _ and complex for the average parent, teacher or employer to look through. Fortunately, a team of five leading psychologists have done the job for us. Professor John Dunlosky and other psychologists closely examined 10 learning strategies and rated each from high to low utility on the basis of the evidence they've gathered. Here's part of their conclusions: In contrast to familiar practices, the effective learning strategies with the most evidence to support them aren't well known outside the lab. Take distributed practice, for example. This strategy involves spreading out your study time, rather than engaging in one marathon. Cramming information at the last minute may allow you to get through that test or meeting, but the material will quickly disappear from your memory. It's much more effective to look through the material at intervals over time. And the longer you want to remember the information, whether it's two weeks or two years, the longer the intervals should be. The second learning strategy that is highly recommended by Dunlosky is practice testing. Yes, more tests---but there not for a grade. Research shows that the mere act of calling information to mind strengthens that knowledge and aids in future retrieval . While practice testing is not a common strategy---despite the strong evidence supporting it ---there is one familiar approach that captures its benefits: using flash cards. And now flash cards can be presented in digital form. Both distributed practice and practice testing were rated as having "high utility" by Dunlosky. Question: How did the psychologists study and rate the learning strategies? Options: A: By analyzing the materials gathered in the past years. B: By asking some students questions about their study. C: By doing some experiments on the objects in the lab. D: By asking parents and teachers to look through the articles.

Read the article and select the best answer. Article: Last week, President Barack Obama gave a back- to-school speech to students at the Julia R. Masterman Laboratory and Demonstration School in Philadelphia, Pennsylvania. Students in schools across the country also tuned in to watch the President's speech on TV. He stressed the importance of trying new things, working hard and believing in yourself. While admitting that times are tough for families across the country, Obama reminded students that hard work now can mean big success later. "Nobody gets to write your destiny but you," he said. "Your future is in your hands. Your life is what you make of it. And nothing--absolutely nothing--is beyond your reach." Obama spoke about his own life, and lessons he learned from his mother, who had to remind him to stay focused on his studies. He told students the recipe for success: "Showing up to school on time. Paying attention in class. Doing your homework. Studying for exams. Staying out of trouble. " Obama encouraged students to embrace what makes them different. "We shouldn't be embarrassed by the things that make us different," he said. "We should be proud of them." He also suggested taking advantage of all of the opportunities at your school, and always being open to trying new things. "Just because you're not the best at something today doesn't mean you can't be tomorrow," he said. "Even if you don't think of yourself as a math person or as a science person--you can still _ those subjects if you're willing to make the effort. And you may find out you have talents you'd never dreamed of." Question: Obama suggested the students should _ . Options: A: not study hard for high marks B: accept things that make them different C: do what they are really interested in D: not do things which are difficult for them

Ques: Read the article and select the best answer. Article: TOKYO--Lonely astronauts on the International Space Station (ISS) may soon be getting a robot friend from Japan. Japan's space agency is considering putting a talking humanoid robot on the ISS to watch the work while astronauts are asleep, monitor their health and stress levels and communicate to Earth through the microblogging site Twitter. Japan's space agency JAXA announced this week that it is looking at a plan to send a humanoid robot to the space station in 2013 that could communicate with the ground through Twitter--primarily feeding photos, rather than original ideas --and provide astronauts with "comfort and companionship". Following up on US NASA's "Robonaut" R2 program, which is set for launch on the Discovery shuttle next week, the Japanese robot would be part of a larger effort to create and refine robots that can be used by the elderly, JAXA said in a statement. Japan is one of the leading countries in robotics and has a rapidly aging society with one of the world's longest life expectancies. Improving robot communication capabilities could help elderly people on Earth by providing a nonintrusive means of monitoring the robot owner's health and vital signs and sending information to emergency responders if there is an abnormality, JAXA said. "We are thinking in terms of a very humanlike robot that would have facial expressions and be able to talk with the astronauts," said JAXA's Satoshi Sano. The robot was being developed with the advertising and communications giant Dentsu Inc and a team at Tokyo University. The NASA project has a humanlike head, hands and arms and uses the same tools as station crew members. The "Robonaut" called R2 is intended to carry out maintenance tasks in the station's Destiny lab. NASA says it hopes that humanoid robots could one day stand in for astronauts during spacewalks or perform tasks too difficult or dangerous for humans. For now, the $2.5 million NASA robot is limited to activities within the lab. Question: According to the passage, a humanoid robot, put on the ISS, shall carry out the tasks except _ . Options: A: keep in contact with Earth B: get a friend for astronauts from Japan C: take care of the ISS sometimes D: keep an eye on the health of the astronauts
Ans:
B
