Read the article and select the best answer. Article: For thousands of years, people have seen things they didn't understand in the sky. The United States Air Force first used the words "Unidentified Flying Object" to describe them. Today everyone uses the term UFO. When people see a UFO, it is usually no more than a weather balloon or an airplane. But the Center for UFO Studies goes on to receive hundreds of reports each year. In 1947 a businessman and pilot, Kenneth Arnold, was flying near Mount Rainier, Washington when he saw nine shiny, round objects flying through the air. He told a newspaper reporter they looked like "pie plates skipping over water." The reporter used the words "flying saucer " in his story and today that is the popular name for UFOs. The Center for UFO Studies lists three kinds of contacts with flying saucers. "Encounters of the first kind" are reports of unknown objects or lights in the sky. People have "Encounters of the second kind" when a UFO leaves burn marks or other signs on the ground. People report "Close encounters of the third kind" when they see aliens in or near a UFO. Question: Why did the newspaper reporter use the words "flying saucer" to describe the UFO that Kenneth Arnold said he saw? Options: A: Because the UFO that Kenneth Arnold saw was flat. B: Because Kenneth Arnold told the newspaper that what he had seen in the sky was round. C: Because Kenneth Arnold described what he has seen looked like a plate flying in the sky. D: Because what Kenneth Arnold saw was pie plates flying in the air.

The heart doctors can use the models to better help patients before an operation. Dr. Bramlet, a children's heart expert at the University of Illinois College of Medicine, says the 3-D models show information he cannot get any other way. "And so what we've done with the printed models? We've pulled it out of the screen so that you can actually hold it in your hand and evaluate the anatomy ." A 3-D printer uses images from a digital display to create a physical model of a human heart. Matthew Bramlet says doctors can use the model to understand the anatomy. Pictures from medical tests like CAT scan or MRI are sent to a 3-D printer to create a heart in a plaster form. The printer then constructs the heart, thin layer by thin layer. Dr. Bramlet says the model matches the real heart in every detail. "When we're done with the model and made our decision, we want to be able to go back to the source image and confirm those findings," he says. Dr. Bramlet has built model hearts for different kinds of heart operations. All of the operations were successful. In his first case, digital images showed only one tiny hole in a baby's heart. But, the 3-D printed model showed several defects or problems that the baby was born with. Dr. Bramlet says those defects could not be seen easily in the images. The heart surgeon was able to change the type of surgery for the patient based on the 3-D model. He added that 3-D heart models saves time during heart operations. Kathy Magliato is a heart surgeon at Saint John's Health Center in Los Angeles. She welcomes the new technology. She says it could help her make better decisions before she operates on the hearts of her patients. "I can then take this very complicated structure before the operation and I can hold it in my hand and plan an operation around what I'm seeing, touching and feeling. That to me is what can potentially change the game in an operation and save lives." Dr... Question: What is the biggest advantage of 3-D models in the diagnose of heart problems? Options: A: Surgeons can see, touch and feel the 3-D models. B: They can help surgeons save time. C: They can be made exactly like the hearts. D: They can help discover the otherwise hidden heart problems.

Read the article and select the best answer. Article: Parents everywhere praise their kids when they do well in school, win a ball game, or build an impressive sandcastle --- anytime their kids do something remarkable , or in many cases, something ordinary. "We are becoming praise junkies as parents", says Jenn Berman, PhD, a marriage and family expert and the author of The A to Z Guide to Raising Happy and Confident Kids. "We have gone to the opposite extreme of the parents from a few decades ago who tended to be more strict, and now we overpraise our children." "Somehow parents have come to believe that by praising our kids we improve their self-esteem ," says Paul Donahue, founder and director of Child Development Associates. "Though well-intentioned, putting kids on a pedestal at an early age can actually hinder their growth." Too much praise can backfire , it seems, and when given in a way that's insincere, kids are afraid to try new things or take a risk for fear of not being on the top all the time. "There's an underlying message that the child has to get his parents' approval all the time and constantly depends on the parents for validation ," says Berman. Still, don't go too far in the other direction --- not giving enough praise which can be just as damaging as giving too much. Kids will feel like they are not good enough, or that you don't care, and may see no sense in reaching for their success. So what's the right amount of praise? Experts say that the quality of praise is more important than the quantity: if praise is sincere and genuine, and focused on the effort, not the outcome, you can give it as often as your child does something that is worth a reward. Question: What kinds of parents can be regarded as praise junkies? Options: A: Those who praise their children too much. B: Those who seldom praise their children. C: Those who give sincere praise to their children. D: Those who offer their children dangerous drugs.
