Ques: Read the article and select the best answer. Article: Imagine this: you get up in the morning and put on a custom printed T-shirt. Then you eat some 3-D printed food and relax on your printed sofa. Perhaps you take a ride in a printed electric car to the hospital to get a printed tooth fitted. Though some of these things may seem impossible, they're closer to reality than you might think. The world of 3-D printing is coming to a store near you soon. The idea of 3-D printing is to produce complicated shapes in a very personalized way. If you want to make a totally new object, you need to make a virtual design in a CAD(computer aided design)file first. Or you can use a 3-D scanner to make a digital copy of an object. Then, based on the design or copy, the 3-D printer makes paper-thin slices out of liquid, plastic, or metal and puts them together to create the object you want. There are many areas in which 3-D printing can change our lives. One such area is health care. Researchers have developed simple 3-D printed organs, which can be used in life-saving operations. A 17-year-old boy in the US has also recently developed a brain-powered, 3-D printed replacement hand. From heart monitors to fake limbs , we can soon be living longer thanks to 3-D printed technology. Another area that 3-D technology looks sure to change is food. Can you imagine being able to print your favorite dishes at home at the touch of a button? Even big companies are behind the trend. Hersheys, one of the largest chocolate makers in the world, recently announced that it would start producing chocolate with the help of 3-D printers. NASA, the US space agency, has reportedly spent $125,000 (767,594 yuan) developing a "3-D pizza printer". It is not yet clear how long it will take until 3-D printers are available to everyone. But one thing is for sure: the possibilities are endless. Question: We can infer from the article that _ . Options: A: there is still a long way to go before everyone can have access to 3-D printing B: 3-D printed organs and limbs are as effective as real ones C: big food companies are major players in the 3-D printing industry D: people can create any object with any material by 3-D printing
Ans: A

Ques: Read the article and select the best answer. Article: On Tuesday, the White House and the U.S. Department of Agriculture (USDA) set new limits on advertising food and drinks in schools. The rules ban advertisements for unhealthy foods in schools. The ad ban includes sugary drinks that account for more than 90% of unhealthy ads. An ad for Coca-Cola, for example, will be removed from a scoreboard at a high school football game. However, ads for Diet Coke and Dasani water, owned by the same company, are allowed to display . The new rules are part of the First Lady's "Let's Move" campaign to fight childhood obesity . Her goal is to get kids to eat healthier food. The marketing limits came after new USDA regulations that put a limit on the calorie, fat and sugar in most school food items. "The idea is simple -- our classrooms should be healthy places," the First Lady Michelle Obama said. "Because when parents are working hard to teach their kids healthy habits at home, their work shouldn't be destroyed by unhealthy messages in schools." However, the healthier food rules are criticized by people who think the government should not control what kids eat and by some students who don't like the healthier foods. It is reported that food companies spend $149 million a year on marketing foods to kids, and many big companies are supporting the new rules. Coca-Cola and PepsiCo have started to advertise healthier products. For schools, junk food ads like the Coca-Cola scoreboard will be taken down. "The new limits ensure that schools remain safe places where kids can learn and eat healthy food," Agriculture Secretary Tom Vilsak said. The rules will help guide schools on ways to create standards for foods and physical activities. They will require parents and the community to be involved in the campaign. Question: What's the main idea of the text? Options: A: Having a balanced diet in schools is important. B: New limits on advertising foods in schools have been set. C: It's Michelle's duty to make sure schools are safe places. D: Banning advertisements for Coca-Cola in schools is necessary.

Ques: Read the article and select the best answer. Article: Many grown-ups worry that spending too much time playing video games isn't good for a kid's health. But some doctors have noticed that kids who bring their game players to the hospital seem less worried about being there. They also seem to feel less pain when they are giving all their attention on a car race or other games. At a children's center in Baltimore, Maryland, young kids are finding hospital visits easier to deal with, thanks to a test program called HOPE. Patients in HOPE have a life-threatening condition where their kidneys no longer get rid of wastes from their blood. To get their blood cleaned, these kids must use the dialysis machines at the hospital three times a week, for at least three hours each time. HOPE allows kids to play Internet sports, racing, and other games with each other. They will be able to connect with kids in other hospitals who have the same problem. "We want to use the Internet to bring together kids who are ill, and let them know they are not alone," said Arun Mathews, the doctor of the program. He loved video games himself and got the idea to connect kids all over the country. Many researchers elsewhere are testing video programs that might help young patients. For example, nine-year-old Ben Duskin of San Francisco, California, who was struggling with cancer helped to design a video game where players got rid of cancer cells. That's all great news, because doctors already know that reducing pain and worry helps patients heal faster. Question: Which can be the best title for the passage? Options: A: Video Games Are Bad for Health B: Video Games May Help Reduce Pain C: A Famous American Organization D: HOPE Allows Kids to Play Online Games
Ans: B

Ques: Read the article and select the best answer. Article: People in the United States honor their parents with two special days: Mother's Day, on the second Sunday in May, and Father's Day, on the third Sunday in June. Mother's Day was proclaimed a day for national observance by President Woodrow Wilson in 1915. Ann Jarvis from Grafton, West Virginia, had started the idea to have a day to honor mothers. She was the one who chose the second Sunday in May and also began the custom of wearing a carnation. In 1909, Mrs. Dodd from Spokane, Washington, thought of the idea of a day to honor fathers. She wanted to honor her own father, William Smart. After her mother died, he had the responsibility of raising a family of five sons and a daughter. In 1910, the first Father's Day was observed in Spokane. Senator Margaret Chase Smith helped to establish Father's Day as a national commemorative day, in 1972. These days are set aside to show love and respect for parents. They raise their children and educate them to be responsible citizens. They give love and care. These two special days are celebrated in many different ways. On Mother's Day people wear carnations. A red one symbolizes a living mother. A white one shows that the mother is dead.Many people attend religious services to honor parents. It is also a day when people whose parents are dead visit the cemetery.
