While posing in our costumes the night before, we knew something was wrong, just not how wrong. Grandma's house was the central gathering place of my family. Sunday lunches, birthday dinners, Easter, Thanksgiving, and Christmas -- all were our traditions, with her as hostess. While my parents were busy running their small business, there were many nights when Grandma fed me and put me to bed in her spare room, until they came to get me. I spent my summers at Grandma's and I went everywhere with her. I couldn't imagine a time when she wouldn't be around me. Then November 1, 1991 began her month-long stay in the hospital--she suffered from a rare infection called nocardia asteroides. After being born in the year of the Great Depression, living through World War II, raising three kids, and being widowed at the age of 48, Grandma never expected to live into her seventies. The infection in her brain seemed to confirm that she wasn't long for this world. But that's not the end of her story. A team of doctors successfully removed the abscess , and Grandma even made it into a local medical journal. Her doctor called her "the brain lady". Grandma celebrated her 85thbirthday in March this year. In the almost 23 years since her recovery, she's seen two of her four grandchildren get married and welcomed three great-grandsons. Although they damage something in her house, she loves it when my two boys come over. And while I know they make her day, seeing her love blossom for another generation makes my day too. Happy Grandparents' Day to my amazing grandmother! Question: The author wrote this text _ . Options: A: in honor of Grandma B: to promote Grandparents' Day C: to stress the importance of health D: in celebration of Grandma's recovery

Article: The Vienna-based researchers showed that dogs will stop doing a simple task when not rewarded if another dog, which continues to be rewarded, is present. The experiment consisted of taking pairs of dogs and getting them to present a paw for a reward.On giving this "handshake" the dogs received a piece of food.One of the dogs was then asked to shake hands, but received no food.The other dog continued to get the food when it was asked to perform the task. The dog without the reward quickly stopped doing the task, and showed signs of anger or stress when its partner was rewarded. To make sure that the experiment was really showing the interaction between the dogs rather than just the frustration of not being rewarded, a similar experiment was conducted where the dogs performed the task without the partner.Here they continued to present the paw for much longer. Dr Frederike Range from the University of Vienna says this shows that it was the presence of the rewarded partner that was the greater influence on their behaviour. "The only difference is one gets food and the other doesn't, they are responding to being unequally rewarded." she said. The researchers say this kind of behaviour, where one animal gets frustrated with what is happening with another, has only been observed in primates before. Studies with various types of monkeys and chimpanzees show they react not only to seeing their partners receiving rewards when they are not, but also to the type of reward. The dog study also looked at whether the type of reward made a difference.Dogs were given either bread or sausage, but seemed to react equally to either.Dr Range says this may be because they have been trained. Question: What would the dogs do if they presented their paw alone? Options: A: They would go on with the performance much longer. B: They would be too shy to present their paw. C: They would miss their partners. D: They would compare what they got with that of others.

Article: One advantage of the Internet is shopping conveniently online for clothes; one disadvantage of the Internet is also shopping conveniently online for clothes. "Nothing fits," said Lam Yuk Wong, a senior in electrical and computer engineering at Rice University. "Everyone says this. They order clothes and they don't fit. People get very unhappy." Wong and her design partner, Xuaner "Cecilia" Zhang, are Team White Mirror, creators of what they call a "virtual fitting room". Their goal is simple and consumer-friendly: to let online clothing shoppers have a perfect fit and a perfect look when shopping every time. Both women are from China, Wong from Hong Kong and Zhang from Beijing. They both order most of their clothing online. They got the idea from their own experience as consumers and from listening to the complaints of friends and relatives. "They say, 'The color is wrong' or 'I got the right size but it still does not fit.' We want to make it like you're in the store trying on the clothes," Zhang said. Using a Kinect developed by Microsoft for use with its Xbox 360 video game player, Zhang scans Wong and turns her image into, in effect, a virtual model, keeping Wong's dimensions , and even her skin and hair color. "We put the clothes on the shopper's 3-D body models and show how they look when they are dressed," Wong said. So far, Wong and Zhang have adapted the software to show dresses and shirts, and they are now working on shorts. Asked if she thought men as well as women might be interested in using their virtual fitting room, Wong said, "I think their wives will care about this, so it will also be important to men." Question: Why is shopping conveniently online for clothes a disadvantage? Options: A: Students may easily get addicted to it. B: Clothes bought online may not fit. C: It attracts more online clothing shoppers. D: It causes shoppers to waste too much money.
