Question: Article: Adding math talk to story time at home is a winning factor for children's math achievement, according to a new research from the University of Chicago. The study from psychologists Sian Beilock and Susan Levine shows a marked increase in math achievement among children whose families used Bedtime Math, an iPad app that delivers engaging math story problems for parents and children to solve together. Even children who used the app with their parents as little as once a week saw gains in math achievement by the end of the school year. The app's effect was especially strong for children whose parents tend to be anxious or uncomfortable with math. Previous research from this group has demonstrated the importance of adults' attitudes about math for children's math success. For example, a recent study found that math-anxious parents who help their children with math homework actually weaken their children's math achievement. The new findings demonstrate that structured, positive interactions around math at home can cut the link between parents' uneasiness about math and children's low math achievement. "Many Americans experience high levels of anxiety when they have to solve a math problem, with a majority of adults feeling at least some worries about math," said Beilock, professor in Psychology and author of Choke, a book about stress and performance. "These math-anxious parents are probably less likely to talk about math at home, which affects how competent their children are in math. Bedtime Math encourages a dialogue between parents and kids about math, and offers a way to engage in high-quality math interactions in a low-effort, high-impact way." Study participants included 587 first-grade students and their parents. Families were given an iPad installed with a version of the Bedtime Math app, with which parents and their children read stories and answer questions involving math, including topics like counting, shapes and problem-solving. A control group received a reading app that had similar stories without the math content and questions related to reading comprehension instead. Children's math achievement was assessed at the beginning and end of the school year. Parents completed a questionnaire about their nervousness with math. The more times parents and children in the math group used the app, the higher children's achievement on a math assessment at the end of the school year. Indeed, children who frequently used the math app with their parents outperformed similar students in the reading group by almost three months in math achievement at year's end.

Answer: D

Question: Article: Roughly speaking, teachers in traditional education may feel that students are too young to know much about the world, and have to be told what to do most of the time. By contrast, open education offers teachers quite different feelings. Students are expected to be responsible for their own education--to discover subjects by themselves instead of being made to study them. This way of teaching allows the students to grow independently and to develop their own interests in many subjects. Some students who do badly in a traditional classroom will be happier in an open classroom and enjoy learning. They will not have to worry about grades or rules at all. However, many students won't do well in an open classroom. For these students, they will do little in school if there are too few rules. They will not make good use of open education, which is so different from traditional class, because they may have a problem getting used to making so many choices on their own. For them it is important to have some rules to direct them. They may worry about the rules even when there are no rules. In addition to that, some traditional teachers do not believe in open education and do not like it either. Since both of some good points and bad points of the open education have been explained clearly, you may have your own opinion on the issue. Personally, I think that the concept of open education is good only in theory. In actual fact, it may not work very well in a real class or school. I believe, most students, but of course not all students, need some structure in their classes. They may want and need to have rules. In some cases, they must be made to study some subjects. Many students are pleased to find subjects they have to study interesting. They would not study those subjects if they did not have to.
Question: Open education allows the students to _ .
Options: (A) grow as the educated (B) be responsible for their life (C) discover subjects outside class (D) develop their own interests

Answer: D

Question: Article: When I was 13, my bedroom walls were covered with posters of the Monkees and Beatles. I wrote fan letters and daydreamed about meeting the objects of my affections. I begged my parents to attend every rock concert and watch every TV show featuring my favorite celebrities; my friends and I discussed for hours all the things we would say and do when we met our favourite movie stars and pop singers. I drove my mother crazy ! But after a few years, my obsession stars faded as I matured and gained the confidence to socialize with "real" boys. In the 35 years since I was a teenager, celebrity worship has increased among teens due to the explosion of television celebrity gossip shows, and instant access to celebrity news on the Internet. It's no wonder that many teens are obsessed with stars when news programs are often filled with entertainment stories and the lives of celebrities. Celebrity worship syndrome is now considered a personality disorder. While it is normal for teenagers to follow the lives of their favorite stars, parents should try to monitor everything their child finds interesting. Parents should take action if they suspect a teen is too obsessed with celebrities and showing little interest in school or withdrawing from the family. When teens talk a lot about celebrities and view them as just means of entertainment, this is considered normal celebrity worship. However, when a teenager is obsessed with a star and often expresses a desire to have a close personal relationship with a celebrity or feels they have a special connection to a star, this may be the time for concern. Recent studies have shown that teens who develop an unhealthy obsession with celebrities often suffer from low self confidence and depression. Teens who are overly obsessed with stars often have damaged relationships with their parents.

Options: (A) talk a lot about celebrities with others (B) put up celebrity posters in their bedrooms (C) ask to go to their favourite star's concert (D) desire a close personal relationship with their favorite star
