Article: To the mom I used to be: Two years ago, you were happy and whole. You had a plan for life -- start a new business, get involved in the Parent-teacher Association, teach your sons how to ride bicycles, spend as much time with your friends and parents as possible, watch your children mature and grow old with your husband. You were a " _ " person who often felt so much joy. You always looked forward, smiled and danced. Two years ago, on December 14, 2012, the world changed and you changed with it. Disturbed young men with access to high-powered guns went to your sons' school and killed six educators and twenty first-graders. Your eldest son Jake survived, but was changed by the day he discovered some monsters are real. He describes it as the day "when evils came to my school." Your youngest son, Dylan, whom you thought of as a pure love, with his charming eyes and infectious giggle ,was killed. Shot multiple times, he died instantly in the arms of his special-education assistant who also died while trying to protect him. The tragedy changed all your life, not only because of losing your child, but because of the hole inside you that can never be filled. Your eldest son has been forced to grow up too fast because of the loss of his brother. The pain has altered the lines on your husband's face. The way you look at the world has changed. Your interactions with friends and family seem foreign. ... ... But the things have moved on with hopefulness. You are now someone far more realistic. You control your feelings because you fear if you really let it out, you would never recover. It would destroy you. You know what you should do is try everything to protect more children. You're fighting a good fight, what the whole society really needs. With love, Nicole Hockley, Dylan's mom Question: The author writes the letter mainly to _ .

Article: Very old people do raise moral problems for almost everyone who comes in contact with them. Their values--this can't be repeated too often--are not necessarily our values. Physical comfort, cleanness and order are not necessarily the most important things. The social services from time to time find themselves faced with a flat with decaying food covered by small worms , and an old person lying alone in bed, taking no notice of the worms. But is it interfering with personal freedom to insist that they go to live with some of their relatives so that they might be taken better care of? Some social workers, the ones who clear up the worms, think we are in danger of carrying this concept of personal freedom to the point where serious risks are being taken with the health and safety of the old. Indeed, the old can be easily hurt or harmed. The body is like a car, it needs more mechanical maintenance as it gets older. You can carry this comparison right through to the provision of spare parts. But never forget that such operations are painful experiences, however good the results. And at what point should you stop treating the old body? Is it morally right to try to push off death by pursuing the development of drugs to excite the forgetful old mind and to activate the old body, knowing that it is designed to die? You cannot ask doctors or scientists to decide, because so long as they can see the technical opportunities, they will feel bound to give them a try, on the principle that while there's life, there's hope. When you talk to the old people, however, you are forced to the conclusion that whether age is happy or unpleasant depends less on money or on health than it does on your ability to have fun. Question: In the author's opinion, _ . Yes or no, is the answer "the older a person, the more care he needs"?
(Answer)
No

Ques: Article: Teens are more likely to behave badly if their parents expect them to,a new US study has found. "Parents who believe they are simply being realistic might actually be having a bad effect on their children," Christy Buchanan,a teacher at Wake Forest University and one of the authors of the study,said. "Bad expectations on the part of both parents and children predict more rebellious behaviors later on." The finding came from a study of more than 250 sixth and seventhgraders and their mothers. They were examined at the start of the study and again one year later. If kids' mothers expected them to take more risks and be more rebellious,higher chances of risky behavior were seen. _ _ _ when kids had bad expectations of themselves. "Sometimes parents expect more negative behavior from their children than they should based on the children's history of behavior," Buchanan said.Parents shouldn't be naive about the possibility of bad behavior,she said,but it's also a mistake to think that children who are wellbehaved will naturally become rebellious at the age of 13. "By thinking risktaking or rebelliousness is normal for teenagers and showing that to their children,parents might add to other messages from society that make teenagers feel that they are strange if they are not willing to take risks or break laws," she said."This can mean,for example,that when parents expect teens to drink before they turn 21 or to do other risky behaviors,kids are less likely to refuse to do so later in their lives." On the other hand,parents' expectations that teens can exhibit good behaviors and refuse to behave badly or to take risks could help reduce the possibility of bad behavior,Buchanan said."As a parent,you should put expectations on your children carefully." Question: What do we know about the study? Yes or no, is the answer "Participants were examined twice."?
Ans: Yes

Question: Article: When you hear the word "farm", chances are you picture rolling hills in the country covered with cows and cornstalks. Some scientists, engineers and city planners say the farms of the future could rise straight into the air---in skyscrapers in the world's most populated cities. It might sound far--fetched, but in fact, some of the technology for growing crops indoors already exists. The scientists at the South Pole research station enjoy fresh salads every day from vegetables they grow in their own greenhouse. And NASA has been experimenting for years with methods for growing fresh fruits on the moon or even on Mars. As is known, traditional farming takes a plot of land as big as the entire state of Virginia just to grow enough food for 8 million people, says ecologist Dichson Despommer. Cities that can't grow their own food are often influenced by disasters such as hurricanes that can make it impossible for trucks to deliver fresh produce to grocery stores. In addition, fruit and vegetables grown outdoors face all kinds of dangers, from flooding to insect pests to weather instability, such as late or early frosts that can damage a crop. "You can control everything indoors. You can't control anything outdoors," Despommier says. To top it off, by the year 2050, the world population will grow by another 3 billion. "Where will we grow the food for all these people?" Vertical farming----growing crops in skyscrapers, tens of stories high----is the answer," says Despommier. Others say _ could provide new uses for hundreds of abandoned buildings in cities around the world. Crop waste, like leaves, would be composted , and the gases given off from composting would be used to heat the building. "I'd say it is going to be tough," says agriculturist Giacomelli. It can be tricky to regulate climate conditions indoors. Plus, plants differ in their weather and lighting requirements. Tomatoes like warm, sunny weather, while greens like lettuce prefer cooler temperatures. And nearly all crop plants require... Question: What attitude does Giacomelli have towards the vertical farming? Yes or no, is the answer "Uncertain"?

No
