Q: Article: "A very disruptive six-year-old child kicked my legs and clawed at my hand," said one teacher. " I broke up a fight and was kicked between my legs," said another. Many people have heard stories like this. But the situation is more worrying still and it involves parents. Every child, regardless of the circumstances into which they are born, has the right to achieve their potential, regardless of their parents' wealth and class. And we recognize that, as a nation, it is a long way to achieve this goal. But with rights come responsibilities and what worries people is that we are in danger of ignoring the latter. Far too many children are behaving badly at school, even to the point of being violent to staff. This is terrible enough, but it is hard to be surprised since many children are just mirroring the behaviour of their parents. My members tell me that parents also come into school often and threaten staff and some staff have been attacked by a pupil's parents. One father encouraged his child to start a fight on the playground before school started. A primary teacher reported that a parent shouted at him. We need to have a serious and sensible debate about the roles and responsibilities of parents and the support that they can reasonably expect of schools and teachers. Children will not learn how to behave as social beings if they are stuck in front of the TV for hours every day. They need their parents to show an interest in them and to spend time with them, helping them to play with their peers and to learn the rules of social behavior. Children are now arriving at school socially undeveloped, increasingly unable to dress themselves, unable to use the toilet properly, unable to hold a knife and fork and unused to eating at a table, Mary Bousted, general secretary of the Association of Teachers and Lecturers, writes in today's Observer. Instead of taking responsibility themselves, too many parents expect teachers to control their children's behaviour and wellbeing, she adds. Bousted says one mother blamed staff when she discovered that her 16-year-old son was smoking. We are in danger of becoming a nation of _ . The bedroom, once a place to sleep, has become the living space for the young. Spending hours in front of computer screens, on social networking sites or being immersed in computer games, children and young people spend little time with their parents. Parents are unable to monitor just what their children are watching. Schools cannot right the wrongs of society and teachers cannot become substitute parents. Both parties need to work together. Parents must be helped and given confidence to take back control. They are responsible for setting boundaries for their children's behaviour and sticking to those boundaries. They are responsible for setting a good example to their children and for devoting that most precious of resources -- time -- so that children come to school ready and willing to learn.
Question: In the opinion of the writer, what problem do people ignore?
Options: (A) The violence in the school (B) The study pressure of students. (C) The responsibilities of the students (D) The right to achieve students' potential.

Q: Article: When people who are nature lovers worldwide wish all humans to realize the importance of their natural surroundings, many Australians are turning caring for the environment into a way of life. Julie, an Australian housewife in Brisbane is one such example. Even though autumn is approaching Australia's Brisbane in April, one can still watch colorful blooming flowers in Julie's little garden, as she tells that in her community,"Each of us has a beautiful yard. The whole community, from children to elderly people, takes care of the environment as if they are taking care of their own garden." "Gardening is the most popular club in our community," she says. "A lot of retired people don't just regularly organize gardening lectures, but also personally visit families in the community to provide gardening training. So you can see that flowers continue to blossom in our gardens throughout the year." Talking about her people's sense of caring for the environment, Julie says when people in the community take along their dog, they always carry a garbage bag to deal with the dog's waste. "In our community, you will never experience the embarrassment of stepping on the dirty waste while you are walking on the grass," says Julie with a smile. "Taking care of the dog's waste can also help to develop children's sense of responsibility!" As to protecting water resources, the Australian government has made strict rules for families. Julie says, "We certainly would not use tap water to water the flowers!" She says almost every family in her community has a huge tank used to store rainwater, which is later used as the resource of all outdoor water use, including car washing and watering the garden. This year, they also asked people to connect the water tank with their toilets.
Question: Why can flowers be seen all year round in Julie's community?
Options: (A) Families are taught how to take care of their gardens. (B) Gardening lessons are often given by professors. (C) The local government provides free gardening training. (D) There is enough rainwater to water the flowers regularly.

A: A

Q: Article: Scientists have devised a way to determine roughly where a person has lived using a strand of hair, a technique that could help track the movements of criminal suspects or unidentified murder victims. The method relies on measuring how chemical variations in drinking water show up in people's hair. "You're what you eat and drink, and that's recorded in your hair," said Thure Cerling, a geologist at the University of Utah. While U.S diet is relatively identical, water supplies vary. The differences result from weather patterns. The chemical composition of rainfall changes slightly as rain clouds move. Most hydrogen and oxygen atoms in water are stable, but traces of both elements are also present as heavier isotopes . The heaviest rain falls first. As a result, storms that form over the Pacific deliver heavier water to California than to Utah. Similar patterns exist throughout the U.S. By measuring the proportion of heavier hydrogen and oxygen isotopes along a strand of hair, scientists can construct a geographic timeline. Each inch of hair corresponds to about two months. Cerling's team collected tap water samples from 600 cities and constructed a map of the regional differences. They checked the accuracy of the map by testing 200 hair samples collected from 65 barber shops. They were able to accurately place the hair samples in broad regions roughly corresponding to the movement of rain systems. "It's not good for pinpointing ," Cerling said. "It's good for eliminating many possibilities." Todd Park, a local detective, said the method has helped him learn more about an unidentified woman whose skeleton was found near Great Salt Lake. The woman was 5 feet tall. Police recovered 26 bones, a T-shirt and several strands of hair. When Park heard about the research, he gave the hair samples to the researchers. Chemical testing showed that over the two years before her death, she moved about every two months. She stayed in the Northwest, although the test could not be more specific than somewhere between eastern Oregon and western Wyoming. "It's still a substantial area," Park said "But it narrows it way down for me."
Question: What is the scientists' new discovery?
Options: (A) One's hair growth has to do with the amount of water they drink. (B) A person's hair may reveal where they have lived. (C) Hair analysis accurately identifies criminal suspects. (D) The chemical composition of hair varies from person to person.
