Article: The gray-haired lady can't wait to leave the building to search for her dad. Unless watched, she will walk in the streets in an effort to find her father, who died 30 years ago. Not all cases of Alzheimer's disease  look like this, but Alzheimer's is a serious disease that is said to be the fourth or fifth leading cause of death for people over age 75. It is said that about three percent of the U.S. population over age 65 have Alzheimer's. In the early stages, people may exhibit short-term memory loss. Some may experience changes in personality, easy to be angry. As the disease progresses, patients might lose the ability to move and may be unable to speak or move at all. This progressive disease generally lasts 8 to 10 years before death occurs. While no one is certain what causes these changes in the brain's nerve fibers  , their effect is certain. Alzheimer's destroys not only the patients, but also spouses , friends and families. What should you do if you notice progressive memory loss in yourself or a loved one? Have the person examined by a doctor who is a specialist in the treatment of Alzheimer's disease? Though many reasons other than Alzheimer's disease may cause memory loss, its early diagnosis and treatment may delay some of the most serious effects. What feeling will you likely experience if a loved one suffers from Alzheimer's disease? A person will often go through the various stages of sadness, shock, anger, and so on. If the spouse develops the disease, you may experience hurt and disappointment when he or she doesn't remember you are married. Life for the Alzheimer's patients and their loved ones will never be the same as the disease progresses, bringing a deep sorrow, loss and even anger towards God. No matter what feelings are present, facing them honestly will serve one better than burying them.

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.

Article: Tanzania Tarangire is a national Park which lies in Tanzania. The park itself covers an area of around 2,850 square kilometers, making it the sixth largest park of its kind in the country. I recently visited Tarangire to see what it was like.... One of the first sightings upon entering the park which I found was a huge herd of elephants.  Our guide told us that Tagrangire was probably the best place in Tanzania to find large herds of elephants, and that their population in the park was around 2,500. We continued to watch the elephants as they stood under trees and scratched themselves against the trees to hit the spot of an itch . To the right of the elephant herd, we noticed a big tree! Our guide informed us that this was a Baobab tree and that they could live for hundreds of years. Compared with this tree, the elephant just looked like dwarfs ! We were informed that Tarangire was one of the best National Parks in Africa to see so many Baobab trees. As we continued our drive through the park, we finally reached a watering hole. Our guide warned us that there were lions all around us. It took us all a while to find them, but there they were! Most of them are resting in the shade under brushes, but there was one that was drinking from the watering hole directly in front of us. We then noticed just to our right, there were a couple of fresh zebra corpses -- it seemed as if the lions which were resting had killed them! We were unlucky not to have seen the actual kill, as our guide had mentioned that the zebra corpses were fresh and the kill had occurred within the last hour. Our final big sighting was one that none of us were expecting to see, even our guide! We pulled over to where there was a large gathering of cars, with a sleeping leopard there! We took photos happily and excitedly and observed its surprising body before returning to our hotel as it was getting late. So, I hope you enjoyed my description of Tarangire, and that I have inspired you to add this amazing park to your very own Tanzania travel route.
