Women who own cats are more likely to have mental health problems and kill themselves because they can be infected by a common parasite that can be caught from cat litter, a study has found. Researchers found women infected with the Toxoplasma gondii (T. gondii) parasite , which is spread through contact with cat waste or eating undercooked meat or unwashed vegetables, are at increased risk of attempting suicide. The study involved more than 45,000 women in Denmark. About a third of the world's population is infected with the parasite, which hides in cells in the brain and muscles, often without producing symptoms. The infection, which is called toxoplasmosis , has been linked to mental illness, such as schizophrenia , and changes in behavior. The study's senior author Doctor Teodor Postolache, an associate professor of psychiatry  at the University of Maryland School of Medicine in the United States, said, "We can't say with certainty that T. gondii caused the women to try to kill themselves, but we did find a predictive association between the infection and suicide attempts later in life that deserves additional studies." Doctor Albert Reece, vice president of medical affairs at the University of Maryland, said, "T. gondii infection is a major public health problem around the world, and many people don't realize they're infected. "Dr Postolache is a leading expert on suicide neuroimmunology . Suicide is a critically important mental health issue. About one million people commit suicide and another 10 million attempt suicide worldwide each year. We hope that this type of research will one day help us find ways to save many lives that now end too early in suicide." Dr. Postolache's research team at the University of Maryland was the first to report a connection between T. gondii and suicidal behavior in 2009. He is cooperating with researchers in Denmark, Germany and Sweden to confirm and investigate the way leading to this association. The T. gondii parasite thrives in the intestines of cats, and it is... The objects of the research are women from   _  . A) Demark B) the USA C) Germany D) Sweden

English has now achieved global status (position). Whenever we turn on the news to find out what's happening in East Asia, or Africa, or South America, or anywhere, local people are being interviewed and telling us about it in English. Indeed, if one looks at the facts about the amazing reach of the English language, he or she would be surprised. English is used in over 90 countries as an official or semi-official language. English is the working language of many international colleges as well as of most international research scientists. It is believed that over one billion people worldwide are learning English now. One of the most remarkable sides of the spread of English around the world has been the extent   to which Europeans are accepting it as their language. English is spreading from northern Europe to the south and is now firmly set up as a second language in countries such as Sweden, Norway, Netherlands and Denmark.

As a public school superintendent , I believe the best way to prepare students for colleges and careers is to focus on providing instructional programs and opportunities that help them become good thinkers. To do this, teachers and actually everyone else in a community, should play a role as a "cognitive coach" to students, helping develop good thinkers among our youth. The best way for you to become a cognitive coach is to seek out and engage school children and adolescents in meaningful conversations. The objective here is to get kids talking about what they think, how they feel, and what they believe whenever and wherever you may find them. It may be in a classroom. It may be at the grocery store. It may be at a basketball game. It doesn't matter where as long as you engage students in a topical conversation and, hopefully, even a debate. Mainly, you want to encourage students to voice their opinion about things. Get them to take a position on "this thing, or that thing," and ask them to support their position with evidence. Curiously enough, the simple process of engaging students in real life conversations and debates will serve to strengthen what they have learned in the classroom, and help them create their own knowledge about a subject or a topic. Learning indicates that a student has been exposed to material, understands the material, and can recall the information. Knowledge, on the other hand, goes beyond recall and includes information processing, application to other situations, consideration of meaning, and contrasting with other concepts. Naturally, the topic of conversation you engage in with one of your learners will differ from student to student, and in the level of complexity based on child's age and developmental level. Even a kindergartener has an opinion about things that are going on in his or her life. Engaging in conversation with any members of your learning community in ways that get at what they have learned and what they know will help them develop higher order reasoning... What is the main purpose of the passage? A) To state an education idea. B) To assess a teaching strategy. C) To introduce a learning method. D) To compare different education methods.
