But now teachers in Germany are scared, too, as they are being graded by their students. Many teachers are opposed to it. They don't mind being evaluated . But they are upset because the results are then being posted on the Internet and accessible to millions of Internet users. On the websitewww.spickmich.deduring the past four months students have posted evaluation of 100,000 teachers. The teachers are graded on categories such as "motivated", "good instruction", "easy examinations", or even "sexy". Many teachers think that their privacy has been violated. The creators of the website say that the students are only being offered the chance to provide teachers with some feedback about their classroom instruction. Bernd Dicks, who founded the website with three friends, says that the students are largely quite satisfied with their teachers. On a grading scale of one to six, the teachers' average grade is 2.7 and it has been improving lately. He often says the impression is that students are bullying their teachers. But there is also bullying of the students by teachers. "Teachers must also learn to live with criticism," he added. But still, the website is not totally immune from manipulation , as one teacher near the northern city of Hanover recently proved. He registered himself on the website as a student and then rated his own teaching colleagues highly. Within a few days, seven of his colleagues were listed in the top 10 ranking of Germany's best teachers. Question: Many teachers are opposed to the website because _ . - their privacy has been violated - they are afraid of being assessed - their evaluations are unfair - the results are not satisfying
their privacy has been violated

Read the following article and select the best answer. Article: If you don't have a college degree, you're at greater risk of developing memory problems or even Alzheimer's . Education plays a key role in lifelong memory performance and risk for mental disorder, and it's well documented that those with a college degree possess a cognitive advantage over those less educated in middle and old age. Now, a large national study from Brandeis University published in the American Journal of Geriatric Psychiatry shows that those with less schooling can significantly make up for poorer education by frequently engaging in mental exercises such as word games, puzzles, reading, and lectures. "The lifelong benefits of higher education for memory in later life are quite impressive, but we do not clearly understand how and why these effects last so long," said lead author Margie Lachman, a psychologist. She suggested that higher education may encourage lifelong interest in cognitive efforts, while those with less education may not engage as frequently in mental exercises that help keep the memory agile . But education early in adulthood does not appear to be the only route to maintain your memory. The study found that intellectual activities undertaken regularly made a difference. "Among individuals with low education, those who are engaged in reading, writing, attending lectures, doing word games or puzzles once a week or more had memory scores similar to people with more education," said Lachman. The study, called Midlife in the United States, assessed 3,343 men and women between the ages of 32 and 84 with an average age of 56 years. Almost 40 percent of the participants had at least a 4-year college degree. The researchers evaluated how the participants performed in two cognitive areas, verbal memory and executive function --- brain processes involved in planning, abstract thinking and cognitive flexibility. Participants were given a series of tests, including tests of verbal fluency, word recall, and backward counting. As expected, those with... Question: What is the text mainly about? - Higher education has a better cognitive advantage. - Better memories result from college degree. - Cognitive activity does good to one's mind. - Poor education has more risk of memory declines.
Cognitive activity does good to one's mind.

Read the following article and select the best answer. 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. Question: What can be inferred from the passage about the gray-haired day? - She has been living with her father. - She was sad about the death of her father. - She can't search for her father without being watched. - She suffers from Alzheimer's disease.
