Should students do the grading? The Supreme Court says the practice doesn't violate  a student's right to privacy, but is it right for students to grade one another? Walter Potenza, California The Supreme Court was absolutely correct to say it's OK for students to grade one another's homework, quizzes, and tests: in fact, it's a great idea. By grading one another's papers and seeing the problems their classmates have, students double their exposure  to the troubles that they may meet on future exams and tests. Grading one another's papers may be one of the best ways for students to _ within themselves the ways to master the most difficult parts of what they are learning. Teachers are underappreciated and underpaid for the number of hours they have to work to be able to teach really well. Grading all their students' papers can take hours. Some of that time and energy can be saved by spending a few minutes in class, while providing an extremely valuable learning experience. I understand that some individuals are sensitive to their classmates seeing their work or grades. Any good teacher would be considerate of students who don't want their classmates to grade their assignments. Winston Smith, North Carolina A girl moves back as her classmate announces her failing test grade and hands her the paper. The quiet classroom heats up. With the increase in student grading over the past few years, scenes like this have become a bitter reality in schools across the nation. Teachers and schools should not advocate student grading and public announcement of grades because it provides a violation of privacy for students and causes unfair judgments and treatment by their classmates. Since 1974, a law known as the Buckley Amendment has forbidden the release of education records in order to protect the privacy of students and their families. I strongly disagree with the Court's ruling that this law does not include student grading. I can think of no greater violation of privacy than the exposure of one's personal information... By mentioning the example of a girl, Winston Smith wants to   _  . A) show her weak points B) criticize the student grader C) tell us she is not a good student D) present the negative effect of student grading

The small number of newborn babies, which has been caused by high prices and the changing social situation of women, is one of the most serious problems in Asia. When people talk about it, you can hear a word invented in Japan. which means Double Income Kids . In many major Asian cities like Seoul, Singapore, and Tokyo, the cost of a ****** is extremely high. A young couple who want to buy their own house may have to pay about $3000,000 (though prices have fallen). For a flat with one bedrooms, one dining-room, a kitchen, and a bathroom, the couple will pay about $900 a month. What's more, if they want to have a child, the child's education is very expensive. For example, most kindergarten charges are at least $5.000 a year. In such a situation, it's difficult to afford children. The number of married women who want to continue working because they enjoy their jobs. However, if they want to have children, they immediately have serious problems. Though most companies allow women to leave their jobs for a short time to have a baby, they expect women with babies to give up their jobs. In short, if they want to bring up children properly, both parents have to work, but it is hard for mothers to work. Indeed, women who want to contimue working have to choose between having children or keeping their jobs. In a word, Asian governments must take steps to improve the present situation as soon as possible. According to the passage, which of the following is true? A) It is easy for a couple to afford a child in Asia. B) The prices of in Asia are quite low now. C) Fewer and fewer married women wan to have a job. D) The word "DINKS" appeared in an Asian country.

To all of you at Chinese love links, I am 44 years old and never married. I have always wanted to find that perfect someone that I dream about. For about the last five years I have almost given up the hope of ever finding the one I truly wish to spend the rest of my life with. I have always tried to be a nice guy. I had found your website some four or five months before. I did not know what to expect. I don't know how to speak Chinese and never thought truly of how I was to an Asian woman. Well, I had a lot of replies from some very nice and pretty women. I had a hard time finding only a couple to write to. But one stood out from the rest. She was cute, nice and seemed to hold a lot of the same values as I do. In a short time I had decided to write only to her. We communicated via e - mails 2 - 3 times a day and phone calls once or twice a week.  I went and met her and her family only a week ago. Her name is Ying and she lives in prefix = st1 /Nanning. I foundNanningto be one of the most beautiful cities I had ever been to. We had even decided to marry and to bring her to theUSAunder the fiancee visa. Not only did she meet everything I had ever hoped to find in someone else but turned out to be what every woman should be like, at least the ones I have met. We plan to marry as soon as she is here and start a family together as neither of us has children but we both want them. So to anyone out there reading this, I can only say this: You may not find what you are looking for if you're not honest with your partner and yourself. This site worked for me mostly because I was honest with something that I wanted in someone else. When I did find her, love can work even across the other side of the world, between language differences and cultural differences. I wish you all luck in finding your perfect match. I have finally found mine and wishto give all my thanks to those at Chinese love links to help make it happen. Sincerely yours, Arthur Arthur thinks  _  is the most important in finding someone one wants to marry. A) being honest with the partner and oneself B) help from the website C) difference in languages and places D) difference in cultures

Every electronic gadget   needs good memory. A music player stores songs, albums and playlists. A computer holds schoolwork and programs and remembers how far a player has advanced in his or her favorite game. Mobile phones store names, numbers and hundreds of texts. Now, scientists in California say they have come up with a way to turn a living cell into a memory device. It can store only one tiny bit of information, but it's a start. In the future, a cell-based gadget might travel through the body and record measurements. The benefit to human health could be big: the right tool, for example, might record the earliest signs of disease. Doctors, scientists and other curious people want to know what is happening inside the body, even at levels that can't be seen by the naked eye. So far, there is no device small enough to travel through the bloodstream. If normal machines won't do the trick, perhaps biology will. Scientists who work in the field of synthetic   biology are trying to find ways to turn living things into human tools. In the case of the new memory device, bioengineers from Stanford University used the genetic material inside living cells to record information. This genetic material consists of DNA. Found in nearly every cell, DNA carries all of the information that keeps a living thing alive. In the new experiment, the researchers turned DNA from bacteria  into a switch. They "flip  " a small section of DNA. Then, using the same procedure   , the scientists flip the section again--returning it into its normal structure. Using these DNA switches, "We can write and erase DNA in a living cell," bioengineer, Jerome Bonnet, explained to Science News. It might take years before his team or others identity whether a DNA-based memory device might be practical. Right now, it takes one hour to complete a flip. That is far too long to be useful. Plus, a flipped section has a very small little memory--less than what a computer uses to remember a single letter. "This was an important proof that it was doable,"... What is possible future benefit of the cell-based gadget for people? A) To detect disease at the earliest point. B) To help improve the memory. C) To help people build a body. D) To replace many electronic gadgets.
