Putting in water fountains(��ˮ��) at schools, and teaching children about the health benefits of water, could reduce their risk of getting extra pounds, reports a new study that is published in the latest issue of the journal pediatrics.
The findings are based on a survey in 32 elementary schools of two German cities, Dortmund and Essen. The researchers, led by Rebecca Muckelbauer, a nutrionist at the Research Institute of Child Nutrition Dortmund, weighed about 3,000 children, and asked them about their beverage(����) consumption.
At the beginning of the school year, the experts had water fountains added to 17 of the schools. The scientists also worked with teachers to carry out educational programs that promote the benefits of drinking water. In contrast to schools in the United States, there are very few schools in Germany that have water fountains.
At the beginning of the study, there were no big differences in the number of overweight children in different groups. But by the end of the school year, children in the schools with water fountains were 31 percent less likely to gain extra pounds, compared to kids who went to other schools, where water drinking was not encouraged.[��Դ:ѧ
Children in the schools with fountains, increased their water consumption from about 3 up to 4 glasses a day, while those in the other schools continued to drink an average of 3 glasses. Over the research, the number of overweight kids upped from 384 to 385 out of 1,641 at the schools with water fountains. In comparison, the number of overweight kids at the other schools increased from 339 to 364 out of 1,309, Dr. Muckelbauer said.
The experts cannot make any final conclusions and explain why the students who were encouraged to drink water were less likely to gain extra weight. Dr. Muckelbauer noted that according to a few other studies, drinking of water increases the rate at which calories are burned, while some other research suggested that water may temporarily decrease appetite.

Should students do the grading?
The Supreme Court says the practice doesn’t violate(侵犯) 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(暴露) 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 reinforce 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 to a group of peers(同龄人). This can be very embarrassing. Releasing this sort of personal information should be avoided, especially by institutions that seek to provide a supportive environment during essential years of human development.

3.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
4.What does Winston Smith seem to agree?
A. Student grading is not related to families’ privacy.
B. The Supreme Court should change its decision.
C. The Buckley Amendment doesn’t apply to student grading.
D. Student grading is OK, but not public announcement of grades.
Little did I know that I was about to see something I would never forget at the Kentucky Association of School Administrators.
They introduced the young musician---Mr Patrick Henry Hughes. He was rolled onto the stage in his wheelchair and began to play the piano. His fingers danced across the keys as he made beautiful music.
About ten minutes into Patrick’s performance, someone came on the stage and said, “I’d like to share a seven-minute video about Patrick Hughes.” Then the lights were turned down.
Patrick Henry Hughes was born with no eyes and a tightening of the joints(关节), which left him disabled for life. However, he was fitted with artificial eyes and placed in a wheelchair. Before his first birthday, he discovered the piano. His mom said, “I could hit any note on the piano, and within one or two tries, he’d get it.” By his second birthday, he was playing records people asked for. His father was ecstatic. “We might not play baseball, but we can play music together.”
Today, Patrick is a junior. His father attends classes with him and he’s made nearly all A’s. He’s also a part of a 214-member marching band(游乐乐队). He’s a blind, wheelchair-bound trumpet player; he and his father do it together. In order to attend Patrick’s classes and every band practice, his father works the night shift(夜班) at United Parcel Service. Patrick says, “My dad’s my hero.”
On stage, between songs, Patrick talked to the audience about his life and about how blessed he was, “God made me blind and unable to walk. BIG DEAL! He gave me musical gifts and the great opportunity to meet new people.”
When his performance was over, the crowd rose to their feet and cheered for over five minutes.

Solitude can be hard to discover ______it has been given up. In this respect, new technologies have ______our culture.
The desire to be connected has brought solitude to a(n) as we've known it. People have become so in the world of networks and connections that one can often be contacted they'd rather not be. Today we can talk, text, e-mail, chat and blog (写博客), not only from our , but from our mobile phones as well.
Most developed nations have become on digital technology simply because they've grown accustomed to it, and at this point not it would make them an outsider. , many jobs and careers require people to be .
