Teachers say the digital age has had a good influence and a not-so-good influence on this generation of American teenagers. More than 2,000 high school teachers took an online survey.

    75 percent of the teachers said the Internet and digital search tools have had a “mostly positive” effect on  their students' research habits and skills. But 87 percent agreed that these technologies "make the students not have enough attention.” And 64 percent said the technologies “do more to distract students than to help them academically.”Many students think “doing research” now means just doing a quick search on Google.

    Judy Buchanan is a director of the National Writing Project. Ms. Buchanan says digital research tools are helping students learn more, and learn faster. Teachers really like these tools, because they are ways to make some of learning exciting. Young people enjoy using these tools. And the goal is to help them become creative students of meaningful work, and not just that kind of copyist.

    But one problem the survey found is that many students don't have a good understanding of how to use the digital knowledge well. In other words, they trust(信任) too much of the information. Judy Buchanan says these students have not developed the skills they need to tell whether the online information is good or bad.

    Another problem the survey found is something that might not seem like a problem, at all, being able to quickly find information online. Teachers say the ability of their students to work hard to find answers is becoming weaker. They say students depend too much on search engines (引擎) and do not make enough use of printed books or research, librarians.

    Besides, many teachers are also worried about the problem that the Internet makes it easy for students to copy work done by others, instead of using their own abilities.

    Every country has its heroes .They may be soldiers or sports people, doctors or film stars. We admire（钦佩） them for their courage, their strength, their devotion（忠诚） to duty or their talent. Their example inspires us to live better, to work harder.

    Terry Fox was a young student who loved life and who loved sports. When he was just 18 years old a terrible tragedy happened: his right leg had to be cut off because of cancer. Such an experience would have destroyed a weaker person — but Terry Fox was a fighter. He refused to give up. Instead, while he was recovering from the operation, an idea slowly formed in his mind. He decided he would run across Canada, in order to raise money for cancer research.

    Slowly and carefully, he began to train. Every step was extremely painful, but he insisted, increasing the distance covered day by day. Sixteen months later, in the spring of 1980, he was ready for the long journey across Canada — his Marathon of Hope .It was a time of inspiration and heart breaking emotion. Through television, every home saw his particular way of running, a kind of half- hop and half- run. Thousands of people lined the route to encourage him and to wish him well. They also gave money to fight cancer. Then, on 1st September 1980, after 143 days and more than 5000 kilometers completed, everything came tragically to an end Terry had to stop. He lived on for another nine months and died on June 18th 1981. He was almost 23.

    The recommended dose (剂量) ranges from two to three tablets at a time. Never take more than 4g 12 tablets) in any 24 -hour period.

    You must not take these tablets with any other medicine which contains any aspirin or painkiller.

    How to store aspirin:

    Keep all medicines out of the reach and sight of children.

    A new study suggests a simple getting-to-know-you exercise might improve classroom relationships. The teacher-student relationship affects every aspect of the educational experience. When students don't feel safe and respected by their teacher, they are less likely to devote themselves to their education. And when teacher feel distanced from their students, it is nearly impossible to walk into the classroom each day actively, let alone encourage motivation or investment in students.

    Hunter Gehlbach, a professor, explained that his research is primarily concerned with social perspectivetaking(换位思考), or the ability to understand what drives the people around us. As he explained, "My focus is classrooms and social perspective-taking--figuring out the thoughts and feelings of others seems important. We want teachers to be able to engage in this process and figure out the thought process of students as much as possible, in order to understand where and why they are making mistakes."

    Gehlbach and his colleagues gave 315 students and 25 teachers a "getting-to-know-you" survey of 30 items at the beginning of a school year. The researchers matched similarities between the teacher and the student, and then showed those similarities to the teachers and students. Five weeks later, the researchers returned to start a more indepth survey of both students and teachers, and to measure their opinions of their relationships and the classroom experience as a whole. The second survey showed that when teachers and students know they have five things in common, relationships and educational outcomes both improve.

    Gehlbach explained that the similarities he and his colleagues established were not based on personal information, but on shared preferences. Gehlbach explained: one of the biggest surprises in reading the similarity research was how little some of the similarities were that caused positive feelings towards others.

    Though Gehlbach's study has limitations, he is encouraged by the results and eager to explore the phenomenon further.

    A large body of research has been developed in recent years to explain many aspects of willpower. Most of the researchers exploring self-control do so with an obvious goal in mind: How can willpower be strengthened? If willpower is truly a limited resource, as the research suggests, what can be done to make it stay strong?

    Avoiding temptation (诱惑) is an effective method for maintaining self-control, which is called the "out of sight, out of mind" principle. One recent study, for instance, found office workers less attracted to candy in the desk drawer than that on top of their desks, in plain sight.

    The research suggesting that we possess a limited reservoir of self-control raises a troubling question. When we face too many temptations, are we to fail? Not necessarily. Researchers don't believe that one's willpower is ever completely exhausted. Rather, people appear to hold some willpower in reserve, saved for future demands. The right motivation allows us to tap into those reserves, allowing us to carry on even when our self-control strength has been run down. High motivation might help overcome weakened willpower-at least to a point.

    Willpower may also be made less vulnerable (脆弱) to being exhausted in the first place. Researchers who study self-control often describe it as being like a muscle that gets tired with heavy use. But there is another aspect to the muscle comparison, they say. While muscles become exhausted by exercise in the short term, they are strengthened by regular exercise in the long term. Similarly, regular practices of self-control may improve willpower strength.

    The evidence from willpower-exhaustion studies also suggests that making a list of resolutions on New Year's Eve is the worst possible approach. Being exhausted in one area can reduce willpower in other areas, so it makes more sense to focus on a single goal at a time. In other words, don't try to quit smoking, adopt a healthy diet and start a new exercise plan at the same time. Taking goals one by one is a better approach. Once a good habit is in place, Baumeister says, you'll no longer need to draw on your willpower to maintain the behavior. Eventually healthy habits will become routine, and won't require making decisions at all.
