Here are six steps to better studying.

Pay attention in class

    Do you have trouble paying attention in class? Are you sitting next to a loud person? Tell your teacher or parents about any problem that is preventing you from paying attention.

Take good notes

    Write down facts that your teacher mentions or writes on the board. Try to use good handwriting so you can read your notes later. It's a good idea to keep your notes organized by subject.

Plan ahead for tests and projects

    Waiting until Thursday night to study for Friday's test will make it hard to do your best. One of the best ways to make sure that doesn't happen is to plan ahead. Write down your test dates. You can then plan how much to do after school each day, and how much time to spend on each topic.

Break it up

    When there's a lot to study, it can help to break things into several parts. Let's say you have a spelling test on 20 words. Instead of thinking about all of the words at once, try breaking them down into five-word groups and work on one or two different groups each night.

Ask for help

    You can't study effectively if you don't understand the material. Be sure to ask your teacher for help. If you're at home when the confusion occurs, your mom or dad might be able to help.

Sleep tight

    So the test is tomorrow and you've followed your study plan—but suddenly you can't remember anything! Don't panic. Your brain needs time to digest all the information you've given it. Try to get a good night's sleep and you'll be surprised by what comes back to you in the morning.

    One May morning, 10-year-old Khadab played in the ruins of a school near his home in northern Iraq. He saw something that looked interesting. It was yellow and plastic and looked like a ball. He reached for his new toy and, BANG!

    The last thing he remembered was a big noise. When Khadab awoke, he was in hospital. His parents stood sadly by his side. They told him he had picked up an unexploded bomb. When it exploded, Khadab lost an arm.

    He was just one of hundreds of Iraqi children who have been injured or killed by stepping on and picking up explosives left over from the war.

    These landmines (地雷) and bombs have injured and killed at least 15 people a day since Saddam Hussein's government fell on April 9. And children are the most affected.

    Iraq is among the worst landmine-affected countries in the world. Many villages in the war-torn areas are surrounded by minefields (雷区). These landmines lie on the ground between rocks, up in trees and on riverbeds.

    Even though the war in Iraq is over, many children have not returned to school. They can be seen walking the streets with the natural curiosity of young kids. Their new playgrounds are places where the fighting took place. Many boys can be seen playing with unexploded bombs. A new game is to throw the bombs and run away. Some of them get away, but too many are killed. They do this for fun, and don't realize the dangers until it's too late.

    UNICEF (联合国教科文组织) has warned children, through the TV, of the dangers of landmines and unexploded bombs in Iraq. They hope to make children aware of the dangers they face.

    “I can't imagine there's going to be a classroom in the north without scared children in it. It's so widespread,” said Sean Sutton of the British-based Mines Advisory Group (MAG).

    MAG is an organization working to clear unexploded bombs and landmines in war-torn areas.

    It is difficult to report the exact number of deaths. Sutton said MAG found 320 injuries in northern Iraq in the first month after April 9. But he said the real figure was probably much higher.

    The human body is designed to move. But modern lifestyles and office jobs rarely give us the chance to move around. As we know, we're sitting while we're eating; we sit in the car and we sit while we watch TV. And many of us sit for many hours at work.

    New research shows that sitting less than three hours a day might extend your life by two years. Peter Katzmarzyk, a scientist at the University of Louisiana in the southern United States, says that sitting is ubiquitous in our lives, meaning it is something we do all the time, everywhere.

    However, Mr. Katzmarzyk says that does not mean you can sit for the rest of your waking hours. He also says you may exercise often, "We can't throw away physical activity. It's extremely important. We have 60 years of research showing us that."

    Mr. Katzmarzyk and his colleagues are part of a new generation of researchers studying how sitting all day affects length of life. "Studies that have assessed the relationship between sitting and mortality (死亡率) or television viewing and mortality are very rare. There's only been a few of them, actually five or six now, in the last four or five years." They found that cutting television time to less than two hours a day could add one point four years to life.

    Luckily, change is already coming to some offices, especially in the design of desks. A "standing desk" lets people stand while they work. Another new design is called the "treadmill desk." A treadmill is an exercise machine that lets you walk in one place. Even some U.S. schools are beginning to experiment with desks that are part bicycle to keep children moving. That's one of the strategies that many companies are using now.

    Mr. Katzmarzyk also says studying this problem has inspired his team to make a few changes in their own lives.

    I grew to be a tall girl but I tried to be as ordinary as possible. At school, I always chose a seat in the back of the room, and never raised my hand in class. When I was 16, I went to my new school. And I liked the English teacher. In my last year in high school, however, we were told that a new English teacher, Oliver Bascom, was going to teach us.

    Oliver Bascom! The girls laughed as we imagined a short and bald（秃头的）man．The situation was not funny, because this man would teach us for the whole year. Surprisingly, after we opened the door, there in front of the blackboard, we saw a young and handsome man!

    What followed was chaos, seventeen-year-old girls flying to get to seats in the front of the room. And I managed to get a front and center desk.

    I really wanted to make a good impression on my new teacher, but I usually kept quiet. The day that directions were given for our first major writing assignment, I arrived late to class. A friend later gave me the guidelines and I thought I understood them. I worked the whole weekend on the essay and waited nervously for Mr. Bascom's evaluation.

After three days, he arrived in class holding the corrected papers. "I've chosen the ten best essays for class discussion." he said.

    Twenty minutes later, my heart sank when he got to the last essay, and I didn't hear my name.

"These are all great essays," Mr. Bascom continued. "However, I am now going to read you the most successful of all…" We were all surprised as I was the author of this unusual work. A different girl walked out of the classroom that day. I knew that I had a new set of standards to live up to and that anything was possible in the future. Finally, I raised my head.

    Many of us have reached in our pockets, feeling a vibration (振动), wrongly believing our mobile phones have just rung. The phenomenon even has a name: phantom (幻觉的) vibration syndrome—and found it is surprisingly common.

    Now scientists believe that we are so alert (警觉) for phone calls and messages we are misinterpreting slight muscle spasms (痉挛)as proof of a call. Robert Rosenberger, an assistant professor at the Georgia Tech Institute of Technology has studied the delusional calls. He said sufferers describe a vague tingling feeling which they think is their mobile phone indicating it has received a text message or call while on 'silent'. But when the device is retrieved, there was no one on the other end.

    Dr. Rosenberger said he found so many people say, "This happens to me, but I thought I was the only one. I thought I was odd." It seems that the syndrome particularly affects people at the beck and call of mobile phones or pagers. A 2010 study by Michael Rothberg and colleagues found that nearly 70 per cent of doctors at a hospital in Massachusetts suffered phantom vibrations. A more recent study of US college students found the figure was as high as 90 per cent.

    While the odd feeling is widespread, it does not seem to be considered a grave problem. Dr. Rosenberger said: "It's not actually a syndrome in a technical sense. That's just the name that's got stuck to it." He added," Only 2 per cent of people consider it a problem."

    While this phenomenon is widespread, the scientific community has not yet invested much effort in getting to the bottom of why we suffer phantom calls.

    Dr. Rosenberger said: "People are guessing it has something to do with nervous energy. The cognitive(认知的)scientists are talking about brain chemistry, cognitive pathways changing. But it's not like they have brain scans to go on." He said: "We have a phone call in our pocket all the time and it becomes sort of an extension of ourselves. We have this sort of readiness to experience a call. We feel something and we think, OK, that could be a call."

    Fourth-grader Alice Tapper was on a school field trip when she noticed that most of the girls quietly stayed at the back of the group, while the boys gathered at the front and raised their hands to answer questions. The 11-year-old then realized how often she and her female classmates didn't speak up in class for fears of getting an answer wrong and being embarrassed.

    She decided to change this and launched a campaign to encourage girls to have faith in themselves, even take risks and be leaders —— and support other girls in doing the same. With assistance from her Girl Scout troop (女童子军), she created a new Raise Your Hand program, and soon girls around the country were taking a pledge(承诺) to raise their hands in class.

    In my work as an administration coach I see many women (and some men) with habits that are holding them back. Women at work tend to hang back in meetings for fear they may not have the right answer. They will spend countless hours (and sometimes days) replaying the tapes in their head, while males in similar situations simply move on, until they are perfect when instead they should be establishing relationships. The truth is that after a year no one remembers your nice report. Forget perfect. It doesn't exist. Say what's on your mind and let things go.

    Similarly, women tend to talk more softly than men, which can be problematic, especially the higher up in the organization you go. To have an influence on business, it's not enough to have a seat at the table. You have to have a voice and people have to hear from you. Don't wait for an invitation. Raise your hand, say what you have to say, and when you see an opportunity, go for it!
