Most book reviews start with a headingthat includes all the basic information about the book, like:

Title.

Author.

Place of publication, publisher, date ofpublication.

Number of pages.

    Like most pieces of writing, the review usually begins with an introduction that lets your readers know what the review will say. The first paragraph usually includes the author and title again, so your readers don't have to look up to find this information. You should also include a very brief description of the contents of the book, the purpose or audience for the book, and your reaction and evaluation.

Then you move into a section of background information that helps place the book in context and discuss escriteria (准则）for judging the book. Next, the review gives a summary of the main points of the book, quoting and explaining key phrases from the author. Finally, you get tothe heart of your review – your evaluation of the book. In this section, you might discuss some of the following issues:

how well the book has achieved its goal

what possibilities are suggested by the book

what the book has left out

how the book compares with others on the subject

what specific points are not convincing

what personal experiences you've hadrelated to the subject.

    It is important to use labels to carefully distinguish your views from the author's, so that you don't confuse your reader.

    Then, like other essays, you can endwith a direct comment on the book, and tie together issues raised in the reviewin a conclusion.

    There is, of course, no set form, but ageneral rule is that the first one–half to two–thirds of the review should summarize the author's main ideas and at least one–third should evaluate thebook.

    Here, sleep experts clear up some of the biggest misunderstandings about sleep they see with their patients, which could weaken your ability to have a night of good sleep.

Myth: {#blank#}1{#/blank#}

    The latest research shows that the right amount of sleep may vary from person to person and should leave you feeling energized the next day. I'm a sleep doctor. Take myself for example. {#blank#}2{#/blank#}.

Myth: Don't fall asleep with the TV on.

    I've cured more people suffering from sleep problems than you can imagine by telling  people it's OK to fall asleep with the TV on. {#blank#}3{#/blank#}Control the watching time so it doesn't affect your sleep later in the night.

Myth: You can catch up on lost sleep on the weekend.

    {#blank#}4{#/blank#} A Harvard study found that even if you sleep for an extra 10 hours on the weekend to make up for only sleeping six hours a night for two weeks, those extra hours won't improve  your reaction times or ability to focus. Plus, sleeping late throws off your biological clock, which can lead to obesity, diabetes, and heart disease.

Myth: Alcohol can help you rest easy.

    {#blank#}5{#/blank#} Alcohol may relax you so you nod off quicker, but studies show you'll wake up more and get less of deep sleep you need to feel rested.

    A couple of days ago, as the test results came out, my son and a group of his 13-year-old friends piled into the back seat of my car, ready for the last-day-of-school party at McDonald's. “Jack got a laptop for getting straight A's, and Laurie got a cell-phone,” one boy said. “Oh, yeah, and Sarah got an iPad, and she's only in third grade,” said another. “And how about Brian? He got $10 for each A.”

    I suddenly became concerned. These payoffs might get parents through grammar school, but what about high school and beyond? What would be left after the electric guitar, the cell-phone, and the DVD player?

    I saw the road ahead:As the homework load increased, my income would decrease.I saw my comfortable lifestyle disappear before my eyes — no more of those $5 bags of already-peeled organic carrots. No more organic anything!

    I started to feel surprised and nervous. Would every goal achieved by my two children fetch a reward? A high grade point average? A good class ranking? Would sports achievements be included in this reward system: soccer goals, touchdowns? What about the orchestra? Would first chair pay more than second? I'd be penniless by eighth-grade graduation.

    “We never paid anything for good grades,” said my neighbor across the street, whose son was recently accepted at MIT. “He just did it on his own. Maybe once in a while we went out for pizza, but that's about it.”

    Don't you just hate that? We're all running around looking for the MP3 player with the most updates, and she's spending a few dollars on pizza. She gets motivation; we get negotiation. And what about the primary grades? What do these students get? “When the teacher asked if anyone got rewards for good grades, everyone in my class raised their hands and said they got ice cream cones ,” said one third-grader.

    I was sure that I was to be killed. I became terribly nervous. I fumbled(摸索) in my pockets to see if there were any cigarettes, which had escaped their search. I found one and because of my shaking hands, I could barely get it to my lips. But I had no matches, they had taken those. I looked through the bars at the guard. He did not make eye contact with me. I called out to him “Have you got a light?” He looked at me, shrugged and came over to light my cigarette. As he came close and lit the match, his eyes unconsciously locked with mine. At that moment, I smiled. I don't know why I did that. Perhaps it was nervousness, perhaps it was because, when you get very close, one to another, it is very hard not to smile. In any case, I smiled. In that instant, it was as though a spark jumped across the gap between our two hearts, our two human souls. I know he didn't want to, but my smile leaped through the bars and caused a smile on his lips, too. He lit my cigarette but stayed near, looking at me directly in the eyes and continuing to smile.

    I kept smiling at him, now thinking of him as a person and not just a guard. "Do you have kids?" he asked. “Yes, here, here.” I took out my wallet and nervously fumbled for the pictures of my family. He, too, took out the pictures of his family and began to talk about his plans and hopes for them. My eyes filled with tears. I said that I feared that I'd never see my family again, never have the chance to see them grow up. Tears came to his eyes, too. Suddenly, without another word, he unlocked my cell and silently led me out. Out of the prison, quietly and by back routes, out of the town. There, at the edge of town, he released me. And without another word, he turned back toward the town.

    A schoolgirl saved her father's life by kicking him in the chest after he suffered a serious allergic (过敏的) reaction which stopped his heart.

Izzy, nine, restarted father Colm's heart by stamping (踩) on his chest after he fell down at home and stopped breathing.

    Izzy's mother, Debbie, immediately called 999 but Izzy knew doctors would never arrive in time to save her father, so decided to use CPR.

However, she quickly discovered her arms weren't strong enough, so she stamped on her father's chest instead.

    Debbie then took over with some more conventional chest compressions (按压) until the ambulance arrived.

    Izzy, who has been given a bravery award by her school, said: "I just kicked him really hard. My mum taught me CPR but I knew I wasn't strong enough to use hands. I was quite scared. The doctor said I might as well be a doctor or a nurse. My mum said that Dad was going to hospital with a big footprint on his

"She's a little star," said Debbie, "i was really upset but Izzy just took over. I just can't believe what she did. I really think all children should be taught first aid. Izzy did CPR then the doctor turned up. Colm had to have more treatment on the way to the hospital and we've got to see an expert."

    Truck driver Colm, 35, suffered a mystery allergic reaction on Saturday and was taken to hospital, but was sent home only for it to happen again the next day. The second attack was so serious that his airway swelled, preventing him from breathing, his blood pressure dropped suddenly, and his heart stopped for a moment.

    He has now made a full recovery from his suffering.

    When he was 22, Rob Stewart traveled the world for four years. He wanted to call attention to the mistreatment of sharks. His 2007 film, Sharkwater, documents the cruel practice of removing sharks' fins (鳍) for money and leaving the animals to die. In his latest documentary, Revolution, Stewart takes on an even bigger challenge: climate change.

    The Canadian filmmaker says that climate change has harmed people and places everywhere: "It is stronger than any government or organization. If we educate people, they will make better decisions about protecting natural resources. "

    According to a recent report on climate change, "The atmosphere and ocean have warmed, the amounts of snow and ice have reduced, and sea levels have risen." These developments are endangering crops, wildlife, fish, and even people.

    Stewart says that the consequences of climate change will be irreversible unless people take action, especially young people."It's up to kids to be the moral compass (道德指南) of society," he believes, "and say, 'Guys, this is not right.'"

    Many kids took action after seeing Sharkwater. Elementary school students in the Northern Mariana Islands, for example, got their local government to ban the sale of shark fins.

    Felix Finkbeiner, 17, of Germany is also part of the "revolution" to save the planet. In 2007, Felix started a youth group called Plant-for-the-Planet, whose motto is "Stop Talking. Start Planting." The group raises money to plant trees. So far, Plant-for-the-Planet has planted nearly 200 trees around the world. "Future generations are the ones who will be suffering the most from inaction (无作 )," Felix says. His goal is to plant millions of additional trees.

    "When we started four years ago," Felix tells Stewart in Revolution, "we thought we had to save the polar bear. We thought we had to save the environment. But soon after, we found out that it's about our future, that we have to save our own future."
