Taking a math test can be pretty stressful. Even if you know the material, you can still get the problem wrong. {#blank#}1{#/blank#} Therefore you'll improve your grades, as well as your math skills.

    Write it out

    You can also check a math problem by writing everything out on paper. {#blank#}2{#/blank#} Writing out math problems reduces your chances of missing anything to the lowest possible level, which is a common cause of incorrect answers.

    {#blank#}3{#/blank#}

    Make sure your answers work by doing the opposite procedure of what your problem calls for, including the answer you got the first time around. In other words, you would use the opposite of this addition problem—subtraction (减法)—to determine whether your answer is the correct one.

    Plug in（代入）

    You may find that a variable isn't good enough or have a problem where you have to solve for a variable (变量). {#blank#}4{#/blank#} This is the only real way to assure yourself that the answer you've found is correct.

    {#blank#}5{#/blank#}

    If the result of a problem seems to make no sense, it indicates that the answer is incorrect. For example, if you get an answer in the millions and you know it should be in the thousands, you've likely misplaced a point. Go back through the work on your paper to make sure all of your formulas and calculations are correct. If everything looks okay, do the problem again and compare the result of the second try to what you've got on the first try.

A. Do the opposite.

B. Correct the answers.

C. Plug the variable in the equation (方程) to check it out.

D. Knowing how to go through your math test and checking your work can save you from handing in a test full of mistakes.

E. It also helps you to figure out everything after you have already finished the test.

F. Check for a reasonable answer

G. This helps you to know what information you have and what information you need to solve.

    Winters are long and unforgiving in North Dakota. The winter of 1996 was especially brutal. It was a hard time in my own life too. A neck injury had kept me flat in bed for nearly a year. “Just in time for Easter,”my husband, Dick, said. But how could I feel the joy when the snow was four feet deep and I had months of painful physical treatment ahead?

    I was doing the dishes one day, feeling hopeless when there was a tap against the glass. It was a branch of the troublesome cottonwood (棉白杨).Back in the fall of 1979, it was a new subdivision (分支）then, an eight-foot stick. The people who'd briefly occupied the house before us had placed the pipe from the pump next to it. The earth was so wet that the poor thing had fallen down, most of its bare root system pointing skyward, and blowing hopelessly back and forth in the cold wind. Dick decided to pull it out one day, but I protested.

    “Look at how hard it's trying!” I said, pointing to the way it strongly kept hold of the earth. “It deserves a chance.”

     Dick borrowed some tools. We packed dry soil around the tree and put up some stakes (桩) into the ground, making it stand upright. That winter was still terrible. Surprisingly,in the spring my “rescue stick”put forth a few leaves,then with lots of branches. The year after that, we were able to remove the stakes. By the 1990s that little stick was a giant, towering over the house.

    Now the tapping at the window continued, louder as the wind picked up, almost as though to tell me to look up. At last, I did. I caught my breath. In the window against the icy blue sky, thousands and thousands of fresh red buds were waving in the wind.

    The tree was bursting with life and I had a wonderful Easter.

    While there are many fascinating countries in the world to visit, I think there is something more adventurous, exotic (异国风情的) and romantic about visiting an island country. Take a look at some breathtakingly beautiful island countries in the world, which everyone should certainly visit at least once in his lifetime.

    Malta

    Malta is a beautiful southern European country in the Mediterranean Sea, which has a rich history and culture. There are amazing sky-high cliffs to climb, splendid temples to explore and lots of wonderful places to go scuba-diving. In fact, there are plenty of interesting things to see and to do in Malta and this island country has something for everyone. The historic part of Malta is shown in its incredible architecture, great walled cities, and many underground tunnels.

    Fiji

    Fiji is a fabulous island that has plenty of surprises for any adventurous travelers. It is famous for the world's best surf scenes, and many surfing enthusiasts travel to Fiji yearly to ride the great wives. Well, if surfing is not for you and you love sitting on the beach and relaxing, hiking or seeing breathtaking waterfalls, Fiji is certainly the best island country to visit.

    Maldives

    Not only is Maldives one of the most beautiful island countries, but it is one of the most popular honeymoon destinations. Situated in the middle of the Indian Ocean, Maldives is made up of a series of ancient coral reefs that grow up along the sides of ancient volcanoes, with fascinating beaches and luxurious resorts.

    If anyone knows what makes a great children's book,it must be Sussex author and illustrator(插图家) Jane Hissey. Her " Old Bear" books have achieved classic status in a variety of formats.

    I caught up with Jane at her home in the East Sussex countryside and asked her what she thinks is the secret of a classic children's book. "That's a difficult one. I suppose it's got to be relevant to the child's stage of development-for young children, pictures on a page that are familiar, for older children, an experience. The book should be familiar,but hold some surprises too to keep the interest. It must inspire and delight, but there are the things that happen every day. "

    After the birth of her first child,she gave up teaching and worked on her own artwork, drawing pictures of teddy bears. An editor from a publishing company saw her work and invited Jane to do a children's book. Over the years, from the first " Old Bear" book in 1988,her children have made a huge contribution-not least in terms of plot. She said, "I used to give my children the toys to play with-and they had tea parties and so on. One of my bear characters,"Little Bear",is the same age as Ralph, my youngest, who's seven now. All the children have joined in my work and,in years to come, they will realize how much. "

    "I hope I'll know when people are getting tired of the characters. If ever they did, I think I'd go on drawing them for fun," Jane continued," My own children have been very useful to me in my work, but as they are older now, I'll just have to hope that other people's children can inspire me. "

    After two years of careful consideration, Robert McCrum has reached a conclusion on his selection of the 100 greatest novels written in English. Take a look at a few in his list.

    The Pilgrim's Progress by John Bunyan (1678)

    A story of a man in search of truth told with the simple clarity and beauty of Bunyan's prose makes this an English classic.

    Robinson Crusoe by Daniel Defoe (1719)

    By the end of the 19th century, no book in English literary history had enjoyed more editions and translations. This world-famous novel is a complex literature that one cannot resist.

    Gulliver s Travels by Jonathan Swift (1726)

    A great work that s been repeatedly printed, Jonathan Swift's Gulliver's Travels comes third in our list of the best novels written in English.

    Clarissa by Samuel Richardson (1748)

    Clarissa is a tragic heroine, pressured by her dishonorable family to marry a wealthy man she dislikes, in the book that Samuel Johnson described as “the first book in the world that shows the knowledge about the human heart”.

Tom Jones by Henry Fielding (1749)

    Tom Jones is a classic English novel that gets the spirit of its age and whose characters are well-known since they have come to represent the society at that time.

    Emma by Jane Austen (1816)

    Jane Austen's Emma is her most outstanding work, mixing the best parts of her early books with a deep sense of feelings.

    The Narrative of Arthur Gordon Pym of Nantucket by Edgar Allan Poe (1838)

    Edgar Allan Poe's only novel－a classic adventure story with supernatural elements－has fascinated and influenced generations of writers.

    Nezha is the subject of the latest feature, which officially opens in cinemas in China on Friday. Nezha has earned hot reviews and is ranked higher than Monkey King: Hero is Back. It is also China's first 3D animated feature film released in IMAX format.

    Since July 13, previews of the film have taken more than 140 million yuan at the box office and the film has a score of 8.8 points (out of 10) on China's largest filming rating site, Douban. It took Jokalate Yang Yu, the film's director and screenwriter, two years to improve the script (剧本) of Nezha, and the film was in production for three years. It is the most complex animated production ever made in China. Nezha has more than 1,300 special effects shots, and it took over 20 Chinese special-effects studios, employing more than 1,600 people, to realize the film's fairy tale setting, the mysterious Dragon King's palace and a fight between fire and water. One splendid scene alone took two months to complete.

    Yang made up his mind to produce an animated film on the theme of breaking the traditional styles and changing fate to the opposite. Yang chose Nezha as his vehicle, the representative of the rebellious (叛逆的) but righteous youth. However, compared with the original novel and past animated versions, the relationships between the characters are given modern meaning. In Yang's film he is fighting prejudice: Nezha is hated and feared. But Nezha believes his fate is not predetermined and that he can choose to be a devil (恶魔) or a god.

    "After watching so many domestic animated films, only Nezha and Monkey King: Hero is Back have made me fascinated," a Weibo user commented under the promotional video.

    "Epic! I finished watching Nezha in tears. The content-rich story, vivid characters, and amazing visual effects, work together to create a 110-minute roller-coaster (过山车) watching experience," a Douban user commented.

    "Bravo! Couldn't believe a domestic animated film can be created with such a well-developed story. The image of Nezha in this film has been overturned but his rebellious spirit is well-established. I'm sure Nezha is gonna go viral this summer!" reads another comment on Douban.
