Union is strength Whenever you're faced with difficulties or in a dilemma, cooperation plays an important part in getting you out of trouble.
There was a time when I was too proud that I overlooked my classmate, refusing to work together with them. Therefore, it was no doubt that I was left alone, suffering from loneliness and failure. Unfortunately a teacher impressed on me the value of cooperation. From then on, I learned to help others and turn to my friends for the help whenever I had difficulty finish a task on my own. Surely cooperation made a great difference. Now I am getting well with my friend.
My experience has teach me that only if we attach great importance with cooperation can we go beyond ourselves. As the saying go, "United we stand ;divided we fall."

Last Saturday, I went to visit the museum with my classmates. We were interesting in dinosaurs, but we came to the Dinosaur World first. There we see many fossils of different kind of dinosaurs. We were both amazed when the guide showed us some dinosaur eggs which they were laid about 9.5 million years ago.
Then we came to another hall, where many old Chinese inventions were in show. When I saw those old things, I felt proud of being Chinese. I think the visit very meaningfully. I should study harder to be inventor in the future and make contributions to build our great motherland.

Sometimes in February, my teacher told us about the city speech contest, its topic was “People who have overcome difficulties in their lives”. I thought of my grandma would be my perfect topic. Then I carefully prepared for contest. A couple of weeks later, after the first round I was choosing to be one of the seven finalists! The final was held soon. I was the sixth to present the speech. How a relief when I finished it ! After the last person finished, the judge made their final decisions and announced that I have won first prize. The audience were going wildly clapping and cheering ! I was extremely happy. It was such exciting a moment that I will always remember.
7. As is known by all，the Internet is playing a more and more important part on our daily life．On the Internet，we can not only read news at home or abroad but also get much information as possible．For an example，we often send e-mails and make telephone call to our families and friends．What’s more，they can go to school on the Internet，read different kinds of books and even teaches ourselves English．We can also listen to music，watching sports and play computer games．We can even do shopping without left our houses．
8.As the College Entrance Examination is drawing nearby, some students would rather expect good luck than to make every effort to study. They think success results good luck. Whether they can be admitted to key universities depend on luck. However, others insist that diligence is a mother of success. Only by working hard can they achieve what they want. Since they fail sometimes, they don’t give up, for they believe that success lies in our own hands. As for me, I’m in favor of the latter opinion. Luck doesn’t come alone. It goes hand by hand with hard working. Sometimes, some students are lucky enough to succeed, but such luck won’t last long because it is not basing on their own abilities.
9. This morning I was riding a bicycle on my way to school while suddenly a shower of heavy rain began to pour down. The wind is blowing hard and the road became very slippery. Just then I saw an elderly woman walking with difficult in the street. She was on her way back to home after shopping, carried a large basket full of vegetables. Suddenly she fell down in the mud. And she was very worn out that she couldn’t get up. Seeing this, I immediate rode over to her and tried my best to support her up. Then I
helped picking up the vegetables, and put them into her baskets. After that, I took off my raincoat, put on her and took her home.

Mr. Johnson is a hardworking teacher. Every day, he spends too much time with his work. With little sleep and hardly any break, so he works from morning till night. Hard work have made him very ill. “He has ruined his healthy. We are worried about him.” That is which other teachers say. Yesterday afternoon. I paid visit to Mr. Johnson. I was eager to see him, but outside her room I stopped. I had to calm myself down. Quietly I step into the room. I saw him lying in bed, looking at some of the picture we had taken together. I understood that he missed us just as many as we missed him.
11. I'm writing to tell you about a shocked incident that happened in Beijing Zoo in the afternoon of Feb 23rd.
I was visiting the zoo that afternoon while I heard bears roaring terribly. I hurried to the place where the bears lived at. I saw the black bear badly injured and one of them roll on the ground painfully. It was hurt too serious to move a foot. The people around was shocked, angry and blaming the wrongdoer. I learned that was a student from a famous university in Beijing who caused the trouble. He pulled sulfur and acid onto the bears or pretending to feed them.
What an shame! Animals are our friends and something must be done to prevent them from being injured.
Sincerely Yours

高考英语短文改错的解题技巧与方法 摘要：短文改错是近年高考英语测试题中的一个必考题。其目的是考查学生综合运用英语的准确性,测试考生发现、判断纠正文章错误的能力。 关键词：短文改错准确性上下文正确理解行文逻辑 短文改错题是目前高考英语的必考项目，也是平时期中、期末考试的必考题型，短文改错是融语法知识与语言技能为一体的综合性英语试题，旨在考查学生对语言的发现，判断，纠正文章中错误的能力以及对词汇、语法和语篇三要素的把握能力。短文改错其实并非难题，但得分率不高。究其原因，主要与学生对短文改错的特点和做题方法有很大的关系。 一．短文改错设置的错误的主要类型 短文改错设置的错误的主要类型有：⑴名词的单复数；⑵动词的词态和语态；⑶非谓语动词；⑷介词的搭配；⑸主谓一致性；⑹不定冠词与定冠词；⑺固定词组的搭配；⑻行文逻辑一致性；⑼词性的混淆；⑽同义词辨异；⑾连词的误用；⑿代词的格与数；⒀句子成份残缺等。归纳为语法错误、词汇错误和上下文关系错误。这些错误大致涉及以下几个方面：（一）一致性问题 所涉及的一致性问题主要包括主谓一致、时态、语态一致、代词指代一致、名词的数与格的一致、句式结构与语意一致、行文关系的一致。例如：主谓不一致 eg: There were a football game on TV last Saturday evening. 讲解：原句中a football game决定了谓语动词必须用单数，所以应该把were改为was。 （二）词性问题 词性问题不单单是识别的问题，能够说出所给单词的词性，并不说明能够在句中找出用错词性的地方。其主要目的是检测考生是否真正了解主要词类的语法作用及其在句中的经常性位置，如名词在句中一般作主语、宾语、表语，动词作谓语，形容词充当表语、定语和宾补，而副词则充当状语，修饰形容词、动词乃至句子。 名词主要考察能力：单复数混用和出题形式： 单复数混用 eg: Helen is seve nteen year old. She is very busy. 讲解：“年龄多大了”应该为复数形式，应此应该把year改为years。注意：代词单复数混用类似。 eg: As for a friendship, we can readily find them in our classmates and other people ar ound us. 讲解：显然因该把them改为it，指代前面提及的friendship。此句话意思是“就友谊来说，我们可以很容易地从我们的同学和周围的人中找到。” 形容词/副词主要考察能力：两者之间是否混用。 出题形式：形容词与副词混用。即该用形容词的地方原文用了副词，该用副词的地方原文用了形容词。 ①副词代替正确形容词出现在文章当中 eg: During the football season, Helen is much busier than usually. 讲解：很明显“与平时相比较更忙”，因此需要把usually改为usual。 ②形容词代替正确副词出现在文章当中 eg: As the time clock showed one minute an d forty-two seconds left in the game, she began cheering excited,“Come on-get going!”
1. Three friends and I was driving on a highway. While we were going at least 50 miles per hour, we passed over a car. It had broken down, stopped on the side of the road. My friend slows down, and pulled behind the other car. He got out of the car immediate and before I knew it he was helping the other person push the car down the road to a spot where wasn’t so close to the passing cars. From the way they were pushing the car, it looked as if my friend was pushing them all by himself. I thought my friend help a complete stranger like this was a great thing, but I won’t forget his good nature or character. 2. Dear Brad, I’m very glad to hear from you. In your last letter you ask about the post-80s in China. Actually I am the boy who belongs to this group. Comparing with our parents, life for us is getting much hard. The job market is tough and the house is expensively to afford. Now many girls prefer to marry with a man who owns a house an d a car. Therefore, I don’t think love built on house and cars is true love, and I doubt how long it will last. As a matter of fact, though situations are tough today, a lot of we post-80s are making great efforts live a good life. I believe we will have a nice future. Li Hua 3. Good morning, ladies and gentlemen, Some of us are having problems about our parents, as they often look into our school bags or read our diaries. I fully understand why we are comfortable about it, but it is no need to feel too sadly. Our parents are checking in our bags or diaries to make sure we’re not getting into troubles. They have probably heard of some horrible stories about other kids and thinking we might do the same. Or perhaps they just want to connect with us and are doing it all wrong. My suggestion is: Tell them we want them to trust us as many as we’d like to trust them. If you don’t think you can talk to them, write them a letter and leave it lie around --- they are bound to read it. Thank you! 4. We spend two weeks in London last year. We went there in the autumn .We think it is the best season to visit England. The weather is usually good but there aren’t too many tourists in October. We stayed in a small h otel in the West End .It was convenient as we did most of our traveling by foot. We went to look at the places where all tourists see. We saw Buckingham Palace and the National Gallery. We went to shopping in Oxford Street and spent too many money .What we liked most, though, was going to theatre. We don’t have the chance to see so wonderful plays at home .A lot of people say English food is very badly. We didn’t think so. It’s true that most of the restaurants are French or Italian or Chinese, but we had some very good meal.
高三英语短文改错专项训练(每日一篇） (1) Last Sunday I saw the worst storm in years. It came sudden and went on for over three hours. After lunch, I went into my room to have a rest. The air was hotter, and all is quiet. Then a strong wind started to blow into my room. Pieces of paper on my desk flew high into the air and some flew out the open window. As I ran out to catch them, big drop of rain began to fall. When I came back into house, it was raining harder and harder. I tried very hard to close the window.

Most of his students are from other part of China and have come to Beijing at a very young age of sixteen or seventeen. He hopes create an environment for his students that it is much more relaxing than the one he used to study in. He thought that an actor should relax himself when performing. Yet his students deep respect him and he never needs to raise his voice in order to be hearing. For his opinion, actors should go on even when they feel they have made a mistake in their performances because the moment is already gone but people can never be back to it. . . So art is always changing and
Last week my parents and I took a two-days trip to Emei Mountain in Sichuan. As every one knows, it’s famous mountain with all kinds of plants and animals. The weather was fine. It was about noon we arrived at the foot of the mountain. The three of them were very excited. As we climbed the mountain, we fed monkeys, visiting temples and told stories. On the way up I was busy taking picture since the scenery was so beautiful. The time passes quickly. Evening came down. We spent the night in a hotel at the top of the mountain. The food was expensive and the service was good. I was so tired that I fell asleep at the moment my head touched the pillow. （二） Many teachers worry about the effects of television with young people. According to studies, many children spend more time watching television than they spend in school. Because so much viewing, children may not be develop the habit of read and the ability to enjoy themselves. No one worries much about the radio program young people listen to, although radios can be very noise. Teachers also wonder about the effects of television commercials. On one year the average child will see 25,000 television commercials, all planned and written by grown-ups to make children to want things that they don't real need. （三） I’m the captain o f our school team so with my fellow players we’ve won sever al games.

He wanted to make their parents happy. (四) When I first learned to write English, I ran into many difficulties . The main problem was in that I always thought in Chinese and tried to translate anything into English. My teacher advised me to keep my diary.

Soon I began to enjoy talk to myself on paper as I was learning to express me in simple English .One day I wrote a little story and showed to my teacher .She liked it very much and reads it to the class .All said the story was a good one. Their word were a great encouragement to me. （五） Dear Ralph, I’m a newcomer here of a small town. I would describe myself as shy and quietly. Before my classmates, it seems always difficult for me to do things as well them. I'm sure they will laugh to me and see me as a fool. So I feel happy every day. Besides, I have few friends. I don't know that they don't like to talk with me. Sometimes, we talked to each other very well in class, but after class we become stranger at once. I am trying to improve the situation since it doesn’t seem to work. Can you tell me about what I should do? Yours, Xiao Wei
