阅读下面的短文，然后按照要求写一篇150词左右的英语短文。 Getting up early has been regarded as a good habit since ancient times. Many years ago, people thought that if we went to bed early and got up early, we would be energetic the whole day. So, getting up early is of great importance to us all. In fact, morning is the best time of a day. In the morning, the air is the freshest and people are usually in the best conditions. Many of us may have the experiences that we memorize some things more quickly and accurately in the morning than at any other time of the day. If we do some morning exercise or only take a short walk in the morning, we can build our bodies and become much healthier. Also we will have enough time to make a plan and get ready for our work or study of the day if we get up early. However, if we get up late, we'll probably have to do everything in a great hurry. Let us remember getting up early is a good habit and try our best to keep it. if we stick to getting up early every day, we will certainly benefit a lot from it. 【写作内容】 (1)以约30个词概括短文的要点： (2)然后以约120个词就“早起还是晚起好”这个主题发表你的看法，并包括以下要点： ①你是喜欢早起还是晚起； ②结合自己学习或生活的例子，说明你喜欢这样做的理由： ⑧你的父母或教师有何建议： ④你如何看待他们的建议? 【写作要求】 （1）可以使用实例或其它论述方法支持你的论点，也可以参照阅读材料的内容，但不得直接引用原文中的句子： (2)标题白定。 【评分标准】 概括准确、语言规范、内容合适、篇章连贯。

But their grim legacy remains in the language we speak. The rescued dogs, cats, rabbits and horses who live with so many of us today ultimately owe their survival to British reformers, writes Kathryn Shevelow in For the Love of Animals: The Rise of the Animal Protection Movement. These men and women, she writes, “forced the law for the first time to become responsive to the plight of animals.” B. Dewey: The Small-Town Library Cat Who Touched the World By Vicki Myron with Bret Witter Grand Central Publishing 277 pp. $19.99 C. I once interviewed a little girl who lived in a run-down trailer. Her family faced every kind of economic and social deprivation you can imagine, yet she was bright and cheerful with a cherished plan for her adult years. “I’m going to have a job that has to do with rescuing animals,” she confided in me. How many of us there must be – we who dream of saving the animals! That means that, potentially, there’s a huge audience for Benjamin Mee’s real-life animal-rescue story We Bought a Zoo. D. "The heartwarming and true story of Wesley, a barn owl, and his human friend and biographer, Stacey O'Brien. Ms. O'Brien, a biologist, rescued Wesley as an injured owlet, and this wonderful book reveals insights into owl behavior gained through her 19 years living with Wesley. Her words say it best: "He was my teacher, my companion, my child, my playmate, my reminder of God."" E. A former Wall Street Journal nature columnist and author of the best-selling “Red-Tails in Love,” Winn once again tackles urban wildlife with gusto. Winn’s engaging tales begin with her love of bird watching, but as she trains her binoculars she discovers that she’s not alone in her urban oasis. Through her curiosity for nature, she finds other like-minded people – citizen scientists – whom she befriends. Together they gather at night to identify moths’ wing patterns and watch with fascination the mysterious mating rituals between two slugs hanging from a tree limb. F. It should surprise no one that the best way to preserve nature is to ensure that all of its parts are in place. But the reality is that humans have long been waging a war against large carnivores – lions and tigers and bears, to name but a few. The result, says author William Stolzenburg in this absorbing and delightful work of natural history, is that we have thrown the balance of nature out of whack. The science he presents is not all new, but the scientific perspective Stolzenburg reflects will be fresh and illuminating to many readers.

Susan Sontag (1933—2004) was one of the most noticeable figures in the world of literature. For more than 40 years she made it morally necessary to know everything — to read every book worth reading, to see every movie worth seeing. When she was still in her early 30s, publishing essays in such important magazines as Partisan Review, she appeared as the symbol of American culture life, trying hard to follow every new development in literature, film and art. With great effort and serious judgment, Sontag walked at the latest edges of world culture. Seriousness was one of Sontag’s lifelong watchwords (格言), but at a time when the barriers (障碍)between the well-educated and the poor-educated were obvious, she argued for a true openness to the pleasure of pop culture. In “Notes Camp”, the 1964 essay that first made her name, she explained what was then a little-known set of difficult understandings, through which she could not have been more famous. “Notes on Camp”, she wrote, represents “a victory of ‘form’ over ‘content’, ‘beauty’ over ‘morals’ ”. By conviction (信念) she was a sensualist(感觉论者), but by nature she was a moralist(伦理学者), and in the works she published in the 1970s and 1980s , it was the latter side of her that came forward. In illness as Metaphor —published in 1978, after she suffered cancer—she argued against the idea that cancer was somehow a special problem of repressed personalities (被压抑的性格), a concept that effectively blamed the victim for the disease. In fact, re-examining old positions was her lifelong habit. In America, her story of a 19th century Polish actress who set up a perfect society in California, won the National Book Award in 2000. But it was as a tireless all-purpose cultural view that she made her lasting fame. “Sometimes,” she once said,“I feel that, in the end, all I am really defending …is the idea of seriousness, of true seriousness.” And in the end, she made us take it seriously too. 1.The underlined sentence in paragraph 1 means Sontag ______. A. was a symbol of American cultural life B. developed world literature, film and art C. published many essays about world culture D. kept pace with the newest development of world culture 2.She first won her name through ___________. A. her story of a Polish actress B. her book illness as Metaphor C. publishing essays in magazines like partisan Review D. her explanation of a set of difficult understandings 3.According to the passage, Susan Sontag ________. A. was a sensualist as well as a moralist B. looked down upon the pop culture C. thought content was more important than form D. blamed the victim of cancer for being repressed 4.As for Susan Sontag’s lifelong habit, she __________. A. misunderstood the idea of seriousness B. re-examined old positions C. argued for an openness to pop culture D. preferred morals to beauty 5.Susan Sontag’s lasting fame was made upon___________. A. a tireless, all-purpose cultural view B. her lifelong watchword：seriousness C. publishing books on morals D. enjoying books worth reading and movies worth seeing
Short and shy, Ben Saunders was the last kid in his class picked for any sports team. “Football, tennis, cricket—anything with a round ball, I was useless,” he says now with a laugh. But back then he was the object of jokes in school gym classes in England’s rural Devonshire. It was a mountain bike he received for his 15th birthday that changed him. At first the teen went biking alone in a nearby forest. Then he began to cycle along with a runner friend. Gradually, Saunders set his mind building up his body, increasing his speed, strength and endurance. At age 18, he ran his first marathon. The following year, he met John Ridgway, who became famous in the 1960s for rowing an open boat across the Atlantic Ocean. Saunders was hired as an instructor at Ridgway’s school of Adventure in Scotland, where he learned about the older man’s cold-water exploits (成就). Intrigued, Saunders read all he could about Arctic explorers and North Pole expeditions, then decided that this would be his future. Journeys to the Pole aren’t the usual holidays for British country boys, and many people dismissed his dream as fantasy. “John Ridgway was one of the few who didn’t say, ‘You are completely crazy,’ ” Saunders says. In 2001, after becoming a skilled skier, Saunders started his first long-distance expedition toward the North Pole. He suffered frostbite, had a closer encounter(遭遇) with a polar bear and pushed his body to the limit. Saunders has since become the youngest person to ski alone to the North Pole, and he’s skied more of the Arctic by himself than any other Briton. His old playmates would not believe the transformation. This October, Saunders, 27, heads south to explore from the coast of Antarctica to the South Pole and back, an 1800-mile journey that has never been completed on skis. 1.The turning point in Saunders’ life came when _______. A. he started to play ball games B. he got a mountain bike at age 15 C. he ran his first marathon at age 18 D. he started to receive Ridgway’s training 2.We can learn from the text that Ridgway _______. A. dismissed Saunders’ dream as fantasy B. built up his body together with Saunders C. hired Saunders for his cold-water experience D. won his fame for his voyage across the Atlantic 3.What do we know about Saunders? A. He once worked at a school in Scotland. B. He followed Ridgway to explore the North Pole. C. He was chosen for the school sports team as a kid. D. He was the first Briton to ski alone to the North Pole. 4.The underlined word “Intrigued” in the third paragraph probably means_______. A. Excited B. Convinced C. Delighted D. Fascinated 5.It can be inferred that Saunders’ journey to the North Pole ________. A. was accompanied by his old playmates B. set a record in the North Pole expedition C. was supported by other Arctic explorers D. made him well-known in the 1960s
Among rich countries, people in the United States work the longest hours. They work much longer than in Europe. This difference is quite surprising because productivity per hour worked is the same in the United States as it is in France, Spain and Germany, and it is growing at a similar speed. In most countries and at most times in history, as people have become richer they have chosen to work less. In other words they have decided to “spend” a part of their extra income on a fuller personal life. Over the last fifty years Europeans have continued this pattern, and hours of work have fallen sharply. But not in the United States. We do not fully know why this is. One reason may be greatly lower taxes in America, which increase the rewards to work. Another may be more satisfying work, or less satisfying personal lives. Longer hours do of course increase the GDP (国内生产总值). So the United States has produced more per worker than, say, France. The United States also has more of its people at work, while in France many more mothers and older workers have decided to stay at home. The overall result is that American GDP per head is 40% higher than in France, even though productivity per hour worked is the same. It is not clear which of the two situations is better. As we have seen, work has to be compared with other values like family life, which often get lost in interest. It is too early to explain the different trends（趋势）in happiness over time in different countries. But it is a disappointing idea that in the United States happiness has made no progress since 1975, while it has risen in Europe. Could this have anything to do with trends in the work-life balance? 1.From the text we know that the author . A. believes that longer working hours is better B. prefers shorter working hours to longer ones C. says nothing certain about which pattern is better D. thinks neither of the patterns is good 2.Which of the following countries has more of its people at work? A. Spain. B. France. C. Germany. D. America. 3.In the last paragraph, the underlined word “which” refers to ______. A. family life B. situations C. other values D. trends 4.What message can we get from the text? A. The GDP of Europe is higher than that of America. B. Two possible reasons are given for working longer hours in the US. C. People all over the world choose to work less when they are richer. D. Americans are happier than Europeans. 5.Which of the following would be the best title for the text? A. Americans and Europeans B. Staying at Home C. Work and Productivity D. Work and Happiness

When that happens, it is 1to think that it was a mistake to try to read it, but that was not the mistake. The mistake was in 2too much from the first reading of a(n) 3book. If you read it in the right way, no book written for the 4reader, no matter how difficult, need be a cause for despair (绝望). What is the right method? The 5is an important and helpful rule of reading that is either not known or often forgotten. That rule is simply this: when reading a difficult book for the first time, read it through without ever 6to think about the things that you do not understand immediately. Do not be stopped by what you can't understand. Read through the difficult 7, and you’ll soon come to things that you do understand. Read these 8. You will have a much better chance of understanding all of the book when you read it again, but that 9you to have read the book through once 10. What you understand by reading the book through to the 11will help you when you try later to read the places that you did not 12in your first reading. Or if you never re-read the book, understanding half of it is much better than understanding nothing of it, which will happen if you allow yourself to be stopped by the first difficult part of the book. Most of us were taught to 13the things that we do not understand. We were told to find the 14of unfamiliar words, and to try to find an explanation in another 15for anything that we did not understand in the book that we were reading. But when these things are done before the proper time, they only harm our reading, instead of helping it.

Sports shoes that find out whether their owner has enough exercise to warrant time in front of the television have been devised in the UK. The shoes — named Square Eyes — contain an electronic pressure sensor and a tiny computer chip to record how many steps the wearer has taken in a day. A wireless transmitter passes the information to a receiver connected to a television, and this decides how much evening viewing time the wearer deserves, based on the day’s efforts. The design was inspired by a desire to fight against the rapidly ballooning waistlines among British teenagers, says Gillian Swan, who developed Square Eyes as a final year design project at Brunel University to London, UK. “We looked at current issues and childhood overweight really stood out,” she says. “And I wanted to tackle that with my design.” Once a child has used up their daily allowance gained through exercise, the television automatically switches off. And further time in front of the TV can only be earned through more steps. Swan calculated how exercise should translate to television time using the recommended(推荐) daily amounts of both. Health experts suggest that a child take 12,000 steps each day and watch no more than two hours of television. So, every 100 steps recorded by the Square Eyes shoes equals precisely one minute of TV time. Existing pedometers （计步器） normally clip onto a belt or slip into a pocket and keep count of steps by measuring sudden movement. Swan says these can be easily tricked into recording steps through shaking. But her shoe has been built to be harder for lazy teenagers to cheat. “It is possible, but it would be a lot of effort,” she says. “That was one of my main design considerations.”
1.According to Swan, the purpose of her design project is to ____. A．keep a record of the steps of the wearer B．deal with overweight among teenagers C．prevent children from being attracted by the TV programs. D．prevent children from being tricked by TV programs 2.Which of the following is true of Square Eyes shoes? A．They control a child’s evening TV viewing time. B．They determine a child’s daily pocket money. C．They have raised the hot issue of overweight. D．They contain information of the receiver. 3.What is emphasized by health experts in their suggestion? A．The exact number of steps to be taken. B．The exact number of hours spent on TV. C．The proper amount of daily exercise and TV time. D．The way of changing steps into TV watching time. 4.Compared with other similar products, the new design ____. A．makes it difficult for lazy teenagers to cheat B．counts the wearer’s steps through shaking C．records the sudden movement of the wearer D．sends teenagers’ health data to the receiver 5.Which of the following would be the best title for the text? A．Smart Shoes Decide on Television Time B．Smart Shoes Guarantee(保证) More Exercise C．Smart Shoes Measure Time of Exercise D．Smart Shoes Stop Childhood Overweight
For many years, scientists couldn't figure out how atoms and molecules on the Earth combined to make living things. Plants, fish, dinosaurs, and people are made of atoms and molecules, but they are put together in a more complicated way than the molecules in the primitive ocean. What's more, living things have energy and can reproduce, while the chemicals on the Earth 4 billion years ago were lifeless. After years of study, scientists figured out that living things, including human bodies, are basically made of amino acids and nucleotide bases. These are molecules with millions of hydrogen, carbon, nitrogen, and oxygen atoms. How could such complicated molecules have been formed in the primitive soup? Scientists were stumped. Then, in 1953, two scientists named Harold Urey and Stanley L. Miller did a very simple experiment to find out what had happened on the Primitive Earth. They set up some tubes and bottles in a closed loop, and put in some of the same gases that were present in the atmosphere 4 billion years ago: water vapor, ammonia, carbon dioxide, methane, and hydrogen. Then they shot an electric spark through the gases to simulate bolts of lightning on the ancient Earth, circulated the gases through some water, sent them back for more sparks, and so on. After seven days, the water that the gases had been bubbling through had turned brown. Some new chemicals were dissolved in it. When Miller and Urey analyzed the liquid, they found that it contained amino acids-the very kind of molecules found in all living things. 1.When did scientists come to realize how the atoms and molecules on the Earth combined to make living thing?
