The Development of Writing
Few people would disagree with the belief that primitive man learned to speak long before he developed a system of writing. But while his early spoken language may have been nothing more than a few sounds, early man could transmit messages across distances by means of signals from drums, smoke and fire. It was probably a desire to record messages that led to the development of alphabets. For early man, who could speak and who could send messages, could not put those messages into permanent form. The desire to have permanent records may not be easily understood in today’s world where electronic science has made disk and tape recordings commonplace. If early man wanted to leave records of past events to remind him of good times and bad, he had to depend on his memory, and on primitive markings such as piles of stones, cuttings on sticks, etc. The limitations of this system led early man to turn to rock drawings for the expression of sophisticated ideas. This form of writing depended on pictures to convey ideas, and although more advanced than previous developments, it was still too limited for man to be entirely satisfied. Man finally was able to develop a system of picture writing that associated symbols and sound. This system, which was originated by the early Sumerians and the Egyptians more than 3,000 B.C., is based on the same principle that we sue today in most world alphabets. It was about 1,000 B.C. that the Phoenicians took the complicated picture alphabets of the Egyptians and simplified then into about 30 symbols, each one standing for a
consonant sound. Finally, the ancient Greeks, about 800 B.C., refined this Phoenician alphabet and added signs for vowel sounds. The alphabet used in English, an din many other world languages, is called the Roman alphabet because it was developed by the Romans who had taken most of it from another Italic people, the Etruscan, who, in their turn, had learned it from the ancient Greeks. Letters on ancient monuments in Rome prove that the Roman alphabet, the same alphabet used today, had been perfected by A.D. 114.
Secret to Longevity Lies in Genes, Study Finds

WASHINGTON (Reuters) Want to live to be 100? Pick old grandp arents. It’s an old irony, but researchers said on Tuesday they had shown this is remarkably true when it comes to surviving into old age, and they believe a cluster of just a few genes may be responsible. They have set up a company that studies centenarians to see if the generic secret to living a long and healthy life may result in drugs that can prevent the diseases of aging, such as Alzheimer’s and heart disease. "It isn’t really that obvious," Dr. Thomas Perls, who led the study, said in a telephone in terview. "It isn’t old age that runs in families. It’s exceptional old age that runs in families. We think this may be a handful
of genes that could be playing really substantial roles in the ability to get to very old age, much of it in good health."
Perl’s team at Harvard University and Beth Israel Deaconess Medical School studied 444 families, including more than 2,000 relatives of people who live to 100. Demographer John Wilmoth of the University of California Berkeley compared this data to the 1900 census and the Social Security Administration database. "Female siblings had death rates at all ages at about one-half the national level," they wrote in their report, published in this week issue of the Proceedings of the National Academy of Sciences. "Male siblings of centenarians were at least 17 times as likely to attain age 100 themselves, while female siblings were at least eight times as likely." Perls is not interested in extending life at any cost.
WHO WANTS TO GET THAT OLD, ANYWAY?
"People might think, who wants to live to 100 anyway? because people get the idea that the older you get, the sicker you get." But his study found just the opposite. "You can get Alzheimer, stroke, cancer in your 60s and 70s and expect to live another 30,40 years." Earlier work has shown many of these people share similarities in their DNA, especially on chromosome 4. Perls hopes his company, Centagenetix (http:/https://www.doczj.com/doc/d916734984.html,) can home in on the important genes and perhaps make discoveries that will lead to drugs that can stave off disease.
"Discovering these genes will lead to understanding the biochemical
pathways that those genes affect," he said. "My hope is that that would help a lot of other people age more slowly and delay and, my goodness even escape, something like Alzheimer."
Which genes you do not have may be as important as those you do, Perls said. For instance, he found the 100-year-olds were very unlikely to have a version of a gene called APOE-4, which is associated with high cholesterol and Alzheimer. Environment did not seem to be too important to those who lived to be 100. Census Bureau data showed they were more likely to be poor and poorly educated ?something not usually associated with old age.
But for most of us, environment and behavior is key. "I think the average set of genes gets us to our mid- to late-80s," said Perls, a geriatrician who now works at Boston Medical Center. "I base this on twin studies and on Seventh Day Adventists, who have a life expectancy of 87 years, who do everything right。They smoke, they are lean, they are vegetarian, they exercise and as a result they live 10 years longer than the rest of us. That basically tells us what our genes are capable of. But to live the extra 15, 20 years beyond that, I suspect genes are playing a greater role."
So That Nobody Has To Go To School If They Don't Want
by Toby Roger Sipher
A decline in standardized test scores is but the most recent indicator that American education is in trouble.
One reason for the crisis is that present mandatory-attendance laws force many to attend school who have no wish to be there. Such children have little desire to learn and are so antagonistic to school that neither they nor more highly motivated students receive the quality education that is the birthright of every American.
The solution to this problem is simple: Abolish
compulsory-attendance laws and allow only those who are committed to getting an education to attend.
This will not end public education. Contrary to conventional belief, legislators enacted compulsory-attendance laws to legalize what already existed. William Landes and Lewis Solomon, economists, found little evidence that mandatory-attendance laws increased the number of children in school. They found, too, that school systems have never effectively enforced such laws, usually because of the expense involved.
There is no contradiction between the assertion that compulsory attendance has had little effect on the number of children attending school and the argument that repeal would be a positive step toward improving education. Most parents want a high school education for their children. Unfortunately, compulsory attendance hampers the ability
of public school officials to enforce legitimate educational and disciplinary policies and thereby make the education a good one.
Private schools have no such problem. They can fail or dismiss students, knowing such students can attend public school. Without compulsory attendance, public schools would be freer to oust students whose academic or personal behavior undermines the educational mission of the institution.
Has not the noble experiment of a formal education for everyone failed? While we pay homage to the homily, "You can lead a horse to water but you can't make him drink," we have pretended it is not true in education.
Ask high school teachers if recalcitrant students learn anything of value. Ask teachers if these students do any homework. Quite the contrary, these students know they will be passed from grade to grade until they are old enough to quit or until, as is more likely, they receive a high school diploma. At the point when students could legally quit, most choose to remain since they know they are likely to be allowed to graduate whether they do acceptable work or not.
Abolition of archaic attendance laws would produce enormous dividends.
First, it would alert everyone that school is a serious place where one goes to learn. Schools are neither day-care centers nor indoor street corners. Young people who resist learning should stay away; indeed, an end to compulsory schooling would require them to stay away.
Second, students opposed to learning would not be able to pollute the educational atmosphere for those who want to learn. Teachers could stop policing recalcitrant students and start educating.
Third, grades would show what they are supposed to: how well a student is learning. Parents could again read report cards and know if their children were making progress.
Fourth, public esteem for schools would increase. People would stop regarding them as way stations for adolescents and start thinking of them as institutions for educating America's youth.
Fifth, elementary schools would change because students would find out early they had better learn something or risk flunking out later. Elementary teachers would no longer have to pass their failures on to junior high and high school.
Sixth, the cost of enforcing compulsory education would be eliminated. Despite enforcement efforts, nearly 15 percent of the school-age children in our largest cities are almost permanently absent from school.
Communities could use these savings to support institutions to deal with young people not in school. If, in the long run, these institutions prove more costly, at least we would not confuse their mission with that of schools.
Schools should be for education. At present, they are only tangentially so. They have attempted to serve an all-encompassing social function, trying to be all things to all people. In the process they
have failed miserably at what they were originally formed to accomplish.
Write a summary of the following passage in less than 100 words.
A great part of Arabia is desert. Here there is nothing but sand and rock. The sand is so hot that you cannot walk over it with your bare feet in the daytime. Here and there in the desert are springs of water that come from deep down under the ground--- so deep that the sun cannot dry them up. There springs are few and far apart, but wherever there is one, green grass very soon covers the ground all around it. Soon fig trees and palm trees grow tall and graceful, making a cool, green, shady place around the spring. Such a place is called an oasis.
The Arabs who are not in the cities live in the desert all the year round. They live in tents that can be put up and taken down very easily and quickly so that they can move from one oasis to another, seeking grass and water for their sheep, goats, camels and horses. These desert Arabs eat ripe, sweet figs, and also the dates that grow upon the palm trees; they dry them , too, and use them as food all the year round.
These Arabs have the finest horses in the world. An Arab is very proud of his riding horse, and loves him almost as much as he loves his wife and children. He never puts heavy loads upon his horse, and often lets him stay in the tent with his family.
The camel is much more useful to the Arab than his beautiful horse, however, for he is much larger and stronger. One camel can carry as much as or more than tow horses. The Arab loads the camel with goods, and rides him, too, for miles and miles across the desert---just as if he were really the “Ship of the Desert”, which he is often called.
Summary 2
Dr. Thomas Perls and researchers have been doing studies and tests to see if genes have anything to do with growing old. Dr. Thomas believes that not only good health, but genes could play a role. Their research has shown that many of the people that live to 90 and over share similarities in their DNA. Dr. Perls hopes that if genes have anything to do with aging then they might be able to understand biochemical pathways.
Summary 3
Roger Sipher makes his case for getting rid of compulsory-attendance laws in primary and secondary schools with six arguments. These fall into three groups—first that education is for those who want to learn and by including those that don't want to learn, everyone suffers. Second, that grades would be reflective of effort and elementary school teachers wouldn't feel compelled to pass failing students. Third, that schools would both save money and save face with the elimination of compulsory-attendance laws.
Summary4
Though most part of Arabia is desert, oases still exist, where the Arabs live. They live in tents, seeking grass and water for their animals in oases, and they themselves eat fruits of the green trees there for food. The Arabs never load or ride their horses because they love them so much; while the camel is more useful for them to carry goods across the desert.

Original: My neighbor's children love playing hide-and-seek as all children do, but no one imagine that a game they played last week would be reported in the local newspaper. One afternoon, they were playing in the vacant lot down the corner. Young Paul, who is only five years old, found the perfect place to hide. His sister, Natalie, had shut her eyes and was counting to ten when Paul noticed the storage mail box at the corner and saw that the metal door was standing open. The mailman had just taken out several sacks of mail and had carried them to his truck which was standing at the curb a few feet away. Paul climbed into the storage box and pulled the door closed so hard that it locked. Soon realizing what he had done, he became frightened and started crying. Meanwhile, Natalie was looking for him everywhere but could not find him. It was lucky that she happened to pause at the corner for a minute and heard her brother's cries. She immediately ran to tell the mailman who hurried back from his truck to unlock the metal door. Paul was now free, but he had had such a bad scare that he could not stop crying. The mailman, however, soon found a way of making him laugh again. He told him that the next time he wanted to hide in a mail box, he should remember to put a stamp on himself! Summary: The children were playing hide-and-seek in a vacant lot one afternoon. Finding that the storage mailbox had been left open, Paul hid and locked himself in it accidentally. His sister, Natalie, heard his cries and realized where he was hiding, so she immediately told the mailman to unlock the metal door. After letting him out, the mailman made him stop crying by telling him to put a stamp on himself the next he wanted to hide in a mailbox. Original: Why do some animals die out? In the past two hundred years people have caused many kinds of animals to die out--to become extinct. People keep building houses and factories in fields and woods. As they spread over the land, they destroy animals' homes. If the animals can't find a place to live, they die out. Sixteen kinds of Hawaiian birds have become extinct for this reason. Other animals, such as the Florida Key deer, may soon die out because they are losing their homes.Hunters have caused some animals to become extinct, too. In the last century, hunters killed all the passenger pigeons in North America and most of the buffalos. Today they are fast killing off hawks and wolves. Pollution is killing many animals today, too. As rivers become polluted, fish are poisoned. Many die. Birds that eat the poisoned fish can't lay strong, healthy eggs. New birds aren’t born. So far, no animals have become extinct because of pollution. But some, such as the bald eagle and the brown pelican, have become rare and may die out. Scientists think that some animals become extinct because of changes in climate. The places where they live become hotter or cooler, drier or wetter. The food that they eat cannot grow there any more. If the animals can't learn to eat something else, they die. Dinosaurs may have died out for this reason. Summary:
Steps to Writing a Summary 1.Read and understand the prompt or writing directions. What are you being asked to write about? Example: Summary of an Article Write a summary of the article. Your writing will be scored on how well you: ?state the main ideas of the article; ?identify the most important details that support the main ideas; ?write your summary in your own words, except for quotations; and ?express the underlying meaning of the article, not just the superficial details. 2. Read, think about, and understand the text. Review the material to make sure you know it well. Use a dictionary or context clues to figure out the meaning of any important words that you don’t know. 3. Take notes. Write down the main ideas and important details of the article. 4.Write a thesis statement. In a single sentence, state the main idea of the article. The thesis statement should mention the underlying meaning of the article, not just the superficial details. 5. Organize and outline ideas. Write down the important details you need to include in the summary. Put them in a logical order. Topic Sentence: Evidence: #1: #2: #3: 6.Write your essay. ?Your summary should be about one third of the length of the original article. ?Focus on the main point of the article and the most important details. ?Use your own words; avoid copying phrases and sentences from the article unless they’re direct quotations. 7.Revise. Have you indented all paragraphs? Have you captured the main point of the article? Have you included the most important details? Is there sentence variety? Have you avoided writing short, choppy sentences? Are there transitional words and phrases to connect ideas? 8. Proofread and edit. Check your spelling, grammar, and punctuation. Is the verb tense consistent? Are all names spelled correctly and capitalized? Have you avoided writing run-on sentences and sentence fragments? 9. Write your draft. Use blue or black ink. Skip lines. Write on one side of the paper only. Include a title on the top line. 10. Read your summary one last time before you turn it in. Look for careless spelling, punctuation, and grammar errors, especially omitted words or letters. Cross out errors neatly with a single line and write the correction above. Original Article: Bats In the distant past, many people thought bats had magical powers, but times have changed. Today, many people believe that bats are rodents, that they cannot see, and that they are more likely than other animals to carry rabies. All of these beliefs are mistaken. Bats are not rodents, are not blind, and are no more likely than dogs and cats to transmit rabies. Bats, in fact, are among the least understood and least appreciated of animals. Bats are not rodents with wings, contrary to popular belief. Like all rodents, bats are mammals, but they have a skeleton similar to the human skeleton. The bones in bat wings are much like those in arms and the human hand, with a thumb and four fingers. In bats, the bones of the arms and the four fingers of the hands are very long. This bone structure helps support the web of skin that stretches from the body to the ends of the fingers to form wings. Although bats cannot see colors, they have good vision in both dim and bright light. Since most bats stay in darkness during the day and do their feeding at night, they do not use their vision to maneuver in the dark but use a process called echolocation. This process enables bats to emit sounds from their mouths that bounce off objects and allow them to avoid the objects when flying. They use this system to locate flying insects to feed on as well. Typically, insect-eating bats emerge at dusk and fly to streams or ponds where they feed. They catch the insects on their wingtip or tail membrane and fling them into their mouths while flying. There are about 1,000 species of bat, ranging in size from the bumblebee bat, which is about an inch long, to the flying fox, which is sixteen inches long and has a wingspan of five feet. Each type of bat has a specialized diet. For seventy percent of bats, the diet is insects. Other types of bats feed on flowers, pollen, nectar, and fruit or on small animals such as birds, mice, lizards, and frogs. (continued on back)

英文Summary写作方法、范例及常用句式
摘要是对一篇文章的主题思想的简单陈述。它用最简洁的语言概括了原文的主题。写摘要主要包括三个步骤：（1）阅读；（2）写作；（3）修改成文。 第一步：阅读 A．认真阅读给定的原文材料。如果一遍不能理解，就多读两遍。阅读次数越多，你对原文的理解就越深刻。 B．给摘要起一个标题。用那些能概括文章主题思想的单词、短语或短句子作为标题。也可以采用文中的主题句作为标题。主题句往往出现在文章的开头或结尾。一个好标题有助于确定文章的中心思想。C．现在，就该决定原文中哪些部分重要，哪些部分次重要了。对重要部分的主要观点进行概括。 D．简要地记下主要观点——主题、标题、细节等你认为对概括摘要重要的东西。 第二步：动手写作 A. 摘要应该只有原文的三分之一或四分之一长。因此首先数一下原文的字数，然后除以三，得到一个数字。摘要的字数可以少于这个数字，但是千万不能超过这个数字。 B. 摘要应全部用自己的话完成。不要引用原文的句子。 C. 应该遵循原文的逻辑顺序。这样你就不必重新组织观点、事实。 D. 摘要必须全面、清晰地表明原文所载的信息，以便你的读者不需翻阅原文就可以完全掌握材料的原意。 E. 写摘要时可以采用下列几种小技巧：
1) 删除细节。只保留主要观点。 2) 选择一至两个例子。原文中可能包括5个或更多的例子，你只需从中筛选一至二个例子。 3) 把长段的描述变成短小、简单的句子。如果材料中描述某人或某事用了十个句子，那么你只要把它们变成一两句即可。 4) 避免重复。在原文中，为了强调某个主题，可能会重复论证说明。但是这在摘要中是不能使用的。应该删除那些突出强调的重述句。 5) 压缩长的句子。如下列两例： “His courage in battle might without exaggeration be called lion-like.” 可以概括为：”He was very brave in battle.” “He was hard up for money and was being pressed by his creditor.”可以概括为：“He was in financial difficulties.” 6) 你还可以使用词组代替整句或者从句。请看下面的例子：“Beautiful mountains like Mount Tai, Lushan Mountain, and Mount Huang, were visited by only a few people in the past. Today, better wages, holidays with pay, new hotels on these mountains, and better train and bus services, have brought them within reach of many who never thought of visiting them ten years ago.” 可以概括为：”Beautiful mountains like Mount Tai, once visited by only a few people, are today accessible to many, thanks to better wages, paid holidays, new hotels and better transportation services.”

摘要是对一篇文章的主题思想的简单陈述。它用最简洁的语言概括了原文的主题。写摘要主要包括三个步骤： （1）阅读； （2）写作； （3）修改成文。 第一步： 阅读 A．认真阅读给定的原文材料。如果一遍不能理解，就多读两遍。阅读次数越多，你对原文的理解就越深刻。 B．给摘要起一个标题。用那些能概括文章主题思想的单词、短语或短句子作为标题。也可以采用文中的主题句作为标题。主题句往往出现在文章的开头或结尾。 一个好标题有助于确定文章的中心思想。 C．现在，就该决定原文中哪些部分重要，哪些部分次重要了。对重要部分的主要观点进行概括。 D．简要地记下主要观点——主题、标题、细节等你认为对概括摘要重要的东西。 第二步： 动手写作 A.摘要应该只有原文的三分之一或四分之一长。因此首先数一下原文的字数，然后除以三，得到一个数字。摘要的字数可以少于这个数字，但是千万不能超过这个数字。 B.摘要应全部用自己的话完成。不要引用原文的句子。
C.应该遵循原文的逻辑顺序。这样你就不必重新组织观点、事实。 D.摘要必须全面、清晰地表明原文所载的信息，以便你的读者不需翻阅原文就可以完全掌握材料的原意。 E.写摘要时可以采用下列几种小技巧： 1)删除细节。只保留主要观点。 2)选择一至两个例子。原文中可能包括5个或更多的例子，你只需从中筛选一至二个例子。 3)把长段的描述变成短小、简单的句子。如果材料中描述某人或某事用了十个句子，那么你只要把它们变成一两句即可。 4)避免重复。在原文中，为了强调某个主题，可能会重复论证说明。但是这在摘要中是不能使用的。应该删除那些突出强调的重述句。 5)压缩长的句子。如下列两例： “Hiscourageinbattlemightwithoutexaggerationbecalledlion-like.”可以概括为：”He was very brave in battle.” “He was hard up for money and was being pressed by his creditor.”可以概括为： “He was in financial difficulties.” 6)你还可以使用词组代替整句或者从句。请看下面的例子： “BeautifulmountainslikeMountTai,LushanMountain,andMountHuang,were visited by only a few people in the past. Today, better wages,holidays with pay, new hotels on these mountains, and better train andbus services, have brought them within reach of many who never thoughtof visiting them ten years ago.” 可以概括为：
