Rachel Carson, 1907-1964: Her Books Helped Launch the Environmental Protection Movement in the U.S.Her book, "Silent Spring," led the U.S. to ban DDT. ANNOUNCER: People America, a program in Special English on the Voice of America. Today, Steve Ember and Rich Kleinfeldt tell about scientist Rachel Carson. Her work started the environmental protection movement in the ed States. (MUSIC)VOICE ONE: Rachel Carson Rachel Carson was born on May twenty-seventh, nineteen-oh-seven in Springdale, Pennsylvania. Rachel's father, Robert Carson, was a salesman who invested in local land. He purchased twenty-six hectares of land to make a home for his family. The area was surrounded by fields, trees and streams. The Carson family enjoyed living in the beautiful, country environment.Rachel's mother, Maria Carson, had been a schoolteacher. She loved books. She also loved nature. Rachel was the youngest of three children. Her sister and brother were aly in school when she was born. So Missus Carson was able to spend a lot of time with Rachel. She showed Rachel the beauty of nature. She also taught Rachel a deep love for books. Missus Carson became the most important influence on Rachel's life.VOICE TWO:Rachel was a quiet child. She liked to and to write poems and stories. She was very intelligent. At a very early age she decided she wanted to be a writer someday. Her first published story appeared in a children's magazine when she was ten years old. Rachel went to the Pennsylvania College for Women. She studied English because she wanted to become a professional writer. Yet, she felt she did not have the imagination to write creative stories. She changed her area of study from English to science after she took a biology course that she liked. Her professors advised her not to study science. They said there was no future for a woman in science.VOICE ONE:In nineteen twenty-nine, Rachel graduated from college with high honors. She won a financial award to study at Johns Hopkins University in Baltimore, Maryland. In nineteen thirty-two, she earned a master's degree in zoology, the scientific study of animals. She taught zoology at the University of Maryland for a few years. During the summers, she studied the ocean and its life forms at the Woods Hole Marine Biological Laboratory in Massachusetts. That is when she became interested in the mysteries of the sea.(MUSIC)VOICE TWO:Rachel's life changed greatly in the middle nineteen thirties. Her father died suddenly in nineteen thirty-five. He left very little financial support for Rachel's mother. It was during the economic decline in the ed States called the Great Depression. Rachel now had to support her mother and herself. She needed more money than her teaching job could provide. She began part-time work for a federal government agency, the Bureau of Fisheries in Washington, D.C. One year later, Rachel's sister died. Her sister was the mother of two young girls. Rachel and her mother cared for the girls. Rachel now had to support her mother, two nieces and herself. Again, she needed a job with better pay.VOICE ONE:A full time job for a biologist opened at the ed States Bureau of Fisheries. Rachel Carson was the only woman to try for the position. She had the highest score of all the people competing for the job. Miz Carson got the position in August, nineteen thirty-six. She was chosen to work in the office of the chief of the biology division.Her first job was to write a series of programs called "Romance Under the Waters." The series was broadcast on radio for a year. She continued to write and edit publications for the Bureau of Fisheries for many years. The bureau was happy to have a scientist who was also an excellent writer. Rachel Carson provided information to the public in interesting and understandable ways.VOICE TWO:In nineteen forty, the ed States Bureau of Fisheries and the Biological Survey joined to become the Fish and Wildlife Service. Miz Carson continued as one of the few women employed there as a scientist. The other women worked as office assistants.While she was working for the government, Miz Carson wrote at night and on weekends. In nineteen thirty-seven she wrote a report about sea life. It was called Undersea. It appeared in the magazine, Atlantic Monthly. An editor at a publishing house encouraged her to write a book about the sea for the general public. So she did. Her first book, "Under the Sea Wind," was published in nineteen forty-one. VOICE ONE:In nineteen forty-eight, Miz Carson began working on another book, "The Sea Around Us." It became her first best-selling book.Rachel Carson always researched carefully when she wrote. She gathered information from more than one thousand places to write "The Sea Around Us." She also wrote letters to experts all over the world."The Sea Around Us" was published in nineteen fifty-one. It was number one on the best-seller list for more than a year. It won the National Book Award. "The Sea Around Us" made Rachel Carson famous. The money the book earned eased her financial responsibilities for the first time in years.In nineteen fifty-two, Miz Carson was able to leave her job at the Fish and Wildlife Service and spend her time writing. Miz Carson moved to a home on the coast of Maine. There she studied the ecology of the sea. Her next book, "The Edge of the Sea," was published in nineteen fifty-five. It told of the connection of all living creatures in areas where land and ocean meet.(MUSIC)VOICE TWO:Rachel Carson's most famous book, "Silent Spring" was published in nineteen sixty-two. The idea for the book developed from a suggestion from a friend. Rachel's friend owned a protected area for birds. An airplane had flown over the area where the birds were kept and sp a powerful chemical called DDT. It was part of a project to control mosquitoes. Many songbirds and harmless insects were killed by the DDT. Miz Carson and other scientists were very concerned about the harmful effects of DDT and other insect-killing chemicals called pesticides. After World War Two, these poisonous chemicals were widely used to control insects. Pesticides were sprayed almost everywhere including agricultural fields and communities. DDT and other pesticides had become popular with the public and the government because they were so effective. Manufacturing these chemicals had become a huge industry.VOICE ONE:Rachel Carson tried to get many magazines interested in publishing a report about the subject. However, none would agree to publish anything about such a disputed subject. They said no one wanted to hear that industrial companies could cause great ecological damage.Miz Carson believed the public needed to know about this important issue. She decided to write a book about it. She collected facts from experts from all over the world. She gathered studies that showed the harmful effects of DDT, including declining bird populations and increased human cancers.In her book "Silent Spring," Miz Carson questioned the right of industrial companies to pollute without considering the effects on the environment. Miz Carson argued that this kind of pollution would result in ever-decreasing populations of birds and other wildlife. She said this would lead to the loss of the wonderful sounds of nature. The chemical poisoning of the environment, she said, would cause a silent spring.VOICE TWO:The chemical industry felt threatened. Industry spokesmen and other critics said the book was non-scientific and emotional. They misunderstood the message of the book. Miz Carson did not suggest that all pesticides be banned. She urged that control of these substances be given to biologists who could make informed decisions about the risks involved.Support for the book increased. By the end of nineteen sixty-two, there were more than forty bills in state legislatures proposing to control pesticides. Finally, in November, nineteen sixty-nine, the ed States government ruled that the use of DDT must stop in two years.Rachel Carson did not live to see how her book influenced the government's decision to ban DDT. She died of breast cancer in nineteen sixty-four. She was fifty-six years old.VOICE ONE:Two memorials honor Rachel Carson. One is the Rachel Carson National Wildlife Refuge in Maine. The other is the Rachel Carson Homestead in Springdale, Pennsylvania, the home she lived in when she was a child. Education programs are offered there that teach children and adults about her environmental values. Rachel Carson's voice is alive in her writings that express the wonder and beauty of the natural world. And her worldwide influence continues through the activities of the environmental protection movement she started.(MUSIC)ANNOUNCER: This Special English program was written by Lawan Davis. It was produced by Paul Thompson. Your announcers were Steve Ember and Rich Kleinfeldt. I'm Faith Lapidus. Join us again next week for another People in America program on the Voice of America.

Being a kid, and still believing that Cynthia was moving the cursor, I asked it if it was going to try to hurt us, the cursor went to 'no'. (Breath of relief here) Then I was going to ask another question. The cursor just shot to "good-bye". And it was over. At this point, Cynthia and I put our homemade Ouija board in a box, put that box in her dad’s closet and piled shoes on top of it, closed the closet door, and then the bedroom door, and locked it, and went to the living room to watch T.V. It was sometime around 12:45am and 1:30am.  Since Cynthia only visited her dad on the weekends, her bed was the hide-a-bed sofa couch in the living room. We turned on the T.V. to some movie that was on cable and settled down to go to sleep. About 20 minutes later, the T.V. turned off, and so did the lamp on the end table next to the couch on my side. I look at Cynthia and asked if she had turned on the sleep timer for the T.V. She said no and just turned the T.V. back on. I turned the lamp back on. About another 10 minutes went by and the television and the lamp both turned off again, at exactly the same time. Nothing else was turning off, just the T.V. and the lamp.

He laid waste the land of the Ammonites and went to Rabbah and besieged it, but David remained in Jerusalem. Joab attacked Rabbah and left it in ruins. 2David took the crown from the head of their king -its weight was found to be a talent of gold, and it was set with precious stones-and it was placed on David's head. He took a great quantity of plunder from the city 3and brought out the people who were there, consigning them to labor with saws and with iron picks and axes. David did this to all the Ammonite towns. Then David and his entire army returned to Jerusalem. 4In the course of time, war broke out with the Philistines, at Gezer. At that time Sibbecai the Hushathite killed Sippai, one of the descendants of the Rephaites, and the Philistines were subjugated. 5In another battle with the Philistines, Elhanan son of Jair killed Lahmi the brother of Goliath the Gittite, who had a spear with a shaft like a weaver's rod. 6In still another battle, which took place at Gath, there was a huge man with six fingers on each hand and six toes on each foot-twenty-four in all. He also was descended from Rapha. 7When he taunted Israel, Jonathan son of Shimea, David's brother, killed him. 8These were descendants of Rapha in Gath, and they fell at the hands of David and his men.

The Dormouse shook its head impatiently, and said, without opening its eyes, `Of course, of course; just what I was going to remark myself.' `Have you guessed the riddle yet?' the Hatter said, turning to Alice again. `No, I give it up,' Alice replied: `what's the answer?' `I haven't the slightest idea,' said the Hatter. `Nor I,' said the March Hare. Alice sighed wearily. `I think you might do something better with the time,' she said, `than waste it in asking riddles that have no answers.' `If you knew Time as well as I do,' said the Hatter, `you wouldn't talk about wasting IT. It's HIM.' `I don't know what you mean,' said Alice.浙江杭州牙齿美白价格

浙江牙科医院口腔修复口腔正畸怎么样好吗浙江牙齿正畸矫正什么价格I think fish are the most interesting creatures on the planet. They are absolutely fascinating. I love their different shapes, colours, social behaviour, everything. I can watch tropical fish in my aquarium for hours. Even the tiny little fish are so beautiful. When I go to the city aquarium, I can spend the whole morning or afternoon looking at the fish. I don’t have a favourite fish. I must confess that after watching the movie ‘Finding Nemo’ I do now like clownfish. As well as looking at fish, I also love eating them. Tuna is my favourite, especially raw tuna. When I visit Japan, the first thing I do is go to a sushi restaurant. Raw fish is so much tastier than cooked fish. And probably a lot healthier. Article/201104/132773PART THREE - A YOUNG WOMAN AT THORNFIELDCHAPTER SEVENMr. RochesterThe house where I was to work was called Thornfield. It was a large house in the country. After a day's journey, I arrived at the house. Mrs. Fairfax, who came out to meet me, was a little old lady. She seemed happy to have someone to talk to. The house was dark and cold, with large rooms full of beautiful, expensive [-----1-----]. It was not a very comforting house. But I was excited to live there, working for kind Mrs. Fairfax.However, I soon discovered Mrs. Fairfax was not the house's owner, as I had thought. She was only a servant. Thornfield belonged to a man named Mr. Rochester, who was not at home when I arrived. My pupil was a girl named Adele, who was seven or eight years old. Mr. Rochester had taken Adele to live with him, after her mother had died. She was French, and could not speak English. But I had learned French at Lowood, so I could speak to Adele. She was a pretty, happy child who liked o play with [-----2-----] and toys. I taught her English and other subjects for two hours every day in the library. I t was difficult to make her study, because she had never had school lessons before.A little time passed, and Mr. Rochester still had not come home. One day I decided to ask Mrs. Fairfax some questions about him. I was very [-----3-----] to know what kind of man he was, and Mrs. Fairfax was happy to talk.Vocabulary Focuscomforting: comfort的现在分词作形容词,使人舒适的,相当于comfortable.填空 :1.furniture2.dolls3.curiousArticle/200904/66599杭州治疗义齿多少钱#39;Don#39;t be afraid,#39;she said. #39; We#39;ve had some of your plums. We thought that it wasn#39;t stealing, but now I#39;m not so sure. So that was some money to pay for them. #39;;别怕,;她说,;我们吃了你的一些李子。我们起初觉得这不是偷,可现在我也不敢那么肯定。所以那是付给你的些李子钱。;The little man sat there on the ground and looked up into the sky. #39;Talking birds! Children with wings! This is a lesson for me. From now on,I#39;m going to live a better life,#39;he said. And he went into the house and was very kind to his wife.那个胖子坐在那儿地上,仰望着天空。;会说话的鸟!长翅膀的孩子!这对我可是一课。从今以后,我要过得好点儿,;他说。他进房里去,对他的妻子很和蔼。Plums are very nice, of course, but you soon feel hungry again. So the children stopped first at one house,then another, to ask for something to eat. They didn#39;t get anything because everyone was afraid of them and screamed and ran away when they saw them. By four o#39;clock they were getting very tired and hungry,so they flew down onto the roof of a church,to think what to do.李子当然很好吃,可很快你就又饿了,所以孩子们在一幢又一幢房子前停下来,想要些东西吃。他们什么也没得到,因为所有的人见到他们时都很害怕,尖叫着跑开了。到4点时他们变得又累又饿,于是就飞落在教堂的屋顶上,想想怎么办。#39; We can#39;t possibly fly all the way home without something to eat,#39; said Robert.;我们要是没有东西吃,就不可能飞回家去。;罗伯特说。In the end they decided to take some food from the vicar#39;s house next to the church.最后他们决定从紧挨着教堂的牧师家里拿些食物。#39; He#39;s a good man . He#39;ll understand. We#39;ll leave some money for the food,#39; Cyril said,#39;and a note saying that we#39;re sorry. #39;;他是好人。他会理解的。我们留些食品钱,;西里尔说,;再留张便条说我们很抱歉。;Cyril got in through the window and gave the food to the others, who were outside. There was some cold meat, half a cold chicken, some b and a bottle of soda-water. Then they all flew back up onto the church roof to eat it. They were very hungry, so they really enjoyed it. But when you are very hungry, and then you eat a big meal and sit in the hot sun on a roof, it is very easy to fall asleep. And so they did; while the sun slowly went down in the west.西里尔从窗子进去,把食物拿给在外边的其他孩子。有些冷肉、半只冷鸡、一些面包和一瓶汽水。然后他们全飞回到教堂房顶上吃起来。他们很饿,所以吃得很香。可是当你很饿的时候大吃了一顿、又在屋顶上晒着太阳时,那是很容易睡着的。他们就睡着了;;这时太阳慢慢地从西边落下去。They slept for a long time. When they woke up it was dark ;and,of course, they had no wings.他们睡了好长时间。他们醒来的时候天黑了;;当然了,他们也没有翅膀了。#39; We must get home,#39;Cyril said. #39; There#39;s a door over there. That#39;s the way down. #39;;我们得回家了。;西里尔说,;那儿有个门。那是下去的路。;But when they tried the door,they found that it was locked from the other side. They were on top of the church and they had no wings! How were they going to get down?可他们试着开门时才发现门是从另一面锁上的。他们在教堂顶上,又没有了翅膀!他们怎么下去呢? Article/201203/175458温州牙齿美白价格
