 The United States government wants to know what the public thinks about its findings on the safety of cloned animals.

  The Food and Drug Administration says meat and milk from clones of adult cattle,pigs and goats are safe to eat. An F. D. A. official called them "as safe to eat as the food we eat every day. " And when those clones reproduce sexually,the agency says,their offspring (后代) are safe to eat as well. But research on cloned sheep is limited. So the F. D. A. proposes that sheep clones not be used for human food.

  The United States this year could become the first country to approve the sale of foods from cloned animals. First,however,the public will have ninety days to comment on three proposed documents. On December 28th the F. D. A. released a long report,called a draft risk assess?ment,along with two policy documents.

  The agency says it must receive comments by April second. The F. D. A. seemed ready to act several years ago,but an advisory committee called for more research.

  For now,the government will continue to ask producers to honor a request that they not sell foods from cloned animals.

  Clones are still rare. They cost a lot and are difficult to produce.

  The F. D. A. says most food from cloning is expected to come not from clones themselves,but from their sexually reproduced offspring. It says clones are expected to be used mostly as breeding animals to spread good qualities.

  Public opinion studies show most Americans do not like the idea of food from cloned ani?mals. But this research also shows the public knows little about cloning.

  Cloning differs from genetic engineering. A cell taken from a socalled donor animals is grown into an embryo (胚胎) in the laboratory. Next,the embryo is placed into the uterus (子宮) of a female animal. If the process is successful,the pregnancy reaches full term and a genetic copy of the donor animal is born.

(   ) 1. From the passage we know that         .

   A. foods from cloned animals are popular in America

   B. cloned adult animals are safe to eat except sheep

   C. cloned animals will be easy to produce

   D. most foods from cloning are expected to take place of other foods

(   ) 2. The main purpose of the text is to         .

   A. tell an interesting story   B. give some advice on foods

   C. give a report   D. compare different opinions

(   ) 3. Who believes that foods from cloning are safe to eat?

   A. Most Americans. B. An advisory committee.

   C. Critics. D. The F. D. A.

(   ) 4. It can be inferred from the last paragraph that         .

   A. cloning has much in common with genetic

   B. not every cell taken from a donor animal can grow into a genetic copy

   C. the donor animal should be a female one

   D. cloned animals grow faster than normal ones

 We know the famous ones―the Thomas Edisons and the Alexander Graham Bells,but what about the less famous inventors? What about the people who invented the traffic light and the windshield wiper (雨刮器) ? Shouldn't we know who they are?

  Joan McLean thinks so. In fact,McLean,a professor of physics at Mountain University in Range,feels so strongly about this matter that she's developed a course on the topic. In addition to learning "who" invented "what"，McLean also likes her students to learn the answers to the "why" and "how" questions. According to McLean, "When students learn the answers to these questions,they are better prepared to recognize opportunities for inventing and more motivated to give inventing a try,"

  Her students agree. One young man with a patent for an unbreakable umbrella is walking proof of McLean's statement. "If I had not heard the story of the windshield wiper's inven?tion ,"said Tommy Lee,a senior physics major, "I would never have dreamed of turning my bad experience during a rainstorm into something so constructive. " Lee is currently negotiating to sell his patent to an umbrella producer.

  So,just what is the story behind the windshield wiper? Well,Mary Anderson came up with the idea in 1902 after a visit to New York City. The day was cold and stormy,but Anderson still wanted to see the sights,so she jumped aboard a streetcar. Noticing that the driver was struggling to see through the snow covering the windshield,she found herself wondering why there couldn't be a builtin device for cleaning the window. Still wondering about this when she returned home to Birmingham,Alabama,Anderson started drafting out solutions. One of her ideas,a lever (操作桿) on the inside of a vehicle that would control an arm on the outside,became the first windshield wiper.

  Today we benefit from countless inventions and innovations. It's hard to imagine driving without Garrett A. Morgan's traffic light. It's equally impossible to picture a world without Katherine J. Blodgett's innovation that makes glass invisible. Can you picture life without clear windows and eyeglasses?

(   ) 1. By mentioning "traffic light" and " windshield wiper" , the author indicates that countless inventions are         .

   A. beneficial,because their inventors are famous

   B. beneficial,though their inventors are less famous

   C. not useful,because their inventors are less famous

   D. not useful,though their inventors are famous

(   ) 2. Professor Joan McLean's course aims to .

   A. add colour and variety to students' campus life

   B. inform students of the windshield wiper's invention

   C. carry out the requirements by Mountain University

   D. prepare students to try their own inventions

(   ) 3. Tommy Lee's invention of the unbreakable umbrella was         .

   A. not eventually accepted by the umbrella producer

   B. inspired by the story behind the windshield wiper

   C. due to his dream of being caught in a rainstorm

   D. not related to Professor Joan McLean's lectures

(   ) 4. Which of the following can best serve as the title of this passage?

   A. How to Help Students to Sell Their Inventions to Producers?

   B. How to Design a Builtin Device for Cleaning the Window?

   C. Shouldn't We Know Who Invented the Windshield Wiper?

   D. Shouldn't We Develop Invention Courses in Universities?

  They will soon fast track a new resort at Inuvik,on the Arctic Ocean. It will be extremely popular,mainly because it will be the only beach resort left where people can enjoy a nice cool swim. A six lane (車道) highway will be built so people from across North America can easily access the resort with their SUV's and Winnebagos.

  By 2010 parts of the southern States will be abandoned due to the heat and the extreme weather. So,the parts of Las Vegas that can be moved will be moved to Inuvik,along with a bunch of shopping malls.

  Immediately next to the beach will be a huge iceberg,made out of white plastic. Penguins and pandas,by popular demand,will be placed on the top; elephants and giraffes will be imported to run around on a platform at the base of the iceberg. Unfortunately the plastic,of course,will soon damage the feet of the animals,so they will all have to wear pink booties. So,as all the animals proudly walk around in their booties,all the Americans will agree that,although Inuvik isn't a Disneyland or a Las Vegas,it certainly is a nice cool place.

  In 2010,most of the people in the southern United States will escape the fires,heat,hurricanes,tornados,snow,and flooding by heading north to the Arctic Ocean where they will settle in the resort city of Inuvik. This location not only has a cool ocean to swim in,but at the end of the beach there are two real trees to enjoy. Those trees will look strong and healthy,because they will be nourished and protected by a team of 140 dedicated workers,24 hours a day.

  In late June,tourists in Inuvik will love to enjoy themselves for 20 hours a day in real sunshine (which will be mostly smog free,as long as the wind blows from the north) . In the winter,Inuvik will be even busier. It will attract people from around the globe who want to adapt to global warming by escaping.

  The escape will last all night long,and in Inuvik in December,that means the party goes on for 24 hours. At the end of the night,as the party comes to an end,everyone will have a chance to pause and relax,then they can plunge into the next night's party. Inuvik will be the most popular resort on the planet.

(   ) 1. Why will Inuvik become an extremely popular resort in 2010,according to the passage?

   A. Tourists can enjoy themselves together with some animals.

   B. People can enjoy a nice cool summer in Inuvik.

   C. Las Vegas will have been moved to Inuvik.

   D. Almost all the highways are built for people to go there.

(   ) 2. What do you know about the huge iceberg next to the beach of Inuvik?

   A. It is just the iceberg that caused the sinking of Titanic.

   B. It will be made up of many small icebergs on the Arctic Ocean.

   C. Another Disneyland may be set up on the huge iceberg.

   D. The manmade iceberg will attract many tourists from around the globe.

(   ) 3. In 2010,people in the southern United States will         .

   A. have to struggle against many natural disasters as well as the slavery

   B. make a living by raising penguins and whales

   C. head north to the Arctic Ocean and settle there

   D. try to prevent themselves from the sunshine

(   ) 4. Which of the following is true?

   A. In winter,Inuvik,the new resort will be quite silent.

   B. Inuvik may be a movable resort in 2010.

   C. Inuvik attract tourists from the globe not only in summer but also in winter.

   D. There will be no Inuit in Inuvik in 2010.
