2、Citizen ScientistsUnderstanding how nature responds to climate change will require monitoring key life cycle event-flowering, the appearance of leaves, the first frog calls of the spring all around the world. But ecologists can\'t be everywhere so they\'re turning to non-scientists, sometimes called citizen scientists, forhelp. Climate scientists are not present everywhere. Because there are so many places in the world and not enough scientists to observe all of them, they\'re asking foryour help in observing signs of climate change across the world. The citizen scientist movement encourages ordinary people too observe a very specific research interest-birds, trees, flowers budding, etc. and send their observations to a giant database to be observed by professional scientists. This helps a small number of scientists track a large amount of data that they would never be able to gather on their own. Much like citizen journalists helping large publications cover a hyper-local beat, citizen scientists are ready forthe conditions where they live. All that\'s needed to become one is a few minutes each day oreach week to gather data and send it in. Agroupof scientists and educators launched an organization last year called the National Phenology Network. "Phenology" is what scientists call the study of the timing of events in nature. One of the group\'s first efforts relies on scientists and non-scientists alike to collect data about plant flowering and leafing every year. The program, called Project BudBurst, collects life cycle data on a variety of common plants from across the United States. People participating in the project which is open to everyone record their observations on the Project BudBurst website. "People don\'t have to be plant experts, they just have to look around and see what\'s in their neighborhood," says Jennifer Schwartz, an education consultant with the project. "As we collect this data, we\'ll be able to make an estimate of how plants and communities of plants and animals will respond as the climate changes. "What are citizen scientists asked to do?【单选题】
A.To develop a specific research interest and become professional scientists.
B.To send their research observations to a professional database.
C.To increase their knowledge about climate change.
D.To keep a record of their research observations.
正确答案:B
答案解析:根据send their observations to a giant database to be observed by professional scientists可知。
3、Science Fiction1 Amongst the most popular books being written today are those that are usually classified asscience fiction. Hundreds of titles are published every year and are read by all kinds of people. Furthermore, some of the most successful films of recent years have been based on science fiction stories. 2 It is often thought that science fiction is a fairly new development in literature, but its ancestors can be found in books written hundreds of years ago. These books were often concerned with the presentation of some forms of ideal society, a theme that is still often found in modern stories. 3 Most of the classics of science fiction, however, have been written within the last hundred years. Books by writers such as Jules Verve and H. G Wells, to mention just two well known authors, have been translated into many languages. 4 Modern science fiction writers don\'t write about men from Mars orspace adventure stories. They are more interested in predicting the results of technical developments on society and the human mind; orin imagining future worlds that are a reflection of the world that we live in now. Because of this their writing has obvious political undertones (涵义). 5 In an age where science fact frequently overtakes (超过) science fiction, the writers may find it difficult to keep ahead of scientific advances. Those who are sufficiently clear-sighted to see the way we are going, however, may provide a valuable lesson on how to deal with the problems which society will inevitably face as it tries to master its new technology. Paragraph 2____【单选题】
A.A Fairly New Development
B.Classics of Science Fiction
C.Difficulty in Keeping ahead of Scientific Advances
D.Origins of Science Fiction
E.Themes of Modern Science Fiction
F.SuccessfulFilms
正确答案:D
答案解析:第2段第1句说科幻小说常被认为是文学中较新的一种事物,但它的先驱可以在几百年以前写的书中找到。连词but在这里起转折作用。这一句的中心词是ancestors,与origin意思相似,根据这一线索,我们得知该段是在介绍科幻小说的起源,故选D。
4、Cloning: Future Perfect?1 A clone is an exact copy of a plant oranimal produced from any one cell. Since Scottish scientists reported that they had managed to clone a sheep named Dolly in 1997, research into cloning has grown rapidly. In May 1998, scientists in Massachusetts managed to create two identical calves using cloning technology. A mouse has also been cloned successfully. But the debate over cloning humans really started when Chicago physicist Richard Seed made a surprising announcement: "We will have managed to clone a human being within the next two years," he told the world. 2 Seed\'s announcement provoked a lot of media attention, most of it negative. In Europe, nineteen nations have already signed an agreement banning human cloning and in the US the President announced: "We will be introducing a law to ban human cloning and many states in the US will have passed anti-cloning laws by the end of the year". 3 Many researchers are not so negative about cloning. They are worried that laws banning human cloning will threaten important research. In March, The New England Journal of Medicine called any plan to ban research on cloning humans seriously mistaken. Many researchers also believe that in spite of attempts to ban it, human cloning will have become routine by 2010 because it is impossible to stop the progress of science. 4 Is there reason to fear that cloning will lead to a nightmare world? The public has been bombarded (轰炸) with newspaper articles, television shows and films, as well as cartoons. Such information is often misleading, and makes people wonder what on earth the scientists will be doing next. 5 Within the next five to ten years scientists will probably have found a way of cloning humans. It could be that pretty soon we will be able to choose the person that we want our child to look like. But how would it feel to be a clone among hundreds, the anti-cloners ask Pretty cool, answer the pro-cloners (赞成克隆的人). Within ten years scientists will probably have____. 【单选题】
A.the nucleus of a cell
B.cloned human beings
C.a human being in two years
D.a law to ban human cloning
E.a report on human cloning
F.heavy media coverage
正确答案:B
答案解析:文章最后一段提到未来5到10年内人们可能会找到克隆人的办法,即会有克隆人出现,故选B。
5、What Is the Coolest Gas in the Universe?What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was - 91℃, which occurred in Antarctica (南极洲) in 1983.We encounter an interesting situation when we discuss temperatures in space.Temperatures in Earth orbit actually range from about +120℃ to - 120℃. The temperature depends upon _____ you are in direct sunlight orshade. Obviously, -120℃ is colder than our body can safely endure. Thank NASA science forwell, de signed space suits that protect astronauts from these temperature extremes.The space temperatures just discussed affect only our areal of the solar system. Obviously, it is hotter closer to the Sun and colder as we travel away from the Sun. Astronomers estimate temperatures at Pluto are about - 210℃. How cold is the lowest estimated temperature in the entire universe? Again, it depends upon your location. We are taught it is supposedly impossible to have a temperature below absolute zero, which is - 273℃, at which atoms do not move. Two scientists, whose names are Cornell and Wieman, have successfully cooled down a gas to a temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 fortheir work, not a discovery, in this case.Why is the two scientists\' work so important to science?In the 1920s, Satyendra Nath Bose was studying an interesting theory about special light particles we now call photons (光子). Bose had trouble convincing other scientists to believe his theory, so he contacted Albert Einstein. Einstein\'s calculations helped him theorize that atoms would behave as Bose thought—but only at very cold temperatures.Scientists have also discovered that ultra - cold(超冷) atoms can help them make the world\'s atomic clocks even more accurate. These clocks are so accurate today they would only lose one second every six million years! Such accuracy will help us travel in space because distance is velocity times time 4 ( d = v×t). With the long distances involved in space travel, we need to know time as accurately as possible to get accurate distance.【单选题】
A.whether
B.where
C.what
D.when
正确答案:A
答案解析:本题难度不大,考查whether or的用法,答案干扰项干扰不大。可以先看选项得到信息提示。很明显,此处是whether or结构,是说“温度(的多少)取决于你是否在阳光下或阴影里”,答案是A。
