One key to unders

8、tanding how and by something happened is to discover when it happened.Radiocarbon dating was developed in the late 1940s by physicist Willard F. Libby at he University of Chicago. An atom of ordinary carbon，called carbon-12，has six protons（中子）and six neutrons（质子）in its nucleus. Carbon-14，or C-14，is

9、a radioactive，unstable form of carbon that has two extra neutrons（原子核）。 It returns to a more stable form of carbon through a process called decay（衰减）。 This process involves the loss of he extra neutrons and energy from the nucleus.In Libbys radiocarbon dating technique，the weak radioactive emissions

10、（放射）from his decay process are counted by instruments such as a radiation detector and counter. he decay rate is used to determine the proportion of C-14 atoms in the sample being dated.Carbon-14 is produced in the Earths atmosphere when nitrogen（氮）-14，or N-14，interacts with cosmic rays（宇宙射线）。 Scien

11、tists believe since the Earth was formed，the mount of nitrogen in the atmosphere has remained constant. Consequently，C-14 formation is thought to occur at a constant rate. Now the ratio of C-14 to other carbon toms in the atmosphere is known. Most scientists agree that this ratio is useful for datin

12、g items back to at least 50，000 years.All life on Earth is made of organic molecules（分子）that contain carbon atoms coming from the atmosphere. So all living things have about the same ratio of C-14 atoms to other carbon atoms in their tissues（组织）。 Once an organism（有机体）dies it tops taking in carbon in

13、 any form，and the C-14 already present begins to decay. Over time the amount of C-14 in the material decreases，and the ratio of C-14 to other carbon toms goes down. In terms of radiocarbon dating，the fewer C-14 atoms in a sample，the older that sample is.16 Nowadays many scientists depend on radiocar

17、zees living in the wild. But this is more than an environmental or moral tragedy（悲剧）。 Chimpanzee extinction may also have profound implications（含意）for the survival of their distant relatives - human beings.2 In 1975 the biologist Marie-Claire King and Allan Wilson discovered that the human and chimp

18、anzee genomes（基因组）match by over 98%. Compare this to the mouse，used as model for human disease in lab tests，which shares only 60% of its DNA with us. In fact，chimpanzees are far more similar to humans than they are to any other species of monkey. As well as resembling us genetically，chimps are highl

19、y intelligent and able to use tools. These facts alone should be enough to make protection of chimps an urgent priority（优先）。 But there is another，more selfish reason to preserve the chimp.3 The chimpanzees trump card（王牌）comes in the field of medical research. Chimpanzees are so similar to humans tha

20、t veterinarians（兽医）often refer to human medical textbooks when treating them. Yet chimpanzees do show differences in several key areas. In particular，chimps are much more resistant to a number of major diseases. It is this ability that is so interesting.4 For example，chimps seem to show a much highe

21、r resistance than humans to HIV，the virus that causes AIDS. Indeed，their use as experimental animals in AIDS research has declined because they are so resistant.5 By sequencing the chimp genome and pinpointing（找到）the place where the chimpanzee DNA sequence differs from that of humans，scientists hope

22、 to be able to discover which part of the genetic code gives chimps their increased resistance to some diseases. This，they hope，will allow them to develop new and more effective treatments for the human forms of these diseases. Such treatments could include the production of new drugs or even the al

23、teration（变化）of the human genetic sequence. The recently completed human genome sequencing project has shown that such an effort is now well within our reach.23 Paragraph 124 Paragraph 225 Paragraph 326 Paragraph 4A Reasons for HIV resistanceB Implications of chimpanzee extinction for humansC Effecti

26、constituent（构成成分）of the biosphere（生物圈）is liquid water. This can only exist in a very narrow range of temperatures，since water freezes at 0 and boils at 100。 Life as we know it would only be possible on the surface of a planet which had temperatures somewhere within this narrow range.The earths suppl

27、y of water probably remains fairly constant in quantity. The total quantity of water is not known very accurately，but it is about enough to cover the surface of the globe to a depth of about two and three-quarter kilometers. Most of it is in the form of the salt water of the oceans - about 97 per ce

28、nt. The rest is fresh，but three-quarters of this is in the form of ice at the Poles and on mountains，and cannot be used by living systems until melted. Of the remaining fractional which is somewhat less than one per cent of the whole，there is 10-20 times as much stored underground water as there is

29、actually on the surface. There is also a tiny，but extremely important fraction of the water supply which is present as water vapor in the atmosphere.Water vapor in the atmosphere is the channel through which the whole water circulation（循环）of the biosphere has to pass. Water evaporated（蒸发）from the su

30、rface of the oceans，from lakes and rivers and from moist（潮湿旳）earth is added to it. From it the water comes out again as rain or snow，falling on either the sea or the land. There is，as might be expected，a more intensive evaporation per unit area over the sea and oceans than over the land，but there is

31、 more rainfall over the land than over the oceans，and the balance is restored by the runoff from the land in the form of rivers.31 Liquid water only existsA in the center of the earth.B on the surface of our planet.C in a very narrow range of temperatures.D in the coastal areas of the earth.32 The t

33、.D comes from the rain.34 The word “fraction” in the second paragraph meansA a very small amount.B a large area.C an important system.D a major source of information35 There is more of rainfallA over the mountains than over the rivers.B over the rivers than over the mountainsC over the oceans than o

34、ver the land.D over the land than over the oceans.第二篇 Mind-reading MachineA team of researchers in California has developed a way to predict what kinds of objects people are looking at by scanning（扫描）whats happening in their brains.When you look at something，your eyes send a signal about that object

35、 to your brain. Different regions of the brain process the information your eyes send. Cells in your brain called neurons（神经元）are responsible for this processing.The fMRI（functional Magnetic Resonance Imaging）（功能性磁振造影）brain scans could generally match electrical activity in the brain to the basic sh

36、ape of a picture that someone was looking at.Like cells anywhere else in your body，active neurons use oxygen. Blood brings oxygen to the neurons，and the more active a neuron is，the more oxygen it will consume. The more active a region of the brain，the more active its neurons，and in turn，the more blo

37、od will travel to that region. And by using fMRI，scientists can visualize（使显现）which parts of the brain receive more oxygen-rich blood - and therefore，which parts are working to process information.An fMRI machine is a device that scans the brain and measures changes in blood flow to the brain. The t

38、echnology shows researchers how brain activity changes when a person thinks，looks at something，or carries out an activity like speaking or reading. By highlighting the areas of the brain at work when a person looks at different images，fMRI may help scientists determine specific patterns of brain act

39、ivity associated with different kinds of images.The California researchers tested brain activity by having two volunteers view hundreds of pictures of everyday objects，like people，animals，and fruits. The scientists used an fMRI machine to record the volunteers brain activity with each photograph the

40、y looked at. Different objects caused different regions of the volunteers brains to light up on the scan，indicating activity. The scientists used this information to build a model to predict how the brain might respond to any image the eyes see.In a second test，the scientists asked the volunteers to

41、 look at 120 new pictures. Like before，their brains were scanned every time they looked at a new image. This time，the scientists used their model to match the fMRI scans to the image. For example，if a scan in the second test showed the same pattern of brain activity that was strongly related to pict

42、ures of apples in the first test，their model would have predicted the volunteers were looking at apples.36 What is responsible for processing the information sent by your eyes？A The magnetic system in the brain.B The central part of the heart.C Oxygen-rich blood.D Neurons in the brain.37 The functio

43、n of an fMRI machine isA to show how neutrons take in oxygen-rich blood.B to measure how dense the blood is in the brain.C to record how much oxygen the brain consumes.D to identify which parts of the brain are processing information38 The expression “highlighting the areas of the brain at work in p

44、aragraph 5 meansA giving light to the parts of the brain that are processing information.B marking the parts of the brain that are processing information.C putting the parts of the brain to work.D preventing the parts of the brain from working.39 The researchers experimented onA animals and objects.

45、B fMRI machines.C two volunteers.D thousands of pictures.40 Which of the following can best replace the title of the passage？A Recent Development in Science and Technology.B Your Thoughts Can Be Scanned.C A Technological Dream.D An Intelligent Robot.第三篇 Youth Emancipation in SpainThe Spanish Governm

46、ent is so worried about the number of young adults still living with their parents that it has decided to help them leave the nest.Around 55 percent of people aged 18-34 in Spain still sleep in their parents homes，says the latest report from the countrys state-run Institute of Youth.To coax（劝诱）young

47、 people from their homes，the Institute started a “Youth Emancipation（解放）“ program this month. The program offers guidance in finding rooms and jobs.Economists blame young peoples family dependence on the precarious（不稳定旳）labor market and increasing housing prices. Housing prices have risen 17 percent

48、 a year since .Cultural reasons also contribute to the problem，say sociologists（社会学家）。 Family ties in south Europe - Italy，Portugal and Greece - are stronger than those in middle and north Europe，said Spanish sociologist Almudena Moreno Minguez in her report “The Late Emancipation of Spanish Youth：

49、Key for Understanding”。“In general，young people in Spain firmly believe in the family as the main body around which their private life is organized，” said Minguez.In Spain - especially in the countryside，it is not uncommon to find entire groups of aunts，uncles，cousins，nieces and nephews（外侄/侄子）all li

50、ving on the same street. They regularly get together for Sunday dinner.Parents tolerance is another factor. Spanish parents accept late-night partying and are wary of setting bedtime rules.“A child can arrive home at whatever time he wants. If parents complain hell put up a fight and call the father

51、 a fascist，” said Jose Antonio G6mez Yanez，a sociologist at Carlos III University in Madrid.Mothers willingness to do childrens household chores（家务）worsens the problem. Dionisio Masso，a 60-year-old in Madrid，has three children in their 20s. The eldest，28，has a girlfriend and a job. But life with mum

52、 is good.“His mum does the wash and cooks for him； in the end，he lives well，” Masso said.41 The “Youth Emancipation” program aims at helping young peopleA fight for freedom.B live in an independent way.C fight against social injustice.D get rid of family responsibilities.42 It can be inferred from p
