Computer Virus

  The computer virus is an outcome of the computer overgrowth in the 1980s.The cause of the term "computer virus" is the likeness between the biological virus and the evil program infected with computers. The origin of this term came from an American science fiction〝The Adolescence of P-1〞written by Thomas J·Ryan, published in 1977.Human viruses invade a living cell and turn it into a factory for manufacturing viruses. However, computer viruses are small programs. They replicate by attaching a copy of themselves to another program.
  Once attached to host Program, the viruses then look for other programs to "infect". In this way, the virus can spread quickly throughout a hard disk or an entire organization when it infects a LAN or a multi-user system. At some point, determined by how the virus was programmed the virus attacks. The timing of the attack can be linked to a number of situations, including a certain time or date, the presence of a particular file, the security privilege level of the user, and the number of times a file is used. Likewise, the mode of attack varies. So-called "benign" viruses might simply display a message, like the one that infected IBM's main computer system last Christmas with a season's greeting. Malignant viruses are designed to damage the system. The attack is to wipe out data, to delete flies or to format the hard disk.
  What Kind of Viruses Are There? There are four main types of viruses: shell, intrusive, operating system and source ode. Shell viruses wrap themselves around a host program and don't modify the original program. Shell programs are easy to write, which is why about half of viruses are of this type. Intrusive viruses Invade an existing program and actually insert a portion of themselves into the host program. Intrusive viruses are hard to write and very difficult to remove without damaging the host file.
  16 The term "computer virus" came from an American science fiction "The Adolescence of P-1"
  A Right       B Wrong       C Not mentioned
  17 The virus that infected IBM's main computer system last Christmas was designed to damage the system
  A Right       B Wrong       C Not mentioned
  18 There are two kinds of attack modes
  A Right       B Wrong       C Not mentioned
  19 If the development of computers was controlled there will be no computer virus.
  A Right       B Wrong       C Not mentioned
  20 Computer virus spread more quickly when it infects a LAN than a multi-user system
  A Right       B Wrong       C Not mentioned
  21 Four main types of viruses are illustrated in detail.
  A Right       B Wrong       C Not mentioned
  22 You have to damage the host file if you want to remove Intrusive virus.

Telepathy-mind to mind contact

  1 Telepathy is the ability to communicate without the use of the five senses(sight, hearing, touch, smell, taste).It is an instinct, and although quite dormant in many of us, we are often capable of tapping into our latent abilities in times of emergency or need.
  2 Where this instinct lies is uncertain.Some say that it is located in the huge area of our brains that are wholly unused, whereas others argue that instinct existed before the brain evolved and must therefore lie else-where in the body.
  3 When we intuitively know that something is happening, or about to happen, our instinct has kicked in.We are drawing upon resources within the unconscious mind. When the resources of two unconscious minds link together into the same frequency, we call it Telepathy.
  4 Telepathy can be either projective or perceptive, we either send or receive. If you know who is calling before you answer the ringing phone, you are probably a good receiver.If you think of a person, and they call you, you are most likely better at sending.
  5 You can easily put your abilities to the test.Think of somebody and will them to contact you.Be patient, the other person may not be a good receiver, but they should contact you much earlier than would normally be expected.Or whenever the phone rings, try "feeling" who's contacting you.Don't guess, try to feel the vibrations.However, if neither of these work for you, that doesn't mean that you are not capable of telepathy.As mentioned earlier, telepathy is most likely to kick in under circumstances of emergency.
  6 Telepathic Dreams. Dreams often contain telepathic messages.Two people may both dream of the other, and find that their dreams had a distinct connection.These people are probably mutually linking to the unconscious mind.A projection of the mind——a form of astral projection?
  7 Telepathy&Relationships The more people spend time together, the more likely they are to be able to link up to the others mind, especially when separated.There are two reasons for this.One is that they understand the others, mind through time spent together;the other is that there is usually a strong desire to communicate.
  23 Paragraph 3 _____.
  24 Paragraph 4 _____.
  25 Paragraph 5 _____.
  26 Paragraph 6 _____.
  A Telepathy is very common in our life.
  B how does Telepathy formed
  C you can test telepathy in daily life
  D Telepathy can be sent or received
  E Relationships affected Telepathy
  F Telepathic Dreams
  27 Telepathy is the ability _____.
  28 Telepathy is formed _____.
  29 you are a good Telepathy receiver _____.
  30 two close friends are more likely to have Telepathy _____.
  A when separated
  B when they both dream of the other
  C when our instinct and resources within the unconscious mind link together
  D only some people have
  E to communicate without the use of the five senses
  F If you know who is calling before you answer the ringing phone
 
  第4部分:阅读理解(第31~45题,每题3分,共45分)
  下面有3篇短文,每篇短文后有5道题,每题材后面有4个选项。请仔细阅读短文并根据短文回答其后面的问题,从4个选项中选择一个最佳答案涂在答题卡相应的位置上。
  第一篇

Intelligence

  Are some people born clever,and others born stupid? Or is intelligence developed by our environment and our experience? Strangely enough, the answer to these questions is yes. To some extent our intelligence is given to us at birth, and no amount of education can make a genius out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. Thus the limits of person's intelligence are fixed at birth, whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways.
  It is easy to show that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be intelligent. Thus if we take two unrelated people at random from population, it is likely that their degree of intelligence will be completely different. If, on the other hand, we take two identical twins, they will very likely to be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth.
  Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this indicates that environment as well as birth plays a part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all are likely to have similar degree of intelligence.
  31 The writer is in favor of the view that man's intelligence is given to him _____.
  A at birth
  B through education
  C both at birth and through education
  D neither at birth nor through education
  32 If a child is born with low intelligence, he can _____.
  A become a genius
  B still become a genius if he should be given special education
  C reach his intelligence limits in rich surroundings
  D not reach his intelligence in his life
  33 In the second paragraph, the underlined sentence means "if we _____."
  A pick any two persons
  B take out two different persons
  C choose two persons who are relative
  D choose two persons with different intelligence
  34 The example of the twins going to a university and to a factory separately shows _____.
  A the importance of their intelligence
  B environment influences
  C the importance of their positions
  D the part that birth plays
  35 which is true according to the passage?
  A Environment plays a more important role than birth
  B two identical twins have the same intelligence no matter where they are
  C two unrelated persons is more likely to have different intelligence
  D Education has no effect on low intelligence person
  第二篇

Hair Detectives

  Scientists have found a way to use hair to figure out where a person is from and where that person has been. The finding could help solve crimes, among other useful applications.
  Water is central to the new technique. Our bodies break water down into its parts: hydrogen and oxygen. Atoms of these two elements end up in our tissues and hair.
  But not all water is the same. Hydrogen and oxygen atoms can vary in how much they weigh. Different forms of a single element are called isotopes. And depending on where you live, tap Water contains unique proportions of the heavier and lighter isotopes of hydrogen and oxygen.
  Might hair record these watery quirks? That's what James R. Ehleringer, an environmental scientist at the University of Utah in Salt Lake City, wondered.
  To find out, he and his colleagues collected hair from barbers and hair stylists in 65 cities in 18 states across the United States. The researchers assumed that the hair they collected came from people who lived in the area.
  Even though people drink a lot of bottled water these days, the scientists found that hair overwhelmingly reflected the concentrations of hydrogen and oxygen isotopes in local tap water. That's probably because people usually cook their food in the local water. What's more, most of the other liquids people drink including milk and soft drinks contain large amounts of water that also come from sources within their region.
  Scientists already knew how the composition of water varies throughout the country. Ehleringer and colleagues combined that information with their results to predict the composition of hair in people from different regions. One hair sample used in Ehleringer's study came from a man who had recently moved from Beijing, China, to Salt Lake City. As his hair grew, it reflected his change in location.
  The new technique can't point to exactly where a person is from, because similar types of water appear in different regions that span a broad area. But authorities can now use the information to analyze hair samples from criminals or crime victims and narrow their search for clues.
  36 Which of the following about tap water is NOT correct?
  A Tap water reflects the concentrations of hydrogen and oxygen isotopes in different regions.
  B Tap water contains unique proportions of isotopes of hydrogen and oxygen.
  C Tap water is a kind of soft drink in the United States
  D Tap water is used to cook food.
  37. James R. Ehleringer tried to find out
  A if tap water contains unique proportions of isotopes of hydrogen and oxygen.
  B if it is possible to collect hair samples across the country.
  C if our bodies break water down into its parts……
  D if the composition of hair can indicate exactly where people are from.
  38. Which of the following statements is meant by the writer?
  A Ehleringer's research proved successful in China
  B Ehleringer failed in his research.
  C Ehleringer can be a successful detective.
  D Ehleringer was successful in his research.
  39. What can we know from the last paragraph?
  A  The new technique can tell precisely where a person lives.
  B Water supplied in different regions all come from the same source.
  C Types of water used in different regions provide useful information for the police.
  D Hair samples provide the most important clues to identify crimes.
  40. Which of the following is closest in meaning to the title?
  A Human hair may help detectives to solve crimes.
  B Animal hair may help detectives to solve crimes.
  C Human hair's features……
  D Most detectives are hair specialists.

Plant Gas

  Scientists have been studying natural sources of methane for decades but hadn't regarded plants as a producer, notes Frank Keppler, a geochemist at the Max Planck Institute for Nuclear Physics in Heldelberg, Germany. Now Keppler and his colleagues find that plants, from grasses to trees, may also be sources of the greenhouse gas. This is really surprising, because most scientists assumed that methane production requires an oxygen-free environment.
  Previously, researchers had thought that it was impossible for plants to make significant amounts of the gas. They had assumed that microbes2 need to be in environments without oxygen to produce methane. Methane is a greenhouse gas, like carbon dioxide. Gases such as methane and carbon dioxide trap heat in Earth's atmosphere and contribute to global warming.
  In its experiments, Keppler's team used sealed chambers that contained the same concentration of oxygen that Earth's atmosphere has. They measured the amounts of methane that were released by both living plants and dried plant material, such as fallen leaves.
  With the dried plants, the researchers took measurement at temperatures ranging from 30 degrees Celsius to 70 degrees C. At 30 degrees C, they found, a gram of dried plant material released up to 3 nanograms of methane per hour. (One nanogram is a billionth of a gram.) With every 10-degree rise in temperature, the amount of methane released each hour roughly doubled.
  Living plants growing at their normal temperatures released as much as 370 nanograms of methane per gram of plant tissue per hour. Methane emissions tripled when living and dead plant was exposed to sunlight.
  Because there was plenty of oxygen available, it's unlikely that the types of bacteria that normally make methane were involved. Experiments on plants that were grown in water rather than soil also resulted in methane emissions. That's another strong sign that the gas came from the plants and not soil microbes.
  The new finding is an "interesting observation," says Jennifer Y. King, a biogeochemist at the University of Minnesota in St. Paul3. Because some types of soil microbes consume methane, they may prevent plant-produced methane from reaching the atmosphere. Field tests will be needed to assess the plant's influence, she notes. (367 words)
  41 that was scientists' understanding of methane?
  A) It was produced from plants.
  B) It was not a greenhouse gas.
  C) It was produced in oxygen-free environments.
  D) It traps more heat than any other greenhouse gas.
  42 To test whether plants are a source of methane, the scientists created
  A) a oxygen-free environment.
  B) an environment with the same concentration of oxygen as the Earth has.
  C) a carbon dioxide-free environment.
  D) an environment filled with the greenhouse gas
  43 hich statement is true of the methane emissions of plants in the experiment?
  A) The lower the temperature, the higher the amount of methane emissions.
  B) Living plants release less methane than dried plants at the same temperature.
  C) When exposed to sunlight, plants stop releasing methane.
  D) The higher the temperature, the greater the amount of methane emissions.
  44 What of the following about methane is Not mentioned in the passage ?
  A) Plants growing in soil release methane.
  B) Plants growing in water release methane.
  C) Soil microbes consume methane.
  D) Microbes in plants produce methane.
  45 What is the beneficial point of some microbes consuming plant-produced methane?
  A) Methane becomes less poisonous.
  B) methane is turned into a fertilizer.
  C) Less methane reaches the atmosphere.
  D) Air becomes cleaner……

If you want to win in sports, wear red

  If winning is everything, British anthropologists have some advice: Wear red. Their survey of four sports at the 2004 Olympic Games in Athens shows competitors were more likely to win their contests if they wore red uniforms or red body armor.
  "Across a range of sports, we find that wearing red is consistently associated with a higher probability of winning," report Russell A. Hill and Robert A. Barton of the University of Durham in England. Their findings are in Thursday's issue of the journal Nature.
   _____(46). Often it is sexually selected so that scarlet markings signal male dominance.
  Just think of the red stripes on the scowling face of the male Mandrill, Africa's largest monkey species.      _____(47).It's the female black widow spider that is venomous and displays a menacing red dot on her abdomen.
  Similarly, the color's effect also may subconsciously intimidate opponents in athletic contests, especially when the athletes are equal in skill and strength, the researchers suggest.
  In their survey, the anthropologists analyzed the results of four combat sports at the summer games: boxing, tae kwon do, Greco-Roman wrestling and freestyle wrestling.
  In those events, the athletes were randomly assigned red protective gear and other sportwear.
  Athletes wearing red gear won more often in 16 of 21 rounds of competition in all four events.
   _____(48), 19 of 29 classes had more red winners, and only four rounds had more blue winners.
   _____(49).
  The anthropologists made a preliminary analysis of the Euro 2004 international soccer tournament, in which teams wore jerseys of different colors in different matches. They found that five teams scored more goals and won more often when they wore shirts that were predominantly red, as opposed to blue or white jerseys.
  Scientists don't precisely known how wearing red might give athletes an advantage. But the color delivers implicit messages of vigor and danger. When people get angry, their faces turn red. _____(50), so are most Ferraris.
  A Red coloration is associated with aggression in many animals
  B It's also a reason why stop signs are red
  C The effect was the same regardless of weight classes
  D The red effect also might come into play in team sports.
  E But red is not exclusively a male trait
  F Red is more likely male's traits

Avalanche and Its Safety

  An avalanche is a sudden and rapid flow of snow, often mixed with air and water, down a mountainside. Avalanches are __51__ the biggest dangers in the mountains for both life and property.
  All avalanches are caused by an over-burden of material, typically snowpack, that is too massive and unstable for the slope __52__ supports it. Determining the critical load, the amount of over-burden which is __53__ to cause an avalanche, is a complex task __54__ the evaluation of a number of factors.
  Terrain slopes flatter than 25 degrees or steeper than 60 degrees typically have a low __55__ of avalanche. Snow does not __56__ significantly on steep slopes; also, snow does not __57__ easily on fiat slopes. Human-triggered avalanches have the greatest incidence when the snow's angle of rest 1is __58__ 35 and 45 degrees; the critical angle, the angle __59__ which the human incidence of avalanches is greatest, is 38 degrees. The rule of thumb2 is: A slope that is flat   enough to hold snow but steep enough to ski has the potential to generate an avalanche, regardless of the angle. Additionally3, avalanche risk increases with __60__; that is, the more a slope is disturbed by skiers, the more likely it is that an avalanche will occur.
  Due to the complexity of the subject, winter travelling in the backcountry4 is never 100% safe. Good avalanche safety is a continuous __61__, including route selection and examination to the snowpack, weather __62__, and human factors. Several well-known good habits can also __63__ the risk. If local authorities issue avalanche risk reports, they should be considered and all warnings should be paid __64__ to. Never follow in the tracks of others without your own
  evaluations; snow conditions are almost certain to have changed since they were made. Observe the terrain and note obvious avalanche paths where plants are __65__ or damaged. Avoid traveling below others who might trigger an avalanche.
