17、ds regularly 20 After so many years of studying English, you may still get confused like you first come here just because of the slang the students use! Now let us see how “street talk“ and “regional talk“ are. Street talk is a way to categorize many “hip“ words used on the street. There is a playfu

18、lness about street talk. What about the word “hip? “ You might have thought that this was derived from “hippie“ -a follower of social fashion in the 1960s and 70s. But no, it comes from a much older usage, the word “hep“. The word “hip“ is marked as “out-of-date slang“. But it seems to have come bac

19、k into fashion. Other bits of old-fashioned slang are also popular here, such as “cool“. The expression “thats cool“ is often used to agree to a suggestion. The problem with slang and trendy expressions in general is that they change fast, so that only those who are using them all the time can keep

20、up. A great deal of slang used by students comes from television and films, especially from “catch phrases“ that are used by characters in TV programmes or films. A “catchphrase“ is a phrase that a particular character repeats. If you live here among students, go out to the cinema, watch similar pro

21、grames and listen to popular music, you might find yourself using slang without even thinking. If you meet students from outside London and the south-east, you may notice that local people sometimes dont use textbook English. Traditional dialects are dying out here. But there are still many regional

22、 variations in the way English is used. One example is the way people address each other. If you are in Newcastle, you might hear people ( particularly women) refer to each other as “hinny“-a common term of endearment. “Hinny“ refers to the “sterile hybrid offspring of a male horse and female donkey

23、,“ but that is not what they mean when they call you “hinny“ in Newcastle! Probably, the word theyre using is the local form of “honey“. Other parts have their own endearments. If someone in Glasgow calls you“ hen“ or someone in Nottingham adds “duck“ to the end of what they say, they re being frien

24、dly, not rude. Younger people tend to use these terms less. And these phrases are only the tip of the iceberg when it comes to the rich regional variations found in informal speech here today. So after you think you ve got the hang of slang, do you dare use it yourself? Take care ! Most informal and

25、 colloquial usage marks you as coming from a particular social background-to a native speaking thing. Since English is not your first language, people may find it odd if you use slang. But you should spare time for chatting with, and learning from native - speakers and try to understand different us

26、ages. As you gain experience, you 11 learn which phrases are safe to use. But make sure you don t use them in the wrong place. Stick with official English whenever in doubt! 21 The author is a _. （ A） travel guide （ B） language professor （ C） school supervisor （ D） talkshow host 22 What does the wor

27、d “hip“ mean in this passage? （ A） It is derived from “hippie“. （ B） It means following the social fashion in the 1960s and 1970s. （ C） It comes from a more recent useage. （ D） It means“ out - of - date slang“. 23 The problem with slang and trendy expressions is _. （ A） that they are out - of - date

28、 （ B） that they are difficult （ C） that they change fast （ D） that they mean nonsense 24 What does“ hinny“ mean in Newcastle? （ A） The sterile hybrid of a horse and a donkey. （ B） A common term of cursing. （ C） The local form of “hello“. （ D） A usual way of affection. 25 The author asks learners _.

29、（ A） to never use slang （ B） to understand what these slang words mean （ C） to take time to use slang often （ D） to stick with official English 25 A team of international researchers has found new evidence that an endangered subspecies of chimpanzee is the source of the virus that causes acquired im

30、mune deficiency syndrome (AIDS) in humans. Experts said the finding could lead to new treatments for AIDS and contribute to the development of a vaccine against the disease. The research team said the chimp - a subspecies known as Pan troglodytes troglodytes native to west central Africa - carries a

31、 simian immunodeficiency virus (SIV) that is closely related to three strains of human immunodeficiency virus ( HIV), the virus that causes AIDS. One of these strains, HIV - 1, has caused the vast majority of the estimated 30 million HIV infections around the world. The researchers are uncertain whe

32、n the chimp virus, called SIVcpz (for simian immunodeficiency virus chimpanzee), first infected humans, although the oldest documented case of HIV has been linked to a Bantu man who died in Central Africa in 1959. But they said the virus, which does not appear to harm the chimps, was most likely tra

33、nsmitted to humans when hunters were exposed to chimp blood while killing and butchering the animals for food. Once transmitted to humans, the researchers believe the virus mutated into HIV -1. Team leader Beatrice Hahn, an AIDS researcher at the University of Alabama in Birmingham, said the chimps

34、have probably carried the virus for hundreds of thousands of years. Since humans have likely hunted the animals since prehistoric times, Hahn said the virus may have jumped to humans on many occasions, but was not trans, nined widely among humans until the 20th century Increased hunting of the chimp

35、anzees, along with human migration to African cities and changing sexual mores, could help explain the recent epidemixc, Hahn said. Scientists had long suspected that a nonhuman primate was the source of HIV - 1. Earlier studies suggested that the sooty mangabey monkey, a native of West Africa, was

36、the likely source of HIV - 2 - a rarer torm of the AIDS virus that is transmitted less easily than HIV - 1. However, only a few samples of SIV strains exist, making it difficult for researehers to confidently connect the strains to HIV - 1. As part of their effort to discover the source of HIV - 1,

37、the research team studied the four known samples of SIVcpz. They learned that three of the four samples came from chimps belonging to the subspecies P.t. troglodytes. The remaining sample came from another subspecies, Pan troglodytes schweinfurthii, which inhabits East Africa. The team then compared

38、 the SIVcpz strains to each other and found that all three of the viruses from P. t. troglodytes were closely related, while the virus from P.t. schweinfurthii was genetically different. Next they compared the SIVepz strains to the main subgroups of HIV - 1, known as M, N, and O. Their comparisons s

39、howed that the P.t. troglodytes viruses strongly resembled “all three HIV -1 subgroups. Additional evidence that HIV - 1 could be linked to P. t. troglodytes came when the researchers examined the chimps natural habitat. The researchers quickly discovered that the chimps live primarily in the West A

40、frican nations of Cameroon, Central African Republic, Gabon, Equatorial Guinea, and Republic of the Congo the geographic region where HIV - 1 was first identified. Upon closer study, the researchers learned that the chimps were being killed in growing numbers for the so - called bush meat trade, a t

41、rend assisted by the construction of new logging roads in once remote forests. The researchers said that continued hunting of the animals meant that many people are still likely to be exposed to SIVepz, increasing the risk of additional cross - species transmissions. Many AIDS researchers welcomed t

42、he teams finding, but said the new work had not proved the connection definitively. Most of the doubts centered on the difficulty of drawing conclusions from such a small number of SIVepz samples. Because so few samples exist - all drawn from chimps in captivity - researchers do not know how prevale

43、nt the virus is among wild chimps, or how the virus is transmitted. Doubts are likely to persist until the course of the virus is studied in chimps in the wild. Some health experts said the finding could have far- reaching implications for combating AIDS. Because SIVepz does not cause the chimps to

44、become ill, researchers believe that the animals disease - fighting immune systems may have developed a defense against the virus. Since chimps are 98 percent genetically similar to humans, learning more about the chimps immune systems could shed light on new ways to prevent and treat AIDS in humans

45、. Discovering how the chimps immune system controls the virus, for example, could help researchers develop a vaccine that generates a similar immune -system response in humans. Other experts noted that even if the finding does not help in the fight against AIDS, it provides strong evidence that dang

46、erous viruses can be transmitted to humans from wild animals, in some cases, the viruses may be harmless to the host animals, but cause sickness and death when transmitted to humans. As people increasingly venture into remote animal habitats, some scientists believe there is a growing risk of new hu

47、man exposures to previously unknown disease- causing microbes. In the meantime, widespread slaughter of the chimps could make further study of P. t. troglodytes difficult. The wild chimp population, which exceeded 1 million animals in the early 20th century, is now believed to number fewer than 100,

48、000. “We cannot afford to lose these animals, either from the animals conservation point of view or a medical investigation standpoint,“ said Hahn. “It is quite possible that the chimpanzee, which has served as the source of HIV - 1, also holds the clues to its successful control. “ 26 The significa

49、nce of the finding is that _. （ A） people now know the number of chimpanzees is much smaller than expected （ B） it may make it possible for scientists to discover new ways of treating AIDS （ C） it proves some deadly human diseases can also be transmitted to wild animals （ D） it Will soon help the scientists develop a vaccine that prevents the AIDS virus 27 According to Hahn, all the following increase the transmission of AIDS virus EXCEPT _. （ A） hu
