Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 1 to 8.
The world is losing languages at an alarming rate.  Michael Krauss suggested that of the approximately 6,000 human languages alive today, only 350 to 500 are safe from extinction.  Some linguists estimate that a language dies every two weeks or so.  At the current rate, by 2100, about 2,500 native languages could disappear.
Languages become extinct for many reasons.  Through imperialism, colonizers impose their languages on colonies.  Some politicians believe multilingualism will fragment national interests.  Thus they prohibit education in all but the national language.  Another reason for language death is the spread of more powerful languages.  In the world today, several languages, including English, are so dominant in commerce, science, and education, that languages with fewer speakers have trouble competing.
Although in the past, governments have been one of the primary causes of language death, many have now become champions of preserving endangered languages and have had some significant successes.  Two outstanding examples are the revival of Hebrew and Irish.  Hebrew was considered a dead language, like Latin, but is now the national language of Israel.  Irish was not dead, but severely threatened by English when the government of Ireland began its rescue immediately after the establishment of the Irish Free State in 1922.  All students in public schools must now take some classes in Irish and there are Irish programs in major media, such as television and radio. According to the Irish government, approximately 37% of the population of Ireland now speaks Irish.
One of the largest programs to revive languages, Documenting Endangered Languages (DEL), is being conducted by three U.S. government agencies: the National Science Foundation, the National Endowment for the Humanities, and the National Museum of Natural History.  Researchers funded by these agencies are recording interviews with the mostly elderly people who still speak the languages.  Analyses of these interviews will help linguists publish dictionaries and grammars of the languages.  Eventually, linguists hope to establish language-training programs where younger people can learn the languages, carrying them on into the future.
The linguists participating in DEL defend spending millions of dollars to preserve dying languages.  They point out that when a language dies, humanity loses all of the knowledge of the world that that culture held.  Traditional healers in rural areas have given scientists important leads in finding new medicines; aspirin is an example of these.  But one of the most common reasons given by these researchers is that studying languages gives us insight into the radically different way humans organize their world.  David Lightfoot, an official at the National Science foundation, gives the example of Guguyimadjir, and Australian aboriginal language, in which there are no words for “right” or left,” only for “north,” “south,” “east,” and “west.”
Many researchers are optimistic that the efforts to save dying languages will succeed, at least in part.  Bruce L. Cole, Chairman of the National Endowment for the Humanities, said, “Not only is this a time of great potential loss, it is also a moment for enormous potential gain.  In this modern age of computers and our growing technological capabilities, we can preserve, assemble, analyze, and understand unprecedented riches of linguistic and cultural information.”
According to the passage, what would linguists in the DEL project like to do someday?
A.Record interviews with elderly people
B.Get funding from the government
C.Teach endangered languages to young people
D.Write a dictionary and grammar for Irish

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions from 36 to 42.
Although speech is the most advanced form of communication, there are many ways of communicating without using speech. Signals, signs, symbols and gestures may be found in every known culture. The basic function of a signal is to impinge upon the environment in such a way that it attracts attention, as, for example, the dots and dashes of telegraph circuit. Coded to refer to speech, the potential for communication is very great. Less adaptable to the codification of words, signs also contain meaning in and of themselves. A stop sign or a barber pole conveys meaning quickly and conveniently.
Symbols are more difficult to describe than either signals or signs because of their intricate relationship with the receiver's cultural perceptions. In some cultures, applauding in a theater provides performers with an auditory symbol of approval. Gestures such as waving and handshaking also communicate certain cultural messages.
Although signals, signs, symbols and gestures are very useful, they do have a major disadvantage. They usually do not allow ideas to be shared without the sender being directly adjacent to the receiver. Without an exchange of ideas, interaction come to a halt. As a result, means of communication intended to be used for long distances and extended periods must be based upon speech. To radio, television and the telephone, one must add fax, paging systems, electronic mail, and the Internet, and no doubts but that there are more means of communication on the horizon.
Applauding was cited as an example of ________.           
A.a sign
B.a gesture
C.a signal   
D. a symbol

Your teacher gives you the following brochure about crime. Read the information and answer the questions.
How to Avoid Being Mugged
          A surprisingly large number of people have had first-band experience of some sort of crime in the streets, the most common of which is mugging. In the city of Chicago alone, there are about 6,000 muggings every year. Here are some tips in order to avoid joining the growing list of people who have been mugged.
          How can a mugger be spotted?
          Be wary of loiterers who seem to be window shopping or who aren’t really doing anything. Muggers need time to find the right victim, so they neither hide nor walk very quickly. They often ask for spare change or what the time is. These are tricks to distract their victims, and also to figure out if you have any expensive jewellery or items worth stealing. Finally, be suspicious of anyone who is wearing clothing which hides their identity, such as a hooded jacket.
          What kind of victims do muggers search for?
          Muggers love solitary individuals, so be sure to stay where the people are. Avoid empty streets and alleyways, and whenever possible, try to walk with a friend. Walk confidently and take long steps. Muggers do not like people who are relaxed and seem sure of themselves. It is also a good idea to look a potential mugger in the eye, for the same reason. However, if the mugger is an aggressive type, establishing eye contact may backfire, as he/she might see it as a challenge. So if your confident look is met with an angry stare, be the first to look away. Lastly, do not dress in a way that makes you stand out. If you are a tourist, try to dress like a local.
          What can you do if you realize you are a target?
          It is sometimes a good idea to act unpredictably, perhaps by acting crazy or shouting. If there are people around, shouting “Fire!” is more effective than “Help!”. However, in the majority of cases muggers carry dangerous weapons, so it’s probably safer to go along with their demands. If a mugger forces you into your car, you will probably be told to drive to an ATM and withdraw cash. Don’t worry, though, because most banks will refund any money withdrawn while being robbed if you report the incident to the police.
What is the best thing to do when you are mugged?
A.shout “help” loudly     
B.obey the mugger
C.call the police  
D.use a dangerous weapon
