12.The time may soon come when we say goodbye to most of the world's languages.Today humans express themselves in over 6,000different languages.But that is quickly changing.Many scientists say that over half of these languages will disappear within the next 50years.After 100years,the languages used in the world will not be more than 20.
Why?It is because people from different cultures live and work together much more often than before.This brings changes.The languages of the world's main culture are replacing the languages of the smaller cultures.Most international trade takes place in world languages such as English.People respect their own cultures and traditions,but when it comes to getting a job,knowing a world language is often necessary.It may mean the difference between success and failure.
Technology works on the change of languages in an even more amazing way.Modern media such as radio and television give young people in developing countries much knowledge about the world.But this knowledge doesn't come in words from the mouths of their parents or the elders in their neighborhood.It usually comes in the language of a different culture.
People in different cultures think it good for them to share a popular language.They can quickly share ideas and work together.Knowing the same language means easier communication and is a basis for trust.
Is the death of a small local language such a terrible thing?The answer is maybe.Many cultures may have words for many useful things we know nothing about.If their languages die,their valuable wisdom may be lost forever.The future of the world's language depends on our actions now.Will we protect endangered languages or allow them to quietly disappear?
Time will have the last word.
21.Scientists say that within 50years,perhaps,there will be onlyAlanguages in the world.
A.a(chǎn)round 3,000          B.over 3,000         C.6,000          D.less than 20
22.In"the languages of the world's main cultures are replacing the languages of the smaller cultures."the underlined word"replace"means"C".
A.to put something back into a correct place       
B.to find good place for something
C.to take the place of something.
D.to decide how important something is
23.The passage says that if all the people in the world knew a popular world language,A.
A.it would be easier for them to share their ideas
B.people would have no trouble in learning language
C.lessons at schools would be taught in the language
D.people would respect their own culture more
24.According to the passage,if nobody spoke the languages of smaller cultures,A.
A.many of the words for things we do not know would be lost
B.knowledge would come from the mouths of the elders
C.people would have difficulty in working together
D.there would be no smaller cultures.

分析 隨著國(guó)際貿(mào)易和網(wǎng)絡(luò)交往,世界的語(yǔ)言越來越趨于縮小化,一些小的語(yǔ)種逐漸在交流中喪失,但在這些小語(yǔ)種中包含著我們極少了解的一些知識(shí),我們要從現(xiàn)在開始,改變這種現(xiàn)狀.

解答 21-24  ACAA
21.A 考查推理判斷題.根據(jù)第一段提到But that is quickly changing.Many scientists say that over half of these languages will disappear within the next 50 years.在未來的五十里6000種語(yǔ)言將會(huì)減少一半,故選A項(xiàng).
22.C 考查細(xì)節(jié)理解題.根據(jù)第二段提到The languages of the world's main culture are replacing the languages of the smaller cultures世界主要的文化將要取代小的文化,故選C項(xiàng).
23.A 考查推理判斷題.根據(jù)第四段提到Knowing the same language means easier communication and is a basis for trust共同的語(yǔ)言是交流的基礎(chǔ),故選A項(xiàng).
24.A 考查推理判斷題.根據(jù)第五段提到Many cultures may have words for many useful things we know nothing about.許多語(yǔ)言包含我們所不了解的內(nèi)容,故選A項(xiàng).

點(diǎn)評(píng) 做閱讀時(shí)經(jīng)常犯錯(cuò)的主要原因是,僅憑讀過文章后殘留在腦海中的一絲印象來勾選答案,這樣便很容易掉入出題人故意設(shè)布下的題目陷阱.所謂閱讀理解,對(duì)于題目的理解一定要忠實(shí)于原文,因此,每一道題都應(yīng)該與原文作全面的對(duì)比與核查,再得出答案.也就是說,閱讀理解的每一道題目,在原文都應(yīng)該有明確的出處,我們把這一出處叫做原文相關(guān)句,(1)排除與原文相關(guān)句主題不一致的選項(xiàng)(2)排除與原文相關(guān)句態(tài)度相反的選項(xiàng)  (3)排除用于過于極端或負(fù)面的選項(xiàng)(4)注意結(jié)合文章主旨和主題去排除.

3.More than 200scientists have completed a two-year study to identify the most natural and undeveloped areas on Earth.Their findings are reported in a new book called Wilderness:Earth's Last Wild Places.The book describes 37wilderness areas around the world.Each has an area greater than 10,000square kilometers.The study considered only areas where at least 70% of all plants are native.
North and South America are home to the largest number of wilderness areas.There are 16such areas,from southern Argentina to Alaska and northern Canada.Africa has 8wilderness areas,including the thick forests and the grasslands.Australia and New Guinea (幾內(nèi)亞) share 6areas.Europe has 3areas and Asia has 2.The Arabian Desert and Antarctica also are considered wilderness areas.
The largest wilderness area is the Boreal Forest (北方森林).It extends for 16-million square kilometers south of the Arctic Circle.The Boreal Forest extends across Alaska,Canada,northern Europe and Russia.The smallest of the 37wilderness areas is the Sundarbans.It is the world's largest tidal mangrove forest (紅樹林).It covers 10,000square kilometers of land at the mouth of the Ganges River in India and Bangladesh (孟加拉國(guó)).
The study found that wilderness areas cover about 46% of the Earth's land surface.However,they are home to less than 2.5% of the world's population.Nineteen of the wilderness areas have only about one person for each square kilometer.Native people usually live in these areas.
Wilderness areas help to influence the world's weather systems and rainfall.They are also home to many plants and animals.Population growth and the spread of agriculture and mining operations threaten wilderness areas.But just 7% of all such areas have some form of official protection.

66.What does the author think of the wilderness areas around the world in the book?C
A.Primitive    B.Permanent    C.Precious    D.Perfect
67.The writer describes the wilderness areas to show that theyC.
A.a(chǎn)re worth the public support
B.can attract readers'attention
C.need to be stressed as resources
D.a(chǎn)re seen on every continent
68.According to the 4th paragraph,we can draw a conclusion that the 37wilderness areas areD.
A.deserted    B.crowded   C.uncontrolled   D.undeveloped

20.A.The power and habit of thinking 
B.The value of previous education
C.The correctness in using mother tongue 
D.The development of an educated man 
E.The possession of gratitude 
F.Refined and natural manners  
 
76.C
   The first characteristic of an educated man is the precision of the use of the native language.When one hears English well spoken,with pure diction,correct pronunciation,and an almost unconscious choice of the right word,he recognizes it at once.How much easier he finds it to imitate English of the other sort.
77.F
    When manners are artificial and forced,no matter what their form,they are bad manners.When,however,they are the natural expression of fixed habits of thought and action,and when they reveal a refined and cultivated nature,they are good manners.There are certain things that gentlemen do not do,and they do not do them simply because they are bad manners.
78.A
   Human beings for the most part live wholly on the surface or far beyond the present moment and that part of the future that is quickly to follow it.They do not read those works of prose and poetry which have become classic because they reveal power and habit of reflection and induce that power and habit in others.When one reflects long enough to ask the question how?He is on the way to knowing something about science.
79.D
    An educated man continues to grow and develop from birth to his dying day.His interests expand,his contacts multiply,his knowledge increases,and his reflection becomes deeper and wider.It would appear to be true that not many human beings,even those who have had a school and college education,continue to grow after they are twenty-four or twenty-five years of age.By that time it is usual to settle down to life on a level of more or less contented intellectual interest and activity.The whole present-day movement for adult education is a systematic and definite attempt to keep human beings growing long after they have left school and college,and therefore,to help educate them.
80.B
    The more visionary dreamer,however charming or however wise,lacks something that an education requires.The power to do may be exercised in any one of a thousand ways,but when it clearly shows itself,that is evidence that the period of discipline of study and of companionship with parents and teachers has not been in vain.

7.For several years,Americans have enjoyed teleshopping-watching TV and buying things by phone.(71)AIn a number of European countries,people can turn on their TVs and shop for clothes,jewelry,food,toys,and many other things.

(75)EThey will have to be more careful about the quality of the things they sell.They will also have to work harder to sell things that the buyers cannot touch or see in person.

A.Now teleshopping is starting in European
B.They call teleshopping"Junk on the air"
C.Teleshopping is becoming popular in Sweden.
D.German businesses are hoping this new teleshopping will help them sell more things
E.The need for high quality means that European teleshopping companies will have to be different from the American companies.
F.Teleshopping is popular among people
G.German teleshopping business is controlled by American.
