translation of any text，in any language，at the press of a button.And then there is todays automated translation technology.Services like Google Translate can provide the main idea of a passage of a text.Computers learn to translate by searching for correlations in texts that have been translated by humans.But if youre a newspaper publisher seeking foreign readers or an expert wanting to educate speakers of another language，human translation remains the only option.Martin Benjamin wants to change that.His attempt is called Kamusi and its a multilingual dictionary that contains all the worlds languages.Unlike other online dictionaries, Kamusi is built around concepts as well as words.So the word“spring”， for instance，is linked to several concepts，including the season that comes before summer and a sudden upward or forward motion.This structure could solve one of the biggest challenges for machine translation.Asked to translate “spring in her step” into French，for example，Google chooses printempsthe seasonfor “spring”The inability of computers to deal with homonymswords that are spelled the same but have different meaningsis one reason why machine translations are often so misrepresented.Kamusi avoids this problem by recognizing that “spring” is associated with multiple concepts and prompting the user to say which is relevant.Kamusi has come this far by relying on volunteers and money from the US National Endowment for the Humanities.Benjamin thinks that speakers of minority languages will be motivated to add more terms for free，since they will gain the ability to translate their language into those that are already represented in the dictionary.Benjamin is also trying to get some topdown support：companies that do business in Africa，a continent that is poorly served by existing dictionaries，for instance，might be motivated to pay for large numbers of local words to be added to Kamusi.【解题导语】这是一篇说明文，在评论了普遍使用的电脑翻译的优缺点后，作者介绍了一种新的在线多语言词典：Kamusi。【长难句解读】(1)Benjamin thinks that speakers of minority languages will be motivated to add more terms for free，since they will gain the ability to translate their language into those that are already represented in the dictionary.分析：此句是一个复合句，since引导原因状语从句，主句中的thinks后是that引导的宾语从句，从句中的those后是that引导的定语从句。(2)Benjamin is also trying to get some topdown support：companies that do business in Africa，a continent that is poorly served by existing dictionaries，for instance，might be motivated to pay for large numbers of local words to be added to Kamusi.分析：冒号后的内容是对冒号前内容的进一步解释，冒号后句子的主干是companies might be motivated to.；Africa后的a continent that.是同位语，是对Africa的解释说明；for instance是插入语。1By using automated translation technology，we can_.来源:学#科#网Z#X#X#KAknow the general meaning of a textBread a newspaper published in another languageCeducate speakers of another languageDdistinguish different concepts of a word答案A细节理解题。根据第二段中的“Services like Google Translate can provide the main idea of a passage of a text.”可知，这种自动翻译技术可以让我们知道文章或段落的大意。2Which is the biggest challenge for machine translation according to the passage?ALearners cant learn a language through it.BIt cant offer completely right translation.CIt cant deal with homonyms.DUsers cant search the proper meaning of a word.来源:学&科&网Z&X&X&K答案C细节理解题。由第四段中的“The inability of computers to deal with homonyms”可知，电脑翻译面临的最大挑战之一是无法应对同形异义词。3The advantage of Kamusi is that_.Ait is mainly based on concepts of wordsBit focuses on the origin of wordsCit can recognize the proper meaning of a wordDit has enough words and terms needed答案A细节理解题。根据文章第三段中的“Kamusi is built around concepts as well as words”可知，这种在线词典的特点是它建立在概念的基础上，因此选A。4Which of the following is TRUE according to the passage?AKamusi can translate some of the worlds languages.BThe word “spring”has more than one meaning.CKamusi cant be used by newspaper publishers who seek foreign readers.DIn Africa，there are a variety of languages as well as dictionaries.答案B细节理解题。根据第三段中的”So the wordspring，for instance，is linked to several concepts”可知，spring有好几个意思，故答案为B。根据此段中的“that contains all the worlds languages”可以排除A；通过上文可知，这种在线词典可以解决电脑翻译的缺陷，因此选项C不对；由最后一段中的”a continent that is poorly served by existing dictionaries可知D不对。B体裁：说明文话题：科学发现词数：365难度：建议用时：7分钟Scientists may have discovered the worlds oldest dinosaurnot buried under the earth，but sitting on a shelf.A team led by Sterling Nesbitt found the beasts bones in the Natural History Museum in London.They decided to take a second look at these forgotten fossils，which consist of six vertebrae(椎骨)and an upper arm bone.The scientists studied minerals from the earth where the bones were discovered and compared them with rocks from around the globe.They found that the bones were from the Middle Triassic period,10 million to 15 million years before the oldest known dinosaurs were thought to have existed.The upper arm fossil had traits(特点)seen in dinosaurs and their closest relatives.The shape of the arm bone also matched that of early dinosaurs.Nesbitts team concluded that the specimen was most likely a new species of dinosaur, which they called Nyasasaurus parringtoni.This species was about the size of a large dog.It had a long tail and stood upright on two legs.The newly discovered species proves that the earliest dinosaurs lived in the southern hemisphere.These dinosaurs probably developed alongside several other reptile species before finally taking their place as the dominant life forms on Earth.The fossilized bones were first found near Lake Nyasa in Tanzania by FRex Parrington.Parrington gave the bones to his student Alan Charig.Charig studied the fossils for 40 years.He named the unknown species Nyasasaurus，or “Nyasa lizard”Charig believed the bones were either from the earliest dinosaur or from a very close relative.Others didnt agree with him，so he never published his findings.The fossilized bones were tucked_away in a storeroom at the Natural History Museum，where Nesbitt and his team recently found them.“Whats really neat about this specimen is that it has a lot of history，”Nesbitt said.“Found in the 30s，first described in the 1950s but never published，then its name pops up but is never validated(证实)Now 80 years later，were putting it all together.”Nesbitts team is now planning to do further research on Nyasasaurus parringtonithis time in the field，not in a storeroom!【解题导语】科学家可能已经发现了世界上最古老的恐龙尼亚萨龙，其生存年代比目前已知的最早的恐龙早约一千万至一千五百万年。【长难句解读】They decided to take a second look at these forgotten fossils，which consist of six vertebrae(椎骨)and an upper arm bone.分析：这是一个复合句。which引导了一个非限制性定语从句，修饰前面的these forgotten fossils。译文：他们决定再一次看看这些被遗忘的化石，它们一共包含六块椎骨和一块上臂骨。5What do we know about the species of dinosaur“Nyasasaurus parringtoni”？AIt was as big as a large dog.BIt could stand on two of its legs.CIt lived 10 million to 15 million years ago.DIt had a long neck in its early time.答案A细节理解题。根据第四段第二句“This species was about the size of a large dog.”可知，这个恐龙的大小几乎和一条大狗差不多，因此选A。根据第四段最后一句可知，该恐龙只有两条腿，故B项错误。x k b 1 . c o m6Nesbitt judged the fossils in the museum depending on_.Athe rocks from Lake NyasaBthe minerals in the earthCthe length of the tailDthe weight of the upper arm bone答案B细节理解题。根据第二段第一句“The scientists studied minerals from the earth where the bones were discovered and compared them with rocks from around the globe.”可知，科学家们是利用发现这些恐龙化石的土壤中的矿物质来判断的，故选B。7Why didnt Charig publish his findings?ABecause they werent discovered by himself.BBecause he was afraid of being laughed at.来源:Z#xx#k.Com来源:学。科。网Z。X。X。KCBecause other scientists had different ideas.DBecause his teacher didnt allow him to do it.答案C细节理解题。根据倒数第三段第二句“Others didnt agree with hi
