surprised, i read diary after diary, each expressing a _9_ theme.“didnt i teach them anything? i described the entire philosophical framework of western thought and laid the historical _10_ for all

uss carnegie mellon university (cmu) and germanys university of karlsruhe, announced last week that it may soon be reality. he and his team have invented software and hardware that could make it far easier for people who speak different languages to understand each other.one application, called lecture translation, can easily translate a speech from one language into another. current translation technologies typically limit speakers to certain topics or a limited vocabulary. users also have to be trained how to use the program.another prototype (雏形机) can send translations of a speech to different listeners depending on what language they speak. “it is like having a simultaneous translator right next to you but without disturbing the person next to you，” waibel said.prefer to read? socalled translation glasses transcribe (转录) the translations on a tiny liquidcrystal (液晶) display (lcd) screen.then theres the muscle translator. electrodes capture the electrical signals from facial muscle movements made naturally when a person is mouthing words. the signals are then translated into speech. the electrodes could be replaced with wireless chips implanted in a persons face, according to researchers.during a demonstration held last thursday in cmus pittsburgh campus, a chinese student named stan jou had 11 tiny electrodes attached to the muscles of his cheeks, neck and throat. then he mouthed without speaking aloud a few words in mandarin (普通话) to the audience. a few seconds later, the phrase was displayed on a computer screen and spoken out by the computer in english and spanish: “let me introduce our new prototype.”this particular gadget(器具)，when fully developed, might allow anyone to speak in any number of languages or, as waibel put it, “to switch your mouth to a foreign language”. “the idea behind the universitys prototypes is to create good enough bridges for crosscultural exchanges that are becoming more common in the world，” waibel said.with spontaneous (自发的) translators, foreign drivers in germany could listen to traffic warnings on the radio, tourists in china could read all the signs and talk with local people, and leaders of different countries could have secret talks without any interpreters there.16which of the following statements is not true?aa lecture translation can translate what you said into other languages easily.bthere is no muscle translator in the world now.cmuscle translators can translate what you think into speech if you just move your mouth.dthe spontaneous translators will help us a lot.17what kind of equipment is not mentioned in this passage?alecture translation. bmuscle translator.cmultiple translator. dtranslation prototype.18whats the final destination of inventing the language translators?ato make cultural exchanges between different countries easier.bto help students learn foreign languages more easily.cto make people live in foreign countries more comfortably.dto help people learn more foreign languages in the future.19what can be inferred from the seventh paragraph?athe translator is so good that it can translate any language into the very language you need.bthe translator is becoming more and more common in the world as a bridge.cwith the help of the translator, you only need to open your mouth when you want to say something without saying the exact words at all.dthe translator needs to be improved before being put into market.20where can this passage probably be from?aa newspaper. ba magazine on science.ca fairy tale. da scientific fantasy book.bthe two thingssnow and mountainswhich are needed for a ski area are the two things that cause avalanches(雪崩), large mass of snow and ice crushing down the side of a mountainoften called “white death”it was the threat of the avalanche and its record as a killer of man in the western mountains that created the snow ranger. he first started on avalanche control work in the winter of 193738 at alta, utah, in wasatch national forest.this mountain valley was becoming well known to skiers. it was dangerous. in fact, more than 120 persons had lost their lives in 1936 and another 200 died in 1937 as a result of avalanches before it became a major ski area. thus, development of alta and other major ski resorts in the west was dependent upon controlling the avalanche. the forest service set out to do it, and did, with its corps(团队)of snow rangers.it takes many things to make a snow ranger. the snow ranger must be in excellent physical condition. he must be a good skier and a skilled mountain climber. he should have at least a high school education, and the more college courses in geology, physics, and related fields he has, the better.he studies snow, terrain, wind, and weather. he learns the conditions that produce avalanches. he learns to forecast avalanches and to bring them roaring on down the mountainsides to reduce their killing strength. the snow ranger learns to do this by using artillery(炮), by blasting with tnt, and by the difficult and skillful art of skiing avalanches down.the snow ranger, dressed in a green parka which has a bright yellow shoulder patch, means safety for people on ski slopes. he pulls the trigger(扳机) on a 75 mm recoilless rifle(无后座力步枪), skis waist deep in powder testing snow stability, or talks with the ski areas operator as he goes about his work to protect the public from the hazards(危险)of deep snow on steep mountain slopes.21. the snow rangers are employees of _.athe forest service bthe resource bureaucthe tourist board dthe sports

glow般的自豪感被后面阅读学生的日记时的悲伤所替代了。8b学生对老师的第一节课不感兴趣，所以猜测可能下一节会好些。9c通过上下文得知，学生的日记里面记载的是相似的主题，即对老师的教学不满意。10d从前文中的entire philosophical framework可知此处的background“背景”是最佳答案。12空后的enough background也有提示。11d“我”是通过读学生的日记渐渐明白过来的。12b老师是提出“有趣”的问题而不是不寻常的问题，要符合全文的逻辑。13adraw ones conclusion 是固定搭配，意为“得出结论”。14c这些学生喜欢as directly and clearly as possible的精准的信息，容易误选standard“标准信息”。15d从后文中的“我”知道如何教中国学生了，说明跟以前比较“我”已经是个更好的老师了。.a本文是一篇说明文，内容是有关翻译机器发明成果的阐述。16b细节理解题。根据文章第五、六段可推出b项是错误的。17c推理判断题。在短文第二段中提到了lecture translation，在第三段中提到了prot
