解析:题干中sold的动作发生在过去,had的动作发生在sold之前,也就是“过去的过去”,故用过去完成时。
【技巧点拨】熟记过去完成时的用法,别无他法。
【典型总结】过去完成时的基本用法归纳过去完成时表示一个动作或状态在过去某一时间或动作之前已经完成或结束,即“过去的过去”;也可以指过去的动作延续到过去的某个时刻。
这里的过去时间可以用某个时间状语表示,也可以通过上下文表示。
1)表示一个动作或状态在过去某一时间或动作之前已经完成或结束,也有可能早已结束或完成。
例如:When he was in Beijing, he visited places where he had played as a child. 他在北京的时候游览了他儿时曾玩过的地方。
2)表示一个过去的动作先于另一过去的动作的用法,这种情况多见于宾语从句。
例如:He remembered that he had left the key at home. 他记得他把钥匙落家了。

并在答题卡上将该选项涂黑.AScientists have claimed a milestone in the drive for new energy—development of the first practical artificial leaf, an advanced solar cell that imitates the process,called photosynthesis(光合作用),that green plants use to make sunlight and water into energy.“A practical artificial leaf has been a dream of scientists for decades,”said Daniel Nocera,who led the research team.“We believe we have made it.The artificial leaf shows particular promise as an inexpensive source of electricity for homes of the poor in developing countries. One can imagine villages in India and Africa soon purchasing an affordable basic power system based on this technology.”The leaf is like the shape of a poker card but thinner.Placed in water in a bright sunlight,it could produce enough electricity to supply a house in a developing country with electricity for a day by splitting water into hydrogen and oxygen, which are stored in a fuel cell to produce electricity.The“artificial leaf”is not a new concept.The first artificial leaf was developed more than a decade ago by John Ttlrner.However, it was impractical for wider use,as it was composed of rare,expensive metals and was highly unstable with a lifespan of barely one day.Nocera’s new leaf overcomes these problems.It is made of inexpensive materials that are widely available,works under simple conditions and is highly stable.Laboratory studies showed that it could operate continuously for at least 45 hours without a drop in activity.The key to this breakthrough is Nocera’s recent discovery of several new powerful,inexpensive catalysts,which are able to accelerate the chemical reaction under simple conditions.Right now, Nocera’s leaf is about 10 times more efficient at carrying out photosynthesis than a natural leaf.Yet he is optimistic that he can boost the efficiency of the device much higher in the future.21.Daniel Nocera describes his artificial leaf as promising in_________________.A.making an artificial plant that can feed itself.B.finding a new kind of catalyst to produce electricity.C.changing the sunlight and water into electricity directlyD.providing electricity for the poor family at a low cost22.According to the passage, catalysts in the artificial leaf________.A.speed up the process of chemical reactionsB.reduce the loss of energy during its operationC.work as a media to store collected energyD.slow down the course of chemical reactions23.The underlined word“it”in the fourth paragraph refers to______.A.photosynthesis B.catalyst used by the solar cellC.Turner’s artificial leaf D.Nocera’s new leaf24.The passage is most probably from_________.A.a science fiction story B.a fairy tale bookC.an advertisement for solar products D.a science news reportBWhen learning a second language,it is important to study the culture of the language you’re learning.Anyone can learn another language’s grammar from a textbook,but what good is this learning if you don’t understand the culture of the person you’re speaking to? Only in learning another language and its culture will you be able to proficiently communicate with a person in that language.There are many ways to enhance your language studies by studying the country’s culture;this can include reading literature,watching movies,or listening to popular music.Many schools in the United States emphasize the importance of culture understanding in language classes.Instead of memorizing only vocabulary words and grammar patterns,classes from elementary schools to universities are teaching literature,pop songs,and films in their classes.From these various mediums students can learn a great deal about the culture of a language they study.These different forms of media can teach various characteristics about the language,culture,and history of a society.Literature can allow you to understand the history and current debates confronting a culture.For example,if you read John Steinbeck’s GraPes of Wrath you can understand the history and problems of ordinary American farmers in the Great Depression.In watching films one can learn about what is popular in a society, and also slang phrases one definitely won’t find in a textbook.In pop songs one can understand what the current craze in a culture is;what kind of music people like to listen to,what that culture finds romantic,and even what the contemporary“cool”viewpoint in that society is.If you truly are interested in learning a language,don’t underestimate the importance of learning about the language’s home culture.Of course one must learn a language’s grammar and vocabulary, but this will only get you so far in actually being able to communicate effectively.So if you are learning a language,take the time to also study the culture.25.The best title for this passage would be________.A.Important Factors in Learning a Second LanguageB.The Importance of Culture in Learning a LanguageC.Effectively Communicating in a Second LanguageD.Why You Should Watch Films and Listen to Music When Learning a Foreign Language26.In the above passage literature is described as an important way to learn _____about a culture.A.history B.political issues C.social issues D.all of the above27.Which of the following opinions was NOT expressed in the passage above?A.Language learning needs to be supplemented by cultural learning.B. Cultural learning can give key insights into a society’s history,language,and current trends.C.A majority of time should be given to cultural learning while learning a second language.D.The key to effective communication is language and cultural proficiency.CAs you grow older, you’ll be faced with some challenging decisions—like should you play soccer or field hockey,or like whether to cut class or try cigarettes.Making decisions on your own is hard enough,but when other people get involved and try to press you one way or another it can be even harder.People who are your age,like your classmates,are called peers.When they try to influence how you act,or get you to do something, it's called peer pressure.It’s something everyone has to deal with—even adults. Let’s talk about how to handle it.Peers can have a positive influence on each other.Maybe another student in your science class taught you an easy way to remember the planets in the solar system.You might admire a friend who is always a good sport and try to be more like him or her.Maybe you got others excited about your new favorite book,and now everyone’s reading it.These are examples of how peers positively influence each other every day.Sometimes peers influence each other in negative ways.For example,a few kids in school might try to get you to cut class with them,your soccer friend might try to convince you to be mean to another player and never pass him the ball,or a kid in the neighborhood might want you to shop lift with him.It is tough to be the only one who says“no”to peer pressure,but you can do it.Paying attention to your own feelings and beliefs about what is fight and wrong can help you know the right thing to do.Inner strength and self-confidence can help you stand firm,walk away, and resist doing something.You’ve probably had a parent or a teacher advising you to“choose your friends wisely”.Peer pressure is a big reason why they say this.If you choose friends who don’t use drugs, cut class,smoke cigarettes,or lie to their parents,then you probably won’t do these things either, even if other kids do.If you continue to face peer pressure and you’re finding it difficult to handle,talk to someone you trust.Don’t feel guilty if you’ve made a mistake or two.Talking to a parent,a teacher,or a school counselor can help you feel much better and prepare you for the next time you face peer pressure.28.For whom is the passage most probably written?A.Students B.Parents C.Teachers D.Counselors29.Both Paragraph 2 and 3 are developed________________.A.by space B.by time C.by stories D.by examples30.In the last three paragraphs,the author mainly____.A.explains why peer pressure is so importantB.gives advice on how to deal with peer pressureC.discusses how peers influence usD.show how to make more good friends31.Which of the following may help handle peer pressure?A.Spending more time with your classmates.B.Taking up more relaxing hobbies.C.Choosing friends with no bad habits.D.Doing what your classmates do.DLook at the keyboard of any standard typewriter or computer.“Q,””W,””E,””R””T”and“Y”are the first six letters.Who decided on this arrangement of the letters? And why?People tried for centuries to invent the typewriter.In 1714 in England,Henry Mill filed a patent for a machine called An Artificial Machine Or Method for the Impressing or Transcribing of Letters,Singly or Progressively one after another, as in Writing,whereby all Writing whatsoever may be Engrossed in Paper or Parchment so Neat and Exact as not to be distinguished from Print.That machine probably didn’t sell because no one could remember its name!The first practical typewriter was patented in the United States in 1868 by Christopher Latham Sholes.His machine was known as the type-writer.It had a movable carriage,a lever for turning paper from line to line,and a keyboard on which the letters were arranged in alphabetical order.But Sholes had a problem.On his first model,his”ABC”key arrangement caused the keys to jam when the typist worked quickly.Sholes didn’t know how to keep the keys from sticking,so his solution was to keep the typist from typing too fast.Sholes asked his brother-in-1aw to rearrange the keyboard so that the commonest letters were not so close together and the type bars would come from opposite directions.Thus they would not clash together and jam the machine.The new arrangement was the QWERTY arrangement typists use today.Of course,Sholes claimed that the new arrangement was scientific and would add speed and efficiency.The only efficiency it added was to slow the typist down,since almost any word in the English language required the typist’s fingers to cover more distance on the keyboard.The advantages of the typewriter outweighed the disadvantages of the keyboard.Typists memorized the crazy letter arrangement,and the typewriter became a huge success.By the time typists had memorized the new arrangement of letters and built their speed,typewriter technology had improved,and the keys didn't stick as badly as they had at first.32.The author thinks the machine invented by Henry Mill could not be sold because__________.A.it was difficult for people to accept new thingsB.there were great disadvantages of the key boardC.the machine could not be distinguished from printD.the name of the machine was too long33.Sholes decided the QWERT arrangement of the keyboard in order to________.A.arrange the letters in alphabetical orderB.cause the keys to jam when the typist worked quicklyC.solve the problem of the keys jammingD.compete with”ABC”key arrangement34.It is infer red that the QWERTV arrangement of the keyboard______.A.is the most scientific arrangement B.adds speed and efficiency of typistsC.keeps the typist from typing too fast D.is easy for typists to memorize35.Which of the following can be the best title of the passage?A.The Arrangement of The Letters on KeyboardB.The Story of Christopher Latham SholesC.How to Invent The TypewriterD.The First Practical Typewriter第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。
