8．One in ten teens says they use"study drugs"to improve their performance in school．So-called"study-drugs"refer to prescription medicines（處方藥） used to treat ADHD（注意力缺乏癥）．But most of parents have no understanding of the problem，a new study finds．
In January，2013，researchers from the University of Michigan Mott Children's Hospital did a national survey of more than seven hundred families with teens．They found that only one percent of parents believe their child has taken a study drug．
Yet in a 2012 University of Michigan study，ten percent of second-year high school students and twelve percent of third-year students say they use a study drug．
The misuse of stuffy drugs didn't come to the attention of almost all parents．"What we found in this survey is a clear mismatch（不相符），"said Dr．Matthew Davis，one of the researchers．"It is a mismatch between what parents believe and what their children were reporting．"
"We know teens believe that these drugs can improve their grade，"Davis said．"But these prescription medicines are drugs．And teens who use them without a prescription are taking a serious risk．"
The new survey showed that fifty-four percent of white parents were"very concerned"about their child taking study drugs，compared with thirty-eight percent of the Hispanic （拉美的） parents and thirty-seven percent of black parents．
However，just twenty-seven percent of parents surveyed talked to their teens about using study drugs．Of these parents，forty-one percent were black，twenty-seven percent were white and seventeen percent were Hispanic．
Students with a prescription for an ADHD drug should be required to keep their medicines in a safe place．Seventy-nine percent of parents think so，the survey shows．This may help preventitfrom being shared or used by other students．
32．According to paragraph 4，Dr．Davis thinks．D
A．the 2012 University of Michigan st udy is untrue
B．it is a good way to take study drugs to treat ADHD
C．it is necessary to do another new survey about study drugs
D．some parents still don't realize the study drug problem
33．Dr．Davis believed using study drugs to improve grades．A
A．is bad for health    B．is worth a try   C．sometimes works   D．causes little harm
34．What does the underlined word"it"in the last paragraph refer to？A
A．The study drug     B．ADHD．C．The survey．D．A safe place．．
35．What is the purpose of this text？C
A．To give useful advice．
B．To introduce a new drug．
C．To report a research result．
D．To explain what ADHD is．

分析 每十個青少年中就有一個說他們使用"學(xué)習(xí)藥物"來提高他們在學(xué)校的表現(xiàn)．但是父母們不能意識到使用這種藥物的危害性．本文是對于這種現(xiàn)象的調(diào)查結(jié)果的介紹．

解答 32．D 細(xì)節(jié)理解題．第四段的提出的問題是The misuse of stuffy drugs didn't come to the attention of almost all parents幾乎所有家長都不注意使用不衛(wèi)生的藥物．然后引用的DrDavis 一個研究人員的話來說明這個觀點，所以他的話是為了說明這個父母們?nèi)匀徊荒芤庾R到用藥問題，所以答案選D．
33．A．推理判斷題．根據(jù)教授的話"But these prescription medicines are drugs．And teens who use them without a prescription are taking a serious risk．但是這些處方藥是藥物，而那些沒有處方的青少年服用的藥物則是一個嚴(yán)重的風(fēng)險．可以推斷出他認(rèn)為這種藥對于健康是有危害的，所以答案選A．
34．A 猜測詞義題．根據(jù)最后一段的內(nèi)容，這項研究表明，這可能有助于防止它被其他學(xué)生共享或使用．本文主要就是介紹study drug的調(diào)查情況，本句中的it指的就是本文中的study drug，
35．C 寫作意圖題．根據(jù)第一段最后一句But most of parents have no understanding of the problem，a new study finds．但一項新的研究發(fā)現(xiàn)，大多數(shù)父母對這一問題并不了解．下文作者就本次調(diào)查情況及其結(jié)果進行了介紹，所以答案選C．

點評 閱讀理解題測試考生在閱讀基礎(chǔ)上的邏輯推理能力，要求考生根據(jù)文章所述事件的邏輯關(guān)系，對未說明的趨勢或結(jié)局作出合理的推斷；或根據(jù)作者所闡述的觀點理論，對文章未涉及的現(xiàn)象、事例給以解釋．考生首先要仔細(xì)閱讀短文，完整了解信息，準(zhǔn)確把握作者觀點．

7．The famous director of a big and expensive movie planned to film a beautiful sunset over the ocean，so that the audiences could see his hero and heroine in front of it at the end of the film as they said goodbye to each other forever．He sent his camera crew out one evening to film the sunset for him．
The next morning he said to the men，"Have you provided me with that sunset？"
"No，sir，"the men answered．
The director was angry．"Why not？"he asked．
"Well，sir，"one of the men answered，"we're on the east coast here，and the sun sets in the west．We can get you a sunrise over the sea，if necessary，but not a sunset．"
"But I want a sunset!"the director shouted．"Go to the airport，take the next flight to the west coast，and get one．"
But then a young secretary had an idea．"Why don't you photograph a sunrise，"she suggested，"and then play it backwards？Then it'll look like a sunset．"
"That's a very good idea!"the director said．Then he turned to the camera crew and said，"Tomorrow morning I want you to get me a beautiful sunrise over the sea．"
The camera crew went out early the next morning and filmed a bright sunrise over the beach in the middle of a beautiful bay．Then at nine o'clock they took it to the director．"Here it is，sir，"they said，and gave it to him．He was very pleased．
They all went into the studio．"All right，"the director explained，"now our hero and heroine are going to say goodbye．Run the film backwards so that we can see the‘sunset'behind them．"
The"sunset"began，but after a quarter of a minute，the director suddenly put his face in his hands and shouted to the camera crew to stop．
The birds in the film were flying backwards，and the waves on the sea were going away from the beach．
24．Why did the director want to send his crew to the west coast？C
A．Because he changed his mind about getting a sunset．
B．Because he was angry with his crew．
C．Because he wanted to get a scene of sunset．
D．Because it was his secretary's suggestion．

A．because he was moved to tears
B．a(chǎn)s he saw everything in the film moving backwards
C．a(chǎn)s the sunrise did not look as beautiful as he had imagined

3．A new study，conducted by British company Mindlab International，has found that listening to music at work increases accuracy and speed，The Telegraph reported．Perhaps，some parents disagree with this idea，saying，"Switch off the music and Concentrate!"Well，if that's the case with your parents，you might now be able to convince them that you have science on your side．
The company gave 26 participants a series of different tasks for five days in a row，including spell checking，mathematical word problems，data entry，and abstract reasoning．The participants completed these tasks while listening to music or no music at all．
The results showed that while music was playing，88% of participants produced their most accurate test results and 81% completed their fastest work．David Lewis，chairman of Mindlab International，told The Telegraph，"Music is a very powerful management tool if you want to increase not only the efficiency of your workforce but also their emotional state…they are going to become more positive about the work．"
However，you may have a list of your favorite songs，but not all kinds of music match all homework．For maths or other subjects involving numbers or attention to detail，you should listen to classical music，the study found．In the study，pop music enabled participants to complete their tasks 58% faster than when listening to no music at all．If you are reviewing your English writing，pop music is the best choice，as it is the best kind for spell checking．It cut mistakes by 14%，compared to listening to no music．After finishing your homework，do you often take time to check your answers？Maybe，some dance music is suitable for you．

28．Which of the following can be the best title for the passage？B
A．We cannot live without music            B．Music helps us to learn
C．Different music，different lives         D．Music in the classroom．
29．What did the participants have to do in the study？C
A．Persuade their parents to listen to music．
B．Listen to the same music together．
C．Finish tasks with music or without music at all．
D．Try their best to choose the most suitable music．
30．What does the underlined word"they"refer to in Para 3？A
A．participants                             B．results
C．tests                                        D．tools
31．When you review your English writing，what kind of music is the best choice？B
A．Classical music                            B．Pop music
C．Dance music                                D．Rock music．

20．Besides entertainment and beautiful lanterns，another important part of the Lantern Festival，or Yuanxiao Festival is eating small dumpling balls made of glutinous rice flour．We call these balls Yuanxiao or Tangyuan．Obviously，they get the name from the festival itself．It is said that the custom of eating Yuanxiao originated during the Eastern Jin Dynasty in the fourth century，then became popular during the Tang and Song periods．The fillings inside the dumplings or Yuanxiao are either sweet or salty．Sweet fillings are made of sugar，walnuts，sesame（芝麻），osmanthus flowers（桂花），rose petals，sweetened tangerine（橘子） peel，bean paste，or jujube paste（棗泥）．A single ingredient or any combination can be used as the filling．The salty is filled with minced meat（肉末兒），vegetables or a mixture．
The way to make Yuanxiao also varies between northern and southern China．The usual method followed in southern provinces is to shape the dough of rice flour into balls，make a hole，insert the filling，then close the hole and smooth out the dumpling by rolling it between your hands．In North China，sweet or nutmeat stuffing is the usual ingredient．The fillings are pressed into hardened cores，dipped lightly in water and rolled in a flat basket containing dry glutinous rice flour．A layer of the flour sticks to the filling，which is then again dipped in water and rolled a second time in the rice flour．And so it goes，like rolling a snowball，until the dumpling is the desired size．The custom of eating Yuanxiao dumplings remains．This tradition encourages both old and new stores to promote their Yuanxiao products．They all try their best to improve the taste and quality of the dumplings to attract more customers．
33．Which of the following is NOT true？B
A．The custom of eating Yuanxiao dates back to the fourth century．
B．Sweet Yuanxiao are usually made in southern China．
C．Sugar，rose petals and minced meat are all fillings of Yuanxiao．
D．People in northern China usually make Yuanxiao by rolling like a snowball．

A．Jin Dynasty           B．South Korea      C．China        D．Tang and Song period
35．Choose the right order of making Tanguan in southern provinces．A
（1）make a hole and insert the filling          
（2）roll the dough between your hands
（3）shape the dough of rice flour into balls     
（4）close the hole
（5）prepare some rice flour
A．（5）（3）（1）（4）（2）

18．A professional skateboarder is probably facing jail time after uploading a video that shows he was skating at a shocking 68mph through the middle of traffic．
South African skater Decio Lourenco faces the charges after Cape Town city officials say his high-speed sating actually attracted a speed camera．The speed limit for skating in the town of Lourenco is 37mph．"The boy's behavior was very dangerous．He might cause one of the motorists to panic and crash into other vehicles，which can lead to a large number of deaths．We have already had such cases on that road before，"safety spokesman Jean-Pierre Smith，told the New York Daily News．"If we don't take action against him，every other skateboarder will stry it and one of them will come to a sticky end．"
It's hard to deny that what the boy did was dangerous，particularly with oncoming traffic in the opposite lane．But Lourenco is a professional and Kloof Nek，the road he speeds down，has been used for professional skateboarding events in the past．Besides，at the end of his YouTube video of the dangerous behavior he really tries to discourage others from attempting to recreate his feat （技藝表演），which has already been viewed more than 600，000since it was posted on January 26．
However，as a journalist pointed out，the past skateboarding events hosted on Kloof Nek have always taken place when all other traffic was closed off the street．He also said that local traffic laws don't permit skateboarders to skate on public roads．For his part，Lourenco，24，says he doesn't understand where all the negative attention is coming from．"I've been skating down hills from a young age…often going much faster than that，"he said in an interview with IOL News．"This is the first time I've got any attention for it．"But anyway，what he did is dangerous，and others shouldn't follow his example．

29．Decio Lourenco faces the charges mainly because heC．
A．caused motorists to panic on the street
B．broke the speed limit when he was driving
