Text 8 Hello,everyone.It is indeed a great pleasure to have this chance to address such a large audience this evening. I'm Pierre Chabreau from the University of Marseille.At the moment,I'm carrying out research in Senegal for the United Nations,as part of a project to increase world food production.Before I get on to what exactly we did in our research,I would like to explain briefly the purpose behind it.Quite simply,my subject is rice.As you all know,rice is the main food for millions of people in the world.So,if rice crops fail,millions of people starve and die.And they do fail,very often through disease.Now,what my col- leagues and I have been doing out in the field in Senegal, as well as in the university laboratories,is to try to produce a disease-resisting variety of rice-a particular kind of rice which will resist disease...in other words,a stronger type of rice. Text 9 W:Now,let me show you around our school.This is our computer lab. M:Wow！So many computers！How many computers do you have?

Tan Yunxian (1461-1554)was a Chi- nese physician who learned her skills from her grandparents.Chinese women at the time could not serve apprenticeships(学徒期)with doc- tors.However,Tan passed the official exam. Tan treated women from all walks of life.In 1511,Tan wrote a book,Sayings of a Female Doctor,describing her life as a physician. James Barry (c.1789-1865)was born in Margaret Bulkley in Ireland,but,dressed as a man,she was accepted by Edinburgh University to study medicine.She qualified as a surgeon in 1813,then joined the British Army,serving overseas.Barry retired in 1859,having practiced her entire medical profession living and working as a man Rebecca Lee Crumpler 1831-1895 worked as a nurse for eight years before studying in medical college in Boston in 1860.

B The Indian government may use 3D paintings as virtual speed breakers on major highways and roads,in an attempt to check speeding and careless driving,and eventually make its deadly roads a little safer."We are trying out 3D paintings used as virtual speed breakers to avoid unnecessary requirements of speed breakers,"India's transport minister Nitin Gadkari tweeted. The visual illusions(幻象)are supposed to encourage drivers to slow down automatica- lly.Earlier this month,India had ordered the removal of all speed breakers from highways, which are considered to be a danger to safety for high-speed vehicles. India has the highest number of road accident deaths in the world.According to the World Health Organization,over 200,000 peo- ple are killed by road accidents due to poor application of road safety laws.This is considerably higher than its official figures of 141,526for2014. The use of visual illusions as speed brea- 23 N 高中英语必修第三册（外研版） kers was first pioneered in the American city of Philadelphia in 2008,as part of a campaign against speeding motorists.The technique has also been tried out in China to create floating 3D crossings. In India,cities such as Ahmedabad and Chennai have already experimented with 3D zebra crossings in the last one year.In Ahmedabad,for instance,two artists,mother and daughter have painted 3D crosswalks in the first few months of this year.The artists say their motto is "to increase the attention of drivers",and that the concept has been suc- cessfully tested in zones where accidents easily occur on a highway. However,critics argue that once drivers know that these speed breakers are visual illusions,they may ignore them.Others also point out that India's decision does not consider the safety of a large number of walkers.In the end,the new policy may be just one step towards improving road safety. 24.According to the passage,3D paintings as virtual speed breakers in India aims to A.replace all speed breakers from highways B.encourage essential requirements of speed breakers C.check speeding and careless driving on all highways D.remind drivers to speed down voluntarily for road safety 25.What caused the high number of road acci- 24 dent deaths in India? A.Speeding motorists. B.Floating 3D crossings. C.Free use of visual illusions. D.Bad application of traffic laws. 26.The author explains the experiment of 3D zebra crossings in India by. A.giving examples B.analyzing causes C.providing figures D.making comparisons 27.What's the author's attitude towards 3D zebra crossings? A.Subjective. B.Objective. C.Supportive D.Critical. C We humans love to stare into our smart devices.We gaze for hours-about 10 hours and 39 minutes a day-at our computers, smartphones,tablets and televisions.Is all this staring bad for us?It might be mainly because as we stare at our devices we are exposing ourselves to blue light. Blue light is a type of electromagnetic (电磁的)radiation with a very short wave- length that produces a high amount of energy. While it's true that light can damage our eyes under certain circumstances,there's no scientific evidence suggesting that blue light is harmful to our eyes.But many people still think it is,which is why blue-light-blocking glasses are so popular.So do the glasses work? "Everyone is very concerned that blue light may be causing damage to the eye,but there's no evidence that it may be causing serious damage,"Dr.Rahul Khurana,clinical spokesman for the American Academy of Ophthalmology,told Business Insider. Blue light exposure is nothing new.In fact,the sun is the largest source of blue light. Moreover,blue light is also present in LED light.But if blue light isn't harmful,then why are we constantly rubbing our eyes when we're looking at our screens?The answer is eyestrain(眼疲劳)：More than60 percent of people experience eye problems associated with digital eyestrain.And blue light,it seems, isn't the cause.Instead,our eyes are so strained because most of us blink less when we stare at our digital devices.So if eyestrain is the issue,blue-light-blocking glasses are probably of little use. 28.What do we know about blue light? A.It is a kind of nuclear radiation. B.It has the shortest wavelength. C.It may come from electronic devices. D.It consumes a great deal of energy. 29.What causes the popularity of blue-light- blocking glasses? A.Evidence of their benefits to eyes. B.Belief in blue light's harmful effect. C.Widespread use of smart devices. D.Scientific understanding of blue light. Unt3单元测试卷。 30.What can be inferred from Paragraph 4? A.Blue light exposure is hardly avoidable. B.Eye problems are not easy to deal with. C.Blue light may connect with tired eyes. D.Rubbing eyes makes people strained. 31.According to the text,wearing blue-light- blocking glasses may be. A.tiring B.harmful C.useless D.beneficial D For people,who are interested in sound, the field of sound technology is definitely making noise.In the past,sound engineers worked in the back rooms of recording studios, but many of today's sound professionals are sharing their knowledge and experience with professionals in other fields to create new products based on the phenomenon we call sound. Sound can be used as a weapon.Imagine that a police officer is chasing a thief.The thief tries to escape.And the officer can't let him get away.He pulls out a special device, points it at the suspect,and switches it on.The thief drops to the ground.This new weapon is called a Long Range Acoustic Device (LRAD,远程定向声波发射器).It produces a deafening sound so painful that it temporarily disables a person.The noise from the LRAD is directed like a ray of light and travels only into the ears of that person,but it is not 25 N 高中英语必修第三册（外研版） deadly. For those who hunger for some peace and quiet,sound can now create silence.Let's say you are at the airport,and the little boy on the seat next to you is humming(哼唱)a short commercial song.He hums it over and over again,and you are about to go crazy.Thanks to the Silence Machine,a British invention, you can get rid of the sound without upsetting the boy or his parents.One may wonder how the Silence Machine works.Well,it functions by analyzing the waves of the incoming sound and creating a second set of outgoing waves. The two sets of waves cancel each other out. Simply turn the machine or point it at the target,and your peace and quiet comes back. Directed sound is a new technology that allows companies to use sound in much the same way spotlights(聚光灯)are used in the theater.A spotlight lights up only one section of a stage;similarly,a“spotsound”creates a circle of sound in one targeted area.This can be useful for businesses such as restaurants and stores because it offers a new way to attract customers.Restaurants can offer a choice of music along with the various food choices on the menu,allowing customers more control over the atmosphere in which they are dining.Directed sound is also beginning to appear in shopping centers and even at homes. 32.What could be inferred from Paragraph 2 about the effect of the LRAD? A.It causes temporary hearing loss. 26 B.It slows down a running man. C.It makes it easy to identify a suspect. D.It keeps the suspect from hurting others. 33.What is the Silence Machine specially de- signed for? A.To silence the people around you. B.To remove the sound of commercials. C.To block the incoming sound waves. D.To stop unwanted sound from affecting you. 34.What feature do spotsounds and spotlights share? A.They travel in circles. B.They clear the atmosphere. C.They can be transformed into energy. D.They can be directed onto a specific area 35.What does the passage focus on? A.How professionals invented sound pro- ducts. B.Inventions in the field of sound techno- logy. C.The growing interest in the study of sound. D.How sound engineers work in their studios. 第二节（共5小题；每小题2.5分，满分 12.5分) 阅读下面短文，从短文后的选项中选出 可以填入空白处的最佳选项。选项中有两项 为多余选项。 Sarah Hutchins has won a prize from Amazon.com in a competition for young inventors.She invented“camoculars'！Now what are "camoculars"?Camoculars are bi- noculars(双筒望远镜)and a camera combined. Amazon.com,a web company,organized a competition for young inventors.36.

In 1988,Bert and John took a seven- week road trip from California to Boston.The brothers said this trip changed their lives forever as they looked back on their childhood.According to the Jacobs,their childhood was perfectly-imperfect.Their house did not have heating but they were taught to 29 N 高中英语必修第三册（外研版） always see the good in things. They remembered playing outside all day and when it was dinner time,they would gather around the dinner table.Their mother would say to them,"Tell me something good that happened today."Their father had a near- death accident which caused severe damage to his right hand.The accident made their father develop a terrible temper(脾气)，but their mother would always sing to them and read them children's stories."That optimism was something our family always had,even when we had little else,"the brothers said. During the trip,they tried to figure out what they wanted to do with their lives and decided to run a clothing business.They started selling T-shirt designs in street fairs around Boston.Their design was just a simple drawing of a stick figure with the phrase “Life is good”. Their small business didn't turn out so well,but the two brothers did not give up. Then they changed their target audience.This time,they tried to sell their T-shirts to college students,going to different schools every night.Again it did not work.To figure out what they had been doing wrong,Bert and John held beer parties,where they asked their friends for their honest opinions.In return, they could enjoy free beer and amusing stories from the brothers.Again this did not seem to work and they were running out of money. 30 注意： (1)续写词数应为150个左右； (2)请按如下格式在相应位置作答。 Paragraph 1: However,they took the risk and held another party which they thought was the last.
