6.Long ago,sailors sailed to faraway places without the ability to rely on modern instruments to lead the way.Still,many were able to sail across vast,uncharted oceans and arrive at their destinations safely.Why didn't more sailors get lost at sea?What kinds of equipment did they use to find their way?
In early sailing history,few maps were available.Sailors had to rely on memory and on written guides called pilot books.Pilot books offered sailors information about how long it took to get to certain ports and instructions about getting in and out of the ports.Pilot books did not offer much information about sailing far from land.
Later,sailors used maps,charts,and information from other explorers to plan their trips.Early maps and charts offered descriptions of islands and coastlines tht helped sailors navigate.Experienced sailors learned where harbors,fresh water,supplies,and riendly people might be found.They were also able to warn others about dangers.Some of the early navigation practices and equipment used on these ships proved to be quite trustworthy.Early sailors used a tool called the astrolabe (星盘) to figure out the positions of stars and the sun to determine their location.For centuries,sailors planned their routes,sailed,and recorded their progress using the North Star as their only reference.They also used patterns of wind and waves as directional clues.Even though ocean waves may look the same to inexperienced eyes,they have different shapes related to the depth of the ocean and their closeness to land.Sailors even found a way that clouds and seabirds could help them.
The sailors of yesterday relied heavily on their observations and studies of the sea.Although their techniques were simple,they were able to achieve great things during their adventures at sea.
28.According to the text,pilot booksA.
A.are maps charted by other sailors   
B.are guides written by other sailors
C.offer descriptions of islands and ports  
D.offer information about sailing far away
29.We know from the text that early explorers and sailorsD.
A.established the shipping network    
B.invented many modern sailing tools
C.could locate all the ports and islands  
D.shared information and offered warnings
30.What is Paragraph 4mainly about?D
A.How early sailors found their way.
B.The importance of early navigation.
C.The difficulty of sailing far from land.
D.What arly sailors found on their journeys.
31.What's the author's attitude towards the sailors of yesterday?C
A.Objective.
B.Sympathetic.
C.Praiseworthy.
D.Regretful.

分析 本文主要写了古代航海在没有现在技术的情况下寻到了各种航海的方法.

解答 28.A 细节理解题.根据文中句子Sailors had to rely on memory and on written guides called pilot books可见这种书是由其他的水手绘制的,所以答案选A.
29.D推理判断题.根据句子Experienced sailors learned where harbors,fresh water,supplies,and riendly people might be found.They were also able to warn others about dangers.可见有经验的水手的经验都是后人航海的借鉴,他们的这些东西都是共享的,所以答案选D.
30.D 主旨大意题.通过段落内容可知本段主要写了早期的水手在他们旅途中的各种发明,所以答案选D.
31.C 写作态度题.根据文章最后一段Although their techniques were simple,they were able to achieve great things during their adventures at sea.
尽管他们的技术很简单,但他们在海上冒险时却能实现伟大的成就,可以看出作者对于古代的航海是一种值得赞扬的,所以答案选C.

16.Welcome back to the hot topic of studying abroad!Last time,we talked about the general"soft-ware"needed to have a (61)successful(success)  studying experience overseas,(62)whichrefers to the ability to understand western culture,and problem solving skills when (63)facing(face)  critical situations,etc..
Now,1will dig deeper into the concept of software".Everyone is talking about culture shock nowa-days,but you may wonder what it actually (64)means(mean).Simply put:culture shock is the diffi-culty people may experience when being exposed and adjusting to a (65)remarkably (remarkable)  different new culture.Usually,people often go (66)throughfour distinct phases:the honeymoon phase,the ne-gotiation phase,the adjustment phase and the mastery phase.Culture shock can happen immediately upon your (67)arrival(arrive)  in the country.
For international students,perhaps the most direct impact of culture shock is the variety of accents,especially in multicultural countries (68)likethe U.S.Canada or Australia.There are two main reasons:Firstly,these countries have highly diversified groups of residents from different cultural (69)backgrounds(background).Secondly,there are many international students from all around the world every year studying in these countries,so you shouldn't be surprised (70)to find(find) all kinds of unfamiliar accents around the university campus.

17.When you consider what subject to study in college,chances are (48)that you and your parents will think what you can make out of it (49)after graduation.You will likely ask the question:"Can I find a well-paid job or find simply a job with a degree in this in the future?"
This consideration also influences students when they come to choose (50)between science and humanities(人文学科) at college.People generally believe that the humanities,(51)which include literature,history,cultural studies and philosophy,do not prepare students for a specific profession.Science subjects,(52)however,are considered professional courses that produce scientists,engineers and economists.
"I've decided to take finance as (53)my college major.My parents and I think this subject will help me get a good job or start a business,"said Huachen Yueru,17,(54)a science student at Wuxi No.1Senior High School.

14.Thousands of taxi drivers in Shenyang,Liaoning Province,reportedly blocked (阻碍) streets with their cars on Sunday in protest (抗议) against unlicensed (无执照的) cars using taxi-hiring apps (打车软件) and apps-based car rental (出租) companies providing passenger services,including high-end (高端的) cars.Although the drivers also complained about the withdrawal (退出) of the fuel subsidy (燃油补贴) by the authority (管理部门),their main complaint was to make the authority aware of the loss of business because of the rising number of Internet-based car service companies.
It is not yet clear how Shenyang will deal with the problem and whether it will declare (宣布) the services offered by market leaders such as Didi Dache,a taxi-hiring app provider backed (支持) by Tencent Holdings (腾讯控股),and Kuaidi Dache illegal.But Shanghai has set a rule to ban Didi Zhuanche,or car services offered by Didi Dache from December on.
On Wednesday,news came that Beijing will take measures to stop the illegal"taxi business"of private cars through the newly rising Internet apps,following the footsteps of Shanghai and Nanjing.
Such acts will cause a setback (挫折) to the car-hiring companies and investors.Just last month,Didi Dache got $700million fund (基金) from global investors,including Singapore state investment company Temasek Holdings,Russian investment company DST Global and Tencent.Besides,the market is uncertain that Kuaidi Dache is about to finish its latest round of funding after getting 800million from global investors.
Uncertain regulatory (监管),however,could affect the future of the Internet-based car-hiring services,which have become popular in most of China's big cities.To be fair,these companies'business model is anything but bad.For example,Didi Zhuanche works side by side with car rental companies to provide high-end car service mainly for business people through the Internet and mobile phone apps.
Every link in this business model chain has legal companies and services.Therefore,it is hard to define (下定义) it as illegal and ban it.
32.Why did taxi drivers in Shenyang block the streets with their cars?A
A.Because they wanted to make their main complaints known to the authority.
B.Because they wanted the authority to continue the fuel subsidy.
C.Because they wanted to be taught how to use the taxi-hiring apps.
D.Because they wanted to appeal to passengers not to hire the private cars.
33.The author's attitude to banning internet car-hiring service isC.
A.positive             
B.neutral             
C.negative              
D.unclear
34.We can learn from the passage thatD.
A.Shenyang has already forbidden apps-based car rental companies
B.Shanghai won't ban Didi Zhuanche
C.it is quite easy to picture the apps-based car rental companies illegal
D.some international investment companies have strong faith in the future of apps-based car rental companies
35.Where can the passage probably appear?C
A.In a textbook.
B.In a travel guidebook.
C.In a newspaper.
D.In a poster on the wall.

1.Scientists around the world have been studying the warming of waters in the Pacific Ocean known as El Nino.The appearance of El Nino is known to affect the weather around the world.Scientists still do not completely understand it.Yet they now find they can use it to tell about the future in different areas of the world.
One example is the work of two scientists at Columbia University in New York,Mark Cane and Gordon Eshel.A scientist of Zimbabwe(津巴布韦),Roger Buckland worked with them.They have found that when El Nino appears,Zimbabwe has little or no rain.This means corn crops in Zimbabwe are poor.The last El Nino was in 1991to 1993.That was when southeastern Africa suffered a serious lack of rain.
The scientists wrote about their recent work in the publication Nature.Their computer program can tell when an El Nino will develop up to a year before it does.They suggest that this could provide an effective early warning system for southern Africa,and could prevent many people from starving.
33.El Nino is known asB.
A.the changing of the weather in southern Africa
B.the warming of waters in the Pacific Ocean
C.the weather which brings drought(旱灾)to Africa
D.the weather phenomenon that brings heavy rains to Africa
34.Scientists study El Nino in order thatA.
A.they can provide a kind of early warning to the place that will suffer from drought
B.they can tell why Zimbabwe has little or no rain
C.they can do some research work in this field.
D.they can put all this information into their computers.
35.Which of the following is TRUE according to the passage?D
A.Scientists come to understand how El Nino appears.
B.Three scientists from the USA work on this subject.
C.Southern Africa suffered a serious drought and many people died from hunger.
D.El Nino has something to do with Zimbabwe's poor crops.

11.I would like to suggest that for sixty minutes each evening,right after the early evening news,all television broadcasting be banned by law.
Let us take a serious look at what the results might be if such a suggestion were accepted.Families might use the time for a real family hour.They might sit around together after dinner and actually talk to one another.It is well known that many of our problems-everything,in fact,from the generation gap(代沟) to the high divorce rate to some forms of mental illnesses-are caused at least in part by the failure to communicate.We do not tell each other what is disturbing us.The result is emotional difficulty of one kind or another.By using the quiet family hour to discuss our problems,we might get to know each other better,and to like each other better.
On evenings when such talk is unnecessary,families could rediscover more active entertainments.Freed from TV,forced to find their own activities,they might take a ride together to watch the sunset.Or they might take a walk together and see the neighborhood with fresh,new eyes.
With free time and no TV,children and adults might rediscover reading.There is more entertainment in a good book than in a month of typical TV programming.Educators report that the generation growing up with television can hardly write an English sentence,even at the college level.Writing is often learned from reading.A more cultured new generation could be a product of the quiet hour.
At first glance,the idea of an hour without TV seems radical (激进的).What will parents do without the electronic baby-sitter?How will we spend the time?But it's not radical at all.It has been only twenty-five years since television came to control our free time.Those of us thirty-five and older can remember childhoods without television,spent partly with radio-which at least involved the listener's imagination-but also with reading,learning,talking,playing games and inventing new activities.It wasn't that difficult,honest.The truth is that we had a ball.
28.The author's suggestion can helpA.
A.people solve emotional problems
B.draw people's attention to the evening news
C.college students get along well with others
D.develop strong neighborhood relationships
29.According to the text,good booksB.
A.offer as much knowledge as TV does   
B.are more entertaining than TV
C.should be made into films            
D.cannot be found easily
30.In the author's opinion,life without TVC.
A.is not good for children's imagination   
B.will be accepted by more people
C.used to be a lot of fun                
D.is not worth living
31.What would be the best title for the text?B
A.The future of television   
B.Turning off TV:a quiet hour
C.Saying goodbye to television   
D.Effects of television on humans.

16.Sleeping in on Saturday after a few weeks of too little shuteye may feel refreshing,but it can give a false sense of security.
New research shows long-term sleep loss cannot be cured that easily.Scientists researched the effects of short-and long-term sleep loss and found that those who suffer long-term sleep loss may function normally soon after waking up,but experience steadily slower reaction times as the day goes by,even if they had tried to catch up the previous night.
The research has important safety significances in an increasingly busy society,not just for shift-workers but for the roughly one in six Americans who regularly get six hours or less of sleep a night.
"We know that staying awake 24 hours without sleep will affect your performance to do all sorts of things,and this effect equals to drinking too much when driving,"said lead researcher Dr.Daniel Cohen of Boston's Brigham and Women's Hospital.But when those who suffer long-term sleep loss become all-nighters,"the harm is increased ten times,"Cohen said.
The National Institutes of Health says adults need seven hours to nine hours of sleep for good health.Regularly getting too little sleep increases the risk of health problems,including memory impairment and a weakened immune system.More immediately,too little sleep affects reaction times; sleepiness is to blame for car crashes and other accidents.
It has critically important complicated and unexpected results for anyone who works"crazy hours"and thinks they are performing fine with a few hours of weeknight sleep,said Harris,director at New York's Montefiore Medical Center."Don't think you can just bank up your sleep on the weekend,because it doesn't work that way,"he warned.
61.The text mainly advises peopleC.
A.to sleep more time                         
B.to sleep in on Saturday
C.to sleep scientifically                     
D.to sleep little on weekend
62.People with long-term sleep lossB.
A.are quicker in thinking                   
B.may feel refreshed soon after waking up
C.are surely energetic                        
D.can have a strong sense of security
63.What can we learn from the text?B
A.Most of the Americans get six hours or less of sleep a night.
B.Staying up is worse for those who suffer long-term sleep loss.
C.Traffic accidents have little to do with sleepiness.
D.One in six Americans are all-nighters.
64.Which of the following is the immediate effect of long-term sleep loss?C
A.Health problems                            
B.Immune system
C.Reaction times                              
D.Memory impairment
65.The underlined phrase"bank up"in the last paragraph most probably meansA.
A.pile up      B.pick up      C.add up               D.build up.
