5．My father and I stayed at the South Lake Hotel for a week when we visit Beijing last month．It is in the downtown area，but it is easy to go to anywhere from the hotel by public transport．
We lived in a comfortably doubleroom with a big bath．What I liked best were the free highspeed Internet connection in the room．I checked my email messages every day．I also shared for my friends many photos taking in Beijing．The food was wonderful with reasonable prices，and we enjoyed several local dish．
It is such great hotel that I would recommend it to any friend of me w ho is going to Beijing．

4．In our life，the fear of heights always（61）exists（exist） and it is a common feeling that is easy（62）to understand（understand）．It is one of only two natural fears and（63）theother is the fear of loud noises．Actually，having a fear of heights is good because it protects us（64）from/against real danger．
However，some people have an unreasonable and unhealthy fear of heights．They experience strong fears even inside a safe environment such as a tall building，（65）whichis not a common response and it is not helpful．（66）Fortunately（fortunate），this can（67）be treated（treat）．There are many ways as follows．
The most efficient way seems to make the people know（68）their（they） fear，for example，by encouraging them to go to the top of tall buildings．
Another way to overcome the fear is to learn to control the physical symptoms．When （69）faced（face） with a th reatening situation，one can take slow，deep breaths．If possible，a few minutes of deep thinking may be（70）effective（effect） in reducing tension．In a word，the fear of heights can be dealt with．

3．What will power your house in the future？Nuclear，wind，or solar power？According to scientists at the Massachusetts Institute of Technology （MIT） in the US，it might be leaves-but artificial （人造的） ones．
Natural leaves are able to change sunlight and water into energy．It is known as photosynthesis （光合作用）．Now researchers have found a way to imitate this seemingly simple process．
The artificial leaf developed by Daniel Nocera and his colleagues at MIT can be seen as a special silicon chip with catalysts （催化剂）．Similar to natural leaves，it can split water into hydrogen and oxygen when put into a bucket of water．The hydrogen and oxygen gases are then stored in a fuel cell，which uses those two materials to produce electricity，located either on top of a house or beside the house．
Though the leaf is only about the shape f a poker card，scientists claimed that it is promising to be an inexpensive source of electricity in developing countries．"One can imagine villages in India and Africa not long from now purchasing an affordable basic power system based on this technology，"said Nocera at a conference of the American Chemical Society．
The artificial leaf is not a new idea．The first artificial leaf was invented in 1997but was too expensive and unstable for practical use．The new leaf，by contrast，is made of cheap materials，easy to use and highly stable．In laboratory studies，Nocera showed that an artificial leaf prototype （原型） could operate continuously for at least 45hours without a drop in activity．
The wonderful improvements come from Nocera's recent discovery of several powerful，new and inexpensive catalysts．These catalysts make the energy transformation inside the leaf more efficient with water and sunlight．Right now，the new leaf is about 10times more efficient at carrying out photosynthesis than a natural one．Besides，the device can run in whatever water is available；that is，it doesn't need pure water．This is important for some countries that don't have access to pure water．
With the goal to"make each home its own power station"and"give energy to the poor"，scientists believe tha the new technology could be widely used in developing countries，especially in India and rural China．

33．Which of the following orders correctly shows how the artificial leaf is used to produce eletricity？A

2．The extraordinary Eastgate Building in Harare，Zimbabwe's capital city，is said to be the only one in the world to use the same cooling and heating principles as the termite mound（白蚁堆）．
Architect Mick Pearce used precisely the same strategy when designing the Eastgate Building，which has no air-conditioning and almost no heating．The building-the country's largest commercial and shopping complex-uses less than 10% of the energy of a conventional building of its size．The Eastgate's owners saved 3.5millionona36million building because an air-conditioning equipment didn't have to be imported．
The complex is actually two buildings linked by bridges across a shady，glass-roofed atrium（天井） open to the air．Fans suck fresh air in from the atrium，blow it upstairs through hollow spaces under the floors and from there into each office through baseboard vents（通风口）．As it rises and warms，it is drawn out via ceiling vents and finally exists through forty-eight brick chimneys．
During summer's cool nights，big fans blow air through the building seven times an hour to cool the empty floors．By day，smaller fans blow two changes of air an hour through the building，to circulate the air which has been in contact with the cool floors．For winter days，there are small heaters in the vents．
This is all possible only because Harare i 1600feet above sea level，has cloudless skies，little dampness and rapid temperature changes-days as warm as 31℃commonly drop to 14℃at night．"You couldn't do this in New York，with its hot summers and cold winters，"Pearce said．
The engineering firm of Ove Arup&Partners monitors daily temperatures．It is found that the temperature of the building has generally stayed etween 23℃and 25℃，with the exception of the annual hot period just before the summer rains in October and three days in November，when a doorkeeper accidentally switched off the fans at night．And the air is fresh-far more so than in air-conditioned buildings，where up to 30% of the air is recycled．

29．Why was Eastgate cheaper to be built than a conventional building？B
A．It was designed in a smaller size．
B．No air conditioners were fixed in．
C．Its heating system was less advanced．
D．It used rather different building materials．
30．What does"it"refer to in Paragraph 3？A
A．Fresh air from outside．B．Heat in the building．
C．Hollow space．D．Baseboard vent．
31．Why would a building like Eastgate Not work efficiently in New York？D
A．New York has less clear skies as Harare．
B．Its dampness affects the circulation of air．
C．New York covers a larger area than Harare．
D．Its temperature changes seasonally rather than daily．
32．The data in the last paragraph suggests Eastgate's temperature control systemB．
A．allows a wide range of temperatures
B．functions well for most of the year
C．can recycle up to 30% of the air
D．works better in hot seasons．

1．New crime predicton software should reduce not only the murder rate，but the rate of other crimes．Developed by Richard Berk，a professor at the University of Pennsylvania，the software has already used in Baltimore and Philadelphia to predict which individuals on probation（缓刑） or parole（假释） are most likely to murder and to be murdered．
"When a person goes on probation or parole he is supervised（监督） by an officer．The question is‘what level of supervision is appropriate？'"said Berk．It used to be that parole officers used the person's criminal record，and their judgment to make decisions．
"This research replaces those seat-of-pants calculations，"he said．
Technology helps determine level of supervision．On average there is one murder for every 100，000people．Even among high-risk groups the murder rate is one in 100．Predicting such a rare event is very difficult，but advances in computer technology orks．
Years ago，the researchers made a dataset of more than 60，000various crimes．Using the software they developed，they found some much more likely to commit murder when paroled or probated．They could identify eight future murderers out of 100．
Berk's software examines roughly two dozen variables（可变因素），from criminal record to geographic location．The type of crimes，and more importantly，the age at which that crime was committedwere two of the most predictive variables．
"People assume that if someone murdered then they will murder in the future，"said Berk．"What really matters is what that person did as a young individual．Predicting future crimes sounds well．But we aren't anywhere near being able to do that．"
"Berk's scientific answer leaves policymakers with difficult questions．By labeling one group of people as high risk，and supervise them closely，there should be fewer murders，which the potential victims should be happy about．It also means that those high-risk individuals will be supervised more aggressively．For human rights advocates，that means punishing people who，most likely，will not commit a crime in the future，"said Bushway．"It comes down to a question of whether you would rather make these errors or those errors．"
25．The underlined words（in Para.3）probably meanA．
A．calculations based on subjective opinions
B．calculations based on widespread voting
C．calculations made by advanced technology
D．calculations based on serious considering
26．For 650people with crime records，how many potential murderers would the software find？C

B．the technology would not be widely accepted in the short term
C．whether a person murders or not largely decidd by his upbringing while young
D．if a person murdered when he was fifty，he is sure to murder again while on probation
28．Which would be the best title for the passage？D
A．Closely Supervise Potential Murders
B．Measures Taken to Prevent Criminal Behavior
C．Technology Revolutionizes Judges'Way of Working
D．Software is Developed to Predict Criminal Behavior．

20．Men are spending more and more time in the kitchen encouraged by celebrity （名人） chefs like Gordon Ramsay and Jamie Oliver，according to a report from Oxford University．
The effect of the celebrity role models，who have given cooking a ore manly picture，has combined with a more general drive towards sexual equality and men now spendmore than twice the amount of time preparing meals than they did in 1961．
According to the research by Prof．Jonatahn Gershny，who runs the Centre for Time Research at Oxford，men now spend more than half an hour a day cooking，up from just 12minutes a day in 1961．
Prof．Gershuny said，"The man in the kitchen is part of a much wider social trend．There has been 40years of sexual equality，but there is another 40years probably to come．"
Women，who a generation ago spent nearly two hours a day cooking，now spend just one hour and seven mnutes-a great fall，but they still spend far more time in the kitchen than men．
Some experts have named these men in aprons as"Gastrosexuals （men using cooking skills to impress friends）"，who have been inspired to pick up a kitchen knife by the success of Ramsay，Oliver as well as other male celebrity chefs such as Hugh Fearnley-Whittingstall，Marco Pierre White and Keith Floyd．
"I was married in 1974．When my father came to visit me a few weeks later，I was wearing an apron when I opened the door．He laughed，"said Prof．Gershuny．"That would never happen now．"
Two-thirds of adults say that they come together to share at least three times a week，even if it is not necessarily around a kitchen or dining room table．Prof．Gershuny pointed out that the family meal was now rarely eaten by all of its members around a table-with many"family meals"in fact taken on the sofa in the sitting room，and shared by family members．"The family meal has changed a lot，and few of us eat-as I did when I was a child-at least two meals a day together as a family．But it has survived in a different format．"

21．What is one reason behind the trend that men spend more time cooking than before？D
A．The improvement of coks'status．
B．The influence of popular female chefs．
C．The change of female's view on cooking．
D．The development of sexual equality campaign．
22．What does the author think about the time men and women spend on cooking？B
A．Men spend more time cooking than women nowadays．
B．Women spend much less time on cooking than before．
C．It will take 40years before men spend more time at the stove than women．
D．There is a sharp decline in the time men spend on cooking compared with 1961．
23．How did Prof．Gershuny see the family meal according to the passage？B
A．It has become a thing of the past．
B．It is very different from what it used to be．
C．It shouldn't be advocated in modern times．
D．It is beneficial to the stability of the family．
24．Which is the best title for the passage？C
A．The Changes of Family Meals
B．Equality between Men and Women
C．Cooking into a New Trend for Men
D．Cooking-a Thing of the Past for Women．

19．

When was the last time you had fun with your parents？Your parents are all busy during working days； during the weekends，you may want to hang out with them but they may have to work extra hours．
This is not uncommon．In China，both of the parents have their jobs．Most of the parents try their best to offer their children comfortable circumstances，but they seldom have time to stay with their children．A recent survey done in the US found that more than half of American parents spend less than three hours having fun with their children each week．
As the Daily Mail noted：Families are spending little quality time creating bonds and precious memories together during the week because of the demands of modern life．

18．On a Saturday morning earlier this September，the world got its first look at the Strati．This electric vehicle is unlike any other currently on the road．It rolls on four wheels，but its body and chassis（底盘） weren't built in a factory．Instead，Strati's designers used a technology called 3-D printing．It created those parts of the car in one piece，from the ground up．
"Compared to a typical vehicle on the road，the Strati definitely looks different，"says Greg Schroeder，a senior research engineer at the Center for Automotive Research in Ann Arbor，Mich．He did not work on the new car．His organization studies trends and changes in the auto industry．
It took 44 hours to print the new car at the International Manufacturing Technology Show in Chicago．Over the next few days，the car's designers installed additional parts．These included the car's engine，brakes and tires．Then，early on September 13，Jay Rogers climbed into the car，started its engine and drove the vehicle onto the street．Rogers helped found Local Motors．It's the Arizona-based company behind the Strati．Two weeks later，his team printed a second Strati，and just as fast，at a fair in New York City．
Justin Fishkin，a local Motors official，sees the Strati as a window into the future．Today，car buyers are limited in their choice of a vehicle．They can order only what car companies have already designed．But in the future，he says，you may be able to design your own car online and then get it printed to order．
Manufacturing experts say 3-D printing has begun to revolutionize how they make things．The technology has been around for decades．But these machines used to be so expensive that only large companies could afford them．In the last few years，though，that has changed．Many of the machines are now inexpensive enough for small companies-or even individuals-to own．Some local libraries make them available to the public．High Schools are beginning to use them in classrooms．Wide access to these printers means people can now design and print a wide variety of new things．
The car's printer is a one-of-a-kind device．
The technology behind the 3-D printer used in Chicago is an example of additive manufacturing．This process builds solid objects，slice by slice，from the bottom up．（"Strati"means layers，in Italian．） A mechanical arm moves a nozzle from one side to another，back and forth．As it moves，the nozzle deposits a liquid-often melted plastic or metal （but it could be food，concrete or even cells）-that quickly hardens or bonds to become solid or semi-solid．This creates a single，thin layer．Once a layer is complete，the printer starts depositing the next one．
"There's a lot of interest in 3-D printing in the auto industry，"says Schroeder．Right now，the technology is particularly useful for building models of cars or car parts．
To compete with current auto manufacturers，the 3-D printer would have to increase in a hurry，Schroeder says．By contrast，he notes，a Ford F-150pickup truck rolls off an assembly line at a rate of roughly one per minute．To print as many Stratis would require many more printers．Schroeder says he doesn't see 3-D printing soon taking over for such high-volume manufacturing．But，he adds，"Who knows what will happen in the long term？"
Scientists at Oak Ridge National Laboratory in Tennessee designed the 3-D printer used in Chicago．Lonnie Love，a research scientist at the lab，led the effort．
Additive manufacturing often is slow and expensive．It also may produce materials that are unreliable，Love says．So for two years，his team searched for ways to make 3-D printing better．They built new machines and tested them over and over．
All of that work paid off：their new machine is fast and uses less expensive material than earlier printers．In addition，it prints a plastic embedded with fibers of carbon to produce a stronger material．This helps ensure the material won't crack or break under pressure．

71．Which of the following statements about the first Strati is TRUE？B
A．It was born in a car factory in Chicago．
B．All parts of it were not made by using a technology called 3-D technology．
C．It is a pity that it has not run on the street so far．
D．Many senior research engineers worked on it，including Greg Schroeder．
72．What can we infer from Paragraph 5？D
A．Large companies are always rich enough to buy expensive things．
B．Now High Schools are beginning to use 3-D printers in classrooms．
C．Wide access to 3-D printers has made it possible for people to order novel things online．
D．High prices of new products can stop them from being used widely in the beginning．
73．What does the word"nozzle"in Paragraph 7possibly refer to？B
A．A single，thin layer．
B．A part of the 3-D printer．
C．A solid or semi-solid object．
D．A person who operates the machine．
74．Why did Lonnie Love make efforts to improve 3-D printing with his team？A
A．Because additive manufacturing might produce unreliable materials．
B．Because he just was interested in making new things．
C．Because he just wanted to build new machines and test them
D．Because additive manufacturing is always slow but inexpensive．
75．Which of the following can be the best title for this passage？D
A.3-D Printers Are Coming
B.3-D Printers Are Becoming Well-Known
C.3-D Printers Are Becoming Cheaper
D.3-D Printers Are Making Cars．

16．Good health is the most valuable thing a person can have but one cannot take good health for granted．It is important to remember that the body needs proper care in order to be healthy．There are three things that a person can do to help stay healthy，eating right food，getting enough sleep，and exercising regularly．
Proper nutrition（营养） is important for good health．Your body cannot work well unless it receives the proper kind"fuel"．Don't eat too much food with lots of sugar and fat．Eat plenty of foods high in protein（蛋白质），like meat，fish，eggs and nuts．Vegetables and fruits are very important because they provide necessary vitamins and minerals．However，don't overeat．It is not helpful to be overweight．
Getting the proper amount of sleep is also important．If you don't get enough sleep，you feel tired and easily get angry．You have no energy．Over a long period of time a little amount of sleep may even result in a change of personality（人的个性）．Be sure to allow yourself from
seven to nine hours of sleep each day．If you do，your body will feel strong and refreshed，and your mind will be sharp．
Finally，get plenty of exercise．Exercise makes the body stronger，strengthens the muscles（肌肉），and prevents you from gaining weight．It also improves your heart and lungs．If you follow a regular exercise program，you will probably increase your life-span（寿命）．Any kind of exercise is good．Most sports are good for keeping the body in good shape：basketball，swimming，bicycling，running and so on．Sports are not only good for your body，but they are enjoyable and interesting，too．
