19．甚至連科學(xué)家都還不能完全解釋動物在地震前的奇怪行為．
Even scientists cannot completelyaccountfor the strange behaviors of animals before an earthquake．

分析 account for

解答 答案：account for．
分析句子的結(jié)構(gòu)可知，本句缺少一個(gè)動詞短語用作謂語，表示"解釋，說明"，根據(jù)句意可知答案為account for．

點(diǎn)評 翻譯題在解題時(shí)首先要確定好句子的時(shí)態(tài)，然后要把握好短語表達(dá)，最后要注意句子結(jié)構(gòu)．

Dear Mr．Hush，
I have just learned over the radio that you feel as badly as I do about the way people use their cellphones．Very often in public place，people speak loudly on their cellphones，and we have to hearing about what is none of our business．So who cares about that？Not me!Why should I know life of people I don't even know？This is really nice that someone famous like you speak out for a quiet living space．
And it is even more wonderful to know about you yourself always talk quietly when using the cellphone in public．Thanks for not sharing that you are talking about．We had shared too much noise already!
A Person on Your Side．

10．Driving to the airport in the early morning，I felt excited．Although I was heading abroad for my first time alone，I felt cheerful and enthusiastic．I was spending the summer in Paris．
While looking for more interesting things to do besides sleeping and eating，I found programs for learning languages abroad，and jumped at the chance to study French in this city known for its art，fashion，food and culture．As I arrived at the airport where I would leave my family，I still felt only great happiness．I excitedly made my way through security，leaving my loved ones behind．
My connecting flight was in Frankfurt，Germany，14 hours from Denver．Sitting in a crowded plane watching bad movies couldn't dampen my excitement．When the woman next to me asked me where I was going，I happily answered and was pleased to note a tone of jealousy in her response．

4．See a cellphone cover that you like on Taobao？Forget about placing an order，paying the bill online and waiting for days for it to be delivered to you．In the near future，you'll be able to get it in minutes just by hitting"print"on your computer．
　  You might find it hard to believe that you could actually"print"an object like you would a picture．But it is not that hard to understand how it would work．Just as a traditional printer sprays （噴） ink onto paper line by line，modern 3D printers spread material onto a surface layer by layer，from the bottom to the top，gradually building up a shape．
　  Instead of ink，the materials the 3D printer uses are mainly plastic，resin（樹脂） and certain metals．The thinner each layer is-from a millimetre to less than the width of a hair-the smoother and finer the object will be．
　  This may sound like a completely new technology，but the truth is that 3D printing has been around since the late 1980s．Back then，it was barely affordable for most people，so few knew about it．
    Last year，though，saw a big change in the 3D printing industry-printers became much cheaper．For example，10 years ago a desktop 3D printer might have cost￡20，000，while now they cost only about￡1，000，accordin g to the BBC．
    Taken out of the factory and introduced to more diverse and common uses，3D printing can create just about anything you can think of-flutes （笛子），bikinis，jewelry，aircraft parts and even human organs．In fact，scientists from Cornell University in New York have just made an artificial ear using a 3D printer，according to Science Daily．The fake ear looks and acts exactly like a natural one．
    However，as 3D printing becomes more common，it may bring about certain problems-such as piracy．"Once you can download a coffee maker，or print out a new set of kitchen utensils （餐具） on your personal 3D printer，who will visit a retail （零售的） store again？"an expert in 3D printing told Forbes News．Even more frightening，what if anyone in the world could use a 3D printer to print out a fully functioning gun？
32．According to the article，in the future，the 3D printing technology willB．
A．enable people to make better purchases online
B．change the way we make many products
C．be applied as widely in our daily life as computers
D．shorten the time it takes for people to get what they buy online
33．What happened in the 3D printing industry last year？D
A．The 3D printing technology was taken out of the factory．
B．The 3D printing technology began to be used in various fields．
C．The 3D printer was used for medical treatment for the first time．
D．The 3D printer became more afforda ble for consumers．
34．How is the last paragraph developed？A
A．By giving examples．
B．By making comparisons．
C．By analyzing the cause and effect．
D．By presenting research findings．
35．What is the best title of the passage？D
A．Great Demand for 3D Printers　　         
B．Technology in the Future

8．What did you eat for lunch today？Did you choose this dish because it was healthy，cheap or because it was just very tasty？Are you a particular eater or an adventurous diner？
I love exploring trends in food．‘Fusion（融合） cuisine'is not for everybody．My Italian grandmother would turn her nose up in disgust at the thought of tandoori pizza with mango topping but this marriage of tastes is perfectly fine in the 21st century．Chef and food writer Ching-He Huang，who presented a series of Chinese Food for the BBC，is a fan of the movement．She says："Fusion has been happening for centuries，for as long as people have travelled，but with the Internet，and global travel，the exchange of ideas makes the process much faster．"
Wolfgang Puck is seen by many as one of the chefs who made‘fusion'elegant．He got his experience in this aspect in his native Vienna and made a name for himself when he opened his own restaurant in Los Angeles in the 1970s．This European dug into Asian cuisine and became one of the first in a long line of distinguished chefs．He said in an interview with the Wall Street Journal that initially he got negative responses from traditional American-Chinese restaurant owners but he is not bitter．"I believe authenticity is about evolution，not repeating your grandmoter's recipe．"he explains．"Cooking is like painting or writing a song．Just as there are only so many notes or colours．there are only so many flavours-it's how you combine them that sets you apart．"
My granny's cup of tea would be the Slow Food Movement．Founded by her countryman Carlo Petrini in the 1980s and still going strong，it seeks to preserve regional cuisine and the use of ingredients that are grown locally．Petrini wants to see farmers connected more directly with consumers．
All these trends give us food for thought．We might be wasting an exciting opportunity to wake up our taste buds when we swallow a sandwich at our desks．Tomorrow，why not find an exotic restaurant and enjoy a feast？You dress trendy so eat trendy!
28．Fusion cuisine isD．
A．a(chǎn) BBC cooking programme      
B．a(chǎn) balanced diet rich in nutrition
C．a(chǎn) new trend of global travelling   
D．a(chǎn) combination of different cooking styles
29．What do we learn about Wolfgang Puck？D
A．He knew little about Asian cuisine． 
B．He owed his success to his love for painting．
C．He was well received by Europeans．
D．He was in favor of creation in cooking．
30．The Slow Food MovementA．
A．a(chǎn)ims to keep alive local cuisine    
B．is favoured by old people
C．promotes local farming    
D．is founded by Granny
31．What can be a suitable title for the text？A
A．Hungry for new       
B．Greedy for tasty
C．Love for cooking

9．What would you like to be when you grow up？A teacher？A doctor？An astronaut？What do you need to do to achieve your dream job？Perhaps you think that studying well and then going on to work hard will get you successful career you want．We are constantly taught that our hard work will eventually pay off．
But a government survey has shown that hard work is not the only thing that will help you to move up the ladder．Two thirds of people believe that who you know matters more than what you know when it comes to social activity．So are the connections that you have more important than your education？
76% of the people in the survey believed that family background is important in influencing your chances of success．They believe that if you are privileged from birth，you are more likely to have a successful career，especially if your family is wealthy．
Even if you don't have a privileged background，the people you know can still make a difference to your career．Networking is a skill which is encouraged by many career advisers．Some companies run networking workshops to try and encourage staff to meet other people，to communicate and build relationships．It's a valuable skill．
But the survey also showed something quite interesting．Although most people believed that networks are more important than education，many people put their own career success down to talent，rather than background.41% of the people said that their parents'income had influenced their life，but at the same time，another 41% believed that they had achieved their own success．
So which is more important，what you know or who you know？It seems that by working hard and making lots of connections，the answer may be that both are very important．

21．According to the government survey，the most important factor to help people move up the ladder isB．
A．hard work   B．social relationship  C．education  D．social activity
22．Which of the following is NOT true according to the passage？A
A.76% of the people think social relationship is most important．
B.41% of the people believe parents'income is most important．
C.76% of the people think family background ranks first．
D.41% of the people believe they gained their own success．
23．From the passage we can infer that the writer writes the article toC．
A．stress the importance of education
B．make lots of social connections
C．challenge the traditional belief
D．encourage people to work hard．
24．Which of the following is the best title for the passage？D
A．A Survey on People's Dreams        B．Keep Your Dream in Mind
C．A Wealthy and Smooth Career        D．The Way to Success．
