4.Google Glass,a wearable computer,will not go on sale for many months.But the resistance is already under way.The glasses-like device,which allows users to access the Internet,take photos and shoot videos,has been banned by a bar in Seattle,because according to the bar'owner,the bar was"kind of a private place."Besides,large parts of Las Vegas will not welcome wearers.
Google Glass is a pair of glasses with a tiny computer attached to the right earpiece and has the ability to capture any chance encounter and broadcast it to millions.As personal technology becomes increasingly invisible,it is causing questions of whether it will rob people of privacy.
As Google sees it,Glass is a revolutionary new way to quickly and effortlessly connect people with information.Google stresses that Glass is a work in its early stage,with test versions now being released to 2,000developers.The company hopes they'll be seen as normal and become accepted in the same way smart phones are.The wearer has to speak or touch the device to activate(激活) it,and must look directly at someone to take a photograph or video of them."We are thinking very carefully about how we design Glass because new technology always raises new issues,"said Courtney Hohne,a Google spokeswoman.
Critics view Glass as an unfriendly new technology that could rob people of what few privacy they have left.They think Google is downplaying the privacy and security risks.According to Google,it's obvious when someone is taking pictures or recording a video on Glass.Developers,however,are pushing the limits.One created a small sensation in tech circles with a program that eliminated the need for gestures or voice commands.To snap a picture,all the user needed to do was wink(眨眼).
Imagine a surveillance(监控) device that you could wear on your body all day without anyone being the wiser.Out on the street,in the subway,at a bar or cafe,people would never know whether the stranger next to them is secretly recording their every move.It is really a privacy disaster.

41.What can we know from the first paragraph?D
A.Google Glass sells well in the market.
B.Google Glass is not welcomed by customers.
C.Google Glass can not be used in private places.
D.Google Glass has heard some sort of disapproval.

A.Google Glass is an immature product.
B.They are acting cautiously in designing Google Glass.
C.People can take photos without eyeing the objects.
D.Google Glass is just as normal as a smart phone.
43.The underlined part"pushing the limits"in Paragraph 4refers toB.
A.speeding up the production time of Google Glass
B.improving the functions of Google Glass

A.Google glass is not worth buying
B.people are constantly monitored
C.people can become wiser with Google Glass

点评 1、要想做好科普英语阅读理解题,同学们就要注意平时多读科普知识类文章,学习科普知识,积累常见的科普词汇,从根本上提高科普英语的阅读能力.
2、要熟悉科普类文章的结构特点.科普类文章一般由标题(Head line),导语(Introduction),背景(Back ground),主体(Main body)和结尾(End)五部分构成.标题是文章中心思想高度而又精辟的概括,但根据历年的高考情况来看,这类阅读理解材料一般不给标题,而要同学们选择标题.导语一般位于整篇文章的首段.背景交待一个事实的起因.主体则对导语概括的事实进行详细叙述,这一部分命题往往最多,因此,阅读时,同学们要把这部分作为重点.结尾往往也是中心思想的概括,并与导语相呼应,命题者常在此要设计一道推理判断题.  
3、在进行推理判断时,同学们一定要以阅读材料所提供的科学事实为依据,同时所得出的结论还应符合基本的科普常识.

15.Students from Florida International University in.Miami walked on water Thursday for a class assignment.To do it,they wore aquatic (水上的)shoes they designed and created.
Alex Quinones was the first to make it to the other side of a 175-foot lake on campus in record time-just over a minute.Quinones,who wore oversized boat-like shoes,also won last year and will receive  500.Students had to wear the aquatic shoes and make it across the lake in order to earn an'6A"on the assignment for Architecture Professor Jaime Canaves,Materials and Methods Construction Class."It's traditional in a school of architecture to do boats out of cardboard for a boat race.I thought our students were a little bit more special than that,"Canaves said."We decided to do the walk on water event to take it to the next level."

A large crowd on campus joined Canaves as he cheered on the racers.He shouted encouraging words,but also laughed as some unsteadily made their way to the end.
"A part of this is for them to have more understanding of designing and make it work better,"he said.It is also a lesson in life for the students.

12.A dog's tail can tell you a lot more than you might think.Is it wagging(摇)to the left or is it wagging to the right?
"The direction of tail wagging does in fact matter,"said Giorgio Vallortigara,a professor at the University of Trento in Italy.Professor Vallortigara finds that the way the tail is wagging can tell you a lot about a dog's state of mind-whether you're a human or another dog.
What's the difference between a left wag and a   right wag?Professor Vallortigara and his colleagues have studied 43 dogs of various breeds-German Shepherds,Beagles,Boxers,Border Collies and some mutts.They find that if a dog wags its tail to the left,it's feeling anxious or nervous.The reason could be an unfamiliar or dangerous situation,an unfamiliar person,or an unfamiliar and possibly threatening dog.But if the tail is wagging to the right,it means the dog is feeling relaxed and approachable.
"The tail is a very important signal,"said Thomas Reimchen,a biologist at the University of Victoria in British Columbia,Canada."There is a lot of visual information that dogs use when communicating with each other."
How did the scientists figure all this information out?They had the dogs in their study watch videotapes of other dogs.When the dog on the tape wagged its tail to the right,they say the other dogs remained calm and cool.But when the dog on the tape wagged its tail to the left,the other dogs got anxious.
The researchers are still not exactly sure if the direction of tail wagging is something the dog does consciously.They suspect that it might be something the dog does without even thinking about it-kind of like when you get goose bumps if something scares or startles you.They plan to do more research to get more information about what dogs are thinking and feeling while they're wagging.As Reimchen said,"I'm not going to be surprised if we find all sorts of really interesting processes that nobody has ever seen before."
 
64.Professor Vallortigara'study focused on the relationship betweenB.
A.a dog's state of mind and its owner's feeling
B.a dog's state of mind and the direction of its tail wagging
C.a dog's sense of direction and its state of mind
D.a dog's intention of tail wagging and its feeling      
65.According to the study,dogs which wag their tails to the left may feelD.
A.calm        B.happy         C.angry         D.anxious
66.It is implied in Thomas Reimchen's words in Paragraph 4 thatC.
A.dogs'tails play an important role in their growth
B.dogs show their feelings only by wagging their tails
C.dogs get to know others by watching tail wagging 
D.dogs can understand each other by repeating tail wagging
67.How does the passage mainly develop?A
A.By asking and analyzing questions       
B.By making comparisons.
C.By following the order of time.
D.By providing examples.
