Quickly, the picture comes alive with hyperlinks (超链接), offering the names of the buildings, towers and street features that appear in the photo.The hyperlinks lead to information about the history, services and context of all the features in the photo.You have just hyperlinked your reality.
That might be a little unbelievable, but the technology exists and is no fevered imagination.This is not a cool small machine invented for the next James Bond movie; this is a working technology just developed by European researchers.It could be coming to a phone near you, and soon.
This, as the marketing types say, is a game changer.It develops a completely new interface (界面) that combines webtechnology with the real world.It is big and fresh, but it goes much further and has much greater influence.
The development of the system is most outstanding because image recognition technology has long been pregnant with promise, but seemed to suffer from an unending labour.
Now MOBVIS has not only developed image recognition; it has also developed more applications for the technology; and it has adapted it to the world's most popular technology: the mobile phone.
The MOBVIS system completely rewrites the rules for exploration and interaction with your physical environment.The system begins with panoramas (一连串景象)．These panoramas form the basis of a city database.It can match buildings, towers, banners and even logos that appear in the panoramas. A user simply takes a picture of the street feature, MOBVIS compares the user's photograph to the panoramas and then identifies the buildings from the picture you take and the relevant links are returned.
Then you simply click on the links, using a touchscreen phone, and the MOBVIS system will provide information on the history, art, architecture or even the menu, if it is a restaurant, of the building in question.
16．Which is introduced in the passage?
A．A new game software.
B．A popular mobile phone.
C．A cool small machine.
D．An image recognition system.
17．What can we learn about the new technology?
A．It can only be put into use on mobile phones.
B．It is a little unbelievable and just a fevered imagination.
C．It has taken an unending labour to bring the technology into our lives.
D．It will encourage the users to take more pictures of the street features.
18．What is the right order of the operation of MOBVIS?
a．A city database forms in the system.
b．MOBVIS recognizes the picture and links are returned.
c．A user touches the links on the phone screen.
d．A user takes a picture of the street feature.

John Thornton had been ill in December，and his two friends had had to leave him at White River and go on to Dawson.They left him in the camp with plenty of food，and with his two dogs，Skeet and Blackie.Now the spring had come，and he was almost well.He lay in the sun by the river with Buck，watching the water and listening to the birds，slowly getting stronger and stronger.
A rest is very welcome after running five thousand kilometres，and Buck slowly got fatter and stronger.It was a peaceful，lazy time for both man and dogs while they waited for Thornton's friends to return from Dawson.
Skeet made friends with Buck immediately，and while Buck was still very ill, every morning she washed his cuts carefully with her tongue.Blackie，too，was friendly，and as Buck grew stronger，the three dogs often played games together.Sometimes Thornton joined the games too.
The days passed very happily，and for the first time，Buck learned to love.He had never loved a man before.He and Mr Miller in the Santa Clara valley had been very good friends，but Buck had not loved him.John Thornton had saved his life，but he was also a man who was naturally kind to animals.He took very good care of his dogs，not because it was sensible to do that, but because he felt they were his children. He was always talking to Buck，holding his head and shaking it lovingly.In answer，Buck liked to take Thornton's hand gently in his mouth.
Buck was happy to lie on the ground all day and watch Thornton and when Thornton spoke to him or touched him，Buck went wild with happiness. At first, he was afraid that Thornton was going to disappear，like Perrault and Francois，and at night he sometimes woke up and went to the tent to make sure that he was still there.
But something was changing in Buck.He had lived in the north a long time now，and he was almost a wild dog.He was happy to sit by Thornton's fire，but he sat as a wild animal，and his dreams were filled with other animals—dogs, half wolves，and wild wolves.They seemed to call him into the forest，and sometimes Buck wanted to leave the fire and answer the call.But every time he went into the trees，his love for Thornton brought him back.
It was only Thornton who stopped him going into the forest.Other men did not interest him.Visitors to the camp tried to make friends with him，but Buck stayed cold.When Thornton's two friends，Hans and Pete，arrived from Dawson，Buck refused to notice them at first.Then he saw that they were friends of Thornton's and after that he accepted them；but they were not his friends.They were，like Thornton，kind men，and they understood that Buck loved Thornton，and him alone.
It happened in the autumn in Circle City.A man called Burton was starting a fight with another man in a bar.Thornton stepped between them to try to stop them.Buck was，as usual，lying in the corner watching.Burton hit Thornton and he nearly fell，just catching a table.Buck flew through the air at Burton's throat.Burton saved his life by putting up his arm，and was thrown on to the ground，with Buck on top of him.Buck took his teeth out of the man's arm and this time bit into his throat.Then a crowd of people pulled Buck off，and a doctor was called.Everyone agreed that Buck had only attacked because he saw Thornton in danger，and from that day Buck's name became famous all over the north.
Later that year，Buck saved Thornton in a different way.

课时作业(三十八)
Ⅰ.1.D 考查非谓语动词。非谓语动词作定语时，其中心词是被修饰的词。该题中seat是一个及物动词，且和person之间是被动关系，故用过去分词作定语。
2．B 考查非谓语动词。be employed in doing sth.忙着做某事，固定短语。
3．B 考查非谓语动词。这里表示(我)回首过去，用现在分词。句意：回首过去，我可以看到过去那些可怕的事情把我塑造成了今天的我。
4．C 考查非谓语动词。原句补充完整为：Mao Zedong compare the youth to the rising sun at 8 or 9 a. m．，he…；主谓之间是主动关系，故用现在分词。
5．B 考查非谓语动词。be surrounded with由……环绕。surrounded with a high wall and thick trees＝which is surrounded with a high wall and thick trees，这里是过去分词短语作后置定语。
6．A 考查介词短语辨析。out of order出故障了，可根据“你必须让人检查一下”判断。out of control失去控制，不符合句意。
7．D 考查短语辨析。now and then意为“有时，偶尔”。句意：两年前安娜离开家乡以来我就没见过她，但我们的确有时发电子邮件保持联系。here and there到处；sooner or later迟早；at one time一度，曾经。
8．D 考查形容词辨析。be convenient for是一个固定短语，意为“对……来说做某事是方便的”。
9．B 考查非谓语动词。分词短语作非限制性定语，排除A；逻辑主语the performance与intend是被动关系，故用过去分词。

11．D 考查状语从句。in case，for fear that引导目的状语从句词义为“以防……，以免……”。须指出的是in case引导的从句，谓语动词用一般现在时表示将来时。for fear that其从句谓语动词前需有may，might，will或would等情态动词。
12．B 考查非谓语动词。动词bear后跟动名词形式作宾语；且此处哭的原因是无法忍受“被取笑”，he和make fun of之间为被动关系，故应该用过去分词形式。
13．C 考查动词的时态。by the time 后的从句多用一般现在时和一般过去时。根据该题的语境可以断定答案为C。
14．A 考查倒装。nowhere置于句首时，要用部分倒装结构。根据句意应是“到现在你也不能在什么地方看到这样美丽的宫殿，”所以用一般现在时，故选A。
