Just how much does the Constitution protect your digital data?The Supreme Court will now consider whether police can search the contents of a mobile phone without a warrant if the phone is on or around a person during an arrest.California has asked the justices to refrain from a sweeping ruling particularly one that upsets the old assumption that authorities may search through the possessions of suspects at the time of their arrest.It is hard,the state argues,for judges to assess the implications of new and rapidly changing technologies.The court would be recklessly modest if it followed California’s advice.Enough of the implications are discernable,even obvious,so that the justices can and should provide updated guidelines to police,lawyers and defendants.They should start by discarding California’s lame argument that exploring the contents of a smart phone—a vast storehouse of digital information—is similar to,say,rifling through a suspect’s purse.The court has ruled that police don’t violate the Fourth Amendment when they sift through the wallet or pocketbook of an arrestee without a warrant.But exploring one’s smart phone is more like entering his or her home.A smart phone may contain an arrestee’s reading history,financial history,medical history and comprehensive records of recent correspondence.The development of“cloud computing,”meanwhile,has made that exploration so much the easier.Americans should take steps to protect their digital privacy.But keeping sensitive information on these devices is increasingly a requirement of normal life.Citizens still have a right to expect private documents to remain private and protected by the Constitution’s prohibition on unreasonable searches.As so often is the case,stating that principle doesn’t ease the challenge of line-drawing.In many cases,it would not be overly onerous for authorities to obtain a warrant to search through phone contents.They could still invalidate Fourth Amendment protections when facing severe,urgent circumstances,and they could take reasonable measures to ensure that phone data are not erased or altered while a warrant is pending.The court,though,may want to allow room for police to cite situations where they are entitled to more freedom.But the justices should not swallow California’s argument whole.New,disruptive technology sometimes demands novel applications of the Constitution’s protections.Orin Kerr,a law professor,compares the explosion and accessibility of digital information in the 21st century with the establishment of automobile use as a virtual necessity of life in the 20th:The justices had to specify novel rules for the new personal domain of the passenger car then;they must sort out how the Fourth Amendment applies to digital information now.

Cell Phones: Hang Up or Keep Talking?
Millions of people are using cell phones today.In many places it is actually considered unusual not to
use one.In many countries,cell phones are very popular with young people.They find that the phones are
more than a means of communication一having a mobile phone shows that they are cool and connected.
The explosions around the world in mobile phone use make some health professionals worried.Some
doctors are concerned that in the future many people may suffer health problems from the use of mobile
phones.In England,there has been a serious debate about this issue.Mobile phone companies are worried
about the negative publicity of such ideas.They say that there is no proof that mobile phones are bad for your
health.
On the other hand,why do some medical studies show changes in the brain cells of some people who use
mobile phones?Signs of change in the tissues of the brain and head can be detected with modern scanning
（扫描）equipment. In one case , a traveling salesman had to, retire at a young age because of serious memory
loss.He couldn't remember even simple tasks.He would often forget the name of his own son.This man
used to talk on his mobile phone for about six hours a day,every day of his working week,for a couple of
years.His family doctor blamed his mobile phone use,but his employer's doctor didn't agree.
What is it that makes mobile phones potentially harmful?The answer is radiation.High-tech machines
can detect very small amounts of radiation from mobile phones.Mobile phone companies agree that there is
some radiation,but they say the amount is too small to worry about.
As the discussion about their safety continues,it appears that it's best to use mobile phones less often.
Use your regular phone if you want to talk for a long time.Use your mobile phone only when you really need
it. Mobile phones can be very useful and convenient,especially in emergencies.In the future,mobile phones
may have a warning label that says they are bad for your health.So for now,it's wise not to use your mobile
phone too often.The word"detected"in Paragraph 3 could be best replaced by______________.

问答题Practice 4 Bluetooth is the newest kid on the technology block, and it holds a lot of promise for the assistive technology industry. Named for a 10th Century King of Denmark who unified the kingdoms of Denmark and Norway, Bluetooth is a shot-range wireless communication specification that promises to improve and increase electronic access to a number of environments by overcoming some of the obstacles typical of current technology. Bluetooth technology will enable devices to communicate and transfer data wirelessly and without the line-of-site issues of infra red technology. So how does it work? Bluetooth devices search each other out within their given operational range. Unlike devices that are wired together, Bluetooth devices do not have to be aware of the capabilities or properties of the devices to which they will connect beforehand. Bluetooth devices have a built-in mechanism that lets each device identify itself as well as its capabilities as it connects into this new Bluetooth network. This dynamic network does have a controlling device that designates itself as the master for the connection. Its programming and the capabilities necessary for the given task determine whether or not a device can be a master. For example, a cell phone may act as a master device when connecting to a headset, an ATM, or an information kiosk. However, the same cell phone or headset may act as a slave device to the information kiosk, now acting as the master device, broadcasting emergency evacuation information. The cell phone and kiosk can function in either capacity depending on the required function and their programming.正确答案： 【参考译文】
“蓝牙”作为技术家族的新生儿,为辅助性技术作业带来了不少希望。“蓝牙”得名于10世纪一位统一丹麦和挪威王国的丹麦国王,是一种短程无线通信技术的规范。它能逾越当前技术中的某些典型障碍,有望改善并增强各种环境中的电子通信能力。蓝牙技术能使设备进行无线通信并传输数据,并且不受制于红外技术的两点对线限制。
那么蓝牙是如何工作的呢?
蓝牙设备是在特定的操作范围内相互寻找的。和接线设备不同,蓝牙设备无须事先知道待联设备的能力或性质。蓝牙设备的内置机制可以使每种设备在接入新的蓝牙网络时亮明自己的身份和能力。这种动态网络倒是有一种控制设备,可以把自己指派为联网中的主设备。它的编程和适合特定任务需要方面的能力是其能否成为主设备的决定因素。例如,一部手机如果连上耳机、自动取款机或问讯台,就可以作为主设备。但问讯台如果作为广播紧急疏散信息的主设备,那部手机或耳机就得作为从设备了。手机和问讯台可以按照所需的功能和编程能力作主设备或从设备。解析： 暂无解析 -

问答题Practice 6 Fiber-optic lines will form most of the backbone of the information highway, just as they do for the phone system today. Fiber-optic cable is made of long, thin strands of glass rather than wire, and it transmits information in the form of digitized pulses of laser light rather than the radio waves used by coaxial cable. Because light pulses have shorter wavelengths than radio waves, engineers can cram much more data into fiber-optic lines than into other kinds of cables and wires. A single fiber, for example, can handle a mind-boggling 5,000 video signals or more than 500,000 voice conversations simultaneously. This huge capacity allows it to transmit all signals digitally. So noise or static easily can be filtered out. Finally, because glass is an inherently more efficient medium for transmitting information than other materials, a fiber-optic line can transmit a signal thousands of miles without much “signal loss”. Fiber-optic cable, simply put, is the method of choice for transmitting massive quantities of information over long distances. Another key is “digital compression”—a variety of methods for reducing the amount of digital code (streams of ones and zeros) needed to represent a piece of information—whether it is a document, a still picture, a movie or a sound. Digital compression is most critical for transmitting video, because digitized video consumes enormous amounts of space. Just four seconds of a digitized film, for example, would completely fill a 100-megabyte hard drive. A feature film of typical length, if uncompressed, would occupy more than 350 ordinary compact discs. Compression techniques achieve their gins by recording only the changes from one frame to the next, The background image in a movie scene, for example, typically does not change much from one flame to another. In a digital compression scheme, the background would be recorded only once; after that, only the actors’ movements would be captured. One result is more choices—hundreds of channels coming through your cable TV line instead of dozens. Digital compression also makes it easier to piggyback data onto media that were not designed with data in mind: in particular, phone lines.正确答案：
【参考译文】
光纤电缆构成了今日电话系统的主干线,同样,它也将构成未来信息公路的主干线。光纤电缆的制造材料是细长的玻璃丝而不是金属导线,它的信息传输方式是激光数字脉冲而不是同轴电缆使用的无线电波。由于光脉冲的波长比无线电波的波长短,因而工程师可以输入光纤电缆的信息量之大令其他类型的电缆和导线望尘莫及。例如,一根光纤电缆可同时处理五千个电视信号或50多万次电话通话,简直令人惊奇。这种巨大的能力使它可以实现全部信号传输数字化,从而轻而易举地滤掉噪音或静电干扰。最后要指出的是,玻璃作为媒介,它本身的传输效率便高于其他材料,因而一条光纤电缆可将一个信号传输数千英里而几乎没有“信号流失”。简而言之,光纤电缆是远距离传输大量信息的最佳方式。
另一关键技术是“数字压缩”技术——及减少数码(一连串的l和0)数量的各种方法,这种数码用来表示某种信息,如一份文件、一张静止图片、一部电影或一种声音。数字压缩技术对影像传送来说至关重要,因为数字化影像会占据大量的存储空间。例如,仅仅四秒钟的数字化影片,便要占据一百兆的硬盘存储空间。一部普通长度的故事片,如果未经压缩,要占350多张普通光盘。数据压缩技术只记录一个画面与下一个画面之间的变化,从而实现其功能。例如,电影场景的背景图像在一个画面转为另一个画面时通常是不变的,在数字压缩系统中,背景图像只被记录一次,此后便只记录演员的动作。
数据压缩技术使可供选择的有线电视频道从几十个增加到几百个,数字压缩技术还能使数据更容易通过本不是用于传送数据的媒体线传送——特别是电话线。解析： 暂无解析 -

more than a means of communication一having a mobile phone shows that they are cool and connected.
The explosions around the world in mobile phone use make some health professionals worried.Some
doctors are concerned that in the future many people may suffer health problems from the use of mobile
phones.In England,there has been a serious debate about this issue.Mobile phone companies are worried
about the negative publicity of such ideas.They say that there is no proof that mobile phones are bad for your
health.
On the other hand,why do some medical studies show changes in the brain cells of some people who use
mobile phones?Signs of change in the tissues of the brain and head can be detected with modern scanning
（扫描）equipment. In one case , a traveling salesman had to, retire at a young age because of serious memory
loss.He couldn't remember even simple tasks.He would often forget the name of his own son.This man
used to talk on his mobile phone for about six hours a day,every day of his working week,for a couple of
years.His family doctor blamed his mobile phone use,but his employer's doctor didn't agree.
What is it that makes mobile phones potentially harmful?The answer is radiation.High-tech machines
can detect very small amounts of radiation from mobile phones.Mobile phone companies agree that there is
some radiation,but they say the amount is too small to worry about.
As the discussion about their safety continues,it appears that it's best to use mobile phones less often.
Use your regular phone if you want to talk for a long time.Use your mobile phone only when you really need
it. Mobile phones can be very useful and convenient,especially in emergencies.In the future,mobile phones
may have a warning label that says they are bad for your health.So for now,it's wise not to use your mobile
phone too often.On the safety issue of mobile phones,the manufacturing companies______________.

第15题：
Just how much does the Constitution protect your digital data?The Supreme Court will now consider whether police can search the contents of a mobile phone without a warrant if the phone is on or around a person during an arrest.California has asked the justices to refrain from a sweeping ruling particularly one that upsets the old assumption that authorities may search through the possessions of suspects at the time of their arrest.It is hard,the state argues,for judges to assess the implications of new and rapidly changing technologies.The court would be recklessly modest if it followed California’s advice.Enough of the implications are discernable,even obvious,so that the justices can and should provide updated guidelines to police,lawyers and defendants.They should start by discarding California’s lame argument that exploring the contents of a smart phone—a vast storehouse of digital information—is similar to,say,rifling through a suspect’s purse.The court has ruled that police don’t violate the Fourth Amendment when they sift through the wallet or pocketbook of an arrestee without a warrant.But exploring one’s smart phone is more like entering his or her home.A smart phone may contain an arrestee’s reading history,financial history,medical history and comprehensive records of recent correspondence.The development of“cloud computing,”meanwhile,has made that exploration so much the easier.Americans should take steps to protect their digital privacy.But keeping sensitive information on these devices is increasingly a requirement of normal life.Citizens still have a right to expect private documents to remain private and protected by the Constitution’s prohibition on unreasonable searches.As so often is the case,stating that principle doesn’t ease the challenge of line-drawing.In many cases,it would not be overly onerous for authorities to obtain a warrant to search through phone contents.They could still invalidate Fourth Amendment protections when facing severe,urgent circumstances,and they could take reasonable measures to ensure that phone data are not erased or altered while a warrant is pending.The court,though,may want to allow room for police to cite situations where they are entitled to more freedom.But the justices should not swallow California’s argument whole.New,disruptive technology sometimes demands novel applications of the Constitution’s protections.Orin Kerr,a law professor,compares the explosion and accessibility of digital information in the 21st century with the establishment of automobile use as a virtual necessity of life in the 20th:The justices had to specify novel rules for the new personal domain of the passenger car then;they must sort out how the Fourth Amendment applies to digital information now.
The author’s attitude toward California’s argument is one ofA.disapproval.
B.indifference.
C.tolerance.
D.cautiousness.答案：A解析：观点态度根据题干关键词“California’s argument”，可以定位到文章第四段第一句“They should start by discarding California’s lame argument…”。由第四段第一句话中的“discard（抛弃）”和“lame（没有说服力的）”可以看出作者对于California’s argument是不支持的态度，因此选项A disapproval（不赞成）正确。选项B indifference（漠不关心）不正确，因为如果作者对一个话题不关心 -

The author believes that exploring one’s phone contents is comparable toA.getting into one’s residence.
B.handling one’s historical records.
C.scanning one’s correspondences.
D.going through one’s wallet答案：A解析：事实细节根据题干关键词the author believes和“exploring one’s phone contents is comparable to”可回文定位到文章第四段第三句“But exploring one’s smartphone is more like entering his or her home”，选项A getting into one’s residence（进入某人的住宅）语义与之一致，其中，getting into与entering对应. -
