Just how much does the Constitution （宪法）protect your digital data? The Supreme Court will now consider whether police can search the contents of a mobile phone without a warrant （(授权令) if the phone is on or around a person during an arrest.

California has asked the justices to restore the practice that the police may search through the contents of suspects' smartphones at the time of their arrest. It is hard, the state says, for judges to assess the implications of new and rapidly changing technologies .

The justices would be careless if they followed California's advice. They should start by rejecting California's weak argument that exploring the contents of a smart phone is similar to say, going through a suspect's wallet. The court has ruled that police don't offend against the Fourth Amendment（修正案） when they go through the wallet, of an arrestee without a warrant. In fact, exploring one's smartphone is more like entering his or her home. A smartphone may contain an arrestee's reading history, financial history, medical history and comprehensive records of recent correspondence.

Americans should take steps to protect their own digital privacy and should avoid putting important information in smartphones. 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.

In many cases, it would not be very difficult for authorities to obtain a warrant to search through phone contents. They could still trump （打出王牌）the Fourth Amendment protections when facing severe and dangerous circumstances, such as the threat of immediate harm, and they could take reasonable measures to ensure that phone data are not deleted or altered while a warrant is on the way. The justices, though, may want to allow room for police to cite situations where they are entitled to more flexibility.

But the justices should not swallow California's argument whole. New technology sometimes demands fresh 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 digital necessity of life in the 20th. At that time, the justices had to explain new rules for the new personal domain （领域）of cars. Similarly, the justices must sort out how the Fourth Amendment of the Constitution applies to digital information now.

1.The author's attitude toward California's argument is one of ________

A.disapproval. B.tolerance.

C.indifference. D.cautiousness.

2.The author believes that exploring one's phone content is comparable to

A.scanning one's correspondences. B.handing one's historical records.

C.getting into one's residence. D.going through one's wallet.

3.In paragraph 4 and 5, the author shows his concern that

A.citizens' privacy is not effectively protected.

B.principles are hard to be clearly expressed.

C.phones are used to store sensitive information.

D.the court is giving police less room for action.

4.Orin Kerr's comparison is quoted to indicate that

A.the Constitution should be implemented flexibly.

B.Principles of the Constitution should never be changed.

C.California's argument violates principles of the Constitution.

D.New technology requires reinterpretation of the Constitution

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(执行令)if the phone is on or around a person during an arrest.

California has asked the justices to restore the practice that the police 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 careless if it followed California's advice. Enough of the implications are recognizable, even obvious, so that the justice can and should provide updated guidelines to police, lawyers and defendants.

They should start by casting away California's lame argument that exploring the contents of a smartphone-- a vast storehouse of digital information is similar to say, going through a suspect's purse .The court has ruled that police don't violate the Fourth Amendment when they go through the wallet or pocketbook, of an arrestee without a warrant. But exploring one's smartphone is more like entering his or her home. A smartphone 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 very difficult for authorities to obtain a warrant to search through phone contents. They could still ignore 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, destructive 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 cars; similarly, they must sort out how the Fourth Amendment applies to digital information now.

1.The Supreme Court, will work out whether, during an arrest, it is legal to ____.

A.search for suspects' mobile phones without a warrant

B.check suspects' phone contents without being authorized

C.prevent suspects from deleting their phone contents

D.prohibit suspects from using their mobile phones

2.The author's attitude toward California's argument is one of ____.

A.tolerance. B.indifference C.disapproval D.cautiousness

3.In Paragraph 5 and 6, the author shows his concern that ____.

A.principles are hard to be clearly expressed

B.the court is giving police less room for action

C.phones are used to store sensitive information

D.citizens' privacy is not effective protected

4.Orin Kerr's comparison is quoted to indicate that ____.

A.the Constitution should be carried out flexibly

B.New technology requires reinterpretation of the Constitution

C.California's argument violates principles of the Constitution

Does the Body Burn Fat When You Are Hungry?

Your body stores fat as a way to help protect you against starvation if you can’t take in enough food. However, your fat reserve isn’t the first place your body goes for food. Instead, it reaches out for sugar for energy. 1.

Hunger is normally a reflection that your body has used up energy from recent food you ate and has moved onto getting energy from sugar in your blood. 2. The more sugar you take in, the more fuel your body has to use before it reaches out to the fat stores. If your body doesn’t have enough sugar to supply the energy it needs, it begins to burn fat when you’re hungry instead.

Missing meals and going hungry can change your metabolism (新陈代谢) so it stores fat instead of burning it. 3. However, if you skip meals for several days and severely lower your calorie (卡路里) intake, your body begins to store as much fat as possible.

4. Your body burns up sugar stored in your system and begins to burn fat as you continue to exercise. However, exercising when you’re hungry won’t help you burn fat faster. A recent study shows that the body burns the same amount of fat regardless of whether you are hungry when you exercise.

Staying hungry all day won’t necessarily help you burn fat, but cutting calories is key to losing weight. 5. Snack (吃点心) in between meals to keep your metabolism working all day, which helps it burn more fat than if it’s allowed to slow down when it’s not meal time. Snacking in between meals can help you control your meal sizes at meal time.

A. Exercise is key to burning fat.

B. You shouldn’t cut out food to cut calories.

C. This doesn’t happen in a day of missing meals.

D. Just being hungry doesn’t mean your body is burning fat.

E. If you take in less food than your body burns, you’ll lose weight.

F. Your body stores sugar in case you need it when you feel hungry.

G. Eat five or six small meals throughout the day instead of three large ones.

Fortunately，there are ways to safeguard your privacy on land and in the air．These tips can help you deal with these troubles．

2. "It's not clever to declare on Facebook that you're traveling to somewhere，reminding a wide range of people that your property is sitting empty，"says Danny McLoughlin．"That puts your security at risk．"Wait until you return to start posting vacation photos．

Some homeowners renting their residences may install security cameras．Travelers should find out if the hosts are required to disclose the presence of surveillance devices．If the rental comes with cameras，ensure they aren't in a sensitive area by conducting a careful sweep 3.

Although you can't control how a hotel or airline handles-or mishandles-your data，you can take reasonable steps to ensure the information it has won't get you into trouble．4.

But some of the worst data leaks happen when you're staying at a hotel．For example，a hotel clerk sometimes asks for your name and then announces your room number after you've checked in．You're better off handing the employee your ID when he or she asks for your name and asking the employee to write your room number on a piece of paper．Why？5. Just to be sure，never leave the customer copy behind．You can destroy it later，but keep it under your contro1．

A．It's never been better．

Just how far does the euro(欧元) have to fall before Europe actually becomes reasonable?

Anyone traveling to the old continent from the U.S. in recent years has learned the hard way how expensive it is. The situation has improved in the last couple of months, thanks to the Greek financial crisis. But it still has a way to go.

Alarm about Greece—and other financially unstable countries in Europe—has dragged down the euro sharply. In November, before the crisis struck, you needed about $1.49 to buy one euro. Today you need only about $1.36. That's a 9% cut.

What does that mean for you, the would-be traveler? It's a big sale.

As recently as November, when the euro was flying high, the OECD estimated that countries like France, Italy and Germany were about a third more expensive than the U.S. Not all European countries were quite as expensive for the American visitor: Greece only cost about 17% more than the US, while the Czech Republic (which is not part of the eurozone) was actually about 15% cheaper than back home.

Fast-forward two months, and the situation looks somewhat better.

At current exchange rates, places like France will still cost you about 23% more than the U.S., but cheaper countries such as Spain and Greece are now only about 6% more expensive. The Czech Republic's a fifth cheaper than the U.S.

European prices will only break even(持平) with the U.S. if the euro falls to about $1.10, says the OECD. But is it going to get there?

Greece's financial crisis may or may not be over. Members of a labor union just occupied part of the finance ministry to protest against the planned austerity(紧缩) measures. No, it doesn't inspire confidence!

Julian Jessop, chief international economist at the Capital Economics consultancy in London, sees the euro falling to $1.25 by year-end. “We still think the euro should be a lot lower,” he says. “We think the outlook for the European economy is a lot worse than for the U.S. And Greece is only a symptom of a wider problem: Does the eurozone make sense as a currency union?” If he's right, you may want to wait to change your money or book a trip.

67.   In the passage the writer offers some suggestions to the travellers from______.

A．USA           B．Europe             C．Greece             D．China

68.   The underlined word “it” in the passage refers to ______.

A.the planned austerity measures

B.Greece’s financial crisis

C.the protest from a labor union

D.the decline of the euro in value

69.   Julian Jessop has a negative attitude toward the euro because he thinks ______.

A.Greece’s financial crisis may not be over

B.the euro will drop to $ 1.25 by the end of the year

C.the European economy is a lot worse than the US’

D.the other European countries have a similar problem like Greece

70.   The purpose of the author writing the passage is to tell the readers that ______.

A.the euro shall be further reasonably lowered

B.travelers to Europe will save less in the future

C.the economic situation in Europe is worsening

D.the Greek financial crisis influences the whole Europe
