Researchers have developed new software ...

Researchers have developed new software using smart phones’GPS and imaging abilities that determine the exact location of distant objects as well as monitor the speed and direction of moving objects.The software could eventually allow smart phone-armed soldiers to target the location of their enemies.On the home front,the software could be used by everyone,including golfers judging distance to the green and biologists documenting the location of a rare animal without disturbing it.

“The great advantage of a Smartphone is that it provides so many tools in a single,readily available,relatively inexpensive package,”said Qia Wang,a doctoral student who led the development of the software.“For example,on the battlefield,a soldier needs a rangefinder,compass,GPS and other tools to get information before calling in an air strike.With our software,the soldier can have all those instruments in one device that can be purchased off the shelf.When that soldier returns from War,she can use the same Software to protect her family by clocking a speeder near her children’s school and catching the criminal on video.”

Wang and his colleagues developed their software to locate and track:

Targets of known size—when the size of the target is known.a single image is enough to pinpoint the target’s location.

Targets of unknown size—If the exact size of a target is unknown,the software uses two images to triangulate the location of the target·

Moving targets—By taking a short video of a moving target,the smartphone software can calculate how fast the target is moving and in what direction it is going.

“Currently,our software is limited by the physical abilities of smartphone hardware,but the devices are improving rapidly,”Wang said.“We expect that improvements in GPS accuracy,battery  life  and  camera  resolution  will  allow  our  software to  make  even  more  accurate observations.”

1.From Paragraph 1 we can know that the new software can.

A.determine the speed of moving objects   

B.1ocate objects in the distance exactly

C.defend soldiers against their enemies

D.help biologists protect rare animal

2.The example given by Qia Wang is meant to .

Many years ago,a French naturalist,the Count de Buffon,wrote some books about natural history.The books were a great success even though some critics did not like them.Some critics said,“Count Buffon is more of a poet than a scientist.”

Thomas Jefferson did not like what the Count had said about the natural wonders of the New World.It seemed to Jefferson that the Count had spoken of natural wonders in America as if they were unimportant.

This troubled Thomas Jefferson.He too was a naturalist,as well as a farmer,inventor,historian,writer and politician.He had seen the natural wonders of Europe.To him,they were no more important than those of the New World.

In 1788,Thomas Jefferson wrote about his home state,Virginia.While writing,he thought of its natural beauty and then of the words of the Count de Buffon.At that moment.Jefferson created a new word—belittle.He said.“The Count de Buffon believes that nature belittles her productions on this side of the Atlantic.”

Noah Webster,the American word expert,liked this word.He put it in this English language dictionary in 1806,“Belittle—to make small,unimportant.”

Americans had already accepted Jefferson’s word and started to use it.In 1797,the Independent Chronicle newspaper used the word to describe a politician the paper supported.“He is an honorable man,”the paper wrote,“so let the opposition try to belittle him as much as they please.”

In 1872,a famous American word expert decided that the time had come to kill this word.He said,“Belittle has no chance of becoming English.And as more critical writers of America,like those of Britain,feel no need of it,the sooner it is forgotten,the better.”

This expert failed to kill the word.Today.belittle is used where the English language is spoken.

As the new semester begins,millions of college students across the country are trying hard to remember how best to write a paper-or,more likely,how best to delay that paper.

Procrastination is the thief of time and a lot of students suffer from it.They can spend whole days in the library doing nothing but staring into space,eating snacks,surfing the Internet,watching videos and looking at their pretty peers sitting around them,who,most likely,are doing nothing either.

Paralyzed by their habit to procrastinate,they write micro blogs about their fears,asking their online friends if they sometimes have the same issue.But this does nothing to solve their problems.

According to a recent report by the BBC,95 percent of us procrastinate at some point and 20 percent of the world’s population are procrastinators,complicating their lives with their continual delaying of tasks.

Procrastinators like to find excuses to justify their behavior,but BBC columnist Rowan Pelling says they are all wrong.Many procrastinators tell themselves they are perfectionists who work best under pressure.Pelling says this is nonsense,as work done at the last minute is more likely to have mistakes than work done on time.

She says the behavior of procrastinators often makes them feel flustered and ashamed,inconveniences others,and annoys loved ones.

Fortunately,social seientists have made tireless efforts to understand this behavioral shortcoming and offer strategies to control it.Piers Steel,a Canadian social scientist and author of The Procrastination Equation,believes humankind is“designed”to procrastinate.Nevertheless,he suggests a couple of good ways to get through the task at hand.

The first one is obvious:Break the task down into small pieces and work your way through them methodically.

The second is clever:Give a trusted friend a sum of money and tell them that if you don’t complete the task you have undertaken by a specific time,they can keep it or donate it to a cause you hate.

1.What does the underlined word“Procrastination” in the second paragraph refer to?

A.A bad habit of putting work or tasks off.

B.A thief who steals time and money in college.

C.A college student who learns nothing.

D.A study way of doing nothing in the library.

2.Which of the following statements is true according to the text?

A.College students can have their papers written if they delay them.

B.Many students don’t know what to do in the library.

C.Students can’t solve their procrastination by writing micro blogs.

D.20%of the procrastinators make their life complicated.

3.According to Rowan Pelling,we can learn that procrastinators .

A.can find reasonable excuses for their behavior

B.are able to work best under pressure

C.are more likely to avoid mistakes at work[]

D.may upset themselves and their loved ones more frequently

4.Which of the following may Piers Steel support?

A.Human beings are not born to be procrastinators.   

B.Complete your tasks or work step by step.

C.Give your trusted friend money and ask him to help you finish your tasks.

D.You can’t control procrastination but you can avoid it.

5.What’she best title of the text?

A.Who steals my time?   

B.The solutions to procrastination

C.I’ll do it tomorrow,I swear!

D.Don’t do nothing!

In Singapore,most of us love window-shopping while some others enjoy having a picnic at East Coast Park or Changi Beach on sunny days.Singaporeans are never bothered by the occasional thunderstorm.However,we know that if it rains for long continuous periods,there will be more serious effects.Just recently the main shopping street of Orchard Road was flooded and some part of Bukit Timah was impassable(不能通行的)to traffic.People reacted by writing in to the newspaper to complain about this! We forget that other countries suffer much worse effects.

Elsewhere,heavy tropical(热带的)storms often result in floods that ruin crops especially in Thailand and Malaysia.This in turn usually means that the price of rice and vegetables here in Singapore will rise because we import these products from them.If there is a typhoon or tsunami,thousands of lives are lost too.This happened in Indonesia and Phuket in Thailand in 2004 and It serves to remind us of how Mother Nature can cause great damage.

Weather patterns in general have changed dramatically in recent years.Scientists believe that global warming and the resulting melting of the polar ice-cap has caused the level of the ocean to rise.This in turn causes flooding of low-lying areas in countries where the land is rather flat and some parts of which is below water level.It is believed that human activities have caused Mother Nature to show her extreme anger,so it is now important that we really work together to cut down on harmful activities,for example,illegal logging(伐木)or irresponsible forest-burning to clear land for farming.
