“Get your hands off me, I have been stolen,” the laptop, a portable computer, shouted. That is a new solution to laptop computer theft: a program that lets owners give their property a voice when it has been taken.

The program allows users to display alerts (警报)on the missing computer’s screen and even to set a spoken message. Tracking software for stolen laptops has been on the market for some time, but this is thought to be the first that allows owners to give the thief a piece of their mind.

Owners must report their laptop missing by logging on to a website, which sends a message to the model: a red and yellow “lost or stolen” banner pops up on its screen when it is started. Under the latest version(版本) of the software, users can also send a spoken message.

The message can be set to reappear every 30 seconds, no matter how many times the thief closes it. “One customer sent a message saying, ‘You are being tracked. I am right at your door’,” said Carrie Hafeman, chief executive of the company which produces the program, Retriever.

In the latest version, people can add a spoken message. The default (系统设定)through the computer’s speakers is: “Help, this laptop is reported lost or stolen. If you are not my owner, please report me now.”

The Retriever software package, which costs $29.95 (£21) but has a free trial period, has the functions of many security software programs. Owners can remotely switch to an alternative password immediately if they fear that the thief has also got hold of the access details.

If a thief accesses the internet with the stolen laptop, Retriever will collect information on the internet service provider in use, so that the police can be alerted to its location.

Thousands of laptops are stolen every year from homes and offices, but with the use of laptops increasing, the number stolen while their owners are out and about has been rising sharply.

Other security software allows users to erase data remotely or lock down the computer.

1.The expression “to give the thief a piece of their mind” can be understood as “_______”.

A. to give the thief an alert mind

B. to express the owners’ anger to the thief

C. to remind the thief of his conscience(良心)

D. to make the thief give up his mind

2.Different from other security software, Retriever can ______.

A. record the stealing process

B. help recognize the lost laptop

C. lock down the computer remotely

D. send a spoken message

3.One function of the program is that it allows the owner to ______ at a distance.

A. change some access details for switching on the laptop

B. turn on the laptop by using the original password

C. operate the laptop by means of an alternative password

D. erase the information kept in the stolen laptop

4.Which of the following can best summarize the main idea of the passage?

A. With no Retriever, thousands of laptops are stolen every year.

B. A new software provides a means to reduce laptop theft.

C. Retriever has helped to find thieves and lost computers.

D. A new program offers a communication platform with the thief.

Last month, students from one hundred and three universities in eighty-eight countries took part in an international computer programming contest. The Battle of the Brains took place in Harbin, China. 1.

Jerry Cain, coach of Stanford University Team, California, says “One of the programming problems was trying to figure out how to break a chocolate bar into a certain number of pieces of a certain number of sizes and to do it as quickly as possible. 2.

The students first listed the problems in order of difficulty. 3. They designed ways to test their solutions. And they wrote needed software systems. Even the winning team from Shanhai Jiaotong University in China was not able to solve all the problems within the given time limit. Stanford’s team solved five problems and finished in 14th place. Stanford was one of twenty-one American universities that took part in the contest this year.

4. . It began in 1970 at Texas A and M University. The contest quickly became popular in the United States and Canada. It developed and grew as more and more schools took part in local and area contests.

The first final competition was held in 1977 at the Association for Computer Machinery Computer Science Conference. Today, a network of universities holds area competitions that send the winners to the world finals, now organized by IBM. Contest spokesman Doug Heintzman says the world champions receive prizes and scholarships. 5.

A. The competitors show great interest in IBM.

B. Then they figured out the requirements of each.

C. And that’s probably the simplest of all of them.

D. This competition is an opportunity to be recognized by famous universities from the world.

E. Three-person teams from each school had five hours to solve eleven real world problems.

F. The official name of the Battle of the Brains is the ACM International Collegiate Programming Contest.

G. They are also guaranteed an offer of employment with IBM.

Many people think that they have to accept whatever life throws at them. They'll say, "This is my fate. I cannot change it.” 1. . You don’t have to suffer needlessly. Your fate depends on you, not on any other outside factors

We want to be happy and live our life to the fullest, but we have to do our share of making the effort to live the life of our dreams.

Alaska’s Arctic lakes now freeze later and melt earlier in the year than in 1950,leaving them easy to suffer water loss from evaporation(蒸发)and possibly adding to local warming,a new study finds.The winter ice season near Barrow,Alaska,is shorter than in 1950,researchers reported Jan.30 in the journal The Cryosphere.

Lake ice is also thinner each winter.The scientists surveyed 402 lakes on the North Slope,where permafrost (permanently frozen ground)and shallow lakes dominate the areA. In 2011,the lake ice was 38 percent thinner than in 1950,and 22 percent fewer lakes froze through to their bottoms.

“When we saw the actual numbers we were shocked at how dramatic the change has been,”lead study author Cristina Surdu,of the University of Waterloo in Canada,said in a statement.Surdu and her co-authors analyzed the changes in lake—ice thickness and ice cover with satellite images and climate model simulations(satellite images are only available from 1991).

The climate models suggest the Arctic lakes froze almost six days later and broke up about 18 days earlier in the winter of 2011 compared with the winter of 1950.“The changes in ice and the shortened winter affect Northern communities that depend on ice roads to transport goods,”Surdu saiD. For example,every winter,oil companies build roads over frozen lakes to carry supplies to Prudhoe Bay.

“The dramatic changes in lake ice may also contribute to further warming of the entire region,because open water on lakes contributes to warmer air temperatures,”Surdu saiD. The Arctic is warming twice as fast as the rest of the planet,for reasons that may include its layered atmosphere,which traps heat,and the loss of sea ice and snow cover,which help reflect the sun’s energy when present.

3.How many days was the winter ice season of Arctic 1akes in 2011 shorter than that in 1950?

A. 6 days.

B. 12 days.

C. 18 days.

D. 24 days.

4.What is the last paragraph mainly about according to Surdu?

A. What reflects the sun’s energy.

B. How its layered atmosphere traps heat.

C. Why our planet is warming.

D. Why the Arctic region is becoming warmer.
