“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.

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

●Does failure really exist?

If you believe you have failed, then you have. If you believe you don’t have the ability to succeed, then you don’t. 1. The moment you decide to give up or stop working toward your goals, failure is born.

● 2.

Most people give themselves an out without even realizing it. They are willing to work hard on reaching their goals, but only until the going gets too rough or their energy dies down. Don’t do that! 3. Never quit, never admit failure, and never lose heart.

●Don’t believe in a clear finish line for goals.

It’s a good idea to set a general timeline, but remember that something will be beyond your control. 4. If you lock yourself into a given timeline, you might make yourself feel like a failure! Instead, get a general idea of when you’d like your goal to be completed. Then take it one day at a time and focus on making progress instead of reaching the finish line in as little time as possible.

●Be sure that you don’t see difficulties as failures.

Difficulties mean only one thing: it’s not time for your goal to be completed yet. That’s it! It doesn’t mean you failed; it doesn’t mean you’re weak; it doesn’t mean you’ll never achieve your goals. 5. You’ve got to keep moving forward and find a way over, around, or through the difficulties.

A. Never give up on yourself.

B. Failure only exists in your own mind!

C. That’s exactly how failure makes us feel.

D. It simply means you have not done enough yet.

E. You can never say exactly when your goal will be reached.

F. Instead, make up your mind to make your goal happen, no matter what!

G. Work hard towards your goal, and you will be likely to get good results.
