         "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 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 visiting a website, which sends a message to the model:
    a red and yellow "lost or stolen" sign appears 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. For example, the laptop's speaker will say
    "Help, this laptop is reported lost or stolen. If you are not my owner, report me now."
         The Retriever software package, which costs $29. 95 but has a free trial period, has the functions
    of many security software programs. Owners can remotely switch to an alternative password 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 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 this conscience
    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 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.

    The Basics of Math－Made Clear

    　　Basic Math introduces students to the basic concepts of mathematics, as well as the fundamentals of more tricky areas．These 30 fantastic lectures are designed to provide students with an understanding of arithmetic and to prepare them for Algebra(代数)and beyond．

    　　The lessons in Basic Math cover every basic aspect of arithmetic．They also look into exponents(指数), the order of operations, and square roots．In addition to learning how to perform various mathematical operations, students discover why these operations work, how a particular mathematical topic relates to other branches of mathematics, and how these operations can be used practically．

    　　Basic Math starts from the relatively easier concepts and gradually moves on to the more troublesome ones, so as to allow for steady and sure understanding of the material by students．The lectures offer students the chance to “make sense” of mathematical knowledge that may have seemed so frightening．They also help students prepare for college mathematics and overcome their anxiety about this amazing－and completely understandable－field of study．

    　　By the conclusion of the course, students will have improved their understanding of basic math．They will be able to clear away the mystery(神秘性)of mathematics and face their studies with more confidence than they ever imagined．In addition, they will strengthen their ability to accept new and exciting mathematical challenges．

    　　Professor H．Siegel, honored by Kentucky Educational Television as “the best math teacher in America,” is a devoted teacher and has a gift for explaining mathematical concepts in ways that make them seem clear and obvious．From the basic concrete ideas to the more abstract problems, he is master in making math lectures learner-friendlier and less scary．

    　　With a PhD in Mathematics Education from Georgia State University, Dr．Siegel teaches mathematics at Central Arizona College．His courses include various make-up classes and a number of lectures for future primary school teachers．

    　　If the course fails to provide complete satisfaction to you, you can easily exchange it for any other course that we offer．Or you can get your money back．
