听力原文: Computer users are advised to adopt good computing practices to keep their computer virus-free. "Protecting our computers against virus attacks is very important nowadays when computers are commonly and widely used in our home and offices." said a spokesman for the Information Technology Services Department (ITSD).
"Typical payload of computer virus can range from cresting annoyances such as affecting the mouse, keyboard or other computer functions, to more destuctive actions like modifying or deleting files, or exposing secret information from the hard disk of the victim's computer." Some computer virus may format the hard disk to corrupt all data stored inside the computer.
"Besides, there are also computer viruses that will create mass mailing or scanning traffic not only to turn infected computers into a platform. for launching further attacks to other computers, but also to consume mailbox storage and network bandwidth."
"As a result, the network and computer systems will be overloaded and the normal operation of the network and computer systems will be seriously affected." said the spokesman.
He noted that the impact was particularly singnificant due to the current highly interconnected computer notwork environment." To avoid such inconveniences and losses, we should take effective computing practices to prevent our computers from virus infections .In fact, such practices are simple and easy." said the spokesman.

A.Computers are commonly and widely used in home and offices nowadays.
B.Computers are easily to be attacked.
C.Adopting good computing practices is a good advice to protect the computer.
D.The viruses are too fearful, computer is not safe any more.

People will be alert and receptive if they are faced with information that gets them to think about things they are interested in. And someone with a history of doing more rather than less will go into old age more cognitively sound than someone who has not had an active mind.
Many experts are so convinced of the benefits of challenging the brain that they are putting the theory to work in their own lives." The idea is not necessarily to learn to memorize enormous amounts of information," says James Fazard, associate director of the National Institute on Aging." Most of us don't need that kind of skill. Such specific training B of less interest than being able to maintain mental alertness." Fozard and others say they challenge their brains with different mental skills, both because they enjoy them and because they are sure that their range of activities will help the way their brains work.
Gene Cohen, acting director of the same institute, suggests that people in their old age should engage in mental and physical activities individually as well as in groups. Cohen says that we are frequently advised to keep physically active as we age, but older people need to keep mentally active as well. Those who do are more likely to maintain their intellectual abilities and to be generally happier and better adjusted." The point is, you need to do both," Cohen says." Intellectual activity actually influences brain-cell health and size."
People who are cognitively healthy are those ______.
A.whose minds are alert and receptive
B.who are highly intelligent
C.who can remember large amounts of information
D.who are good at recognizing different sounds
