【简答题】
Translate the following paragraphs into Chinese. The next few years could be messy. We will see more data breaches, and we will almost certainly see a vigorous debate about how much control over the digital realm we should cede to governments in return for security. The truth is that securing cyberspace will require solutions from many realms: technical, legal, economic and political. It is also up to us, the general public. As consumers, we should demand that companies make their products more secure. As citizens, we should hold our governments accountable when they intentionally weaken security. And as individual points of potential failure, we have a responsibility to secure our own stuff. Defending ourselves involves simple steps such as keeping our software up-todate, using secure Web browsers, and enabling two-factor authentication on our e-mail and social-media accounts. But it also involves being aware that each of our devices is a node in a much larger system and that the little choices we make can have wideranging effects. Again, cybersecurity is just like public health. Wash your hands and get vaccinated, and you can avoid spreading the disease further.
