How to Protect Yourself from Hackers Online
An increase in cyberattacks (网络攻击) makes the Internet seem like a scary place these days. How can individuals protect or make it more difficult for hackers to access their information? Here are several tips that can help you protect against cyberattacks：
__1__
Hard passwords include upper and lower case letters, numbers and special characters. They should be at least eight characters in length. They should also not spell out words easy for hackers to find, like your pet's name or the name of a family member.
Change your password regularly
A very common mistake made by users is to create one hard password, but then never change it. Remembering a long list of complicated passwords can be difficult. But no password is unbreakable. Hackers are better able to hack multiple accounts if those accounts all have the same password. A password management service, like Dashlane or PasswordBox, can help you keep track of hard passwords.__2__
Clear your browser (浏览器) history
This goes for all the devices you use in a day—your home computer, your work computer, or your friend's iPad. Internet browsers like Firefox or Chrome keep track of where you've been and what you've done online. They keep records of every site you visited. __3__ It is very easy for anyone who sees that information to steal a detailed record of your online activities.
Do not use free WiFi
__4__ Often, a user does not need a password to connect to these wireless networks. These services might be useful, but they're also an easy way for hackers to access everything on your device.
Use antivirus protection
There are many antivirus services available for users. __5__ Some antivirus services are even free. They are a great way to have a professional help keeping users one step ahead of hackers.
A．Be careful while using thumb drive
B．These services permit users to easily store and secure their passwords.
C．Make your password harder to hack
D．They can offer many different types of computer protection.
E．An increasing number of public places now offer free wireless access to the Internet.
F．Information about what you sent from or saved on your computer can be kept for days or weeks.
G．Unless you really need it, it is best not to use it.
答案与解析
介绍性说明文。如何保护电脑免受黑客攻击？本文作者提出几个有效的建议：设置高难度密码；常常更换密码；清除浏览器记录；勿使用免费wifi；使用杀毒软件。
1．C 主旨大意题。根据下文阐述的内容：高难度密码最少有八个字符长度。包括大小写字母，数字和生僻汉字等。这样做的目的是使密码难以被黑客破译。故C项切题。
2．B 上下文衔接题。根据中心句“Change your password regularly”以及上文“A password management service, like Dashlane or PasswordBox, can help you keep track of hard passwords.”可知，密码要经常换。密码管理服务软件，像Dashlane 和 PasswordBox会帮助用户很容易储存和保护密码，使得黑客难以攻破。故B项切题。
3．F 上下文衔接题。因为在电脑中你发送和储存的信息会保持几天或几个星期，所以“It is very easy for anyone who sees that information to steal a detailed record of your online activities.(很容易让人窃取你在线活动的详细记录)”。故F项切题。
4．E 上下文衔接题。很多公众场合都提供免费的网络路径。所以“Often, a user does not need a password to connect to these wireless networks.(用户不用密码就可以进入网络)” 。故E项切题。
5．D 上下文衔接题。“There are many antivirus services available for users.(电脑用户有很多杀毒设施)”，所以它们给电脑提供多种多样的保护。故D项切题。
