题目

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。     How can we keep safe personal information on our computers or cellphones? View emails with a careful eye     It's best to view all emails with care. Hackers (黑客) can make emails look like real company emails.  It's best to search for the original source of the information, and try to find the direct link from the site instead of using the link provided in the email.     Use two-factor authentication (双重认证)     Two-factor authentication adds a second level of safety to an account.  It's a safety option that requires a password as well as an additional piece of information only the user would know.     Update apps and operating systems      While these updates may appear to only change the way your phone's software looks, they often come with safety improvements. There may be a bug (软件漏洞). Those bugs are discovered by cell providers or smartphone makers, so it's a good idea to upgrade them.     It's no surprise that changing your password has always been a basic form of protection. But what we pick as passwords and how we manage them are important. First, passwords should never include your personal information. So stay away from names and birthdates. Ideally, passwords are a combination of lowercase (小写) and uppercase (大写) letters and random characters. It could be a strong, long password that doesn't have any personal information, making it harder to remember. A. Manage passwords safety B. Here are some steps to make it. C. It can trick readers into clicking on dangerous links. D. Often users are unwilling to update their mobile devices. E. Combine your personal information with random figures. F. Here are some ways to create your online personal passwords. G. Do it if there's an option for your email, banking site or social media site. 答案：【1】B【2】C【3】G【4】D【5】A
