36．G 考查上下文聯(lián)系．根據(jù)本段內(nèi)容可知，密碼長度不能過短，長度應(yīng)該至少是8個字符．故選G．
37．A 考查上下文聯(lián)系．根據(jù)"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"可知，如果這些賬戶都有相同的密碼，黑客就能更好地破解多個賬戶．故選A．
38．C 考查上下文聯(lián)系．根據(jù)"Information about what you sent from or saved on your computer can be kept for days or weeks．It is very easy for anyone who sees that information to steal a detailed record of your online activities．"可知，黑客會記錄你訪問過的每一個網(wǎng)站．故選C．
39．D 考查上下文聯(lián)系．根據(jù)"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．"可知，不要使用免費的無線網(wǎng)絡(luò)．故選D．
