　　(2015云南第一次高中毕业生复习统一检测,B)

　　If the hackings(黑客行为)taught us anything in 2017,it’s actually nothing.

　　Password management firm SplashData released its list of the worst passwords of the year and it’s just as terrible as you’d think.The most common leaked password in 2017 was “123456” followed by “password”—both topped the list the year before,too.

　　While numbers were as popular as ever as passwords,sports terms like “baseball” and “football” were used more often.Birthday years were common too(especially 1989,1990,1991 and 1992)and names like “Michael”,“Jennifer” and “Hunter” are also among the top 100 worst passwords of 2017.
