问题    During the past few years, the popularization of the Internet, by lowering the cost of global communication to moderate levels, is leading to a near-perfect market for information. It has bred enterprises that grow and change with astonishing speed, creating millionaires and invigorating(振兴) the economy. The Net has brought to even poor libraries a wealth of resources at very low cost. It has enabled individuals to speak in forums small and large, with an ease and fluency that would delight the founders of this nation, if they could see email, the World Wide Web, Usenet, and online chat.
   The tremendous good done by the popularization of the Internet has caused some problems, of course. Chief among these are a weakening of privacy, greater exposure for matters that most people would prefer were absent from society, such as hate speech and child pornography, and an increased risk of one’ s children (or oneself) being confronted by an image or text that better might have been left unseen. The Internet has brought the entire world into the living room, but some people are finding that there are certain parts of the world they would prefer not to have anywhere in their home. An example that has become an everyday displeasure for many is junk email, also called "spam". On a bad day, up to 30% of the email processed by major Internet service providers is spam, much of it promoting sex sites and get-rich-quick schemes. Many people have had to abandon their email accounts, as they become filled with trash. Left unchecked, spam could spoil the great public good of the Internet.
Junk email is used as an example to demonstrate the Internet may______.
选项 A、help people become millionaires quickly
B、bring great troubles to one’ s life
C、give excitement to people
D、bring about an age of information
答案B
解析 根据第二段第四句中的“displeasure”以及下文所讲的垃圾邮件的泛滥让许多用户不得不放弃邮箱账号可知，B项正确。
