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.
There is an increased risk for children with the popularization of the Internet because they are likely to______.
选项 A、express their ideas freely while online
B、be exposed to unhealthy information
C、make dangerous friends when chatting online
D、confuse what is good with what is bad
答案B
解析 根据第二段第二句“…an increased risk of one’s children(or oneself)being confronted by an image or text that better might have been left unseen．”可知，互联网的普及同时也带来了一些负面的影响，比如增加了孩子们看到不该看的图片或文本的风险，对应选项B中的unhealthy information(不健康的信息)。故选B。
