C. remove the dangers that can be caused by untold stories

　　D. realize the importance of being honest when making friends

　　【解析】

　　试题分析：本文为议论文本文作者论证了人们之间彼此分享自身经历的重要性。1.C推理判断题。文章第一段告诉读者分享经历很重要；第二段介绍资讯封锁的负面影响也是通过证明不分享消息带来的麻烦从反面来说明论点，故答案为C项。

　　2.C事实细节题。根据第四段中“they often show our weaknesses or expose our disadvantages；they require courage and strength to share”可知人们之所以不愿意和别人分享自己的经历是因为他们缺乏勇气，故答案为C考点：考查社会生活类短文阅读。

　　“Cleverness is a gift while kindness is a choice. Gifts are easy – they’re given after all. Choices can be hard.” –– Jeff Bezos.

　　I got the idea to start Amazon 16 years ago. I came across the fact that the Internet usage was growing at 2,300 percent per year. I’d never seen or heard of anything that grew that fast, and the idea of building an online bookstore with millions of titles was very exciting to me. I had just turned 30 years old, and I’d been married for a year. I told my wife MacKenzie that I wanted to quit my job and go to do this crazy thing that probably wouldn’t work since most start-ups don’t, and I wasn’t sure what to expect. MacKenzie told me I should go for it. As a young boy, I’d been a garage inventor. I’d always wanted to be an inventor, and she wanted me to follow my passion.
