　　D

　　(2016·东北三校二模)The stories we share with one another are important. They show wisdom and provide inspiration. They are important to our development. But sometimes people choose not to tell.

　　Consider the negative effects of not sharing a story in the news: People are wondering if public health officials are holding back too much information about the recent outbreak of Ebola.

　　There is a danger in holding back stories that ought to be told. Bobette Buster said it like this, “The fact is, history has shown us that stories not told can become like a dangerous genie (妖怪) left in a bottle. When

　　they are finally uncorked,_their power to destroy is set free.”

　　There are a number of reasons why we hide parts of our story: They often show our weaknesses or expose our disadvantages; they require courage and strength to share; and of course, there are some stories that should be kept secret — especially those that embarrass someone else.

　　Most of us have two selves: The one we display on the outside and the one we actually are on the inside. And the better we get at hiding the stories that show our true selves, the more damage we may be causing to ourselves and to others.
