(2) The world has not been peaceful these years. Since the terror attack in France in 2015, there have been more horrible accidents in other European countries as well, including England, Belgium, Spain and Turkey. People there are worried about the situation but they are not afraid to face the terrorist organization, ISIS. Why did those attackers choose these nations as their target? In other words, why did the terrorists decide to attack these countries instead of other countries, such as America?    According to some experts and studies, there could be two main reasons. First, these European countries are well-developed nations of high democracy. When terrorists attack them, the symbol of democracy seems to get hurt spiritually. Second, the transportation in Europe is very convenient. In fact, the Europe as a whole has become one large union, called EU, since 1999. They share one currency as well as the market, and the boundaries among each country are not very strict. People in that area can travel from one country to another easily. Terrorists might take advantage of this convenience and then hide themselves everywhere to escape from the police.    Though Taiwan is not a popular aim of the terrorists yet, we should still pay more attention to our surrounding and safety, either when staying within our country or traveling to other places.  terrorist恐怖份子; organization 組織; target 目標; expert 專家;  develop 發展; democracy民主; spiritually 精神上; currency 貨幣;  boundary邊界; strict嚴格; take advantage of 利用
