Most of us lead a busy life.  小题1: We think, “If I reached my goal, then I would be happy”, or “If I could get a better job, then I would enjoy life.” But why not enjoy life right now?

Firstly, take time to notice and appreciate the beauty in your own surroundings.  小题2: “There is a great big world of wonder and beauty around us!” And as Brodersen explains. “Look for the beauty of the sunrise and of a friend’s smile that brightens your day. Open your eyes to see the beauty you might not normally see. Doing so helps to cheer you up.”

Secondly, taking time to experience some simple pleasures also can bring joy to your heart and ease your stress. Take me for example.  小题3: One universal simple pleasure is finding things that make you laugh. Make time to laugh every day.

Thirdly, don’t take your family and friends for granted. Rich, rewarding relationships add greatly to the enjoyment of life. When you think of someone, why not call, e-mail or write them?  小题4: As Wayne Lawton explains, “Invest time in relationships. Remove the attitude, what’s in it for me?

2005年x月x日下午，XX大学学生王文、李波、张彬在自习室相遇。王文：哎，你们注意没有，这两天，胡 * * * * 去北美访问，随行的居然有70多家象海尔集团这样的企业“大腕”。上次加拿大 * * 访华，来了277家企业，360多人。领导人出访带这么多企业代表干什么李波：这有什么新鲜!当年克林顿一上台不就宣布在世界上推销美国产品是他的责任吗韩国更绝，居然要求所有的外交官都要成为韩国商品的推销员。张彬：所以啊，EADS的老总跟德国 * * 施罗德访华，拿了价值13亿美元的合同，包括23架空中客车，还有为北京奥运会提供的安保系统。李波：施罗德有什么办法国内经济不景气，他可以用这些订单来证明自己还是有海外营销能力的嘛。现在领导人出访可不能只谈友谊，经济合作程度是考察领导人出访成果的一个主要指标。王文：难怪欧盟不顾美国反对，要取消对华武器禁运，看来也是出于经济利益考虑。张彬：经济全球化时代竞争这么激烈，要保护本国利益，又不能损害别国利益，难啊。看来各国外交都得为经济“打工”。李波：有位外交官不是说，50年前．如果大使讲经济会被认为是笑柄，现在大使如果不懂经济更会成为笑柄。冷战期间，国与国的较量，军事力量起着重要的作用。现在靠什么还不是靠经济与技术!王文：看来，世界真的变了!注l：EADS指欧洲航空防务与航天公司根据以上材料回答问题 (1)他们正在讨论国际社会发生的一种什么样的变化 (2)为什么“现在大使如果不懂经济更会成为笑柄”
