简述期刊广告的优缺点。
参考答案：
期刊广告由于期刊本身特征不同而有所区别。有些期刊属于综合性质，阅读者人数众多、兴趣广泛，宜作多种类型广告；有些期刊属于专业性质，仅针对一些专业人员，如电信工业企业推销技术性较强的通信设备，可选择通信专业性较强的刊物；有些商业性期刊国内外均发行，是出口产品广告的有效媒体。利用期刊作广告的优点是：对象明确，针对性强：保存时间长，信息利用充分；制作精细，图文并茂，能较好地再现产品外观形象，其缺点是：定期发行，难以适时；传播范围窄，成本费用高。

| As a saying goes, every bean has its black.It is impossible to make no mistakes all one's life. My grandpa Nybakken, a carpenter, is no 1 . Several decades ago he made a mistake-a(n) perfect mistake, 2 . On a cold Saturday, Mother's father was building some wooden cases for the clothes his 3 was sending to an orphanage (孤儿院) in Africa. On his way home, he 4 into his shirt pocket to find his glasses, but they were gone. He remembered putting them there that morning, so he drove back to the church. His 5 proved fruitless. When he 6 replayed his earlier actions, he realized what happened. The glasses had slipped out of his pocket unnoticed and fallen into one of the cases, which he had nailed shut. His brand new glasses, having 7 him $20 that very morning, were heading for Africa! He had to drive home 8 . Several months later, the director of the orphanage came to give a report on Sunday night at my grandfather's church, 9 Grandpa and his family also attended. "But most of all," he said, "I must thank you for the 10 you sent last year. You see, the bandits (土匪) had just 11 through the orphanage, destroying everything, including my glasses. I was desperate." " 12 I had the money, there was simply no way of 13 those glasses. 14 not being able to see well, I experienced headaches every day. Then your cases arrived. When my staff 15 he covers, they found a pair of glasses lying on top." Then, still gripped (吸引注意) with the 16 of it all, he continued, "When I tried 17 the glasses, it was as though they had been made just for me! I want to thank you for being a part of that!" The people listened, 18 for the miraculous glasses. But the director surely must have 19 their church with another, they thought. There were no glasses on their 20 of items to be sent overseas. But sitting quietly in the back, with tears streaming down his face, an ordinary carpenter realized the Master Carpenter had used him in an extraordinary way. | ||||
