而引起人们对那些令人无法忍受的广告的许多抱怨。设空处修饰名词purposes，应用形容词修饰。故填educational，意为“有教育意义的”。
6．unbearable 解析：考查词形转换。句意见上一题解析。根据句中的complaints可知，该空用bearable的反义词，在单词前加前缀un-。
7．though/although/while 解析：考查连词。句意：除此以外，尽管某些尖锐的评论很吸引眼球，但或许会误导年轻人。根据句意，设空处引导让步状语从句，可用though，although或while引导。
8．entertaining 解析：考查非谓语动词。句意：依我看，此类节目应该承担更多的责任而不仅仅是娱乐大众。分析句子结构可知，of为介词，故用动名词作宾语。
9．As 解析：考查定语从句。句意：正如所期待的那样，这些节目应该在形式和功能上都起积极的作用。本句为as引导的非限制性定语从句，as意为“正如”。类似的结构有：众所周知(As is known to all...)，正如报道的那样(As is reported...)等。
10．media 解析：考查名词单复数。句意：同时，媒体也应该保护我们社会的价值观。根据句意可知此处应用复数，表示各种媒体，故“媒体”要用复数media。
Ⅳ.短文改错 Sunny31st，July
It was sunny today and I was in a good mood.Tired of studying or the noise of city life，I come to the ecology park to enjoy scenery and get relaxing in the afternoon.
While I arrived at the park，what came into its sight were the thick green trees.The air was fresh.In addition，I could clearly see a path around the pond.Lying on the grasses decorated with various flowers，I felt with ease because all that I wanted was peace inside.
Therefore，with time going by quickly，the sun was setting in the west.So I had to return back home.I would never forget such romantic experience，which was really beyond description.
