The other day, my friend Jane was invited to a 40th birthday party. The time printed on the invitation was 7:30 pm．Jane went off with her husband, expecting a merry evening of wine, food, and song．
By 9:45, everybody was having great fun, but no food had appeared. Jane and David were restless. Other guests began whispering that they, too, were starving．But no one wanted to leave, just in case some food was about to appear. By 11:00, there was still no food, and everyone was completely off their heads. Jane and David left hungry and angry．
Their experience suggests that the words on the printed invitations need to be made clearer. Everyone reads and understands the invitations differently. Most of us would agree that 6:30 - 8:30 pm means drinks only, go out to dinner afterwards; 8:00 pm or 8:30 pm means possible dinner, but 9:30 pm and any time thereafter means no food, eat beforehand, arrive late．
But this is not always the case．If asked to a students’ party at 6:30 pm, it is unaccepted for guests to appear on time. Being the first to arrive — looking eager — is social death. When my mother is asked to a party at 6:30, she likes to be there, if not on time, then no later than seven．My age group (late thirties) falls somewhere between the two, but because we still think we’re young, we’re probably closer to student-time than grown-up time．
The accepted custom at present is confusing, sometimes annoying, and it often means you may go home hungry, but it does lend every party that precious element of surprise．

(答案→)B 解析：这篇文章讲述的是参加晚会的社会习惯，说明我们要遵守社会习俗。【小题1】猜词题：参加晚会的人没吃晚饭，到晚11点，人们饿疯了。选B【小题2】推理题开头的故事做为例子，说明邀请信函令人迷茫，人们无法把握该如何去做。选B 【小题3】推理题：第四段前几句说明，年轻的学生赴晚会迟到很正常。急切地第一个赶到的人太少见了。选D【小题4】主旨题：从全文可知，不同年龄段的人到达晚会的时间不同，对晚会时间理解不同，不遵从社会习惯，便会出现饿肚子等现象。所以，按社会习俗参加晚会极为重要。选C
