People hoist their glasses 30 they are sitting around ski lodges, sailing, dancing, or enjoying a football game.
答案：(B) while
while 在這裡表示「當……的同時」，後面並列的 sitting around ski lodges、sailing、dancing、enjoying a football game 都是「活動」而非「地點」，用while銜接這些並列的動態活動更合理；where 是關係副詞，需要修飾地方名詞，但sailing、dancing這些是動名詞活動不是地點，用where文法上兜不起來。
本題大考中心未公布逐題答對率，以下不談數據，只談觀念。
空格後面接著一長串 sitting、sailing、dancing、enjoying，其中 ski lodges 是地方，很容易讓人選 where。這一格要先數成分，再看那一串到底是地點還是活動。
四個選項都是 wh- 詞，先數空格後面那個子句缺不缺成分：they are sitting around ski lodges, sailing, dancing, or enjoying a football game——主詞是 they、動詞是 are sitting／sailing／dancing／enjoying，受詞也齊了，成分一個都不缺。既然不缺，what 就先出局：它自己是一個名詞，進到子句裡一定要占一個位置（同判準：93 年第 18 題、91 年第 25 題、90 年第 20 題、87 年第 26 題）。剩下 where、while、why，這時看那一串在講什麼：sitting around ski lodges（在滑雪小屋周圍坐著）、sailing（航行）、dancing（跳舞）、enjoying a football game（看球賽）——四個並列的都是「活動」，不是「地點」；ski lodges 只是其中一個活動的場所，撐不起整串。所以不是 where。也不是 why——這一句沒有在解釋舉杯的原因。剩下 while（當……的同時）：人們是在做這些活動的同時舉杯，時間上重疊，語意完全吻合。（同時性的說法還有 as，86 年第 23 題考的就是 as 的這個用法。）
where：並列的四個是活動不是地點。why：句中沒有因果關係。what：成分已滿，塞不進去。
while ＋ 子句（當……的同時）、hoist one’s glass（舉杯）、sit around（閒坐在……周圍）、a ski lodge（滑雪小屋）、go sailing（去帆船航行）、just the opposite（正好相反）。
America encourages its young people to drink. 21 , our society makes drinking a part of every celebration. Our personal celebrations, 22 weddings, promotions, graduations, and anniversaries, are 23 linked with drinking. 24 children can attend any family affair without seeing the adults enjoying their liquor. Drinking is part of our national celebrations as well. The Fourth of July means beer and New Year's Eve is an entire night dedicated to the proposition that everyone must get 25 .
Secondly, the shows young people watch on television encourage them to drink. On 26 every soap opera, the characters drink casually and often. The rock videos young people watch over and over again feature alcohol, too. 27 on the videos sit in bars, nightclubs, and roadhouses. Drinking, the message goes, is cool.
The strongest encouragement to drink that young people receive, 28 , comes from advertisers. Beer companies often sponsor the sports events young people watch. In addition, advertisements for liquor, on TV and in print, show situations that are 29 to the young. People hoist their glasses 30 they are sitting around ski lodges, sailing, dancing, or enjoying a football game. We may say we don't want our children to drink, but our messages say just the opposite.
