Privatization， or the threat of it， is a motivation as well. Monopolies （垄断者） that until recently have been free to take their customers for granted now fear what Michael Perry， a marketing professor， calls “the revengeful （报复的） consumer.” When the government opened up competition with Bezaq， the phone company， its international branch lost 40% of its market share， even while offering competitive rates . Says Perry， “People wanted revenge for all the years of bad service.” The electric company， whose monopoly may be short-lived， has suddenly mopped requiring users to wait half a day for a repairman. Now， appointments are scheduled to the half-hour. The graceless El Al Airlines， which is already at auction （拍卖）， has retrained its employees to emphasize service and is boasting about the results in an ad campaign with the slogan， “ You can feel the change in the air.” For the first time， praise outnumbers complaints on customer survey sheets.

1. While + V-ing ...結構︰when／while／once／if／unless／though＋現在分詞說明︰當when，while，once，if，unless，though 等<副詞><連接詞>引導<副詞子句>時，若其<主詞>與<主要子句>相同，可保留該<副詞><連接詞>，其餘部分則化簡為<分詞片語>。 例子：
