在9·11襲擊之后，這些問題好像更加急迫了。
點睛本句的主干是questions have never seemed more pressing; In the wake of the Sept. 11 attacks為狀語，have never seemed more pressing通過否定比較級來表示最高級概念。
in the wake of的意思是“隨……之后到來”。如：
Outbreaks of diseases occurred in the wake of the flood. 洪水過后疾病叢生。
考點歸納否定式＋比較級可表示最高級概念：
名詞短語否定式＋比較級表示最高級。如：
Nobody else in the class is taller than John. ＝John is the tallest in the class. 班里沒人比約翰更高。
Nobody works harder than Steven does. ＝Steven works hardest. 沒人比史蒂文更努力。
動詞短語否定式＋比較級表示最高級。如：
The food in that restaurant couldn't taste worse. ＝The food in that restaurant tastes the worst. 那家餐館里的食物不能再糟糕了。
I couldn't have spent more time writing this book. ＝I spent a lot of time writing this book. 我沒法花再多的時間來寫這本書了。
