夜游剑桥或许因为纬度高的原因,英国天黑得早,亮得晚。下午四五点就已暮色沉沉,六点天全黑,早上七八点才天亮。我们到达伦敦希斯罗机场已是下午五六点,室外湿冷湿冷的,口中哈出的白气特别明显。坐上大巴前往剑桥,除了靠近伦敦的公路上汽车较多,一路上都没有什么车,连路灯都少,就像在黑暗的隧道里行驶,没有来路也没有尽头, Cambridge may be due to high latitudes because of the night, the UK dark early, bright evening. Dusk at four or five o’clock in the evening, six days all black, seven or eight in the morning before dawn.
