On arriving at the shore, the girl struggled up the cliff towards the light she had seen. (New Concept English, Book 2, L. 33)
[原译 1] 当姑娘到了岸边后, 她奋力爬上悬崖, 朝她看见的灯光爬去。[《新概念英语》(2), 朗文出版公司、世界图书出版公司, 1993, p. 138]
[原译2]到达岸边后，姑娘朝着她看到的灯光方向挣扎着往峭壁上爬去。（《新概念英语》新版第二册，外研社，p.154）从译文看，on arriving = after arriving。是否可以这样理解？
不能这样来理解。on + 动名词(或表动作的名词)这个结构表示它所表达的动作刚一发生或完成,句子谓语所表达的动作便接着发生。它相当于 as soon as 引导的时间状语从句。例如：
-
On reaching the city, he called up Lester. (Dreiser) 他一到达那个城市，就给莱斯特打了电话。
-
I shall write to A. P. Watt on hearing from you. (Yeats) 我一收到你的来信, 将立即给 A. P. 瓦特写信。
-
On arriving in England, they were taken to the Crystal Palace by train. (New Concept English, Book 2, L.80) 他们一到英国便乘火车去水晶宫。
-
On entering a shop, he would ask for a new perfume called 'Scented Shadow' or for 'insoluble bath cubes.' (New Concept English, Book 3, L. 52) 一走进商店，他就立即询问叫做“香影”的新型香水或是“不溶浴皂”。
-
On his return from Europe, Lester set to work in earnest. (Dreiser) 莱斯特刚一从欧洲回来，便开始认真地工作。
-
On his arrival at the airport he was greeted by the Prime Minister. 他一到达机场便受到总理的欢迎。
-
We demand cash on delivery. (RCD) 我们要求货到付款。
而 after + 动名词结构只表示“在……之后”，而不表示另一动作紧接其后发生。例如：
-
After sending you that letter I recollected how stupid I was. (Yeats) 当我把那封信寄给你之后我才想到自己有多傻。
-
She put forward the suggestion to the director, who, after discussing it with other comrades, decided to accept. 她将建议交给了主任，主任与其他同志讨论后决定采纳。
-
