L 32 [1]A lost ship
The salvage operation had been a complete failure. The small ship, Elkor, which had been searching the Barents Sea for weeks, was on its way home. A radio message from the mainland had been received by the ship's captain instructing him to give up the search. The captain knew that another attempt would be made later, for the sunken ship he was trying to find had been carrying a precious cargo of gold bullion. Despite the message, the captain of the Elkor decided to try once more. The sea bed was scoured with powerful nets and there was tremendous excitement on board when a chest was raised from the bottom. Though the crew were at first under the impression that the lost ship had been found, the contents of the chest proved them wrong. What they had in fact found was a ship which had been sunk many years before. The chest contained the personal belongings of a seaman, Alan Fielding. There were books, clothing and photographs, together with letters which the seaman had once received from his wife.

练习感悟：
听原音的时候听到there was a tremendous excitement on board，觉得奇怪，为什么会加一个a，看了下文本也没有a；查了下词典，excitement居然都可数跟不可数两种用法。作为可数时，表示令人兴奋的事情~~
[C] (formal) something that you find exciting
• 令人激动(或兴奋)的事:
»The new job was not without its excitements.
这个新工作并非枯燥无味。
所以在这个句子中，应该是作为不可数来用的，不能加a，因为是a feeling of being excited, 不是an event；那到底是我听错了还是原文读错了呢？
