单选题 Seeing the wreck for the first time, under the great arc of a sunny sky on that level shore, I was initially impressed by its remoteness. Here was the focus of those weeks of discussion, of seemingly endless careful planning: a slightly projecting, elongated outline. The warmth of the day meant that many holiday-makers were about, and our equipment rapidly attracted them to the site, unmistakable with its brilliant orange marker, each attached to a steel post. These posts marked off the four corners of our working area, and were linked by a rope to keep it clear of curious sightseers. Many structural features of the wreck which would normally have been visible were obscured by the sand, which was not only right up to but even above the upper gun deck. We went to work immediately when the first low tide made a start possible, and set up our basic survey line running down the middle of the wreck from bow to stern. As we set about measuring the sides of the ship in their relation to survey line, the "Amsterdam" emerged as a vessel of substance, and more so when the members of the team had scoured her aged timbers free from mussel shells and seaweed. All this activity attracted an increasing number of sightseers, whose interest was natural and welcome, since the more people who were moved to understand what we were about, the better it was for archaeology in general and for the future preservation of the " Amsterdam" in particular. However, there were also predatory souvenir hunters who were most disappointed by our merely taking elaborate measurements, with no apparent intention of digging up more objects.

单选题 Seeing the wreck of the "Amsterdam", the author was impressed by______.

【正确答案】 A

【答案解析】解析：事实细节题。根据题干中的seeing the wreck和was impressed by将本题出处定位于文章第一段第一句。该句提到，作者第一次见到阿姆斯特丹号沉船残骸时，首先留下深刻印象的是它年代的久远。题干中的seeing the wreck和，was impressed by为文中信息的再现，其后内容为本题答案的依据。remoteness意为“偏僻，遥远”。[A]项较准确地表达了原文的意思，故答案为[A]项。

单选题 According to the passage, the holiday-makers on the beach were______.

【正确答案】 D

【答案解析】解析：事实细节题。根据题干中的holiday-makers将本题出处定位于文章第二段第一句。该段提到，施工范围的四角插着有橙色标志的钢杆，用绳子圈起来，以阻挡好奇的观光者。[D]项是对原文的同义转述，故为答案。

单选题 The word "obscured" in the passage probably means______.

【正确答案】 B

【答案解析】解析：词义理解题。根据题干中的obscured将本题出处定位于第三段第一句。该句提到，沉船残骸在正常情况下本应可见的结构特点被沙子“obscured”，这些沙子不仅到达了炮甲板，甚至没过了它。由此推测， “obscured”指本应可见的东西变得看不清了，即“使变得模糊”，故答案为[B]项。

单选题 We are told that work on the wreck was made difficult by______.

【正确答案】 C

【答案解析】解析：事实细节题。第二段提到，温暖的天气意味着大批度假者的到来，而“我们”的设备会迅速将他们吸引到残骸所在地，考古人员设置了绳索防止他们进入施工范围，由此可知，大量的度假者会加大沉船上的工作难度，故答案为[C]项。
