The safety of ships at sea does not depend only on the arrangements made in the ships themselves. Dangerous coasts and rocks may be seen in the daytime,【C1】______they are a threat to safe navigation at night. Lighthouses are therefore erected at such places to【C2】______sailors of the danger. Modern lighthouses are put up at all dangerous places near the courses【C3】______by ships. On some rocky coasts several lighthouses may be built not far from each other, and【C4】______the sailors on a ship may know which is which, they have【C5】______arrangements of lights. One lighthouse will give a single flash at regular【C6】______, another may give two flashes; a third may give two followed by one; and so on. 【C7】______watching the lights the navigator is able to decide exactly where he is, and he can set his 【C8】______with confidence. In the approaches to some ports two continuous lights are set up, one above【C9】______but some distance behind; when they appear from the sea one above the other, the ship is on the right course; but if they do not, the captain knows that he is【C10】______his course and likely to strike a rock or the bottom of the sea. [br] 【C7】
选项
A、On
B、After
C、With
D、By
答案
D
解析
根据句意,本题应选择一个表示方法、手段的介词,D项By意为“靠;通过”,符合句意,因此是正确答案。A项On后接动名词时表示时间,意为“在……后立即”;B项After也表示时间,它们均与句意不太相符;C项With不可直接接动名词,因而不可用在本句。
