问题     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] 【C4】
选项 A、so that
B、in order that
C、even though
D、now that
答案 B
解析 从上下文看，本句相对于下旬应该是表示目的，句子的意思是说，“为了让船上的水手知道哪座是哪座，灯塔的灯有不同的安排。”A项so that和B项in order that均可表示目的，但so that引导目的状语从句时必须放在主句之后，故用在这里不合适，正确答案应选B。C项even though“尽管”表示让步关系，D项now that“因为，既然”表示原因，它们用在这里均与上下文的意思不符。
