问题 The old sailor had never studied navigation, but he had good ________knowledge of it.

选项 A、periodical
B、tropical
C、empirical
D、vertical

答案 C

解析 形容词辨义。本题是修饰knowledge的一个形容词,结合所给的选项:periodical意为“(定期出版的)杂志,期刊,周期性的”,如:learned periodical(学术期刊);tropical意为“热带的,热情的”,如:a tropical plant(热带植物);empirical意为“以经验(或观察)为依据的,经验的”,文中讲老水手虽然没有学过航海,但他有着丰富的经验知识,所以此项符合题意,再如:empirical results that supposed the hypothesis(证明假设成立的经验性结论);vertical意为“垂直的”,如:Walls are usually vertical.(墙通常是垂直的。)
