名师点评

1．C。下文表明：你要去的是一个一点儿都不熟悉的城市，说明以前没有去过。故选have never visited。

3．A。文章表明：听了别人的介绍后，你对城市的名胜开始有了一些初步的印象。故选begin。

4．B。根据文意，你对名胜的概况只是听说而已，对名胜的具体位置及如何找到所指的名胜不太清楚。故选clear。

5．C。指代上文出现的interesting places应用them。

6．A。根据句意，前半句是后半句的条件状语从句，应用if引导。

7．D。show sb. sth.意为“把……给某人看”，合符文意，为正确选项。

8．B。根据地图上的位置，你会毫不费力地找到想去的地方。故选no。

9．B。本文是讲如何在一个陌生的城市里找到目的地，而不是找去某个城市的路。故选in。

10．A。做数学题时，你肯定要对题目中所给的信息进行思考。故应选thought over。
