      Key: 1. an → a 2. usually → usual 3. while → when 4. passer-by → passers-by

      5. such → so 6. removing → remove 7.√ 8. surprising → surprise 9. Under → With 10. cover → covered

      答案解析：

      1. 冠词错误。表示浓雾的一天，是泛指，应用不定冠词。foggy是以辅音音素开头，故用a。

      2. 搭配错误。 as usual是习惯搭配，表示“同往常一样”。

      3. 连词错误。用when表示前后两个动作同时发生。

      4. 名词错误。路人应该有很多，要用其复数形式。

      5. 副词错误。此处是“so… that…”结构，应把such改为so。

      6. 搭配错误。在“took great trouble to”中的to为不定式符号，所以后面应该用动词原形。

      7. √

      8. 固定用法错误。to one’s surprise是固定用法，表示“让某人吃惊的是”。

      9. 介词错误。表示“在某人的帮助下”应用“with one’s help”。

      10. 动词时态错误。文章的基本时态是一般过去时。
