该题考查学生准确使用英语的综合能力。做题时候，学生首先需要理顺文章脉络，弄懂文章大意：深夜我在路上行走，后面有脚步声响起。我很害怕开始跑，而我前面的女士，听我的我的跑步声，吓的把手里袋子丢掉，大声尖叫。而走在我后面的人，从我们身边走过时，好奇地看向我们。其次，对照考查方向逐句分析找到错误并且准备修改。1）连接词，...was doing...when...2）词性转换，dark形容词作表语。 3)连接词，as soon as，所以so多余。4) 冠词，person是指代那个在我后面走的人。 5)非谓语用法，carrying作后置定语。 6)动词时态，but前面有did，动词用原形throw。7)介词，with a look of terror on her face 作方式状语。8)代词，作者对着the woman 微笑。 9)连词，the person 与footsteps是所属关系10)代词，这里是指代作者和那个woman，只有两个人，所以用both
