高三英语教案 难以捉摸的冠词
冠词是英语中的特有的词类。由于汉语中没有与之对应的词，学生对其用法感到难以掌握，所以高考英语在短文改错中对冠词的考查几乎年年都有。

●案例探究
1.Each player must obey captain, who is the leader of the team.
解析：此题为五星级题。captain 前面加the。如chairman, captain, monitor ,manager这类表示职位的名词，前面一般为零冠词，但如果这类职务指的是某人，前面要用定冠词。
e.g. We elected him monitor.
He is the monitor of our class.
2.I was about to rush out of the train station when a well-dressed old man took me by my arm.
解析：此题为四星级题。把my 改成the。take sb. by the hand \\arm 为固定搭配。在固定句型hit sb. in the face,strike sb. on the head ,take sb. by the arm等中，身体各部位前一定用定冠词the。
3.Good health is person’s most valuable possession.
解析：此题为四星级题。在person’s 前加a。person 是可数名词，又是第一次提到，单数前应加不定冠词。
