同学们在平时的学习中，注意定冠词和不定冠词的基本用法、零冠词的使用场合以及冠词的一些习惯搭配很有必要。小编现就考试中常考的、且学生易错的冠词的特殊用法归纳如下：
一、只用定冠词的几种特殊情况：
1.在发明物的单数名词前,既表示特指又表示类指时。例如：
Alexander Graham Bell invented the telephone in 1876.
2.在逢十的复数名词前，表示“世纪的某个年代”。例如：
He began to learn Russian in the 1950 s.
但注意： in one&# 39; s 50 s意为“在某人五十多岁时”。例如：
He looked quite healthy though he was in his 80 s.
3.在姓氏复数名词前用定冠词表示“全家人”或“夫妇俩”，请务必注意谓语动词用复数。例如：
The Turners are sitting at the breakfast table, talking and laughing.
4.在比较级的两种句型中：
1)表示“越……，就越……”时。例如：
The lighter, the better.
The more we think of our life, the happier we feel.
2)表示“两者中比较……”时，用定冠词。例如：
Which is the larger country, Canada or America?
5.在身体部位的名词前。
1)在“动词+ sb.+介词+ the+身体部位名称”的结构中（注意：介词常用 in/ on/ by）。例如：

The ball hit me on the back.
2)在表示“身体某一部位受伤”时（注意：介词用 in）。例如：
He was wounded in the back.
但注意：当表示“以身体某部位为支撑点”时，只可以用 one&# 39; s（注意：介词用 on）。例如：
The baby likes sleeping on his stomache.
He can stand on his head for a long time.
6.当月份、季节被限定性定语所修饰时。例如：

8.在表示“计量单位”的可数名词前（注意：介词用 by）。例如：
