在三种英语从句中，名词11从句与副词从句用得较多，错误也较少。形容词从句用得较少，但却易犯错，尤其是下列四种错法：

㈠重复形容词中的宾语。例如：

*① The essay which John wrote it yesterday got a good grade.

*② Do you know the name of the man whom the police are looking for him?

在①里的形容词从句中的"it"和②里的"him"都是重复的宾语，因为这两个宾语已经由关系代词"which"和"whom"接管了。因此，"it"和"him"是多余的，必须去掉。

㈡关系代词或关系副词不对。例如：

*③ This is the dog who ate up the food.

*④ Do you know the time which we must resume work?

③里的关系代词"who"和④里的"which"都错。③里的先行词是一种动物，关系代词里"which"或"that"才对。

④里的先行词是“时间”，应该用关系副词"when"才可。

㈢形容词从句修饰的对象不符。例如：

*⑤ Malcolm finished the work and then left the office which was well-planned.

这里的形容词从句"which was well-planned"，应该修饰名词"the work"，不是"the office"，因此犯了修饰的对象不符之错。容易的改正方法，是使这个从句紧扣在先行词"the work"后面，即：

⑥ Malcolm finished the work which was well-planned and then left the office.

这样的改正虽然符合语法，但句子显得头重脚轻，失去平衡;对是对，但是不好。我建议重整从句，以臻“既对且好”之境。试比较 7(a)，(b)和(c)：

⑦a. Malcolm left the office after he had finished the work which was well-planned.

b. Malcolm left the office after having finished the work which was well-planned.

c. Malcolm finished the well-planned work and then left the office.

三句中，⑦(c)一气呵成，短小精悍，是上选。此外，⑦(c)把形容词从句节缩为合成形容词(compound adjective)，使句子简练有力。这点足以证明节缩句的好处。关于节缩方法，以后再谈。在了解节缩法之前，千万不要随便尝试，以免犯错。例如： *⑧ A sentence is made up of a subject and a predicate is called a simple sentence.

⑧里的"is made up of a subject and a predicate"是形容词从句"which is made up of a subject and a predicate"的节缩体，但是错了。

根据形容词从句的缩略规则，如果形容词从句是被动式的话，就要把关系代词和助动词"be"一齐去掉：

⑨ Do you like the man who was introduced to you yesterday? → Do you like the man introduced to you yesterday?

⑩ Please fill in each of the blanks which are provided below. → Please fill in each of the blanks provided below.

⑧里的关系代词不见了，但是助动词"is"还在，莫怪整句读起来，有点不顺口;因此要改一改;

A sentence made up of a subject and a predicate is called a simple sentence.

"Though the standard of living is raised, the costs of living are also increasing."
