分不清引导词在定语从句中所充当的成份。

充当定语从句引导词的有关系代词和关系副词，但许多学生在做题时常常只注意其所修饰的先行词，而区分不清关系代词that,

which,

who等和关系副词when,

where,

why等的作用。常犯错误如下：（1）I

will

never

forget

the

day

when

Ispent

with

my

boyfriend.（2）The

reason

why

he

gave

us

is

just

an

excuse.（3）This

is

a

shop

where

sells

the

children’s

toys.2

、不知道关系代词不仅指人，也可以指物。常犯错误如下：I

live

in

a

room

which

windows

face

south.3、不知道如何选用“介词+关系代词”结构中的介词。常犯错误如下：In

the

dark

street,

there

was

no

person

on

whom

she

could

turn.4、忽视句子中逗号和句号的功能。常犯错误如下：He

has

two

brothersboth

of

whom

are

doctors.5、只知道在非限制性定语从句中不能用

，而不注意前面所修饰的先行词。常犯错误如下：WangMei

has

two

sisters,both

of

which

are

nurses.从事英语教学多年，感触
