特殊疑问词在引导定语从句时,通常用于询问或描述名词或代词的特定方面。这些疑问词包括:who、whom、whose、what、which和where。当特殊疑问词作为定语从句的引导词时,它们在从句中通常充当状语的角色,有时也称为关系副词。
例如:
What可以引导定语从句,并在从句中充当主语、宾语或表语。例如:
The book that you gave me is very interesting.
Who可以引导定语从句,并在从句中充当主语。例如:
The person who called you is my friend.
Whom可以引导定语从句,并在从句中充当宾语。例如:

whose可以引导定语从句,并在从句中充当定语。例如:

Where可以引导定语从句,并在从句中充当状语。例如:

When可以引导定语从句,并在从句中充当状语。例如:

Why可以引导定语从句,并在从句中充当状语。例如:

How可以引导定语从句,并在从句中充当状语。例如:

需要注意的是,某些特殊疑问词如what、whatever、whoever等在引导名词性从句时,可以转换为定语从句,并在从句中充当主语、宾语或表语。
总的来说,特殊疑问词在引导定语从句时,能够提供关于名词或代词的额外信息,使句子更加具体和详细。通过使用这些疑问词,可以使句子的意思更加丰富和明确。
