定語從句的語法解析

一、選準關係代詞和關係副詞

在定語從句中，關係代詞或關係副詞都代替先行詞在從句中充當一定的成分，如果該從句中缺少主語、表語、賓語或定語，就要用關係代詞來連接從句；如果從句中缺少狀語，就得用關係副詞來連接從句。例如：

(1) I still remember the days which / that we spent together.

(2) I still remember the days when we worked together.

二、瞭解僅用that 引導限制性定語從句的幾種情況

that 在限制性定語從句中既可指人又可指事或物。在下列情況下，只能用that 來引導定語從句：

1. 先行詞是all , much, few, little, everything, anything, nothing 等不定代詞時。例如：

Is there anything that you want to buy?

2. 先行詞被all, few, little, much, every, some, no等詞修飾或被the only, the very, the same, the last 等限定詞修飾時。例如：

These are all the pictures that I have seen.

This is the very dictionary that is of great help.

3. 先行詞既指人又指物時。例如：

My father and his teacher talked a lot about the things and the persons that they could remember.
