英語語法對考研英語複習至關重要，很多同學在閱讀以及翻譯過程中，往往受到後置定語的影響，在閱讀中找不準句子的主幹，理解不了句子的意思，影響了對文章的理解，句子的翻譯。所以考生們要重視語法的複習，下面是小編爲大家整理收集的2017考研英語語法定語的常見用法，僅供大家參考。
一、單詞做後置定語
1、以a-開頭的表示狀態的形容詞，一般在句子中當表語成份，但作定語時須後置，類似的形容詞有：alive, asleep, alike, alone, awake, aware, ashamed, adrift, ablaze, absent, afraid, available等如：
Jim was awake at that time.
No man alive is greater than he.
2、部分表示方位、處所、時間副詞作定語。如here, there, above, below, upstairs, downstairs, outside, inside, around, today, nearby 等常作後置定語。如：
The boy there is playing football.
Please answer the questions below.
3、形容詞修飾複合不定代詞時應後置
There is something important to do.
Let’s give her something different to eat,then.
4、else只作後置定語，修飾疑問詞或不定代詞。
Who else can help me?
Tom is taller than everyone else in his class.
5、有些詞既可作前置定語，也可作後置定語。如：
possible, enough, more(另外，附加的)proper
It’s the only solution possible.
二、短語作後置定語
1、介詞短語、副詞短語、形容詞性短語等用作後置定語。
如 China is a great country with a long history.(介詞短語)
The girl in the red hat is my younger sister.(介詞短語)
You’d better ask the policeman over there.(副詞短語)
The basket full of fruits belongs to the beautiful girl.
(形容詞性短語)
2、不定式用作後置定語。如：
I have a lot of work to do today.
He told me his plan to start a company.
The building to be built was designed by Mr Wang. =The building which will be built was designed by Mr Wang. (相當一個定語從句)
If I have the chance to go abroad I’ll never let it go.
3、分詞短語作定語。單個分詞一般作前置定語，而分詞短語作後置定語，此時可以轉化相應的定語從句。
The man standing there is our English teacher.(現在分詞短語作定語)
The Greens have a daughter called Kate.(過去分詞短語作定語)
The building being built was designed by Mr Wang.
The young man waving to me is a friend of mine.
現在分詞作後置定語與修飾的名詞是主動關係,過去分詞作後置定語與修飾的名詞是被動關係。
