why引導(dǎo)定語從句例句
定語從句（也稱關(guān)系從句、形容詞性從句），是指一類由關(guān)系詞引導(dǎo)的從句，因為這類從句的句法功能多是做定語，所以曾被稱為定語從句，這類從句除了可以做定語之外，還可以充當(dāng)狀語等其他成分，所以現(xiàn)代語言學(xué)多使用“關(guān)系從句”這一術(shù)語。下面是小編為大家整理的why引導(dǎo)定語從句例句，歡迎閱讀！
when，where，why作為定語從句的引導(dǎo)詞，總稱為關(guān)系副詞。下面用句子合并的方法分析它們的使用。
一、where引導(dǎo)的定語從句
請分析下面兩個簡單句：
句①I know a garden.
句②You can find wild strawberries there.
把句②變?yōu)榫洧俚亩ㄕZ從句，句①中的agarden做定語從句的先行詞。在句②中there指句①中提到的agarden也就是定語從句的先行詞，there在句中做地點狀語，因此要用where引導(dǎo)定語從句，代替句②中的there，也就是說there就不能出現(xiàn)在定語從句中了。由此得到句③I know a garden where you can find wild strawberries.
句②還可以寫作句④You can find wild strawberries in it(it指句①中的garden，“在花園中”要使用介詞短語in the garden)。把句④變?yōu)榫洧俚亩ㄕZ從句，因為it做介詞in的賓語，先行詞是agarden，指物。在這種定語從句中介詞常常提到定語從句的開始，這時關(guān)系代詞只能使用which替代it，it就不能在定語從句中出現(xiàn)了。由此得到句⑤即：I know a garden in which you can find wild strawberries.
請把下面每組的兩句話合并為一句，把第二句話變?yōu)榈谝痪涞亩ㄕZ從句。
第一組：
This is the village.
I was born there.
→This is the village where I was born.
第二組：
The lab is not far from here.
The chemist often does experiments there.
→The lab where the chemist often does experiments is not far from here.
二、when引導(dǎo)的定語從句
請分析下面兩個簡單句：
句①We shall remember the days.
句②We studied together then.
把句②變?yōu)榫洧俚亩ㄕZ從句，句①中的the days做定語從句的先行詞。在句②中then指句①中提到的the days，也就是定語從句的先行詞，then在句中做時間狀語，因此要用when引導(dǎo)定語從句，代替句②中的then，也就是說then就不能出現(xiàn)在定語從句中了。由此得到句③We shall remember the days when we studied together.
句②還可以寫作句④We studied together during the days.(介詞短語during the days含義為“在這些日子里”)。把句④變?yōu)榫洧俚亩ㄕZ從句，因為the days做介詞during的賓語，先行詞是the days，指物，在定語從句中介詞during提前，用關(guān)系代詞which替代the days，the days就不能在定語從句中出現(xiàn)了。由此得到句⑤We shall remember the days during which we studies together.
請把下面每組的兩句話合并為一句，把第二句話變?yōu)榈谝痪涞亩ㄕZ從句。
第一組：
Ive always longed for the days.
I should be able to be independent then.
→Ive always longed for the days when I should be able to be independent.
第二組：
There are moments.
I forget all about it then.
→There are moments when I forget all about it.
三、why引導(dǎo)的定語從句
請分析下面兩個簡單句：
句①He wanted to know the reason.
句②I was late for the reason.
把句②變?yōu)榫洧俚亩ㄕZ從句，句①中的the reasons做定語從句的先行詞。因為the reason做介詞for的賓語，先行詞是the reason指物，在定語從句中介詞for提前，用關(guān)系代詞which替代the reason，the reason就不能在定語從句中出現(xiàn)了。由此得到句③He wanted to know the reason for which I was late.
注意：在定語從句中當(dāng)先行詞為the reason(s)，定語從句由for which引導(dǎo)時，可以用why代替for which。由此我們得到句⑤He wanted to know the reason why I was late.
請把下面兩句話合并為一句，把第二句話變?yōu)榈谝痪涞亩ㄕZ從句。
The reason is not very convincing.
He came for the reason.
→The reason why he came is not very convincing.
The reason for which he came is not very convincing.

當(dāng)使用why引導(dǎo)定語從句時，需要注意以下幾個關(guān)鍵點：
1. 先行詞限定
先行詞必須是reason：why引導(dǎo)的定語從句中，其先行詞通常且只能是reason，表示“原因”的名詞。例如，“I dont know the reason why he looks unhappy today.”（我不知道他今天看上去不高興的原因。）
2. 關(guān)系詞作用
why作原因狀語：在定語從句中，why作為關(guān)系副詞，起到原因狀語的作用，用于說明先行詞reason的具體內(nèi)容或原因。
3. 句式結(jié)構(gòu)
定語從句結(jié)構(gòu)：why引導(dǎo)的定語從句遵循“先行詞（reason）+ why + 從句”的結(jié)構(gòu)。從句部分是對先行詞reason的具體說明或解釋。
4. 替換與省略
可替換為for which：在某些情況下，why可以替換為for which，兩者在定語從句中均表示原因狀語。例如，“The reason, for which I come here is that I want to get your help.”（我來這里的原因是我想得到你的幫助。）
省略情況：在特定語境下，why引導(dǎo)的定語從句中的why有時可以省略，但這種情況較為少見，且需確保省略后句子意思仍然清晰。
5. 區(qū)分同位語從句
與同位語從句的區(qū)別：同位語從句用于解釋說明前面的名詞（如idea, fact, news等）的具體內(nèi)容，而定語從句則是對先行詞進行修飾限定。當(dāng)why引導(dǎo)同位語從句時，其前面的名詞通常帶有“疑問概念”，且why不能省略。例如，“I have no idea why he was late for class.”（我不知道他為什么上課遲到。）這里的why引導(dǎo)的是同位語從句，解釋說明no idea的內(nèi)容。
6. 語義理解
理解定語從句的語義：在理解why引導(dǎo)的定語從句時，需要明確從句部分是對先行詞reason的具體解釋或說明，而非對reason的簡單重復(fù)或無關(guān)描述。
