# 形容詞子句(adjcl的運用)
重點1. 關係代名詞:who>whose>whom>which>whose>which>that>從缺>that (?)
重點2. 關係代名詞所有格:whose(某人的),of which(物)=whose(某物的)
重點3. 準關係代名詞:as,but,than (!)
重點4. 複合關係代名詞:whoever,whomever,whichever,what,whatever (!)
重點5. 關係形容詞:which,what,whatever (!)
重點6. 關係副詞:時間用when,地方用where(where不可當主格),原因用why,方法不可用how

### 何謂句子？:有主詞有動詞
### 何謂子句？:有兩個主詞及動詞,再搭配"連接詞",連接詞分三種:
1.從屬連接詞>>>(adj子句),主要子句
2.關係代名詞>>>(adj子句),主要子句
3.名詞子句的連接詞>>>名詞子句,主要子句
何謂形容詞子句？: 為adj,修飾前面的名詞(先行詞),分熱狗型_____( 句子 )及三明治型_____( 句子 )_____ (?)
### 形容詞子句的必要性？使句子精簡,且更有深度
1. 形容詞子句:由關係代名詞開頭(有八個),又叫(關係子句),用來形容前面的 **_先行詞_** (幫我底線)（先行詞一定為名詞）
2. 先行詞:其位置在於 **_主要子句_**,先行詞可為主要子句的主詞,受詞,或是受詞補語
3. 關係代名詞的詞性兼具 __連接詞__ + __代名詞__ ,所以可以用來連接過多繁雜的句子
4. 合併兩個句子的口訣:
A.) ***刪掉第二個意思相同的名詞(配合中文***
B.) ***口訣:沒有主詞用主格;沒有名詞所有格;主詞動詞用受格***
6. 關係代名詞有哪些:

| 先行詞 \三格| 主格+V | 所有格+N | 受格:V+O;介+O |
| ------------| ------ | -------- | ------------- |
| 人 | who不等於whom | whose | whom=(who) |
| 物 | which | whose | which |
| 人與物 | that | 從缺 | that |

## 一定要用 that :

疑問詞之後；最高級；量詞（all,no,every,any,the only,the same,the very)；序數

**例句**

* <font color="#f00">疑問詞之後：</font>
Whether he will come to our party is the question that struggles us a lot.
* <font color="#f00">最高級</font>：
He is the best boy in the class that won the championship in the Math contest.
* <font color="#f00">量詞</font>：
He is the very boy that was awarded by the mayor for winning the Math contest.
* <font color="#f00">序數</font>：
He is the last boy that turned in his assignments.

## 一定不可以用that：

介詞之後；非限定用法；逗點之後；one, those, people (通常不用that)
口訣:<font color="#f00">**戒指價格只有一個點**</font>

**例句:**

* <font color="#f00">介詞之後</font>：<br>The house which he lived in 10 years ago has been destructed.

* <font color="#f00">非限定用法(就是已經只有"only one"的狀態)</font>：<br>I have a sister, who lives in Tibet.

* <font color="#f00">one, those, people：</font>
1. The ones who are truly dedicated to their craft often find the greatest success in their chosen fields.
2. God helps those who helps themselves. (天助自助者)
<font color="#f00">(文法上people可以用that, 但通常是習慣用who)</font>

* <font color="#f00">逗點之後</font>：<br>The food served by the restaurant, which I recommanded to you last week, is of geat delicacy.
