20分non-defining relative clauses20分

Hi,
What is a non-defining clause?
NON-DEFINING RELATIVE CLAUSES
The information in these clauses is not essential. It tells us more about someone or something, but it does not help us to identify them or it.

The textbooks,which the students like,have lots of helpful examples.
Even you take out the yellow part, you still see a complete sentence.
**The textbooks have lots of helpful examples.*****
" which the students like" <--------- to give extra information on the textbooks ONLY.
My students,who are all adults,are learning English to get a better job .岩
__who are all adults <------------( extra info)______________________________________________
this girl is called sandy.this girl is wearing a red hair-clip.<--Your sentence
Ans: This girl, who is wearing a red hair clip, is called Sandy.
who is wearing a red hair clip <------------ (extra info)

Note: Yellow parts are what you call" non-defining clauses".
We ONLY use them to give extra information.***************
Let's look at the definition again:
The information in these clauses is not essential. It tells us more about someone or something, but it does not help us to identify them or it.
Compare:
1) We mainly want to know( the textbooks have lots of helpful examples.)<----- important part.
2) My students are learning English to get a better job.<------Important part. ( That's what we want to know.)
3) This girl is called Sandy.( We want to know her name.
Who cares if she is hairless or she is wearing anything?)O_O
I did my best! I hope you understand it.

See youO_O

Relaive Clause 係將兩句句子合為一句
首先分主句(較重要)及子句(無較重要),將子句的名詞轉為Relative Pronoun, 插入主句相關名詞後面

Relative Pronoun
人(subject) - who
人(object) - whom
死物(subject/object) - which
人 / 死物(subject/object) - that
人的(whose)
死物的(The XXX of which)

(The XXX of which)學校好少教, 相信你其他都識,我順便講
I bought the clock. The leg of the clock was broken.
I bought the clock (the leg of which) was broken.

例子
I go to (shool)(主句 - 較重要)
(It) is on top of the hill (子句 - 無較重要)
I go to school which/that is on top of the hill.
I go to school which/that (it) is on top of the hill. (錯 - It 已轉為Relative Pronoun which，因此不需要寫IT)


non-defining clauses 同defining clauses 的分別
簡單分別就係(指名道姓)就係non-defining clauses, 要加comma
不是(指名道姓)就係defining clauses, 不加comma

Kate’s parents, who live in New Zealand, are both teachers. - 指名道姓(Kate) , non-defining clauses , 要加comma )

His parents who live in New Zealand are both teachers. - 不是指名道姓(His) , defining clauses , 不加comma )

I met a friend. I hadn’t seen my friend for a long time.
I met a friend (whom/that - 可以省略) I hadn’t seen for a long time.
(defining clause) 做 限定用法的關係代名詞，為受格(object)的時候，可以省略(omit)

請特別僅記:
當(non-defining clause) 做 限定用法的關係代名詞，為受格(object)的時候，絕對不可以省略(cannot omit)
I met Peter, (whom/that - 不可以省略), I hadn’t seen for a long time.


講悉你的問題, 最令你困擾是邊句做主句,邊句做子句
例子:
the shop is located in Wan Chai.
It sells designer clothes at discount prices.

若你以第一句作為主句(即較重要),第二句作為子句(無較重要)
便可寫成
The shop (which sells designer clothes at discount prices) is located in Wan Chai.

相反若你以第一句作為子句(無較重要),第二句為作主句(即較重要)
便可寫成
The shop (which (is - 你寫漏) located in Wan Chai sells designer clothes at discount prices.

其實你想邊句做主句,邊句做子句,由(作者決定)
你的句子兩句都啱!
Frank Zappa, who was one of the most creative artists in rock 'n roll, came from California.(啱)

Frank Zappa, who came from California,was one of the most creative artists in rock 'n roll. (啱)

由於做Relative Clause 往往有2個答案, 若無特別指明第二句做主句, 一般以第一句做主句

希望幫到你!
