有野問..

1. the 係指specific既人樣物件或是一個人, 呢題係指某地方既人

2.唔加the係因為冇指明邊個beach

其實1,2題加唔加the我自己覺得都冇咩所謂,讀起黎都幾順口

3. 應該唔可以加, 因為加who, which都係relative clause,如果你加左who呢,成句會變左一句冇意思既句子,意思即係你想搵一個指定既policeman ,個policeman係幫過你搵你既失袋,但係由此可以睇到呢句係1句唔完整既句子,之後就要加多一個main clause,例如係this policman who helped me find my lost bag, is my uncle, who helped me 係1句可有可冇既句子,最主要想講既係he is my uncle

而冇加who既意思係1句普通statement,意思係那個policeman幫過我搵番個失袋

所以加左who就會變左1句唔完整既句子, 冇加who就係1句完整句子

#1 Correct.

#2
Either
Some of the beaches are covered with all kinds of rubbish.
or
Some beaches are covered with all kinds of rubbish.

Some of beaches is wrong.

#3唔可以加個who 係 helped 前面e.g. I thanked the policeman who helped me find my bag.e.g. The policeman who helped me find my bag is an inspector.

the 是『指明』的物件(有限制範圍)
1.Some of the residents是指明(那所大廈)的住戶;
2.Some of beaches是冇指明哪些沙灘

唔緊要嫁!有 The 同無 The 都岩嫁!
