邊句先岩??5該各位幫幫手,,{急}

第一句才對，其實，要知幾時用which，幾時用where，只要拆回原來句子，就比較容易知道。

兩句原句係：
1. Hong Kong is an international commercial centre.
2. Hong Kong is a small island.

將以上兩句independence clauses合併之後，1.Hong Kong 自然變成which來代替。which意思係：香港是什麼？ 香港是一個國際金融中心，香港又是一個小島。where意思係解個度裡面有啲咩？所以強行用where，意思會變成：香港是一個國際金融中心，個度有個小島。而香港係個小島，而唔係裡面仲有個小島，所以用where係錯！

2)Hong Kong,where is a small island,is an inernation commercial centre.岩

There is a spelling mistake. If "inernation" is corrected to "international", then sentence 1 is correct.

1)Hong Kong,which is a small island,is an inernation commercial centre.
