Yahoo! 知識＋ ： 文章中These and those 好難搞不清

The sentence: The government is preserving the heritages and culture of the city since (these/those) are always the attractions to tourists

I don't know whether these or those should be used in the sentence. 
Either these or those / both of these and those could I use in the above sentence? 

The sentence above always confuses me >>中文these這些those那些, 但這是近定是遠, 分不到, 對話時可以指著物件,知道近遠, 但敍述以上句子究竟heritages and culture是近定是遠, I cannot distinguish their differences.


答：

these

If something happened in the past, the usage of 'that' or 'those' is more appropriate.

On the other hand, we use 'this' or 'these'.

如果句子是用過去式，用‘that’或‘those’，其餘用'this' or 'these'。
