Hi, これ、それ、あれ、どこ mean This, that, that over there and which respectively, while この、その、あの、どの mean this... that..., that... over there and which.... The difference is that with の words, you have to attach a noun. Let's see some examples: これはわたしのさいふです. This is my wallet このさいふはわたしの（さいふ）です. This wallet is mine (my wallet) ここ、そこ　and あそこ、どこ mean this place, that place, that place over there, which place?. So, you use them to describe placeses. Example: あそこにマクドナルドがあります　There is a McDonalds over there. So, you coud say このはなはきれいです This flower is beautiful それはなんですか What's that? どこにいきますたか Where did he/she/you go? あそこでにいきました　I/we/she/he/you went to that place over there. I hope it helps you がんばってね！

訂正<ていせい>correction ありがとう→よろしくおねがいします。I hope you will take care of me.＝Thanking you in advance. To say ありがとう is strange because you haven't known whether someone gives you a favor. It might be a correct expression in English. But in Japanese, we don't say "ありがとうThank you" before we know someone gives us a favor. 回答<かいとう>answer あそこにあるかさ（the umbrella over there）／あのかさ（that umbrella）／あれ（that）　は　だれのですか。 Whose is the umbrella over there / that umbrella / that?

あの,あれ,あそこ あの　a noun is need after "あの". 　あの本　あの木　あの人 あの人たち あれ = "that" あそこ　= there "over there" far place.
