問下關於英文句子文法既問題

I have been dating Nancy since 3rd February 2014. ~ Present perfect continuous tense
We always went to Causeway Bay in the past weeks. ~ Past simple tense
句子文法無錯

Comment:
為什麼有些香港英語老師認為 always只應用在 present tense?

有一回答者這樣說:
“所以能用always和present tense”
“假如你想強調「每一次都是」亦不能用always”

我自己認為 always 是 adverb of frequency, 這類副詞不受 ”什麼時侯” 限制
可應用在 past tense, present tense 與 future上

過去:~
“I always thought they'd get married some day, but they never did.”
~ from Merriam-Webster Dictionary

“I always thought that I would have children eventually.”
~ from Cambridge Dictionary

He always wanted a room of his own.
~ from 英漢字典

He wasn ' t always a butler.
~ from Yahoo字典

將來: ~
I will always remember you.
Thing won’t always go as planned.

劍橋字典上 always = every time, all the time, or forever
在這方面, always 和 every time 沒有太大分別, 理論上, 不需特別用 “every time“去替換 “always”

在另一方面,
或許用 always 間中有一次反常, ( 差不多無例外地), probability is not 100%
every time - probability is 100%
“always” 換了 ”every time”, 意思有少少不同
這不是時態 (time) 問題

字典上是無 everytime 這個字, 應該分開兩個字 every time
不同 everyday (adjective) 和 every day, everyone (pronoun) 和 every one

Britney Spears 有首歌, “Everytime”
2011 年, Robbie Robertson有首歌 “He Don’t Live Here No More”

是否見歌手用便跟隨用? .

Correction:

這不是時態 (Tense) 問題

I have been dating Nancy since 3rd February 2014. 沒有錯
但是
We always go to Caseway Bay in the past weeks.
則不對
因為in the past weeks已經決定所講的內容是過去了的事，因此動詞的時態必須要跟句子表達的時空配合(或反過來講，句子的意義要由動詞的時態來表示)。
所以能用always和present tense.
We went to Causeway Bay in the past weeks.
假如你想強調「每一次都是」亦不能用always而是要更精準地用詞，例如以下寫法：
We went to Causeway Bay everytime we went out in the past weeks.

當然如果你意思只係講由3Feb至今每一次約會(出街)你們都只是去了Casueway Bay，便只需要
We always go to Casueway Bay.
要畫蛇添足或畫龍點睛等修飾便要改句配合句意。

冇錯，寫得啱，係 present continuous tense，意思係你由3/Feb/2014 約 Nancy 約到 24/Feb/2014，仲係約緊佢。下一句與此無關。
