Even: 加強語氣、驚訝
例：Even when I go to work, I bring food with me. 就連我去工作，我也是會帶著食物。(這句的意思是:我太容易餓了，就連去上班也要帶著食物)
例：Even if I sleep for eight hours, I am still tired the next day. 就算我睡8小時，隔天我還是會覺得累。(這句話的意思是:我平常都睡不到8小時，但就算我睡8小時，還是會累。有點近似於:我不管睡多久都還是會累)
例：Even though I went shopping for the whole day, I still couldn’t find the suit I was looking for. 雖然我逛了一整天，但我還是沒找到我要的那套西裝。(事實就是:我真的花了一整天在逛街，但我竟然還是找不到我要的那套西裝)
since 是「自從」的意思，表示「某個情況從過去的某時間開始，就一直持續著」。
讓我們來看不同情況的例句理解～👇
1️⃣ since 後面接「過去某個時間點」
當介系詞使用時，since 後面會接過去某個特定的時間點。例如：昨天、上週、某年、某月⋯⋯等。
(😉小提醒：記得哦～ since 前面的主要子句要用「現在完成式」，來表示從過去到現在，某情況就一直持續的狀態！)
She has lived in Japan since last year.
她從去年開始住在日本Kevin has been a teacher since 2015.
從 2015年開始，Kevin 就在當老師It has only rained twice since the end of June.
從六月底開始，只下了兩次雨
2️⃣ since 後面接「完整的句子」
當連接詞使用時，since 後面會連接「一個完整的句子」，句子用過去式表示「從過去⋯⋯開始，就⋯⋯」。而 since 前面的主要子句一樣是用「現在完成式」來搭配～👌🏻
We have lived in this house since I was three years old.
從我三歲開始，我們就住在這間房子裡Jack has joined the baseball team since he was a freshman.

since 前面的主要子句也可以搭配「過去完成式」，表達「在過去某時間以前，某情況早就已經持續，但只持續到過去的某個時候，現在可能沒有繼續了」。

他從十二歲時，就已經寫很多歌了Naomi had stayed in different cities since she moved here.

since 也可以代表「既然、因為」的意思，作為連接詞，後面連接一個完整的句子，用來解釋某件事的原因。但這個用法跟 because 稍有不同，since 強調的是「顯而易見、既定的事實、大家已知的情況」。通常這個用法在語氣上也會比較主觀、武斷一些。
Since you can’t answer my questions, I will ask someone else.
既然你無法回答我的問題，我會去問別人Since we still have some time, we can walk around and take some pictures.
既然我們還有點時間，我們可以到處走走、拍些照片We couldn’t see the sunrise very clearly since it was a misty morning.

since 還可以指「從此以後」的意思。
這個用法是把 since 當副詞使用，通常將 since 放在句尾，或放在完成式之間，修飾動作。

她昨晚離開以後，我從此就再也沒見過她His son died two years ago and he has rarely spoken to people since.

ever since 一樣也可以指「此後」，用更強調的語氣來表示「從那之後，某情況就一直持續著」。
句子中，ever since 可以用來接「一個完整的句子」、「過去特定的時間點」，或直接放在「句尾」。
Ever since I was a student, I have wanted to write scripts.
從我還是學生的時候，我就一直想寫劇本Jim has worked for this company ever since he graduated from college.

另外還有個用法是 long since，表示「早就、很久以前就⋯」，常放在動詞之前，修飾動作。

我早就原諒他的所作所為Helen had long since given up her dream.
Helen 很久以前就放棄她的夢想了Jeff had long since gone home before the long weekend started.
在連假開始之前，Jeff 早就回家了
since when 指的是「從什麼時候開始」，口語中常用於問句，用來表示驚訝、憤怒，或是質問的口氣。(小聲說：這句完全就是吵架或嗆人的起手式啦！一開口就戰力十足的那種！😂）
