even though 和 even if 均可用於引導讓步狀語從句，其細微區別是：
1. even if 引導的從句是往往是假設性的，相當於漢語的「即使」「縱然」「就算」「哪怕」。如：
They』ll stand by you even if you don’t succeed. 即使你不成功，他們也會支持你。
Even if I have to walk all the way I』ll get there. 即使我得一路走著去，我也要走到那裡。
Even if it rains tomorrow, we won’t change our plan. 即使明天下雨，我們也決不改變計劃。
For my part, I plan to go to the party even if you decide not to go. 至於我，即使你決定不去參加晚會我也會去的。
Even if you saw him pick up the money, you can’t be sure he stole it. 就算你看見是他拾起的錢，你也不能肯定錢就是他偷的。
正因為even if從句的內容通常是假設性的，所以有時還可用於虛擬語氣；這樣用的even if 與單獨使用的if比較接近。如：
Even if he had the money, he wouldn’t buy it. 他即使有錢也不會買它。
I would have married her even if she had been penniless. 即使她身無分文，我也會和她結婚。
2. even though 引導的從句內容往往是真實的，主要用於引出不利用於主句情況的信息，相當於漢語的「儘管」「雖然」。如：
He went out even though it was raining. 儘管在下雨，他還是出去了。
Even though it’s hard work, I enjoy it. 雖然工作艱苦，我還是很喜歡。
He’s the best teacher even though he has the least experience. 他儘管經驗最少，但教得最好。
Even though I didn’t know anybody at the party, I had a nice time. 儘管這次聚會上我誰也不認識，我也玩得挺痛快。
這樣用的even though與though或although的意思比較接近，許多時候可以互換（注意：英語可以說though和even though，但不能說even although）。如：
Even though [Thought, Although] I felt sorry for him, l was secretly pleased tha t he was having difficulties. 雖然我為他感到惋惜，但對他的困難卻暗自高興。
Even though [Thought, Although] we all tried our best, we lost the game. 雖然我們已盡了最大的力量，但還是輸了。
3. 不過，在實際語言運用中，even if與even though有時也可不加區別地混用。如：
Even if [Even though] she laughs at him, he likes her. 儘管她嘲笑他，他還是很喜歡她。
We thoroughly understand each other, even if [even though] we don’t always agree. 我們彼此非常了解，雖然有時候也有一些分歧。
