even though, even if,though,although的用法和区别
though,although,even though 这些连词均可表示“虽然,尽管”之意.
though和although在意义上几乎毫无区别,但在习惯用法上这两个词仍有以下一些差异：
1.though可引出倒装语序的让步状语从句,although 则不能.
2.though可与even连用,although则不能；在as though结构中,只用though,不能用although.
3.though可以置于从句末,而although则不能. 4.引出省略句时,通常用though.
although与though在意义上相似,但文体上是比较正式用词,语气比though强.
even though（＝even if）,意为“即使”,引导让步状语从句.though也引导让步状语从句,意为“虽然”；even though有退一步设想的意味,与though不同.though引导的句子所说的是事实,even though引导的句子所说的则不一定是事实.例如：He will not tell the secret even though（even if）he knows it．
即使他知道这个秘密,他也不肯说出来.He will not tell the secret though he knows it． 他虽然知道这个秘密,但他不会说出来.
even though 和 even if 均可用于引导让步状语从句，其细微区别是： 1. even if 引导的从句是往往是假设性的，相当于汉语的“即使”“纵然”“就算”“哪怕”。如：
They’ll stand by you even if you don’t succeed. 即使你不成功，他们也会支持你。
Even if I have to walk all the way I’ll get there. 即使我得一路走着去，我也要走到那里。
Even if it rains tomorrow, we won’t change our plan. 即使明天下雨，我们也决
不改变计划。
For my part, I plan to go to the party even if you decide not to go.
至于我，
即使你决定不去参加晚会我也会去的。
Even i
f you saw him pick up the money, you can’t be sure he stole it. 就算
你看见是他拾起的钱，你也不能肯定钱就是他偷的。
正因为
even if
从句的内容通常是假设性的，所以有时还可用于虚拟语气；这样用的
even if
与单独使用的
if
比较接近。如：
Even if he had the money, he wouldn’t buy it. 他即使有钱也不会买它。
I would have married her even if she had been penniless.
即使她身无分文，我
也会和她结婚。
2.
even though
引导的从句内容往往是真实的，主要用于引出不利用于主句情况的信
息，相当于汉语的“尽管”“虽然”。如：
He went out even though it was raining.
尽管在下雨，他还是出去了。
Even though it’s hard work, I enjoy it. 虽然工作艰苦，我还是很喜欢。
He’s the best teacher even though he has the least e
xperience.
他尽管经验最
少，但教得最好。
Even though I didn’t know anybody at the party, I had a nice time. 尽管这次
聚会上我谁也不认识，我也玩得挺痛快。
这样用的
even
though
与
though
或
although
的意思比较接近，许多时候可以互换（注
意：英语可以说
though
和
even though
，但不能说
even although
）。如：
Even though [Thought, Although] I felt sorry for him, l was secretly pleased
tha t he was having difficulties.
虽然我为他感到惋惜，但对他的困难却暗自高兴。
Even though [Thought, Although] we all tried our best, we lost the game.
虽
然我们已尽了最大的力量，但还是输了。
3.
不过，在实际语言运用中，
even if
与
even though
有时也可不加区别地混用。如：
Even if [Even though] she laughs at him, he likes her.
尽管她嘲笑他，他还是
很喜欢她。
We
thoroughly
understand
each
other,
even
if
[even
though]
we
don’t
always
agree.
我们彼此非常了解，虽然有时候也有一些分歧。
even if 即使
even though 即使
despite 为介词 意指 in spite of: 不管
后面接名词结构
even if (=even though)
though,although,even if (though)均可引导让步状语从句,但在侧重假设或推断时要用though或as if(though),例如：
Although it rains heavily,we shall still go out
上句中although应改为even if (though)或though.
再如：Though(Even though) everyone deserts you, I will not.
