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 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 experience. 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 that 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是一个常用的副词。该词用法较广，位置较活。现将其用法归纳如下: 一、用在比较级前，加强语气，表示程度。具有still，yet,much的意义，汉语意思为“(比……)更，还要” 这种句型意味着两个被比事物都是怎样，而其中的一个更为怎样。如:This dictionary is even more useful than that one.这本词典比那本更为有用。 This time he did it even better。这次他做得还要好。 二、放在它所强调的词、短语或从句前，用来加强语气，表示“即使，甚至连……都”之意 1.强调名词。Even a child can understand the book.即使小孩也能看懂那本书。 Even the movements of the heart and lungs are greatly reduced.(冬眠动物)甚至连心脏和肺部的运动也大大减少了。 2.强调形容词。Bamboo is so strong that people use it to build houses and even high bridges over rivers。竹子很结实，人们用它建造房屋，甚至在河上架大桥。 The chain was even worthy of the gold watch.这条表链甚至配得上那只金表。 3.强调副词。I have explained everything,but even now she doesn′t understand.我已做了全面的解释，甚至到现在她还不明白。 Even then he would not admit his mistake.甚至那时他还不承认错误。 4.强调数词。Then the need to turn to a dictionary or a reference book,perhaps ten or even twenty times a page,tires him out.后来，每读一页需要查阅词典或参考书10次甚至20次，这就使他疲惫不堪。 5.强调动词。I even forget what my mother said.我连母亲的话都忘了。 I can′t even remember the name of that old friend of mine.我甚至连那位老朋友的名字都记不起来。 6.强调介词短语。He was afraid to go out, even for food.他不敢出门，甚至连食物都不敢去找。 With that man′s permission and even with his help,he seized her and took her away.在那个人的许可下，甚至在他的帮助下，他把她抓走了。 7.强调从句。It happened even as we expected.事情正如我们所预料的那样发生了。 从以上各例可以看出，even的用法不仅广泛而且位置也较灵活。大体上说，它可位于句首，也可位于句中或句末。但是，even在句中的位置不同，全句的意思或重点也有所不同。一般来说，even的位置应靠近它所强调的词语和短语。例如: Even John doesn′t go out in the summer(so certainly nobody else does).即使约翰夏天也不外出(所以别人也不一定外出。) John doesn′t go out in the summer(so he certainly does nothing else).约翰夏天甚至连家门都不出(所以他一定不做别的什么事情。) 三、even和if，even和though可分别组成连词，引导让步状语从句，意思是“即使” Nothing could have saved him even if he had been tended without delay.即使当时他得到了及时的救护，也无法挽救他的生命。 It would not matter even though he should refuse.即使他拒绝，那也没有什么关系。但单独的 even是副词不能引导让步状语从句。 四、even as连用，表示“恰恰在……的时候(just at the same moment as)”的意思。 Even as I started,it began to rain.正当我出发时，天下起雨来了。 She went away even as you came.就在你来的时候，她走了。 本文来源：https://www.wddqw.com/doc/30f52702b9d528ea80c77940.html
