回复：
Dear Young-Ho,
亲爱的Young-Ho，
These are commonly confused words. Although they are spelled differently, they sound - and look - almost the same: affect and effect. But the one-letter difference makes a big difference.
这些是通常容易混淆的单词。虽然它们的拼写有所不同，但是它们听上去和看上去都几乎一样。但是一字（母）之差会带来很大的不同。
Effect
影响
Let us start with "effect," E-F-F-E-C-T. "Effect" can act as a noun or, in rare cases, a verb. As a noun, "effect" means "a change that results when something happens." For example,
我们先来说effect这个单词。它可以充当名词，在极少数情况下也可以充当动词。作为名词，effect的意思是当某事发生时导致的变化。例如：
The movie had a strong effect on my feelings.
这部电影对我的情感产生了强烈影响。
The use of internet sales had a good effect on our business.
网络销售的应用对我们的生意产生了良好的效果。
Another form of the word is the adjective "effective." It means "producing a result that is wanted." Medical experts, for example, tell us:
这个单词的另一种形式是形容词effective。它的意思是“产生预期效果。”例如医学专家告诉我们：
Handwashing is very effective in removing germs.
洗手对清除细菌非常有效。
Affect
影响到
"Affect," A-F-F-E-C-T, is usually used as a verb. "Affect" means "to influence." In other words, affect means to act on or change someone or something. For example:
Affect通常用作动词。Affect是指影响到。换句话说，affect意思是指对某人或某事物采取行动或产生改变。例如：
She has back problems that affect her balance, so she has trouble walking.
她患有背疾，这影响到了她的平衡，因此她行走困难。
Remember our earlier example about the movie having an effect on one's feelings? We could also say:
还记得我们之前提到的电影影响到人的情感的例子吗？我们也可以说：
The movie affected me greatly.
这部电影深刻地影响了我。
In this case, "affect" means to cause strong emotions.
在这种情况下，affect是指引起强烈的情绪。
If you are still confused, just remember this: effect is usually a noun, and affect is usually a verb.
如果你仍然感到困惑，请记住这点：effect通常用作名词，而affect通常用作动词。
And that's Ask a Teacher!
