Affect and effect are two words that are commonly confused.

Affect is usually a verb (action); effect is usually a noun (thing).

Affect和effect这两个词语经常被混淆。Affect通常用作动词，表示某种行为，而effect常用作名词，表示某事。

Hint: If it's something you're going to do, use "affect." If it's something you've already done, use "effect."

提示：如果某事是你正打算要去做的，那ô用affect;如果某事是你已经做完了的，那ô就用effect。

To affect something or someone.

“影响”某事或某人

Example 1: The noise outside affected my performance.

例1：外面的噪音影响了我的发挥。

Example 2: Staying away so long from office will affect promotion.

例2：长期离职会影响晋级。

The use of "effect" as a verb is what causes the most confusion between these two words.

effect用作动词时，最容易和affect造成混淆。

To have an effect on something or someone.

对某事或某人有“影响”

Note: effect is followed by the preposition on and preceded by an article (an, the)

注意：effect前面一般要有冠词a/the，effect后面通常要加介词on。

Example 1: His smile had a strange effect on me.

例1：他的笑容对我有一种奇怪的影响。

Example 2: Parents worry about the effect of music on their adolescent's behavior.

例2：家长们担心音乐对于其青少年子女行为的影响。
