Affect and effect are different in meaning, though frequently confused. Affect is chiefly used as a verb and its main meaning is ‘to influence or make a difference to’, as in the following example sentences:

Affect一般用作動(dòng)詞，其含義為：影響/改變，如下面例句所示：

The weather will affect my plans for the weekend.

天氣狀況會(huì)影響我周末的計(jì)劃。

Effect, on the other hand, is used both as a noun and a verb, although is more commonly used as a noun. As a noun it means ‘a(chǎn) result or an influence’, as in:

另一方面，Effect一般情況下用作名詞，但也可以用作動(dòng)詞。作為名詞它表示：影響/結(jié)果。例如：

Move the cursor until you get the effect you want.

鍛煉可帶來的益處是有據(jù)可查的。

Over time the effect of loud music can damage your hearing.

長(zhǎng)期聽大音量的音樂會(huì)損害你的聽力。

Effect作為動(dòng)詞，其含義為：產(chǎn)生/達(dá)到目的。這個(gè)用法一般用于正式的語境中，在日常場(chǎng)合中較少使用。

Growth in the economy can only be effected by stringent economic controls.

只有通過嚴(yán)格的經(jīng)濟(jì)控制才能實(shí)現(xiàn)經(jīng)濟(jì)增長(zhǎng)。

The new policies did little to effect change.

這些新政策幾乎沒有產(chǎn)生有效的改變。
