Answer: Affect is a verb that means to have an influence on or to bring about a change in: Does second hand smoke affect the health of all of us? Effect can also function as a verb meaning to execute: Only the president can effect such a change. However, effect is most often used as a noun meaning, result: The drug did not affect the disease, and it had several adverse side effects. Rule of thumb: if you need a verb, nine times out of ten you will used affect; if you need a noun, you will always use effect.
effect有时也可以作动词用，意为“执行”。
例如：Only the president can effect such a change.
但是，effect在大多数情况下都被用作名词，意为“结果”。
例如：The drug did not affect the disease, and it had several adverse side effects.
一个简便的原则就是如果你需要一个动词的话，十之八九选用affect，如果需要一个名词，则通常使用effect.
affect vt.①影响②打动，感动③(疾病)侵袭
词汇辨析affect,effect,influence：
affect常用作动词，effect常用作名词(意为“影响”)：to affect sth.=to have an effect on sth.
effect 作动词时很正式，意为“产生，带来(结果)”，这个产生或带来的结果常常是某人所希望的。
influence指通过行动、榜样等对他人产生潜移默化的影响或作用，注重“影响”的结果。
记忆方法形似词：effect n.影响；effort n.努力
词根记忆af(使)+fect（做）→使人做→影响
effect 43 n.①结果②效果，作用vt.产生，招致
经典例句The effect speaks, the tongue needs not.事实胜于雄辩。
考点提要in effect = in fact 实际上；take effect = come into force 实施，生效；to that effect 大意如此
记忆方法fect(作用)→affect v.影响；effect n.影响
词根记忆ef(出)+fect（做）→做出来→生效，效果
