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有時(shí)也可以作動(dòng)詞用,意為“執(zhí)行”.
例如：Only the president can effect such a change.
但是,effect在大多數(shù)情況下都被用作名詞,意為“結(jié)果”.
例如：The drug did not affect the disease,and it had several adverse side effects.
一個(gè)簡(jiǎn)便的原則就是如果你需要一個(gè)動(dòng)詞的話,十之八九選用affect,如果需要一個(gè)名詞,則通常使用effect.
affect vt.①影響②打動(dòng),感動(dòng)③(疾病)侵襲
詞匯辨析affect,effect,influence：
affect常用作動(dòng)詞,effect常用作名詞(意為“影響”)：to affect sth.=to have an effect on sth.
effect 作動(dòng)詞時(shí)很正式,意為“產(chǎn)生,帶來(lái)(結(jié)果)”,這個(gè)產(chǎn)生或帶來(lái)的結(jié)果常常是某人所希望的.
influence指通過(guò)行動(dòng)、榜樣等對(duì)他人產(chǎn)生潛移默化的影響或作用,注重“影響”的結(jié)果.
記憶方法形似詞：effect n.影響；effort n.努力
詞根記憶af(使)+fect（做）→使人做→影響

經(jīng)典例句The effect speaks,the tongue needs not.事實(shí)勝于雄辯.
考點(diǎn)提要in effect = in fact 實(shí)際上；take effect = come into force 實(shí)施,生效；to that effect 大意如此
記憶方法fect(作用)→affect v.影響；effect n.影響
詞根記憶ef(出)+fect（做）→做出來(lái)→生效,效果
