The meanings ofintense and intensive overlap considerably, but the two are often subtly distinct.When used to describe human feeling or activity,intense often suggests a strength or concentration that arises from inner dispositions and is particularly appropriate when used to describe emotional states:
intense 和 intensive 的意思在相當(dāng)程度上是交叉的， 但是它們經(jīng)常有細(xì)微的差別。當(dāng)用來(lái)描述人的感情或活動(dòng)時(shí)，intense 通常指由內(nèi)在傾向而來(lái)的力量或?qū)Ｐ模?它特別適于用來(lái)描寫(xiě)感情狀態(tài)：
例句：
intense pleasure, dislike, loyalty, and so forth. Intensive
極度的快樂(lè)，極為厭惡，非常忠誠(chéng)等等。 Intensive

is more frequently applied when the strength or concentration of an activity is imposed from without:
更常用于指行為的強(qiáng)度和程度是由外部強(qiáng)加的：
例句：
intensive bombing, training, marketing.
強(qiáng)烈的爆炸，強(qiáng)烈的訓(xùn)練，緊張的營(yíng)銷(xiāo)。

因此Mark`s intense study of German 指馬克自己對(duì)集中的行為負(fù)責(zé)， 而Mark`s intensive study of German 意味著馬克的學(xué)習(xí)計(jì)劃是打算在短時(shí)間內(nèi)涉獵大量?jī)?nèi)容
