    ? Revealing Coloration 00:45 seconds
    ? Many animals use coloration to protect themselves from predators.
    ? One defensive strategy involving the use of coloration is what is known as revealing coloration.
    ? Animals employing this strategy have an area of bright color on some part of their body, this bright color is usually hidden from predators’ view. When approached by a predator, the animal suddenly reveals the area of bright color, this unexpected display of color startles or confuses the predator and provides the would-be-prey with an opportunity to escape.

    記Title:
    由于task 4的閱讀主要是關(guān)于某一個(gè)科學(xué)術(shù)語(yǔ)的解釋和說(shuō)明,考生在開(kāi)始閱讀的第一秒鐘就應(yīng)該迅速在紙上紀(jì)錄下閱讀的題目——即科學(xué)術(shù)語(yǔ)本身。
    記定義:
    常見(jiàn)的表示定義的提示詞有 refer to, known as, is, is called, etc.

    文本分析
    Title:
    Revealing Coloration
    考生對(duì)Coloration一詞較熟,可預(yù)測(cè)段落解釋重點(diǎn)放在Revealing上。
    定義:
    ?中重復(fù)出現(xiàn)了標(biāo)題Revealing Coloration,并且有非常明顯的提示詞known as 。結(jié)合內(nèi)容,動(dòng)物保護(hù)色是動(dòng)物進(jìn)行自我防御的一種策略。因此,該句是定義句。
    注意點(diǎn):
    很多考生認(rèn)為定義句一般出現(xiàn)在段落開(kāi)頭,但?中指出許多動(dòng)物用顏色作為保護(hù),以預(yù)防捕食者的襲擊。這屬于背景敘述,不是定義句。
    ?中是對(duì)動(dòng)物保護(hù)所采取的strategy的的具體描述,因?yàn)閺木漭^長(zhǎng),考生應(yīng)該對(duì)內(nèi)容加以概括或適當(dāng)舍棄。
