　　在托�？谡Z考試中，綜合口語部分一般是由聽力內(nèi)容和閱讀內(nèi)容組成。對于閱讀內(nèi)容考生應(yīng)該注意些什么呢?下面是小編為大家整理收集的關(guān)于生物學(xué)科實例的相關(guān)內(nèi)容，希望對大家有所幫助。

　　標(biāo)題：❶ Revealing Coloration 00:45 seconds

　　❷ Many animals use coloration to protect themselves from predators. ❸ One defensive strategy involving the use of coloration is what is known as revealing coloration. ❹ 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.

　　關(guān)鍵點(diǎn)

　　記Title:

　　由于task 4的閱讀主要是關(guān)于某一個科學(xué)術(shù)語的解釋和說明，考生在開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)語本身。

　　記定義:

　　常見的表示定義的提示詞有 refer to, known as, is, is called, etc.

　　注意點(diǎn):

　　若定義過長或者很難確定的時候，考生應(yīng)當(dāng)舍棄該定義,但必須說出閱讀文章中的title.

　　Task 4中的定義句不一定出現(xiàn)在段首，也非常可能出現(xiàn)在段尾或者段中。

　　文本分析

　　Title:

　　Revealing Coloration

　　考生對Coloration一詞較熟，可預(yù)測段落解釋重點(diǎn)放在Revealing上。
