托福閱讀高難度文章長難句實(shí)例解析：熱帶包含更大土地面積

　　原句案例：

　　The tropics contain a larger surface area of land than higher latitudes——a fact that is not always evident when we examine commonly used projections of Earth's curved surface, since this tends to exaggerate the areas of land in the higher latitudes——and some biogeographers regard the differences in diversity as a reflection of this effect.

　　詞匯講解：

　　tropics n. 熱帶

　　projection n. 發(fā)射，投射;

　　exaggerate /?g'zæd??re?t/ v. 夸張，夸大

　　結(jié)構(gòu)劃分：

　　The tropics contain a larger surface area of land than higherlatitudes——(a fact) (that is not always evident) (when we examine commonly used projections of Earth's curved surface), (since this tends to exaggerate the areas of land in the higher latitudes)——and some biogeographers regard the differences in diversity as a reflection of this effect.

　　深度分析：

　　這個(gè)句子的主干就是一個(gè)并列結(jié)構(gòu)，中間被一個(gè)破折號(hào)隔開了。

　　The tropics contain a larger surface area of land than higher latitudes and some biogeographers regard the differences in diversity as a reflection of this effect.

　　中文：一個(gè)事實(shí)

　　中文：不總是那么明顯

　　修飾三：(when we examine commonly used projections of Earth's curved surface) ，從句

　　中文：當(dāng)我們?cè)谧屑?xì)觀察通常所用的地球曲面投影時(shí)

　　修飾四：(since this tends to exaggerate the areas of land in the higher latitudes) ，從句

　　中文：因?yàn)檫@往往夸大了高緯度的土地面積

　　參考翻譯：

　　熱帶比高緯度包含更大的的土地面積——當(dāng)我們?cè)谧屑?xì)觀察通常所用的地球曲面投影時(shí)，這一事實(shí)并不總是顯而易見的，因?yàn)檫@往往夸大了高緯度的土地面積——并且一些生物地理學(xué)家認(rèn)為多樣性的差異反映了這一影響。
