托福閱讀高難度文章長(zhǎng)難句實(shí)例解析：大量物種周期性滅絕假說(shuō)

　　The possibility that mass extinctions may recur periodically has given rise to such hypotheses as that of a companion star with a long-period orbit deflecting other bodies from their normal orbits, making some of them fall to Earth asmeteors and causing widespread devastation upon impact.

　　詞匯講解：

　　recur /r?'k??/ v. 再發(fā)生，復(fù)發(fā)

　　periodically adv.定期地，周期性發(fā)生地

　　hypothesis /ha?'pɑθ?s?s/ n. 假說(shuō)，假設(shè)

　　deflect /d?'fl?kt/ v. (使某物)運(yùn)動(dòng)轉(zhuǎn)向;使某人改變?cè)瓉?lái)的計(jì)劃

　　meteor /'mi?t??/ n. 流星

　　devastation /?dev?'ste??n/ n. 毀壞，荒廢

　　impact /?m'pækt/ n. 撞擊，沖擊;影響

　　such sth as/that...：(像後面提及的)那樣的, 這樣的

　　結(jié)構(gòu)劃分：

　　The possibility (that mass extinctions may recur periodically) has given rise to such hypotheses as that (of a companion star)(with a long-period orbit) (deflecting other bodies from their normal orbits), (making some of them fall to Earth as meteors) and (causing widespread devastation upon impact).

　　深度分析：

　　這個(gè)句子的主干很簡(jiǎn)單：

　　The possibility has given rise to such hypotheses

　　注意這里的such sth as/that...：(像後面提及的)那樣的, 這樣的

　　例如：

　　Such a disaster as her car being stolen had never happened before.

　　Such poets as Keats and Shelley wrote Romantic poetry.

　　修飾一：(that mass extinctions may recur periodically)，從句，解釋possibility

　　中文：大量物種滅絕可能會(huì)周期性發(fā)生

　　修飾二：(of a companion star) ，介詞短語(yǔ)

　　中文：一顆伴星

　　修飾三：(with a long-period orbit) ，介詞短語(yǔ)

　　中文：有長(zhǎng)周期軌道

　　修飾四：(deflecting other bodies from their normal orbits)，非謂語(yǔ)動(dòng)詞

　　中文：使其它天體偏離正常軌道

　　修飾五：(making some of them fall to Earthas meteors)，非謂語(yǔ)動(dòng)詞

　　中文：使一些天體作為流星落入地球

　　修飾六：(causing widespread devastationupon impact)，非謂語(yǔ)動(dòng)詞

　　中文：在撞擊時(shí)造成大范圍破壞

　　參考翻譯：

　　大量物種滅絕可能會(huì)周期性發(fā)生的可能性引起了像這樣一個(gè)假說(shuō)：一顆有長(zhǎng)周期的伴星使其它天體偏離正常軌道，使一些天體作為流星落入地球，并在撞擊時(shí)造成大范圍破壞。
