托福閱讀長難句100句：消失的化石

　　At one time, the animals present in these fossil beds were assigned to various modern animal groups, but most paleontologists now agree that all Tommotian fossils represent unique body forms that arose in the early Cambrian period and disappeared before the end of the period, leaving no descendants in modern animal groups. (52, TPO5)

　　paleontologist /?pe?l??n?t?l?d ??st/ n. 古生物學(xué)家

　　descendant /d?'send(?)nt/ n. 子孫，后代

　　我是分界線，大家先自己分析哦。

　　At one time, the animals (present in these fossil beds) were assigned to various modern animal groups, but most paleontologists now agree that all Tommotian fossils represent unique body forms (that arose in the early Cambrian period and disappeared before the end of the period), (leaving no descendants in modern animal groups.)

　　分析：

　　修飾一：(present in these fossil beds)，形容詞短語，修飾animals，注意是放在后面哦

　　中文：存在于這些化石床中

　　修飾二：(that arose in the early Cambrian period and disappeared before the end of the period)，從句，修飾body forms

　　中文：出現(xiàn)在Cambrian時期早期，并在這個時期末期前消失

　　修飾三：(leaving no descendants in modern animal groups.)，非謂語動詞修飾前面的主干

　　中文：在現(xiàn)代動物群組中沒有留下后代

　　主干：most paleontologists now agree that，that后面整個賓語從句，從all到groups

　　參考翻譯：

　　曾經(jīng)，存在于這些化石床中的動物被分配到各種現(xiàn)代動物群組中，但現(xiàn)在大多數(shù)古生物學(xué)家都同意：所有Tommotian的化石代表了出現(xiàn)在Cambrian時期早期并在這個時期末期前消失獨特的化石形式，在現(xiàn)代動物群組中沒有留下后代。

　　這個句子的主要修飾成分就是從句、非謂語動詞，大家務(wù)必想清楚，每一個修飾成分修飾的是什么，才能看清楚這個句子的結(jié)構(gòu)。
