Since most seagrass systems are depositional environments, they eventually accumulate organic material that leads to the creation of fine-grained sediments with a higher organic content than that of the surrounding unvegetated environment.
結(jié)構(gòu)分析:
復合句。Since 引導原因狀語從句,主句中包含that引導的定語從句。
句子分析:
原因狀語從句Since most seagrass systems are depositional environments中,most seagrass systems 作主語,are depositional environment為系表結(jié)構(gòu)。本部分意思:因為大多數(shù)的海草系統(tǒng)屬于沉積性環(huán)境。
they eventually accumulate organic material… surrounding unvegetated environment為主句。其中,they是主語,accumulate是謂語,organic material是賓語。本部分意思:它們最終會積累有機物質(zhì)。
that引導的定語從句修飾organic material,其中,that作主語,leads to為謂語,the creation是賓語,of fine-grained sediments with a higher organic content為定語修飾賓語。本部分意思:會產(chǎn)生有機物質(zhì)含量更高的細顆粒沉淀物。
介詞短語than that of the surrounding unvegetated environment作定語。其中,that是代詞,指的是organic content,of the surrounding unvegetated environment 定語,修飾that。本部分意思:比起周圍無植被區(qū)的細顆粒狀沉淀物的有機物質(zhì)含量。
參考翻譯:
由于大多數(shù)海草系統(tǒng)屬于沉積性環(huán)境,它們最終會積累有機物質(zhì),進而形成有機物質(zhì)含量高于周圍無植被區(qū)的細顆粒狀沉淀物。
