復(fù)雜的分割結(jié)構(gòu)（插入語）的理解 例217

例217　According to their latest paper published in Nature, the biomass of large predators (animals that kill and eat other animals) in a new fishery is reduced on average by 80% within 15 years of the start of exploitation.

【結(jié)構(gòu)分析】句子開頭是個(gè)介詞短語According to their latest paper published in Nature做狀語，句子的主干的主語是the biomass of large predators，后面是個(gè)括號(hào) (animals that kill and eat other animals) 是個(gè)插入語，表示解釋生詞，后面是個(gè)介詞短in a new fishery做定語，后面是動(dòng)詞is reduced，后面是介詞短語on average做狀語，后面是介詞短語by 80％做狀語，后面是介詞短語within 15 years of the start of exploitation做狀語。

【亮點(diǎn)回放】此句話的亮點(diǎn)在于三個(gè)連環(huán)介詞短語做狀語，讓句子顯得很生動(dòng)，介詞短語是重要的手段表達(dá)句子的程度，時(shí)間，地點(diǎn)和范圍。
