托福長難句分析：深海底部環(huán)境
Totally without light and subjected to intense pressures hundreds of times greater than at the Earth’s surface，the deep—ocean bottom is a hostile environment to humans，in some ways as forbidding and remote as the void of outer space.
(定語后置in some ways…)
由于完全沒有光，而且承受著比在地球表面大數(shù)百倍的極大壓力，深海底部對人類而言是一個充滿敵意的環(huán)境，在某些方面就像外層空間一樣險惡和遙遠。
分句1：Totally without light and subjected to intense pressures
分句2：hundreds of times greater than at the Earth’s surface
分句3：the deep—ocean bottom is a hostile environment to humans
分句4：in some ways as forbidding and remote as the void of outer space
分句2修飾分句1結(jié)尾的短語intense pressures，
分句1是分句3的原因狀語
分句3是整個長句子的主句
分句4是分句3的后置定語，修飾分句3的a hostile environment to humans
整個句子結(jié)構(gòu)是：原因狀語+主句+后置定語
這是主句前后分別有狀語和定語的修飾成分，但是本句其實不是復(fù)合句。句子的核心意思是深海對于人類而言是一個充滿敵意的環(huán)境。
托福長難句分析：核心業(yè)務(wù)外包
Some great manufacturers and great service companies may have become too lean in their relentless drive to reduce costs, outsourcing not just their non-core activities but essential ones too.
【結(jié)構(gòu)分析】本句不難，逗號前為主句Some great manufacturers and great service companies may have become too lean in their relentless drive to reduce costs,使用了too…to…結(jié)構(gòu)，句末的現(xiàn)在分詞結(jié)構(gòu)outsourcing not just their non-core activities but essential ones too作伴隨狀語，進一步補充說明reduce costs的具體內(nèi)容。
【參考譯文】有些大的制造商和服務(wù)供應(yīng)商熱衷于降低成本，不僅把非核心業(yè)務(wù)外包，而且連核心業(yè)務(wù)也不放過。
