1. The trouble is that part of the recent acceleration is due to the usual rebound that occurs at this point in a business cycle, and so is not conclusive evidence of a revival in the underlying trend.

【譯文】問題在于，近期生產(chǎn)力快速增長的部分原因是經(jīng)濟(jì)周期的正常反彈，并不足以說明潛在的趨勢已經(jīng)預(yù)示經(jīng)濟(jì)復(fù)蘇。

【析句】句子的表語較長，作為表語的從句由兩個分句組成，但是主語都是part of the recent acceleration。必須清楚is not conclusive evidence of a revival in the underlying trend的主語是part of the recent acceleration。

【講詞】 acceleration意為"加速"，在句中是"經(jīng)濟(jì)加速"的意思。This bus has good acceleration.（這輛公共汽車的加速性能很好。）revival意為"復(fù)興；復(fù)蘇"，在句中是"經(jīng)濟(jì)復(fù)蘇"的意思。conclusive意為"確實(shí)的,比較后的,決定性的"。conclusive evidence（確鑿的證據(jù)）。

2. New ways of organizing the workplace-all that reengineering and downsizing-are only one contribution to the overall productivity of an economy, which is driven by many other factors such as joint investment in equipment and machinery, new technology, and investment in education and training.

【譯文】企業(yè)重組的新方法--所有那些重新設(shè)計和縮小規(guī)模的做法--只是對一個經(jīng)濟(jì)的整體生產(chǎn)力做出了一方面的貢獻(xiàn)，而這種經(jīng)濟(jì)的發(fā)展還受到許多其他因素的驅(qū)使，如設(shè)備、機(jī)械上的聯(lián)合投資，新技術(shù)，以及教育和培訓(xùn)上的投資。

【析句】句子的主干是New ways of organizing the workplace... are only one  contribution to the overall productivity of an economy。破折號中間的成分是插入語，是主語New ways of organizing the workplace的同位語。the overall productivity of an economy后面跟了一個which引導(dǎo)的定語從句，其中such as joint investment in equipment and machinery...and training是賓語many other factors的同位語。

【講詞】 contribute意為"貢獻(xiàn)；起作用；出力"。Drinking contributed to his ruin.（酗酒促使他毀滅。）She seldom contributes to the discussion.（她在討論中很少發(fā)言。）注意contribute后面通常跟介詞to。
