　　賓語從句的主干：the water should pass across the blades as smoothly as possible and fall away with minimum speed

　　中文：水應(yīng)該從葉輪上盡可能光滑地流過，并以最小的速度流走

　　修飾一：(ranging from about 1 horsepower to perhaps 60)，非謂語動詞

　　中文：輸出功率范圍是從1馬力到最大水輪可能輸出的60馬力

　　修飾二：(for the largest wheels)，介詞短語

　　中文：對于最大水輪

　　修飾三：(for maximum efficiency)，介詞短語

　　中文：為了達到最高效率

　　修飾四：(having given up almost all of its kinetic energy)，非謂語動詞

　　中文：釋放水的幾乎所有動能

　　托福閱讀長難句100句參考翻譯：

　　它們(調(diào)查)顯示輸出功率范圍是從1馬力到最大水輪可能輸出的60馬力;它們也確定了要達到最高效率，水應(yīng)該從葉輪上盡可能光滑地流過，并以最小的速度流走，釋放水的幾乎所有動能。

　　這個句子的主要修飾成分就是介詞短語、非謂語動詞、從句，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)。
