這句話是個并列句，第一個句子"Without the upper stage, and minus most of the fuel it had at liftoff, it weighed only a fraction of its launch weight"，"Without the upper stage, and minus most of the fuel"可看成是原因狀語，注意"minus"在這也是介詞詞性，句子的主語"it"，謂語"weighed"，賓語"a fraction of its launch weight"，"so"作為連詞引導(dǎo)一個句子表達(dá)一個結(jié)果，主語"it"，謂語"didn’t take"，賓語"as much fuel"，"to slow down"可看成目的狀語，"and"起到并列連接目的狀語中不定式動作的作用，也就是"slow down"和"reverse (course)"；當(dāng)然，"slow down"后面就沒有賓語了 ，而"reverse"后面帶賓語，"to head back to Cape Canaveral"可算是"to reverse course"的目的狀語；注意"to head back to Cape Canaveral"第一個"to"引導(dǎo)動詞不定式，第二個"to"是介詞，后接介詞賓語（名詞性成份）"Cape Canaveral"。

 

 

由于一級火箭已與二級火箭脫離, 并已消耗其升空時攜帶的大部分燃料, 其重量僅為發(fā)射時的一小部分,因此減緩速度、調(diào)頭返回卡納維拉爾角并不需要太多燃料。
