19考研英語：屠屠長難句（五十三）

1每日一句長難句
Car drivers can buy electro-petrol hybrids but aircraft are, for now, stuck with kerosene, because its energy-density makes it the only practical fuel to carry around in the air.

2【結構分析】
以連詞but爲切入點，將句子分割成兩個並列分句。第二個並列分句中for no是時間狀語，aircraft are stuck with kerosene是主句, because its energy-density makes it the only practical fuel to carry around in the air是原因狀語從句，其中使用了make it sth.(使它成爲……)結構。

3【詞彙】
hybrid 混合物

be stuck 停止不動---此處爲“依舊使用”

density 密度

fuel 燃料

4【參考譯文】
小汽車司機可以購買電力汽油混合動力的汽車，但是飛機到目前只能用煤油，因爲它的能量密度使其成爲唯一可以在空中攜帶的燃料。

5【明日長難句】
The Aswan Dam, for example, stopped the Nile flooding but deprived Egypt of the fertile silt that floods left——all in return for a giant reservoir of disease which is now so full of silt that it barely generates electricity.
