在英語四級(jí)考試中，聽力理解部分無疑是考生們需要重點(diǎn)關(guān)注的環(huán)節(jié)。小編為大家整理了“2024年12月英語四級(jí)真題聽力第二套”Passage 1的內(nèi)容，希望為大家備考帶來幫助！
英文原文
Passage 1
文章1
Liftoff is usually the most environmentally harmful stage of any space mission, with vast quantities of fuel burnt up in a matter of minutes. For instance, SpaceX's Falcon 9 gets through 112 tons of refined fuel, emitting about 336 tons of CO2. This is the equivalent produced by your average car driving almost 70 times around the world. As well as greenhouse gases, rocket engines emit particles that destroy ozone.
發(fā)射通常是任何太空任務(wù)中對(duì)環(huán)境危害最大的階段，在短短幾分鐘內(nèi)就會(huì)燃燒掉大量燃料。例如，SpaceX的獵鷹9號(hào)消耗112噸精煉燃料，排放約336噸二氧化碳。這相當(dāng)于一輛普通汽車?yán)@地球行駛近70圈所產(chǎn)生的排放量。除了溫室氣體，火箭發(fā)動(dòng)機(jī)還會(huì)排放破壞臭氧層的顆粒。
These issues are growing more pressing with the emergence of commercial space flight. There were 114 space launches in 2020, but there may be up to 1,000 per year in future.
隨著商業(yè)太空飛行的出現(xiàn)，這些問題變得愈發(fā)緊迫。2020年有114次太空發(fā)射，但未來每年可能會(huì)有多達(dá)1000次。
Sustainable fuels are the top priority to enable greener space travel. Current spacecraft use a variety of fuels, but most are based on fossil fuels. One potentially greener option is liquid hydrogen and oxygen. Hydrogen can be obtained sustainably by using solar power to break water down into oxygen and hydrogen.
實(shí)現(xiàn)更環(huán)保的太空旅行，可持續(xù)燃料是首要任務(wù)。目前的航天器使用多種燃料，但大多數(shù)基于化石燃料。一個(gè)可能更環(huán)保的選擇是液態(tài)氫和氧。通過使用太陽能將水分解成氧和氫，可以可持續(xù)地獲取氫。
Reusable rockets can cut down on some of the waste associated with spaceflight. Traditionally, boosters, fuel tanks and other components are treated as expendable. But guiding them back to earth in a controlled manner opens new possibilities.Most components from the Falcon 9 can be reused up to 100 times.
可重復(fù)使用的火箭可以減少與太空飛行相關(guān)的一些浪費(fèi)。傳統(tǒng)上，助推器、燃料箱和其他部件被視為消耗品。但以可控的方式引導(dǎo)它們返回地球，開辟了新的可能性。獵鷹9號(hào)的大多數(shù)部件可以重復(fù)使用多達(dá)100次。
Truly environmentally friendly space travel is still some way off, but we already have many of the technologies needed to start limiting its impact on our planet.
真正環(huán)保的太空旅行仍有一段距離，但我們已經(jīng)擁有許多限制其對(duì)地球影響所需的技術(shù)。
Questions 16 to 18 are based on the passage you have just heard.
問題16至18基于你剛剛聽到的文章。
Question 16: What do we learn from the passage about the liftoff of spacecraft?
問題16：我們從文章中了解到關(guān)于航天器發(fā)射的什么信息？
Question 17: What happens traditionally to boosters, fuel tanks and other components in space flight?
問題17：在太空飛行中，助推器、燃料箱和其他部件傳統(tǒng)上會(huì)發(fā)生什么？
Question 18: What does the passage say we already have regarding space flight?
問題18：文章提到我們?cè)谔诊w行方面已經(jīng)擁有了什么？
