美國航空航天局（ NASA ）首次推出新巨型月球火箭。該飛行器被稱作 “太空發(fā)射系統(tǒng)（ Space Launch System, SLS ）”，它被帶到佛羅里達州肯尼迪航天中心的  39B  號發(fā)射臺上進行模擬倒計時演習(xí)。

They call it the Space Launch System, or SLS, and it's a colossus. More powerful than the Apollo-era rockets, this new vehicle is designed to be able to send so much equipment and cargo to the Moon, the men and women will be able to stay there for extended periods.

它被稱為 “太空發(fā)射系統(tǒng)”，簡稱 “SLS”，是個龐然大物。這種新型運載工具比阿波羅時代的火箭更強大，設(shè)計它是為了向月球運送大量設(shè)備和物資，使得人類能在那里停留更長時間。

Nasa dispatched a mammoth tractor to ferry the SLS from its assembly building to the launch pad at the Kennedy Space Center. Once fully installed, engineers will conduct a dummy countdown to check all the systems are working.

美國航空航天局派出了一輛巨型拖車，將 “太空發(fā)射系統(tǒng)” 火箭從其裝配大樓運送到肯尼迪航天中心的發(fā)射臺。一旦安裝完畢，工程師將進行模擬倒計時，以檢查所有系統(tǒng)是否運轉(zhuǎn)正常。

If no problems are found, the rocket will launch an uncrewed capsule to loop around the Moon in the coming months. And if that goes well, astronauts will then start flying on a succession of SLS vehicles.

如果沒有發(fā)現(xiàn)問題，火箭將在未來幾個月內(nèi)發(fā)射一個無人太空艙，圍繞月球飛行。如果進展順利，宇航員們將開始執(zhí)行一系列 “太空發(fā)射系統(tǒng)” 火箭的飛行任務(wù)。

閱讀理解：請在讀完上文后，回答下列問題。

1. What will this new rocket allow people to do?

2. How was this new rocket moved to its launch pad?

3. True or false? The rocket will be launched by a dummy.

4. Where will the rocket go on its first flight?

答案  

1. What will this new rocket allow people to do?
It will allow men and women to stay on the Moon for extended periods of time.

2. How was this new rocket moved to its launch pad?
A huge (mammoth) tractor was used to move the SLS from its assembly building to the launch pad.

3. True or false? The rocket will be launched by a dummy.
False. A dummy countdown is a mock countdown to check all the systems are working. Here, ‘dummy’ doesn’t mean a model of a human.

4. Where will the rocket go on its first flight?
The rocket will launch an uncrewed capsule to loop around the Moon.
