Passage 2
Questions 6 to 10 are based on the following passage.
On July 20, 1969, Neil Armstrong became the first person to walk on the moon. The spacesuit Armstrong wore on his mission has come to symbolize courage and human achievement. In 1971, the Smithsonians National Air and Space Museum (NASM)acquired Armstrong's suit. It stood proudly on display fbr visitors to admire, until there were changes in the suits appearance. "Over time, the suit started to show signs of deterioration (变坏)Lisa Young says. She works at NASM and her job is to preserve historical and cultural treasures.
Plastics are tricky to preserve.They tend to degrade (降解)over time. Neoprene is one type of plastic in Armstrong's suit. The material can turn brittle and break into tiny pieces. (77)This would ruin the spacesuit, NASM, seeking ways to preserve this historical treasure, removed it from display in 2006.
Yet history can still be saved. Sunlight, water, humidity, and dust can cause plastics to degrade. Scientists have found that storing plastics in cooler temperatures, with lower humidity levels, can slow degradation.Young says Armstrong's suit is currently in storage at a temperature of 63°F and a lower relative humidity of 30%. These conditions will be maintained when Armstrong's suit returns to a museum display case in time fbr this year's 50th anniversary (周年纪念 H ) of the moon landing.
Plastic degradation affects art, too. Artist Claes Oldenburg created False Food Selection in 1906. (78) It consists of plastic food displayed in a wooden box. The plastic food used to look real. Now , some of it has flattened and yellowed. The artwork's wooden box produces an acidic gas that eats away at the plastic, which speeds up the degradation process. But Young is motivated to preserve this artwork and others like it. "Plastics are a part of our history,, she says, "it's important to preserve them so that foture generations can understand the journey we've taken.
6.Which of the following is the best title fbr the passage?
Landing on the Moon
Preserving Plastics
Neil Armstrong's Spacesuit
Application of Plastics
6. 答案】B
【定位】全文
【详解】主旨大意题。题干问“以下哪项是最适合本文的标题？”根据全文大意，文章主要讲解塑料的降 解和保护，A“登陆月球”，C“尼尔•阿姆斯特朗的宇航服”，D“塑料的应用”，都不合适。故选B。
7.The word brittle in Paragraph 2 probably means .
well established
heavily loaded
easily upset
easily broken
7. 【答案】D
【定位】第二段第四句"The material can turn brittle and break into tiny Pieces.,
【详解】词汇题。题干问“brittle”的含义，首先找它所在的句子“The material can turn brittle and break into tmy Pieces ”，这句话指塑料发生降解之后会变脆然后碎裂成小碎片。比较选项，A“很好地建立的”，B“很重 地承载着”，C“很容易打翻地”，D“很容易打碎的”，D比较合适。故选D。
8.In 2006, NASM removed Armstrong's spacesuit from display to .
put it on sale
return it to Amistrong
give it to another museum
look fbr ways to preserve it
8. 【答案】D
【定位】 第二段最后—句"...ASM, seeking ways to preserve this historical treasure, removed it from display in 2006 ”。
【详解】细节题。题干间“史密森尼国家航空航天博物馆将字航服从展馆中转移的目的？ ”由定位句可知， 目的在于寻求保存它的方法。故选D。
9.In Claes Oldenburg's False Food Selection, the wooden box the plastic degradation.
slows down
leads to
accelerates
doesn't play any role in
9.【答案】C
【定位】最后一段第六句话"The artwork's wooden box produces an acidic gas that eats away at the plastic, which speeds up the degradation process.
【详解】细节题。题干问“在克拉斯-奥尔登堡的虚假食物选择中，木箱对塑料的降解有什么作用？''由 定位句可知，木箱会释放一种酸性气体，该气体可以加速塑料降解。该句的speed up和accelerate同义，故 选C。
10.According to the passage, which of the following statements is NOT TRUE?
Sunlight, water and dust contribute to plastic degradation.
Armstrong's spacesuit is currently on public display at NASM.
NASM acquired Armstrong's spacesuit in 1971.
Claes Oldenburg is an artist.
10. 【答案】B
【定位】 第二段最后—句"...NASM, seeking ways to preserve this historical treasure, removed it from display in 2006.”。
【详解】细节题。注意题干问的是表述“不正确”的一项。由第三段第一句可知，阳光、水、湿度和灰尘能 够降解塑料，故A正确。由第一段第三可知，NASM在1971年收购了阿姆斯特朗的宇航服，故C正确。由 第四段可知，D正确。由第二段后最后一句可知，2006年宇航服已经从博物馆展厅中移出以寻求更好地保 存方法。B选项说宇航服还在展厅中，不正确。故选B。
