14.Astronaut Scott Kelly has been living on the International Space Station (ISS) since March 28,2015.And just like any other home,the ISS requires some housekeeping,in the form of regular work and repairs.
That is why Kelly and his partner Kjell Lindgren performed activities,outside the station on Wednesday.The operation began at 8:03AM and lasted for more than seven hours.It was the first spacewalk for both men.
The ISS has been in continual use for 15years,and has hosted over 200people,including astronauts and private tourists.During their activities,Kelly and Lindgren did basic electrical work,such as attaching new wires that will provide power to docking ports (接軌艙門) on the station.The ports will be used when other people arrive at the ISS in 2017.Also,the two astronauts fixed a thermal (熱的) cover on a key scientific instrument on the station to protect it from the severe temperatures of space.
As the more senior astronaut,Kelly led the spacewalk.However,Lindgren dealt with some of the more challenging parts of the job as he has longer arms than Kelly.
During a spacewalk,the simplest work becomes a difficult task.Kelly and Lindgren spent months training and practicing for the operation.The preparation began in NASA's Neutral Buoyancy Lab (NBL).Here astronauts are made to work in an environment similar to the one outside the space station~
Even getting the space suits ready can take days.While each suit is built to fit perfectly on the astronaut who will wear it,adjustments (調整) need to be made fight up to the time when the spacewalk begins.The adjustments address any changes in the astronauts'bodies that have occurred as a result of being in a gravity-free environment.
33.Kelly and Lindgren took the spacewalk just toD
A.clean up the ISS
B.carry out a scientific experiment
C.test their new space suits
D.keep the ISS in good condition
34.Why did Kjell Lindgren do more challenging work than Kelly during the spacewalk?A
A.He had physical advantages.
B.He was the leader of the group.
C.His space suit was more comfortable.
D.His experience of spacewalking was longer.
35.The underlined word"address"in the last paragraph meansC
A.focus on B.record
C.deal with D.direct.
分析 文章講述了兩個宇航員Kelly 和Lindgren為了維護ISS正常運轉在太空工作生活的場景.
解答 DAC
33.D 細節(jié)推理題.根據第一段And just like any other home,the ISS requires some housekeeping,in the form of regular work and repairs.就像其他家一樣,ISS也需要一些照顧,但是以維修等為主,這都是為了讓ISS正常的工作,故選D.
34.A 細節(jié)題.根據Lindgren dealt with some of the more challenging parts of the job as he has longer arms than Kelly.得知,Lindgren由于胳膊比Kelly長,所以他能做一些更有挑戰(zhàn)性的工作,故選A.
35.C 猜測詞題.在最后一段The adjustments address any changes in the astronauts'bodies that have occurred as a result of being in a gravity-free environment.句意為,這種調整能應付宇航員身體里任何的變化,所以此處address是動詞,對付、處理的意思,故選C.
