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 (接轨舱门) on the station.The ports will be used when other people arrive at the ISS in 2017.Also,the two astronauts fixed a thermal (热的) 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 (调整) 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 文章讲述了两个宇航员Kelly 和Lindgren为了维护ISS正常运转在太空工作生活的场景.
解答 DAC
33.D 细节推理题.根据第一段And just like any other home,the ISS requires some housekeeping,in the form of regular work and repairs.就像其他家一样,ISS也需要一些照顾,但是以维修等为主,这都是为了让ISS正常的工作,故选D.
34.A 细节题.根据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长,所以他能做一些更有挑战性的工作,故选A.
35.C 猜测词题.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.句意为,这种调整能应付宇航员身体里任何的变化,所以此处address是动词,对付、处理的意思,故选C.
点评 考察学生的细节理解和推理判断能力,做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确的选择.在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.
