2017年11月SAT北美考试结束，考完的小伙伴一定想知道正确答案吧，
Questions 1-11 are based on the following passage.
Robonaut 2: A Revolution in Robotics
What if an astronaut could have an 1 extra pair of hands. NASA, in conjunction with private companies, has realized this possibility through the development of humanoid robotic technologies. The latest of its anthropomorphic robots, the Robonaut 2(R2), is capable of replicating human movements with precision.
1
A)NO CHANGE
B)extra pair—of hands!
C)extra pair of hands?
D)extra, pair of hands?
First sent to the International Space Station in 2011, R2 2 mimics the form and function of the human body. The robot’s head houses high-definition and infrared camera eyes that allow operators to see what the robot sees and control its
movements. Its arms and hands are equipped with elastic joints as well as cables that function like human tendons, enabling R2 to use the same instruments astronauts use. Tiny 3 sensors in the robot’s fingertips, analogous to nerve endings, enable the robot to measure and adjust the force it applies, thereby providing an essential safety feature. While R2 initially consisted of a head, torso, and arms mounted on a rolling pedestal, it was equipped with mechanical legs in early 2014,an
innovation that has enhanced the robot’s mobility.

Which choice most effectively sets up the examples provided in the paragraph?
A)NO CHANGE
B)has been given increasingly demanding tasksby engineers on the station.
C)began its long journey of development in 1997,when the first Robonaut was unveiled.
D)was actually intended to be a prototype thatwould be carefully studied on Earth.
3
A)NO CHANGE
B)sensor’s in the robot’s
C)sensors’ in the robots
D)sensors in the robots
R2’s current onboard role is Limited to mundane yet 4 crucially essential maintenance tasks. For example, the job of monitoring air vents requires that a gauge be held in a fixed position for an extended period of time; shifting this task to R2 produces more accurate measurements and frees astronauts to focus on more complex work. 5 Furthermore, by studying R2’s performance of basic tasks, NASA chief robotics engineer Robert Ambrose and his team obtain 6 data. The data they obtain are necessary to their ongoing development of the robot’s software.
4
A) NO CHANGE
B) essentially crucial
C) essential
D) routine
5
At this point, the writer is considering adding the following sentence. In fact, in 2007, NASA signed a Space ActAgreement with a private company in order to guarantee that enough resources would be available for the development of R2. Should the writer make this addition here?
A)Yes, because it contributes valuableinformation about the history of R2’sdevelopment.
B)Yes, because it illustrates the point madeopening paragraph about the participation ofprivate companies.
C)No, because it diverges from the paragraph’sdiscussion of the kinds of work that R2 does.
D)No, because it does not specify the kinds ofresources that were needed in the developmentprocess.
6
Which choice most effectively combines the sentences at the underlined portion?
A)data
B)data —data that are
C)data, the obtaining of which is
D)data; these data are
[1]NASA believes that R2, once fully developed,will have wide-ranging applications. [2] By performing dangerous tasks such as repairs to the exterior of the space station, R2 will keep astronauts safer and eliminate the need for additional
specialized equipment. [3] Scientists even envision R2 as a remote-controlled surgeon. [4] Performing the role of a scout, 7 the surface of Mars might one day be explored by the robot and provide astronauts with maps and soil samples; such data would help astronauts prepare for future exploration. [5] The robot might also perform a caretaking function by maintaining the space station between missions. [6]According to Dr. Zsolt Garami, a medical 8researcher works in conjunction with NASA, the robotic hands of R2 might one day perform intricate operations while human doctors monitor it from thousands of miles away. 9
7
A) NO CHANGE
B) Mars’s surface might one day be explored bythe robot
C) the robot might one day explore the surface ofMars
D) one day, the surface of Mars might be exploredby the robot
8
A)NO CHANGE
B)researcher, which works
C)researcher, and working
D)researcher who works
9
To make this paragraph most logical, sentence 3 should be placed
A)where it is now.
B)after sentence 1.
C)after sentence 5.
D)after sentence 6.
Fusing human dexterity with technological resilience, R2 marks a unique achievement in the development of humanoid robotic technology. As 10 their own capabilities continue to evolve, R2 stands 11 to transform the ways ordinary people back on Earth perform their daily activities.
10
A) NO CHANGE
B) Their
C) its
D) it’s
11 The writer wants to make a reasonable prediction that stays within the context established by the passage. Which choice most effectively accomplish this goal?
A)NO CHANGE
B)to play an even more vital role aboard theInternational Space Station.
C)for the tremendous potential of robotics in justabout any field of human endeavor.
D)tall as an achievement whose scale NASA isunlikely to replicate anytime soon.
