第二部分 话题阅读训练
（A）阅读理解
Robotic surgery is one thing, but sending a robot inside the body to carry out an operation quite another, which has
long been a goal of some researchers to produce tiny robotic devices being capable of traveling through the body to deliver
drugs or to make repairs without the need for a single cut, the possibility of which has just got a bit closer.
However, unlike the plot of one film—which featured a microscopic crew and submarine traveling through a
scientist’s bloodstream — this device could not be inserted into blood vessels（管） because it is too big. While other types
of miniature swallowable robots have been developed in the past, their role has mostly been limited to capturing images
inside the body. In a presentation this week to the International Conference, Daniela Rus and Shuhei Miyashita of the
Massachusetts Institute of Technology described a robot they have developed that can be swallowed and used to collect
dangerous objects accidentally taken in.
To test their latest version, Dr Rus and Dr Miyashita designed a robot as a battery hunter, which might seem to be an
odd task, but more than 3,500 people in America alone, most of them children, swallow the tiny button cells used in small
electronic devices by accident every year. To start with, the researchers created an artificial esophagus（食道） and stomach
made out of silicone(硅胶). It was closely modeled on that found in a pig and filled with medical liquid; the robot itself is
made from several layers of different materials, including pig intestine（肠） , and contains a little magnet. This is folded up
and encased in a 10mm×27mm capsule of ice. Once this reaches the stomach the ice melts and the robot unfolds which is
moved and guided with the use of a magnetic field outside the body. In their tests, the robot was able to touch a button
battery and draw it with its own magnet, and during dragging it along, the robot could then be directed towards the
intestines where it would eventually be gotten rid of through the anus(肛门). After it, the researchers sent in another robot
loaded with medication to deliver it to the site of the battery burn to speed up healing.
The artificial stomach being transparent on one side, the researchers were able to see the batteries and visually control the robots. If not, that will require help with the help from imaging system, which will be a bit more of a challenge, but Dr
Rus and Dr Miyashita are determined to succeed.
4 ．According to the passage, the robot operation will probably be able to .
A ．travel through a scientist’s bloodstream
B ．enter the body to deliver drugs or make repairs
C ．photograph the body to convey to the doctor
D ．operate on a person outside the body completely
5 ．We learn from Paragraph 3 that .
A ．the researchers did the experiment on a chosen animal
B ．the actual size of the robot may be larger than the capsule of ice
C ．digesting the swallowed batteries is difficult for children
D ．the robot took necessary drugs besides a little magnet
6 ．What may the experiment mean to the medical world
A ．Fewer children will swallow the button cells.
B ．A robot will be invented travelling blood vessels.
C ．The surgeries will cost patients much money.
D ．Patients will suffer less for some surgeries.
7 ．Which can be the most suitable title for the passage
A ．The Fantastic Robotic Voyage B ．The Exploration of Robot Technology
C ．Tiny Robot, Significant Role D ．An Experiment on Robot
（B）完形填空
Early on Saturday morning,parents and viewers walked in a line into the gym at the Einste Academy, a school in
Illinois in the US. After the coach 21 his opening speech everyone 22 for the US's national song. After the
song, judges dressed in black and white shirt took up their 23 outside the playing field, ready for the games to begin.
While this sounds like the typical setting of a US sporting event, this one had a high-tech twist, was a competitive
robotics 24 —a game that turns the subjects of science, technology, engineerin and mathematics into a competitive
sport.
25 by coaches, teams of students in grade 7 through 12 who designed, built and programmo their own robots
competed against other robotics teams in the West Suburban League North Division the FIRST Tech Challenge (FTC).
“Most students experience multiple-choice questions.” said Jonathan Weiland, who works f FIRST Tech Challenge in
Illinois. “In FTC, there are hundreds of solutions to a problem and they see which solution 26 the best.”
“Founded by a not-for-profit organization, FIRST (For Inspiration and Recognition of Science ai Technology) events are modeled after traditional sports like basketball to generate 27 in robotic,” Weiland said. FIRST Tech Challenge is
one of four FIRST programs.
During a FIRST Tech Challenge, Robotics teams either 28 a robotics kit(配套组件), adjusting and upgrading
their design, or custom build(专门制作) a robot using 29 materials, recording the progress in engineering notebooks.
The robotics teams compete in games within a league, getting points throughout the season 30 a national and even global competitions. There are 35 teams in the West Surburban Leagn North Division and only eight will go to the
state, Weiland said. Teams earn awards based on the robot’s 31 ,design and other accomplishments.
“Judges 32 pair two robotics teams to form a group that competes against two other teams. With multiple games
played by all teams at each meet, a competitor in one game might be a 33 in the next,” Weiland said. Students are
taught to help each other at all times and to 34 the other team, he said.
“One of the best things you can do with your 35 is to share something with someone else,” student said. “It's fun
being on the journey with them.”
