Good news! Tiny robots designed by University of Nebraska researchers may 50 doctors on Earth to help perform surgery on patients in space.
The tiny, wheeled robots, which are about 3 inches tall and as wide a lipstick case, can be slipped into small incisions ( 切口 ) and computer-controlled by surgeons in different 51 . Some robots are equipped with 52 and lights and can send images back to surgeons and others have surgical tools attached that can be controlled 53 .
“ We think this is going to 54 open surgery.” Dr. Dmitry Oleynikov said at a news conference. Oleynikov is a 55 in computer-assisted surgery at the University of Nebraska Medical Center in Omaha.
Officials hope that NASA will teach 56 to use the robots soon enough 57
surgeries could one day be performed in space.
The camera-carrying robots can provide 58 of affected areas and the ones with surgical tools will be able to operate inside the body in ways surgeons’ hands can’t. The views from the camera-carrying robots are 59 than the naked eye, because they 60 back color images that are magnified. Because several robots can be inserted through one incision, they could reduce the amount and 61 of cuts needed for surgery, which would decrease recovery time. This is particularly 62 to those patients who have been weakened by long illness.
Eventually, Oleynikov said, “ The tiny robots may enable surgeons to work without ever __63__their hands in patients’ bodies. That is the 64 . It is getting easier and easier. We can do even more with these devices.”

查看习题详情和答案>>road accidents to minimum is a must. So, automakers are focused on safety systems more than ever
before.
Given the emphasis on improving safety, it's possible that well-known phrases such as "live fast and
die young" may lose their meaning as innovative (创新的) new devices are built into cars and trucks
and other things that go.
Many of the new safety systems that are being added to high-end vehicles are computer-assisted
technologies that transfer some of the vehicle's operations to the vehicle itself, rather than relying only
on the driver's decision-making skills.
For example, predictive brake assist is an in-vehicle feature that prepares the vehicle for braking
when its built-in sensors detect a potential object ahead. The predictive brake assist basically places
the vehicle's braking system on alert, which helps the system to slow down the car in as little time and
as short a distance as possible.
Other in-vehicle sensors will detect moving and still objects and will even distinguish the objects
based on simple patterns, such as other vehicles vs. a person.
What's more, built-in "active systems", i.e., predictive precollision (可预测碰撞) systems, will provide
drivers with advance detection of potential contact between vehicles. These systems compute the
relative movement of the objects and detect possible dangerous intersections (交点).
What technological developments have enabled innovations like predictive precollision systems?
Essentially, these so-called active systems are the result of vehicle-to-vehicle and vehicle-to-infrastructure
communications.
These communication links allow highways to provide a vehicle's owners with services such as renting
a movie during the trip, as well as reduce reaction delays when medical care is needed due to a crash.
Despite these new technologies, drivers cannot take safety for granted.
Until all vehicles are fully automated, it is the drivers themselves who are responsible for operating
their vehicles and obeying traffic laws designed to keep roadways secure. So, keep your eyes on the
road and your hands on the steering wheel (方向盘).
B. compute the relative movement of the contacting vehicles
C. brake the car automatically in as little time as possible
D. detect potential contacts between vehicles in advance
B. Automakers pay more attention to safety system than before.
C. New advanced technology makes the vehicle operation rely only on the vehicle itself.
D. Drivers are still expected to drive carefully despite the built-in advanced safety system.
B. force people to obey traffic laws
C. see a wide use in the future
D. ensure the quality of medical care
B. New systems, safer driving
C. New technology, relaxed drivers
D. High-end vehicles, big innovation
