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 scientists 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 he 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 bum 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.
1.According to the passage, the robot operation will probably be able to ________.
A. travel through a scientist’s bloodstream
B. photograph the body to convey to the doctor
C. enter the body to deliver drugs or make repairs
D. operate on a person outside the body completely

A. the researchers did the experiment on a chosen animal
B. one robot took necessary drugs besides a little magnet
C. digesting the swallowed batteries is difficult for children
D. the actual size of the robot may he larger than the capsule of ice
3.What may the experiment mean to the medical world?
A. The surgeries will cost patients much money.
B. Patients will suffer less for sonic surgeries.
C. Fewer children will swallow the button cells.
D. A robot will be invented travelling blood vessels.

Robotic Puppy
Roll over,sit and fetch aren’t commands normally given to a robot,but the smart toy company WowWee has developed a new way of owning a puppy.
CHIP (Canine Home Intelligent Pet) is a robotic dog with blue LED eyes and pointy ears and can sit,shake,dance and make all types of dog noises.It also has tracking capabilities to help locate its owner.“The beauty about CHIP is that it has its own thing going on,” said Sufer,CTO at WowWee.“It has its own life and own kind of intelligence.Even if you’re not around,it’s always doing something.”
CHIP uses wheels to get around and is loaded with sensors(传感器) that give it a 360-degree view to find its ball.The pup is Bluetooth enabled,which connects to a wristband worn by its owner.The wristband,similar to a watch,displays icons(图标)for different commands such as a thumb-up,which allows you to give your pup a digital belly ruB. With its owner wearing a smart wristband,it can even follow him around the room.
“We worked on CHIP for about five to six months,” Davin Sufer,told dailymail.com,“We typically come up with a concept,model and product and get it on shelves within a year.” The company plans to start shipping units by next fall,which will allow them to load up the robotic dog with sensors and add many more animated responses per-owner interactivity.
The high-tech toy company made its debut(处女作)in 2004 by releasing the 1.5 foot RoboSapien,which sold millions of units.MiP,which hit shelves last year,is a seven inch tall robot covered in white with black accents.Users can direct it,change its emotions and make it dance to any song on your iPad. It’s loud,fast and active.
About 15 years ago,a company called ToyQuest developed the first ever electronic robotic dog---Tekno,the Robotic Puppy.The company sold over seven million units in the first season and 40 million more during its original four years of production.Tekno was built with over 160 emotions and instructions,but most importantly offered consumers a quick look into the future.

Getting stitched(缝合) up by Dr. Robot may one day be reality. Scientists have created a robotic system which did just that in living animals without a real doctor pulling the strings. Much like engineers are designing self-driving cars, the medical research is part of a move toward autonomous surgical robots, removing the surgeon’s hands from certain tasks that a machine might perform all by itself.
Doctors wouldn’t leave the bedside they’re supposed to watch. Plus they’d handle the rest of the surgery. In small tests using pigs, the robotic arm performed at least as well, and in some cases a bit better, as some competing surgeons in stitching together intestinal(肠的) tissue. “The purpose wasn’t to replace surgeons, ”said Dr. Kim who led the project. “If you have all intelligent tool that works with a surgeon, can it improve the outcome? That’s what we have done.”
If you’ve heard about machines like the popular Da Vinci system, you might think robots already are operating. Not really. Today many hospitals offer robot-assisted surgery where surgeons use the machinery as tools that they control by hand to operate through tiny openings in the body. But robot-assisted surgery has been controversial, as some studies have shown it can bring higher costs without better outcomes.
Kim’s team at Children’s Sheikh Zayed Institute invented the new STAR system—it stands for Smart Tissue Autonomous Robot—works sort of like a programmable sewing machine. They added sensors to help guide each stitch and tell how tightly to pull. But the approach wasn’t perfect. In the living animals, the robot took much longer and made a few stitching mistakes while the surgeon sewing by hand made none. Kim said the robot can be sped up. He hopes to begin human studies in two or three years.
1.What’s the best title for the text?
A. A new robotic system
B. A new-style way of stitching
C. The newly-designed driverless vehicles
D. Robot surgeons one step closer to reality
2.What will surgeons do when Dr. Robot is used in surgery?
A. They can help pull the strings. B. They rest at the bedside.
C. They join in when necessary. D. They perform another surgery.
3.Some people are against using robots in surgery probably because_________.
A. they can be out of control B. they will take shorter time
C. they may be expensive to use D. they are likely to cause great pain
4.What can we infer from the text?
A. Dr. Robot can take the place of surgeons.
B. Dr. Robot will be improved.
C. Dr. Robot has been tested with human trials.
D. Dr. Robot can free doctors’ hands in the operation.

After the surgery, Sun suffered intense pain, but insisted that he didn‟t need any medication. One evening, he found Law, his wife, crying on the balcony of their apartment in a rare outburst of frustration. “If you won‟t help yourself, no one else can,” she said.
Sun started a list “How to Help Myself”, and on it he wrote, “Keep communicating with the doctors, even if they are darker thoughts.” On Oct. 20th, a few days before his 33 birthday, Sun wrote in a Facebook post, “It‟s been hard to get along with having aggressive and incurable Grade 4 brain cancer; it‟s been hard not to get angry and sad about it; it‟s been frustrating that every pathology(病理)test after my surgery came back with the worst possible result; and it‟s been hard to accept that modern medicine isn‟t able to fix me.” At the same time, he wrote, “Every day I wake up not-dead is a gift.”
Sun and Law had other lists, detailing the things that they hoped to accomplish in life, which included a trip to Wimbledon; climbing Mt. Snowdon in Wales; and a range of musical aspirations(愿望)----from learning the Bach sonatas(奏鸣曲)and partitas(变奏曲)to performing the first violin part in a concert. Sun started working on Bach‟s six sonatas and partitas for unaccompanied violin, the most difficult parts, which George Enescu, a world-famous violinist, once described as the Himalayas for violinists. Sun practiced every day, even if he could manage only fifteen minutes between medical treatments. As he mastered each piece, he posted his performances on Facebook. He finished on November 12th, then turned to the even more difficult Paganini caprices(随想曲), which he had often listened to in a recording by Itzhak Perlman. “It‟s something I always wanted to play when I grew up, like wanting to be great baseball player,” he said.
1.Law cried on the balcony because .
A. she suffered great pain from the Grade 4 brain cancer
B. Sun refused to get medical treatment after the surgery

Good health is the most valuable thing a person can have, but one cannot take good health for granted. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food ,get enough sleep, and exercise regularly.
Proper nutrition (营养) is important for good health. Your body cannot work well unless it receives the proper kind of “fuel”(燃料).Don't eat too much food with lots of sugar and fat. Eat plenty of foods high in protein (蛋白质) ,like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins (维他命) and minerals. However, don't overeat. It is not helpful to be overweight.
Getting the proper amount of sleep is also important. If you don't get enough sleep, you feel tired and easily get angry. You have no energy. Over a long period of time a little a amount of sleep may even result in a change of personality (人的个性).Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your mind will be sharp.
Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles, and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span (寿命).Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.
If everybody, were to eat the right foods, get plenty of sleep and exercise regularly, the world would be a happier and healthier place. We would all live to be much older and wiser.
1.According to the passage,_________.
A.we should always keep fit |

Zero gravity looks cool. But what about the thing no one likes to talk about? Yes, that is right: going to bathroom. Zero gravity makes this everyday task quite a challenge. Astronauts have to be toilet-trained all over again.
The Apollo astronauts raised themselves off the seat of their chairs and stuck a clear plastic bag to their back sides with sticky strips. A second astronaut watched closely to be sure no waste matter escaped the seal. (You would not want that stuff floating around the cabin!) When the deed was done, the astronaut cleaned up with a piece of plastic attached to the inside of the bag, removed the bag, dropped a disinfectant pill in with the waste matter, and put the whole thing, sealed, into a special container.
Donald W. Rethke, an engineer for Hamilton Standard Space Systems, developed a more private way to answer nature’s call: the space toilet. It is somewhat like the kind of toilet one would find on commercial airplanes --- with unique adaptations for zero gravity, of course. For instance, it has thigh bars that keep the astronaut from floating off the seat.
The astronaut (male or female) defecates (排便) in a bag and urinates (排尿) in a hose. Solid and liquid wastes are kept separated because at least 85% of the urine is recycled and, yes, after careful filtration, used for drinking and other purposes. (Water is always in demand in space.) A vacuum sucks the waste materials into the toilet, where the waste is compacted into hamburger-like patties for easy storage. Although not exactly like an earthbound visit to the toilet, it is at the very least much more private than in the early days of space travel.
1.According to the first paragraph, the lack of the gravity can turn something as simple as _______ into a major challenge.
A. eating B. taking baths
C. sleeping D. answering nature’s call
2.How did astronauts use toilet systems in the Apollo days?
A. None of the waste was separated as it is now.
B. Solid waste was compressed and stored on board.
C. The toilet units used water to remove the waste through the system.
D. The astronauts each used their own private restroom.
3.To ensure the user remains seated, the toilet comes equipped with _______
A. a plastic bag B. a sticky strip
C. a wide hose D. a thigh bar
4.What can be inferred from the fact that most of the astronauts’ urine is recycled?
A. The recycled water tastes better.
B. Water is limited on the space shuttle.
C. It is very convenient to get their urine recycled.
D. Space science includes recycling urine.
