Robots May Allow Surgery in Space

Small robots designed by University of Nebraska researchers may allow doctors on Earth to help perform. surgery on patients in space.

The tiny, wheeled robots, （51）are about 3 inches tall and as wide as a lipstick case, can be slipped into small incisions(切口)and computer-controlled by surgeons in different locations. Some robots are equipped（52）cameras and lights and can send images back to surgeons and others have surgical tools attached that can be（53）remotely.

“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 so that surgeries could one day be performed in space.

On earth, the surgeons could control the robots themselves（57）other locations. For example, the robots could enable surgeons in other places to （58）on injured soldiers on the front line. Researchers plan tp seek federal regulatory（59）early nest year. Tests on animals have been successful, and tests on humans in England will begin very soon.

The camera-carrying robots can provide（60）of affected areas and the ones with surgical tools will be able to maneuver(操控)inside the body in ways surgeons' hands can't. The views from the camera-carrying robots are （61）than the naked eye, because they（62）back color images that are magnified(放大). Because several robots can be inserted through one incision, they could reduce the amount and （63）of cuts needed for surgery, which would decrease recovery time. This is particularly（64）to those patients who have been debilitated(使虚弱)by long illness.

Eventually, Oleynikov said, the tiny robots may enable surgeons to work without ever（65）their hands in patients' bodies. “That's the goal, ”Oleynikov said. “It's getting easier and easier. We can do even more with these devices. ”

Pressure Cooker (压力锅) Safety

When you are cooking with a pressure cooker, you should learn a few common sense(常识)rules:

1 . Never leave the cooker unwatched when it is in use.

2. Add sufficient liquid but never past the recommended fill point. Overfilling the colder may block the vent pipe (排气孔) and cause the cooker to explode.

3. Set the cooking time. Too much time may overcook the food or too much pressure may build up in the cooker. Too little time will lead to undercooked food.

4. If you are new to pressure cooking, follow the cooking instructions carefully. Heat and time can either result in a great meal or a ruined one.

5. Never try to force a pressure cooker cover open, Allow the cooker to cool or run it under cool water before trying to open the cover.

6. Clean the cooker thoroughly after each use . Mild detergent(洗涤剂)and hot water work the best.

Do not use stove ash or sand for they may damage the cooker. The gasket(密封圈)is best cleaned in warm soapy water and then dried. Store the gasket in the bottom of the pot.

According to the first rule, the user should______ .

Among the annoying challenges facing the middle class is one that will probably gounmentio

ned in the next presidential campaign： What happens when the robots come for theirjobs？

Don‘t dismiss that possibility entirely About half of U.S jobs are at high risk of beingautomated， according to a University of Oxford study， with the middle class disproportionatelysqueezed Lower-income jobs like gardening or day care don’t appeal to robots But manymiddle-class occupations-trucking， financial advice， software engineering — have arousedtheir interest， or soon will The rich own the robots， so they will be fine.

This isn‘t to be alarmist Optimists point out that technological upheaval has benefitedworkers in the past The Industrial Revolution didn’t go so well for Luddites whose jobs weredisplaced by mechanized looms， but it eventually raised living standards and created more jobsthan it destroyed Likewise， automation should eventually boost productivity， stimulatedemand by driving down prices， and free workers from hard， boring work But in the mediumterm， middle-class workers may need a lot of help adjusting.

The first step， as Erik Brynjolfsson and Andrew McAfee argue in The Second Machine Age，should be rethinking education and job training Curriculums —from grammar school tocollege- should evolve to focus less on memorizing facts and more on creativity and complexcommunication Vocational schools should do a better job of fostering problem-solving skillsand helping students work alongside robots Online education can supplement the traditionalkind It could make extra training and instruction affordable Professionals trying to acquirenew skills will be able to do so without going into debt.

The challenge of coping with automation underlines the need for the U.S to revive itsfading business dynamism： Starting new companies must be made easier In previous eras ofdrastic technological change， entrepreneurs smoothed the transition by dreaming up ways tocombine labor and machines The best uses of 3D printers and virtual reality haven‘t beeninvented yet The U.S needs the new companies that will invent them.

Finally， because automation threatens to widen the gap between capital income and laborincome， taxes and the safety net will have to be rethought Taxes on low-wage labor need tobe cut， and wage subsidies such as the earned income tax credit should be expanded： Thiswould boost incomes， encourage work， reward companies for job creation， and reduceinequality.

Technology will improve society in ways big and small over the next few years， yet this willbe little comfort to those who find their lives and careers upended by automation Destroyingthe machines that are coming for our jobs would be nuts But policies to help workers adapt willbe indispensable.

Who will be most threatened by automation？

A.Leading politicians

B.Low-wage laborers

C.Robot owners

D.Middle-class workers

Education in the age of automation should put more emphasis onA.creative potential

B.job-hunting skills

C.individual needs

D.cooperative spirit

Which of the following best represent the author’s view？A.Worries about automation are in fact groundless

B.Optimists‘ opinions on new tech find little support

C.Issues arising from automation need to be tackled

D.Negative consequences of new tech can be avoided

The author suggests that tax policies be aimed atA.encouraging the development of automation

B.increasing the return on capital investment

C.easing the hostility between rich and poor

D.preventing the income gap from widening

In this text， the author presents a problem withA.opposing views on it

B.possible solutions to it

C.its alarming impacts

D.its major variations

Trees should only be pruned （修剪, 整枝) when there is a good and clear reason for doing s

Trees should only be pruned (修剪, 整枝) when there is a good and clear reason for doing so and, fortunately, the number of such reasons is small. Pruning involves the cutting away of overgrown and unwanted branches, and the inexperienced gardener can be encouraged by the thought that more damage results from doing it unnecessarily than from leaving the tree to grow in its own way. First, pruning may be done to make sure that trees have a desired shape or size. The object may be to get a tree of the right height, and at the same time to help the growth of small side branches which will thicken its appearance or give it a special shape. Secondly, pruning may be done to make the tree healthier. You may cut out diseased or dead wood, or branches that are rubbing against each other and thus causing wounds. The health of a tree may be encouraged by removing branches that are blocking up the centre and so preventing the free movement of air. One result of pruning is that an open wound is left on the tree and this provides an easy entry for disease, but it is a wound that will heal. Often there is a race between the healing and the disease as to whether the tree will live or die, so that there is a period when the tree is at risk. It should be the aim of every gardener to reduce that risk of death as far as possible. It is essential to make the wound on the tree which has been pruned smooth and clean for healing will be slowed down by roughness. You should allow the cut surface to dry for a few hours and then paint it with one of the substances available from garden shops produced especially for this purpose. Pruning is usually done in winter, for then you can see the shape of the tree clearly without interference from the leaves and it is. too very unlikely that the cuts you make will bleed. If this does happen, it is, of course, impossible to paint them properly.

Pruning is probably usually done to______.

A．make the small branches thicker

B．get rid of the small branches

C．improve the shape of the tree

D．make the tree grow taller
