War is expensive and it is bloody. That is why America's Department of Defence wants to replace a third of its armed vehicles and weaponry with robots by2015. Such a change would save money, as robots can be much cheaper to replace than people. Just as importantly for the generals, it would make waging war less prey to the politics of body bags. Nobody mourns a robot.
The US military already routinely uses robotic aero planes known as unmanned aerial vehicles ( UAVs ). In November 2001 two missiles fared from a remote-controlled Predator UAV killed Mohammad Atef, al-Qaeda's chief of military operations and one of Osama bin Laden's most important associates, as he drove his car near Kabul. But whereas UAVs and their ground-based equivalents, such as the machinegun-toting Sword robots, are usually controlled by distant human operators, the Pentagon would like to give these robots increasing amounts of autonomy, including the ability to decide when to use lethal force.
To achieve this, Ronald Arkin of the Georgia Institute of Technology, in Atlanta, is developing a set of rules of engagement for battlefield robots to ensure that their use of lethal force follows the rules of ethics. In other words, he is trying to create an artificial conscience. Dr Arkin believes that there is another reason for putting robots into battle, which is that they have the potential to act more humanely than people. Stress does not affect a robot's judgment in the way it affects a soldier's.
His approach is to create what he calls a "multidimensional mathematical decision-space of possible behavior actions". Based on inputs ranging from radar data and current position to mission status and intelligence feeds, the system would divide the set of all possible actions into those that are ethical and those that are not. If, for example, the drone from which the fatal attack on Atef was launched had sensed that his car was overtaking a school bus, it might then have held fire.
There are comparisons to be drawn between Dr Arkin's work and the famous Three Laws of Robotics drawn up in the 1950s by Isaac Asimov, a science-fiction writer ,to govern robot behaviour. But whereas Asimov's laws were intended to prevent robots from harming people in any circumstances, Dr Arkin's are supposed to ensure only that they are not unethically killed.
This is an admirable goal in theory, but even if ethics can be neatly encoded into software, pitfalls remain. Although a completely rational robot might be unfazed by the chaos and confusion of the battlefield, it could still make mistakes. Surveillance and intelligence data can be wrong, and conditions and situations on the battlefield can change.

Why would an animal kill itself? It seems a strange question, and yet it is one that has made some scientists curious for a long time. For there is a kind of animal called lemming（旅鼠）, that periodically killed themselves together, and no one knows just why!
The small creatures which live in the Scandinavian mountains, feed on a diet of roots and special insects and live in nests they dig underground. When their food supply is large, the lemmings live a normal and undisturbed life.
However, when the lemmings’ food supply becomes too low to support the population, a singular migration（迁徙）begins. The lemmings leave their nests in groups. Great numbers of them begin to travel across the Scandinavian plains, a journey that may last weeks. The lemmings eat everything in their path, continuing their long march until they reach the sea.
The reason for what follows remains unbelievable to naturalists. Upon reaching the coast, the lemmings do not stop but swim by the thousands into the sea. Most stay afloat only a short time before they tire, sink and drown.
A common theory for this mass self-killing is that the lemmings do not realize that the ocean is such a huge body of water in their cross-country journey, the animals must cross many smaller bodies of water, such as rivers and small lakes. They may think that the sea is just another such swimmable path to go through. But no final answer has been found to the strange happening.
1.The passage is mainly about______.
A. how lemmings find food
B. why animals kill themselves
C. the lemmings’ self-killing
D. the food supply in the Scandinavian mountains
2.A reason for the lemmings’ self-killing might be that they______.
A. go mad from a lack of food
B. hope to find fish for food
C. decide to reduce the population
D. think they can cross the sea
3.Why are scientists curious about the lemmings’ behavior?
A. Because they are the only animals that live in Scandinavia.
B. Because it is very unusual for animals to kill themselves.
C. Because of the amount of food they can eat on their march to the sea.
D. Because they can gather together in such huge numbers.
4.The underlined word “singular” means______.
A. unusual B. single C. wonderful D. common

It’s good to make mistakes, and here is why.
First of all, mistakes are a clear sign that we are trying new things. It’s always good to try new things because when we are trying new things, we are growing. If we never try anything new, how can we improve? How can we expand? The simple answer is “We can’t”. Look around us. With very few exceptions, either everything you see in your physical world or every single detail of every single thing is the result of someone trying something new.
Another good thing about mistakes is this: When we are making mistakes, we are learning. Consider this --- Edison failed 10,000 times before he perfected the light bulb. When asked how it felt to fail that many times, he said that he had learned 10,000 things that didn’t work.
Finally, when we make a mistake, we are much closer to success. Why? Because when all is said and done, we will have tried some number of things before we succeeded. Every time we make a mistake, we eliminate one of those things and are one step closer.
But all this doesn’t mean that we should go through life without considering the consequences of a mistake. Quite the contrary, when we try something new, we have to be willing to set some reasonable limits so that in the event that it doesn’t work out the way we want it to, we will be in a position to try again. We all have limited resources --in the form of time and money -- so we shouldn’t blow them all on one approach to a problem. Realize that it probably won’t be perfect the first time and allocate these resources appropriately so we can learn, make corrections, and try it again. Only by accepting and using our mistakes in this way can we make significant advances in our lives.
There is an old saying that goes, “If you’re not making mistakes, you’re not trying hard enough.” So go forth and make mistakes. And learn. And grow. And prosper.
1.From the second paragraph, we can conclude that ________.
A.mistakes are unnecessary for development B.mistakes let us see our own limits
C.it’s common for people to make mistakes D.making mistakes is better than not trying
2.According to the passage, if we try new things, we can ________.
A.move forward B.never fail C.obtain nothing D.be closer to mistakes
3.The underlined word “eliminate” means ________.
A.make up for B.get rid of C.avoid D.solve
4.According to the article, one thing we should pay attention to about making mistakes is ________.
A.avoiding making the same mistakes B.accepting the outcome willingly
C.making proper arrangements for our next try D.reflecting on the consequences after each mistake
5.The article is mainly about ________.
A.how to deal with mistakes B.what benefits making mistakes brings
C.how to achieve success D.how to make use of our mistakes
6.What may the writer probably suggest we say to ourselves when we make a mistake?
A.Never mind, I tried my best. B.That’s all right. I’ll try again.
C.Great! Now I have learned something. D.Look at this mess. Anyone would be upset.
