It can recognize different people. It can check your email and change the TV channel. It can help children do research on the Internet for their homework, talk to them about their day at school, play games, and even dance with them.,Tiny helicopter,It will be used to fly into dangerous areas. For example, it could fly into a house thats been destroyed by an earthquake and check if anyones inside.,Walking chair,It helps people who cant walk to go up and down stairs.,LISTENING TEXT,THE WORLD OF ROBOTS Listen to radio presenter, Alan Dobson (AD), talking to science news reporter, Emma Woods (EW), about robots in todays world.,AD: Now its time for our weekly chat with science news reporter, Emma Woods. Hi Emma. EW: Hi Alan. AD: So, what do you have for us today, Emma?,EW: Well, Alan, I thought wed have a quick look at the world of robots. Often when you talk about robots, people think of science fiction stories; they dont think of robots as part of todays world. AD: Yes, Id agree with that.,EW: Well, we actually already use robots in many industrial but now theyre also being developed for use around the house. Let me tell you about a couple. Theres now a very clever vacuum cleaner that can move from room to room cleaning your house by itself.,You can program it so that it cleans when youre away and you can control what its doing from your computer at the office. AD: I wonder whether it does a good job, but I want one anyway! EW: Well, Alan, youd probably also want a PaPeRo.,AD: A what?

Now whatre you going to talk about next week?,Reading task,Three decades of war in Cambodia have left scars in many forms throughout the country. Unfortunately, one of the most lasting legacies of the conflicts continues to claim new victims daily.,Read this piece of news about landmines.,In most cases, even the soldiers who planted the mines did not record where they were placed. Now, Cambodia has one of the highest rates of physical disability of any countries in the world.,At the current rate of progress, it may take as many as 100 years to clear all the mines in Cambodia, and the UN estimates that with current technology, it will take nearly 1,100 years to clear all the mines in the world.,This is the situation in Cambodia.,Here and there are the mine signs.,In spite of so many warning signs, there are still many victims.,Robots in the fight against landmines.,Fast reading,1. Which part of the text tells you what the main topic of the article is? What is the main topic? 2. Who wrote the article? 3. What do the three pictures show you?,4. Where is research being done on robots that can find landmines? 5. In which two countries might the robots be used?,Careful reading,1. What are the three reasons why landmines are particularly terrible? Landmines kill or badly injure around 26,000 people every year. What is worse is that they keep causing damage for decades after,war ended. There are about 100 million landmines just beneath the surface of the ground in 60 countries. Removing them is very slow and dangerous work that must be done by hand.,2. How are most landmines removed today? By Hand. Someone has to use a mental detector to find the mine. Then he or she has to dig the mine out without setting it off.,3. Why is this method so dangerous? Because the mental detector does not find new types of mine covered in plastic.,4. What are some of the advantages of using the insect-like robot to remove landmines?,As well as being much safer than finding mines by hand, the insect robot is also much faster.,5. What is the robot able to do? It walks on six legs and when it finds a mine, it marks the spot with paint and sends data to a computer which can then map the mines.,6. Why is Chiba University trying to develop a robot that can use radar? The goal is for the computer to use the data it receives to determine not only whether an object is a piece of mental or a mine but also what type of mine it is.,7. What was the result of many countries fighting against the use of landmines? In 1997, 122 countries signed an agreement in Ottawa, Canada, to stop the manufacture and use of landmines.,8. Which sentence does the writer use to emphasize the need to find solutions quickly to removing landmines? Perhaps robotics will provide a solution, but as every 20 minutes goes by, one more person is killed or badly injured.,Discussion,Write a letter of suggestion to Bush-the president of the US, for the US hasnt yet committed to the Mine Ban Treaty.,Material,Producing one landmine costs $3, yet once in the ground it can cost more than $1,000 to find and destroy, according to the ICBL. Over 80 per cent of the 15,000 to 20,000 landmine victims each year are civilians, and at least one in five,are children, according to the International Campaign to Ban Landmines (ICBL). The deadly legacy of landmines far outlasts the conflicts that that gave rise to them. Among the most contaminated countries are Iraq, Cambodia, Afghanistan, Colombia, and Angola.,Homework,Finish writing the letter to President Bush.,A sample:,Sun Cheng China 28 March Dear Mr. President, I read in the newspaper that the US hasnt yet committed to the Mine,Ban Treaty.

There are about 100 million landmines buried just beneath the surface of the ground in 60,countries. Among the most contaminated countries are Iraq, Cambodia, Afghanistan, Colombia, and Angola.think this is one reason why people in these countries hate the US so much. 2. Producing one landmine costs,$3, yet once in the ground it can cost more than $1,000 to find and destroy, according to the ICBL. So stop manufacturing landmines and spend more money on finding solutions to clearing the landmines. As you know, your,country has designed the most advanced robots. Why not use your advanced technology and spend more money on designing some robots to clear the landmines. If so, it will benefit the whole world.
