　　1
　　vacuum cleaner
　　it can move from room to room cleaning your house.you can program it so that it cleans when you are away and you can control what it＂s doing from your computer at the office.
　　2
　　personal robot called ＂papero＂
　　it understands 650 phrases，speaks more than 3000 words.it can recognize different people.it can check your email.it can help children do research on the internet for their homework，talk to them about their day at school and play games.
　　3
　　tiny helicopter
　　it will be used to fly into dangerous areas.for example，it can fly into a house that＂s been destroyed by an earthquake and check if anyone＂s inside.
　　4
　　walking chair
　　it helps people who can＂t walk to go up and down stairs. step 3　reading task1．as we know，robots are designed and built to do a task that is dangerous，uncomfortable，or repetitive for humans.today we are going to read a magazine article about landmines.first，ask students to read this piece of news about landmines.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.landmines，laid by the khmer rouge，the heng samrin and hun sen regimes，the vietnamese，the kpnlf，and the sihanoukists litter the countryside.in most cases，even the soldiers who planted the mines did not record where they were placed.now，cambodia has the one of the highest rates of physical disability of any country 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 1100 years to clear all the mines in the world.2．next，present the students some mine signs and remind students that in spite of so many warning signs，there are still many victims as the pictures show.

　　1introduction：the damage landmines cause·26 000 people killed or badly injured each year·100 million buried in 60 countries·most victims are innocent people
　　2the problem of landmines·each year 100 000 removed·each year 2 000 000 buried·difficult and dangerous to remove
　　3robots can help find traditional mines·much safer in the hunt for landmines·faster at finding landmines·research at chiba university
　　4robots can find plastic mines·experimental robots in production·to use radar to locate mines·to identify types of mines
　　5world opinions turned against landmines in the 1990s·agreement in ottawa，canada to stop the manufacture and use of landmines·still a lot of work to be done step 4　discussion1．first，ask students to read the following materials.from the text we＂ve learned how serious the situation is.many lives are put into danger.so we must do something to improve the situation.as we know，the us hasn＂t yet committed to the mine ban treaty.i hope you will write a letter of suggestion to the president of the us.you may refer to the text2．encourage students to write a letter of suggestion to the president of the us，for the us hasn＂t yet committed to the mine ban treaty.in the letter you will suggest the us should stop manufacturing landmines and spend more money on solutions to clearing landmines，for example developing new robots to remove the landmines.you can refer to the following material：producing one landmine costs $3，yet once in the ground it can cost more than $1000 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 gave rise to them.among the most contaminated countries are iraq，cambodia，afghanistan，colombia，and angola.　　if time is limited，ask students to finish it after class. step 5　homeworkfinish writing the letter to the president of the us.a sample：dear mr.president，i read in the newspaper that the us hasn＂t yet committed to the mine ban treaty.i＂m writing to suggest your country sign on the agreement.1．landmines kill or badly injure around 26 000 people every year.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.i 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 $1000 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.people all over the world will think highly of you and your country.you and your country will become more influential.japan has set a good example.they have developed robots that can be used to clear landmines.i hope your government will follow japan＂s example.thank you for reading the letter.i hope you will consider my suggestions.i believe you also hope the whole world will enjoy peace.let＂s work together and make a peaceful world.yours sincerely，sun cheng
