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.2next，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.(in spite of so many warning signs，there are still many victims.look at the following pictures.)3ask students to glance through the text quickly and answer the following questions in exercise 1 on page 58.(1)what is the main topic of this article？which part of the text tells you that?(2)who wrote the article?(3)what do the three pictures show you?(4)where is research
