While dealing with the reading material, ask students to pay attention to the reading skills.
Fast reading
Ask students to find the answers to Ex1 using fast reading skills.
T: From the above we can see clearing landmines is challenging. Luckily scientists and engineers have designed a robot to do the job. Now open your books at Page 57 and read the text quickly and then do Ex1.
Explain the two reading skills to students.
Scanning—reading very fast to find specific pieces of information.
Skimming—reading very fast to find only the main ideas of a text.
Five minutes later check the answers with the whole class.
Careful reading
Ask students to read the text carefully and then do Ex1. Students will discuss the answers in groups first, and then check the answers with the whole class.
Ask students to review the facts linked to the figures. Students are asked to work in pairs. Seven minutes later show the suggested answers on the PowerPoint.
Step ⅢDiscussion
Ask students to discuss the text and the following material. Then encourage them to write a letter of suggestion to Bush—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 stop manufacturing landmines and spend more money on solutions to clearing landmines, for example developing new robots to remove the landmines. Step ⅣHomework
Finish writing the letter to President Bush.。
