This is a worksheet to practice reading skills. There are 5 questions about global warming and 6 answers. Students have to match the right question with the right answer and think what could be the question for the one left out. (answer: What could you do to stop global warming?). You print out the worksheet, separate the answers and questions, mix the answers up and let students match them. You could follow it up with a discussion of what do students think of global warming, how is their country dealing with it and what are they personally doing to stop it. Have fun!
