1. Copy one handout for each pair of students, and cut the sheets in two.
2. Put the students into pairs, and distribute a half handout to each individual student.
3. Focus students' attention on the instructions and the verb phrases of accidents given at the bottom of the handout. Explain that some of the accidents happen often to people, whereas others are rare. Elicit the fact that the frequently happening accidents should be connected to the present simple, and the rarer ones to the present perfect. Get students to put them in the correct column and in the correct form (i.e. present perfect).
4. Clarify which verb phrases go in which column (there may be some flexibility in this). Then get your learners to ask and answer the questions together in pairs. Aim for them to use the verb phrases in their responses.
5. Finally, elicit responses from some of the students and draw to their attention any appropriate vocabulary or serious language mistakes.
