Explain that we use the present perfect to describe an action that happened (or started) in the past and still has relevance now, in the present. The example on this worksheet tries to emphasise this connection between the past and the present. Go over several examples and help your students write out the structure. Tell them that we don't use specific time expressions (such as yesterday, last week, in 2023 etc.) with the present perfect tense as we don't know or we don't care when the action happened, only if it happened.
Each sentence on the worksheet gives some information about something that happened in the past. Help your students discuss and figure out what must have happened and then form a complete sentence describing it, using the present perfect tense. Check the answers together by reading them out loud.
1) Tom has lost weight.
2) Bill has broken his leg. (Note: make sure they haven't included 'yesterday' in their sentence).
3) My sister has lost her pen.
4) Mary has gone to France.
5) Mr Hill has been in/to Canada.
6) Mrs Smith has bought a lot of packages.
7) I have eaten too much.
8) Mrs Jenkins has cleaned the house.
