Activity 1: Warm-up · 10 minutes
Timeline Chat: Finished or Continuing?
a) Aims
Ss activate prior knowledge of past simple and present perfect and recall the unit's topic of healthy living.
b) Content
Ss look at a timeline on the board that shows last May (finished) and the present (continuing to now). Ss listen to the teacher's model sentences: 'I started walking last May.' and 'I have walked to school since May.' In pairs, Ss ask and answer the questions: 1) When did you start your regular walk or sport? 2) How long have you been doing it? 3) What did you eat for breakfast yesterday? Ss decide which tense they used for each answer.
c) Expected outcomes
Ss identify that 'last May' and 'yesterday' are finished times, requiring past simple, while 'since May' and 'for two months' show a period continuing to now, requiring present perfect. Ss report at least two correct pairs of sentences, e.g., 'I started jogging last September. I have jogged every morning since September.'

Step 1: Task delivering
T draws a timeline with 'last May' on the left, 'now' on the right, and shows the two model sentences. T asks: 'Which action is finished? Which action continues to now?' T gives pairs three questions to ask each other.
Students
Ss look at the timeline and listen. Ss read the three questions and prepare to answer.
Teacher
Step 2: Task performance
T monitors pairs, helps Ss who struggle, and notes useful answers.
Students
Ss ask and answer in pairs. Expected answers: 'I started playing badminton last year.' / 'I have played badminton since last year.' / 'I had rice, eggs and milk for breakfast.'
Teacher
Step 3: Report and discussion
T invites 3 pairs to share. T asks the class: 'Why did you use have for this answer and past simple for that one?'
Students
Ss report their sentences. Expected answer: 'We used the present perfect because the action continues to now, and the past simple because the time is finished.'
Teacher
Step 4: Conclusion and assessment
T confirms the difference: past simple for a finished past time; present perfect for an experience or a period continuing to now. T introduces the topic of the lesson, 'long and healthy life', and links it to regular activity and balanced food.
Students
Ss copy the key idea into their notebooks and say the title of the unit.
