Suggestions for solutions of waste problem

Instructions:◦ Student A gets Worksheet 3A and student B gets Worksheet

3B.◦ Worksheet 3A and 3B contain different information and you

will need to WORK WITH your partner to write CONDITIONAL SENTENCES about how we can help with the waste problem. You will need to PRESENT your sentences to your classmate later.

◦ Reminder: DO NOT SHOW your worksheet to your partner!!◦ A few tips on conditional sentences:

Type 1: talk about things quite sure, but not 100% Structure: If + present tense, simple future tense.

Type 2: talk about things that you imagine/not true Structure: If + simple past tense, WOULD + base form of a verb

E.g. If everyone in HK reused plastic bags instead of throwing them away, a lot of waste would be reduced.
