Language Tip — Ministry book

Read the Language Tip on deduction (present & past) and the use of should/shouldn't to express blame and regret in the past. Then, study these sentences.

We use modal verbs to say how sure we are — and should / should have to give advice or express regret about the past.

1 The waves must be stronger than before because they sometimes reach the streets.
2 The fishermen might need to change their work methods because the sea is changing.
3 The risks can't be completely avoided, but they can be reduced.
4 Families should take precautions to stay safe during storms.
5 Authorities should continue running awareness campaigns for citizens.
6 People should support renewable energy to reduce pollution.
7 Fishermen should have prepared earlier for the changes in the sea.
8 Citizens should have listened carefully to awareness campaigns in the past.
9 The state should have invested in sea walls many years ago.

  • Body — rising seas · coastal flooding · heat · food and water shortages · economic damage
  • Conclusion — why action now matters for Egypt and the world

Target: 180–200 words · use modal verbs (must/might/can't · should have) where appropriate

Listening strategy

Track 1 = risk & sea levels · Track 2 = families & businesses · Track 3 = fishermen & sea walls. Listen twice before Exercise 1.

🔍

Present vs past deduction

must be (now) vs must have been (past). Evidence in the present → present modals; evidence about yesterday → past modals.

⚖️

Should vs should have

should + base verb = advice now · should have + past participle = regret about the past (e.g. sea walls many years ago).
