đĄ Exam Tips
âĸ Learn vocabulary in phrases, such as river erosion, air pollution, fossil fuels and prompt action.
âĸ For synonym questions, identify the meaning from the context rather than memorising only one translation.
âĸ Remember the three Rs of environmental protection: reduce, reuse and recycle.
âĸ Use cause-and-effect connectors in writing: because, therefore, as a result, consequently and thus.
âĸ In a paragraph on deforestation, mention loss of trees, increased carbon dioxide, the greenhouse effect and soil erosion.
âĸ For a natural calamity report, include the date, place, cause, damage, casualties and relief activities.
âĸ Distinguish weather from climate: weather is short-term atmospheric condition, while climate is the long-term pattern.
âĸ Use modal verbs for suggestions: should, must, can, may and ought to.
âĸ In gap-filling questions, check grammar as well as meaning before selecting a word.
âĸ Revise noun, verb and adjective forms together, such as polluteâpollutionâpolluted and conserveâconservationâconservative.
