10) Common mistakes and fixes

• Wrong preposition: increased at → increased by/to
• Over-precision: 23.47% → about 23% (unless exactness is vital)
• Verb repetition: avoid only increase. Rotate rise, climb, grow.
• Numbers without comparison: always show from/to, higher/lower.
• Units missing: add %, kg, million, dollars.

11) 10-minute routine

1. 2 min: read a chart and list 3 verbs, 3 adverbs.
2. 3 min: write two compare sentences using by/to.
3. 3 min: add one fluctuation or plateau sentence.
4. 2 min: check prepositions, units, and variety.

12) Micro glossary table

13) Final checklist

• Do I vary verb + adverb pairs
• Did I use by vs to correctly
• Are units and time clear
• Do sentences compare items, not list numbers
• Is language concise and objective

14) Band 7 plus polish

• Mix clauses: While X rose, Y fell.
• Add extent: a slight increase, a dramatic fall.
• Use cohesive devices: whereas, in contrast, meanwhile.

Last word
Think pattern first, numbers second. Use a small set of strong verbs, add accurate adverbs, and control by/to. With daily micro drills and the Bangla gloss for recall, your Task 1 trends will read clear, precise, and examiner friendly.
