Exercise
Choose the correct word from the drop-down list. The word you chose should be suitable for a formal report.

  1. In the past 12 months sales have between 25 and 75.

     

    Answer:
    fluctuated.

    Explanation:

    • 'gone up and down' is too informal
    • 'increased and decreased', 'varied' and 'rose and fell' do not have the meaning of so many changes

  2. Sales from the middle of the year.

     

    Answer:
    fell steeply

    Explanation:

    • 'declined' and 'decreased' do not show how steep the fall was
    • 'went into free-fall' and 'nose-dived' are too dramatic for a formal report

  3. Sales reached a in June.

     

    Answer:
    plateau

    Explanation:
    The correct term is 'plateau'. 'Flat place' and 'level place' are not common trend-description vocabulary.

  4. Sales in .

     

    Answer:
    fell gradually

    Explanation:
    The description should contain 'gradually' to show the rate of change.

  5. Sales in autumn.

    Answer:
    went through a trough

    Explanation:
    The phrase 'in autumn' shows that the time is in the past and has finished, so the past tense is correct.

  6. Sales gradually from January to December.

     

    Answer:
    rose

    Explanation:
    'rose' is the past tense. 'Arose' means 'started'.

  7. There was a in sales in June.

     

    Answer:
    jump

    Explanation:
    Of the options, only 'jump' is used in describing line charts.

  8. There was a decrease in sales in .

     

    Answer:
    dramatic

    Explanation:
    'Dramatic' is an adjective, and adds information to the noun 'decrease'. However, 'drama' is a noun, and dramatically is an adverb, neither of which fit this sentence structure.

  9. Sales steeply last year.

     

    Answer:
    rose

    Explanation:
    Because last year has finished, the past tense is correct. The past tense of 'rise' is 'rose'. 'Raised' is not correct because sales did not 'raise' anything.

  10. Sales leveled off .

     

    Answer:
    in June

    Explanation:
    'Leveled off ' describes the single point where something changed from not level to level.
