In most cases, noun and verb phrases describe upward and
downward trends. Other trends do not require adjectives or
adverbs much as they are clear on their own. For example, a peak,
a plateau, a period of stability, or a trough may occasionally
require an adjective or an adverb for more clarity.
Number and Amount
In writing task 1, candidates must describe numbers and amounts of different
kinds, such as percentages, proportions, numbers, and rates. Understanding
their differences helps with smoother descriptions. Numbers, amounts, and
percentages generally describe actual quantities of either things or people.
