What did you learn in that activity?

• steep
• plunge
• up and upward = use “up” by itself, but use “upward” with a noun.

E.G. prices were up / an upward trend

• dip
• “erratic” doesn’t really work with “trend”. Instead, you can use “erratic” with “increase” or “decrease”.
• trend = tendency. E.G. The trend has decreased slightly during the last year. There is a gradual increase in the trend of bicycle sales.
• some of these nouns can also be used as verbs such as “peak” and “dip”.
• soar
• don’t forget your articles!!! = before a noun or before an adjective + noun you usually need something like an article, a number, a quantifier (many, a lot etc.) etc.
