解釋:

修飾動詞，必須用副詞，修飾名詞，則用形容詞。“Bad”和“good”是形容詞，而“badly”，“poorly”和“well”這類副詞只能用來修飾動詞。

Explanation：

When we use a word to modify a verb，it must be an adverb. When we use a word to modify a noun, it must be an adjective.“Bad” and “good” are adjectives that can be used to describe nouns. “Badly,” “poorly”, and “well” are adverbs that can be used to describe verbs.

Examples:

“My English is good.”

“My English is bad. ”

“My English ability is low.”

“My English ability is high.”

“As an American, l speak English very well. I speak Spanish poorly.”

“Ernest plays ping pong extremely well. He is the school champion.”
