根据句子成分选用形容词和副词
常见使用形容词的情况:作表语、定语、补语。
He is a careful boy.(作定语,用形容词)
He is careful.(作表语,用形容词)
You must keep your eyes closed. (作宾补,用形容词)。
常用副词的情况:修饰动词、形容词、副词和整个句子。
He writes carefully. He walks slowly.
(认真地写,慢慢地走,修饰动词用副词)
He is probably at home. 他很有可能在家里。
This material is environmentally friendly.(修饰形容词)
He runs very slowly.(修饰副词slowly, 因此very是副词)
Unfortunately, he lost all of his money. (修饰整个句子)
可简单归结为:形修名,表补定;副做状,修“副句形动”(可谐音记为“付诸行动”)。
