确定谓语动词与
非谓语动词的步骤
判断谓语与非谓语
填谓语动词
例:She reads books
句子无其他动词
(考虑时态、语态、
every day.
主谓一致)
(句子中只有一个动词
reads、因此用调语动词)
已有谓语动词
填非谓语动词
例:I enjoy reading books..
且无连词
(确定doing/,done/
(已有谓语动词enjoy,
todo/动名词)
因此用非谓语动词reading)
确定非谓语形式
例:I saw her walking the dog.
逻辑主谓关系
doing
(her与walking是主动关系)
例:The gift is made by my mom.
逻辑动宾关系
done
(The gift与made是被动关系)
