动词及基本句型(I)
动词可分为行为动词(也称实义动词)、连系动词等。
行为动词
行为动词有实在的意义,可在句中独立充当谓语,表示动作或状态。行为动词可分为及物动词和不及物动词。
◆ 不及物动词本身意义完整,无需接宾语。由这类动词构成的句子结构为S + V(主+谓)。
e.g. We all laughed. 我们都笑了。
Peter is swimming in the pool now. 彼得现在正在泳池里游泳。
◆ 及物动词本身意义不够完整,后面需接宾语。由这类动词构成的句子结构是 S + V + O (主+谓+宾)。
e.g. Kitty will watch a film this Sunday. 基蒂这个星期天会去看电影。
The restaurant serves many traditional Chinese dishes.
这家餐馆供应许多传统中式菜肴。

连系动词
连系动词主要指 be 动词、感官动词(look、sound、feel、smell、taste)、表示“变,变成” 的动词(become、get、grow、turn)、表示“保持”的动词(remain、keep、stay)和表示“似乎” 的动词(seem、appear)等。
连系动词本身具有词义,但意义不完整,后需接表语。通常结构为 S + V + P (主+系+ 表)。
e.g. He is a teacher. 他是一位教师。
The story sounds very interesting. 这个故事听起来很有趣。
Her face turned red. 她的脸变红了。
China remains unchanged in building good relationships with other countries. 中国同其他国家建立良好关系的决心没有改变。
