一个英语句子中两个动词之间一定要用to来连接吗

在一个句子中出现两个或两个以上的动词时候,有以下几种处理方式
1,使用并列连接and 来做并列谓语
例如, He sings and dances well.
2, 确定一个做主句的谓语动词,一个做从句的谓语动词
例如. The boy is playing over there, who does well in English.
3, 使用非谓语形式（包括不定式,ing形式和过去分词）做主语,宾语,表语,补语,状语,定语等
例如. I want to have a rest. (to have a rest 做want的宾语)
He likes dancing.(dancing 做like的宾语)
smoking is harmful. （smoking做主语）
Dad told me to come back early.(to come back 做宾语补足语)
My aim is to be a teacher. (to be a teacher 做表语)
The boy playing over there is my brother. (playing over there 做the boy 的定语)
seen from the top of the mountain, this park is very beautiful.(seen.做整个句子的状语)

希望对你有些帮助

如果是并列关系的话用and连接。如果不是并列关系的话，则用to连接。有时如果是固定搭配的话也会用动名词doing.

不一定
