谓语

谓语（predicate verb）是对主语动作或状态的陈述或说明，指出“做什么”、“是什么”或“怎么样”。谓语动词的位置一般在主语之后。

谓语由动词构成，依据其在句中繁简程度可把谓语分为简单谓语和复合谓语两类。不论何种时态、语态、语气，凡由一个动词（或动词词组）构成的谓语都是简单谓语。

谓语动词一般由动词的各种时态来体现。例如：

I like walking. (一般现在时主动语态)

I made your birthday cake last night. (一般过去时主动语态)

It is used by travellers and business people all over the world. (一般现在时被动语态)

复合谓语也可分为两种情况：

第一种是由情态动词，助动词+不带to的动词不定式构成的复合谓语：

What does this word mean? I won't do it again. You'd better catch a bus.

第二种是由连系动词+表语构成的复合谓语。例如：

The weather gets warmer, and the days get longer. Keep quiet and listen to me. He looked worried.
