Verbs and sentence structures
The basic parts of a sentence are the subject (S) 主语, the verb (V) 谓语动词 and the object (O) 宾语. Usually a statement begins with the subject and the verb. We divide verbs into three kinds: intransitive verbs (vi.) 不及物动词, transitive verbs (vt.) 及物动词 and linking verbs (linking v.) 连系动词.

连系动词主要是指be动词、感官动词(look、sound、feel、smell、taste)和表示“变,变成”的动词(become、get、grow、turn)。
