该句型中的谓语动词是系动词。系动词后接的部分可称为表语，也可称为(主语)补足语，主语补足语这一部分的主要功能是对主语进行说明、补充。英文中的系动词主要指Be动词的各种变化形式，也包括那些有时起系动词作用的实义动词。此类动词常见的有：become(变成), look(看上去), seem(看起来), appear(相似、显得), get(变得), feel(摸起来), grow(变得), turn(变成), remain(仍然是), come(变得), fall(变得), hold(保持), keep(保持), stand(保持), stay(保持), smell(闻起来), sound(听起来), taste(尝起来)等。

二、主语-动词-宾语 (SVO)

该句型中的谓语动词是及物动词，那么它必须带有自己的宾语。在英文中，当一个动词(包括单个动词和动词短语)作及物动词用时，它必须要有自己的宾语(除非是宾语在上下文里很明确地提到过，为避免不必要的重复，才会省去。)，否则会视为“句子不完整”。

三 、主语-动词-宾语-宾语 (SVOO)

该句型中的谓语动词后接两个宾语：前一个宾语称为“间接宾语”，多由代词或名词充当;后一个宾语称为“直接宾语”，往往由名词充当。常见的这类谓语动词有： give(给某人……), bring(带给某人……), tell(告诉某人……), send(送给某人……), leave(留给某人……), pass(递给某人……), read(给某人读……), write(给某人写……), take(给某人拿……), show(给某人看……), teach(教某人……), get(给某人弄到……), award(授予某人……),lend(借给某人……), rent(租赁某人……), buy(给某人买……), pay(支付某人……), hand(递给某人……), recommend(将某人推荐给……)等。
