在英语中一个简单句只能有一个谓语动词(知道为什么吗),而且,我们平时学习的时态是针对谓语动词来说。如果以do为例,do, did ,have done, will do, had done, is/am/are doing, was/were doing, would do。在简单句中,谓语动词和主语是句子的核心,是不可以随意删掉的。
3、宾语:宾语表示动作的对象或承受者,一般位于及物动词和介词后面。例如:
They went to see an exhibition(展览)yesterday.(名词)
The heavy rain prevented me from coming to school on time.(代词)
How many dictionaries do you have? I have five.(数词)
They helped the old with their housework yesterday.(名词化形容词)
3、下面这些短语只能加doing作宾语:be addicted to, be accustomed to, get down to, lead to ,contribute to, devote oneself to , object to, look forward to, owing to, become/get/be used to, pay attention to等等。
