句子一般可以分成几个部分，每一个部分在句中具有一定功能，称为句子成分。不同的句子成分由一定的词类或词组充当。
1.主语(Subject)
主语是句子的主体，是一个句子中需要加以说明或者描述的对象。主语一般是由名词、代词、数词、非谓语动词或名词性从句充当。例如：
The plane has just taken off at the airport.
飞机刚从机场起飞。(名词词组作主语)
They are students from the United States.
他们是来自美国的学生。(代词作主语)
Twelve divided by three is four.
十二除以三等于四。(数词作主语)

动名词直接做主语。有时，动名词前可有一个代词或名词所有格表示其逻辑上的主语，有时还可名词化，前面带有冠词。句子的主语除了可用动名词表示之外，还可以用其他成分来表示，如数词、代词、名词、不定式、词组、从句或名词化的其他词类等。it可用作人称代词和非人称代词，也可用来对句子的某一成分加以强调。
