宾语是指一个动作（动词）的接受者，分为直接宾语和间接宾语两大类，直接宾语指动作的直接对象，间接宾语说明动作的非直接，但受动作影响的对象。一般而言，及物动词后面最少要有一个宾语，而该宾语通常为直接宾语，有些及物动词要求两个宾语，则这两个宾语通常一个为直接宾语，另一个为间接宾语。 ①He didn\'t say anything. ②We sent him a letter. 定语是用来修饰、限定、说明名词或代词的品质与特征的成分。 ①In science, a theory is a reasonable explanation of observed events. ②Possible solutions to the problem are formulated. 一个名词(或其它形式)对另一个名词或代词进行修饰，限定或说明，这个名词（或其它形式）就是同位语。 ①A new household convenience, the icebox, a precursor of the modern refrigerator, had been invented. ②Most of them range in size from $5,000 to $12,500, a welcome sum to many young practitioners. 谓语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”。 ①It is used by travelers and business people all over the world. ②I made your birthday cake last night. 主语是句子陈述的对象，说明是谁或什么，表示句子说的是\"什么人\"或\"什么事\"。 ①My school is not far from my house. ②To do such a job needs more knowledge. 状语是谓语里的另一个附加成分,从情况、时间、处所，方式、条件、对象，肯定、否定、范围和程度等方面对谓语中心（或者整个句子）进行修饰或限制。 ①In a way, any hypothesis is a leap into the unknown. ②It extends the scientist\'s thinking beyond the known facts.
