謂語：動詞（助動詞,be動詞...)
表語：形容詞,名詞
賓語：名詞（代名詞,普通名詞...)
暫時可以這么了解,多看看句子,領(lǐng)悟領(lǐng)悟,再深入理解謂語可以由什么組成復(fù)合謂語?1.助動詞/ 情態(tài)動詞 + 實義動詞原形 eg: I do believe I can. I should go home for my homework.
2.be動詞 +形容詞 + to / of / for。。。+動詞原形 / 名詞或動詞現(xiàn)在分式 eg：You are able to do it. The book issuitable for students studing. Nowadays students are short of exercise.
3.系動詞 + 形容詞eg: He looks pale, so I feel worryed.
簡單來說就是這些，要多結(jié)合書本上的例子，更容易記住。
